Subject: [PATCH 0001/2948] gfs2: Rename GLF_VERIFY_EVICT to GLF_VERIFY_DELETE

Rename the GLF_VERIFY_EVICT flag to GLF_VERIFY_DELETE: that flag
indicates that we want to delete an inode / verify that it has been
deleted.

To match, rename gfs2_queue_verify_evict() to
gfs2_queue_verify_delete().

Subject: [PATCH 0002/2948] gfs2: Initialize gl_no_formal_ino earlier

Set gl_no_formal_ino of the iopen glock to the generation of the
associated inode (ip->i_no_formal_ino) as soon as that value is known.
This saves us from setting it later, possibly repeatedly, when queuing
GLF_VERIFY_DELETE work.

Subject: [PATCH 0003/2948] perf test: Be more tolerant of metricgroup failures

Previously "set -e" meant any non-zero exit code from perf stat would
cause a test failure. As a non-zero exit happens when there aren't
sufficient permissions, check for this case and make the exit code
2/skip for it.

Subject: [PATCH 0004/2948] perf cs-etm: Don't flush when packet_queue fills up

cs_etm__flush(), like cs_etm__sample() is an operation that generates a
sample and then swaps the current with the previous packet. Calling
flush after processing the queues results in two swaps which corrupts
the next sample. Therefore it wasn't appropriate to call flush here so
remove it.

Flushing is still done on a discontinuity to explicitly clear the last
branch buffer, but when the packet_queue fills up before reaching a
timestamp, that's not a discontinuity and the call to
cs_etm__process_traceid_queue() already generated samples and drained
the buffers correctly.

This is visible by looking for a branch that has the same target as the
previous branch and the following source is before the address of the
last target, which is impossible as execution would have had to have
gone backwards:

  ffff800080849d40 _find_next_and_bit+0x78 => ffff80008011cadc update_sg_lb_stats+0x94
   (packet_queue fills here before a timestamp, resulting in a flush and
    branch target ffff80008011cadc is duplicated.)
  ffff80008011cb1c update_sg_lb_stats+0xd4 => ffff80008011cadc update_sg_lb_stats+0x94
  ffff8000801117c4 cpu_util+0x24 => ffff8000801117d4 cpu_util+0x34

After removing the flush the correct branch target is used for the
second sample, and ffff8000801117c4 is no longer before the previous
address:

  ffff800080849d40 _find_next_and_bit+0x78 => ffff80008011cadc update_sg_lb_stats+0x94
  ffff80008011cb1c update_sg_lb_stats+0xd4 => ffff8000801117a0 cpu_util+0x0
  ffff8000801117c4 cpu_util+0x24 => ffff8000801117d4 cpu_util+0x34

Make sure that a final branch stack is output at the end of the trace
by calling cs_etm__end_block(). This is already done for both the
timeless decode paths.

Subject: [PATCH 0005/2948] perf cs-etm: Use new OpenCSD consistency checks

Previously when the incorrect binary was used for decode, Perf would
silently continue to generate incorrect samples. With OpenCSD 1.5.4 we
can enable consistency checks that do a best effort to detect a mismatch
in the image. When one is detected a warning is printed and sample
generation stops until the trace resynchronizes with a good part of the
image.

Subject: [PATCH 0011/2948] perf evsel: display dmesg command of showing a
 hardcoded path

In non-FHS compliant distros like NixOS, nothing resides in `/bin`
and `/usr/bin`. Instead dynamically symlinked into
`/run/current-system/sw/bin/`, the executable resides in `/nix/store`.

With this patch,`/bin` prefix from the dmesg command in the error
message is stripped.

Subject: [PATCH 0012/2948] gfs2: Allow immediate GLF_VERIFY_DELETE work

Add an argument to gfs2_queue_verify_delete() that allows it to queue
GLF_VERIFY_DELETE work for immediate execution.  This is used in the
next patch.

Subject: [PATCH 0013/2948] gfs2: Fix unlinked inode cleanup

Before commit f0e56edc2ec7 ("gfs2: Split the two kinds of glock "delete"
work"), function delete_work_func() was used to trigger the eviction of
in-memory inodes from remote as well as deleting unlinked inodes at a
later point.  These two kinds of work were then split into two kinds of
work, and the two places in the code were deferred deletion of inodes is
required accidentally ended up queuing the wrong kind of work.  This
caused unlinked inodes to be left behind, which could in the worst case
fill up filesystems and require a filesystem check to recover.

Fix that by queuing the right kind of work in try_rgrp_unlink() and
gfs2_drop_inode().

Fixes: f0e56edc2ec7 ("gfs2: Split the two kinds of glock "delete" work")

Subject: [PATCH 0014/2948] perf stat: Close cork_fd when
 create_perf_stat_counter() failed

When create_perf_stat_counter() failed, it doesn't close workload.cork_fd
open in evlist__prepare_workload(). This could make too many open file
error while __run_perf_stat() repeats.

Introduce evlist__cancel_workload to close workload.cork_fd and
wait workload.child_pid until exit to clear child process
when create_perf_stat_counter() is failed.

Exit when run_perf_stat() returns an error to avoid continuously
repeating the same error message. It's not expected that COUNTER_FATAL
or internal errors are recoverable so there's no point in retrying.

This fixes the following flood of error messages for permission issues,
for example when perf_event_paranoid==3:
  perf stat -r 1044 -- false

  Error:
  Access to performance monitoring and observability operations is limited.

Subject: [PATCH 0017/2948] perf symbol: Do not fixup end address of labels

When it loads symbols from an ELF file, it loads label symbols which is
0 size.  Sometimes it has the same address with other symbols and might
shadow the original symbols because it fixes up the size of the symbol.

For example, in my system __do_softirq is shadowed and only accepts the
__softirqentry_text_start instead.  But it should accept __do_softirq.

  $ readelf -sW vmlinux | grep -e __do_softirq -e __softirqentry_text_start
  105089: ffffffff82000000   814 FUNC    GLOBAL DEFAULT    1 __do_softirq
  111954: ffffffff82000000     0 NOTYPE  GLOBAL DEFAULT    1 __softirqentry_text_start

  $ perf annotate --stdio __do_softirq
  Error:
  The perf.data data has no samples!

  $ perf annotate --stdio __softirqentry_text_start | head
   Percent |	Source code & Disassembly of vmlinux for cycles (26 samples, percent: local period)
  ---------------------------------------------------------------------------------------------------
           : 0                0xffffffff82000000 <__softirqentry_text_start>:
      0.00 :   ffffffff82000000:        nopl    (%rax,%rax)
     30.77 :   ffffffff82000005:        pushq   %rbp
      3.85 :   ffffffff82000006:        movq    %rsp, %rbp
      0.00 :   ffffffff82000009:        pushq   %r15
      3.85 :   ffffffff8200000b:        pushq   %r14
      3.85 :   ffffffff8200000d:        pushq   %r13
      0.00 :   ffffffff8200000f:        pushq   %r12

We can ignore NOTYPE symbols in the symbols__fixup_end() so that it can
pick the __do_softirq() in choose_best_symbol().  This should be fine
since most symbols have either STT_FUNC or STT_OBJECT.

Subject: [PATCH 0018/2948] perf test: Ignore security failures in all PMU test

Refactor code to have some more error diagnosis on traps, etc. and to
do less work on each line. Add an ignore situation for security failures.

Subject: [PATCH 0019/2948] perf evsel: Add alternate_hw_config and use in
 evsel__match

There are cases where we want to match events like instructions and
cycles with legacy hardware values, in particular in stat-shadow's
hard coded metrics. An evsel's name isn't a good point of reference as
it gets altered, strstr would be too imprecise and re-parsing the
event from its name is silly. Instead, hold the legacy hardware event
name, determined during parsing, in the evsel for this matching case.

Inline evsel__match2 that is only used in builtin-diff.

Subject: [PATCH 0020/2948] perf stat: Uniquify event name improvements

Without aggregation on Intel:
```
$ perf stat -e instructions,cycles ...
```
Will use "cycles" for the name of the legacy cycles event but as
"instructions" has a sysfs name it will and a "[cpu]" PMU suffix. This
often breaks things as the space between the event and the PMU name
look like an extra column. The existing uniquify logic was also
uniquifying in cases when all events are core and not with uncore
events, it was not correctly handling modifiers, etc.

Change the logic so that an initial pass that can disable
uniquification is run. For individual counters, disable uniquification
in more cases such as for consistency with legacy events or for
libpfm4 events. Don't use the "[pmu]" style suffix in uniquification,
always use "pmu/.../". Change how modifiers/terms are handled in the
uniquification so that they look like parse-able events.

This fixes "102: perf stat metrics (shadow stat) test:" that has been
failing due to "instructions [cpu]" breaking its column/awk logic when
values aren't aggregated. This started happening when instructions
could match a sysfs rather than a legacy event, so the fixes tag
reflects this.

Fixes: 617824a7f0f7 ("perf parse-events: Prefer sysfs/JSON hardware events over legacy")

Subject: [PATCH 0021/2948] perf stat: Remove evlist__add_default_attrs use
 strings

add_default_atttributes would add evsels by having pre-created
perf_event_attr, however, this needed fixing for hybrid as the
extended PMU type was necessary for each core PMU. The logic for this
was in an arch specific x86 function and wasn't present for ARM,
meaning that default events weren't being opened on all PMUs on
ARM. Change the creation of the default events to use parse_events and
strings as that will open the events on all PMUs.

Rather than try to detect events on PMUs before parsing, parse the
event but skip its output in stat-display.

The previous order of hardware events was: cycles,
stalled-cycles-frontend, stalled-cycles-backend, instructions. As
instructions is a more fundamental concept the order is changed to:
instructions, cycles, stalled-cycles-frontend, stalled-cycles-backend.

Subject: [PATCH 0023/2948] perf evsel: Remove pmu_name

"evsel->pmu_name" is only ever assigned a strdup of "pmu->name", a
strdup of "evsel->pmu_name" or NULL. As such, prefer to use
"pmu->name" directly and even to directly compare PMUs than PMU
names. For safety, add some additional NULL tests.

Subject: [PATCH 0024/2948] perf test: Make stat test work on DT devices

PMUs aren't listed in /sys/devices/ on DT devices, so change the search
directory to /sys/bus/event_source/devices which works everywhere. Also
add armv8_cortex_* as a known PMU type to search for to make the test
run on more devices.

Subject: [PATCH 0025/2948] perf test: Add a test for default perf stat command

Test that one cycles event is opened for each core PMU when "perf stat"
is run without arguments.

The event line can either be output as "pmu/cycles/" or just "cycles" if
there is only one PMU. Include 2 spaces for padding in the one PMU case
to avoid matching when the word cycles is included in metric
descriptions.

Subject: [PATCH 0026/2948] libperf: Explicitly specify install-html
 dependencies

install_doc of tools/lib/perf/Makefile invokes install-man,
install-html, and install-examples of
tools/lib/perf/Documentation/Makefile at once. This invocation succeeds
when make runs in serial but can fail when make runs in parallel because
while install-man of tools/lib/perf/Documentation/Makefile depends on
all, install-html depends on nothing and can run ahead of all.

Explicitly specify the dependencies of install-html to ensure that
they are resolved before install-html.

Subject: [PATCH 0027/2948] perf sched replay: Remove unused parts of the code

The sleep_sem semaphore and the specific_wait field (member of sched_atom)
are initialized but not used anywhere in the code, so this patch removes
them.

The SCHED_EVENT_MIGRATION case in perf_sched__process_event() is currently
not used and is also removed.

Additionally, prev_state in add_sched_event_sleep() is marked with
__maybe_unused and is not utilized anywhere in the function. This patch
removes the parameter.

If the task_state parameter was intended for future use, it can be
reintroduced when needed.

No functionality change intended.

Subject: [PATCH 0028/2948] perf mem: Fix printing PERF_MEM_LVLNUM_{L2_MHB|MSC}

With commit 8ec9497d3ef34 ("tools/include: Sync uapi/linux/perf.h
with the kernel sources"), 'perf mem report' gives an incorrect memory
access string.
...
0.02%	1	3644	L5 hit	[.] 0x0000000000009b0e	mlc	[.] 0x00007fce43f59480
...

This occurs because, if no entry exists in mem_lvlnum, perf_mem__lvl_scnprintf
will default to 'L%d, lvl', which in this case for PERF_MEM_LVLNUM_L2_MHB is 0x05.
Add entries for PERF_MEM_LVLNUM_L2_MHB and PERF_MEM_LVLNUM_MSC to mem_lvlnum,
so that the correct strings are printed.
...
0.02%	1	3644	L2 MHB hit	[.] 0x0000000000009b0e	mlc	[.] 0x00007fce43f59480

Subject: [PATCH 0029/2948] perf/test: Speed up test case perf annotate basic
 tests

perf test 70 takes a long time. One culprit is the output of command
perf annotate. Per default enabled are
 - demangle symbol names
 - interleave source code with assembly code.
Disable demangle of symbols and abort the annotation
after the first 250 lines.

This speeds up the test case considerable, for example
on s390:

Output before:
 # time  perf test 70
 70: perf annotate basic tests             : Ok
 .....
 real   2m7.467s
 user   1m26.869s
 sys    0m34.086s
 #

 Output after:
 # time perf test 70
 70: perf annotate basic tests             : Ok

 real   0m3.341s
 user   0m1.606s
 sys    0m0.362s

 touchscreen

Extend the novatek touchscreen driver to support NT36672A chip which
is found in phones like qcom/sdm845-xiaomi-beryllium-tianma.dts.
Added devicetree support for the driver and used i2c chip data to handle
the variation in chip id and wake type. Also added vcc and iovcc
regulators which are used to power the touchscreen hardware.

Subject: [PATCH 0080/2948] iio: pressure: bmp280: Add support for bmp280 soft
 reset

The BM(P/E)28x devices have an option for soft reset which is also
recommended by the Bosch Sensortech BME2 Sensor API to be used before the
initial configuration of the device.

Subject: [PATCH 0081/2948] iio: pressure: bmp280: Remove config error check
 for IIR filter updates

When there is a change in the configuration of the BMP3xx device, several
steps take place. These steps include:

1) Update the OSR settings and check if there was an update
2) Update the ODR settings and check if there was an update
3) Update the IIR settings and check if there was an update
4) Check if there was an update with the following procedure:
	a) Set sensor to SLEEP mode and after to NORMAL mode to trigger
	   a new measurement.
	b) Wait the maximum amount possible depending on the OSR settings
	c) Check the configuration error register if there was an error
	   during the configuration of the sensor.

This check is necessary, because there could be a case where the OSR is
too high for the requested ODR so either the ODR needs to be slower or the
OSR needs to be less. This is something that is checked internally by the
sensor when it runs in NORMAL mode.

In the BMP58x devices the previous steps are done internally by the sensor.

The IIR filter settings do not depend on the OSR or ODR settings, and there
is no need to run a check in case they change.

This is easier to scan quickly compared to bitwise manipulation, and
it is pleasingly symmetric.

Subject: [PATCH 0084/2948] iio: adc: Constify struct iio_map

'struct iio_map' are not modified in these drivers.

Constifying this structure moves some data to a read-only section, so
increase overall security.

In order to do it, the prototype of iio_map_array_register() and
devm_iio_map_array_register(), and a few structures that hold a
"struct iio_map *" need to be adjusted.

On a x86_64, with allmodconfig, as an example:
Before:

After:

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit adds bindings support for AD4113.

The AD4113 is a low power, low noise, 16-bit, Σ-Δ analog-to-digital
converter (ADC) that integrates an analog front end (AFE) for four
fully differential or eight single-ended inputs.

Added ad4113 to the compatible list and the "avdd2-supply: false"
restriction.

Subject: [PATCH 0089/2948] iio: temperature: tmp006: add triggered buffer
 support

Add support for continuous data capture using triggered buffers for the
tmp006 sensor. The device features a "data ready" interrupt line which
is pulled down once a new measurement is ready to be read.

Subject: [PATCH 0093/2948] iio: proximity: vl53l0x-i2c: Added sensor ID check

The commit adds a check for the sensor's model ID. We read the model
identification register (0xC0) and expect a value of 0xEE.

Subject: [PATCH 0094/2948] iio: proximity: vl53l0x-i2c: Added continuous mode
 support

The continuous mode of the sensor is enabled in the buffer_postenable.
Replaced the original irq handler with a threaded irq handler to perform
i2c reads during continuous mode.
The continuous mode is disabled by disabling the buffer.
Added a trigger for this device to be used for continuous mode.

Subject: [PATCH 0095/2948] iio: light: al3010: Fix an error handling path in
 al3010_probe()

If i2c_smbus_write_byte_data() fails in al3010_init(),
al3010_set_pwr(false) is not called.

In order to avoid such a situation, move the devm_add_action_or_reset()
witch calls al3010_set_pwr(false) right after a successful
al3010_set_pwr(true).

Subject: [PATCH 0096/2948] iio: imu: kmx61: Drop most likely fake ACPI ID

The commit in question does not proove that ACPI ID exists.
Quite likely it was a cargo cult addition while doint that
for DT-based enumeration.  Drop most likely fake ACPI ID.

Googling for KMX61021L gives no useful results in regard to DSDT.
Moreover, the official vendor ID in the registry for Kionix is KIOX.

From a976ef24c62540d6dd166a93e474684ae5463455 Mon Sep 17 00:00:00 2001
From: Mariel Tinaco <Mariel.Tinaco@analog.com>
Date: Thu, 12 Sep 2024 17:54:35 +0800
Subject: [PATCH 0100/2948] iio: dac: support the ad8460 Waveform DAC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The AD8460 is a “bits in, power out” high voltage, high-power,
high-speed driver optimized for large output current (up to ±1 A)
and high slew rate (up to ±1800 V/μs) at high voltage (up to ±40 V)
into capacitive loads.

A digital engine implements user-configurable features: modes for
digital input, programmable supply current, and fault monitoring
and programmable protection settings for output current,
output voltage, and junction temperature. The AD8460 operates on
high voltage dual supplies up to ±55 V and a single low voltage
supply of 5 V.

Subject: [PATCH 0101/2948] dt-bindings: iio: adc: amlogic,meson-saradc: also
 allow meson8-saradc to have amlogic,hhi-sysctrl property

The SARADC on the Amlogic Meson8 SoC also requires the amlogic,hhi-sysctrl,
property, document it by adding the amlogic,meson8-saradc compatible in the
adequate allOf:if:compatible:contains:enums along meson8b and meson8m2.

Subject: [PATCH 0102/2948] iio: adc: ad7606: add 'bits' parameter to channels
 macros

There are some newer additions to the AD7606 family, which support 18 bit
precision. Up until now, all chips were 16 bit.

This change adds a 'bits' parameter to the AD760X_CHANNEL macro and renames
'ad7606_channels' -> 'ad7606_channels_16bit' for the current devices.

The AD7606_SW_CHANNEL() macro is also introduced, as a short-hand for IIO
channels in SW mode.

Subject: [PATCH 0103/2948] iio: adc: ad7606: move 'val' pointer to
 ad7606_scan_direct()

The ad7606_scan_direct() function returns 'int', which is fine for 16-bit
samples.
But when going to 18-bit samples, these need to be implemented as 32-bit
(or int) type.

In that case when getting samples (which can be negative), we'd get random
error codes.
So, the easiest thing is to just move the 'val' pointer to
'ad7606_scan_direct()'. This doesn't qualify as a fix, it's just a
preparation for 18-bit ADCs (of the AD7606 family).

Subject: [PATCH 0104/2948] iio: adc: ad7606: move scale_setup as function
 pointer on chip-info

Up until now, all ADCs were 16-bit precision.
With the addition of the AD7606C some things will change. For one thing,
we'll need to setup available-scales for each channel. Also for the 18-bit
precision variants, the scales will be different.

This change adds a function-pointer to the chip-info struct to be able to
set this up (differently) for the new parts. For the current parts, the
scales are the same (for all parts) between HW and SW modes.

Also creating a 'ad7606_sw_mode_setup()' function that must be called
before the scale_setup callback. This is needed in case SW mode is enabled
for some ADCs.

Subject: [PATCH 0105/2948] iio: adc: ad7606: wrap channel ranges & scales into
 struct

With the addition of AD7606C-16,18 which have differential & bipolar
channels (and ranges), which can vary from channel to channel, we'll need
to keep more information about each channel range.

To do that, we'll add a 'struct ad7606_chan_scale' type to hold just
configuration for each channel.
This includes the scales per channel (which can be different with
AD7606C-16,18), as well as the range for each channel.
This driver was already keeping the range value for each channel before,
and since this is couple with the scales, it also makes sense to put them
in the same struct.

Subject: [PATCH 0106/2948] iio: adc: ad7606: rework available attributes for
 SW channels

For SW mode, the oversampling and scales attributes are always present.
So, they can be implemented via a 'read_avail' hook in iio_info.

For HW mode, it's a bit tricky, as these attributes get assigned based on
GPIO definitions.

So, for SW mode, we define a separate AD7606_SW_CHANNEL() macro, and use
that for the SW channels.
And 'ad7606_info_os_range_and_debug' can be renamed to
'ad7606_info_sw_mode' as it is only used for SW mode.

For the 'read_avail' hook, we'll need to allocate the SW scales, so that
they are just returned userspace without any extra processing.
The allocation will happen when then ad7606_state struct is allocated.
The oversampling available parameters don't need any extra processing; they
can just be passed back to userspace (as they are).

 corner case for some ADCs

Some ADCs have channels with negative and positive inputs, which can be
used to measure differential voltage levels. These inputs/pins are
dedicated (to the given channel) and cannot be muxed as with other ADCs.

For those types of setups, the 'diff-channels' property can be specified to
be used with the channel number (or reg property) for both negative and
positive inputs/pins.

Subject: [PATCH 0112/2948] remoteproc: k3: Call of_node_put(rmem_np) only once
 in three functions

An of_node_put(rmem_np) call was immediately used after a pointer check
for a of_reserved_mem_lookup() call in three function implementations.
Thus call such a function only once instead directly before the checks.

This issue was transformed by using the Coccinelle software.

An iommu domain is allocated in rproc_enable_iommu() and is attached to
rproc->dev.parent in the same function.

Use iommu_paging_domain_alloc() to make it explicit.

 functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

pci_hp_deregister() was converted to void by the commit 51bbf9bee34f ("PCI:
hotplug: Demidlayer registration with the core") but its kerneldoc still
describes the return value. pci_hp_del() and pci_hp_destroy() have been
void since they were introduced in that same commit.

Remove the return value description from the kerneldoc of those functions.

Subject: [PATCH 0117/2948] perf vender events arm64: Use "Topdown" as topdown
 metric group name

HiSilicon HIP08 does support Topdown metrics but perf tool complains
when trying to count Topdown metrics:
[root@localhost tracing]# perf stat --topdown
Topdown requested but the topdown metric groups aren't present.
(See perf list the metric groups have names like TopdownL1)

It's because tool's using "Topdown" as the metric group name[1] rather
than "TopDown", so follow the convention. This is introduced by [2]
which allows to use json metrics to support --topdown function.

[1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/perf/builtin-stat.c?h=v6.11-rc1#n1994
[2] commit 1647cd5b8802 ("perf stat: Implement --topdown using json metrics")

Subject: [PATCH 0119/2948] perf x86/topdown: Complete topdown slots/metrics
 events check

It's not complete to check whether an event is a topdown slots or
topdown metrics event by only comparing the event name since user
may assign the event by RAW format, e.g.

perf stat -e '{instructions,cpu/r400/,cpu/r8300/}' sleep 1

 Performance counter stats for 'sleep 1':

     <not counted>      instructions
     <not counted>      cpu/r400/
   <not supported>      cpu/r8300/

       1.002917796 seconds time elapsed

       0.002955000 seconds user
       0.000000000 seconds sys

The RAW format slots and topdown-be-bound events are not recognized and
not regroup the events, and eventually cause error.

Thus add two helpers arch_is_topdown_slots()/arch_is_topdown_metrics()
to detect whether an event is topdown slots/metrics event by comparing
the event config directly, and use these two helpers to replace the
original event name comparisons.

Subject: [PATCH 0120/2948] perf x86/topdown: Correct leader selection with
 sample_read enabled

Addresses an issue where, in the absence of a topdown metrics event
within a sampling group, the slots event was incorrectly bypassed as
the sampling leader when sample_read was enabled.

perf record -e '{slots,branches}:S' -c 10000 -vv sleep 1

In this case, the slots event should be sampled as leader but the
branches event is sampled in fact like the verbose output shows.

perf_event_attr:
  type                             4 (cpu)
  size                             168
  config                           0x400 (slots)
  sample_type                      IP|TID|TIME|READ|CPU|IDENTIFIER
  read_format                      ID|GROUP|LOST
  disabled                         1

  size                             168
  config                           0x4 (PERF_COUNT_HW_BRANCH_INSTRUCTIONS)
  { sample_period, sample_freq }   10000

  sample_id_all                    1
  exclude_guest                    1

The sample period of slots event instead of branches event is reset to
0.

This fix ensures the slots event remains the leader under these
conditions.

Error:
The sys_perf_event_open() syscall returned with 22 (Invalid argument) for
event (topdown-retiring).

The reason of error is that the events are regrouped and
topdown-retiring event is moved to closely after the slots event and
topdown-retiring event needs to do the sampling, but Intel PMU driver
doesn't support to sample topdown metrics events.

For topdown metrics events, it just requires to be in a group which has
slots event as leader. It doesn't require topdown metrics event must be
closely after slots event. Thus it's a overkill to move topdown metrics
event closely after slots event in events regrouping and furtherly cause
the above issue.

Thus don't move topdown metrics events forward if they are already in a
group.

to describe. Hence, bring back the description from the previous binding
to the current one along with a bit more context on what the values are
supposed to be.

+description: |
+  Please refer to pinctrl-bindings.txt in this directory for details of the
+  common pinctrl bindings used by client devices, including the meaning of the
+  phrase "pin configuration node".
+
+  Versal's pin configuration nodes act as a container for an arbitrary number of
+  subnodes. Each of these subnodes represents some desired configuration for a
+  pin, a group, or a list of pins or groups. This configuration can include the
+  mux function to select on those pin(s)/group(s), and various pin configuration
+  parameters, such as pull-up, slew rate, etc.
+
+  Each configuration node can consist of multiple nodes describing the pinmux and
+  pinconf options. Those nodes can be pinmux nodes or pinconf nodes.

 platform

Add Pinctrl support for Xilinx Versal platform.
Driver checks for firmware support to retrieve the Pin information, if it
is supported then proceed further otherwise it returns error saying
operation not supported. Latest Xilinx Platform Management Firmware must
be used to make use of the Pinctrl driver for Versal platform.

Subject: [PATCH 0134/2948] dt-bindings: pinctrl: Add SA8255p TLMM

Add compatible for TLMM block representing support on SA8255p.

SA8255p uses the same TLMM block as SA8775p however the ownership
of pins are split between Firmware VM and Linux VM on SA8255p. For
example, pins used by UART are owned and configured by Firmware VM
while pins used by ethernet are owned and configured by Linux VM.
Therefore, adding a sa8255p specific compatible to mark the difference.

Subject: [PATCH 0135/2948] ARM: imx: Allow user to disable pinctrl

Making pinctrl drivers and subsequently the pinctrl framework
user-controllable, allows building a kernel without this.
While in many (most) cases, this could make the system unbootable, it
does allow building smaller kernels for those situations where picntrl
is not needed.

One such situation is when building a kernel for NXP LS1021A systems,
which does not have run-time controllable pinctrl, so pinctrl framework
and drivers are 100% dead-weight.

Subject: [PATCH 0136/2948] pinctrl: freescale: Use CONFIG_SOC_IMXRT to guard
 i.MX RT1xxx drivers

This aligns with the use of SOC_IMX* as dependencies for all the other
mach-imx pinctrl drivers. Enabling i.MX RT pinctrl drivers for a kernel
with out i.MX RT SOC support is pointless.

+description: |
+  Pinmux and pinconf controller in the T-Head TH1520 RISC-V SoC.
+
+  The TH1520 has 3 groups of pads each controlled from different memory ranges.
+  Confusingly the memory ranges are named
+    PADCTRL_AOSYS  -> PAD Group 1
+    PADCTRL1_APSYS -> PAD Group 2
+    PADCTRL0_APSYS -> PAD Group 3
+
+  Each pad can be muxed individually to up to 6 different functions. For most
+  pads only a few of those 6 configurations are valid though, and a few pads in
+  group 1 does not support muxing at all.
+
+  Pinconf is fairly regular except for a few pads in group 1 that either can't
+  be configured or has some special functions. The rest have configurable drive
+  strength, input enable, schmitt trigger, slew rate, pull-up and pull-down in
+  addition to a special strong pull up.
+
+  Certain pads in group 1 can be muxed to AUDIO_PA0 - AUDIO_PA30 functions and
+  are then meant to be used by the audio co-processor. Each such pad can then
+  be further muxed to either audio GPIO or one of 4 functions such as UART, I2C
+  and I2S. If the audio pad is muxed to one of the 4 functions then pinconf is
+  also configured in different registers. All of this is done from a different
+  AUDIO_IOCTRL memory range and is left to the audio co-processor for now.

Subject: [PATCH 0145/2948] pinctrl: canaan: Add support for k230 SoC

Configuration of the K230 is similar to that of the K210. However, in
K210, the 256 functions for each pin are shared, whereas in K230,
multiplex functions are different for every pin.

`drv_data` of `pinctrl_pin_desc` is pointing to currently activated
group, which is used to print the name of current function of pin in
`pin_dbg_show` and will be updated in `set_mux`, so they are not set
const.

Subject: [PATCH 0146/2948] dt-bindings: pinctrl: amlogic,meson-pinctrl: lower
 gpio-line-names minItems for meson8b

The Amlogic Meson8b SoC has 83 CBUS GPIOs, thus lower the minItems
for gpio-line-names to account for it, fixing DTBs check on Meson8b
based boards.

Subject: [PATCH 0149/2948] pinctrl: aw9523: Drop explicit initialization of
 struct i2c_device_id::driver_data to 0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

Subject: [PATCH 0150/2948] pinctrl: sx150x: Use maple tree register cache

The sx150x driver uses a rbtree register cache with no obvious reason for
specifically preferring it. The maple tree register cache is based on a
more modern data structure and makes implementation decisions more suitable
for modern systems so let's switch the driver to use that. No functional
change.

Subject: [PATCH 0155/2948] pinctrl: rockchip: improve error message for
 incorrect rockchip,pins property

If one improperly writes a rockchip,pins property, the pinctrl driver
basically just states that one in the myriad of pinctrl nodes is
improper but does not tell you which one.

Instead, let's print the full name of the Device Tree node that is
improper as well as provide more context on what the expected content
is.

Note that this should be rather unnecessary if one reads the output of
the dtbs_check as it would be highlighted as an error.

Subject: [PATCH 0156/2948] dt-bindings: PCI: mediatek-gen3: Allow exact number
 of clocks only

In MediaTek PCIe gen3 bindings, "clocks" accepts a range of 1-6 clocks
across all SoCs. But in practice, each SoC requires a particular number of
clocks as defined in "clock-names", and the length of "clocks" and
"clock-names" can be inconsistent with current bindings.

For example:

  - MT8188, MT8192 and MT8195 all require 6 clocks, while the bindings
    accept 4-6 clocks.

  - MT7986 requires 4 clocks, while the bindings accept 4-6 clocks.

Update minItems and maxItems properties for individual SoCs as needed to
only accept the correct number of clocks.

From f69767a1ada3ac74be2e1ac0795a05e1d1384eff Mon Sep 17 00:00:00 2001
From: Wei Huang <wei.huang2@amd.com>
Date: Wed, 2 Oct 2024 11:59:50 -0500
Subject: [PATCH 0158/2948] PCI: Add TLP Processing Hints (TPH) support

Add support for PCIe TLP Processing Hints (TPH) support (see PCIe r6.2,
sec 6.17).

Add TPH register definitions in pci_regs.h, including the TPH Requester
capability register, TPH Requester control register, TPH Completer
capability, and the ST fields of MSI-X entry.

Introduce pcie_enable_tph() and pcie_disable_tph(), enabling drivers to
toggle TPH support and configure specific ST mode as needed. Also add a new
kernel parameter, "pci=notph", allowing users to disable TPH support across
the entire system.

From d2e8a34876ce69b27f450eebfc550ab8e316f752 Mon Sep 17 00:00:00 2001
From: Wei Huang <wei.huang2@amd.com>
Date: Wed, 2 Oct 2024 11:59:51 -0500
Subject: [PATCH 0159/2948] PCI/TPH: Add Steering Tag support

Add pcie_tph_get_cpu_st() to allow a caller to retrieve Steering Tags for a
target memory associated with a specific CPU. The ST tag is retrieved by
invoking PCI ACPI "_DSM to Query Cache Locality TPH Features" method
(rev=0x7, func=0xF) of the device's Root Port device.

Add pcie_tph_set_st_entry() to update the device's Steering Tags. The tags
will be written into the device's MSI-X table or the ST table located in
the TPH Extended Capability space.

Subject: [PATCH 0160/2948] PCI: Fix reset_method_store() memory leak

In reset_method_store(), a string is allocated via kstrndup() and assigned
to the local "options". options is then used in with strsep() to find
spaces:

  while ((name = strsep(&options, " ")) != NULL) {

If there are no remaining spaces, then options is set to NULL by strsep(),
so the subsequent kfree(options) doesn't free the memory allocated via
kstrndup().

Fix by using a separate tmp_options to iterate with strsep() so options is
preserved.

Subject: [PATCH 0161/2948] perf jevents: Don't stop at the first matched pmu
 when searching a events table

The "perf all PMU test" fails on a Coffee Lake machine.

The failure is caused by the below change in the commit e2641db83f18
("perf vendor events: Add/update skylake events/metrics").

+    {
+        "BriefDescription": "This 48-bit fixed counter counts the UCLK cycles",
+        "Counter": "FIXED",
+        "EventCode": "0xff",
+        "EventName": "UNC_CLOCK.SOCKET",
+        "PerPkg": "1",
+        "PublicDescription": "This 48-bit fixed counter counts the UCLK cycles.",
+        "Unit": "cbox_0"
     }

The other cbox events have the unit name "CBOX", while the fixed counter
has a unit name "cbox_0". So the events_table will maintain separate
entries for cbox and cbox_0.

The perf_pmus__print_pmu_events() calculates the total number of events,
allocate an aliases buffer, store all the events into the buffer, sort,
and print all the aliases one by one.

The problem is that the calculated total number of events doesn't match
the stored events in the aliases buffer.

The perf_pmu__num_events() is used to calculate the number of events. It
invokes the pmu_events_table__num_events() to go through the entire
events_table to find all events. Because of the
pmu_uncore_alias_match(), the suffix of uncore PMU will be ignored. So
the events for cbox and cbox_0 are all counted.

When storing events into the aliases buffer, the
perf_pmu__for_each_event() only process the events for cbox.

Since a bigger buffer was allocated, the last entry are all 0.
When printing all the aliases, null will be outputted, and trigger the
failure.

The mismatch was introduced from the commit e3edd6cf6399 ("perf
pmu-events: Reduce processed events by passing PMU"). The
pmu_events_table__for_each_event() stops immediately once a pmu is set.
But for uncore, especially this case, the method is wrong and mismatch
what perf does in the perf_pmu__num_events().

With the patch,
$ perf list pmu | grep -A 1 clock.socket
   unc_clock.socket
        [This 48-bit fixed counter counts the UCLK cycles. Unit: uncore_cbox_0
$ perf test "perf all PMU test"
  107: perf all PMU test                                               : Ok

Subject: [PATCH 0166/2948] tools/perf: Correctly calculate sample period for
 inherited SAMPLE_READ values

Sample period calculation in deliver_sample_value is updated to
calculate the per-thread period delta for events that are inherit +
PERF_SAMPLE_READ. When the sampling event has this configuration, the
read_format.id is used with the tid from the sample to lookup the
storage of the previously accumulated counter total before calculating
the delta. All existing valid configurations where read_format.value
represents some global value continue to use just the read_format.id to
locate the storage of the previously accumulated total.

perf_sample_id is modified to support tracking per-thread
values, along with the existing global per-id values. In the
per-thread case, values are stored in a hash by tid within the
perf_sample_id, and are dynamically allocated as the number is not known
ahead of time.

Subject: [PATCH 0167/2948] tools/perf: Allow inherit + PERF_SAMPLE_READ when
 opening events

The "perf record" tool will now default to this new mode if the user
specifies a sampling group when not in system-wide mode, and when
"--no-inherit" is not specified.

This change updates evsel to allow the combination of inherit
and PERF_SAMPLE_READ.

A fallback is implemented for kernel versions where this feature is not
supported.

 #

The root cause is a new stack layout, two functions have been added
as seen below.

 # perf script | tac | grep -m1 '^ping' -B9 | tac

 #

The new functions in the call chain are:
 - text_to_binary_address()
 - gaih_inet().

Both functions are inlined and do not show up in the output
of the nm command:

  # nm -a /usr/lib64/libc.so.6 | \
	grep -E '(text_to_binary_address|gaih_inet)$'
  #

There is no possibility to add these 2 functions depending on their
existance in the C library.

Add text_to_binary_address() and gaih_inet() to the list of
expected functions in an compatible way and extend the regular
expression. On s390 the backtrace can now be

   Before                   After
   probe_libc:inet_pton     probe_libc:inet_pton
   inet_pton		    inet_pton
   getaddrinfo		    getaddrinfo | text_to_binary_address
   main			    main | gaih_inet

Output after:
 # perf test -F 86
 86: probe libc's inet_pton & backtrace it with ping  : Ok

Subject: [PATCH 0169/2948] perf trace: Keep exited threads for summary

Since 9ffa6c7512ca ("perf machine thread: Remove exited threads by
default") perf cleans exited threads up, but as said, sometimes they
are necessary to be kept. The mentioned commit does not cover all the
cases, we also need the information to construct the summary table in
perf-trace.

Before:
    # perf trace -s true

     Summary of events:

After:
    # perf trace -s -- true

     Summary of events:

Subject: [PATCH 0176/2948] soundwire: mipi_disco: add MIPI-specific
 property_read_bool() helpers

The existing device/fwnode_property_read_bool() helpers only check if
the property is present.

The MIPI DisCo for SoundWire specification allows properties to be
exposed with a value of 'false'. Using the standard helpers to
retrieve the MIPI-defined properties causes all kinds of logical
inversions leading to loss of functionality - such as jack detection
in clock-stop mode broken when the device properties are read in
Realtek codec drivers.

This patch adds new MIPI/SoundWire helpers which first check if the
property is present, and then return the actual value extracted from
platform firmware.

Modifying the default property handling was considered as a possible
solution, but it could lead to other types of logical inversions
breaking 'working' setups. Andy Shevchenko also pointed out that DT
keeps values in the BE32 format, it's probably best to avoid
endianness complications.

The path of least resistance was chosen, with MIPI-specific helpers
which can be tested and with no side effects outside of the SoundWire
subsystem.

Subject: [PATCH 0179/2948] soundwire: optimize sdw_bus structure

The sdw_bus structure has seen multiple additions over the years. It's
one of the most used structures in this subsystem, so there's merit in
reshuffling the members a bit with 'pahole' to reduce holes and
structures across cache lines.

before:

struct sdw_bus {
	struct device *            dev;                  /*     0     8 */
	struct sdw_master_device * md;                   /*     8     8 */
	int                        controller_id;        /*    16     4 */
	unsigned int               link_id;              /*    20     4 */
	int                        id;                   /*    24     4 */

	/* XXX 4 bytes hole, try to pack */

	struct list_head           slaves;               /*    32    16 */
	long unsigned int          assigned[1];          /*    48     8 */
	struct mutex               bus_lock;             /*    56   160 */

Subject: [PATCH 0183/2948] soundwire: mipi-disco: remove DPn audio-modes

The concept of DPn audio-modes was never used by anyone, and was
removed from the DisCo for SoundWire 2.0 specification.

Remove the definitions and TODO.

Subject: [PATCH 0184/2948] soundwire: mipi-disco: add error handling for
 property array read

The existing code assumes that there are no possible errors when using
fwnode_property_read_u32_array(), because fwnode_property_count_u32()
reads this array to determine its number of elements. We need to also
protect the second read to be completely bullet-proof.

Subject: [PATCH 0188/2948] soundwire: mipi-disco: add new properties from 2.0
 spec

The DisCo for SoundWire 2.0 spec adds support for new
'mipi-sdw-sdca-interrupt-register-list' and
'mipi-sdw-commit-register-supported'.

This patch only adds the definitions and property reads, but the use
of these properties will come at some point in the future when needed.

Note a slight conceptual disconnect between the MIPI DisCo definition
of a boolean property and the Linux implementation. The latter only
checks the presence of the property to set its value to 'true',
whereas the MIPI definitions allow for a property with a 'false'
value. This patch uses the new introduced mipi_device_property_read_bool()
to handle it.

Subject: [PATCH 0189/2948] soundwire: mipi-disco: add support for DP0/DPn
 'lane-list' property

The SoundWire specification did not clearly require that ports could
use all Lanes. Some SoundWire/SDCA peripheral adopters added
restrictions on which lanes can be used by what port, and the DisCo
for SoundWire 2.1 specification added a 'lane-list' property to model
this hardware limitation.

When not specified, the ports can use all Lanes. Otherwise, the
'lane-list' indicates which Lanes can be used, sorted by order of
preference (most-preferred-first).

This patch only reads the properties, the use of this property will
come at a later time with multi-lane support.

Subject: [PATCH 0200/2948] Input: ipaq-micro-keys - use guard notation when
 acquiring mutex and spinlock

This makes the code more compact and error handling more robust
by ensuring that locks are released in all code paths when control

Subject: [PATCH 0208/2948] Input: st-keyscan - use guard notation when
 acquiring mutex

This makes the code more compact and error handling more robust
by ensuring that mutexes are released in all code paths when control
leaves critical section.

Using guard notation makes the code more compact and error handling
more robust by ensuring that mutexes are released in all code paths
when control leaves critical section.

Subject: [PATCH 0213/2948] Input: turbografx - use guard notation when
 acquiring mutex

Using guard notation makes the code more compact and error handling
more robust by ensuring that mutexes are released in all code paths
when control leaves critical section.

Subject: [PATCH 0217/2948] Input: cm109 - use guard notation when acquiring
 mutex and spinlock

Using guard notation makes the code more compact and error handling
more robust by ensuring that locks are released in all code paths
when control leaves critical section.

Subject: [PATCH 0222/2948] Input: drv2665 - use guard notation when acquiring
 mutex

Using guard notation makes the code more compact and error handling
more robust by ensuring that mutexes are released in all code paths
when control leaves critical section.

Subject: [PATCH 0237/2948] perf test: Restore sample rate for perf_event_attr

Test "Setup struct perf_event_attr" consists of multiple test cases that
can affect the max sample rate value for perf events. Some test cases
check this value as it should not be lowered under the set minimum for
the given test. Currently, it is possible for the test cases to affect
each other as the previous tests can lower the sample rate, leading to
a possible failure of some of the future test cases as the value is not
restored at any point.

   # 10: Setup struct perf_event_attr:
    --- start ---
    test child forked, pid 104220
    Using CPUID 0x00000000413fd0c1
    running './tests/attr/test-record-C0'
    Current sample rate: 10000
    running './tests/attr/test-record-basic'
    Current sample rate: 900
    running './tests/attr/test-record-branch-any'
    Current sample rate: 600
    running './tests/attr/test-record-dummy-C0'
    Current sample rate: 600
    expected sample_period=4000, got 600
    FAILED './tests/attr/test-record-dummy-C0' - match failure

Restore the max sample rate value for perf events to a reasonable value
before each test case if its value was lowered too much to ensure the
same conditions for each test case.

There is a difference between the SYNOPSIS section of the help message
and the man page (tools/perf/Documentation/perf-list.txt) for the perf
list command. After checking, we found that the help message reflected
the latest specifications. Therefore, revised the SYNOPSIS section of
the man page to match the help message.

Subject: [PATCH 0239/2948] PCI: controller: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return
void") .remove() is (again) the right callback to implement for platform
drivers.

Convert all PCI controller drivers to use .remove(), with the eventual goal
to drop struct platform_driver::remove_new(). As .remove() and .remove_new()
have the same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

Subject: [PATCH 0240/2948] PCI: acpiphp_ampere_altra: Switch back to struct
 platform_driver::remove()

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return
void") .remove() is (again) the right callback to implement for platform
drivers.

Convert all PCI controller drivers to use .remove(), with the eventual goal
to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just changing
the structure member name in the driver initializer.

Subject: [PATCH 0241/2948] perf arm-spe: Define metadata header version 2

The first version's metadata header structure doesn't include a field to
indicate a header version, which is not friendly for extension.

Define the metadata version 2 format with a new header structure and
extend per CPU's metadata. In the meantime, the old metadata header will
still be supported for backward compatibility.

Subject: [PATCH 0242/2948] perf arm-spe: Calculate meta data size

The metadata is designed to contain a header and per CPU information.

The arm_spe_find_cpus() function is introduced to identify how many CPUs
support ARM SPE. Based on the CPU number, calculates the metadata size.

Subject: [PATCH 0244/2948] perf arm-spe: Support metadata version 2

This commit is to support metadata version 2 and at the meantime it is
backward compatible for version 1's format.

The metadata version 1 doesn't include the ARM_SPE_HEADER_VERSION field.
As version 1 is fixed with two u64 fields, by checking the metadata
size, it distinguishes the metadata is version 1 or version 2 (and any
new versions if later will have). For version 2, it reads out CPU number
and retrieves the metadata info for every CPU.

Subject: [PATCH 0246/2948] perf test attr: Add back missing topdown events

With the patch 0b6c5371c03c "Add missing topdown metrics events" eight
topdown metric events with numbers ranging from 0x8000 to 0x8700 were
added to the test since they were added as 'perf stat' default events.
Later the patch 951efb9976ce "Update no event/metric expectations" kept
only 4 of those events(0x8000-0x8300).

Currently, the topdown events with numbers 0x8400 to 0x8700 are missing
from the list of expected events resulting in a failure. Add back the
missing topdown events.

Fixes: 951efb9976ce ("perf test attr: Update no event/metric expectations")

Subject: [PATCH 0250/2948] scsi: ufs: core: Make ufshcd_uic_cmd_compl() easier
 to analyze

In ufshcd_uic_cmd_compl(), there is code that dereferences 'cmd' with
and without checking the 'cmd' pointer. This confuses static source code
analyzers like Coverity and sparse. Since none of the code in
ufshcd_uic_cmd_compl() can do anything useful if 'cmd' is NULL, move the
'cmd' test near the start of this function.

Subject: [PATCH 0251/2948] scsi: ufs: core: Always initialize the UIC done
 completion

Simplify __ufshcd_send_uic_cmd() by always initializing the
uic_cmd::done completion. This is fine since the time required to
initialize a completion is small compared to the time required to
process an UIC command.

Subject: [PATCH 0258/2948] scsi: ufs: core: Zero utp_upiu_req at the beginning

This patch introduces a previously missing step: zeroing the 'utp_upiu_req'
structure at the beginning of each upiu transaction. This ensures that the
upiu request fields are properly initialized, preventing potential issues

While at it, re-use some of the common initializations for query and
command upiu.

Subject: [PATCH 0259/2948] scsi: ufs: ufs-qcom: Add fixup_dev_quirks vops

Add fixup_dev_quirk vops in QCOM UFS platforms and provide an initial
vendor-specific device quirk table to add UFS device specific quirks which
are enabled only for specified UFS devices.

 - Add DELAY_BEFORE_LPM quirk for Skhynix UFS devices to introduce a delay
   before VCC is powered off in QCOM platforms.

 - Add DELAY_AFTER_LPM quirk for Toshiba UFS devices to introduce a delay
   after the VCC power rail is turned off in QCOM platforms.

 - Move UFS_DEVICE_QUIRK_HOST_PA_TACTIVATE quirk from
   ufs_qcom_apply_dev_quirks to ufs_qcom_dev_fixups.

The "PC" define is colliding with the (apparently broadcased)
define for "program counter" on Loongarch, so let's rename all
these 2-letter defines so they don't collide with stuff.

Fixes: a55222b7a132 ("pinctrl: freescale: enable use with COMPILE_TEST")

Subject: [PATCH 0264/2948] Input: serio - define serio_pause_rx guard to pause
 and resume serio ports

serio_pause_rx() and serio_continue_rx() are usually used together to
temporarily stop receiving interrupts/data for a given serio port.
Define "serio_pause_rx" guard for this so that the port is always
resumed once critical section is over.

Example:

	scoped_guard(serio_pause_rx, elo->serio) {
		elo->expected_packet = toupper(packet[0]);
		init_completion(&elo->cmd_done);
	}

Subject: [PATCH 0265/2948] Input: libps2 - use guard notation when temporarily
 pausing serio ports

Using guard notation makes the code more compact and error handling
more robust by ensuring that serio ports are resumed in all code paths
when control leaves critical section.

Subject: [PATCH 0274/2948] Input: hyperv-keyboard - use guard notation when
 acquiring spinlock

Using guard notation makes the code more compact and error handling
more robust by ensuring that locks are released in all code paths
when control leaves critical section.

Subject: [PATCH 0283/2948] Input: serio_raw - use guard notation for locks and
 other resources

Use guard notation when acquiring mutexes and spinlocks, and when
pausing and resuming serio port. Such guard notation makes the code
more compact and error handling more robust by ensuring that locks
are released in all code paths when control leaves critical section.

Subject: [PATCH 0284/2948] Input: serio-raw - fix potential serio port name
 truncation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When compiling with W=1 the following warnings are triggered:

drivers/input/serio/serio_raw.c: In function ‘serio_raw_connect’:
drivers/input/serio/serio_raw.c:303:28: error: ‘%ld’ directive output may be truncated writing between 1 and 11 bytes into a region of size 7 [-Werror=format-truncation=]
  303 |                  "serio_raw%ld", (long)atomic_inc_return(&serio_raw_no));

atomic_inc_return() returns an int, so there is no reason to cast it
to long and print as such. Fix the issue by removing the cast,
printing it as unsigned decimal, and expanding the name from 16 to 20
bytes to accommodate the largest possible port number.

Subject: [PATCH 0287/2948] Input: xilinx_ps2 - use guard notation when
 acquiring spinlock

Using guard notation makes the code more compact and error handling
more robust by ensuring that locks are released in all code paths
when control leaves critical section.

Use the scoped variant of `device_for_each_child_node()` to
automatically handle early exits.

This prevents memory leaks if new error paths are introduced,
as no explicit refcount decrement via `fwnode_handle_put()` is needed.

The function strcpy() is depreciated and potentially unsafe. It performs
no bounds checking on the destination buffer. This could result in
linear overflows beyond the end of the buffer, leading to all kinds of
misbehaviors. The safe replacement is strscpy() [1].

this fixes checkpatch warning:

Subject: [PATCH 0298/2948] dt-bindings: usb: genesys,gl850g: allow downstream
 device subnodes

As this binding describes USB hubs, it's natural for them to have
downstream devices.

Change "additionalProperties" to "unevaluatedProperties" to allow
properties defined in usb-device.yaml (for DT cells properties) and add
a pattern-based downstream device subnode rule to match those subnodes.

These changes allow downstream devices get defined under the hub.

Subject: [PATCH 0299/2948] usb: phy: isp1301:: Drop explicit initialization of
 struct i2c_device_id::driver_data to 0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

Subject: [PATCH 0300/2948] usb: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/usb to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

Subject: [PATCH 0301/2948] dt-bindings: usb: cypress,cypd4226: Drop Tegra
 specific GPIO defines

The Tegra GPIO define is a problem for the magic code which extracts
the examples and fixes up the interrupt provider. This was partially
worked around by putting #interrupt-cells in the parent. However,
that's incomplete and causes a warning when dtc "interrupt_provider"
check is enabled. Just drop the Tegra specific define and simplify
the example.

Subject: [PATCH 0302/2948] usb: chipidea: add CI_HDRC_HAS_SHORT_PKT_LIMIT flag

Currently, the imx deivice controller has below limitations:

1. can't generate short packet interrupt if IOC not set in dTD. So if one
   request span more than one dTDs and only the last dTD set IOC, the usb
   request will pending there if no more data comes.
2. the controller can't accurately deliver data to differtent usb requests
   in some cases due to short packet. For example: one usb request span 3
   dTDs, then if the controller received a short packet the next packet
   will go to 2nd dTD of current request rather than the first dTD of next
   request.
3. can't build a bus packet use multiple dTDs. For example: controller
   needs to send one packet of 512 bytes use dTD1 (200 bytes) + dTD2
   (312 bytes), actually the host side will see 200 bytes short packet.

Based on these limits, add CI_HDRC_HAS_SHORT_PKT_LIMIT flag and use it on
imx platforms.

Subject: [PATCH 0303/2948] usb: chipidea: udc: limit usb request length to max
 16KB

To let the device controller work properly on short packet limitations,
one usb request should only correspond to one dTD. Then every dTD will
set IOC. In theory, each dTD support up to 20KB data transfer if the
offset is 0. Due to we cannot predetermine the offset, this will limit
the usb request length to max 16KB. This should be fine since most of
the user transfer data based on this size policy.

Subject: [PATCH 0304/2948] usb: chipidea: udc: create bounce buffer for
 problem sglist entries if possible

The chipidea controller doesn't fully support sglist, such as it can not
transfer data spanned more dTDs to form a bus packet, so it can only work
on very limited cases.

The limitations as below:
1. the end address of the first sg buffer must be 4KB aligned.
2. the start and end address of the middle sg buffer must be 4KB aligned.
3. the start address of the first sg buffer must be 4KB aligned.

However, not all the use cases violate these limitations. To make the
controller compatible with most of the cases, this will try to bounce the
problem sglist entries which can be found by sglist_get_invalid_entry().
Then a bounced line buffer (the size will roundup to page size) will be
allocated to replace the remaining problem sg entries. The data will be
copied between problem sg entries and bounce buffer according to the
transfer direction. The bounce buffer will be freed when the request
completed.

Subject: [PATCH 0305/2948] usb: chipidea: udc: handle USB Error Interrupt if
 IOC not set

As per USBSTS register description about UEI:

  When completion of a USB transaction results in an error condition, this
  bit is set by the Host/Device Controller. This bit is set along with the
  USBINT bit, if the TD on which the error interrupt occurred also had its
  interrupt on complete (IOC) bit set.

UI is set only when IOC set. Add checking UEI to fix miss call
isr_tr_complete_handler() when IOC have not set and transfer error happen.

Currently, ATDTW semaphore is used to safety link new dTD to dQH. But this
code has a bug when the endpoint is already in error before polling ATDTW
or just met error during polling ATDTW. In that cases, ATDTW will never
turn to 1 and the cpu will busy loop there.

When the endpoint met error, ENDPTSTAT will be cleared by HW. Therefore,
ENDPTSTAT should also be considered during this process. In case of
endpoint error, the current dTD should not be pushed to the head of dQH
since some dTDs may be still not executed. Therefore, the link logic is
also improved accordingly.

Impove device mode ISO transfer error tolerant by reprime the corresponding

The recovery steps when error occurs:
- Delete the error dTD from dQH and giveback request to user.
- Do reprime if dQH is not empty.
- Do prime when new dTD is queued if dQH is empty

Subject: [PATCH 0311/2948] usb: using mutex lock and supporting O_NONBLOCK
 flag in iowarrior_read()

iowarrior_read() uses the iowarrior dev structure, but does not use any
lock on the structure. This can cause various bugs including data-races,
so it is more appropriate to use a mutex lock to safely protect the
iowarrior dev structure. When using a mutex lock, you should split the
branch to prevent blocking when the O_NONBLOCK flag is set.

In addition, it is unnecessary to check for NULL on the iowarrior dev
structure obtained by reading file->private_data. Therefore, it is
better to remove the check.

Subject: [PATCH 0313/2948] USB: chaoskey: fail open after removal

chaoskey_open() takes the lock only to increase the
counter of openings. That means that the mutual exclusion
with chaoskey_disconnect() cannot prevent an increase
of the counter and chaoskey_open() returning a success.

If that race is hit, chaoskey_disconnect() will happily
free all resources associated with the device after
it has dropped the lock, as it has read the counter
as zero.

To prevent this race chaoskey_open() has to check
the presence of the device under the lock.
However, the current per device lock cannot be used,
because it is a part of the data structure to be
freed. Hence an additional global mutex is needed.
The issue is as old as the driver.

compatible "fsl,imx95-usb-phy" for i.MX95. Also change reg maxItems
to 2 since i.MX95 needs another regmap to control Type-C Assist (TCA)
block. Since i.MX95 usb phy is able to switch SS lanes, this will also
add orientation-switch and port property to the file.

Simplify pci_create_slot() by splitting an "if" statement into two parts.
In order to not duplicate error handling, add a new label to handle kobj
put.

Subject: [PATCH 0317/2948] iio: adc: ad7606: add support for AD7606C-{16,18}
 parts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The AD7606C-16 and AD7606C-18 are pretty similar with the AD7606B.
The main difference between AD7606C-16 & AD7606C-18 is the precision in
bits (16 vs 18).
Because of that, some scales need to be defined for the 18-bit variants, as
they need to be computed against 2**18 (vs 2**16 for the 16 bit-variants).

Because the AD7606C-16,18 also supports bipolar & differential channels,
for SW-mode, the default range of 10 V or ±10V should be set at probe.
On reset, the default range (in the registers) is set to value 0x3 which
corresponds to '±10 V single-ended range', regardless of bipolar or
differential configuration.

Aside from the scale/ranges, the AD7606C-16 is similar to the AD7606B.

The AD7606C-18 variant offers 18-bit precision. Because of this, the
requirement to use this chip is that the SPI controller supports padding
of 18-bit sequences to 32-bit arrays.

Subject: [PATCH 0321/2948] iio: light: ltr390: Suspend and Resume support

Added support for suspend and resume PM ops.
We suspend the sensor by clearing the ALS_UVS_EN bit in the MAIN CONTROL
register. And we resume it by setting that bit.

Subject: [PATCH 0322/2948] iio: light: ltr390: Interrupts and threshold event
 support

Added support for threshold events for both the ALS and UVI channels.
The events are reported when the threshold interrupt is triggered. Both
rising and falling threshold types are supported.

Subject: [PATCH 0323/2948] iio: light: ltr390: Add interrupt persistance
 support

Added support to configure the threshold interrupt persistance value by
providing IIO_EV_INFO_PERIOD attribute. The value written to the
attribute should be in miliseconds and should be greater than the
sampling rate of the sensor.

Subject: [PATCH 0325/2948] iio: adc: ti-ads1119: Drop explicit initialization
 of struct i2c_device_id::driver_data to 0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

Subject: [PATCH 0326/2948] iio: adc: qcom-pm8xxx-xoadc: use scoped
 device_for_each_child_node()

Switch to device_for_each_child_node_scoped() to simplify the code by
removing the need for calls to fwnode_handle_put() in the error path.

This prevents possible memory leaks if new error paths are added without
the required call to fwnode_handle_put().

 adc5_get_fw_data() error messages

In the event that no channels (child nodes) are defined, the adc5 driver
will provide a generic error message indicating that adc5_get_fw_data()
returned -EINVAL. In all other error cases we get two error messages,
one helpful and the generic one.

Add a specific error message for the no channels case, and drop the
generic one, in order to improve the generates log prints in both cases.

Subject: [PATCH 0347/2948] riscv: Enable cbo.zero only when all harts support
 Zicboz

Currently, we enable cbo.zero for usermode on each hart that supports
the Zicboz extension. This means that the [ms]envcfg CSR value may
differ between harts. Other features, such as pointer masking and CFI,
require setting [ms]envcfg bits on a per-thread basis. The combination
of these two adds quite some complexity and overhead to context
switching, as we would need to maintain two separate masks for the
per-hart and per-thread bits. Andrew Jones, who originally added Zicboz
support, writes[1][2]:

  I've approached Zicboz the same way I would approach all
  extensions, which is to be per-hart. I'm not currently aware of
  a platform that is / will be composed of harts where some have
  Zicboz and others don't, but there's nothing stopping a platform
  like that from being built.

  So, how about we add code that confirms Zicboz is on all harts.
  If any hart does not have it, then we complain loudly and disable
  it on all the other harts. If it was just a hardware description
  bug, then it'll get fixed. If there's actually a platform which
  doesn't have Zicboz on all harts, then, when the issue is reported,
  we can decide to not support it, support it with defconfig, or
  support it under a Kconfig guard which must be enabled by the user.

Let's follow his suggested solution and require the extension to be
available on all harts, so the envcfg CSR value does not need to change
when a thread migrates between harts. Since we are doing this for all
extensions with fields in envcfg, the CSR itself only needs to be saved/
restored when it is present on all harts.

This should not be a regression as no known hardware has asymmetric
Zicboz support, but if anyone reports seeing the warning, we will
re-evaluate our solution.

Subject: [PATCH 0348/2948] riscv: Add support for per-thread envcfg CSR values

Some bits in the [ms]envcfg CSR, such as the CFI state and pointer
masking mode, need to be controlled on a per-thread basis. Support this
by keeping a copy of the CSR value in struct thread_struct and writing
it during context switches. It is safe to discard the old CSR value
during the context switch because the CSR is modified only by software,
so the CSR will remain in sync with the copy in thread_struct.

Use ALTERNATIVE directly instead of riscv_has_extension_unlikely() to
minimize branchiness in the context switching code.

Since thread_struct is copied during fork(), setting the value for the
init task sets the default value for all other threads.

Subject: [PATCH 0349/2948] riscv: Call riscv_user_isa_enable() only on the
 boot hart

Now that the [ms]envcfg CSR value is maintained per thread, not per
hart, riscv_user_isa_enable() only needs to be called once during boot,
to set the value for the init task. This also allows it to be marked as
__init.

Subject: [PATCH 0360/2948] iio: pressure: bmp280: Use char instead of s32 for
 data buffer

As it was reported and discussed here [1], storing the sensor data in an
endian aware s32 buffer is not optimal. Advertising the timestamp as an
addition of 2 s32 variables which is also implied is again not the best
practice. For that reason, change the s32 sensor_data buffer to a u8
buffer and align it properly.

Subject: [PATCH 0361/2948] iio: light: veml6030: add set up delay after any
 power on sequence

The veml6030 requires a delay of 4 ms after activating the sensor. That
is done correctly during the hw initialization, but it's missing after
resuming.

Move the delay to the power on function to make sure that it is always
observerd. When at it, use fsleep() instead of usleep_range() as such a
narrow range is not required.

Drop custom attributes by using the standard read_avail() callback to
read scale and integration time. When at it, add the integration time
and scale attributes fro the WHITE channel, as they modify its value as
well. To avoid breaking the current ABI, these attributes must be kept
as separate for both channels even though they are shared under the
hood.

Subject: [PATCH 0366/2948] iio: light: veml6030: drop processed info for white
 channel

The resolution of the WHITE channel is not provided by the manufacturer,
neither in the datasheet nor in the application note (even their
proprietary application only processes the ALS channel, giving raw
values for WHITE).

The current implementation assumes that both resolutions are identical,
which is extremely unlikely, especially for photodiodes with different
spectral responses.

Drop the processed information as it is meaningless.

 error paths

Move devm_add_action_or_reset() with a device shut down action to the
hardware initialization function to ensure that any error path after
powering on the device leads to a power off. Add struct device *dev
to the argument list to clarify the device the action is registered
against, and use it wherever &client->dev was used.

The veml6035 is a similar ambient light sensor to the veml6030, and
from the bindings point of view, it shares the same properties. Its
only difference in that respect is a different I2C address.

Estend the existing bindings to support the veml6035 ALS.

Subject: [PATCH 0369/2948] iio: light: veml6030: add support for veml6035

The veml6035 is an ALS that shares most of its functionality with the
veml6030, which allows for some code recycling.

Some chip-specific properties differ and dedicated functions to get and
set the sensor gain as well as its initialization are required.

Subject: [PATCH 0370/2948] phy: usb: update Broadcom driver table to use
 designated initializers

The Broadcom USB PHY driver contains a lookup table
(`reg_bits_map_tables`) to resolve register bitmaps unique to certain
versions of the USB PHY as found in various Broadcom chip families.
Historically, this table was just kept carefully in sync with the
"selector" enum every time the latter changed to ensure consistency.
However, a recent commit [1] introduced two new enumerators but did not
adjust the array for BCM4908, thus breaking the xHCI controller (and
boot process) on this platform and revealing the fragility of this
approach.

Since these arrays are a little sparse (many elements are zero) and the
position of the array elements is significant only insofar as they agree
with the enumerators, designated initializers are a better fit than
positional initializers here. Convert this table accordingly.

Subject: [PATCH 0371/2948] phy: phy-rockchip-inno-usb2: Perform trivial code
 cleanups

Perform a few trivial code cleanups, e.g. to obey the reverse Christmas tree
rule, to avoid use of "{ ... }" code blocks where they aren't really needed,
or to avoid line wrapping by using the 100-column width better.

No intended functional changes are introduced by these code cleanups.

 allocation better

Return the actual error code upon failure to allocate extcon device, instead
of hardcoding -ENOMEM.  Use dev_err_probe() to also log appropriate messages,
which is fine because the containing function is used in the probe path.

CP11x UTMI PHY supports swapping D+/D- signals via digital control
register 1.

Add support for the "swap-dx-lanes" device-tree property, which lists
the port-ids that should swap D+ and D-.
The property is evaluated in probe and applied before power-on
during mvebu_cp110_utmi_port_setup.

Subject: [PATCH 0381/2948] rust: workqueue: remove unneeded
 ``#[allow(clippy::new_ret_no_self)]`

Perform the same clean commit b2516f7af9d2 ("rust: kernel: remove
`#[allow(clippy::new_ret_no_self)]`") did for a case that appeared in
workqueue in parallel in commit 7324b88975c5 ("rust: workqueue: add
helper for defining work_struct fields"):

    Clippy triggered a false positive on its `new_ret_no_self` lint
    when using the `pin_init!` macro. Since Rust 1.67.0, that does
    not happen anymore, since Clippy learnt to not warn about
    `-> impl Trait<Self>` [1][2].

    The kernel nowadays uses Rust 1.72.1, thus remove the `#[allow]`.

Subject: [PATCH 0383/2948] rust: types: avoid repetition in `{As,From}Bytes`
 impls

In order to provide `// SAFETY` comments for every `unsafe impl`, we would
need to repeat them, which is not very useful and would be harder to read.

We could perhaps allow the lint (ideally within a small module), but we
can take the chance to avoid the repetition of the `impl`s themselves
too by using a small local macro, like in other places where we have
had to do this sort of thing.

Thus add the straightforward `impl_{from,as}bytes!` macros and use them
to implement `FromBytes`.

This, in turn, will allow us in the next patch to place a `// SAFETY`
comment that defers to the actual invocation of the macro.

Subject: [PATCH 0384/2948] rust: enable `clippy::undocumented_unsafe_blocks`
 lint

Checking that we are not missing any `// SAFETY` comments in our `unsafe`
blocks is something we have wanted to do for a long time, as well as
cleaning up the remaining cases that were not documented [1].

Back when Rust for Linux started, this was something that could have
been done via a script, like Rust's `tidy`. Soon after, in Rust 1.58.0,
Clippy implemented the `undocumented_unsafe_blocks` lint [2].

Even though the lint has a few false positives, e.g. in some cases where
attributes appear between the comment and the `unsafe` block [3], there
are workarounds and the lint seems quite usable already.

Thus enable the lint now.

We still have a few cases to clean up, so just allow those for the moment
by writing a `TODO` comment -- some of those may be good candidates for
new contributors.

Subject: [PATCH 0385/2948] rust: enable `clippy::unnecessary_safety_comment`
 lint

In Rust 1.67.0, Clippy added the `unnecessary_safety_comment` lint [1],
which is the "inverse" of `undocumented_unsafe_blocks`: it finds places
where safe code has a `// SAFETY` comment attached.

The lint currently finds 3 places where we had such mistakes, thus it
seems already quite useful.

Thus clean those and enable it.

Subject: [PATCH 0386/2948] rust: enable `clippy::unnecessary_safety_doc` lint

In Rust 1.67.0, Clippy added the `unnecessary_safety_doc` lint [1],
which is similar to `unnecessary_safety_comment`, but for `# Safety`
sections, i.e. safety preconditions in the documentation.

This is something that should not happen with our coding guidelines in
mind. Thus enable the lint to have it machine-checked.

In Rust 1.73.0, Clippy introduced the `ignored_unit_patterns` lint [1]:

> Matching with `()` explicitly instead of `_` outlines the fact that
> the pattern contains no data. Also it would detect a type change
> that `_` would ignore.

There is only a single case that requires a change:

    error: matching over `()` is more explicit
       --> rust/kernel/types.rs:176:45
        |
    176 |         ScopeGuard::new_with_data((), move |_| cleanup())
        |                                             ^ help: use `()` instead of `_`: `()`
        |
        = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#ignored_unit_patterns
        = note: requested on the command line with `-D clippy::ignored-unit-patterns`

Thus clean it up and enable the lint -- no functional change intended.

Subject: [PATCH 0388/2948] rust: enable `rustdoc::unescaped_backticks` lint

In Rust 1.71.0, `rustdoc` added the `unescaped_backticks` lint, which
detects what are typically typos in Markdown formatting regarding inline
code [1], e.g. from the Rust standard library:

    /// ... to `deref`/`deref_mut`` must ...

    /// ... use [`from_mut`]`. Specifically, ...

It does not seem to have almost any false positives, from the experience
of enabling it in the Rust standard library [2], which will be checked
starting with Rust 1.82.0. The maintainers also confirmed it is ready
to be used.

Thus enable it.

Subject: [PATCH 0390/2948] rust: sync: remove unneeded
 `#[allow(clippy::non_send_fields_in_send_ty)]`

Rust 1.58.0 (before Rust was merged into the kernel) made Clippy's
`non_send_fields_in_send_ty` lint part of the `suspicious` lint group for
a brief window of time [1] until the minor version 1.58.1 got released
a week after, where the lint was moved back to `nursery`.

By that time, we had already upgraded to that Rust version, and thus we
had `allow`ed the lint here for `CondVar`.

Nowadays, Clippy's `non_send_fields_in_send_ty` would still trigger here
if it were enabled.

Moreover, if enabled, `Lock<T, B>` and `Task` would also require an
`allow`. Therefore, it does not seem like someone is actually enabling it
(in, e.g., a custom flags build).

Finally, the lint does not appear to have had major improvements since
then [2].

Thus remove the `allow` since it is unneeded.

Subject: [PATCH 0391/2948] rust: introduce `.clippy.toml`

Some Clippy lints can be configured/tweaked. We will use these knobs to
our advantage in later commits.

This is done via a configuration file, `.clippy.toml` [1]. The file is
currently unstable. This may be a problem in the future, but we can adapt
as needed. In addition, we proposed adding Clippy to the Rust CI's RFL
job [2], so we should be able to catch issues pre-merge.

Thus introduce the file.

Subject: [PATCH 0392/2948] rust: replace `clippy::dbg_macro` with
 `disallowed_macros`

Back when we used Rust 1.60.0 (before Rust was merged in the kernel),
we added `-Wclippy::dbg_macro` to the compilation flags. This worked
great with our custom `dbg!` macro (vendored from `std`, but slightly
modified to use the kernel printing facilities).

However, in the very next version, 1.61.0, it stopped working [1] since
the lint started to use a Rust diagnostic item rather than a path to find
the `dbg!` macro [1]. This behavior remains until the current nightly
(1.83.0).

Therefore, currently, the `dbg_macro` is not doing anything, which
explains why we can invoke `dbg!` in samples/rust/rust_print.rs`, as well
as why changing the `#[allow()]`s to `#[expect()]`s in `std_vendor.rs`
doctests does not work since they are not fulfilled.

One possible workaround is using `rustc_attrs` like the standard library
does. However, this is intended to be internal, and we just started
supporting several Rust compiler versions, so it is best to avoid it.

Therefore, instead, use `disallowed_macros`. It is a stable lint and
is more flexible (in that we can provide different macros), although
its diagnostic message(s) are not as nice as the specialized one (yet),
and does not allow to set different lint levels per macro/path [2].

In turn, this requires allowing the (intentional) `dbg!` use in the
sample, as one would have expected.

Finally, in a single case, the `allow` is fixed to be an inner attribute,
since otherwise it was not being applied.

Subject: [PATCH 0394/2948] rust: provide proper code documentation titles

Rust 1.82.0's Clippy is introducing [1][2] a new warn-by-default lint,
`too_long_first_doc_paragraph` [3], which is intended to catch titles
of code documentation items that are too long (likely because no title
was provided and the item documentation starts with a paragraph).

This lint does not currently trigger anywhere, but it does detect a couple
cases if checking for private items gets enabled (which we will do in
the next commit):

    error: first doc comment paragraph is too long
      --> rust/kernel/init/__internal.rs:18:1
       |
    18 | / /// This is the module-internal type implementing `PinInit` and `Init`. It is unsafe to create this
    19 | | /// type, since the closure needs to fulfill the same safety requirement as the
    20 | | /// `__pinned_init`/`__init` functions.
       | |_
       |
       = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#too_long_first_doc_paragraph
       = note: `-D clippy::too-long-first-doc-paragraph` implied by `-D warnings`
       = help: to override `-D warnings` add `#[allow(clippy::too_long_first_doc_paragraph)]`

      |
      = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#too_long_first_doc_paragraph

Thus clean those two instances.

In addition, since we have a second `std_vendor.rs` file with a similar
header, do the same there too (even if that one does not trigger the lint,
because it is `doc(hidden)`).

Subject: [PATCH 0395/2948] rust: enable Clippy's `check-private-items`

In Rust 1.76.0, Clippy added the `check-private-items` lint configuration
option. When turned on (the default is off), it makes several lints
check private items as well.

In our case, it affects two lints we have enabled [1]:
`missing_safety_doc` and `unnecessary_safety_doc`.

It also seems to affect the new `too_long_first_doc_paragraph` lint [2],
even though the documentation does not mention it.

Thus allow the few instances remaining we currently hit and enable
the lint.

Subject: [PATCH 0396/2948] Documentation: rust: add coding guidelines on lints

In the C side, disabling diagnostics locally, i.e. within the source code,
is rare (at least in the kernel). Sometimes warnings are manipulated
via the flags at the translation unit level, but that is about it.

In Rust, it is easier to change locally the "level" of lints
(e.g. allowing them locally). In turn, this means it is easier to
globally enable more lints that may trigger a few false positives here
and there that need to be allowed locally, but that generally can spot
issues or bugs.

Thus document this.

Subject: [PATCH 0397/2948] rust: start using the `#[expect(...)]` attribute

In Rust, it is possible to `allow` particular warnings (diagnostics,
lints) locally, making the compiler ignore instances of a given warning
within a given function, module, block, etc.

It is similar to `#pragma GCC diagnostic push` + `ignored` + `pop` in C:

    #pragma GCC diagnostic push
    #pragma GCC diagnostic ignored "-Wunused-function"
    static void f(void) {}
    #pragma GCC diagnostic pop

But way less verbose:

    #[allow(dead_code)]
    fn f() {}

By that virtue, it makes it possible to comfortably enable more
diagnostics by default (i.e. outside `W=` levels) that may have some
false positives but that are otherwise quite useful to keep enabled to
catch potential mistakes.

The `#[expect(...)]` attribute [1] takes this further, and makes the
compiler warn if the diagnostic was _not_ produced. For instance, the
following will ensure that, when `f()` is called somewhere, we will have
to remove the attribute:

    #[expect(dead_code)]
    fn f() {}

If we do not, we get a warning from the compiler:

    warning: this lint expectation is unfulfilled
     --> x.rs:3:10
      |
    3 | #[expect(dead_code)]
      |          ^^^^^^^^^
      |
      = note: `#[warn(unfulfilled_lint_expectations)]` on by default

This means that `expect`s do not get forgotten when they are not needed.

See the next commit for more details, nuances on its usage and
documentation on the feature.

The attribute requires the `lint_reasons` [2] unstable feature, but it
is becoming stable in 1.81.0 (to be released on 2024-09-05) and it has
already been useful to clean things up in this patch series, finding
cases where the `allow`s should not have been there.

Thus, enable `lint_reasons` and convert some of our `allow`s to `expect`s
where possible.

This feature was also an example of the ongoing collaboration between
Rust and the kernel -- we tested it in the kernel early on and found an
issue that was quickly resolved [3].

Subject: [PATCH 0398/2948] Documentation: rust: discuss `#[expect(...)]` in
 the guidelines

Discuss `#[expect(...)]` in the Lints sections of the coding guidelines
document, which is an upcoming feature in Rust 1.81.0, and explain that
it is generally to be preferred over `allow` unless there is a reason
not to use it (e.g. conditional compilation being involved).

 false positives but that are otherwise quite useful to keep enabled to catch
 potential mistakes.
 
+On top of that, Rust provides the ``expect`` attribute which takes this further.
+It makes the compiler warn if the warning was not produced. For instance, the
+following will ensure that, when ``f()`` is called somewhere, we will have to
+remove the attribute:
+
+.. code-block:: rust
+
+	#[expect(dead_code)]
+	fn f() {}
+
+If we do not, we get a warning from the compiler::
+
+	warning: this lint expectation is unfulfilled
+	 --> x.rs:3:10
+	  |
+	3 | #[expect(dead_code)]
+	  |          ^^^^^^^^^
+	  |
+	  = note: `#[warn(unfulfilled_lint_expectations)]` on by default
+
+This means that ``expect``\ s do not get forgotten when they are not needed, which
+may happen in several situations, e.g.:
+
+- Temporary attributes added while developing.
+
+- Improvements in lints in the compiler, Clippy or custom tools which may
+  remove a false positive.
+
+- When the lint is not needed anymore because it was expected that it would be
+  removed at some point, such as the ``dead_code`` example above.
+
+It also increases the visibility of the remaining ``allow``\ s and reduces the
+chance of misapplying one.
+
+Thus prefer ``except`` over ``allow`` unless:
+
+- The lint attribute is intended to be temporary, e.g. while developing.
+
+- Conditional compilation triggers the warning in some cases but not others.
+
+  If there are only a few cases where the warning triggers (or does not
+  trigger) compared to the total number of cases, then one may consider using
+  a conditional ``expect`` (i.e. ``cfg_attr(..., expect(...))``). Otherwise,
+  it is likely simpler to just use ``allow``.
+
+- Inside macros, when the different invocations may create expanded code that
+  triggers the warning in some cases but not in others.
+
+- When code may trigger a warning for some architectures but not others, such
+  as an ``as`` cast to a C FFI type.
+
+As a more developed example, consider for instance this program:
+
+.. code-block:: rust
+
+	fn g() {}
+
+	fn main() {
+	    #[cfg(CONFIG_X)]
+	    g();
+	}
+
+Here, function ``g()`` is dead code if ``CONFIG_X`` is not set. Can we use
+``expect`` here?
+
+.. code-block:: rust
+
+	#[expect(dead_code)]
+	fn g() {}
+
+	fn main() {
+	    #[cfg(CONFIG_X)]
+	    g();
+	}
+
+This would emit a lint if ``CONFIG_X`` is set, since it is not dead code in that
+configuration. Therefore, in cases like this, we cannot use ``expect`` as-is.
+
+A simple possibility is using ``allow``:
+
+.. code-block:: rust
+
+	#[allow(dead_code)]
+	fn g() {}
+
+	fn main() {
+	    #[cfg(CONFIG_X)]
+	    g();
+	}
+
+An alternative would be using a conditional ``expect``:
+
+.. code-block:: rust
+
+	#[cfg_attr(not(CONFIG_X), expect(dead_code))]
+	fn g() {}
+
+	fn main() {
+	    #[cfg(CONFIG_X)]
+	    g();
+	}
+
+This would ensure that, if someone introduces another call to ``g()`` somewhere
+(e.g. unconditionally), then it would be spotted that it is not dead code
+anymore. However, the ``cfg_attr`` is more complex than a simple ``allow``.
+
+Therefore, it is likely that it is not worth using conditional ``expect``\ s when
+more than one or two configurations are involved or when the lint may be
+triggered due to non-local changes (such as ``dead_code``).
+

It is cleaner to have a single inner attribute rather than needing
several hidden lines to wrap the macro invocations.

Thus simplify them.

Subject: [PATCH 0400/2948] rust: enable arbitrary_self_types and remove
 `Receiver`

The term "receiver" means that a type can be used as the type of `self`,
and thus enables method call syntax `foo.bar()` instead of
`Foo::bar(foo)`. Stable Rust as of today (1.81) enables a limited
selection of types (primitives and types in std, e.g. `Box` and `Arc`)
to be used as receivers, while custom types cannot.

We want the kernel `Arc` type to have the same functionality as the Rust
std `Arc`, so we use the `Receiver` trait (gated behind `receiver_trait`
unstable feature) to gain the functionality.

The `arbitrary_self_types` RFC [1] (tracking issue [2]) is accepted and
it will allow all types that implement a new `Receiver` trait (different
from today's unstable trait) to be used as receivers. This trait will be
automatically implemented for all `Deref` types, which include our `Arc`
type, so we no longer have to opt-in to be used as receiver. To prepare
us for the change, remove the `Receiver` implementation and the
associated feature. To still allow `Arc` and others to be used as method
receivers, turn on `arbitrary_self_types` feature instead.

This feature gate is introduced in 1.23.0. It used to enable both
`Deref` types and raw pointer types to be used as receivers, but the
latter is now split into a different feature gate in Rust 1.83 nightly.
We do not need receivers on raw pointers so this change would not affect
us and usage of `arbitrary_self_types` feature would work for all Rust
versions that we support (>=1.78).

Subject: [PATCH 0402/2948] rust: add PidNamespace

The lifetime of `PidNamespace` is bound to `Task` and `struct pid`.

The `PidNamespace` of a `Task` doesn't ever change once the `Task` is
alive. A `unshare(CLONE_NEWPID)` or `setns(fd_pidns/pidfd, CLONE_NEWPID)`
will not have an effect on the calling `Task`'s pid namespace. It will
only effect the pid namespace of children created by the calling `Task`.
This invariant guarantees that after having acquired a reference to a
`Task`'s pid namespace it will remain unchanged.

When a task has exited and been reaped `release_task()` will be called.
This will set the `PidNamespace` of the task to `NULL`. So retrieving
the `PidNamespace` of a task that is dead will return `NULL`. Note, that
neither holding the RCU lock nor holding a referencing count to the
`Task` will prevent `release_task()` being called.

In order to retrieve the `PidNamespace` of a `Task` the
`task_active_pid_ns()` function can be used. There are two cases to
consider:

(1) retrieving the `PidNamespace` of the `current` task (2) retrieving
the `PidNamespace` of a non-`current` task

From system call context retrieving the `PidNamespace` for case (1) is
always safe and requires neither RCU locking nor a reference count to be
held. Retrieving the `PidNamespace` after `release_task()` for current
will return `NULL` but no codepath like that is exposed to Rust.

Retrieving the `PidNamespace` from system call context for (2) requires
RCU protection. Accessing `PidNamespace` outside of RCU protection
requires a reference count that must've been acquired while holding the
RCU lock. Note that accessing a non-`current` task means `NULL` can be
returned as the non-`current` task could have already passed through
`release_task()`.

To retrieve (1) the `current_pid_ns!()` macro should be used which
ensure that the returned `PidNamespace` cannot outlive the calling
scope. The associated `current_pid_ns()` function should not be called
directly as it could be abused to created an unbounded lifetime for
`PidNamespace`. The `current_pid_ns!()` macro allows Rust to handle the
common case of accessing `current`'s `PidNamespace` without RCU
protection and without having to acquire a reference count.

For (2) the `task_get_pid_ns()` method must be used. This will always
acquire a reference on `PidNamespace` and will return an `Option` to
force the caller to explicitly handle the case where `PidNamespace` is
`None`, something that tends to be forgotten when doing the equivalent
operation in `C`. Missing RCU primitives make it difficult to perform
operations that are otherwise safe without holding a reference count as
long as RCU protection is guaranteed. But it is not important currently.
But we do want it in the future.

Note for (2) the required RCU protection around calling
`task_active_pid_ns()` synchronizes against putting the last reference
of the associated `struct pid` of `task->thread_pid`. The `struct pid`
stored in that field is used to retrieve the `PidNamespace` of the
caller. When `release_task()` is called `task->thread_pid` will be
`NULL`ed and `put_pid()` on said `struct pid` will be delayed in
`free_pid()` via `call_rcu()` allowing everyone with an RCU protected
access to the `struct pid` acquired from `task->thread_pid` to finish.

Use the new api DECLARE_TASKLET instead of DECLARE_TASKLET_OLD
introduced in commit 12cc923f1ccc ("tasklet: Introduce new

 uNextPktTime variable
MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

This patch renames uNextPktTime to next_pkt_time in s_uGetDataDuration
function in order to avoid using camel case.

 struct i2c_device_id::driver_data to 0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

While touching the initializer, also remove the comma after the sentinel
entry.

Subject: [PATCH 0456/2948] staging: Switch back to struct
 platform_driver::remove()

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all staging drivers to use .remove(), with the eventual goal to
drop struct platform_driver::remove_new(). As .remove() and .remove_new()
have the same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

Subject: [PATCH 0460/2948] staging: vchiq_core: Use killable wait completions
 for bulk transfers

commit f27e47bc6b8b ("staging: vchiq: use completions instead of
semaphores") introduced completions for events in vchiq interface.
It introduced _interruptible() version of completions for waiting
on events. However, it missed a subtle down_interruptible() macro
override in vchiq_killable.h, which used to mask most of the signals
and only interrupt on fatal ones.

The above issue was fixed in commit a772f116702e ("staging: vchiq: switch
to wait_for_completion_killable"). Given the override logic of
down_interruptible() that existed in vchiq_killable.h, that commit
fixed the completions with the correct variation i.e. killable() family
of functions.

However, commit a772f116702e ("staging: vchiq: switch to
wait_for_completion_killable") later got reverted [1] due to high CPU
load noticed by various downstream and upstream distributions [2].
Reverting the commit solved this problem but the root cause was never
diagonsed and the entire commit was reverted.

This patch brings back killable version of wait events but only for
bulk transfers and queue_message() transfer code paths.

The idea is to bring back killable versions for various event
completions in a phased manner so that we do not re-regress again as
noticed in [2]. Hence, no other wait events are converted from
interruptible -> killable in this patch.

Since the bulk transfers are no longer interruptible (but killable),
drop the "_interruptible" suffix from all vchiq_bulk_xfer_* functions.

Subject: [PATCH 0461/2948] staging: vchiq_core: Return on all errors from
 queue_message()

In vchiq_connect_internal(), a MAKE_CONNECT message is queued
if the connection is disconnected, but only -EAGAIN error is
checked on the error path and returned.

However, queue_message() can fail with other errors as well hence,
vchiq_connect_internal() should return in those cases as well.

Subject: [PATCH 0462/2948] staging: vchiq_core: Return -EINTR in
 queue_message() on interrupt

queue_message() uses mutex_lock_killable() and
wait_for_completion_killable() variations of locking and wait event
completions respectively. These functions return either 0 (on success)
or -EINTR, if interrupted by a fatal signal (as documented in the
kernel).

However, queue_message() is currently returning -EAGAIN if these
killable functions are interrupted by fatal signals. Bubbling up
-EAGAIN might give a sense to the caller, that the code path can
be re-tried however, in actual sense, a fatal signal has been
received by the process and the process is going away.

Hence, we should align the return value with what these killable
versions will return i.e. -EINTR (Interrupted system call).

Subject: [PATCH 0463/2948] staging: vchiq_core: Return -EINTR when bulk
 transfers are interrupted

Bulk transfers for various VCHIQ modes use mutex_lock_killable() and
wait_for_completion_killable() variations. Currently, -EAGAIN is
returned if these are interrupted by a fatal signal.

-EAGAIN may mislead the caller into thinking the operation can be
retried, while in reality, the process has received a fatal signal
and is terminating. Therefore, we should update the return value to
align with what these killable functions would return, specifically
-EINTR (Interrupted system call).

The function remote_event_signal() is declared in vchiq_core.h while
defined in vchiq_arm.c and used only in vchiq_core.c. Move the
definition to vchiq_core.c as it is only used in this file.

Also convert it to static and drop the function signature from
vchiq_core.h header. BELL2 doorbell macro is also moved from vchiq_arm
to vchiq_core as part of this change.

No functional changes intended in this patch.

Subject: [PATCH 0467/2948] staging: vchiq_core: Move bulk data functions in
 vchiq_core

Bulk transfers core logic lives in vchiq_core.c, hence move all
the preparatory bulk data allocation helpers to vchiq_core.c (from
vchiq_arm).

The discrepancy was noticed when vchiq_prepare_bulk_data() and
vchiq_complete_bulk() are being used vchiq_core.c but are defined
in vchiq_arm. Now that they are now confined to vchiq_core.c,
they can be made static and their signatures from vchiq_core header
can be dropped.

vchiq_prepare_bulk_data() and vchiq_complete_bulk() depends on
struct vchiq_pagelist_info, cleanup_pagelist(), free_pagelist() and
create_pagelist() hence they are pulled in from vchiq_arm as well,
as part of this commit.

No functional changes intended in this patch.

Subject: [PATCH 0468/2948] staging: vchiq_core: Drop vchiq_pagelist.h

vchiq_pagelist.h only defines one struct and a couple of macros.
It can be merged with vchiq_core since all the pagelist related
function helpers are now in vchiq_core for bulk transfers.

Move the struct and related macros to vchiq_core header and drop
vchiq_pagelist.h.

Subject: [PATCH 0470/2948] rust: miscdevice: add base miscdevice abstraction

Provide a `MiscDevice` trait that lets you specify the file operations
that you wish to provide for your misc device. For now, only three file
operations are provided: open, close, ioctl.

These abstractions only support MISC_DYNAMIC_MINOR. This enforces that
new miscdevices should not hard-code a minor number.

When implementing ioctl, the Result type is used. This means that you
can choose to return either of:
* An integer of type isize.
* An errno using the kernel::error::Error type.
When returning an isize, the integer is returned verbatim. It's mainly
intended for returning positive integers to userspace. However, it is
technically possible to return errors via the isize return value too.

To avoid having a dependency on files, this patch does not provide the
file operations callbacks a pointer to the file. This means that they
cannot check file properties such as O_NONBLOCK (which Binder needs).
Support for that can be added as a follow-up.

To avoid having a dependency on vma, this patch does not provide any way
to implement mmap (which Binder needs). Support for that can be added as
a follow-up.

Rust Binder will use these abstractions to create the /dev/binder file
when binderfs is disabled.

and this affects the start index of TINT interrupts (1 + 16 = 17, rather
than 1 + 8 = 9).
Macro RZG2L_TINT_IRQ_START_INDEX cannot work anymore, replace it with a
new member within struct rzg2l_hwcfg.

Subject: [PATCH 0478/2948] perf probe: Remove unused add_perf_probe_events

add_perf_probe_events has been unused since 2015's commit
b02137cc6550 ("perf probe: Move print logic into cmd_probe()")
which confusingly now uses perf_add_probe_events.

Remove it.

`dbg!` contains adapted code from Rust upstream. Compare the kernel
code with the Rust upstream one and update missing column numbers in
`dbg!` outputs.

Column numbers are not copied but adjusted for the kernel's examples.

 backend

Add a non-blocking trylock method to lock backend interface, mutex and
spinlock implementations. It includes a C helper for spin_trylock.

Rust Binder will use this method together with the new shrinker
abstractions to avoid deadlocks in the memory shrinker.

Subject: [PATCH 0482/2948] rust: error: optimize error type to use nonzero

Optimize `Result<(), Error>` size by changing `Error` type to
`NonZero*` for niche optimization.

This reduces the space used by the `Result` type, as the `NonZero*`
type enables the compiler to apply more efficient memory layout.
For example, the `Result<(), Error>` changes size from 8 to 4 bytes.

Refactor the `FromBytes` and `AsBytes` traits from `types.rs` into a new
`transmute.rs` module:

 - Add `rust/kernel/transmute.rs` with the definitions of `FromBytes`
   and `AsBytes`.

 - Remove the same trait definitions from `rust/kernel/types.rs`.

 - Update `rust/kernel/uaccess.rs` to import `AsBytes` and `FromBytes`
   from `transmute.rs`.

The traits and their implementations remain unchanged.

Subject: [PATCH 0484/2948] staging: rts5208: Remove unused driver

Wei Wang from Realsil contributed this driver in 2011.

The following reasons lead to the removal:
- This driver generates maintenance workload
- Did not find minimal documentation on the web.
- No blog entries about anyone using the rts5208 and rts5288 during the
  last years.
- Did not find any device that may has it in and is still available on
  the market.

The x86 port of UM has efficient unaligned access. Set the option as it
is appropriate and will e.g. cause UBSAN to not enable unaligned memory
access checking by default.

Subject: [PATCH 0490/2948] um: Remove the redundant declaration of
 high_physmem

high_physmem has already been declared in as-layout.h, so there is
no need to declare it explicitly in the .c file again.

While at it, group the declarations of __real_malloc and __real_free
together to make the code slightly more readable.

Subject: [PATCH 0491/2948] um: Fix potential integer overflow during physmem
 setup

This issue happens when the real map size is greater than LONG_MAX,
which can be easily triggered on UML/i386.

Subject: [PATCH 0492/2948] um: Remove highmem leftovers

Highmem was only supported on UML/i386. And the support has been
removed by commit a98a6d864d3b ("um: Remove broken highmem support").
Remove the leftovers and stop UML from trying to setup highmem when
the sum of physmem_size and iomem_size exceeds max_physmem.

Subject: [PATCH 0493/2948] um: Fix the definition for physmem_size

Currently physmem_size is defined as long long but declared locally
as unsigned long long before using it in separate .c files. Make them
match by defining physmem_size as unsigned long long and also move
the declaration to a common header to allow the compiler to check it.

Subject: [PATCH 0495/2948] um: always use the internal copy of the FP
 registers

When switching from userspace to the kernel, all registers including the
FP registers are copied into the kernel and restored later on. As such,
the true source for the FP register state is actually already in the
kernel and they should never be grabbed from the userspace process.

Change the various places to simply copy the data from the internal FP
register storage area. Note that on i386 the format of PTRACE_GETFPREGS
and PTRACE_GETFPXREGS is different enough that conversion would be
needed. With this patch, -EINVAL is returned if the non-native format is
requested.

The upside is, that this patchset fixes setting registers via ptrace
(which simply did not work before) as well as fixing setting floating
point registers using the mcontext on signal return on i386.

Subject: [PATCH 0496/2948] um: Remove 3-level page table support on i386

The highmem support has been removed by commit a98a6d864d3b ("um:
Remove broken highmem support"). The 2-level page table is sufficient
on UML/i386 now. Remove the 3-level page table support on UML/i386
which is still marked as experimental.

 CC_CAN_LINK_STATIC_NO_RUNTIME_DEPS

CC_CAN_LINK_STATIC_NO_RUNTIME_DEPS is not defined anywhere.

In the submitted patch set [1], the first patch "um/kconfig: introduce
CC_CAN_LINK_STATIC_NO_RUNTIME_DEPS" was not applied.

Only 2/3 and 3/3 were applied, which are now:

 - 730586ff7fad ("um: Allow static linking for non-glibc implementations")
 - 5e1121cd43d4 ("um: Some fixes to build UML with musl")

Given that nobody has noticed the missing first patch for many years,
it seems it was unnecessary.

Subject: [PATCH 0498/2948] um: remove auxiliary FP registers

We do not need the extra save/restore of the FP registers when getting
the fault information. This was originally added in commit 2f56debd77a8
("uml: fix FP register corruption") but at that time the code was not
saving/restoring the FP registers when switching to userspace. This was
fixed in commit fbfe9c847edf ("um: Save FPU registers between task
switches") and since then the auxiliary registers have not been useful.

Subject: [PATCH 0499/2948] um: Add generic stub_syscall1 function

The 64bit version did not have a stub_syscall1 function yet. Add it as
it will be useful to implement a static binary for stub loading.

Subject: [PATCH 0500/2948] um: use execveat to create userspace MMs

Using clone will not undo features that have been enabled by libc. An
example of this already happening is rseq, which could cause the kernel
to read/write memory of the userspace process. In the future the
standard library might also use mseal by default to protect itself,
which would also thwart our attempts at unmapping everything.

Solve all this by taking a step back and doing an execve into a tiny
static binary that sets up the minimal environment required for the
stub without using any standard library. That way we have a clean
execution environment that is fully under the control of UML.

Note that this changes things a bit as the FDs are not anymore shared
with the kernel. Instead, we explicitly share the FDs for the physical
memory and all existing iomem regions. Doing this is fine, as iomem
regions cannot be added at runtime.

Subject: [PATCH 0502/2948] um: Set parent death signal for winch
 thread/process

The winch "thread" is really a separate process. Using prctl to set
PR_SET_PDEATHSIG ensures that this separate thread will be killed if the
UML kernel itself dies unexpectedly and does not perform proper cleanup.

The code assumes that the stub code can fit into a single page. This is
unlikely to ever change, but add a link time assert instead so that
there will be no hard to debug error.

Subject: [PATCH 0504/2948] um: Calculate stub data address relative to stub
 code

Instead of using the current stack pointer, we can also use the current
instruction to calculate where the stub data is. With this the stub data
only needs to be aligned to a full page boundary.

Changing this has the advantage that we do not have a hole in the memory
space above the stub data (which would need to be explicitly cleared).

Another motivation to do this is that with the planned addition of a
SECCOMP based userspace the stack pointer may not be fully trustworthy.

We may have a TASK_SIZE from the host that is bigger than UML is able to
address with a three-level pagetable on 64-bit. Guard against that by
clipping the maximum TASK_SIZE to the maximum addressable area.

Subject: [PATCH 0506/2948] um: Discover host_task_size from envp

When loading the UML binary, the host kernel will place the stack at the
highest possible address. It will then map the program name and
environment variables onto the start of the stack.

As such, an easy way to figure out the host_task_size is to use the
highest pointer to an environment variable as a reference.

Ensure that this works by disabling address layout randomization and
re-executing UML in case it was enabled.

This increases the available TASK_SIZE for 64 bit UML considerably.

Subject: [PATCH 0507/2948] um: clear all memory in new userspace processes

With the change to use execve() we can now safely clear the memory up to
STUB_START as rseq will not be trying to use memory in that region. Also,
on 64 bit the previous changes should mean that there is no usable
memory range above the stub.

Make the change and remove the comment as it is not needed anymore.

Subject: [PATCH 0508/2948] um: Switch to 4 level page tables on 64 bit

The larger memory space is useful to support more applications inside
UML. One example for this is ASAN instrumentation of userspace
applications which requires addresses that would otherwise not be
available.

Subject: [PATCH 0509/2948] soundwire: intel_auxdevice: add kernel parameter
 for mclk divider

Add a kernel parameter to work-around discrepancies between hardware
and platform firmware, it's not unusual to see e.g. 38.4MHz listed in
_DSD properties as the SoundWire clock source, but the hardware may be
based on a 19.2 MHz mclk source.

Subject: [PATCH 0513/2948] staging: gpib: Add user api include files

User api include files used by drivers and userland code.
The files are also distributed with the userland package.
Since these include files have been used by many applications we
had to keep the camelCase enums, typedefs and uint8_t declarations.

+ *  The following code is a modified version of the USB Skeleton driver	     *
+ *  written by Greg Kroah-Hartman and available in the kernel tree.	     *
+ *									     *
+ *  Functions skel_open() and skel_release() have been rewritten and named   *
+ *  skel_do_open() and skel_do_release() to process the attach and detach    *
+ *  requests coming from gpib_config.					     *
+ *									     *
+ *  Functions skel_read() and skel_write() have been split into a	     *
+ *  skel_do_read() and skel_do_write(), that cover the kernel stuff of read  *
+ *  and write operations, and the original skel_read() and skel_write(),     *
+ *  that handle communication with user space and call their _do_ companion. *
+ *									     *
+ *  Only the _do_ versions are used by the lpvo_usb_gpib driver; other ones  *
+ *  can be (optionally) maintained in the compilation to have direct access  *
+ *  to a gpib controller for debug and diagnostics.			     *
+ *									     *
+ *  To avoid collisions in names, devices in user space have been renamed    *
+ *  lpvo_raw1, lpvo_raw2 ....  and the usb driver has been renamed with the  *
+ *  gpib module name.							     *

Subject: [PATCH 0532/2948] staging: gpib: disable CONFIG_GPIB_KERNEL_DEBUG

It breaks the build so disable that option for now.

It shouldn't be needed anyway, the normal in-kernel debugging facilities
should be used instead.

To use spi_get_device_match_data(), add the chip_info structure to the
of_device_id table which is always a good thing to do.

While at it, added dedicated variables for each chip (instead of the
harder to maintain array) and added a new string variable for the part
name.

Subject: [PATCH 0538/2948] iio: frequency: adf4371: drop spi_set_drvdata()

spi_set_drvdata() is not needed as there's no spi_get_drvdata() call in
the code.

We already cache clkin rate during probe and then never use the clk

Subject: [PATCH 0542/2948] iio: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/iio/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

While touching these files, make indention of the struct initializer
consistent in several files.

Subject: [PATCH 0545/2948] resource: Add resource set range and size helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Setting the end address for a resource with a given size lacks a helper and
is therefore coded manually unlike the getter side which has a helper for
resource size calculation. Also, almost all callsites that calculate the
end address for a resource also set the start address right before it like
this:

  res->start = start_addr;
  res->end = res->start + size - 1;

Add resource_set_range(res, start_addr, size) that sets the start address
and calculates the end address to simplify this often repeated fragment.

Also add resource_set_size() for the cases where setting the start address
of the resource is not necessary but mention in its kerneldoc that
resource_set_range() is preferred when setting both addresses.

Subject: [PATCH 0546/2948] PCI: Use resource_set_{range,size}() helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Convert open-coded resource size calculations to use
resource_set_{range,size}() helpers.

While at it, use SZ_* for size parameter where appropriate which makes the
intent of code more obvious.

Also, cast sizes to resource_size_t, not u64.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

pci_bus_distribute_available_resources() performs alignment in case of
non-zero alignment requirement on three occasions.

Add ALIGN_DOWN_IF_NONZERO() helper to avoid coding the non-zero check three
times.

Subject: [PATCH 0549/2948] staging: vt6655: Remove unused driver

Forest Bond contributed this driver in 2009.

The following reasons lead to the removal:
- This driver generates maintenance workload
- This driver has a maximum 54MBit/s as it supports only 802.11 b/g.
  Peak throughput is 3MBytes/s but this lasts only for a second.
  Typically throughput is 1.7MBytes/s.
- Depending on the number of devices on the channel the device looses
  connection and cannot reconnect for 5-60 seconds. Watching a youtube
  video is OK because of the buffer. But surfing can then be really a
  pain.
- Its form factor is mini PCI (not miniPCIe) that is old and large.
- Hardly not to buy.

Subject: [PATCH 0550/2948] staging: gdm724x: Remove unused driver

Won Kang from gct contributed the driver in 2013.

The following reasons lead to the removal:
- This driver generates maintenance workload
- The manufacturer is not interested and does not care as Emails or
  inquiries, to support or involved persons of gct, got unanswered.
- Did not find a possibility to buy the chips.
- Did not find minimal documentation on the web.
- Did not find a device where it is build in and the user is able to
  install any Linux. Therefore it is not possible to do any testing of
  the driver from the community.
- No blog entries about anyone using the gdmtty and gdmulte.
- No response about usage of this drivers to the Email from April 2024

Subject: [PATCH 0553/2948] serial: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/tty/serial to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

Subject: [PATCH 0562/2948] serial: sc16is7xx: announce support for
 SER_RS485_RTS_ON_SEND

When specifying flag SER_RS485_RTS_ON_SEND in RS485 configuration,
we get the following warning after commit 4afeced55baa ("serial: core:
fix sanitizing check for RTS settings"):

    invalid RTS setting, using RTS_AFTER_SEND instead

This results in SER_RS485_RTS_AFTER_SEND being set and the
driver always write to the register field SC16IS7XX_EFCR_RTS_INVERT_BIT,
which breaks some hardware using these chips.

The hardware supports both RTS_ON_SEND and RTS_AFTER_SEND modes, so fix
this by announcing support for RTS_ON_SEND.

Add implementations for the nbcon consoles (write_atomic, write_thread,
driver_enter, driver_exit) and add CON_NBCON to the initial flags.

The legacy code is kept in order to easily switch back to legacy mode
by defining CONFIG_SERIAL_IMX_LEGACY_CONSOLE.

Subject: [PATCH 0567/2948] perf pmu: Allow hardcoded terms to be applied to
 attributes

Hard coded terms like "config=10" are skipped by perf_pmu__config
assuming they were already applied to a perf_event_attr by parse
event's config_attr function. When doing a reverse number to name
lookup in perf_pmu__name_from_config, as the hardcoded terms aren't
applied the config value is incorrect leading to misses or false
matches. Fix this by adding a parameter to have perf_pmu__config apply
hardcoded terms too (not just in parse event's config_term_common).

From 240505b2d0adcdc8fd018117e88dc27b09734735 Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>
Date: Tue, 1 Oct 2024 20:20:07 -0700
Subject: [PATCH 0569/2948] perf tool_pmu: Factor tool events into their own
 PMU

Rather than treat tool events as a special kind of event, create a
tool only PMU where the events/aliases match the existing
duration_time, user_time and system_time events. Remove special
parsing and printing support for the tool events, but add function
calls for when PMU functions are called on a tool_pmu.

Move the tool PMU code in evsel into tool_pmu.c to better encapsulate
the tool event behavior in that file.

From 0709a82c10bb98d0426dd289a6b8c143f61a8786 Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>
Date: Tue, 1 Oct 2024 20:20:08 -0700
Subject: [PATCH 0570/2948] perf tool_pmu: Rename enum perf_tool_event to
 tool_pmu_event

To better reflect the events listed are from the tool PMU. Rename the
enum values from PERF_TOOL_* to TOOL_PMU__EVENT_*.

Subject: [PATCH 0572/2948] perf tool_pmu: Move expr literals to tool_pmu

Add the expr literals like "#smt_on" as tool events, this allows stat
events to give the values. On my laptop with hyperthreading enabled:

```
$ perf stat -e "has_pmem,num_cores,num_cpus,num_cpus_online,num_dies,num_packages,smt_on,system_tsc_freq" true

 Performance counter stats for 'true':

                 0      has_pmem
                 8      num_cores
                16      num_cpus
                16      num_cpus_online
                 1      num_dies
                 1      num_packages
                 1      smt_on
     2,496,000,000      system_tsc_freq

       0.001113637 seconds time elapsed

       0.001218000 seconds user
       0.000000000 seconds sys
```

And with hyperthreading disabled:
```
$ perf stat -e "has_pmem,num_cores,num_cpus,num_cpus_online,num_dies,num_packages,smt_on,system_tsc_freq" true

 Performance counter stats for 'true':

                 0      has_pmem
                 8      num_cores
                16      num_cpus
                 8      num_cpus_online
                 1      num_dies
                 1      num_packages
                 0      smt_on
     2,496,000,000      system_tsc_freq

       0.000802115 seconds time elapsed

       0.000000000 seconds user
       0.000806000 seconds sys
```

As zero matters for these values, in stat-display
should_skip_zero_counter only skip the zero value if it is not the
first aggregation index.

The tool event implementations are used in expr but not evaluated as
events for simplicity. Also core_wide isn't made a tool event as it
requires command line parameters.

Subject: [PATCH 0573/2948] perf jevents: Add tool event json under a common
 architecture

Introduce the notion of a common architecture/model that can be used
to find event tables for common PMUs like the tool PMU. By having tool
events be json standard PMU attribute configuration, descriptions,
etc. can be used and these routines are already optimized for things
like binary searching.

Subject: [PATCH 0574/2948] perf tool_pmu: Switch to standard pmu functions and
 json descriptions

Use the regular PMU approaches with tool json events to reduce the
amount of special tool_pmu code - tool_pmu__config_terms and
tool_pmu__for_each_event_cb are removed. Some functions remain, like
tool_pmu__str_to_event, as conveniences to metricgroups. Add
tool_pmu__skip_event/tool_pmu__num_skip_events to handle the case that
tool json events shouldn't appear on certain architectures. This isn't
done in jevents.py due to complexity in the empty-pmu-events.c and
when all vendor json is built into the tool.

Subject: [PATCH 0575/2948] perf tests: Add tool PMU test

Ensure parsing with and without PMU creates events with the expected
config values. This ensures the tool.json doesn't get out of sync with
tool_pmu_event enum.

Subject: [PATCH 0576/2948] perf report: Display columns Predicted/Abort/Cycles
 in --branch-history

The original commit message:

"
Use current sort mechanism but the real .se_cmp() just returns 0 so
that new columns "Predicted", "Abort" and "Cycles" are created in display
but actually these keys are not the sort keys.

For example:

Overhead  Source:Line   Symbol    Shared Object  Predicted  Abort  Cycles
........  ............  ........  .............  .........  .....  ......

  38.25%  div.c:45      [.] main  div            97.6%      0      3
"

Update missed commit from series "perf report: Show branch flags/cycles
in --branch-history callgraph view" to apply to current repository so that
new columns described above are visible.

Subject: [PATCH 0577/2948] misc: eeprom: eeprom_93cx6: Add quirk for extra
 read clock cycle

Add a quirk similar to eeprom_93xx46 to add an extra clock cycle before
reading data from the EEPROM.

The 93Cx6 family of EEPROMs output a "dummy 0 bit" between the writing
of the op-code/address from the host to the EEPROM and the reading of
the actual data from the EEPROM.

More info can be found on page 6 of the AT93C46 datasheet (linked below).
Similar notes are found in other 93xx6 datasheets.

In summary the read operation for a 93Cx6 EEPROM is:
Write to EEPROM:	110[A5-A0]	(9 bits)
Read from EEPROM:	0[D15-D0]	(17 bits)

Where:
	110 is the start bit and READ OpCode
	[A5-A0] is the address to read from
	0 is a "dummy bit" preceding the actual data
	[D15-D0] is the actual data.

Looking at the READ timing diagrams in the 93Cx6 datasheets the dummy
bit should be clocked out on the last address bit clock cycle meaning it
should be discarded naturally.

However, depending on the hardware configuration sometimes this dummy
bit is not discarded. This is the case with Exar PCI UARTs which require
an extra clock cycle between sending the address and reading the data.

Subject: [PATCH 0579/2948] serial: 8250_exar: Replace custom EEPROM read with
 eeprom_93cx6

Replace the custom 93cx6 EEPROM read functions with the eeprom_93cx6
driver. This removes duplicate code and improves code readability.

Replace exar_ee_read() calls with eeprom_93cx6_read() or
eeprom_93cx6_multiread().

Add "select EEPROM_93CX6" to config SERIAL_8250_EXAR to ensure
eeprom_93cx6 driver is also compiled when 8250_exar driver is selected.

Note: Old exar_ee_read() and associated functions are removed in next
patch in this series.

Link to mailing list discussion with Andy Shevchenko for reference.

Subject: [PATCH 0588/2948] pinctrl: th1520: Fix pinconf return values

When Drew took over the pinctrl driver he must have changed
all the -ENOTSUPP returns into -EOPNOTSUPP. This subtle change
was most likely not spotted because it was never mentioned in the
changelog of the patchset, but it breaks all the places in the
pin control and GPIO frameworks where -ENOTSUPP is expected.

Subject: [PATCH 0589/2948] pinctrl: th1520: Update pinmux tables

When Drew took over the pinctrl driver it seems like he didn't use the
git tree I pointed him at and thus missed some important fixes to the
tables describing valid pinmux settings.

The documentation has a nice overview table of these settings but
unfortunately it doesn't fully match the register descriptions, which

Subject: [PATCH 0591/2948] pinctrl: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/pinctrl to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

Subject: [PATCH 0595/2948] PCI: endpoint: Introduce
 pci_epc_function_is_valid()

Introduce the epc core helper function pci_epc_function_is_valid() to
verify that an epc pointer, a physical function number and a virtual
function number are all valid. This avoids repeating the code pattern:

if (IS_ERR_OR_NULL(epc) || func_no >= epc->max_functions)
	return err;

if (vfunc_no > 0 && (!epc->max_vfs || vfunc_no > epc->max_vfs[func_no]))
	return err;

in many functions of the endpoint controller core code.

Subject: [PATCH 0596/2948] PCI: endpoint: Improve pci_epc_mem_alloc_addr()

There is no point in attempting to allocate memory from an endpoint
controller memory window if the requested size is larger than the memory
window size. Add a check to skip bitmap_find_free_region() calls for
such case. This check can be done without the mem->lock mutex held as
memory window sizes are constant and never modified at runtime.
Also change the final return to return NULL to simplify the code.

[Analysis]
The first is AA lock, it because wrong logic, it need a unlock.
The second is AB lock, it needs to rearrange the order of lock usage.

Recent tests on Raspberry Pi 3 B Plus have shown that one
iteration is not enough to discover issues reliable. So
switch back to the defaults (1000 iterations).

Subject: [PATCH 0601/2948] staging: vchiq_core: Locally cache cache_line_size
 information

Locally cache 'cache_line_size' information in a variable instead of
repeatedly accessing it from drv_mgmt->info. This helps to reflow lines
under 80 columns.

No functional change intended in this patch.

Subject: [PATCH 0605/2948] staging: vchiq_core: Lower indentation in
 parse_open()

If the service is not in VCHIQ_SRVSTATE_LISTENING state, it is
implied that the message is dealt with and parse_open() should return.
If this is the case, simply jump the code flow to return site using
'goto done;' statement.

This helps to lower the indentation of
	if (service->srvstate == VCHIQ_SRVSTATE_LISTENING)
conditional branch.

No functional changes intended in this patch.

Subject: [PATCH 0609/2948] staging: rtl8712: Introduce auth_algorithm macros
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, auth_algorithm is assigned/compared to using hardcoded
numbers. Some of the lines are commented, some of them are not.

This patch introduces macros that replace numeric assignments and
comparisons of auth_algorithm, increasing readability.

Subject: [PATCH 0610/2948] staging: vt6656: Remove unused driver

Forest Bond contributed this driver in 2009.

The following reasons lead to the removal:
- This driver generates maintenance workload
- This driver has a maximum 54MBit/s as it supports only 802.11 b/g.
  Peak throughput is 3MBytes/s.
- ping times can be 17ms are often above 500ms and worst case 22 seconds.
  One other user does not see such long ping times using a rasperry pi.

I suggest deleting the driver as it no longer meets current expectations
for throuput.

Subject: [PATCH 0619/2948] binder: fix OOB in binder_add_freeze_work()

In binder_add_freeze_work() we iterate over the proc->nodes with the
proc->inner_lock held. However, this lock is temporarily dropped to
acquire the node->lock first (lock nesting order). This can race with
binder_deferred_release() which removes the nodes from the proc->nodes
rbtree and adds them into binder_dead_nodes list. This leads to a broken
iteration in binder_add_freeze_work() as rb_next() will use data from
binder_dead_nodes, triggering an out-of-bounds access:

  ==================================================================
  BUG: KASAN: global-out-of-bounds in rb_next+0xfc/0x124
  Read of size 8 at addr ffffcb84285f7170 by task freeze/660

  The buggy address belongs to the variable:
   binder_dead_nodes+0x10/0x40
  [...]
  ==================================================================

This is possible because proc->nodes (rbtree) and binder_dead_nodes
(list) share entries in binder_node through a union:

	struct binder_node {
	[...]
		union {
			struct rb_node rb_node;
			struct hlist_node dead_node;
		};

Fix the race by checking that the proc is still alive. If not, simply
break out of the iteration.

When a binder reference is cleaned up, any freeze work queued in the
associated process should also be removed. Otherwise, the reference is
freed while its ref->freeze.work is still queued in proc->work leading
to a use-after-free issue as shown by the following KASAN report:

Subject: [PATCH 0621/2948] binder: fix BINDER_WORK_FROZEN_BINDER debug logs

The BINDER_WORK_FROZEN_BINDER type is not handled in the binder_logs
entries and it shows up as "unknown work" when logged:

  proc 649
  context binder-test
    thread 649: l 00 need_return 0 tr 0
    ref 13: desc 1 node 8 s 1 w 0 d 0000000053c4c0c3
    unknown work: type 10

This patch add the freeze work type and is now logged as such:

  proc 637
  context binder-test
    thread 637: l 00 need_return 0 tr 0
    ref 8: desc 1 node 3 s 1 w 0 d 00000000dc39e9c6
    has frozen binder

Subject: [PATCH 0623/2948] binder: allow freeze notification for dead nodes

Alice points out that binder_request_freeze_notification() should not
return EINVAL when the relevant node is dead [1]. The node can die at
any point even if the user input is valid. Instead, allow the request
to be allocated but skip the initial notification for dead nodes. This
avoids propagating unnecessary errors back to userspace.

Subject: [PATCH 0624/2948] binder: fix memleak of proc->delivered_freeze

If a freeze notification is cleared with BC_CLEAR_FREEZE_NOTIFICATION
before calling binder_freeze_notification_done(), then it is detached
from its reference (e.g. ref->freeze) but the work remains queued in
proc->delivered_freeze. This leads to a memory leak when the process
exits as any pending entries in proc->delivered_freeze are not freed:

This patch fixes the leak by ensuring that any pending entries in
proc->delivered_freeze are freed during binder_deferred_release().

Subject: [PATCH 0630/2948] misc: keba: Use capital letters for I2C error
 message

Print "I2C" instead of "i2c" in error message as "I2C" is the official
name for the bus.

Subject: [PATCH 0631/2948] misc: keba: Add SPI controller device

Add support for the SPI controller auxiliary device. This enables access
to the SPI flash of the FPGA and some other SPI devices.

The actual list of SPI devices is detected by reading some bits out of
the previously registered I2C EEPROM.

Subject: [PATCH 0632/2948] misc: keba: Add LAN9252 driver

KEBA CP500 devices use the LAN9252 controller for EtherCAT
communication. For a stable Ethernet link the PHY registers of the
controller need to be configured correctly. This driver configures these
PHY registers as required.

Subject: [PATCH 0633/2948] misc: keba: Support EEPROM sections as separate
 devices

The main EEPROM of KEBA CP500 devices is divided into two sections. One
section for type label data like device name, order number, serial
number and so on. The second section is reserved for arbitrary data
stored by the user.

The two sections have a defined range. The first 3 kB for the type label
and the remaining 1 kB for user data. The type label is written during
production and can fill up the whole 3 kB. Thus, the range is fixed and
cannot be changed dynamically.

The two sections cannot be presented as NVMEM cells. A NVMEM cell is
always read and written at once, because the data presented to the user
can differ from the data stored in the physical NVMEM cell. Thus, NVMEM
cells would lead to reading 3 kB for every type label access, even if
only the device name is read. So performance would suffer. But it is
also an indication that NVMEM cells are designed for small data cells
within NVMEM devices.

Register separate NVMEM devices for every section. This enables safe
access to every section. Also different access rights are then possible.

This 'memmap_ktype' is not modified. It is only used in
firmware_map_add_entry().

Constifying this structure and moving it to a read-only section,
and this can increase over all security.

Subject: [PATCH 0638/2948] PCI/DOE: Poll DOE Busy bit for up to 1 second in
 pci_doe_send_req()

During initial device probe, the PCI DOE busy bit for some CXL devices may
be left set for a longer period than expected by the current driver logic.
Despite local comments stating DOE Busy is unlikely to be detected, it
appears commonly specifically during boot when CXL devices are being
probed.

The symptom was messages like this:

  endpoint6: DOE failed -EBUSY

produced by cxl_cdat_get_length() or cxl_cdat_read_table().

This was observed on a single socket AMD platform with 2 CXL memory
expanders attached to the single socket. It was not the case that
concurrent accesses were being made, as validated by monitoring mailbox
commands on the device side.

This behavior has been observed with multiple CXL memory expanders from
different vendors - so it appears unrelated to the model.

In all observed tests, only a small period of the retry window is actually
used - typically only a handful of loop iterations.

Polling on the PCI DOE Busy Bit for (at max) one PCI DOE timeout interval
(1 second), resolves this issue cleanly.

Per PCIe r6.2 sec 6.30.3, the DOE Busy Bit being cleared does not raise an
interrupt, so polling is the best option in this scenario.

Subsequent code in doe_statemachine_work() and abort paths also wait for up
to 1 PCI DOE timeout interval, so this order of (potential) additional
delay is presumed acceptable.

Subject: [PATCH 0642/2948] devres: Fix page faults when tracing devres from
 unloaded modules

The devres ftrace event logs the name of the devres node, which is often a
function name (e.g., "devm_work_drop") stringified by macros like
devm_add_action. Currently, ftrace stores this name as a string literal
address, which can become invalid when the module containing the string is
unloaded. This results in page faults when ftrace tries to access the name.

This behavior is problematic because the devres ftrace event is designed to
trace resource management throughout a device driver's lifecycle, including
during module unload. The event should be available even after the module
is unloaded to properly diagnose resource issues.

Fix the issue by copying the devres node name into the ftrace ring buffer
using __assign_str(), instead of storing just the address. This ensures
that ftrace can always access the name, even if the module is unloaded.

This change increases the memory usage for each of the ftrace entry by
12-16 bytes assuming the average devres node name is 20 bytes long,
depending on the size of const char *.

Note that this change does not affect anything unless all of following
conditions are met.
- CONFIG_DEBUG_DEVRES is enabled
- ftrace tracing is enabled
- The devres event is enabled in ftrace tracing

Subject: [PATCH 0648/2948] staging: gpib: mark HP82341 driver as broken

The hp82341 driver uses the isapnp_read_byte() call, but it's not
exported for modules at this point in time:

ERROR: modpost: "isapnp_read_byte" [drivers/staging/gpib/hp_82341/hp_82341.ko] undefined!

So mark it as broken for now, it can be fixed and cleaned up later.

Subject: [PATCH 0649/2948] rust: alloc: add `Allocator` trait

Add a kernel specific `Allocator` trait, that in contrast to the one in
Rust's core library doesn't require unstable features and supports GFP
flags.

Subsequent patches add the following trait implementors: `Kmalloc`,
`Vmalloc` and `KVmalloc`.

The compile error is from strncpy refernce in do_test:
	strncpy(str, tool_pmu__event_to_str(ev), sizeof(str));

This behaviour is not observed with GCC version 8, but observed
with GCC version 11 . This is message from gcc for detecting
truncation while using strncpu. Use snprintf instead of strncpy
here to be safe.

Subject: [PATCH 0654/2948] tools/perf/tests: Remove duplicate evlist__delete
 in tests/tool_pmu.c

The testcase for tool_pmu failed in powerpc as below:

 ./perf test -v "Parsing without PMU name"
  8: Tool PMU                                                        :
  8.1: Parsing without PMU name                                      : FAILED!

This happens when parse_events results in either skip or fail
of an event. Because the code invokes evlist__delete(evlist)
and "goto out".

	ret = parse_events(evlist, str, &err);
	if (ret) {
		 evlist__delete(evlist);

But in the "out" section also evlist__delete happens.

	out:
        evlist__delete(evlist);
        return ret;

Hence remove the duplicate evlist__delete from the first path
in the testcase

With the change:
	# ./perf test -v "Parsing without PMU name"
	  8: Tool PMU                                                        :

Subject: [PATCH 0662/2948] dmaengine: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/dma after the previous
conversion commits apart from the wireless drivers to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

Subject: [PATCH 0663/2948] iio: adc: ad7625: add driver

Add a driver for the AD762x and AD796x family of ADCs. These are
pin-compatible devices using an LVDS interface for data transfer,
capable of sampling at rates of 6 (AD7625), 10 (AD7626), and 5
(AD7960/AD7961) MSPS, respectively. They also feature multiple voltage
reference options based on the configuration of the EN1/EN0 pins, which
can be set in the devicetree.

Subject: [PATCH 0664/2948] perf tools: Fix possible compiler warnings in
 hashmap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The hashmap__for_each_entry[_safe] is accessing 'map' as if it's a
pointer.  But it does without parentheses so passing a static hash map
with an ampersand (like &slab_hash below) caused compiler warnings due
to unmatched types.

Subject: [PATCH 0666/2948] perf sched timehist: Add pre-migration wait time
 option

pre-migration wait time is the time that a task unnecessarily spends
on the runqueue of a CPU but doesn't get switched-in there. In terms
of tracepoints, it is the time between sched:sched_wakeup and
sched:sched_migrate_task.

Let's say a task woke up on CPU2, then it got migrated to CPU4 and
then it's switched-in to CPU4. So, here pre-migration wait time is
time that it was waiting on runqueue of CPU2 after it is woken up.

The general pattern for pre-migration to occur is:
sched:sched_wakeup
sched:sched_migrate_task
sched:sched_switch

The sched:sched_waking event is used to capture the wakeup time,
as it aligns with the existing code and only introduces a negligible
time difference.

pre-migrations are generally not useful and it increases migrations.
This metric would be helpful in testing patches mainly related to wakeup
and load-balancer code paths as better wakeup logic would choose an
optimal CPU where task would be switched-in and thereby reducing pre-
migrations.

The sample output(s) when -P or --pre-migrations is used:
=================
           time    cpu  task name                       wait time  sch delay   run time  pre-mig time

Subject: [PATCH 0667/2948] perf evsel: Fix missing inherit + sample read check

It should not clear the inherit bit simply because the kernel doesn't
support the sample read with it.  IOW the inherit bit should be kept
when the sample read is not requested for the event.

Fixes: 90035d3cd876cb71 ("tools/perf: Allow inherit + PERF_SAMPLE_READ when opening events")

Subject: [PATCH 0668/2948] perf test: Delete unused Intel CQM test

As Ian Rogers <irogers@google.com> pointed out, intel-cqm.c is neither
used nor built. It was deleted in the following commit:

commit b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license")

However, it resurfaced soon after in the following commit:

commit 5c9295bfe6f5 ("perf tests: Remove Intel CQM perf test")

It should be deleted once and for all.

Subject: [PATCH 0669/2948] perf arm-spe: Rename
 arm_spe__synth_data_source_generic()

The arm_spe__synth_data_source_generic() function is invoked when the
tool detects that CPUs do not support data source packets and falls back
to synthesizing only the memory level.

Rename it to arm_spe__synth_memory_level() for better reflecting its
purpose.

Subject: [PATCH 0672/2948] perf arm-spe: Use metadata to decide the data
 source feature

Use the info in the metadata to decide if the data source feature is
supported. The CPU MIDR must be in the CPU list for the common data
source encoding.

For the metadata version 1, it doesn't include info for MIDR. In this
case, due to absent info for making decision, print out warning to
remind users to upgrade tool and returns false.

For clusters of the following type, i_blocks are decremented by 1 and
i_compr_blocks are incremented by 7 in release_compress_blocks, while
updates to i_blocks and i_compr_blocks are skipped in reserve_compress_blocks.

raw node:
D D D D D D D D
after compress:
C D D D D D D D
after reserve:
C D D D D D D D

Let's update i_blocks and i_compr_blocks properly in reserve_compress_blocks.

Subject: [PATCH 0679/2948] f2fs: fix f2fs_bug_on when uninstalling filesystem
 call f2fs_evict_inode.

creating a large files during checkpoint disable until it runs out of
space and then delete it, then remount to enable checkpoint again, and
then unmount the filesystem triggers the f2fs_bug_on as below:

The root cause is: creating large files during disable checkpoint
period results in not enough free segments, so when writing back root
inode will failed in f2fs_enable_checkpoint. When umount the file
system after enabling checkpoint, the root inode is dirty in
f2fs_evict_inode function, which triggers BUG_ON. The steps to
reproduce are as follows:

dd if=/dev/zero of=f2fs.img bs=1M count=55
mount f2fs.img f2fs_dir -o checkpoint=disable:10%
dd if=/dev/zero of=big bs=1M count=50
sync
rm big
mount -o remount,checkpoint=enable f2fs_dir
umount f2fs_dir

Let's redirty inode when there is not free segments during checkpoint
is disable.

Above issue happens as the biset of the f2fs file system is not

To address above issue just register "f2fs_fs_type" at the last in
init_f2fs_fs(). Ensure that all f2fs file system resources are
initialized.

+====================
+AD7625 driver
+====================
+
+ADC driver for Analog Devices Inc. AD7625, AD7626, AD7960, and AD7961
+devices. The module name is ``ad7625``.
+
+Supported devices
+=================
+
+The following chips are supported by this driver:
+
+* `AD7625 <https://www.analog.com/AD7625>`_
+* `AD7626 <https://www.analog.com/AD7626>`_
+* `AD7960 <https://www.analog.com/AD7960>`_
+* `AD7961 <https://www.analog.com/AD7961>`_
+
+The driver requires use of the Pulsar LVDS HDL project:
+
+* `Pulsar LVDS HDL <http://analogdevicesinc.github.io/hdl/projects/pulsar_lvds/index.html>`_
+
+To trigger conversions and enable subsequent data transfer, the devices
+require coupled PWM signals with a phase offset.
+
+Supported features
+==================
+
+Conversion control modes
+------------------------
+
+The driver currently supports one of two possible LVDS conversion control methods.
+
+Echoed-Clock interface mode

+
+Reference voltage
+-----------------
+
+Three possible reference voltage sources are supported:
+
+- Internal reference (only available on AD7625 and AD7626)
+- External reference and internal buffer
+- External reference
+
+The source is determined by the device tree. If ``ref-supply`` is present, then
+the external reference is used. If ``refin-supply`` is present, then the internal
+buffer is used. If neither is present, then the internal reference is used.
+
+Unimplemented features
+----------------------
+
+- Self-clocked mode
+
+
+Device attributes
+=================
+
+The AD762x is a fully-differential ADC and has the following attributes:
+
++---------------------------------------+--------------------------------------------------------------+
+| Attribute                             | Description                                                  |
++=======================================+==============================================================+
+| ``scale``                             | Scale factor to convert raw value from buffered reads to mV. |
++---------------------------------------+--------------------------------------------------------------+
+
+
+Device buffers
+==============
+
+This driver supports IIO triggered buffers.
+
+See :doc:`iio_devbuf` for more information.

Subject: [PATCH 0689/2948] iio: light: veml6035: fix read_avail in no_irq case
 for veml6035

The iio_info is identical for veml6030 and veml6035. Moreover,
veml6035_info_no_irq is missing the initialization of the read_avail
member, which is actually a bug if no irq is provided.

Instead of adding the missing initialization, remove the device-specific
iio_info and use the existing one for the veml6030.

which makes it suitable to be supported by the same bindings.

The veml7700 contains the same sensor as the veml6030 in a different
package with no interrupt line and no pin to select the I2C address.

To handle the lack of the interrupt line and profit from the existing
support for the veml6030, add a specific iio_chan_spec with no
(num_)event_spec(s), and register the device's info from the
veml6030_info_no_irq struct.

 inter-measurement period support

Expose the IIO_CHAN_INFO_SAMP_FREQ attribute as a way to configure the
inter-measurement period for both the IIO_DISTANCE and IIO_LIGHT
channels. The inter-measurement period must be given in milihertz.

Subject: [PATCH 0694/2948] iio: light: vl6180: Added Interrupt support for
 single shot access

The interrupts are serviced in the `vl6180_measure` function when the
irq_handler signals that the reading is complete. We now can read
asynchronously if `client->irq` is set.

Subject: [PATCH 0695/2948] iio: light: vl6180: Add support for Continuous Mode

Added support for getting continuous readings from vl6180 using
triggered buffer approach. The continuous mode can be enabled by enabling
the buffer. Also added a trigger and appropriate checks to see that it is
used with this device.

Subject: [PATCH 0696/2948] iio: light: rpr0521: Use generic
 iio_pollfunc_store_time()

The custom rpr0521_trigger_consumer_store_time() is registered as trigger
handler in the devm_iio_triggered_buffer_setup() function. This function
is called from the calling of the iio_trigger_poll() used in the
sysfs/hrt triggers and it is not used anywhere else in this driver.

The irq handler of the driver is the rpr0521_drdy_irq_handler() which
saves the timestamp and then wakes the irq thread. The irq thread is
the rpr0521_drdy_irq_thread() function which checks if the irq came
from the sensor and wakes up the trigger threaded handler through
iio_trigger_poll_nested() or returns IRQ_NONE in case the irq didn't
come from this sensor.

This means that in the current driver, you can't reach the
rpr0521_trigger_consumer_store_time() when the device's irq is
triggered. This means that the extra check of iio_trigger_using_own()
is redundant since it will always be false so the general
iio_pollfunc_store_time() can be used.

Subject: [PATCH 0697/2948] Input: switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/input/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

While touching these files, make indention of the struct initializer
consistent in a few drivers.

The power supply core never modifies the resist table.

 power_supply_config
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To inhibit wakeup users currently have to use dedicated functions to
register the power supply: {,devm_}power_supply_register_no_ws().
This is inconsistent to other runtime settings which can be configured
through struct power_supply_config.
It's also not obvious what _no_ws() is meant to mean.

Extend power_supply_config to also be able to inhibit the wakeup source.

The same functionality is available through
power_supply_config::no_wakeup_source, which is more idiomatic.
All users of the old API have been converted.

Also remove the argument "ws" from __power_supply_register(),
as it is now always "true".

Subject: [PATCH 0713/2948] power: supply: core: Remove might_sleep() from
 power_supply_put()

The put_device() call in power_supply_put() may call
power_supply_dev_release(). The latter function does not sleep so
power_supply_put() doesn't sleep either. Hence, remove the might_sleep()
call from power_supply_put(). This patch suppresses false positive
complaints about calling a sleeping function from atomic context if
power_supply_put() is called from atomic context.

Subject: [PATCH 0716/2948] rust: alloc: implement `ReallocFunc`

`ReallocFunc` is an abstraction for the kernel's realloc derivates, such
as `krealloc`, `vrealloc` and `kvrealloc`.

All of the named functions share the same function signature and
implement the same semantics. The `ReallocFunc` abstractions provides a
generalized wrapper around those, to trivialize the implementation of
`Kmalloc`, `Vmalloc` and `KVmalloc` in subsequent patches.

Implement `Allocator` for `Kmalloc`, the kernel's default allocator,
typically used for objects smaller than page size.

All memory allocations made with `Kmalloc` end up in `krealloc()`.

It serves as allocator for the subsequently introduced types `KBox` and
`KVec`.

`Allocator`s, such as `Kmalloc`, will be used by e.g. `Box` and `Vec` in
subsequent patches, and hence this dependency propagates throughout the
whole kernel.

Add the `allocator_test` module that provides an empty implementation
for all `Allocator`s in the kernel, such that we don't break the
`rusttest` make target in subsequent patches.

Subject: [PATCH 0720/2948] rust: alloc: implement `Vmalloc` allocator

Implement `Allocator` for `Vmalloc`, the kernel's virtually contiguous
allocator, typically used for larger objects, (much) larger than page
size.

All memory allocations made with `Vmalloc` end up in `vrealloc()`.

Implement `Allocator` for `KVmalloc`, an `Allocator` that tries to

`vmalloc`.

All memory allocations made with `KVmalloc` end up in
`kvrealloc_noprof()`; all frees in `kvfree()`.

Subject: [PATCH 0723/2948] rust: alloc: implement kernel `Box`

`Box` provides the simplest way to allocate memory for a generic type
with one of the kernel's allocators, e.g. `Kmalloc`, `Vmalloc` or
`KVmalloc`.

In contrast to Rust's `Box` type, the kernel `Box` type considers the
kernel's GFP flags for all appropriate functions, always reports
allocation failures through `Result<_, AllocError>` and remains
independent from unstable features.

Subject: [PATCH 0725/2948] rust: alloc: remove extension of std's `Box`

Now that all existing `Box` users were moved to the kernel `Box` type,
remove the `BoxExt` extension and all other related extensions.

Subject: [PATCH 0727/2948] rust: alloc: introduce `ArrayLayout`

When allocating memory for arrays using allocators, the `Layout::array`
function is typically used. It returns a result, since the given size
might be too big. However, `Vec` and its iterators store their allocated
capacity and thus they already did check that the size is not too big.

The `ArrayLayout` type provides this exact behavior, as it can be
infallibly converted into a `Layout`. Instead of a `usize` capacity,
`Vec` and other similar array-storing types can use `ArrayLayout`
instead.

Subject: [PATCH 0728/2948] rust: alloc: implement kernel `Vec` type

`Vec` provides a contiguous growable array type with contents allocated
with the kernel's allocators (e.g. `Kmalloc`, `Vmalloc` or `KVmalloc`).

In contrast to Rust's stdlib `Vec` type, the kernel `Vec` type considers
the kernel's GFP flags for all appropriate functions, always reports
allocation failures through `Result<_, AllocError>` and remains
independent from unstable features.

[ This patch starts using a new unstable feature, `inline_const`, but
  it was stabilized in Rust 1.79.0, i.e. the next version after the
  minimum one, thus it will not be an issue. - Miguel ]

+/// [`Kmalloc`], [`Vmalloc`] or [`KVmalloc`]), written `Vec<T, A>`.
+///
+/// For non-zero-sized values, a [`Vec`] will use the given allocator `A` for its allocation. For
+/// the most common allocators the type aliases [`KVec`], [`VVec`] and [`KVVec`] exist.
+///
+/// For zero-sized types the [`Vec`]'s pointer must be `dangling_mut::<T>`; no memory is allocated.
+///
+/// Generally, [`Vec`] consists of a pointer that represents the vector's backing buffer, the
+/// capacity of the vector (the number of elements that currently fit into the vector), its length
+/// (the number of elements that are currently stored in the vector) and the `Allocator` type used
+/// to allocate (and free) the backing buffer.
+///
+/// A [`Vec`] can be deconstructed into and (re-)constructed from its previously named raw parts
+/// and manually modified.
+///
+/// [`Vec`]'s backing buffer gets, if required, automatically increased (re-allocated) when elements
+/// are added to the vector.
+///
+/// # Invariants
+///
+/// - `self.ptr` is always properly aligned and either points to memory allocated with `A` or, for
+///   zero-sized types, is a dangling, well aligned pointer.
+///
+/// - `self.len` always represents the exact number of elements stored in the vector.
+///
+/// - `self.layout` represents the absolute number of elements that can be stored within the vector
+///   without re-allocation. For ZSTs `self.layout`'s capacity is zero. However, it is legal for the
+///   backing buffer to be larger than `layout`.
+///
+/// - The `Allocator` type `A` of the vector is the exact same `Allocator` type the backing buffer
+///   was allocated with (and must be freed with).

Subject: [PATCH 0729/2948] rust: alloc: implement `IntoIterator` for `Vec`

Implement `IntoIterator` for `Vec`, `Vec`'s `IntoIter` type, as well as
`Iterator` for `IntoIter`.

`Vec::into_iter` disassembles the `Vec` into its raw parts; additionally,
`IntoIter` keeps track of a separate pointer, which is incremented
correspondingly as the iterator advances, while the length, or the count
of elements, is decremented.

This also means that `IntoIter` takes the ownership of the backing
buffer and is responsible to drop the remaining elements and free the
backing buffer, if it's dropped.

Subject: [PATCH 0730/2948] rust: alloc: implement `collect` for `IntoIter`

Currently, we can't implement `FromIterator`. There are a couple of
issues with this trait in the kernel, namely:

  - Rust's specialization feature is unstable. This prevents us to
    optimize for the special case where `I::IntoIter` equals `Vec`'s
    `IntoIter` type.
  - We also can't use `I::IntoIter`'s type ID either to work around this,
    since `FromIterator` doesn't require this type to be `'static`.
  - `FromIterator::from_iter` does return `Self` instead of
    `Result<Self, AllocError>`, hence we can't properly handle allocation
    failures.
  - Neither `Iterator::collect` nor `FromIterator::from_iter` can handle
    additional allocation flags.

Instead, provide `IntoIter::collect`, such that we can at least convert
`IntoIter` into a `Vec` again.

Subject: [PATCH 0736/2948] rust: alloc: implement `contains` for `Flags`

Provide a simple helper function to check whether given flags do
contain one or multiple other flags.

This is used by a subsequent patch implementing the Cmalloc `Allocator`
to check for __GFP_ZERO.

Subject: [PATCH 0737/2948] rust: alloc: implement `Cmalloc` in module
 allocator_test

So far the kernel's `Box` and `Vec` types can't be used by userspace
test cases, since all users of those types (e.g. `CString`) use kernel
allocators for instantiation.

In order to allow userspace test cases to make use of such types as
well, implement the `Cmalloc` allocator within the allocator_test module
and type alias all kernel allocators to `Cmalloc`. The `Cmalloc`
allocator uses libc's `realloc()` function as allocator backend.

Subject: [PATCH 0738/2948] rust: str: test: replace `alloc::format`

The current implementation of tests in str.rs use `format!` to format
strings for comparison, which, internally, creates a new `String`.

In order to prepare for getting rid of Rust's alloc crate, we have to
cut this dependency. Instead, implement `format!` for `CString`.

Note that for userspace tests, `Kmalloc`, which is backing `CString`'s
memory, is just a type alias to `Cmalloc`.

Before we remove Rust's alloc crate, rewrite the module comment in
alloc.rs to avoid a rustdoc warning.

Besides that, the module comment in alloc.rs isn't correct anymore,
we're no longer extending Rust's alloc crate.

Subject: [PATCH 0740/2948] kbuild: rust: remove the `alloc` crate and
 `GlobalAlloc`

Now that we have our own `Allocator`, `Box` and `Vec` types we can remove
Rust's `alloc` crate and the `new_uninit` unstable feature.

Also remove `Kmalloc`'s `GlobalAlloc` implementation -- we can't remove
this in a separate patch, since the `alloc` crate requires a
`#[global_allocator]` to set, that implements `GlobalAlloc`.

Subject: [PATCH 0741/2948] MAINTAINERS: add entry for the Rust `alloc` module

Add maintainers entry for the Rust `alloc` module.

Currently, this includes the `Allocator` API itself, `Allocator`
implementations, such as `Kmalloc` or `Vmalloc`, as well as the kernel's
implementation of the primary memory allocation data structures, `Box`
and `Vec`.

bfa_get_pciids and bfa_cfg_get_min aren't called anywhere; remove them
together with the bfa_pciid_s used by bfa_get_pciids.

(Build tested, I don't have the card)

Subject: [PATCH 0748/2948] pinctrl: PINCTRL_K230 should depend on ARCH_CANAAN

The Canaan Kendryte K230 pin controller is only present on Canaan
Kendryte K230 SoCs.  Hence add a dependency on ARCH_CANAAN, to prevent
asking the user about this driver when configuring a kernel without
Canaan Kendryte series SoC platform support.

Subject: [PATCH 0750/2948] scsi: hisi_sas: Create trigger_dump at the end of
 the debugfs initialization

In the current debugfs initialization process, the interface
trigger_dump is created first, and then the dump directory is created to
store the register dump information.

The issue is that after the trigger_dump interface is created, users can
access the interface to trigger dump and call
debugfs_create_files_v3_hw().  In debugfs_create_files_v3_hw(), if
.debugfs_dump_dentry is NULL, the file for storing dump information is
created under /sys/kernel/debug, and the memory and information cannot
be released after the driver is uninstalled.

Therefore, the creation of the trigger_dump interface is placed at the
end of debugfs initialization.

Subject: [PATCH 0752/2948] scsi: hisi_sas: Enable all PHYs that are not
 disabled by user during controller reset

For the controller reset operation(such as FLR or clear nexus ha in SCSI
EH), we will disable all PHYs and then enable PHY based on the
hisi_hba->phy_state obtained in hisi_sas_controller_reset_prepare(). If
the device is removed before controller reset or the PHY is not attached
to any device in directly attached scenario, the corresponding bit of
phy_state is not set. After controller reset done, the PHY is disabled.
The device cannot be identified even if user reconnect the disk.

Therefore, for PHYs that are not disabled by user, hisi_sas_phy_enable()
needs to be executed even if the corresponding bit of phy_state is not
set.

In commit 89954f024c3a ("scsi: hisi_sas: Ensure all enabled PHYs up

operations and wait for PHYs come up. However, for some directly
attached SATA disks, the PHY not come up after a timeout period and the
hardware is not ready.  At this time, we should get the latest PHY
hardware state, if the new PHY state is not ready but the old PHY state
is ready, call work HISI_PHYE_LINK_RESET to give it another chance to
phyup.

Subject: [PATCH 0754/2948] scsi: hisi_sas: Check usage count only when the
 runtime PM status is RPM_SUSPENDING

Users can suspend the machine with 'echo disk > /sys/power/state', but
the suspend will fail because the SAS controller cannot be suspended:

[root@localhost ~]# echo freeze > /sys/power/state
-bash: echo: write error: Device or resource busy

[15104.283542] hisi_sas_v3_hw 0000:30:04.0: PM: failed to suspend async: error -16

The problem is that when the ->runtime_suspend() callback
suspend_v3_hw() is executing, the current runtime PM status is
RPM_ACTIVE and the usage count of the controller is not 0, so return
immediately.

To fix it, Check the device usage count only when the runtime PM status
is RPM_SUSPENDING.

This is because in the hisi_sas driver, both the hardware interrupt
handler and the interrupt thread are executed on the same CPU. In the
performance test scenario, function irq_wait_for_interrupt() will always
return 0 if lots of interrupts occurs and the CPU will be continuously
consumed. As a result, the CPU cannot run the watchdog thread. When the
watchdog time exceeds the specified time, call trace occurs.

To fix it, add cond_resched() to execute the watchdog thread.

[ 4682.868084][  C129] Disabling IRQ #134

When the IRQ management layer processes each hardware interrupt, if the
return value of the interrupt handler is IRQ_WAKE_THREAD, it will wake
up the handler thread for this interrupt action and set IRQTF_RUNTHREAD
flag, wait for the interrupt handling thread to clear the
IRQTF_RUNTHREAD flag after execution. Later in note_interrupt(), use
irq_count to count hardware interrupts and irqs_unhandled to count
interrupts for which no thread handler is responsible. When irq_count
reaches 100000 and irqs_unhandled reaches 99000, irq will be disabled.

In the performance test scenario, I/O completion hardware interrupts are
continuously and quickly generated. As a result, the interrupt
processing thread is cyclically called in irq_thread() and does not
exit, this affects the response of the interrupt thread to the hardware
interrupt and causes irqs_unhandled to grow to 99000. Finally, the irq
is disabled.

Therefore, default enable interrupt coalescing to reduce the generation
of hardware interrupts, this helps interrupt processing threads to stop
calling in irq_thread().

For interrupt coalescing, according to the actual performance test, set
the count of CQ entries to 10 and the interrupt coalescing timeout
period to 10us based on the actual performance test.

Before and after interrupt coalescing is enabled, the 4K read/write
performance is improved by about 3%, and the 256K read/write performance
is basically the same.

Subject: [PATCH 0757/2948] scsi: hisi_sas: Update disk locked timeout to 7
 seconds

The SATA disk will be locked after the disk sends the DMA Setup frame
until all data frame transmission is completed. The
CFG_ICT_TIMER_STEP_TRSH register is used for sata disk to configure the
step size of the timer which records the time when the disk is
locked. The unit is 1us and the default step size is 150ms. If the disk
is locked for more than 7 timer steps, the io to be sent to the disk
will end abnormally.

The current timeout is only about 1 second, it is easy to trigger IO
abnormal end when the SATA hard disk returns data slowly. Adjust the
timeout to 7 seconds based on ERC time of most disks.

Spec says at least 5us between two H2D FIS when do soft reset, but be
generous and sleep for about 1ms.

Subject: [PATCH 0759/2948] scsi: hisi_sas: Update v3 hw STP_LINK_TIMER setting

At present, it is found that some SATA HDD disks may continue to return
the HOLD primitive for more than 500ms when they are busy writing data,
which is more likely to trigger an STP link timeout exception. Now
Modify STP link timer from 500ms to the maximum value of 1.048575s.

Subject: [PATCH 0760/2948] scsi: hisi_sas: Create all dump files during
 debugfs initialization

For the current debugfs of hisi_sas, after user triggers dump, the
driver allocate memory space to save the register information and create
debugfs files to display the saved information. In this process, the
debugfs files created after each dump.

Therefore, when the dump is triggered while the driver is unbind, the
following hang occurs:

To fix this issue, create all directories and files during debugfs
initialization. In this way, the driver only needs to allocate memory
space to save information each time the user triggers dumping.

Subject: [PATCH 0761/2948] scsi: hisi_sas: Add latest_dump for the debugfs
 dump

Before that, after the user triggers the dump, the latest dump
information can be viewed in the directory with the maximum number in
the dump directory.

After this series patch, the driver creates all debugfs directories and
files during initialization. Therefore, users cannot know the directory
where the latest dump information is stored. So, add latest_dump file to
notify users where the latest dump information is stored.

Subject: [PATCH 0762/2948] dt-bindings: pinctrl: samsung: Fix interrupt
 constraint for variants with fallbacks

Commit 904140fa4553 ("dt-bindings: pinctrl: samsung: use Exynos7
fallbacks for newer wake-up controllers") added
samsung,exynos7-wakeup-eint fallback to some compatibles, so the
intention in the if:then: conditions was to handle the cases:

1. Single Exynos7 compatible or Exynos5433+Exynos7 or
   Exynos7885+Exynos7: only one interrupt

2. Exynos850+Exynos7: no interrupts

This was not implemented properly however and if:then: block matches
only single Exynos5433 or Exynos7885 compatibles, which do not exist in
DTS anymore, so basically is a no-op and no enforcement on number of
interrupts is made by the binding.

Fix the if:then: condition so interrupts in the Exynos5433 and
Exynos7885 wake-up pin controller will be properly constrained.

Fixes: 904140fa4553 ("dt-bindings: pinctrl: samsung: use Exynos7 fallbacks for newer wake-up controllers")

 in error path for fw_node

An error path was introduced without including the required call to
of_node_put() to decrement the node's refcount and avoid leaking memory.
If the call to kzalloc() for 'mgmt' fails, the probe returns without
decrementing the refcount.

Use the automatic cleanup facility to fix the bug and protect the code
against new error paths where the call to of_node_put() might be missing
again.

residue is never initialized in this function and it is not used outside
of an error print. Just remove it altogether, as it is likely not
necessary in this function, as this same exact statement in present in
fmh_gpib_dma_read().

Subject: [PATCH 0771/2948] staging: olpc_dcon: Remove driver marked as broken
 since 2022

Andres Salomon contributed this driver in 2010.

The following reasons lead to the removal:
- This driver generates maintenance workload
- Kconfig still depends on BROKEN since 2022.

Subject: [PATCH 0772/2948] staging: gpib: Remove unused value

The variable `complement_count` is assigned a value which is again
overwritten in the next statement.
Fix this by removing the first value assigning statement

This issue was reported by Coverity Scan.
Report:
CID 1600790: (#1 of 1): Unused value (UNUSED_VALUE)
assigned_value: Assigning value from length to complement_count here,
but that stored value is overwritten before it can be used.

Subject: [PATCH 0773/2948] usb: typec: ucsi: Do not call ACPI _DSM method for
 UCSI read operations

ACPI _DSM methods are needed only for UCSI write operations and for reading
CCI during RESET_PPM operation. So, remove _DSM calls from other places.
While there, remove the Zenbook quirk also since the default behavior
now aligns with the Zenbook quirk. With this change, GET_CONNECTOR_STATUS
returns at least 6 seconds faster than before in Arrowlake-S platforms.

Subject: [PATCH 0778/2948] usb: gadget: uvc: configfs: Add frame-based frame
 format support

Add support for frame-based frame format, which can be used to support
multiple formats like H264 or H265, in addition to MJPEG and YUV frames.

The frame-based format is set to H264 by default, but it can be updated
to other formats by modifying the GUID through the guid configfs
attribute. Different structures are used for all three formats, as
H264 has a different structure compared to MJPEG and uncompressed
formats. These structures will be passed to the frame make function
based on the active format, using a common frame structure with
additional parameters needed only for frame-based formats. These
parameters are handled at runtime in the UVC driver.

Subject: [PATCH 0780/2948] mailbox, remoteproc: k3-m4+: fix compile testing

The k3-m4 remoteproc driver was merged with incorrect dependencies.
Despite multiple people trying to fix this, the version 6.12-rc2
remains broken and causes a build failure with CONFIG_TI_SCI_PROTOCOL=m
when the driver is built-in.

arm-linux-gnueabi-ld: drivers/remoteproc/ti_k3_m4_remoteproc.o: in function `k3_m4_rproc_probe':
ti_k3_m4_remoteproc.c:(.text.k3_m4_rproc_probe+0x76): undefined reference to `devm_ti_sci_get_by_phandle'

Fix the dependency again to make it work in all configurations.
The 'select OMAP2PLUS_MBOX' no longer matches what the other drivers
dependencies. The link failure can be avoided with a simple 'depends
do, so turn that into the same 'depends' to ensure we get no circular
on TI_SCI_PROTOCOL', but the extra COMPILE_TEST alternative is what
we use elsehwere. On the other hand, building for OMAP2PLUS makes
no sense since the hardware only exists on K3.

calculate cosumed free segments later, and return ENOSPC earlier to
avoid run out of free segment during block allocation.

Subject: [PATCH 0782/2948] PCI: endpoint: Introduce pci_epc_mem_map()/unmap()

Some endpoint controllers have requirements on the alignment of the
controller physical memory address that must be used to map a RC PCI
address region. For instance, the endpoint controller of the RK3399 SoC
uses at most the lower 20 bits of a physical memory address region as
the lower bits of a RC PCI address region. For mapping a PCI address
region of size bytes starting from pci_addr, the exact number of
address bits used is the number of address bits changing in the address
range [pci_addr..pci_addr + size - 1]. For this example, this creates
the following constraints:
1) The offset into the controller physical memory allocated for a
   mapping depends on the mapping size *and* the starting PCI address
   for the mapping.
2) A mapping size cannot exceed the controller windows size (1MB) minus
   the offset needed into the allocated physical memory, which can end
   up being a smaller size than the desired mapping size.

Handling these constraints independently of the controller being used
in an endpoint function driver is not possible with the current EPC
API as only the ->align field in struct pci_epc_features is provided
but used for BAR (inbound ATU mappings) mapping only. A new API is
needed for function drivers to discover mapping constraints and handle
non-static requirements based on the RC PCI address range to access.

Introduce the endpoint controller operation ->align_addr() to allow
the EPC core functions to obtain the size and the offset into a
controller address region that must be allocated and mapped to access
a RC PCI address region. The size of the mapping provided by the
align_addr() operation can then be used as the size argument for the
function pci_epc_mem_alloc_addr() and the offset into the allocated
controller memory provided can be used to correctly handle data
transfers. For endpoint controllers that have PCI address alignment
constraints, the align_addr() operation may indicate upon return an
effective PCI address mapping size that is smaller (but not 0) than the
requested PCI address region size.

The controller ->align_addr() operation is optional: controllers that
do not have any alignment constraints for mapping RC PCI address regions
do not need to implement this operation. For such controllers, it is
always assumed that the mapping size is equal to the requested size of
the PCI region and that the mapping offset is 0.

The function pci_epc_mem_map() is introduced to use this new controller
operation (if it is defined) to handle controller memory allocation and
mapping to a RC PCI address region in endpoint function drivers.

This function first uses the ->align_addr() controller operation to
determine the controller memory address size (and offset into) needed
for mapping an RC PCI address region. The result of this operation is
used to allocate a controller physical memory region using
pci_epc_mem_alloc_addr() and then to map that memory to the RC PCI
address space with pci_epc_map_addr().

Since ->align_addr() () may indicate that not all of a RC PCI address
region can be mapped, pci_epc_mem_map() may only partially map the RC
PCI address region specified. It is the responsibility of the caller
(an endpoint function driver) to handle such smaller mapping by
repeatedly using pci_epc_mem_map() over the desried PCI address range.

The counterpart of pci_epc_mem_map() to unmap and free a mapped
controller memory address region is pci_epc_mem_unmap().

Both functions operate using the new struct pci_epc_map data structure.
This new structure represents a mapping PCI address, mapping effective
size, the size of the controller memory needed for the mapping as well
as the physical and virtual CPU addresses of the mapping (phys_base and
virt_base fields). For convenience, the physical and virtual CPU
addresses within that mapping to use to access the target RC PCI address
region are also provided (phys_addr and virt_addr fields).

Endpoint function drivers can use struct pci_epc_map to access the
mapped RC PCI address region using the ->virt_addr and ->pci_size
fields.

Subject: [PATCH 0784/2948] PCI: endpoint: test: Use pci_epc_mem_map/unmap()

Modify the endpoint test driver to use the functions pci_epc_mem_map()
and pci_epc_mem_unmap() for the read, write and copy tests. For each
test case, the transfer (dma or mmio) are executed in a loop to ensure
that potentially partial mappings returned by pci_epc_mem_map() are
correctly handled.

Subject: [PATCH 0786/2948] pinctrl: th1520: Fix potential null pointer
 dereference on func

The initialization of muxtype deferences pointer func before func
is sanity checked with a null pointer check, hence we have a null
pointer deference issue. Fix this by only deferencing func with
the assignment to muxtype after func has been null pointer checked.

Use a fallback compatible since for especially for generic

U-Boot actually uses a generic 6030/32 function to enable the
charger.

Subject: [PATCH 0788/2948] power: supply: initial support for TWL6030/32

Add a driver for the charger in the TWL6030/32. For now it does not report
much in sysfs but parameters are set up for USB, charging is enabled with
the specified parameters. It stops charging when full and also restarts
charging.
This prevents ending up in a system setup where you run out of battery
although a charger is plugged in after precharge completed.

Battery voltage behavior was checked via the GPADC.

Subject: [PATCH 0789/2948] dt-bindings: reset: syscon-reboot: Add reg property

The syscon-reboot binding used 'offset' for historical reasons. Having a
reg property is appropriate when these nodes are children of a MMIO bus.
Add a reg property and modify the constraints so that one of 'reg' or
'offset' is expected.

Subject: [PATCH 0792/2948] perf x86/topdown: Make topdown metrics comparators
 be symmetric

The commit "3b5edc0421e2 (perf x86/topdown: Don't move topdown metric
 events in group)" modifies topdown metrics comparator to move topdown
metrics events which are not in same group with previous event. But it
just modifies the 2nd comparator and causes the comparators become
asymmetric.

Thus modify the 1st topdown metrics comparator and make the two
comparators be symmetric, and refine the comments as well.

Subject: [PATCH 0793/2948] perf x86/topdown: Refine helper
 arch_is_topdown_metrics()

Leverage the existed function perf_pmu__name_from_config() to check if
an event is topdown metrics event. perf_pmu__name_from_config() goes
through the defined formats and figures out the config of pre-defined
topdown events.

This avoids to figure out the config of topdown pre-defined events with
hard-coded format strings "event=" and "umask=" and provides more
flexibility.

Since commit ("power: supply: Drop use_cnt check from power_supply_property_is_writeable()"),
this function does not check use_cnt anymore, making it unsuitable for
general usage. As it is only used by the psy core anyways, remove it
from the public header and unexport it to avoid misusage.

Subject: [PATCH 0800/2948] power: supply: rt9471: Use IC status regfield to

Use IC status regfield to rewrite the 'get_staus' function. The original
one cannot cover some special scenario like as charger OTG or JEITA case.

Subject: [PATCH 0801/2948] power: supply: rk817: stop updating info in suspend

The driver has a thread that checks the battery every 8 seconds. Stop
this thread during device suspend as while the device is suspended not
all values seem to be read correctly (such as battery voltage). The
resume function triggers the thread to start again.

Subject: [PATCH 0802/2948] power: supply: rk817: Update battery capacity
 calibration

The battery capacity calibration function continues to be a source of
bugs for end users, especially when coming out of suspend. This occurs
when the device has incorrect readings for voltage, and causes the
current code to set fully charged capacity incorrectly.

Add checks to ensure we don't attempt a capacity calibration when we
have invalid voltage values or no battery present, and remove the code
that attempts to automatically set the fully charged capacity in lieu of
making the value writeable. This way userspace is able to adjust the
fully charged capacity for a degraded battery.

Subject: [PATCH 0803/2948] usb: require FMODE_WRITE for usbdev_mmap()

usbdev_mmap() creates VMAs which can only be used through
usbdev_do_ioctl(), which requires FMODE_WRITE; so usbdev_mmap() is only
useful with FMODE_WRITE.

On typical Linux systems, files at /dev/bus/usb/*/* are mode 0664, so
UIDs without any special privileges can't use usbdev_do_ioctl(), but
they can still execute the usbdev_mmap() codepath.

Check for FMODE_WRITE in usbdev_mmap() to reduce attack surface a little
bit.

Subject: [PATCH 0806/2948] usb: typec: Add attribute file showing the USB
 Modes of the partner

This attribute file shows the supported USB modes (USB 2.0,
USB 3.0 and USB4) of the partner, and the currently active
mode.

The active mode is determined primarily by checking the
speed of the enumerated USB device. When USB Power Delivery
is supported, the active USB mode should be always the mode
that was used with the Enter_USB Message, regardless of the
result of the USB enumeration. The port drivers can
separately assign the mode with a dedicated API.

If USB Power Delivery Identity is supplied for the partner
device, the supported modes are extracted from it.

Subject: [PATCH 0808/2948] usb: typec: ucsi: Add support for the partner USB
 Modes

UCSI does not share the contents of the Enter_USB Message
that was used, so the active mode still has to be always
determined from the enumerated USB device. However, after
UCSI v2.0 it is possible to check separately is USB4 the
active mode.

So with USB2 and USB3 the mode is always determined from the
result of the USB enumeration, and when USB4 USB Mode is
active, UCSI driver can assign the mode directly.

Subject: [PATCH 0809/2948] usb: gadget: uvc: wake pump everytime we update the
 free list

Since the req_free list will updated if enqueuing one request was not
possible it will be added back to the free list. With every available
free request in the queue it is a valid case for the pump worker to use
it and continue the pending bufferdata into requests for the req_ready
list.

Subject: [PATCH 0810/2948] usb: gadget: uvc: only enqueue zero length requests
 in potential underrun

The complete handler will at least be called after 16 requests have
completed, but will still handle all finisher requests. Since we have
to maintain a costant filling in the isoc queue we ensure this by
adding zero length requests.

By counting the amount enqueued requests we can ensure that the queue is
never underrun and only need to get active if the queue is running
critical. This patch is setting 32 as the critical level, which
is twice the request amount that is needed to create interrupts.

To properly solve the amount of zero length requests that needs to
be held in the hardware after one interrupt needs to be measured
and depends on the runtime of the first enqueue run after the interrupt
triggered. For now we just use twice the amount of requests between an
interrupt.

Subject: [PATCH 0811/2948] usb: gadget: uvc: rework to enqueue in pump worker
 from encoded queue

We install an kthread with pfifo priority that is iterating over all
prepared requests and keeps the isoc queue busy. This way it will be
scheduled with the same priority as the interrupt handler.

As the kthread is triggered with video_enable it will immediately
queue some zero length requests into the hw if there is no buffer data
available. It also watches the level of needed zero length requests in
the hardware not to fall under the UVCG_REQ_MAX_ZERO_COUNT threshold.
This way we can drop the function uvc_video_ep_queue_initial_requests
entirely.

By using the kthread to do the actual request handling the interrupt
handler will not be running into the time consuming and eventually
locking work of actually enqueueing the requests back into its own
pipeline. This work can now even be scheduled on another cpu.

Subject: [PATCH 0813/2948] usb: gadget: uvc: set req_size and n_requests based
 on the frame interval

This patch is removing the initial imprecise and limited calculation of
requests needed to be used from the queue_setup callback. It instead
introduces the uvc_video_prep_requests function which is called
immediately before the request allocation.

With the information of the usb frame interval length it is possible to
calculate the number of requests needed during one frame duration.

Based on the calculated number of requests and the imagesize we
calculate the actual size per request. This calculation has the benefit
that the frame data is equally distributed over all allocated requests.

When the req_size is not in the range for the actually configured
max_req_size configured for the overall bandwidth we fallback
to use the max_req_size instead.

Since this calculations are only important for isoc transfers we just
use max_request_size for bulk and skip it.

As video->req_size will be recalculated on every video_enable resetting
it to 0 is not necessary anymore.

Subject: [PATCH 0814/2948] usb: gadget: uvc: set req_length based on payload
 by nreqs instead of req_size

Compressed formats generate content depending amount of data that is set
in the vb2 buffer by the payload_size. When streaming those formats it
is better to scatter that smaller data over all requests. This patch is
doing that by introducing the calculated req_payload_size which is
updated by each frame. It the uses this amount of data to fill the
isoc requests instead of the video->req_size.

For uncompressed formats it will not make a difference since the payload
size will be equal to the imagesize. Therefore the code will have no
effecta as req_payload_size will be equal to req_size.

 STREAMING_MIN_BUFFERS in uvc_queue_setup

We set the minimum amount of v4l2 buffers that is possibly be pending
to UVCG_STREAMING_MIN_BUFFERS which is two. This way the driver will
always have at least one frame pending to be encoded while the other
is being enqueued in the hardware.

Subject: [PATCH 0817/2948] usb: gadget: uvc: dont call
 usb_composite_setup_continue when not streaming

If the streamoff call was triggered by some previous disconnect
or userspace application shutdown the uvc_function_setup_continue
should not be called and the state should not be overwritten.

For this situation the set_alt(0) was never called and the streaming ep
has no USB_GADGET_DELAYED_STATUS pending.

Since the state then was already updated before we also omit the state
update.

Subject: [PATCH 0818/2948] xhci: add helper to stop endpoint and wait for
 completion

Expose xhci_stop_endpoint_sync() which is a synchronous variant of
xhci_queue_stop_endpoint().  This is useful for client drivers that are
using the secondary interrupters, and need to stop the current endpoint
session.

This does not go through the normal xhci_handle_cmd_stop_ep() command
completion handler, because it utilizes the completion path to achieve
synchronous behavior.  Users of this API are primarily intended to be
clients that maintain their own transfer rings, such as in the case of USB
audio offload.

Subject: [PATCH 0822/2948] um: Fix passing '-n' to linker for stub_exe

When building stub_exe with clang, there is an error because '-n' is not
a recognized flag by the clang driver (which is being used to invoke the
linker):

  clang: error: unknown argument: '-n'

'-n' should be passed along to the linker, as it is the short flag for
'--nmagic', so prefix it with '-Wl,'.

Subject: [PATCH 0823/2948] um: Disable auto variable initialization for
 stub_exe.c

When automatic variable initialization is enabled via
CONFIG_INIT_STACK_ALL_{PATTERN,ZERO}, clang will insert a call to
memset() to initialize an object created with __builtin_alloca(). This
ultimately breaks the build when linking stub_exe because it is a
standalone executable that does not include or link against memset().

  ld: arch/um/kernel/skas/stub_exe.o: in function `_start':
  arch/um/kernel/skas/stub_exe.c:83:(.ltext+0x15): undefined reference to `memset'

Disable automatic variable initialization for stub_exe.c by passing the
default value of 'uninitialized' to '-ftrivial-auto-var-init', which
avoids generating the call to memset(). This code is small and runs
quickly as it is just designed to set up an environment, so stack
variable initialization is unnecessary overhead for little gain.

Subject: [PATCH 0827/2948] phy: qcom: qmp: Add phy register and clk setting
 for x1e80100 PCIe3

Currently driver supports only x4 lane based functionality using tx/rx and
tx2/rx2 pair of register sets. To support 8 lane functionality with PCIe3,
PCIe3 related QMP PHY provides additional programming which are available
as txz and rxz based register set. Hence add txz and rxz based registers
usage and programming sequences.

As soon as software programs the txz and rxz based register set, hardware
shall "broadcast" the same settings to the tx/rx pair of registers for all
the 8 lanes, which saves the effort of software programming them one by
one.

There might be some tx and/or rx registers on some lanes need minor tweaks,
program them after programming the txz and rxz reigster set.

In addition, x1e80100 uses QMP PHY ver 6.30 for PCIe Gen4 x8, hence add
two new header files to reflect the new register offsets.

Subject: [PATCH 0829/2948] phy: rockchip: inno-usb2: convert clock management
 to bulk

Since some Rockchip SoCs (e.g RK3576) have more than one clock,
this converts the clock management from single to bulk method to
make the driver more flexible.

 defines with macro

There are 47 registers defined as PHY_REG_xx were xx goes from 00 to
47.  Simplify this by replacing them all with a macro which is passed
the register number to return the proper register offset.

Subject: [PATCH 0833/2948] phy: freescale: fsl-samsung-hdmi: Simplify
 REG21_PMS_S_MASK lookup

The value of 'S' is writen to two places, PHY_REG3[7:4] and
PHY_REG21[3:0].  There is a lookup table which contains
the value of PHY_REG3.  Rather than using a switch statement
based on the pixel clock to search for the value of 'S' again,
just shift the contents of PHY_REG3[7:4] >> 4 and place the value
in PHY_REG21[3:0].  Doing this can eliminate an entire function.

Subject: [PATCH 0834/2948] phy: freescale: fsl-samsung-hdmi: Support dynamic
 integer

There is currently a look-up table for a variety of resolutions.
Since the phy has the ability to dynamically calculate the values
necessary to use the intger divider which should allow more
resolutions without having to update the look-up-table.

If the lookup table cannot find an exact match, fall back to the
dynamic calculator of the integer divider.

Previously, the value of P was hard-coded to 1, this required an
update to the phy_pll_cfg table to add in the extra value into the
table, so if the value of P is calculated to be something else
by the PMS calculator, the calculated_phy_pll_cfg structure
can be used instead without having to keep track of which method
was used.

Subject: [PATCH 0835/2948] phy: freescale: fsl-samsung-hdmi: Use closest
 divider

Currently, if the clock values cannot be set to the exact rate,
the round_rate and set_rate functions use the closest value found in
the look-up-table.  In preparation of removing values from the LUT
that can be calculated evenly with the integer calculator, it's
necessary to ensure to check both the look-up-table and the integer
divider clock values to get the closest values to the requested
value.  It does this by measuring the difference between the
requested clock value and the closest value in both integer divider
calucator and the fractional clock look-up-table.

Which ever has the smallest difference between them is returned as
the closest rate.

Subject: [PATCH 0836/2948] phy: freescale: fsl-samsung-hdmi: Remove
 unnecessary LUT entries

The lookup table contains entries which use the integer divider
instead of just the fractional divider. Since the set and round
functions check both the integer divider values and the LUT values,
it's no longer necessary to keep the integer divider values in the
lookup table, as can be dynamically calcuated.

Subject: [PATCH 0845/2948] phy: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/phy/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

While touching these files, make indention of the struct initializer
consistent in several files.

-ROCKCHIP HDMI PHY WITH INNO IP BLOCK
-
-Required properties:
- - compatible : should be one of the listed compatibles:
-	* "rockchip,rk3228-hdmi-phy",
-	* "rockchip,rk3328-hdmi-phy";
- - reg : Address and length of the hdmi phy control register set
- - clocks : phandle + clock specifier for the phy clocks
- - clock-names : string, clock name, must contain "sysclk" for system
-	  control and register configuration, "refoclk" for crystal-
-	  oscillator reference PLL clock input and "refpclk" for pclk-
-	  based refeference PLL clock input.
- - #clock-cells: should be 0.
- - clock-output-names : shall be the name for the output clock.
- - interrupts : phandle + interrupt specified for the hdmiphy interrupt
- - #phy-cells : must be 0. See ./phy-bindings.txt for details.
-
-Optional properties for rk3328-hdmi-phy:
- - nvmem-cells = phandle + nvmem specifier for the cpu-version efuse
- - nvmem-cell-names : "cpu-version" to read the chip version, required
-	  for adjustment to some frequency settings
-
-Example:
-	hdmi_phy: hdmi-phy@12030000 {
-		compatible = "rockchip,rk3228-hdmi-phy";
-		reg = <0x12030000 0x10000>;
-		#phy-cells = <0>;
-		clocks = <&cru PCLK_HDMI_PHY>, <&xin24m>, <&cru DCLK_HDMIPHY>;
-		clock-names = "sysclk", "refoclk", "refpclk";
-		#clock-cells = <0>;
-		clock-output-names = "hdmi_phy";
-		status = "disabled";
-	};
-
-Then the PHY can be used in other nodes such as:
-
-	hdmi: hdmi@200a0000 {
-		compatible = "rockchip,rk3228-dw-hdmi";
-		...
-		phys = <&hdmi_phy>;
-		phy-names = "hdmi";
-		...

The NXP PTN3222 is the single-port eUSB2 to USB2 redriver that performs
translation between eUSB2 and USB2 signalling schemes. It supports all
three data rates: Low Speed, Full Speed and High Speed.

The reset state enables autonegotiation of the PHY role and of the data
rate, so no additional programming is required.

Subject: [PATCH 0856/2948] perf test: Speed up some tests using perf list

On my system, perf list is very slow to print the whole events.  I think
there's a performance issue in SDT and uprobes event listing.  I noticed
this issue while running perf test on x86 but it takes long to check
some CoreSight event which should be skipped quickly.

Anyway, some test uses perf list to check whether the required event is
available before running the test.  The perf list command can take an
argument to specify event class or (glob) pattern.  But glob pattern is
only to suppress output for unmatched ones after checking all events.

In this case, specifying event class is better to reduce the number of
events it checks and to avoid buggy subsystems entirely.

No functional changes intended.

In the kernel, the probe group string length is limited up to
MAX_EVENT_NAME_LEN (including the NULL terminator).

Check for this limitation and report an error if it is exceeded.

Subject: [PATCH 0859/2948] perf probe: Improve log for long event name failure

If a symbol name is longer than the maximum event length (64 bytes), the
perf tool reports error:

  # perf probe -x test_cpp_mangle --add "this_is_a_very_very_long_print_data_abcdefghijklmnopqrstuvwxyz(int)"
    snprintf() failed: -7; the event name nbase='this_is_a_very_very_long_print_data_abcdefghijklmnopqrstuvwxyz(int)' is too long
    Error: Failed to add events.

An information is missed in the log that the symbol name and the event
name can be set separately. Especially, this is recommended for adding
probe for a long symbol.

This commit refines the log for reminding event syntax.

After:

  # perf probe -x test_cpp_mangle --add "this_is_a_very_very_long_print_data_abcdefghijklmnopqrstuvwxyz(int)"
    snprintf() failed: -7; the event name 'this_is_a_very_very_long_print_data_abcdefghijklmnopqrstuvwxyz(int)' is too long
      Hint: Set a shorter event with syntax "EVENT=PROBEDEF"
            EVENT: Event name (max length: 64 bytes).
      Error: Failed to add events.

Subject: [PATCH 0860/2948] perf dso: Fix symtab_type for kmod compression

During the rework of the dso structure in patch ee756ef7491eafd an
increment was forgotten for the symtab_type in case the data for
the kernel module are compressed. This affects the probing of the
kernel modules, which fails if the data are not already cached.

Increment the value of the symtab_type to its compressed variant so the
data could be recovered successfully.

Subject: [PATCH 0863/2948] tools/perf/pmu-events/powerpc: Add support for
 compat events in json

perf list picks the events supported for specific platform
from pmu-events/arch/powerpc/<platform>. Example power10 events
are in pmu-events/arch/powerpc/power10, power9 events are part
of pmu-events/arch/powerpc/power9. The decision of which
platform to pick is determined based on PVR value in powerpc.
The PVR value is matched from pmu-events/arch/powerpc/mapfile.csv

Example:

Format:
        PVR,Version,JSON/file/pathname,Type

0x004[bcd][[:xdigit:]]{4},1,power8,core
0x0066[[:xdigit:]]{4},1,power8,core
0x004e[[:xdigit:]]{4},1,power9,core
0x0080[[:xdigit:]]{4},1,power10,core
0x0082[[:xdigit:]]{4},1,power10,core

The code gets the PVR from system using get_cpuid_str function
in arch/powerpc/util/headers.c ( from SPRN_PVR ) and compares
with value from mapfile.csv

In case of compat mode, say when partition is booted in a power9
mode when the system is a power10, add an entry to pick the
ISA architected events from "pmu-events/arch/powerpc/compat".
Add json file generic-events.json which will contain these
events which is supported in compat mode.

PVR will point to power10 where as it should pick events from power9

pmu-events/arch/powerpc/compat to contain the ISA architected events
which is supported in compat mode. Also return 0x00ffffff as pvr
when booted in compat mode. Based on this pvr value, json will
pick events from pmu-events/arch/powerpc/compat

Subject: [PATCH 0866/2948] cpuidle: riscv-sbi: Add cpuidle_disabled() check

The consumer devices that inside the cpu/cluster power domain may register
the genpd notifier where their power domains point to the pd nodes under
'/cpus/power-domains'. If the cpuidle.off==1, the genpd notifier will fail
due to sbi_cpuidle_pd_allow_domain_state is not set. We also need the
sbi_cpuidle_cpuhp_up/down to invoke the callbacks. Therefore adding a
cpuidle_disabled() check before cpuidle_register() to address the issue.

Add missing dwarf_cfi_end to free memory associated with probe_finder
cfi_eh which is allocated and owned via a call to
dwarf_getcfi_elf. Confusingly cfi_dbg shouldn't be freed as its memory
is owned by the passed in debuginfo struct. Add comments to highlight
this.

This addresses leak sanitizer issues seen in:

Subject: [PATCH 0871/2948] perf stat: Display "none" for NaN with metric only
 json

Return earlier for an empty unit case. If snprintf of the fmt doesn't
produce digits between vals and ends, as happens with NaN, make the
value "none" as happens in print_metric_end.

Subject: [PATCH 0873/2948] perf stat: Change color to threshold in
 print_metric

Colors don't mean things in CSV and JSON output, switch to a threshold
enum value that the standard output can convert to a color. Updating
the CSV and JSON output will be later changes.

Subject: [PATCH 0876/2948] perf probe: Correct demangled symbols in C++
 program

An issue can be observed when probe C++ demangled symbol with steps:

  # nm test_cpp_mangle | grep print_data
    0000000000000c94 t _GLOBAL__sub_I__Z10print_datai
    0000000000000afc T _Z10print_datai
    0000000000000b38 T _Z10print_dataR5Point

  # perf probe -x /home/niayan01/test_cpp_mangle -F --demangle
    ...
    print_data(Point&)
    print_data(int)
    ...

  # perf --debug verbose=3 probe -x test_cpp_mangle --add "test=print_data(int)"
    probe-definition(0): test=print_data(int)
    symbol:print_data(int) file:(null) line:0 offset:0 return:0 lazy:(null)
    0 arguments
    Open Debuginfo file: /home/niayan01/test_cpp_mangle
    Try to find probe point from debuginfo.
    Symbol print_data(int) address found : afc
    Matched function: print_data [2ccf]
    Probe point found: print_data+0
    Found 1 probe_trace_events.
    Opening /sys/kernel/tracing//uprobe_events write=1
    Opening /sys/kernel/tracing//README write=0
    Writing event: p:probe_test_cpp_mangle/test /home/niayan01/test_cpp_mangle:0xb38
    ...

When tried to probe symbol "print_data(int)", the log shows:

    Symbol print_data(int) address found : afc

The found address is 0xafc - which is right with verifying the output
result from nm. Afterwards when write event, the command uses offset
0xb38 in the last log, which is a wrong address.

The dwarf_diename() gets a common function name, in above case, it
returns string "print_data". As a result, the tool parses the offset
based on the common name. This leads to probe at the wrong symbol
"print_data(Point&)".

To fix the issue, use the die_get_linkage_name() function to retrieve
the distinct linkage name - this is the mangled name for the C++ case.
Based on this unique name, the tool can get a correct offset for
probing. Based on DWARF doc, it is possible the linkage name is missed
in the DIE, it rolls back to use dwarf_diename().

After:

  # perf --debug verbose=3 probe -x test_cpp_mangle --add "test=print_data(int)"
    probe-definition(0): test=print_data(int)
    symbol:print_data(int) file:(null) line:0 offset:0 return:0 lazy:(null)
    0 arguments
    Open Debuginfo file: /home/niayan01/test_cpp_mangle
    Try to find probe point from debuginfo.
    Symbol print_data(int) address found : afc
    Matched function: print_data [2d06]
    Probe point found: print_data+0
    Found 1 probe_trace_events.
    Opening /sys/kernel/tracing//uprobe_events write=1
    Opening /sys/kernel/tracing//README write=0
    Writing event: p:probe_test_cpp_mangle/test /home/niayan01/test_cpp_mangle:0xafc
    Added new event:
      probe_test_cpp_mangle:test (on print_data(int) in /home/niayan01/test_cpp_mangle)

Subject: [PATCH 0877/2948] perf test: Add a shell wrapper for "Setup struct
 perf_event_attr"

The "Setup struct perf_event_attr" test in attr.c does a bunch of
directory finding to set up running a python test that in general is
more brittle than similar logic we have in shell tests. Add a shell
test that invokes and runs the tests in the python attr.py script.

Subject: [PATCH 0878/2948] perf test: Remove C test wrapper for attr.py

Remove the C wrapper now a shell script wrapper exists. Move
perf_event_attr dumping functions to evsel.c and reduce the scope of
variables/defines. Use fprintf to avoid snprintf complexities in
WRITE_ASS.

Add __SANE_USERSPACE_TYPES__ to evsel.c to fix format flag issues on
PowerPC triggered by moving attr.c functions to evsel.c.

Subject: [PATCH 0879/2948] perf test: Move attr files into shell directory
 where they are used

Now the attr tests are shell tests move the associated python and
configuration files. Update the installation build rules for the new
directories. Recycle the lib install rules for python files allowing
the explicit attr.py install line to be dropped.

Subject: [PATCH 0881/2948] um: Fix misaligned stack in stub_exe

The stub_exe could segfault when built with some compilers (e.g. gcc
13.2.0), as SSE instructions which relied on stack alignment could be
generated, but the stack was misaligned.

This seems to be due to the __start entry point being run with a 16-byte
aligned stack, but the x86_64 SYSV ABI wanting the stack to be so
aligned _before_ a function call (so it is misaligned when the function
is entered due to the return address being pushed). The function
prologue then realigns it. Because the entry point is never _called_,
and hence there is no return address, the prologue is therefore actually
misaligning it, and causing the generated movaps instructions to
SIGSEGV. This results in the following error:
start_userspace : expected SIGSTOP, got status = 139

Don't generate this prologue for __start by using
__attribute__((naked)), which resolves the issue.

Fixes: 32e8eaf263d9 ("um: use execveat to create userspace MMs")

Subject: [PATCH 0894/2948] perf probe: Move elfutils support check to libdw
 check

The test _ELFUTILS_PREREQ(0, 142) is false for elfutils before
2009-06-13, but that is 15 years ago and very unlikely. Add a test to
test-libdw.c and assume the libdw version is at least 0.142 to
simplify the build logic.

Subject: [PATCH 0895/2948] perf libdw: Remove unnecessary defines

As HAVE_DWARF_GETLOCATIONS_SUPPORT and HAVE_DWARF_CFI_SUPPORT always
match HAVE_DWARF_SUPPORT remove the macros and use
HAVE_DWARF_SUPPORT. If building the file is guarded by CONFIG_DWARF
then remove all ifs.

From 8838abf6261444f7d8047c363f90cafbd2ff32c5 Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>
Date: Wed, 16 Oct 2024 17:13:53 -0700
Subject: [PATCH 0896/2948] perf build: Rename HAVE_DWARF_SUPPORT to
 HAVE_LIBDW_SUPPORT

In Makefile.config for unwinding the name dwarf implies either
libunwind or libdw. Make it clearer that HAVE_DWARF_SUPPORT is really
just defined when libdw is present by renaming to HAVE_LIBDW_SUPPORT.

Subject: [PATCH 0897/2948] perf build: Rename CONFIG_DWARF to CONFIG_LIBDW

In Makefile.config for unwinding the name dwarf implies either
libunwind or libdw. Make it clearer that CONFIG_DWARF is really just
defined when libdw is present by renaming to CONFIG_LIBDW.

Subject: [PATCH 0898/2948] PCI: Remove unused PCI_SUBTRACTIVE_DECODE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

2fe2abf896c1 ("PCI: augment bus resource table with a list") added
PCI_SUBTRACTIVE_DECODE which is put into the struct pci_bus_resource flags
field but is never read. There seems to never have been users for it.

Remove both PCI_SUBTRACTIVE_DECODE and the flags field from the struct
pci_bus_resource.

Subject: [PATCH 0901/2948] RISC-V: Check scalar unaligned access on all CPUs

Originally, the check_unaligned_access_emulated_all_cpus function
only checked the boot hart. This fixes the function to check all
harts.

Subject: [PATCH 0902/2948] RISC-V: Scalar unaligned access emulated on hotplug
 CPUs

The check_unaligned_access_emulated() function should have been called
during CPU hotplug to ensure that if all CPUs had emulated unaligned
accesses, the new CPU also does.

This patch adds the call to check_unaligned_access_emulated() in
the hotplug path.

Subject: [PATCH 0904/2948] RISC-V: Detect unaligned vector accesses supported

Run an unaligned vector access to test if the system supports
vector unaligned access. Add the result to a new key in hwprobe.
This is useful for usermode to know if vector misaligned accesses are
supported and if they are faster or slower than equivalent byte accesses.

Subject: [PATCH 0905/2948] RISC-V: Report vector unaligned access speed
 hwprobe

Detect if vector misaligned accesses are faster or slower than
equivalent vector byte accesses. This is useful for usermode to know
whether vector byte accesses or vector misaligned accesses have a better
bandwidth for operations like memcpy.

Subject: [PATCH 0911/2948] staging: gpib: avoid unused const variables

Variables that are 'static const' but not used anywhere cause a warning
with "gcc -Wunused-const-variable", which we may want to enable by default
in the future.

The gpib code already has a mix of 'enum' and 'static const' variables
for named constants, so convert the ones that are causing problems to
enums as well, or move them closer to the only users where possible.

Subject: [PATCH 0912/2948] staging: gpib: pc2: avoid calling undefined
 dma_free()

On architectures that don't support the ISA DMA API, this causes a build
failure. The corresponding dma_alloc() call is already in an #ifdef,
so use the same one for dma_free().

Note that nothing seems to set PC2_DMA, so parts of this driver
are likely unused. ISA DMA usually does not work on PCI or PCMCIA
devices, only on physical ISA slots.

Subject: [PATCH 0913/2948] staging: gpib: make port I/O code conditional

A few of the helper modules contain functions for both IORESOURCE_MEM
and IORESOURCE_IO type access, with the latter not being supported
on all architectures but also not used by all the drivers.

Add #ifdef checks around these to allow building the library code
and use it on MMIO-only configurations.

Subject: [PATCH 0914/2948] staging: gpib: add bus specific Kconfig
 dependencies

A number of GPIB drivers fail to build when CONFIG_HAS_IOPORT is disabled,
which can be avoided with a CONFIG_ISA_BUS or CONFIG_PCMCIA dependency.

For completeness, mark all of the new device drivers with a dependency
on whichever bus they use, and hide the symbols for chip drivers that
are already selected by teh device drivers using them.

Using a string variable as a format causes a -Wformat-security
warning. Since the only use of the temporary module_string[] is to hold
the sprintf() output, just pass the format string and argument directly
to request_module().

Subject: [PATCH 0923/2948] staging: vchiq_core: Simplify bulk data preparatory
 functions

Two functions create_pagelist() and vchiq_prepare_bulk_data()
open code bulk data arguments ('size' and 'dir') in their function
signatures which can easily be obtained by struct vchiq_bulk pointer.

Retrieve the arguments from vchiq_bulk pointer instead and reduce
the number of arguments passed in create_pagelist() and
vchiq_bulk_prepare_data().

No functional changes intended in this patch.

Subject: [PATCH 0924/2948] staging: vc04_services: Simplify block bulk
 transfer code paths

Blocking bulk transfer functions tend to open-code every function
parameter needed to initiate the bulk transfer. Instead of doing
that, simply pass a populated struct vchiq_bulk down the function
chain.

Subject: [PATCH 0926/2948] staging: vchiq_core: Simplify bulk transfer queue
 message function

vchiq_bulk_xfer_queue_msg_killable() is a common function between
various bulk transfer code paths (blocking, callback and no-callback).
These code paths were simplified earlier by passing a populated
struct vchiq_bulk pointer in order to avoid open-coding the parameters
required to initiate a bulk transfer.

Now simplify the vchiq_bulk_xfer_queue_msg_killable() in a similar way
i.e. avoid open-coding the function parameters and pass the struct
vchiq_bulk pointer directly, coming from the various bulk transfer code
paths.

Subject: [PATCH 0927/2948] staging: vchiq_dev: Drop userdata local pointer

The 'userdata' local pointer can be dropped which is set to bulk_waiter.
We can directly pass the waiter->bulk_waiter pointer to
vchiq_bulk_xfer_waiting().

Subject: [PATCH 0928/2948] perf test: Update all metrics test like
 metricgroups test

Like in the metricgroup tests, it should check the permission first and
then skip relevant failures accordingly.

Also it needs to try again with the system wide flag properly.  On the
second round, check if the result has the metric name because other
failure cases are checked in the first round already.

Subject: [PATCH 0929/2948] perf test: Fix perf test case 84 on s390

Perf test case 84 'perf pipe recording and injection test'
sometime fails on s390, especially on z/VM virtual machines.

This is caused by a very short run time of workload

  # perf test -w noploop

which runs for 1 second. Occasionally this is not long
enough and the perf report has no samples for symbol noploop.

Fix this and enlarge the runtime for the perf work load
to 3 seconds. This ensures the symbol noploop is always
present. Since only s390 is affected, make this loop
architecture dependend.

Output before:
 Inject -b build-ids test
 [ perf record: Woken up 1 times to write data ]
 [ perf record: Captured and wrote 0.195 MB - ]
 [ perf record: Woken up 1 times to write data ]
 [ perf record: Captured and wrote 0.277 MB - ]

 Inject -b build-ids test [Success]

 [ perf record: Woken up 1 times to write data ]
 [ perf record: Captured and wrote 0.014 MB - ]
 Inject --buildid-all build-ids test [Failed - cannot find
				noploop function in pipe #2]

Output after:
Successful execution for over 10 times in a loop.

Subject: [PATCH 0931/2948] perf vendor events amd: Add Zen 5 data fabric
 metrics

Add data fabric metrics taken from Section 2.1.16.2 "Performance
Measurement" in the Processor Programming Reference (PPR) for AMD Family
1Ah Model 02h Revision C1 Processors document available at the link
below.

The recommended metrics are sourced from Table 28 "Guidance for Common
Performance Statistics with Complex Event Selects". They capture data
bandwidth for various links and interfaces in the data fabric.

Subject: [PATCH 0932/2948] perf vendor events amd: Update Zen 5 data cache
 fill events

For events that count data cache fills, some combinations of the unit
mask bits are useful for counting fills from local caches, DRAM or any
far sources. However, named events currently exist for PMCx044 (Any Data
Cache Fills) only. Add similar events for the following base events.
  * PMCx043 (Demand Data Cache Fills)
  * PMCx059 (Software Prefetch Data Cache Fills)
  * PMCx05A (Hardware Prefetch Data Cache Fills)

While at it, remove "ls_any_fills_from_sys.all_dram_io" since it is a
duplicate of "ls_any_fills_from_sys.dram_io_all".

Event descriptions can be found in Section 2.1.16.5.2 "Load/Store (LS)
Events" of the Processor Programming Reference (PPR) for AMD Family 1Ah
Model 02h Revision C1 Processors document available at the link below.

Subject: [PATCH 0934/2948] pinctrl: spacemit: add support for SpacemiT K1 SoC

SpacemiT's K1 SoC has a pinctrl controller which use single register
to describe all functions, which include bias pull up/down(strong pull),
drive strength, schmitter trigger, slew rate, mux mode.

Subject: [PATCH 0935/2948] modules: Ensure 64-bit alignment on __ksymtab_*
 sections

On 64-bit architectures without CONFIG_HAVE_ARCH_PREL32_RELOCATIONS
(e.g. ppc64, ppc64le, parisc, s390x,...) the __KSYM_REF() macro stores
64-bit pointers into the __ksymtab* sections.
Make sure that those sections will be correctly aligned at module link time,
otherwise unaligned memory accesses may happen at runtime.

As per unaligned-memory-access [0] "unaligned memory accesses [...]
will not work correctly on certain platforms and will cause performance
problems on others", so fix this.

The __kcrctab* sections store 32-bit entities, so use ALIGN(4) for those.

The entry for __ex_table was missing, which may make __ex_table
become 1- or 2-byte aligned in modules.
Add the entry to ensure it gets 32-bit aligned.

Subject: [PATCH 0940/2948] module: Factor out elf_validity_cache_secstrings

Factor out the validation of section names.

There are two behavioral changes:

1. Previously, we did not validate non-SHF_ALLOC sections.
   This may have once been safe, as find_sec skips non-SHF_ALLOC
   sections, but find_any_sec, which will be used to load BTF if that is
   enabled, ignores the SHF_ALLOC flag. Since there's no need to support
   invalid section names, validate all of them, not just SHF_ALLOC
   sections.
2. Section names were validated *after* accessing them for the purposes
   of detecting ".modinfo" and ".gnu.linkonce.this_module". They are now
   checked prior to the access, which could avoid bad accesses with
   malformed modules.

Subject: [PATCH 0944/2948] module: Factor out elf_validity_cache_index_str

Pull out index validation for the symbol string section.

Note that this does not validate the *contents* of the string table,
only shape and presence of the section.

Validate properties of the strtab that are depended on elsewhere, but
were previously unchecked:
* String table nonempty (offset 0 is valid)
* String table has a leading NUL (offset 0 corresponds to "")
* String table is NUL terminated (strfoo functions won't run out of the
  table while reading).
* All symbols names are inbounds of the string table.

Subject: [PATCH 0959/2948] drm/panic: avoid reimplementing Iterator::find
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rust's standard library's `std::iter::Iterator` trait provides a function
`find` that finds the first element that satisfies a predicate.
The function `Version::from_segments` is doing the same thing but is
implementing the same logic itself.

Clippy complains about this in the `manual_find` lint:

    error: manual implementation of `Iterator::find`
       --> drivers/gpu/drm/drm_panic_qr.rs:212:9

    214 | |                 return Some(v);
    215 | |             }

        = help: to override `-D warnings` add `#[allow(clippy::manual_find)]`

Use `Iterator::find` instead to make the intention clearer.

At the same time, clean up the redundant closure that Clippy warns
about too:

Subject: [PATCH 0960/2948] drm/panic: remove unnecessary borrow in
 alignment_pattern
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The function `alignment_pattern` returns a static reference to a `u8`
slice. The borrow of the returned element in `ALIGNMENT_PATTERNS` is
already a reference as defined in the array definition above so this

While this can be useful in a lot of cases, it isn't here because the

means losing clarity, so opt-out of this lint for the offending line.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/power/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

While touching these files, make indention of the struct initializer
consistent in several files.

 driver

Since the DSA/IAA device IDs are only used by the IDXD driver, there is
no need to define them as public IDs. Move their definitions to the IDXD
driver to limit their scope. This change helps reduce unnecessary
exposure of the device IDs in the global space, making the codebase
cleaner and better encapsulated.

There is no functional change.

Subject: [PATCH 0973/2948] dt-bindings: dma: stm32-dma3: prevent
 packing/unpacking mode

When source data width/burst and destination data width/burst are
different, data are packed or unpacked in DMA3 channel FIFO.
Data are pushed out from DMA3 channel FIFO when the destination burst
length (= data width * burst) is reached.
If the channel is stopped before the transfer end, and if some bytes are
packed/unpacked in the DMA3 channel FIFO, these bytes are lost.
Indeed, DMA3 channel FIFO has no flush capability, only reset.
To avoid potential bytes lost, pack/unpack must be prevented by setting
memory data width/burst equal to peripheral data width/burst.
Memory accesses will be penalized. But it is the only way to avoid bytes
lost.

Some devices (e.g. cyclic RX like UART) need this, so add the possibility
to prevent pack/unpack feature, by setting bit 16 of the 'DMA transfer
requirements' bit mask.

Subject: [PATCH 0974/2948] dmaengine: stm32-dma3: prevent pack/unpack thanks
 to DT configuration

When source data width/burst and destination data width/burst are
different, data are packed or unpacked in DMA3 channel FIFO, using
CxTR1.PAM.
Data are pushed out from DMA3 channel FIFO when the destination burst
length (= data width * burst) is reached.
If the transfer is stopped before CxBR1.BNDT = 0, and if some bytes are
packed/unpacked in the DMA3 channel FIFO, these bytes are lost.
Indeed, DMA3 channel FIFO has no flush capability, only reset.
To avoid potential bytes lost, pack/unpack must be prevented by setting
memory data width/burst equal to peripheral data width/burst.
Memory accesses will be penalized. But it is the only way to avoid bytes
lost.

Prevent pack/unpack feature can be activated by setting bit 16 of DMA3
Transfer requirements bitfield (tr_conf) in device tree.

Subject: [PATCH 0975/2948] dmaengine: stm32-dma3: refactor HW linked-list to
 optimize memory accesses

Current behavior splits the buffer/sg in n * STM32_DMA3_MAX_BLOCK_SIZE + 1
for the remainder without optimization.

New behavior splits the buffer/sg in n * STM32_DMA3_MAX_BLOCK_SIZE + 1 for
(x * chan->max_burst) + 1 for the remainder.
Depending on channel FIFO size, optimal double-word (word if only 8-byte
FIFO size) bursts can be programmed before managing the very last remainder
with lower data width.
In case of _prep_slave_sg, and depending on the channel Transfer Complete
event configuration, the user is warned about the refactored linked-list,
not having the same items count than the initial sg_list. This warning is
shown only if the configuration is successful.

Subject: [PATCH 0976/2948] dt-bindings: dma: stm32-dma3: prevent additional
 transfers

Some devices require a single transfer. For example, reading FMC ECC status
registers does not support multiple transfers.
Add the possibility to prevent additional transfers, by setting bit 17 of
the 'DMA transfer requirements' bit mask.

Subject: [PATCH 0977/2948] dmaengine: stm32-dma3: prevent LL refactoring
 thanks to DT configuration

stm32-dma3 driver refactors the linked-list in order to address the memory
with the highest possible data width.
It means that it can introduce up to 2 linked-list items. One with a
transfer length multiple of channel maximum burst length and so with the
highest possible data width. And an extra one with the latest bytes, with
lower data width.
Some devices (e.g. FMC ECC) don't support having several transfers instead
of only one.
So add the possibility to prevent linked-list refactoring, when bit 17 of
the 'DMA transfer requirements' bit mask is set in device tree.
When NOPACK feature is used (bit 16 pf the 'DMA transfer requirements' bit
mask in device tree), linked-list refactoring can be avoided, since the
memory data width and burst will be aligned with the device ones.

Subject: [PATCH 0978/2948] dmaengine: stm32-dma3: clamp AXI burst using match
 data

STM32 DMA3 can be interconnected with AXI3 or AXI4 busses. In case it is
interconnected with AXI3, the maximum burst length supported by AXI3
protocol is 16 beats, which is lower than the maximum burst length
supported by STM32 DMA3. So the programmed burst has to be shortened when
AXI port is used.
Introduce struct stm32_dma3_pdata to specify the specific configurations
(e.g. AXI maximum burst length) required by the SoC, so implied by the SoC
specific compatible.

Subject: [PATCH 0985/2948] iio: gyro: bmg160: Drop most likely fake ACPI IDs

The commits in question do not proove that ACPI IDs exist.
Quite likely it was a cargo cult addition while doing that
for DT-based enumeration. Drop most likely fake ACPI IDs.

The to be removed IDs has been checked against the following resources:
1) DuckDuckGo
2) Google
3) MS catalog: https://www.catalog.update.microsoft.com/Search.aspx
This gives no useful results in regard to DSDT, moreover, the official
vendor IDs in the registry for Bosh are BSG and BOSC.

Subject: [PATCH 0991/2948] iio: pressure: bmp280: Use sleep and forced mode
 for oneshot captures

Add forced mode support in sensors BMP28x, BME28x, BMP3xx and BMP58x.
Sensors BMP18x and BMP085 are old and do not support this feature so
their operation is not affected at all.

Essentially, up to now, the rest of the sensors were used in normal mode
all the time. This means that they are continuously doing measurements
even though these measurements are not used. Even though the sensor does
provide PM support, to cover all the possible use cases, the sensor needs
to go into sleep mode and wake up whenever necessary.

The idea is that the sensor is by default in sleep mode, wakes up in
forced mode when a oneshot capture is requested, or in normal mode
when the buffer is enabled. The difference lays in the fact that in
forced mode, the sensor does only one conversion and goes back to sleep
while in normal mode, the sensor does continuous measurements with the
frequency that was set in the ODR registers.

The bmpX_chip_config() functions which are responsible for applying
the requested configuration to the sensor, are modified accordingly
in order to set the sensor by default in sleep mode.

DEEP STANDBY, Low Power NORMAL and CONTINUOUS modes, supported only by
the BMP58x version, are not added.

Subject: [PATCH 0993/2948] iio: pressure: bmp280: Add data ready trigger
 support

The BMP3xx and BMP5xx sensors have an interrupt pin which can be used as
a trigger for when there are data ready in the sensor for pick up.

This use case is used along with NORMAL_MODE in the sensor, which allows
the sensor to do consecutive measurements depending on the ODR rate value.

The trigger pin can be configured to be open-drain or push-pull and either
rising or falling edge.

No support is added yet for interrupts for FIFO, WATERMARK and out of range
values.

Subject: [PATCH 0994/2948] iio: pressure: bmp280: Move bmp085 interrupt to new
 configuration

This commit intends to add the old BMP085 sensor to the new IRQ interface
of the driver for consistence. No functional changes intended.

The BMP085 sensor is equivalent with the BMP180 with the only difference of
BMP085 having an extra interrupt pin to inform about an End of Conversion.

Subject: [PATCH 0998/2948] iio: addac: ad74413r: drop reset_gpio from struct
 ad74413r_state

We just need the reset gpio during probe so there's no need to keep it
in our state struct. Hence, move devm_gpiod_get_optional() into
ad74413r_reset() and use a local struct gpio_desc.

While at it, request the gpio in the asserted state (GPIOD_OUT_HIGH) so
that we already perform the reset while requesting the gpio saving us a
call to gpiod_set_value_cansleep().

Also, explicitly include <gpio/consumer.h> for
devm_gpiod_get_optional().

It's highly unlikely for the converter ref voltage to change at runtime.
Hence, let's read the voltage and save it (instead of the regulator
struct). While at it, simplify the code by using
devm_regulator_get_enable_read_voltage().

Subject: [PATCH 1000/2948] iio: addac: ad74413r: simplify with cleanup.h

Make use of mutex guard() and IIO iio_device_claim_direct_scoped() to
simplify code and error handling.

While at it, use devm_mutex_init() to initialize the mutex.

Subject: [PATCH 1001/2948] dt-bindings: iio: adc: ad7606: Remove spi-cpha from
 required

The documentation is erroneously stating that spi-cpha is required, and
the example is erroneously setting both spi-cpol and spi-cpha. According
to the datasheet, only cpol should be set.

On zedboard for instance, setting the devicetree as in the example will
simply not work.

Subject: [PATCH 1002/2948] dt-bindings: iio: adc: ad7606: Add iio backend
 bindings

Add the required properties for iio-backend support, as well as an
example and the conditions to mutually exclude interruption and
conversion trigger with iio-backend.
The iio-backend's function is to controls the communication, and thus the
interruption pin won't be available anymore.
As a consequence, the conversion pin must be controlled externally since
we will miss information about when every single conversion cycle (i.e
conversion + data transfer) ends, hence a PWM is introduced to trigger
the conversions.

+AD7606 driver
+=============
+
+ADC driver for Analog Devices Inc. AD7606 and similar devices. The module name
+is ``ad7606``.
+
+Supported devices
+=================
+
+The following chips are supported by this driver:
+
+* `AD7605 <https://www.analog.com/en/products/ad7605.html>`_
+* `AD7606 <https://www.analog.com/en/products/ad7606.html>`_
+* `AD7606B <https://www.analog.com/en/products/ad7606b.html>`_
+* `AD7616 <https://www.analog.com/en/products/ad7616.html>`_
+
+Supported features
+==================
+
+SPI wiring modes
+----------------
+
+These ADCs can output data on several SDO lines (1/2/4/8). The driver
+currently supports only 1 SDO line.
+
+Parallel wiring mode
+--------------------
+
+There is also a parallel interface, with 16 lines (that can be reduced to 8 in
+byte mode). The parallel interface is selected by declaring the device as
+platform in the device tree (with no io-backends node defined, see below).
+
+IIO-backend mode
+----------------
+
+This mode allows to reach the best sample rates, but it requires an external
+hardware (eg HDL or APU) to handle the low level communication.
+The backend mode is enabled when through the definition of the "io-backends"
+property in the device tree.
+
+The reference configuration for the current implementation of IIO-backend mode
+is the HDL reference provided by ADI:
+https://wiki.analog.com/resources/eval/user-guides/ad7606x-fmc/hdl
+
+This implementation embeds an IIO-backend compatible IP (adi-axi-adc) and a PWM
+connected to the conversion trigger pin.

+
+Software and hardware modes
+---------------------------
+
+While all the AD7606/AD7616 series parts can be configured using GPIOs, some of
+them can be configured using register.
+
+The chips that support software mode have more values available for configuring
+the device, as well as more settings, and allow to control the range and
+calibration per channel.
+
+The following settings are available per channel in software mode:
+ - Scale
+
+Also, there is a broader choice of oversampling ratios in software mode.
+
+Conversion triggering
+---------------------
+
+The conversion can be triggered by two distinct ways:
+
+ - A GPIO is connected to the conversion trigger pin, and this GPIO is controlled
+   by the driver directly.  In this configuration, the driver sets back the
+   conversion trigger pin to high as soon as it has read all the conversions.
+
+ - An external source is connected to the conversion trigger pin. In the
+   current implementation, it must be a PWM. In this configuration, the driver
+   does not control directly the conversion trigger pin. Instead, it can
+   control the PWM's frequency. This trigger is enabled only for iio-backend.
+
+Reference voltage
+-----------------
+
+2 possible reference voltage sources are supported:
+
+ - Internal reference (2.5V)
+ - External reference (2.5V)
+
+The source is determined by the device tree. If ``refin-supply`` is present,
+then the external reference is used, otherwise the internal reference is used.
+
+Oversampling
+------------
+
+This family supports oversampling to improve SNR.
+In software mode, the following ratios are available:
+1 (oversampling disabled)/2/4/8/16/32/64/128/256.
+
+Unimplemented features
+----------------------
+
+- 2/4/8 SDO lines
+- CRC indication
+- Calibration
+
+Device buffers
+==============
+
+IIO triggered buffer
+--------------------
+
+This driver supports IIO triggered buffers, with a "built in" trigger, i.e the
+trigger is allocated and linked by the driver, and a new conversion is triggered
+as soon as the samples are transferred, and a timestamp channel is added to make
+up for the potential jitter induced by the delays in the interrupt handling.
+
+IIO backend buffer
+------------------
+
+When IIO backend is used, the trigger is not needed, and the sample rate is
+considered as stable. There is no timestamp channel. The communication is
+delegated to an external logic, called a backend, and the backend's driver
+handles the buffer. When this mode is enabled, the driver cannot control the
+conversion pin, because the busy pin is bound to the backend.

Subject: [PATCH 1004/2948] iio: adc: ad7606: Add PWM support for conversion
 trigger

Until now, the conversion were triggered by setting high the GPIO
connected to the convst pin. This commit gives the possibility to
connect the convst pin to a PWM.
Connecting a PWM allows to have a better control on the samplerate,
but it must be handled with care, as it is completely decorrelated of
the driver's busy pin handling.
Hence it is not recommended to be used "as is" but must be exploited
in conjunction with IIO backend, and for now only a mock functionality
is enabled, i.e PWM never swings, but is used as a GPIO, i.e duty_cycle
== period equals high state, duty_cycle == 0 equals low state.

This mock functionality will be disabled after the IIO backend usecase
is introduced.

Subject: [PATCH 1005/2948] iio: adc: ad7606: Add compatibility to fw_nodes

On the parallel version, the current implementation is only compatible
with id tables and won't work with fw_nodes, this commit intends to fix
it.

Doing so required to declare ad7606_chip_info structures in the .h file
so to make them accessible to all the driver files that can set a
pointer to the corresponding chip as the driver data.

Subject: [PATCH 1006/2948] iio: adc: ad7606: Introduce num_adc_channels

This variable determines how many hardware channels has the chip,
oppositely to the num_channels that can contain more channels, e.g a
timestamp channel in our case. Introducing this variable avoids
decreasing the former num_channels variable when reading the ADC's
channels, and clarifies a bit the code.

Subject: [PATCH 1007/2948] iio: adc: ad7606: Add iio-backend support

- Basic support for iio backend.
- Supports IIO_CHAN_INFO_SAMP_FREQ R/W.
- Only hardware mode is available, and that IIO_CHAN_INFO_RAW is not
  supported if iio-backend mode is selected.

Subject: [PATCH 1008/2948] iio: adc: ad7606: Disable PWM usage for non backend
 version

Since the pwm was introduced before backend, there was a mock use, with
a GPIO emulation. Now that iio backend is introduced, the mock use can
be removed.

+description: |
+  The AD777X family consist of 8-channel, simultaneous sampling analog-to-
+  digital converter (ADC). Eight full Σ-Δ ADCs are on-chip. The
+  AD7771 provides an ultralow input current to allow direct sensor
+  connection. Each input channel has a programmable gain stage
+  allowing gains of 1, 2, 4, and 8 to map lower amplitude sensor
+  outputs into the full-scale ADC input range, maximizing the
+  dynamic range of the signal chain.

Subject: [PATCH 1010/2948] dt-bindings: phy: bcm-ns-usb2-phy: drop deprecated
 variant
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The old binding variant (the one covering whole DMU block) was
deprecated 3 years ago. Linux kernel was warning when using it for
similar amount of time.

There aren't any known Northstar devices with bootloader providing DT to
operating system. Actually OpenWrt seems to be the only project using
this binding and it always appends DTB to kernel. It has switched to the
non-deprecated binding years ago.

Given there is close to zero chance this breaks anyone's setup it should
more than safe to drop this binding variant after 3 years.

Subject: [PATCH 1017/2948] phy: sparx5-serdes: add indirection layer to
 register macros

The register macros are used to read and write to the SERDES registers.
The registers are largely the same on Sparx5 and lan969x, however some
register target sizes differ. Therefore we introduce a new indirection
to the register macros. The target sizes are looked up, using a mapping
table (sparx5_serdes_tsize) that maps the register target to the
register target size.

With this addition, we can reuse all the existing macros for lan969x.

Also the autogenerated macros are now formatted slightly different, to
adhere to a 80 character limit.

Subject: [PATCH 1018/2948] phy: sparx5-serdes: add support for branching on
 chip type

In preparation for lan969x, add a way to branch out on code that is to
be executed on either Sparx5 or lan969x.  Initially, this is required to
branch out when checking the SERDES types and SERDES speeds, since the
handling of these differ on the two platforms. This will also be used by
the lan969x driver introduced in a subsequent patch.

 ThisModule doc comment

The doc comment for `ThisModule` incorrectly states the C header file
for `THIS_MODULE` as `include/linux/export.h`, while the correct path is
`include/linux/init.h`. This is because `THIS_MODULE` was moved in
commit 5b20755b7780 ("init: move THIS_MODULE from <linux/export.h> to
<linux/init.h>").

Update the doc comment for `ThisModule` to reflect the correct header

+
+Overview
+========
+
+TPH (TLP Processing Hints) is a PCIe feature that allows endpoint devices
+to provide optimization hints for requests that target memory space.
+These hints, in a format called Steering Tags (STs), are embedded in the
+requester's TLP headers, enabling the system hardware, such as the Root
+Complex, to better manage platform resources for these requests.
+
+For example, on platforms with TPH-based direct data cache injection
+support, an endpoint device can include appropriate STs in its DMA
+traffic to specify which cache the data should be written to. This allows
+the CPU core to have a higher probability of getting data from cache,
+potentially improving performance and reducing latency in data
+processing.
+
+
+How to Use TPH
+==============
+
+TPH is presented as an optional extended capability in PCIe. The Linux
+kernel handles TPH discovery during boot, but it is up to the device
+driver to request TPH enablement if it is to be utilized. Once enabled,
+the driver uses the provided API to obtain the Steering Tag for the
+target memory and to program the ST into the device's ST table.
+
+Enable TPH support in Linux
+---------------------------
+
+To support TPH, the kernel must be built with the CONFIG_PCIE_TPH option
+enabled.
+
+Manage TPH
+----------
+
+To enable TPH for a device, use the following function::
+
+  int pcie_enable_tph(struct pci_dev *pdev, int mode);
+
+This function enables TPH support for device with a specific ST mode.
+Current supported modes include:
+
+  * PCI_TPH_ST_NS_MODE - NO ST Mode
+  * PCI_TPH_ST_IV_MODE - Interrupt Vector Mode
+  * PCI_TPH_ST_DS_MODE - Device Specific Mode
+
+`pcie_enable_tph()` checks whether the requested mode is actually
+supported by the device before enabling. The device driver can figure out
+which TPH mode is supported and can be properly enabled based on the
+return value of `pcie_enable_tph()`.
+
+To disable TPH, use the following function::
+
+  void pcie_disable_tph(struct pci_dev *pdev);
+
+Manage ST
+---------
+
+Steering Tags are platform specific. PCIe spec does not specify where STs
+are from. Instead PCI Firmware Specification defines an ACPI _DSM method
+(see the `Revised _DSM for Cache Locality TPH Features ECN
+<https://members.pcisig.com/wg/PCI-SIG/document/15470>`_) for retrieving
+STs for a target memory of various properties. This method is what is
+supported in this implementation.
+
+To retrieve a Steering Tag for a target memory associated with a specific
+CPU, use the following function::
+
+  int pcie_tph_get_cpu_st(struct pci_dev *pdev, enum tph_mem_type type,
+                          unsigned int cpu_uid, u16 *tag);
+
+The `type` argument is used to specify the memory type, either volatile
+or persistent, of the target memory. The `cpu_uid` argument specifies the
+CPU where the memory is associated to.
+
+After the ST value is retrieved, the device driver can use the following
+function to write the ST into the device::
+
+  int pcie_tph_set_st_entry(struct pci_dev *pdev, unsigned int index,
+                            u16 tag);
+
+The `index` argument is the ST table entry index the ST tag will be
+written into. `pcie_tph_set_st_entry()` will figure out the proper
+location of ST table, either in the MSI-X table or in the TPH Extended
+Capability space, and write the Steering Tag into the ST entry pointed by
+the `index` argument.
+
+It is completely up to the driver to decide how to use these TPH
+functions. For example a network device driver can use the TPH APIs above
+to update the Steering Tag when interrupt affinity of a RX/TX queue has
+been changed. Here is a sample code for IRQ affinity notifier:
+
+.. code-block:: c
+
+    static void irq_affinity_notified(struct irq_affinity_notify *notify,
+                                      const cpumask_t *mask)
+    {
+         struct drv_irq *irq;
+         unsigned int cpu_id;
+         u16 tag;
+
+         irq = container_of(notify, struct drv_irq, affinity_notify);
+         cpumask_copy(irq->cpu_mask, mask);
+
+         /* Pick a right CPU as the target - here is just an example */
+         cpu_id = cpumask_first(irq->cpu_mask);
+
+         if (pcie_tph_get_cpu_st(irq->pdev, TPH_MEM_TYPE_VM, cpu_id,
+                                 &tag))
+             return;
+
+         if (pcie_tph_set_st_entry(irq->pdev, irq->msix_nr, tag))
+             return;
+    }
+
+Disable TPH system-wide
+-----------------------
+
+There is a kernel command line option available to control TPH feature:
+    * "notph": TPH will be disabled for all endpoint devices.

+description: |
+  RPMh interconnect providers support system bandwidth requirements through
+  RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
+  able to communicate with the BCM through the Resource State Coordinator (RSC)
+  associated with each execution environment. Provider nodes must point to at
+  least one RPMh device child node pertaining to their RSC and each provider
+  can map to multiple RPMh resources.

+description: |
+  RPMh interconnect providers support system bandwidth requirements through
+  RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
+  able to communicate with the BCM through the Resource State Coordinator (RSC)
+  associated with each execution environment. Provider nodes must point to at
+  least one RPMh device child node pertaining to their RSC and each provider
+  can map to multiple RPMh resources.

Subject: [PATCH 1039/2948] interconnect: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/interconnect to use
.remove(), with the eventual goal to drop struct
platform_driver::remove_new(). As .remove() and .remove_new() have the
same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

Subject: [PATCH 1040/2948] interconnect: qcom: add QCS8300 interconnect
 provider driver

Add driver for the Qualcomm interconnect buses found in QCS8300
based platforms. The topology consists of several NoCs that are
controlled by a remote processor that collects the aggregated
bandwidth for each master-slave pairs.

When mounting of a corrupted disk image fails, the error message printed
can reference uninitialized inode fields.  To prevent that from happening,
always initialize those fields.

rust-next contains a commit that will enable them, so we should fix
them.

Subject: [PATCH 1048/2948] PCI: cpqphp: Fix PCIBIOS_* return value confusion
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Code in and related to PCI_RefinedAccessConfig() has three types of return
type confusion:

 - PCI_RefinedAccessConfig() tests pci_bus_read_config_dword() return value
   against -1.

 - PCI_RefinedAccessConfig() returns both -1 and PCIBIOS_* return codes.

 - Callers of PCI_RefinedAccessConfig() only test for -1.

Make PCI_RefinedAccessConfig() return PCIBIOS_* codes consistently and
adapt callers accordingly.

 detect presence
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The intent of the first part in PCI_RefinedAccessConfig() is to read Vendor
ID register and detect presence of the device that way.

Remove PCI_RefinedAccessConfig() (which was not named very helpfully to
begin with) and replace the call with pci_bus_read_dev_vendor_id() + read
config because it makes the logic more obvious at the caller side.

Subject: [PATCH 1051/2948] PCI: cpqphp: Simplify PCI_ScanBusForNonBridge()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PCI_ScanBusForNonBridge() has two loops, one to search for non-bridges and
a second to look for bridges. The second loop has hints in a debug print it
should do recursion for buses underneath the bridge, but no recursion is
attempted.

Since the second loop is quite useless in its current form, just eliminate
it. This code hasn't been touched for very long time so either it's unused
or the missing parts are not important enough for anyone to attempt to add
them.

Leave only a warning print and comment about the missing recursion for the
unlikely case that somebody comes across the lack of functionality. In any
case, search whether an endpoint exists downstream of a bridge sounds
generic enough to belong to core so if the functionality is to be extended
it should probably be moved into PCI core.

Subject: [PATCH 1052/2948] perf tools: Add fallback for exclude_guest

Commit 7b100989b4f6bce70 ("perf evlist: Remove __evlist__add_default")
changed to parse "cycles:P" event instead of creating a new cycles
event for perf record.  But it also changed the way how modifiers are
handled so it doesn't set the exclude_guest bit by default.

It seems Apple M1 PMU requires exclude_guest set and returns EOPNOTSUPP
if not.  Let's add a fallback so that it can work with default events.

Also update perf stat hybrid tests to handle possible u or H modifiers.

Subject: [PATCH 1053/2948] perf tools: Don't set attr.exclude_guest by default

The exclude_guest in the event attribute is to limit profiling in the
host environment.  But I'm not sure why we want to set it by default
cause we don't care about it in most cases and I feel like it just
makes new PMU implementation complicated.

Of course it's useful for perf kvm command so I added the
exclude_GH_default variable to preserve the old behavior for perf kvm
and other commands like perf record and stat won't set the exclude bit.
This is helpful for AMD IBS case since having exclude_guest bit will
clear new feature bit due to the missing feature check logic.

  $ sysctl kernel.perf_event_paranoid
  kernel.perf_event_paranoid = 0

  $ perf record -W -e ibs_op// -vv true 2>&1 | grep switching
  switching off PERF_FORMAT_LOST support
  switching off weight struct support
  switching off bpf_event
  switching off ksymbol
  switching off cloexec flag
  switching off mmap2
  switching off exclude_guest, exclude_host

Intestingly, I found it sets the exclude_bit if "u" modifier is used.
I don't know why but it's neither intuitive nor consistent.  Let's
remove the bit there too.

Since it doesn't set the exclude_guest, no need to special handle the
bit and simply show only if one of host or guest bit is set.  Now the
default event name might not have :H prefix anymore so change the
dlfilter test not to compare the ":" at the end.

Subject: [PATCH 1055/2948] perf tools: Do not set exclude_guest for precise_ip

It seems perf sets the exclude_guest bit because of Intel PEBS
implementation which uses a virtual address.  IIUC now kernel disables
PEBS when it goes to the guest mode regardless of this bit so we don't
need to set it explicitly.  At least for the other archs/vendors.

I found the commit 1342798cc13e set the exclude_guest for precise_ip
in the tool and the commit 20b279ddb38c added kernel side enforcement
which was reverted by commit a706d965dcfd later.

Actually it doesn't set the exclude_guest for the default event
(cycles:P) already.

  $ grep -m1 vendor /proc/cpuinfo
  vendor_id	: GenuineIntel

  $ perf record -e cycles:P true
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.002 MB perf.data (9 samples) ]

  $ perf evlist -v | tr ',' '\n' | grep -e exclude -e precise
   precise_ip: 3

But having lower 'p' modifier set the bit for some reason.

  $ perf record -e cycles:pp true
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.002 MB perf.data (9 samples) ]

  $ perf evlist -v | tr ',' '\n' | grep -e exclude -e precise
   precise_ip: 2
   exclude_guest: 1

Actually AMD IBS suffers from this because it doesn't support excludes
and having this bit effectively disables new features in the current
implementation (due to the missing feature check).

  $ grep -m1 vendor /proc/cpuinfo
  vendor_id	: AuthenticAMD

  $ perf record -W -e cycles:p -vv true 2>&1 | grep switching
  switching off PERF_FORMAT_LOST support
  switching off weight struct support
  switching off bpf_event
  switching off ksymbol
  switching off cloexec flag
  switching off mmap2
  switching off exclude_guest, exclude_host

By not setting exclude_guest, we can fix this inconsistency and the
troubles.

Subject: [PATCH 1056/2948] perf tools: Detect missing kernel features properly

The evsel__detect_missing_features() is to check if the attributes of
the evsel is supported or not.  But it checks the attribute based on the
given evsel, it might miss something if the attr doesn't have the bit or
give incorrect results if the event is special.

Also it maintains the order of the feature that was added to the kernel
which means it can assume older features should be supported once it
detects the current feature is working.  To minimized the confusion and
to accurately check the kernel features, I think it's better to use a
software event and go through all the features at once.

Also make the function static since it's only used in evsel.c.

Subject: [PATCH 1057/2948] perf tools: Move x86__is_amd_cpu() to util/env.c

It can be called from non-x86 platform so let's move it to the general
util directory.  Also add a new helper perf_env__is_x86_amd_cpu() so
that it can be called with an existing perf_env as well.

Subject: [PATCH 1058/2948] perf tools: Check fallback error and order

The perf_event_open might fail due to various reasons, so blindly
reducing precise_ip level might not be the best way to deal with it.

It seems the kernel return -EOPNOTSUPP when PMU doesn't support the
given precise level.  Let's try again with the correct error code.

This caused a problem on AMD, as it stops on precise_ip of 2 for IBS but
user events with exclude_kernel=1 cannot make progress.  Let's add the
evsel__handle_error_quirks() to this case specially.  I plan to work on
the kernel side to improve this situation but it'd still need some
special handling for IBS.

Subject: [PATCH 1061/2948] rust: block: fix formatting of
 `kernel::block::mq::request` module

Fix several issues with rustdoc formatting for the
`kernel::block::mq::Request` module, in particular:

  - An ordered list not rendering correctly, fixed by using numbers
    prefixes instead of letters.

  - Code snippets formatted as regular text, fixed by wrapping the
    code with `back-ticks`.

  - References to types missing intra-doc links, fixed by wrapping the
    types with [square brackets].

Subject: [PATCH 1062/2948] Documentation: ABI: added filter mode doc in
 sysfs-bus-iio

The filter mode / filter type property is used for ad4130
and ad7779 drivers, therefore the ABI doc file for ad4130
was removed, merging both of them in the sysfs-bus-iio.
Since one of the drivers is available from 6.1, the version
has been set to 6.1 for these attributes.

automatically free 'state' when the device is removed. Drop the
kfree(state) calls from the probe error paths and the remove functions
accordingly.

Subject: [PATCH 1066/2948] PCI/ASPM: Disable L1 before disabling L1 PM
 Substates

PCIe r6.2, sec 5.5.4, requires that:

  If setting either or both of the enable bits for ASPM L1 PM Substates,
  both ports must be configured as described in this section while ASPM L1
  is disabled.

Previously, pcie_config_aspm_l1ss() assumed that "setting enable bits"
meant "setting them to 1", and it configured L1SS as follows:

  - Clear L1SS enable bits
  - Disable L1
  - Configure L1SS enable bits as required
  - Enable L1 if required

With this sequence, when disabling L1SS on an ARM A-core with a Synopsys
DesignWare PCIe core, the CPU occasionally hangs when reading
PCI_L1SS_CTL1, leading to a reboot when the CPU watchdog expires.

Move the L1 disable to the caller (pcie_config_aspm_link(), where L1 was
already enabled) so L1 is always disabled while updating the L1SS bits:

  - Disable L1
  - Clear L1SS enable bits
  - Configure L1SS enable bits as required
  - Enable L1 if required

Change pcie_aspm_cap_init() similarly.

Subject: [PATCH 1067/2948] dmaengine: loongson2-apb: Rename the prefix ls2x to
 loongson2

Since commit e06c43231214 ("dmaengine: Loongson1: Add Loongson-1 APB DMA
driver"), the Loongson-1 dma controller was added.

Unfortunately their naming has not been standardized, as CPUs belonging
to the same Loongson family, we expect to standardize the naming for
ease of understanding.

Subject: [PATCH 1068/2948] kfifo: don't include dma-mapping.h in kfifo.h

Nothing in kfifo.h directly needs dma-mapping.h, only two macros
use DMA_MAPPING_ERROR when actually instantiated.  Drop the
dma-mapping.h include to reduce include bloat.

Add an explicity <linux/io.h> include to drivers/mailbox/omap-mailbox.c
as that file uses __raw_readl and __raw_writel through a complicated
include chain involving <linux/dma-mapping.h>

Since __attribute__((naked)) cannot be used with functions

it needs in assembly directly.

While at it, fix the stack usage ("1 + 2*x - 1" is odd) and
document what it must do, and why it must adjust the stack.

Subject: [PATCH 1070/2948] um: restore process name

After the execve() to disable ASLR, comm is now "exe",
which is a bit confusing. Use readlink() to get this
to the right name again.

Disable stack frame size warnings on main.o since it's
part of the initial userspace and can use larger stack.

Subject: [PATCH 1071/2948] um: remove fault_catcher infrastructure

This was perhaps intended to do _nofault copies, but the
real reason is lost to history. Remove this, it's not
needed, and using longjmp() out of the middle of the
signal handler with all the state it has modified is
not going to be a good idea anyway.

Subject: [PATCH 1072/2948] um: Remove UML specific debug parameter

It does nothing but emit a warning when 'debug' is provided in the
kernel command line. It can be a bit annoying, as 'debug' is also a
valid kernel parameter to enable kernel debugging.

Subject: [PATCH 1082/2948] um: Abandon the _PAGE_NEWPROT bit

When a PTE is updated in the page table, the _PAGE_NEWPAGE bit will
always be set. And the corresponding page will always be mapped or
unmapped depending on whether the PTE is present or not. The check
on the _PAGE_NEWPROT bit is not really reachable. Abandoning it will
allow us to simplify the code and remove the unreachable code.

Subject: [PATCH 1083/2948] um: Rename _PAGE_NEWPAGE to _PAGE_NEEDSYNC

The _PAGE_NEWPAGE bit does not really indicate that this is a new page,
but rather whether this entry needs to be synced or not. Renaming it
to _PAGE_NEEDSYNC will make it more clear how everything ties together.

Subject: [PATCH 1084/2948] um: insert scheduler ticks when userspace does not
 yield

In time-travel mode userspace can do a lot of work without any time
passing. Unfortunately, this can result in OOM situations as the RCU
core code will never be run.

Work around this by keeping track of userspace processes that do not
yield for a lot of operations. When this happens, insert a jiffie into
the sched_clock clock to account time against the process and cause the
bookkeeping to run.

As sched_clock is used for tracing, it is useful to keep it in sync
between the different VMs. As such, try to remove added ticks again when
the actual clock ticks.

Subject: [PATCH 1085/2948] pinctrl: imx-scmi: Drop obsolete dependency on
 COMPILE_TEST

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), OF
can be enabled on all architectures. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

As ARM_SCMI_PROTOCOL already depends on COMPILE_TEST, we also don't
need to add COMPILE_TEST as an alternative dependency for it.

Subject: [PATCH 1086/2948] dt-bindings: pinctrl: fsl,imx6ul-pinctrl: Convert
 i.MX35/5x/6 to YAML

The IOMUXC controller description is almost identical on i.MX35/5x/6 SoCs,
except for the configuration bits which differ across SoCs. Rename the
fsl,imx6ul-pinctrl.yaml to fsl,imx35-pinctrl.yaml, fill in compatible
strings for the other SoCs and fill in the various bits into desciption.
This way, i.MX35/5x/6 series SoCs can all be converted to DT schema.
Remove the old text DT bindings description.

Subject: [PATCH 1087/2948] pinmux: Use sequential access to access
 desc->pinmux data

When two client of the same gpio call pinctrl_select_state() for the
same functionality, we are seeing NULL pointer issue while accessing
desc->mux_owner.

Let's say two processes A, B executing in pin_request() for the same pin
and process A updates the desc->mux_usecount but not yet updated the
desc->mux_owner while process B see the desc->mux_usecount which got
updated by A path and further executes strcmp and while accessing
desc->mux_owner it crashes with NULL pointer.

Serialize the access to mux related setting with a mutex lock.

	cpu0 (process A)			cpu1(process B)

pinctrl_select_state() {		  pinctrl_select_state() {
  pin_request() {				pin_request() {
  ...
						 ....
    } else {
         desc->mux_usecount++;
    						desc->mux_usecount && strcmp(desc->mux_owner, owner)) {

         if (desc->mux_usecount > 1)
               return 0;
         desc->mux_owner = owner;

  }						}

Subject: [PATCH 1088/2948] um: switch to regset API and depend on XSTATE

The PTRACE_GETREGSET API has now existed since Linux 2.6.33. The XSAVE
CPU feature should also be sufficiently common to be able to rely on it.

With this, define our internal FP state to be the hosts XSAVE data. Add
discovery for the hosts XSAVE size and place the FP registers at the end
of task_struct so that we can adjust the size at runtime.

Next we can implement the regset API on top and update the signal
handling as well as ptrace APIs to use them. Also switch coredump
creation to use the regset API and finally set HAVE_ARCH_TRACEHOOK.

This considerably improves the signal frames. Previously they might not
have contained all the registers (i386) and also did not have the
sizes and magic values set to the correct values to permit userspace to
decode the frame.

As a side effect, this will permit UML to run on hosts with newer CPU
extensions (such as AMX) that need even more register state.

Subject: [PATCH 1089/2948] Documentation PCI: Reformat RMW ops documentation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extract the list of RMW protected PCIe Capability registers into a
bullet list to make them easier to pick up on a glance. An upcoming
change is going to add one more register among them so it will be much
cleaner to have them as bullets.

Subject: [PATCH 1090/2948] PCI: Protect Link Control 2 Register with RMW
 locking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PCIe Bandwidth Controller performs RMW accesses the Link Control 2
Register which can occur concurrently to other sources of Link Control 2
Register writes. Therefore, add Link Control 2 Register among the PCI
Express Capability Registers that need RMW locking.

 free disasm_line

symbol__disassemble_capstone_powerpc() goto the 'err' label when it
failed in the loop that created disasm_line, and then used free()
directly to free disasm_line. Since the structure disasm_line contains
members that allocate memory dynamically, this can result in a memory
leak. In fact, we can simply break the loop when it fails in the middle
of the loop, and disasm_line__free() will then be called to properly
free the created line. Other error paths do not need to consider freeing
disasm_line.

Evidently, PATH_MAX isn't always defined, at least not via <limits.h>.
Simply remove the use and replace it by a constant 4k. As stat::st_size
is zero for /proc/self/exe we can't even size it automatically, and it
seems unlikely someone's going to try to run UML with such a path.

Subject: [PATCH 1096/2948] selftests: add new kallsyms selftests

We lack find_symbol() selftests, so add one. This let's us stress test
improvements easily on find_symbol() or optimizations. It also inherently
allows us to test the limits of kallsyms on Linux today.

We test a pathalogical use case for kallsyms by introducing modules
which are automatically written for us with a larger number of symbols.
We have 4 kallsyms test modules:

A: has KALLSYSMS_NUMSYMS exported symbols
B: uses one of A's symbols
C: adds KALLSYMS_SCALE_FACTOR * KALLSYSMS_NUMSYMS exported
D: adds 2 * the symbols than C

By using anything much larger than KALLSYSMS_NUMSYMS as 10,000 and
KALLSYMS_SCALE_FACTOR of 8 we segfault today. So we're capped at
around 160000 symbols somehow today. We can inpsect that issue at
our leasure later, but for now the real value to this test is that
this will easily allow us to test improvements on find_symbol().

We want to enable this test on allyesmodconfig builds so we can't
use this combination, so instead just use a safe value for now and
be informative on the Kconfig symbol documentation about where our
thresholds are for testers. We default then to KALLSYSMS_NUMSYMS of
just 100 and KALLSYMS_SCALE_FACTOR of 8.

On x86_64 we can use perf, for other architectures we just use 'time'
and allow for customizations. For example a future enhancements could
be done for parisc to check for unaligned accesses which triggers a
special special exception handler assembler code inside the kernel.
The negative impact on performance is so large on parisc that it
keeps track of its accesses on /proc/cpuinfo as UAH:

IRQ:       CPU0       CPU1
3:       1332          0         SuperIO  ttyS0
7:    1270013          0         SuperIO  pata_ns87415
64:  320023012  320021431             CPU  timer
65:   17080507   20624423             CPU  IPI
UAH:   10948640      58104   Unaligned access handler traps

While at it, this tidies up lib/ test modules to allow us to have
a new directory for them. The amount of test modules under lib/
is insane.

This should also hopefully showcase how to start doing basic
self module writing code, which may be more useful for more complex
cases later in the future.

+	  This allows us to stress test find_symbol() through the kallsyms
+	  used to place symbols on the kernel ELF kallsyms and modules kallsyms
+	  where we place kernel symbols such as exported symbols.
+
+	  We have four test modules:
+
+	  A: has KALLSYSMS_NUMSYMS exported symbols
+	  B: uses one of A's symbols
+	  C: adds KALLSYMS_SCALE_FACTOR * KALLSYSMS_NUMSYMS exported
+	  D: adds 2 * the symbols than C
+
+	  We stress test find_symbol() through two means:
+
+	  1) Upon load of B it will trigger simplify_symbols() to look for the
+	  one symbol it uses from the module A with tons of symbols. This is an
+	  indirect way for us to have B call resolve_symbol_wait() upon module
+	  load. This will eventually call find_symbol() which will eventually
+	  try to find the symbols used with find_exported_symbol_in_section().
+	  find_exported_symbol_in_section() uses bsearch() so a binary search
+	  for each symbol. Binary search will at worst be O(log(n)) so the
+	  larger TEST_MODULE_KALLSYSMS the worse the search.
+
+	  2) The selftests should load C first, before B. Upon B's load towards
+	  the end right before we call module B's init routine we get
+	  complete_formation() called on the module. That will first check
+	  for duplicate symbols with the call to verify_exported_symbols().
+	  That is when we'll force iteration on module C's insane symbol list.
+	  Since it has 10 * KALLSYMS_NUMSYMS it means we can first test
+	  just loading B without C. The amount of time it takes to load C Vs
+	  B can give us an idea of the impact growth of the symbol space and
+	  give us projection. Module A only uses one symbol from B so to allow
+	  this scaling in module C to be proportional, if it used more symbols
+	  then the first test would be doing more and increasing just the
+	  search space would be slightly different. The last module, module D
+	  will just increase the search space by twice the number of symbols in
+	  C so to allow for full projects.
+
+	  tools/testing/selftests/module/find_symbol.sh
+
+	  The current defaults will incur a build delay of about 7 minutes
+	  on an x86_64 with only 8 cores. Enable this only if you want to
+	  stress test find_symbol() with thousands of symbols. At the same
+	  time this is also useful to test building modules with thousands of
+	  symbols, and if BTF is enabled this also stress tests adding BTF
+	  information for each module. Currently enabling many more symbols
+	  will segfault the build system.

Subject: [PATCH 1099/2948] riscv: Add ISA extension parsing for pointer
 masking

The RISC-V Pointer Masking specification defines three extensions:
Smmpm, Smnpm, and Ssnpm. Add support for parsing each of them. The
specific extension which provides pointer masking support to userspace
(Supm) depends on the kernel's privilege mode, so provide a macro to
abstract this selection.

Smmpm implies the existence of the mseccfg CSR. As it is the only user
of this CSR so far, there is no need for an Xlinuxmseccfg extension.

Pointer masking is controlled via a two-bit PMM field, which appears in
various CSRs depending on which extensions are implemented. Smmpm adds
the field to mseccfg; Smnpm adds the field to menvcfg; Ssnpm adds the
field to senvcfg. If the H extension is implemented, Ssnpm also defines
henvcfg.PMM and hstatus.HUPMM.

Subject: [PATCH 1101/2948] riscv: Add support for userspace pointer masking

RISC-V supports pointer masking with a variable number of tag bits
(which is called "PMLEN" in the specification) and which is configured
at the next higher privilege level.

Wire up the PR_SET_TAGGED_ADDR_CTRL and PR_GET_TAGGED_ADDR_CTRL prctls
so userspace can request a lower bound on the number of tag bits and
determine the actual number of tag bits. As with arm64's
PR_TAGGED_ADDR_ENABLE, the pointer masking configuration is
thread-scoped, inherited on clone() and fork() and cleared on execve().

+Pointer masking
+---------------
+
+Support for pointer masking in userspace (the Supm extension) is provided via
+the ``PR_SET_TAGGED_ADDR_CTRL`` and ``PR_GET_TAGGED_ADDR_CTRL`` ``prctl()``
+operations. Pointer masking is disabled by default. To enable it, userspace
+must call ``PR_SET_TAGGED_ADDR_CTRL`` with the ``PR_PMLEN`` field set to the
+number of mask/tag bits needed by the application. ``PR_PMLEN`` is interpreted
+as a lower bound; if the kernel is unable to satisfy the request, the
+``PR_SET_TAGGED_ADDR_CTRL`` operation will fail. The actual number of tag bits
+is returned in ``PR_PMLEN`` by the ``PR_GET_TAGGED_ADDR_CTRL`` operation.

Subject: [PATCH 1102/2948] riscv: Add support for the tagged address ABI

When pointer masking is enabled for userspace, the kernel can accept
tagged pointers as arguments to some system calls. Allow this by
untagging the pointers in access_ok() and the uaccess routines. The
uaccess routines must peform untagging in software because U-mode and
S-mode have entirely separate pointer masking configurations. In fact,
hardware may not even implement pointer masking for S-mode.

Since the number of tag bits is variable, untagged_addr_remote() needs
to know what PMLEN to use for the remote mm. Therefore, the pointer
masking mode must be the same for all threads sharing an mm. Enforce
this with a lock flag in the mm context, as x86 does for LAM. The flag
gets reset in init_new_context() during fork(), as the new mm is no
longer multithreaded.

Subject: [PATCH 1104/2948] riscv: selftests: Add a pointer masking test

This test covers the behavior of the PR_SET_TAGGED_ADDR_CTRL and
PR_GET_TAGGED_ADDR_CTRL prctl() operations, their effects on the
userspace ABI, and their effects on the system call ABI.

Subject: [PATCH 1105/2948] riscv: hwprobe: Export the Supm ISA extension

Supm is a virtual ISA extension defined in the RISC-V Pointer Masking
specification, which indicates that pointer masking is available in
U-mode. It can be provided by either Smnpm or Ssnpm, depending on which
mode the kernel runs in. Userspace should not care about this
distinction, so export Supm instead of either underlying extension.

Hide the extension if the kernel was compiled without support for the
pointer masking prctl() interface.

Subject: [PATCH 1106/2948] RISC-V: KVM: Allow Smnpm and Ssnpm extensions for
 guests

The interface for controlling pointer masking in VS-mode is henvcfg.PMM,
which is part of the Ssnpm extension, even though pointer masking in
HS-mode is provided by the Smnpm extension. As a result, emulating Smnpm
in the guest requires (only) Ssnpm on the host.

The guest configures Smnpm through the SBI Firmware Features extension,
which KVM does not yet implement, so currently the ISA extension has no
visible effect on the guest, and thus it cannot be disabled. Ssnpm is
configured using the senvcfg CSR within the guest, so that extension
cannot be hidden from the guest without intercepting writes to the CSR.

 thread/process

Since we have a helper now, let's switch to using it. It will make
the code slightly more consistent.

Subject: [PATCH 1116/2948] fuse: enable dynamic configuration of fuse max
 pages limit (FUSE_MAX_MAX_PAGES)

Introduce the capability to dynamically configure the max pages limit
(FUSE_MAX_MAX_PAGES) through a sysctl. This allows system administrators
to dynamically set the maximum number of pages that can be used for
servicing requests in fuse.

Previously, this is gated by FUSE_MAX_MAX_PAGES which is statically set
to 256 pages. One result of this is that the buffer size for a write
request is limited to 1 MiB on a 4k-page system.

The default value for this sysctl is the original limit (256 pages).

$ sysctl -a | grep max_pages_limit
fs.fuse.max_pages_limit = 256

$ sysctl -n fs.fuse.max_pages_limit
256

$ echo 1024 | sudo tee /proc/sys/fs/fuse/max_pages_limit
1024

$ sysctl -n fs.fuse.max_pages_limit
1024

$ echo 65536 | sudo tee /proc/sys/fs/fuse/max_pages_limit
tee: /proc/sys/fs/fuse/max_pages_limit: Invalid argument

Subject: [PATCH 1117/2948] fuse: remove useless IOCB_DIRECT in
 fuse_direct_read/write_iter

Commit 23c94e1cdcbf ("fuse: Switch to using async direct IO
for FOPEN_DIRECT_IO") gave the async direct IO code path in the
fuse_direct_read_iter() and fuse_direct_write_iter(). But since
these two functions are only called under FOPEN_DIRECT_IO is set,
it seems that we can also use the async direct IO even the flag
IOCB_DIRECT is not set to enjoy the async direct IO method. Also
move the definition of fuse_io_priv to where it is used in fuse_
direct_write_iter.

  ---[ end trace 0000000000000000 ]---

The warning is triggered as follows:

1) syscall finit_module() handles the module insertion and it invokes
kernel_read_file() to read the content of the module first.

2) kernel_read_file() allocates a 10MB buffer by using vmalloc() and
passes it to kernel_read(). kernel_read() constructs a kvec iter by
using iov_iter_kvec() and passes it to fuse_file_read_iter().

3) virtio-fs disables the cache, so fuse_file_read_iter() invokes
fuse_direct_io(). As for now, the maximal read size for kvec iter is
only limited by fc->max_read. For virtio-fs, max_read is UINT_MAX, so
fuse_direct_io() doesn't split the 10MB buffer. It saves the address and
the size of the 10MB-sized buffer in out_args[0] of a fuse request and
passes the fuse request to virtio_fs_wake_pending_and_unlock().

4) virtio_fs_wake_pending_and_unlock() uses virtio_fs_enqueue_req() to
queue the request. Because virtiofs need DMA-able address, so
virtio_fs_enqueue_req() uses kmalloc() to allocate a bounce buffer for
all fuse args, copies these args into the bounce buffer and passed the
physical address of the bounce buffer to virtiofsd. The total length of
these fuse args for the passed fuse request is about 10MB, so
copy_args_to_argbuf() invokes kmalloc() with a 10MB size parameter and
it triggers the warning in __alloc_pages():

	if (WARN_ON_ONCE_GFP(order > MAX_PAGE_ORDER, gfp))
		return NULL;

5) virtio_fs_enqueue_req() will retry the memory allocation in a
kworker, but it won't help, because kmalloc() will always return NULL
due to the abnormal size and finit_module() will hang forever.

A feasible solution is to limit the value of max_read for virtio-fs, so
the length passed to kmalloc() will be limited. However it will affect
the maximal read size for normal read. And for virtio-fs write initiated
from kernel, it has the similar problem but now there is no way to limit
fc->max_write in kernel.

So instead of limiting both the values of max_read and max_write in
kernel, introducing use_pages_for_kvec_io in fuse_conn and setting it as
true in virtiofs. When use_pages_for_kvec_io is enabled, fuse will use
pages instead of pointer to pass the KVEC_IO data.

After switching to pages for KVEC_IO data, these pages will be used for
DMA through virtio-fs. If these pages are backed by vmalloc(),
{flush|invalidate}_kernel_vmap_range() are necessary to flush or
invalidate the cache before the DMA operation. So add two new fields in
fuse_args_pages to record the base address of vmalloc area and the
condition indicating whether invalidation is needed. Perform the flush
in fuse_get_user_pages() for write operations and the invalidation in
fuse_release_user_pages() for read operations.

It may seem necessary to introduce another field in fuse_conn to
indicate that these KVEC_IO pages are used for DMA, However, considering
that virtio-fs is currently the only user of use_pages_for_kvec_io, just
reuse use_pages_for_kvec_io to indicate that these pages will be used
for DMA.

Subject: [PATCH 1119/2948] virtiofs: use GFP_NOFS when enqueuing request
 through kworker

When invoking virtio_fs_enqueue_req() through kworker, both the
allocation of the sg array and the bounce buffer still use GFP_ATOMIC.
Considering the size of the sg array may be greater than PAGE_SIZE, use
GFP_NOFS instead of GFP_ATOMIC to lower the possibility of memory
allocation failure and to avoid unnecessarily depleting the atomic
reserves. GFP_NOFS is not passed to virtio_fs_enqueue_req() directly,
GFP_KERNEL and memalloc_nofs_{save|restore} helpers are used instead.

It may seem OK to pass GFP_NOFS to virtio_fs_enqueue_req() as well when
queuing the request for the first time, but this is not the case. The
reason is that fuse_request_queue_background() may call
->queue_request_and_unlock() while holding fc->bg_lock, which is a
spin-lock. Therefore, still use GFP_ATOMIC for it.

Subject: [PATCH 1121/2948] fuse: convert readahead to use folios

Currently we're using the __readahead_batch() helper which populates our
fuse_args_pages->pages array with pages.  Convert this to use the newer
folio based pattern which is to call readahead_folio() to get the next
folio in the read ahead batch.  I've updated the code to use things like
folio_size() and to take into account larger folio sizes, but this is
purely to make that eventual work easier to do, we currently will not
get large folios so this is more future proofing than actual support.

[SzM: remove check for readahead_folio() won't return NULL (at least for
now) so remove ugly assign in conditional.]

Now that the buffered write path is using folios, convert
fuse_do_readpage() to take a folio instead of a page, update it to use
the appropriate folio helpers, and update the callers to pass in the
folio directly instead of a page.

fuse_writepage_need_send is called by fuse_writepages_fill() which
already has a folio.  Change fuse_writepage_need_send() to take a folio
instead, add a helper to check if the folio range is under writeback and
use this, as well as the appropriate folio helpers in the rest of the
function.  Update fuse_writepage_need_send() to pass in the folio
directly.

update the places where we update the vmstat counters for writeback to

already have the folio, on the dec side we have to page_folio() the

The MCQ code is also valid for legacy mode. Hence, remove the legacy
mode code and retain the MCQ code. Since it is not an error if a command
completes while ufshcd_try_to_abort_task() is in progress, use
dev_info() instead of dev_err() to report this.

Subject: [PATCH 1137/2948] scsi: ufs: core: Simplify
 ufshcd_exception_event_handler()

The ufshcd_scsi_block_requests() and ufshcd_scsi_unblock_requests()
calls were introduced in ufshcd_exception_event_handler() to prevent
that querying the exception event information would time out. Commit
10fe5888a40e ("scsi: ufs: increase the scsi query response timeout")
increased the timeout for querying exception information from 30 ms to
1.5 s and thereby eliminated the risk that a timeout would happen.
Hence, the calls to block and unblock SCSI requests are superfluous.
Remove these calls.

Subject: [PATCH 1140/2948] scsi: ufs: core: Remove redundant host_lock calls
 around UTMRLDBR

There is no need to serialize single read/write calls to the host
controller registers. Remove the redundant host_lock calls that protect
access to the task management doorbell register: UTMRLDBR.

The comment /* UFSHCD_QUIRK_REINIT_AFTER_MAX_GEAR_SWITCH is set */ is
only correct if ufshcd_device_init() is only called by
ufshcd_probe_hba().  Convert the comment into an explicit check. This
patch prepares for moving the ufshcd_device_init() calls.

Subject: [PATCH 1149/2948] scsi: ufs: core: Move the ufshcd_device_init(hba,
 true) call

ufshcd_async_scan() is called (asynchronously) only by ufshcd_init().
Move the ufshcd_device_init(hba, true) call from ufshcd_async_scan()
into ufshcd_init(). This patch prepares for moving both scsi_add_host()
calls into ufshcd_add_scsi_host(). Calling ufshcd_device_init() from
ufshcd_init() without holding hba->host_sem is safe. This is safe
because hba->host_sem serializes core code and sysfs callbacks. The
ufshcd_device_init() call is moved before the scsi_add_host() call and
hence happens before any SCSI sysfs attributes are created.

Since ufshcd_device_init() may call scsi_add_host(), only call
scsi_add_host() from ufshcd_add_scsi_host() if the SCSI host has not yet
been added by ufshcd_device_init().

Subject: [PATCH 1154/2948] um: fix stub exe build with CONFIG_GCOV

CONFIG_GCOV is special and only in UML since it builds the
kernel with a "userspace" option. This is fine, but the stub
is even more special and not really a full userspace process,
so it then fails to link as reported.

Remove the GCOV options from the stub build.

For good measure, also remove the GPROF options, even though
they don't seem to cause build failures now.

To be able to do this, export the specific options (GCOV_OPT
and GPROF_OPT) but rename them so there's less chance of any
conflicts.

Closes: https://lore.kernel.org/oe-kbuild-all/202410242238.SXhs2kQ4-lkp@intel.com/

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Clear the address mapped (outbound_addr array) in dw_pcie_ep_unmap_addr(),
to ensure that dw_pcie_find_index() does not match an ATU index that was
already unmapped.

This is in addition to clearing the ATU index bit in ob_window_map.

Subject: [PATCH 1159/2948] memblock: uniformly initialize all reserved pages
 to MIGRATE_MOVABLE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently when CONFIG_DEFERRED_STRUCT_PAGE_INIT is not set, the reserved
pages are initialized to MIGRATE_MOVABLE by default in memmap_init.

Reserved memory mainly store the metadata of struct page. When
HUGETLB_PAGE_OPTIMIZE_VMEMMAP_DEFAULT_ON=Y and hugepages are allocated,
the HVO will remap the vmemmap virtual address range to the page which
vmemmap_reuse is mapped to. The pages previously mapping the range will
be freed to the buddy system.

Before this patch:
when CONFIG_DEFERRED_STRUCT_PAGE_INIT is not set, the freed memory was
placed on the Movable list;
When CONFIG_DEFERRED_STRUCT_PAGE_INIT=Y, the freed memory was placed on
the Unmovable list.

After this patch, the freed memory is placed on the Movable list
regardless of whether CONFIG_DEFERRED_STRUCT_PAGE_INIT is set.

Eg:
Tested on a virtual machine(1000GB):
Intel(R) Xeon(R) Platinum 8358P CPU

-        chip connected with the corresponding spi address set. For example if
-        you have a chip with address 3 connected, you have to set bit3 to 1,
-        which is 0x08. mcp23s08 chip variant only supports bits 0-3. It is not
-        possible to mix mcp23s08 and mcp23s17 on the same chipselect. Set at
-        least one bit to 1 for SPI chips.
-    NOTE: Do not use the old mcp prefix any more. It is deprecated and will be
-    removed.
-- spi-max-frequency = The maximum frequency this chip is able to handle
-
-Optional properties:
-- #interrupt-cells : Should be two.
-  - first cell is the pin number
-  - second cell is used to specify flags.
-- interrupt-controller: Marks the device node as a interrupt controller.
-- drive-open-drain: Sets the ODR flag in the IOCON register. This configures
-        the IRQ output as open drain active low.
-- reset-gpios: Corresponds to the active-low RESET# pin for the chip
-
-Optional device specific properties:
-- microchip,irq-mirror: Sets the mirror flag in the IOCON register. Devices
-        with two interrupt outputs (these are the devices ending with 17 and
-        those that have 16 IOs) have two IO banks: IO 0-7 form bank 1 and
-        IO 8-15 are bank 2. These chips have two different interrupt outputs:
-        One for bank 1 and another for bank 2. If irq-mirror is set, both
-        interrupts are generated regardless of the bank that an input change
-        occurred on. If it is not set, the interrupt are only generated for the
-        bank they belong to.
-        On devices with only one interrupt output this property is useless.
-- microchip,irq-active-high: Sets the INTPOL flag in the IOCON register. This
-        configures the IRQ output polarity as active high.
-
-Example I2C (with interrupt):
-gpiom1: gpio@20 {
-        compatible = "microchip,mcp23017";
-        gpio-controller;
-        #gpio-cells = <2>;
-        reg = <0x20>;
-
-        interrupt-parent = <&gpio1>;
-        interrupts = <17 IRQ_TYPE_LEVEL_LOW>;
-        interrupt-controller;
-        #interrupt-cells=<2>;
-        microchip,irq-mirror;
-};
-
-Example SPI:
-gpiom1: gpio@0 {
-        compatible = "microchip,mcp23s17";
-        gpio-controller;
-        #gpio-cells = <2>;
-        microchip,spi-present-mask = <0x01>;
-        reg = <0>;
-        spi-max-frequency = <1000000>;
-};
-
-Pull-up configuration
-=====================
-
-If pins are used as output, they can also be configured with pull-ups. This is
-done with pinctrl.
-
-Please refer file <devicetree/bindings/pinctrl/pinctrl-bindings.txt>
-for details of the common pinctrl bindings used by client devices,
-including the meaning of the phrase "pin configuration node".
-
-Optional Pinmux properties:
---------------------------
-Following properties are required if default setting of pins are required
-at boot.
-- pinctrl-names: A pinctrl state named per <pinctrl-bindings.txt>.
-- pinctrl[0...n]: Properties to contain the phandle for pinctrl states per
-		<pinctrl-bindings.txt>.
-
-The pin configurations are defined as child of the pinctrl states node. Each
-sub-node have following properties:
-
-Required properties:
-------------------
-- pins: List of pins. Valid values of pins properties are:
-		      gpio0 ... gpio7 for the devices with 8 GPIO pins and
-		      gpio0 ... gpio15 for the devices with 16 GPIO pins.
-
-Optional properties:
--------------------
-The following optional property is defined in the pinmux DT binding document
-<pinctrl-bindings.txt>. Absence of this property will leave the configuration
-in its default state.
-	bias-pull-up
-
-Example with pinctrl to pull-up output pins:
-gpio21: gpio@21 {
-	compatible = "microchip,mcp23017";
-	gpio-controller;
-	#gpio-cells = <0x2>;
-	reg = <0x21>;
-	interrupt-parent = <&socgpio>;
-	interrupts = <0x17 0x8>;
-	interrupt-names = "mcp23017@21 irq";
-	interrupt-controller;
-	#interrupt-cells = <0x2>;
-	microchip,irq-mirror;
-	pinctrl-names = "default";
-	pinctrl-0 = <&i2cgpio0irq>, <&gpio21pullups>;
-	reset-gpios = <&gpio6 15 GPIO_ACTIVE_LOW>;
-
-	gpio21pullups: pinmux {
-		pins =	"gpio0", "gpio1", "gpio2", "gpio3",
-			"gpio4", "gpio5", "gpio6", "gpio7",
-			"gpio8", "gpio9", "gpio10", "gpio11",
-			"gpio12", "gpio13", "gpio14", "gpio15";
-		bias-pull-up;

Subject: [PATCH 1162/2948] pinctrl: spacemit: fix double free of map

The map pointer is freed by pinctrl_utils_free_map().  It must not be a
devm_ pointer or it leads to a double free when the device is unloaded.

This is similar to a couple bugs Harshit Mogalapalli fixed earlier in
commits 3fd976afe974 ("pinctrl: nuvoton: fix a double free in
ma35_pinctrl_dt_node_to_map_func()") and 4575962aeed6 ("pinctrl: sophgo:
fix double free in cv1800_pctrl_dt_node_to_map()").

Subject: [PATCH 1164/2948] tools subcmd: Add non-waitpid
 check_if_command_finished()

Using waitpid can cause stdout/stderr of the child process to be
lost. Use Linux's /prod/<pid>/status file to determine if the process
has reached the zombie state. Use the 'status' file rather than 'stat'
to avoid issues around skipping the process name.

Subject: [PATCH 1165/2948] perf test: Display number of active running tests

Before polling or sleeping to wait for a test to complete, print out
": Running (<num> active)" where the number of active tests is
determined by iterating over the tests and seeing which return false
for check_if_command_finished. The line erasing and printing out only
occur if the number of runnings tests changes to avoid the line
flickering excessively. Knowing tests are running allows a user to
know a test is running and in parallel mode how many of the tests are
waiting to complete. If color mode is disabled then avoid displaying
the "Running" message as deleting the line isn't reliable.

Subject: [PATCH 1167/2948] perf test: Avoid list test blocking on writing to
 stdout

Python's json.tool will output the input json to stdout. Redirect to
/dev/null to avoid blocking on stdout writes.

Subject: [PATCH 1168/2948] perf test: Tag parallel failing shell tests with
 "(exclusive)"

Some shell tests compete for resources and so can't run with other
tests, tag such tests.  The "(exclusive)" stems from shared/exclusive
to describe how the tests run as if holding a lock.

For ARM/coresight tests:

Add a signal handler around running a test. If a signal occurs during
the test a siglongjmp unwinds the stack and output is flushed. The
global run_test_jmp_buf is either unique per forked child or not
shared during sequential execution.

Subject: [PATCH 1170/2948] perf test: Run parallel tests in two passes

In pass 1 run all tests that succeed when run in parallel. In pass 2
sequentially run all remaining tests that are flagged as
"exclusive". Sequential and dont_fork tests keep to run in pass 1.
Read the exclusive flag from the shell test descriptions, but remove
from display to avoid >100 characters. Add error handling to finish
tests if starting a later test fails. Mark the task-exit test as
exclusive due to issues reported-by James Clark.

Subject: [PATCH 1171/2948] perf test: Make parallel testing the default

Now C tests can have the "exclusive" flag to run without other tests,
and shell tests can add "(exclusive)" to their description, run tests
in parallel by default. Tests which flake when run in parallel can be
marked exclusive to resolve the problem.

Non-scientifically, the reduction on `perf test` execution time is
from 8m35.890s to 3m55.115s on a Tigerlake laptop. So the tests
complete in less than half the time.

If the `perf test` process is killed the child tests continue running

signals to the running child processes so that they terminate when the
parent is killed.

Subject: [PATCH 1175/2948] drivers: iio: adc: add support for ad777x family

Add support for AD7770, AD7771, AD7779 ADCs. The device is capable of
sending out data both on DOUT lines interface,as on the SDO line.
The driver currently implements only the SDO data streaming mode. SPI
communication is used alternatively for accessing registers and streaming
data. Register accesses are protected by crc8.

Subject: [PATCH 1176/2948] dt-bindings: iio: light: opt3001: add compatible
 for opt3002

The opt3002 is a Light-to-Digital Sensor by TI with support for wide-range
spectrum light. It shares most properties with their opt3001 model with
the exception of having a wide spectral bandwidth, ranging from 300 nm
to 1000 nm.

Add the compatible string of opt3002.

Subject: [PATCH 1183/2948] iio: adc: ad7606: fix/persist oversampling_ratio
 setting

When the mutexes were reworked to guards, the caching of the
oversampling_ratio values was removed by accident.

The main effect of this change is that, after setting the
oversampling_ratio value, reading it back would result in the initial value
(of 1).
The value would get sent to the device correctly though.

Fixes 2956979dbd0d: ("iio: adc: ad7606: switch mutexes to guard")

Subject: [PATCH 1184/2948] iio: adc: ad7606: use realbits for sign-extending
 in scan_direct

Currently the 'ad7606' driver supports parts with 18 and 16 bits
resolutions.
But when adding support for AD7607 (which has a 14-bit resolution) we
should check for the 'realbits' field, to be able to sign-extend correctly.

Subject: [PATCH 1185/2948] iio: adc: ad7606: rework scale-available to be
 static
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The main driver for this change is the AD7607 part, which has a scale of
"1.220703" for the ±10V range. The AD7607 has a resolution of 14-bits.

So, just adding the scale-available list for that part would require some
quirks to handle just that scale value.
But to do it more neatly, the best approach is to rework the scale
available lists to have the same format as it is returned to userspace.
That way, we can also get rid of the allocation for the 'scale_avail_show'
array.

The AD7607, AD7608 and AD7609 are some older parts of the AD7606 family.
They are hardware-only, meaning that they don't have any registers
accessible via SPI or Parallel interface.
They are more similar to the AD7605-4 part, which is supported by the
'ad7606' driver, and are configurable via GPIOs.

Like the AD7605-4 part, all 3 parts have 2 CONVST (Conversion Start) pins
(CONVST A and CONVST B). But in practice, these should be tied together to
make reading of samples easier via a serial line.

The AD7607 has an 14-bit resolution and AD7608 & AD7609 have an 18-bit
resolution. The main difference between the AD7608 & AD7609 is that the
AD7609 has a larger range (±10V & ±20V) vs the ±5V & ±10V ranges for AD7608.

However, unlike AD7605-4 part, these 3 parts have oversampling which is
configurable (like for the AD7606 in HW-mode) via GPIOs.

Subject: [PATCH 1192/2948] iio: acpi: Add iio_get_acpi_device_name_and_data()
 helper function

A few drivers duplicate the code to retrieve ACPI device instance name.
Some of them want an associated driver data as well.

In order of deduplication introduce the common helper functions.

The ACPI IDs are defined in the respective ID tables. Puting them
to the I²C ID legacy table has no meaning. Remove that ID.

Subject: [PATCH 1194/2948] iio: accel: kxcjk-1013: Revert "Add support for
 KX022-1020"

The mentioned change effectively broke the ODR startup timeouts
settungs for KX023-1025 case. Let's revert it for now and see
how we can handle it with the better approach after switching
the driver to use data structure instead of enum.

This reverts commit d5cbe1502043124ff8af8136b80f93758c4a61e0.

Subject: [PATCH 1195/2948] iio: accel: kxcjk-1013: Switch from CONFIG_PM
 guards to pm_ptr() etc

Letting the compiler remove these functions when the kernel is built
without CONFIG_PM support is simpler and less error prone than the
use of #ifdef based config guards.

Removing instances of this approach from IIO also stops them being
copied into new drivers.

Subject: [PATCH 1198/2948] iio: accel: kxcjk-1013: Start using chip_info
 variables instead of enum

Instead of having a enum and keeping IDs as driver data pointers,
just have a chip_info struct per supported device.

Subject: [PATCH 1204/2948] usb: dwc3: gadget: Refine the logic for resizing Tx
 FIFOs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The current logic is rigid, setting num_fifos to fixed values.
3 for any maxburst greater than 1.
tx_fifo_resize_max_num for maxburst greater than 6.
Additionally, it did not differentiate much between bulk and
isochronous transfers, applying similar logic to both.

The updated logic is more flexible and specifically designed to meet
the unique requirements of both bulk and isochronous transfers. We
have made every effort to satisfy all needs and requirements, verified
on our specific platform and application.

Bulk Transfers: Ensures that num_fifos is optimized by considering both
the maxburst and DT property "tx-fifo-max-num" for super speed and
above. For high-speed and below bulk endpoints, a 2K TxFIFO allocation
is used to meet efficient data transfer needs, considering
FIFO-constrained platforms.

Isochronous Transfers: Ensures that num_fifos is sufficient by
considering the maximum packet multiplier for HS and below and maxburst
for Super-speed and above eps, along with a constraint with the DT
property "tx-fifo-max-num".

This change aims to optimize the allocation of Tx FIFOs for both bulk
and isochronous endpoints, potentially improving data transfer efficiency
and overall performance. It also enhances support for all use cases,
which can be tweaked with DT parameters and the endpoint’s maxburst and
maxpacket. This structured approach ensures that the appropriate number
of FIFOs is allocated based on the endpoint type and USB speed.

Subject: [PATCH 1207/2948] dt-bindings: connector: Add properties to define
 time values

This commit adds the following properties:
  * sink-wait-cap-time-ms
  * ps-source-off-time-ms
  * cc-debounce-time-ms

This is to enable setting of platform/board specific timer values as
these timers have a range of acceptable values.

Subject: [PATCH 1208/2948] usb: typec: tcpm: Add support for parsing time dt
 properties

Add support for DT time properties to allow users to define platform
specific timing deadlines of certain timers rather than using hardcoded
ones. For values that have not been explicitly defined in DT using this
property, default values will be set therefore, making this change
backward compatible.

Subject: [PATCH 1210/2948] mm/kasan: Don't store metadata inside kmalloc
 object when slub_debug_orig_size is on

For a kmalloc object, when both kasan and slub redzone sanity check
are enabled, they could both manipulate its data space like storing
kasan free meta data and setting up kmalloc redzone, and may affect
accuracy of that object's 'orig_size'.

As an accurate 'orig_size' will be needed by some function like
krealloc() soon, save kasan's free meta data in slub's metadata area
instead of inside object when 'orig_size' is enabled.

This will make it easier to maintain/understand the code. Size wise,
when these two options are both enabled, the slub meta data space is
already huge, and this just slightly increase the overall size.

	if (... ||
	    WARN_ON(... ||
		    object_size - args->usersize < args->useroffset))
		args->usersize = args->useroffset = 0;
	...

Therefore, the WARN_ON() check in create_cache() can be safely removed.

Subject: [PATCH 1213/2948] mm, slab: add kerneldocs for common SLAB_ flags

We have many SLAB_ flags but many are used only internally, by kunit
tests or debugging subsystems cooperating with slab, or are set
according to slab_debug boot parameter.

Create kerneldocs for the commonly used flags that may be passed to
kmem_cache_create(). SLAB_TYPESAFE_BY_RCU already had a detailed
description, so turn it to a kerneldoc. Add some details for
SLAB_ACCOUNT, SLAB_RECLAIM_ACCOUNT and SLAB_HWCACHE_ALIGN. Reference
them from the __kmem_cache_create_args() kerneldoc.

Subject: [PATCH 1214/2948] SLUB: Add support for per object memory policies

The old SLAB allocator used to support memory policies on a per
allocation bases. In SLUB the memory policies are applied on a
per page frame / folio bases. Doing so avoids having to check memory
policies in critical code paths for kmalloc and friends.

This worked on general well on Intel/AMD/PowerPC because the
interconnect technology is mature and can minimize the latencies
through intelligent caching even if a small object is not
placed optimally.

However, on ARM we have an emergence of new NUMA interconnect
technology based more on embedded devices. Caching of remote content
can currently be ineffective using the standard building blocks / mesh
available on that platform. Such architectures benefit if each slab
object is individually placed according to memory policies
and other restrictions.

This patch adds another kernel parameter

    slab_strict_numa

If that is set then a static branch is activated that will cause
the hotpaths of the allocator to evaluate the current memory
allocation policy. Each object will be properly placed by
paying the price of extra processing and SLUB will no longer
defer to the page allocator to apply memory policies at the
folio level.

This patch improves performance of memcached running
on Ampere Altra 2P system (ARM Neoverse N1 processor)
by 3.6% due to accurate placement of small kernel objects.

guarantees on access alignment and fixes a sparse check warning. Switch
to memset_io() here.

Subject: [PATCH 1218/2948] remoteproc: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/remoteproc to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

Subject: [PATCH 1219/2948] iio: invensense: fix multiple odr switch when FIFO
 is off

When multiple ODR switch happens during FIFO off, the change could
not be taken into account if you get back to previous FIFO on value.
For example, if you run sensor buffer at 50Hz, stop, change to
200Hz, then back to 50Hz and restart buffer, data will be timestamped
at 200Hz. This due to testing against mult and not new_mult.

To prevent this, let's just run apply_odr automatically when FIFO is
off. It will also simplify driver code.

Update inv_mpu6050 and inv_icm42600 to delete now useless apply_odr.

Subject: [PATCH 1225/2948] perf probe: Fix retrieval of source files from a
 debuginfod server

When perf is linked with libdebuginfod:

  root@number:~# ldd ~/bin/perf | grep debuginfod
	libdebuginfod.so.1 => /lib64/libdebuginfod.so.1 (0x00007ff5c3930000)
  root@number:~# perf check feature debuginfod
            debuginfod: [ on  ]  # HAVE_DEBUGINFOD_SUPPORT
  root@number:~#

And we don't have a debuginfo package installed for the binary we're
trying to use, vmlinux in this case as we didn't specify any using 'perf
probe -x', it will use the build for the running kernel:

  root@number:~# perf buildid-list -k
  38e927fd7799d50dbc4d99ec5e3f781b6105a6a9
  root@number:~#

And communicate with a debuginfo server, be it configured in a
~/.perfconfig file, excerpt from the 'perf config' man page:

       buildid-cache.*
           buildid-cache.debuginfod=URLs Specify debuginfod URLs to be
	   used when retrieving perf.data binaries, it follows the same
	   syntax as the DEBUGINFOD_URLS variable, like:

               buildid-cache.debuginfod=http://192.168.122.174:8002

Or via the DEBUGINFOD_URLS env var, as distros like fedora do by
default:

  root@number:~# echo $DEBUGINFOD_URLS
  https://debuginfod.fedoraproject.org/
  root@number:~#

To pick and cache just what is needed, instead of requiring the manual
installation of the entire kernel-debuginfo package, which is really
large.

It will, in this example, use the following cache files, deleted
before/after this patch just to test the whole process:

  root@number:~# rm -f /root/.cache/debuginfod_client/38e927fd7799d50dbc4d99ec5e3f781b6105a6a9/source-a1414a5d-#usr#src#debug#kernel-6.11.4#linux-6.11.4-201.fc40.x86_64#net#ipv4#icmp.c
  root@number:~# rm -f /root/.cache/debuginfod_client/38e927fd7799d50dbc4d99ec5e3f781b6105a6a9/debuginfo

Before this patch:

  root@number:~# perf probe -L icmp_rcv
  Failed to find source file path.
    Error: Failed to show lines.
  root@number:~#

This is because 'perf probe' was using just the relative file name, in
this case "net/ipv4/icmp.c", that is where the 'icmp_rcv' function is
located, if we add it and comply with the debuginfo_find_source()
function man page, it contacts the server, finds the necessary files,
cache them locally and all works:

  root@number:~# perf probe -L icmp_rcv | head
  <icmp_rcv@/root/.cache/debuginfod_client/38e927fd7799d50dbc4d99ec5e3f781b6105a6a9/source-a1414a5d-#usr#src#debug#kernel-6.11.4#linux-6.11.4-201.fc40.x86_64#net#ipv4#icmp.c:0>
        0  int icmp_rcv(struct sk_buff *skb)
           {
        2  	enum skb_drop_reason reason = SKB_DROP_REASON_NOT_SPECIFIED;
           	struct rtable *rt = skb_rtable(skb);
           	struct net *net = dev_net(rt->dst.dev);
           	struct icmphdr *icmph;

           	if (!xfrm4_policy_check(NULL, XFRM_POLICY_IN, skb)) {
        8  		struct sec_path *sp = skb_sec_path(skb);

Subject: [PATCH 1226/2948] dt-bindings: arm: airoha: Add the chip-scu node for
 EN7581 SoC

This patch adds the chip-scu document bindings for EN7581 SoC.
The airoha chip-scu block provides a configuration interface for clock,
io-muxing and other functionalities used by multiple controllers (e.g.
clock, pinctrl, ecc.) on EN7581 SoC.

'struct kvm_device_ops' is not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.

On a x86_64, with allmodconfig:

Subject: [PATCH 1233/2948] vfio/qat: fix overflow check in
 qat_vf_resume_write()

The unsigned variable `size_t len` is cast to the signed type `loff_t`
when passed to the function check_add_overflow(). This function considers
the type of the destination, which is of type loff_t (signed),
potentially leading to an overflow. This issue is similar to the one
described in the link below.

Remove the cast.

Note that even if check_add_overflow() is bypassed, by setting `len` to
a value that is greater than LONG_MAX (which is considered as a negative
value after the cast), the function copy_from_user(), invoked a few lines
later, will not perform any copy and return `len` as (len > INT_MAX)
causing qat_vf_resume_write() to fail with -EFAULT.

Subject: [PATCH 1244/2948] PCI: Make pcim_iounmap_region() a public function

The function pcim_iounmap_regions() is problematic because it uses a
bitmask mechanism to release / iounmap multiple BARs at once. It, thus,
prevents getting rid of the problematic iomap table mechanism which was
deprecated in commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(),
pcim_iomap_regions_request_all()").

pcim_iounmap_region() does not have that problem. Make it public as the
successor of pcim_iounmap_regions().

Subject: [PATCH 1245/2948] PCI: Fix use-after-free of slot->bus on hot remove

Dennis reports a boot crash on recent Lenovo laptops with a USB4 dock.

Since commit 0fc70886569c ("thunderbolt: Reset USB4 v2 host router") and
commit 59a54c5f3dbd ("thunderbolt: Reset topology created by the boot
firmware"), USB4 v2 and v1 Host Routers are reset on probe of the
thunderbolt driver.

The reset clears the Presence Detect State and Data Link Layer Link Active
bits at the USB4 Host Router's Root Port and thus causes hot removal of the
dock.

The crash occurs when pciehp is unbound from one of the dock's Downstream
Ports:  pciehp creates a pci_slot on bind and destroys it on unbind.  The
pci_slot contains a pointer to the pci_bus below the Downstream Port, but
a reference on that pci_bus is never acquired.  The pci_bus is destroyed
before the pci_slot, so a use-after-free ensues when pci_slot_release()
accesses slot->bus.

In principle this should not happen because pci_stop_bus_device() unbinds
pciehp (and therefore destroys the pci_slot) before the pci_bus is
destroyed by pci_remove_bus_device().

However the stacktrace provided by Dennis shows that pciehp is unbound from
pci_remove_bus_device() instead of pci_stop_bus_device().  To understand
the significance of this, one needs to know that the PCI core uses a two
step process to remove a portion of the hierarchy:  It first unbinds all
drivers in the sub-hierarchy in pci_stop_bus_device() and then actually
removes the devices in pci_remove_bus_device().  There is no precaution to
prevent driver binding in-between pci_stop_bus_device() and
pci_remove_bus_device().

In Dennis' case, it seems removal of the hierarchy by pciehp races with
driver binding by pci_bus_add_devices().  pciehp is bound to the
Downstream Port after pci_stop_bus_device() has run, so it is unbound by
pci_remove_bus_device() instead of pci_stop_bus_device().  Because the
pci_bus has already been destroyed at that point, accesses to it result in
a use-after-free.

One might conclude that driver binding needs to be prevented after
pci_stop_bus_device() has run.  However it seems risky that pci_slot points
to pci_bus without holding a reference.  Solely relying on correct ordering
of driver unbind versus pci_bus destruction is certainly not defensive
programming.

If pci_slot has a need to access data in pci_bus, it ought to acquire a
reference.  Amend pci_create_slot() accordingly.  Dennis reports that the
crash is not reproducible with this change.

Subject: [PATCH 1249/2948] perf arm-spe: Use old behavior when opening old SPE
 files

Since the linked commit, we stopped interpreting data source if the
perf.data file doesn't have the new metadata version. This means that
perf c2c will show no samples in this case.

Keep the old behavior so old files can be opened, but also still show
the new warning that updating might improve the decoding.

Also re-write the warning to be more concise and specific to a user.

Subject: [PATCH 1255/2948] iio: accel: kx022a: Fix raw read format

The KX022A provides the accelerometer data in two subsequent registers.
The registers are laid out so that the value obtained via bulk-read of
these registers can be interpreted as signed 16-bit little endian value.
The read value is converted to cpu_endianes and stored into 32bit integer.
The le16_to_cpu() casts value to unsigned 16-bit value, and when this is
assigned to 32-bit integer the resulting value will always be positive.

This has not been a problem to users (at least not all users) of the sysfs
interface, who know the data format based on the scan info and who have
converted the read value back to 16-bit signed value. This isn't
compliant with the ABI however.

This, however, will be a problem for those who use the in-kernel
interfaces, especially the iio_read_channel_processed_scale().

The iio_read_channel_processed_scale() performs multiplications to the
returned (always positive) raw value, which will cause strange results
when the data from the sensor has been negative.

Fix the read_raw format by casting the result of the le_to_cpu() to
signed 16-bit value before assigning it to the integer. This will make
the negative readings to be correctly reported as negative.

This fix will be visible to users by changing values returned via sysfs
to appear in correct (negative) format.

specific address. This is generally set by the 'assigned-address' in the
device tree source (dts) file.

 ┌────┬─────────────┬───┬─────────┬───┐
 │S/Sr│ 7'h7E RnW=0 │ACK│ ENTDAA  │ T ├────┐
 └────┴─────────────┴───┴─────────┴───┘    │

    └──┴─────────────┴───┴─────────────────┴────────────────┴───┴─────────┘

Some master controllers (such as HCI) need to prepare the entire above
transaction before sending it out to the I3C bus. This means that a 7-bit
dynamic address needs to be allocated before knowing the target device's
UID information.

However, some I3C targets may request specific addresses (called as
"init_dyn_addr"), which is typically specified by the DT-'s
assigned-address property. Lower addresses having higher IBI priority. If
it is available, i3c_bus_get_free_addr() preferably return a free address
that is not in the list of desired addresses (called as "init_dyn_addr").
This allows the device with the "init_dyn_addr" to switch to its
"init_dyn_addr" when it hot-joins the I3C bus. Otherwise, if the
"init_dyn_addr" is already in use by another I3C device, the target device
will not be able to switch to its desired address.

If the previous step fails, fallback returning one of the remaining
unassigned address, regardless of its state in the desired list.

Subject: [PATCH 1258/2948] i3c: master: Fix dynamic address leak when
 'assigned-address' is present

If the DTS contains 'assigned-address', a dynamic address leak occurs
during hotjoin events.

Assume a device have assigned-address 0xb.
  - Device issue Hotjoin
  - Call i3c_master_do_daa()
  - Call driver xxx_do_daa()
  - Call i3c_master_get_free_addr() to get dynamic address 0x9
  - i3c_master_add_i3c_dev_locked(0x9)
  -     expected_dyn_addr  = newdev->boardinfo->init_dyn_addr (0xb);
  -     i3c_master_reattach_i3c_dev(newdev(0xb), old_dyn_addr(0x9));
  -         if (dev->info.dyn_addr != old_dyn_addr &&
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 0xb != 0x9 -> TRUE
                (!dev->boardinfo ||
                 ^^^^^^^^^^^^^^^ ->  FALSE
                 dev->info.dyn_addr != dev->boardinfo->init_dyn_addr)) {
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                 0xb != 0xb      ->  FALSE
                 ...
                 i3c_bus_set_addr_slot_status(&master->bus, old_dyn_addr,
                                                     I3C_ADDR_SLOT_FREE);
		 ^^^
                 This will be skipped. So old_dyn_addr never free
            }

  - i3c_master_get_free_addr() will return increased sequence number.

Remove dev->info.dyn_addr != dev->boardinfo->init_dyn_addr condition check.
dev->info.dyn_addr should be checked before calling this function because
i3c_master_setnewda_locked() has already been called and the target device
has already accepted dyn_addr. It is too late to check if dyn_addr is free
in i3c_master_reattach_i3c_dev().

Add check to ensure expected_dyn_addr is free before
i3c_master_setnewda_locked().

Subject: [PATCH 1259/2948] i3c: master: svc: use repeat start when IBI WIN
 happens

There is a possibility of an IBI WIN occurring when addressing issues, even
when sending CCC commands. Most of the time, returning -EAGAIN is
acceptable, but the case below becomes highly complex.

When a Hotjoin event occurs:
- i3c_master_do_daa()
  - i3c_master_add_i3c_dev_locked()
    - A dynamic address (e.g., 0x9) is already set during DAA.
    - i3c_master_getpid_locked()
      - Another device issues HJ or IBI here. Returning -EAGAIN causes
        failure in adding the new device. However, the dynamic address(0x9)
        has already been assigned to this device. If another device issues
        HJ, it will get this address 0x9 again, causing two devices on the
        bus to use the same dynamic address 0x9.
      - Attempting to send RSTDAA when the first device fails at
        i3c_master_getpid_locked() could also fail when sending RSTDAA for
        the same reason.

According to the I3C spec, address arbitration only happens at START, never
at REPEAT start. Using repeat start when an IBI WIN occurs simplifies this
case, as i3c_master_getpid_locked() will not return an error when another
device tries to send HJ or IBI.

When the address is arbitrated at send address, the hardware can auto-send
NACK if it is an IBI. However, manual emission of NACK/ACK is needed for
hot join or controller request events.

Add help function svc_i3c_master_handle_ibi_won() to check event type and
send out NACK if the event is not an IBI.

Subject: [PATCH 1262/2948] i3c: master: svc: use spin_lock_irqsave at
 svc_i3c_master_ibi_work()

According to I3C spec ver 1.1, 09-Jun-2021, section 5.1.2.5:

The I3C Controller shall hold SCL low while the Bus is in ACK/NACK Phase of
I3C/I2C transfer. But maximum stall time is 100us. The IRQs have to be
disabled to prevent schedule during the whole I3C transaction, otherwise,
the I3C bus timeout may happen if any irq or schedule happen during
transaction.

Replace mutex with spin_lock_irqsave() to avoid stalling SCL more than
100us.

            goto rpm_out;
    }
}

If two devices (A and B) are detected in DAA and address 0xa is assigned to
device A and 0xb to device B, a failure in i3c_master_add_i3c_dev_locked()
for device A (addr: 0xa) could prevent device B (addr: 0xb) from being
registered on the bus. The I3C stack might still consider 0xb a free
address. If a subsequent Hotjoin occurs, 0xb might be assigned to Device A,
causing both devices A and B to use the same address 0xb, violating the I3C
specification.

The return value for i3c_master_add_i3c_dev_locked() should not be checked
because subsequent steps will scan the entire I3C bus, independent of
whether i3c_master_add_i3c_dev_locked() returns success.

If device A registration fails, there is still a chance to register device
B. i3c_master_add_i3c_dev_locked() can reset DAA if a failure occurs while
retrieving device information.

Subject: [PATCH 1265/2948] i3c: master: Remove
 i3c_dev_disable_ibi_locked(olddev) on device hotjoin

When a new device hotjoins, a new dynamic address is assigned.
i3c_master_add_i3c_dev_locked() identifies that the device was previously
attached to the bus and locates the olddev.

i3c_master_add_i3c_dev_locked()
{
    ...
    olddev = i3c_master_search_i3c_dev_duplicate(newdev);
    ...
    if (olddev) {
        ...
        i3c_dev_disable_ibi_locked(olddev);
        ^^^^^^
        The olddev should not receive any commands on the i3c bus as it
        does not exist and has been assigned a new address. This will
        result in NACK or timeout. So remove it.
    }

    i3c_dev_free_ibi_locked(olddev);
    ^^^^^^^^
    This function internally calls i3c_dev_disable_ibi_locked() function
    causing to send DISEC command with old Address.

    The olddev should not receive any commands on the i3c bus as it
    does not exist and has been assigned a new address. This will
    result in NACK or timeout. So, update the olddev->ibi->enabled
    flag to false to avoid DISEC with OldAddr.

 stop request

Bus cleanup path in DMA mode may trigger a RING_OP_STAT interrupt when
the ring is being stopped. Depending on timing between ring stop request
completion, interrupt handler removal and code execution this may lead
to a NULL pointer dereference in hci_dma_irq_handler() if it gets to run
after the io_data pointer is set to NULL in hci_dma_cleanup().

Prevent this my masking the ring interrupts before ring stop request.

Subject: [PATCH 1268/2948] i3c: mipi-i3c-hci: Handle interrupts according to
 current specifications

Current MIPI I3C HCI specification versions pre-1.0, 1.0. 1.1 and 1.2
don't have cascaded interrupt bits for the PIO and DMA (ring headers) in
the INTR_STATUS register as implemented currently in the code. Instead
bits 9:0 are marked as reserved with unspecified reset value.

To my understanding they were planned to be introduced in the version 2
and the original commit 9ad9a52cce28 ("i3c/master: introduce the
mipi-i3c-hci driver") was coding ahead according to a draft. With
remarks though.

This is causing that the DMA handler is not called until at least one
reserved bit 7:0 is set in the INTR_STATUS.

Since it looks that idea was dropped in later official versions and to
make able to handle DMA interrupts on an HW that is implemented
according to current specifications call assigned PIO or DMA IO handler
unconditionally.

While doing so remove cascaded interrupt bit definitions and the mask
argument passed to the handler functions.

Subject: [PATCH 1269/2948] i3c: master: svc: Fix pm_runtime_set_suspended()
 with runtime pm enabled

It is not valid to call pm_runtime_set_suspended() for devices
with runtime PM enabled because it returns -EAGAIN if it is enabled
already and working. So, call pm_runtime_disable() before to fix it.

Subject: [PATCH 1270/2948] dt-bindings: rtc: renesas,rzg3s-rtc: Document the
 Renesas RTCA-3 IP

Document the RTC IP (RTCA-3) available on the Renesas RZ/G3S SoC.
The RTC IP available on Renesas RZ/V2H is almost identical with the
one found on Renesas RZ/G3S (it misses the time capture functionality
which is not yet implemented on proposed driver). For this, added also a
generic compatible that will be used at the moment as fallback for both
RZ/G3S and RZ/V2H.

Subject: [PATCH 1271/2948] rtc: renesas-rtca3: Add driver for RTCA-3 available
 on Renesas RZ/G3S SoC

The RTC IP (RTCA-3) available on the Renesas RZ/G3S SoC has calendar count
mode and binary count mode (selectable though RCR2.CNTMD) capabilities,
alarm capabilities, clock error correction capabilities. It can generate
alarm, period, carry interrupts.

Add a driver for RTCA-3 IP. The driver implements calendar count mode (as
the conversion b/w RTC and system time is simpler, done with bcd2bin(),
bin2bcd()), read and set time, read and set alarm, read and set
an offset.

Subject: [PATCH 1272/2948] rtc: cmos: avoid taking rtc_lock for extended
 period of time
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On my device reading entirety of /sys/devices/pnp0/00:03/cmos_nvram0/nvmem
takes about 9 msec during which time interrupts are off on the CPU that
does the read and the thread that performs the read can not be migrated
or preempted by another higher priority thread (RT or not).

Allow readers and writers be preempted by taking and releasing rtc_lock
spinlock for each individual byte read or written rather than once per
read/write request.

RIP: 0010:f2fs_invalidate_blocks+0x35f/0x370 fs/f2fs/segment.c:2534

The root cause is: on a fuzzed image, blkaddr in nat entry may be
corrupted, then it will cause system panic when using it in
f2fs_invalidate_blocks(), to avoid this, let's add sanity check on
nat blkaddr in truncate_node().

  #1             1        0        0     8191        0

mkfs.f2fs -f -s 2 -c /dev/vdc /dev/vdb
mount /dev/vdb /mnt/f2fs
cat /sys/kernel/debug/f2fs/status

Multidevice stats:

Subject: [PATCH 1276/2948] f2fs: introduce device aliasing file

F2FS should understand how the device aliasing file works and support
deleting the file after use. A device aliasing file can be created by
mkfs.f2fs tool and it can map the whole device with an extent, not
using node blocks. The file space should be pinned and normally used for
read-only usages.

+Device aliasing feature
+-----------------------
+
+f2fs can utilize a special file called a "device aliasing file." This file allows
+the entire storage device to be mapped with a single, large extent, not using
+the usual f2fs node structures. This mapped area is pinned and primarily intended
+for holding the space.
+
+Essentially, this mechanism allows a portion of the f2fs area to be temporarily
+reserved and used by another filesystem or for different purposes. Once that
+external usage is complete, the device aliasing file can be deleted, releasing
+the reserved space back to F2FS for its own use.
+
+<use-case>
+
+# ls /dev/vd*
+/dev/vdb (32GB) /dev/vdc (32GB)
+# mkfs.ext4 /dev/vdc
+# mkfs.f2fs -c /dev/vdc@vdc.file /dev/vdb
+# mount /dev/vdb /mnt/f2fs
+# ls -l /mnt/f2fs
+vdc.file
+# df -h
+/dev/vdb                            64G   33G   32G  52% /mnt/f2fs
+
+# mount -o loop /dev/vdc /mnt/ext4
+# df -h
+/dev/vdb                            64G   33G   32G  52% /mnt/f2fs
+/dev/loop7                          32G   24K   30G   1% /mnt/ext4
+# umount /mnt/ext4
+
+# f2fs_io getflags /mnt/f2fs/vdc.file
+get a flag on /mnt/f2fs/vdc.file ret=0, flags=nocow(pinned),immutable
+# f2fs_io setflags noimmutable /mnt/f2fs/vdc.file
+get a flag on noimmutable ret=0, flags=800010
+set a flag on /mnt/f2fs/vdc.file ret=0, flags=noimmutable
+# rm /mnt/f2fs/vdc.file
+# df -h
+/dev/vdb                            64G  753M   64G   2% /mnt/f2fs
+
+So, the key idea is, user can do any file operations on /dev/vdc, and
+reclaim the space after the use, while the space is counted as /data.
+That doesn't require modifying partition size and filesystem format.

Subject: [PATCH 1277/2948] f2fs: zone: introduce first_zoned_segno in
 f2fs_sb_info

first_zoned_segno() returns a fixed value, let's cache it in
structure f2fs_sb_info to avoid redundant calculation.

Subject: [PATCH 1278/2948] f2fs: fix the wrong f2fs_bug_on condition in
 f2fs_do_replace_block

This f2fs_bug_on was introduced by commit 2c1905042c8c ("f2fs: check
segment type in __f2fs_replace_block") when there were only 6 curseg types.
After commit d0b9e42ab615 ("f2fs: introduce inmem curseg") was introduced,
the condition should be changed to checking curseg->seg_type.

Subject: [PATCH 1280/2948] f2fs: modify f2fs_is_checkpoint_ready logic to
 allow more data to be written with the CP disable

When the free segment is used up during CP disable, many write or
ioctl operations will get ENOSPC error codes, even if there are
still many blocks available. We can reproduce it in the following
steps:

dd if=/dev/zero of=f2fs.img bs=1M count=65
mkfs.f2fs -f f2fs.img
mount f2fs.img f2fs_dir -o checkpoint=disable:10%
cd f2fs_dir
i=1 ; while [[ $i -lt 50 ]] ; do (file_name=./2M_file$i ; dd \
if=/dev/random of=$file_name bs=1M count=2); i=$((i+1)); done
sync
i=1 ; while [[ $i -lt 50 ]] ; do (file_name=./2M_file$i ; truncate \
-s 1K $file_name); i=$((i+1)); done
sync
dd if=/dev/zero of=./file bs=1M count=20

In f2fs_need_SSR() function, it is allowed to use SSR to allocate
blocks when CP is disabled, so in f2fs_is_checkpoint_ready function,
can we judge the number of invalid blocks when free segment is not
enough, and return ENOSPC only if the number of invalid blocks is
also not enough.

other info that might help us debug this:

Chain exists of:
  &sbi->sb_lock --> fs_reclaim --> sb_internal#2

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  rlock(sb_internal#2);
                               lock(fs_reclaim);
                               lock(sb_internal#2);
  lock(&sbi->sb_lock);

Root cause is there will be potential deadlock in between
below tasks:

Thread A				Kswapd
- f2fs_ioc_commit_atomic_write
 - mnt_want_write_file -- down_read lock A
					- balance_pgdat
					 - __fs_reclaim_acquire  -- lock B
					  - shrink_node
					   - prune_icache_sb
					    - dispose_list
					     - f2fs_evict_inode
					      - sb_start_intwrite  -- down_read lock A
 - f2fs_do_sync_file
  - f2fs_write_inode
   - f2fs_handle_critical_error
    - f2fs_record_stop_reason
     - f2fs_commit_super
      - read_mapping_folio
       - filemap_alloc_folio_noprof
        - fs_reclaim_acquire  -- lock B

Both threads try to acquire read lock of lock A, then its upcoming write
lock grabber will trigger deadlock.

Let's always create an asynchronous task in f2fs_handle_critical_error()
rather than calling f2fs_record_stop_reason() synchronously to avoid
this potential deadlock issue.

In __get_segment_type(), __get_segment_type_6() may return
CURSEG_COLD_DATA_PINNED or CURSEG_ALL_DATA_ATGC log type, but
following f2fs_get_segment_temp() can only handle persistent
log type, fix it.

Subject: [PATCH 1285/2948] f2fs: fix to avoid use GC_AT when setting gc_mode
 as GC_URGENT_LOW or GC_URGENT_MID

If gc_mode is set to GC_URGENT_LOW or GC_URGENT_MID, cost benefit GC
approach should be used, but if ATGC is enabled at the same time,
Age-threshold approach will be selected, which can only do amount of
GC and it is much less than the numbers of CB approach.

Subject: [PATCH 1288/2948] f2fs: fix to convert log type to segment data type
 correctly

This patch introduces a new helper log_type_to_seg_type() to convert
log type to segment data type, and uses it to clean up opened codes
in build_curseg(), and also it fixes to convert log type before use
in do_write_page().

Subject: [PATCH 1290/2948] counter: stm32-timer-cnt: fix device_node handling
 in probe_encoder()

Device nodes accessed via of_get_compatible_child() require
of_node_put() to be called when the node is no longer required to avoid
leaving a reference to the node behind, leaking the resource.

In this case, the usage of 'tnode' is straightforward and there are no
error paths, allowing for a single of_node_put() when 'tnode' is no
longer required.

Use or pass ARRAY_SIZE() of the capabilities array instead of hardcoding

that distinguish between the Gen 2/3 and Gen 4 margins since they behave
differently between generations.

Subject: [PATCH 1293/2948] thunderbolt: debugfs: Implement Gen 4 margining eye
 selection

Add a debugfs knob for USB4 Gen 4 margining eye selection. Gen 4 uses
3-level pulse amplitude modulation (PAM3) which changes how margining
measurements are made because PAM3 has two eyes per lane from which
the margins can be measured.

Subject: [PATCH 1294/2948] thunderbolt: debugfs: Replace "both lanes" with
 "all lanes"

With USB4 Gen 4, the link can be configured into an asymmetric mode,
where there are three receivers and only one transmitter. The USB4
specification also uses the "all lanes" nomenclature instead of "both
lanes".

Subject: [PATCH 1299/2948] counter: intel-qep: Replace deprecated PCI
 functions

pcim_iomap_regions() and pcim_iomap_table() have been deprecated in
commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(),
pcim_iomap_regions_request_all()").

Replace these functions with pcim_iomap_region().

Subject: [PATCH 1308/2948] iio: accel: kxcjk-1013: drop ACPI_PTR() and move ID
 out of CONFIG_ACPI guards

The complexity of config guards needed for ACPI_PTR() is not worthwhile
for the small amount of saved data. This example was doing it correctly
but I am proposing dropping this so as to reduce chance of cut and paste
where it is done wrong. Also added linux/mod_devicetable.h for
struct acpi_device_id definition.

Subject: [PATCH 1313/2948] iio: light: isl29018: drop ACPI_PTR() and
 CONFIG_ACPI guards

The complexity of config guards needed for ACPI_PTR() is not worthwhile
for the small amount of saved data. This example was doing it correctly
but I am proposing dropping this so as to reduce chance of cut and paste
where it is done wrong.  Also drop now unneeded linux/acpi.h include and
added linux/mod_devicetable.h for struct acpi_device_id definition.

Subject: [PATCH 1314/2948] iio: light: ltr501: Drop most likely fake ACPI IDs

The commits in question do not proove that ACPI IDs exist.
Quite likely it was a cargo cult addition while doing that
for DT-based enumeration. Drop most likely fake ACPI IDs.

The to be removed IDs has been checked against the following resources:
1) DuckDuckGo
2) Google
3) MS catalog: https://www.catalog.update.microsoft.com/Search.aspx
This gives no useful results in regard to DSDT, moreover, the official
vendor ID in the registry for Lite-On is LCI.

Subject: [PATCH 1324/2948] iio: dac: ad5380: drop driver remove callbacks

Drop use of the driver remove callbacks in the ad5380 driver.

By making use of a few more devm_ helpers, we can avoid the need for
remove callbacks entirely.

Also make use of dev_err_probe() while at it.

The veml3235 is another Vishay ambient light sensor that shares similar
properties with the other sensors covered by this bindings. In this
case, only the compatible, reg, and vdd-supply properties are required,
and the device does not have an interrupt line, like the already
supported veml7700.

The Vishay veml3235 is a low-power ambient light sensor with I2C
interface. It provides a minimum detectable intensity of
0.0021 lx/cnt, configurable integration time and gain, and an additional
white channel to distinguish between different light sources.

Subject: [PATCH 1341/2948] iio: chemical: bme680: generalize read_*()
 functions

Remove the IIO specific scaling measurement units from the read functions
and add them inside the ->read_raw() function to keep the read_*() generic.
This way they can be used in other parts of the driver.

Subject: [PATCH 1345/2948] iio: imu: bmi270: Add support for BMI260

Adds support for the Bosch BMI260 6-axis IMU to the Bosch BMI270
driver. Setup and operation is nearly identical to the Bosch BMI270,
but has a different chip ID and requires different firmware.

Firmware is requested and loaded from userspace.

Adds ACPI ID BMI0160, used by several devices including the GPD Win
Mini, Aya Neo AIR Pro, and OXP Mini Pro.

GPD Win Mini:

Device (BMI2)
{
    Name (_ADR, Zero)  // _ADR: Address
    Name (_HID, "BMI0160")  // _HID: Hardware ID
    Name (_CID, "BMI0160")  // _CID: Compatible ID
    Name (_DDN, "Accelerometer")  // _DDN: DOS Device Name
    Name (_UID, One)  // _UID: Unique ID
    Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings
    {
        Name (RBUF, ResourceTemplate ()
        {
            I2cSerialBusV2 (0x0068, ControllerInitiated, 0x00061A80,
                AddressingMode7Bit, "\\_SB.I2CB",
                0x00, ResourceConsumer, , Exclusive,
                )
            GpioInt (Edge, ActiveLow, Exclusive, PullDefault, 0x0000,
                "\\_SB.GPIO", 0x00, ResourceConsumer, ,
                )
                {   // Pin list
                    0x008B
                }
        })
        Return (RBUF) /* \_SB_.I2CB.BMI2._CRS.RBUF */
    }

possible endianness and initialization issues are avoided.

 support

There is a version of AXI DAC IP block (for FPGAs) that provides
a physical QSPI bus for AD3552R and similar chips, so supporting
spi-controller functionalities.

For this case, the binding is modified to include some additional
properties.

Subject: [PATCH 1350/2948] dt-bindings: iio: dac: adi-axi-dac: add ad3552r axi
 variant

Add a new compatible and related bindigns for the fpga-based
"ad3552r" AXI IP core, a variant of the generic AXI DAC IP.

The AXI "ad3552r" IP is a very similar HDL (fpga) variant of the
generic AXI "DAC" IP, intended to control ad3552r and similar chips,
mainly to reach high speed transfer rates using a QSPI DDR
(dobule-data-rate) interface.

The ad3552r device is defined as a child of the AXI DAC, that in
this case is acting as an SPI controller.

Note, #io-backend is present because it is possible (in theory anyway)
to use a separate controller for the control path than that used
for the datapath.

Subject: [PATCH 1352/2948] iio: dac: adi-axi-dac: extend features

Extend AXI-DAC backend with new features required to interface
to the ad3552r DAC. Mainly, a new compatible string is added to
support the ad3552r-axi DAC IP, very similar to the generic DAC
IP but with some customizations to work with the ad3552r.

Then, a series of generic functions has been added to match with
ad3552r needs. Function names has been kept generic as much as
possible, to allow re-utilization from other frontend drivers.

The adxl380_read_chn function returns either a negative value in case an
error occurs or the actual sample.

Check only for negative values after a channel is read.

Subject: [PATCH 1356/2948] rust: kbuild: expand rusttest target for macros

Previously, the rusttest target for the macros crate did not specify
the dependencies necessary to run the rustdoc tests. These tests rely on
the kernel crate, so add the dependencies.

[ Rebased (`alloc` is gone nowadays, sysroot handling is simpler) and
  simplified (reused `rustdoc_test` rule instead of adding a new one,
  no need for `rustdoc-compiler_builtins`, removed unneeded `macros`
  explicit path). Made `vtable` example fail (avoiding to increase
  the complexity in the `rusttest` target). Removed unstable
  `-Zproc-macro-backtrace` option. Reworded accordingly. - Miguel ]

Previously, these tests were ignored due to a missing necessary dependency
on the `kernel` crate. Enable the tests, and update them: for both,
add the parameter to `init()`; for the first one, remove the use of a
kernel parameter mechanism that was never merged.

Subject: [PATCH 1358/2948] rust: macros: enable paste! use from macro_rules!

According to the rustdoc for the proc_macro crate[1], tokens captured
from a "macro variable" (e.g. from within macro_rules!) may be delimited
by invisible tokens and be contained within a proc_macro::Group.

Previously, this scenario was not handled by macros::paste, which caused
a proc-macro panic when the corresponding tests are enabled. Enable the
tests, and handle this case by making macros::paste::concat recursive.

Subject: [PATCH 1360/2948] perf stat: Support inherit events during fork() for
 bperf

bperf has a nice ability to share PMUs, but it still does not support
inherit events during fork(), resulting in some deviations in its stat
results compared with perf.

perf stat result:
$ ./perf stat -e cycles,instructions -- ./perf test -w sqrtloop
   Performance counter stats for './perf test -w sqrtloop':

       2,316,038,116      cycles
       2,859,350,725      instructions

         1.009603637 seconds time elapsed

         1.004196000 seconds user
         0.003950000 seconds sys

bperf stat result:
$ ./perf stat --bpf-counters -e cycles,instructions -- \
      ./perf test -w sqrtloop

   Performance counter stats for './perf test -w sqrtloop':

          18,762,093      cycles
          23,487,766      instructions

         1.008913769 seconds time elapsed

         1.003248000 seconds user
         0.004069000 seconds sys

In order to support event inheritance, two new bpf programs are added
to monitor the fork and exit of tasks respectively. When a task is
created, add it to the filter map to enable counting, and reuse the
`accum_key` of its parent task to count together with the parent task.
When a task exits, remove it from the filter map to disable counting.

After support:
$ ./perf stat --bpf-counters -e cycles,instructions -- \
      ./perf test -w sqrtloop

 Performance counter stats for './perf test -w sqrtloop':

     2,316,252,189      cycles
     2,859,946,547      instructions

Subject: [PATCH 1365/2948] PCI: qcom: Enable MSI interrupts together with Link
 up if 'Global IRQ' is supported
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, if 'Global IRQ' is supported by the platform, only the Link up
interrupt is enabled in the PARF_INT_ALL_MASK register. This masks MSIs
on some platforms. The MSI bits in PARF_INT_ALL_MASK register are enabled
by default in the hardware, but commit 4581403f6792 ("PCI: qcom: Enumerate
endpoints based on Link up event in 'global_irq' interrupt") disabled them
and enabled only the Link up interrupt. While MSI continued to work on the
SM8450 platform that was used to test the offending commit, on other
platforms like SM8250, X1E80100, MSIs are getting masked. And they require
enabling the MSI interrupt bits in the register to unmask (enable) the
MSIs.

Even though the MSI interrupt enable bits in PARF_INT_ALL_MASK are
described as 'diagnostic' interrupts in the internal documentation,
disabling them masks MSI on these platforms. Due to this, MSIs were not
reported to be received these platforms while supporting 'Global IRQ'.

So, enable the MSI interrupts along with the Link up interrupt in the
PARF_INT_ALL_MASK register if 'Global IRQ' is supported. This ensures that
the MSIs continue to work and also the driver is able to catch the Link
up interrupt for enumerating endpoint devices.

Fixes: 4581403f6792 ("PCI: qcom: Enumerate endpoints based on Link up event in 'global_irq' interrupt")

The output of ".%03u" with the unsigned int in range [0, 4294966295] may
get truncated if the target buffer is not 12 bytes. This can't really
happen here as the 'remainder' variable cannot exceed 999 but the
compiler doesn't know it. To make it happy just increase the buffer to
where the warning goes away.

Subject: [PATCH 1371/2948] scsi: ufs: exynos: Allow UFS Gear 4

UFS Gear 4 offers faster speeds, and better power usage so lets enable
it.

Currently ufshcd_init_host_params() sets UFS_HS_G3 as a default, so even
if the device supports G4 we end up negotiating down to G3.

For SoCs like gs101 which have a UFS major controller version of 3 or
above advertise Gear 4. This then allows a Gear 4 link on Pixel 6.

For earlier controller versions keep the current default behaviour of
reporting G3.

Move the EXYNOS_UFS_OPT_UFSPR_SECURE check inside

This way all call sites will benefit from the check. This fixes a bug
currently in the exynos_ufs_resume() path on gs101 as it calls
exynos_ufs_config_smu() and we end up accessing registers that can only
be accessed from secure world which results in a serror.

Subject: [PATCH 1377/2948] scsi: ufs: exynos: Add gs101_ufs_drv_init() hook
 and enable WriteBooster

Factor out the common code into a new exynos_ufs_shareability() function
and provide a dedicated gs101_drv_init() hook.

This allows us to enable WriteBooster capability (UFSHCD_CAP_WB_EN) in a
way that doesn't effect other SoCs supported in this driver.

WriteBooster improves write speeds by enabling a pseudo SLC cache. Using
the 'fio seqwrite' test we can achieve speeds of 945MB/s with this
feature enabled (until the cache is exhausted) before dropping back to
~260MB/s (which are the speeds we see without the WriteBooster feature
enabled).

Assuming the UFSHCD_CAP_WB_EN capability is set by the host then
WriteBooster can also be enabled and disabled via sysfs so it is
possible for the system to only enable it when extra write performance
is required.

Subject: [PATCH 1378/2948] scsi: ufs: exynos: Enable write line unique
 transactions on gs101

Currently just AXIDMA_RWDATA_BURST_LEN[3:0] field is set to 8 in
exynos_ufs_post_link() function.

To enable WLU transaction additionally we need to set Write Line Unique
enable [31], Write Line Unique Burst Length [30:27] and
AXIDMA_RWDATA_BURST_LEN[3:0].

To support WLU transaction on gs101, both burst length fields need to be
0x3. As all other SoCs expect the current value we update this in the
gs101_ufs_post_link() specific hook.

Subject: [PATCH 1379/2948] scsi: ufs: exynos: Set ACG to be controlled by
 UFS_ACG_DISABLE

HCI_IOP_ACG_DISABLE is an undocumented register in the TRM but the
downstream driver sets this register so we follow suit here.

The register is already 0 presumed to be set by the bootloader as the
comment downstream implies the reset state is 1. So whilst this is a nop
currently, it should protect us in case the bootloader behaviour ever
changes.

Subject: [PATCH 1380/2948] scsi: ufs: exynos: Fix hibern8 notify callbacks

v1 of the patch which introduced the ufshcd_vops_hibern8_notify()
callback used a bool instead of an enum. In v2 this was updated to an
enum based on the review feedback in [1].

ufs-exynos hibernate calls have always been broken upstream as it
follows the v1 bool implementation.

Subject: [PATCH 1381/2948] scsi: ufs: exynos: gs101: Enable clock gating with
 hibern8

Enable clock gating and hibern8 capabilities for gs101. This leads to a
significantly cooler phone when running the upstream kernel.

The exynos_ufs_post_hibern8() hook is also updated to remove the
UIC_CMD_DME_HIBER_EXIT code path as this causes a hang on gs101.

The code path is removed rather than re-factored as no other SoC in
ufs-exynos driver sets UFSHCD_CAP_HIBERN8_WITH_CLK_GATING
capability. Additionally until the previous commit the hibern8 callbacks
were broken anyway as they expected a bool.

Should an rport remain in the NOTPRESENT state it is possible that
stgt_delete_work is scheduled after dev_loss_tmo_callbk.  In such cases,
dev_loss_tmo_callbk would have cleaned up the NDLP object resulting in
stale ndlp pointers in lpfc_terminate_rport_io().

Check for the DEVLOSS_CALLBK_DONE flag to know if dev_loss_tmo_callbk
has been called.  This is a more reliable way to avoid dereferencing
stale NDLP pointers.

Subject: [PATCH 1384/2948] scsi: lpfc: Call lpfc_sli4_queue_unset() in restart
 and rmmod paths

During initialization, the driver allocates wq->pring in lpfc_wq_create
and lpfc_sli4_queue_unset() is the only place where kfree(wq->pring) is
called.

There is a possible memory leak in lpfc_sli_brdrestart_s4() (restart)
and lpfc_pci_remove_one_s4() (rmmod) paths because there are no calls to
lpfc_sli4_queue_unset() to kfree() the wq->pring.

Fix by inserting a call to lpfc_sli4_queue_unset() in
lpfc_sli_brdrestart_s4() and lpfc_sli4_hba_unset() routines.  Also, add
a check for the SLI_ACTIVE flag before issuing the Q_DESTROY mailbox
command.  If not set, then the mailbox command will obviously fail.  In
such cases, skip issuing the mailbox command and only execute the driver
resource clean up portions of the lpfc_*q_destroy routines.

Subject: [PATCH 1385/2948] scsi: lpfc: Update lpfc_els_flush_cmd() to check
 for SLI_ACTIVE before BSG flag

During firmware errata events, the lpfc_els_flush_cmd() routine is
responsible for the clean up of outstanding ELS and CT command
submissions.  Thus, move the LPFC_SLI_ACTIVE flag check into the txcmplq
list walk and mark a piocb object for canceling if determined the HBA is
not active.  Clean up should be regardless of application or driver
layer origin.

Subject: [PATCH 1386/2948] scsi: lpfc: Check SLI_ACTIVE flag in FDMI cmpl
 before submitting follow up FDMI

The lpfc_cmpl_ct_disc_fdmi() routine has incorrect logic that treats an
FDMI completion with error LOCAL_REJECT/SLI_ABORTED as a success status.
Under the erroneous assumption of successful completion, the routine
proceeds to issue follow up FDMI commands, which may never complete if
the HBA is in an errata state as indicated by the errored completion
status.  Fix by freeing FDMI cmd resources and early return when the
LPFC_SLI_ACTIVE flag is not set and a LOCAL_REJECT/SLI_ABORTED or
SLI_DOWN status is received.

Subject: [PATCH 1387/2948] scsi: lpfc: Add cleanup of nvmels_wq after HBA
 reset

An HBA reset request that is executed when there are outstanding NVME-LS
commands can cause delays for the reset process to complete.  Fix by
introducing a new routine called lpfc_nvmels_flush_cmd() that walks the
phba->nvmels_wq list and cancels outstanding submitted NVME-LS requests
speeding up the HBA reset process.

Subject: [PATCH 1388/2948] scsi: lpfc: Prevent NDLP reference count underflow
 in dev_loss_tmo callback

Current dev_loss_tmo handling checks whether there has been a previous
call to unregister with SCSI transport.  If so, the NDLP kref count is
decremented a second time in dev_loss_tmo as the final kref release.
However, this can sometimes result in a reference count underflow if
there is also a race to unregister with NVMe transport as well.  Add a
check for NVMe transport registration before decrementing the final
kref.  If NVMe transport is still registered, then the NVMe transport
unregistration is designated as the final kref decrement.

From: Justin Tee <justin.tee@broadcom.com>
Date: Thu, 31 Oct 2024 15:32:17 -0700
Subject: [PATCH 1390/2948] scsi: lpfc: Change lpfc_nodelist nlp_flag member
 into a bitmask

In attempt to reduce the amount of unnecessary ndlp->lock acquisitions
in the lpfc driver, change nlpa_flag into an unsigned long bitmask and
use clear_bit/test_bit bitwise atomic APIs instead of reliance on
ndlp->lock for synchronization.

Subject: [PATCH 1393/2948] PCI: qcom-ep: Move controller cleanups to
 qcom_pcie_perst_deassert()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, the endpoint cleanup function dw_pcie_ep_cleanup() and EPF
deinit notify function pci_epc_deinit_notify() are called during the
execution of qcom_pcie_perst_assert() i.e., when the host has asserted
PERST#. But quickly after this step, refclk will also be disabled by the
host.

All of the Qcom endpoint SoCs supported as of now depend on the refclk from
the host for keeping the controller operational. Due to this limitation,
any access to the hardware registers in the absence of refclk will result
in a whole endpoint crash. Unfortunately, most of the controller cleanups
require accessing the hardware registers (like eDMA cleanup performed in
dw_pcie_ep_cleanup(), powering down MHI EPF etc...). So these cleanup
functions are currently causing the crash in the endpoint SoC once host
asserts PERST#.

One way to address this issue is by generating the refclk in the endpoint
itself and not depending on the host. But that is not always possible as
some of the endpoint designs do require the endpoint to consume refclk from
the host (as I was told by the Qcom engineers).

Thus, fix this crash by moving the controller cleanups to the start of
the qcom_pcie_perst_deassert() function. qcom_pcie_perst_deassert() is
called whenever the host has deasserted PERST# and it is guaranteed that
the refclk would be active at this point. So at the start of this function
(after enabling resources), the controller cleanup can be performed. Once
finished, rest of the code execution for PERST# deassert can continue as
usual.

Fixes: 570d7715eed8 ("PCI: dwc: ep: Introduce dw_pcie_ep_cleanup() API for drivers supporting PERST#")

OPP table is a generic property that is also required by other Qcom
platforms.

Hence move this property to qcom,pcie-common.yaml so that PCIe on other
Qcom platforms is able to adjust power domain performance state and ICC
peak bandwidth according to the given PCIe generation speed and link
width.

Subject: [PATCH 1399/2948] dt-bindings: PCI: qcom,pcie-x1e80100: Add 'global'
 interrupt
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Qcom PCIe RC controllers are capable of generating 'global' SPI interrupt
to the host CPU. This interrupt can be used by the device driver to handle
PCIe link specific events such as Link up and Link down, which give the
driver a chance to start bus enumeration on its own when link is up and
initiate link training if link goes to a bad state. The PCIe driver can
still work without this interrupt but it will provide a nice user
experience when device gets plugged and removed.

Hence, document it in the binding along with the existing MSI interrupts.
Global interrupt is parsed as optional in driver, so adding it in bindings
will not break the ABI.

Subject: [PATCH 1400/2948] iio: dac: ad3552r: add high-speed platform driver

Add High Speed ad3552r platform driver.

The ad3552r DAC is controlled by a custom (fpga-based) DAC IP
through the current AXI backend, or similar alternative IIO backend.

Compared to the existing driver (ad3552r.c), that is a simple SPI
driver, this driver is coupled with a DAC IIO backend that finally
controls the ad3552r by a fpga-based "QSPI+DDR" interface, to reach
maximum transfer rate of 33MUPS using dma stream capabilities.

All commands involving QSPI bus read/write are delegated to the backend
through the provided APIs for bus read/write.

The ad7591 has reset, clr and ldac gpios. For the DAC to output data
continuously written to the data register the state of these gpios needs
to be set by the driver.

Add these gpios to the driver making them optional in case they are fixed
on the pcb.

Use devm_iio_device_register to automatically free the iio device.
since this is the last remaining resource that was not automatically
freed, we can drop the ".remove" callback.

Subject: [PATCH 1412/2948] iio: hid-sensors: Add proximity and attention IDs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The HID Usage Table at https://usb.org/sites/default/files/hut1_5.pdf
reserves:

- 0x4b2 for Human Proximity Range
Distance between a human and the computer. Default unit of
measure is meters;
https://www.usb.org/sites/default/files/hutrr39b_0.pdf

- 0x4bd for Human Attention Detected
Human-Presence sensors detect the presence of humans in the sensor’s
field-of-view using diverse and evolving technologies. Some presence
sensors are implemented with low resolution video cameras, which can
additionally track a subject’s attention (i.e. if the
user is ‘looking’ at the system with the integrated sensor).
A Human-Presence sensor, providing a Host with the user’s attention
state, allows the Host to optimize its behavior. For example, to
brighten/dim the system display, based on the user’s attention to the
system (potentially prolonging battery life). Default unit is
true/false;

We are going to introduce more proximity channels. Make proximity a
indexed channel now, in a simple patch, so the change can be easily
bisected if there are any issues.

Subject: [PATCH 1422/2948] iio: light: adux1020: write_event_config: use local
 variable for interrupt value

state parameter is currently an int, but it is actually a boolean.
iio_ev_state_store is actually using kstrtobool to check user input,
then gives the converted boolean value to write_event_config.  The code
in adux1020_write_event_config re-uses state parameter to store an
integer value. To prepare for updating the write_event_config signature
to use a boolean for state, introduce a new local int variable.

Subject: [PATCH 1423/2948] iio: fix write_event_config signature

write_event_config callback use an int for state, but it is actually a
boolean. iio_ev_state_store is actually using kstrtobool to check user
input, then gives the converted boolean value to write_event_config.

Fix signature and update all iio drivers to use the new signature.

This patch has been partially written using coccinelle with the
following script:

$ cat iio-bool.cocci
// Options: --all-includes

virtual patch

@c1@
identifier iioinfo;
identifier wecfunc;
@@
 static const struct iio_info iioinfo = {
        ...,
        .write_event_config =
(
 wecfunc
|
 &wecfunc
),
        ...,
 };

@@
identifier c1.wecfunc;
identifier indio_dev, chan, type, dir, state;
@@
 int wecfunc(struct iio_dev *indio_dev, const struct iio_chan_spec *chan, enum iio_event_type type, enum iio_event_direction dir,
-int
+bool
 state) {
  ...
 }

make coccicheck MODE=patch COCCI=iio-bool.cocci M=drivers/iio

Unfortunately, this script didn't match all files:
* all write_event_config callbacks using iio_device_claim_direct_scoped
  were not detected and not patched.
* all files that do not assign and declare the write_event_config
  callback in the same file.

iio.h was also manually updated.

The patch was build tested using allmodconfig config.

 Allegro MicroSystems ALS31300 3-D Linear Hall Effect Sensor

Document the bindings for the Allegro MicroSystems ALS31300 3-D Linear
Hall Effect Sensor controller by an I2C interface, mainly used in 3D
head-on motion sensing applications.

The device can be configured with different sensitivities in factory,
but the sensitivity value used to calculate value into the Gauss unit
is not available from registers, thus the sensitivity is provided by
the compatible/device-id string which is based on the part number as
described in the datasheet page 2.

Subject: [PATCH 1434/2948] iio: magnetometer: add Allegro MicroSystems
 ALS31300 3-D Linear Hall Effect driver

The Allegro MicroSystems ALS31300 is a 3-D Linear Hall Effect Sensor
mainly used for 3D head-on motion sensing applications.

The device is configured over I2C, and as part of the Sensor data the
temperature core is also provided.

While the device provides an IRQ gpio, it depends on a configuration
programmed into the internal EEPROM, thus only the default mode is
supported and buffered input via trigger is also supported to allow
streaming values with the same sensing timestamp.

The device can be configured with different sensitivities in factory,
but the sensitivity value used to calculate value into the Gauss
unit is not available from registers, thus the sensitivity is provided
by the compatible/device-id string which is based on the part number
as described in the datasheet page 2.

Subject: [PATCH 1435/2948] iio: events.h: add event identifier macros for
 differential channel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, there are 3 helper macros in iio/events.h to create event
identifiers:
- IIO_EVENT_CODE : create generic event identifier for differential and non
  differential channels
- IIO_MOD_EVENT_CODE : create event identifier for modified (non
  differential) channels
- IIO_UNMOD_EVENT_CODE : create event identifier for unmodified (non
  differential) channels

For differential channels, drivers are expected to use IIO_EVENT_CODE.
However, only one driver in drivers/iio currently uses it correctly,
leading to inconsistent event identifiers for differential channels that
don’t match the intended attributes (such as max1363.c that supports
differential channels, but only uses IIO_UNMOD_EVENT_CODE).

To prevent such issues in future drivers, a new helper macro,
IIO_DIFF_EVENT_CODE, is introduced to specifically create event identifiers
for differential channels. Only one helper is needed for differential
channels since they cannot have modifiers.

Additionally, the descriptions for IIO_MOD_EVENT_CODE and
IIO_UNMOD_EVENT_CODE have been updated to clarify that they are intended
for non-differential channels,

Subject: [PATCH 1436/2948] iio: adc: ad7280a: use IIO_DIFF_EVENT_CODE macro
 helper

The IIO_DIFF_EVENT_CODE macro helper was introduced to provide a more
specific alternative to the generic IIO_EVENT_CODE macro for handling
differential channels. This commit updates the code to use
IIO_DIFF_EVENT_CODE for better clarity and maintainability.

However, the current implementation incorrectly sets both chan1 and
chan2 to 0. To maintain compatibility and avoid breaking existing
user space applications, this behavior is preserved for now.

Subject: [PATCH 1442/2948] iio: chemical: bme680: Add triggered buffer support

Add triggered buffer and soft timestamp support. The available scan mask
enables all the channels of the sensor in order to follow the operation of
the sensor. The sensor basically starts to capture from all channels
as long as it enters into FORCED mode.

The bulk read, reads a total of 15 registers from the sensor, 0x1D..0x2B.
Even though some of those registers are not reported in the register map
of the device, this is how the BME680 Sensor API [1] proposes to do it.
This allows to have one bulk read instead of multiple ones.

Subject: [PATCH 1447/2948] staging: rtl8723bs: Remove no-op
 netdevice_notifier()

rtw_ndev_notifier_call() does not do anything other then
a netdev_dbg() + always returning NOTIFY_DONE.

Remove the no-op notifier.

This also fixes a WARN() when unbinding + rebinding the driver
which was caused by the remove() method not unregistering
the notifier.

Subject: [PATCH 1450/2948] staging: rtl8712: Remove driver using deprecated
 API wext
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This driver is in the staging area since 2010.

The following reasons lead to the removal:
- This driver generates maintenance workload for itself and for API wext
- A MAC80211 driver was available in 2016 time frame; This driver does
  not compile anymore but would be a better starting point than the
  current driver. Here the note from the TODO file:
  A replacement for this driver with MAC80211 support is available
  at https://github.com/chunkeey/rtl8192su
- no progress changing to mac80211
- Using this hardware is security wise not state of the art as WPA3 is
  not supported.

The longterm kernels will still support this hardware for years.

Find further discussions in the Link below.

From 8898f64f7ae4e60d48065812965a75d627bb9e55 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1451/2948] staging: fieldbus: Delete unused driver

Sven Van Asbroeck contributed this driver in 2019.

The following reasons lead to the removal:
- This driver generates maintenance workload
- only 11 patches during the last 3 years. Part of the patches seem to be
  motivated because of maintenance (for example - remove deprecated
  function)
- Maintainer lost interest, last "Reviewed-by:" is May 2021
- no blog about usage of this driver

The staging subsystem is the way for drivers into the kernel - at current
speed and interest this is never going to happen. I think that fieldbus
is an interesting topic. But when almost nobody cares about this driver,
it does not make sense to keep it. Please consider that support will
remain for years in the longterm kernels.

-KernelVersion:	5.1 (staging)
-Contact:	Sven Van Asbroeck <TheSven73@gmail.com>
-Description:
-		The cdev interface to drivers for Fieldbus Device Memory
-			(aka. Process Memory).
-
-		The following file operations are supported:
-
-		open(2)
-		Create an I/O context associated with the file descriptor.
-
-		read(2)
-		Read from Process Memory's "read area".
-		Clears POLLERR | POLLPRI from the file descriptor.
-
-		write(2)
-		Write to Process Memory's "write area".
-
-		poll(2), select(2), epoll_wait(2) etc.
-		When a "Process Memory Read Area Changed" event occurs,
-		POLLERR | POLLPRI will be set on the file descriptor.
-		Note that POLLIN | POLLOUT events are always set, because the
-		process memory area is always readable and writable.
-
-		close(2)
-		Free up the I/O context that was associated
-		with the file descriptor.
-

-* Arcx Anybus-S controller
-
-This chip communicates with the SoC over a parallel bus. It is
-expected that its Device Tree node is specified as the child of a node
-corresponding to the parallel bus used for communication.
-
-Required properties:
---------------------
-
-  - compatible : The following chip-specific string:
-        "arcx,anybus-controller"
-
-  - reg : three areas:
-	index 0: bus memory area where the cpld registers are located.
-	index 1: bus memory area of the first  host's dual-port ram.
-	index 2: bus memory area of the second host's dual-port ram.
-
-  - reset-gpios : the GPIO pin connected to the reset line of the controller.
-
-  - interrupts : two interrupts:
-		index 0: interrupt connected to the first  host
-		index 1: interrupt connected to the second host
-	Generic interrupt client node bindings are described in
-	interrupt-controller/interrupts.txt
-
-Optional: use of subnodes
--------------------------
-
-The card connected to a host may need additional properties. These can be
-specified in subnodes to the controller node.
-
-The subnodes are identified by the standard 'reg' property. Which information
-exactly can be specified depends on the bindings for the function driver
-for the subnode.
-
-Required controller node properties when using subnodes:
-- #address-cells: should be one.
-- #size-cells: should be zero.
-
-Required subnode properties:
-- reg: Must contain the host index of the card this subnode describes:
-		<0>	for the first  host on the controller
-		<1>	for the second host on the controller
-	Note that only a single card can be plugged into a host, so the host
-	index uniquely describes the card location.
-
-Example of usage:
------------------
-
-This example places the bridge on top of the i.MX WEIM parallel bus, see:
-Documentation/devicetree/bindings/memory-controllers/fsl/fsl,imx-weim.yaml
-
-&weim {
-	controller@0,0 {
-		compatible = "arcx,anybus-controller";
-		reg = <0 0 0x100>, <0 0x400000 0x800>, <1 0x400000 0x800>;
-		reset-gpios = <&gpio5 2 GPIO_ACTIVE_HIGH>;
-		interrupt-parent = <&gpio1>;
-		interrupts = <1 IRQ_TYPE_LEVEL_LOW>, <5 IRQ_TYPE_LEVEL_LOW>;
-		/* fsl,weim-cs-timing is a i.MX WEIM bus specific property */
-		fsl,weim-cs-timing = <0x024400b1 0x00001010 0x20081100
-				0x00000000 0xa0000240 0x00000000>;
-		/* optional subnode for a card plugged into the first host */
-		#address-cells = <1>;

-                       Fieldbus-Device Subsystem
-               ============================================
-
-Part 0 - What is a Fieldbus Device ?
-------------------------------------
-
-Fieldbus is the name of a family of industrial computer network protocols used
-for real-time distributed control, standardized as IEC 61158.
-
-A complex automated industrial system -- such as manufacturing assembly line --
-usually needs a distributed control system -- an organized hierarchy of
-controller systems -- to function. In this hierarchy, there is usually a
-Human Machine Interface (HMI) at the top, where an operator can monitor or
-operate the system. This is typically linked to a middle layer of programmable
-logic controllers (PLC) via a non-time-critical communications system
-(e.g. Ethernet). At the bottom of the control chain is the fieldbus that links
-the PLCs to the components that actually do the work, such as sensors,
-actuators, electric motors, console lights, switches, valves and contactors.
-
-(Source: Wikipedia)
-
-A "Fieldbus Device" is such an actuator, motor, console light, switch, ...
-controlled via the Fieldbus by a PLC aka "Fieldbus Controller".
-
-Communication between PLC and device typically happens via process data memory,
-separated into input and output areas. The Fieldbus then cyclically transfers
-the PLC's output area to the device's input area, and vice versa.
-
-Part I - Why do we need this subsystem?
----------------------------------------
-
-Fieldbus device (client) adapters are commercially available. They allow data
-exchange with a PLC aka "Fieldbus Controller" via process data memory.
-
-They are typically used when a Linux device wants to expose itself as an
-actuator, motor, console light, switch, etc. over the fieldbus.
-
-The purpose of this subsystem is:
-a) present a general, standardized, extensible API/ABI to userspace; and
-b) present a convenient interface to drivers.
-
-Part II - How can drivers use the subsystem?
---------------------------------------------
-
-Any driver that wants to register as a Fieldbus Device should allocate and
-populate a 'struct fieldbus_dev' (from include/linux/fieldbus_dev.h).
-Registration then happens by calling fieldbus_dev_register().
-
-Part III - How can userspace use the subsystem?
------------------------------------------------
-
-Fieldbus protocols and adapters are diverse and varied. However, they share
-a limited few common behaviours and properties. This allows us to define
-a simple interface consisting of a character device and a set of sysfs files:
-
-See:
-drivers/staging/fieldbus/Documentation/ABI/sysfs-class-fieldbus-dev
-drivers/staging/fieldbus/Documentation/ABI/fieldbus-dev-cdev
-
-Note that this simple interface does not provide a way to modify adapter
-configuration settings. It is therefore useful only for adapters that get their
-configuration settings some other way, e.g. non-volatile memory on the adapter,
-through the network, ...
-
-At a later phase, this simple interface can easily co-exist with a future
-(netlink-based ?) configuration settings interface.

-/*
- * Architecture Overview
- * =====================
- * This driver (running on the CPU/SoC) and the Anybus-S card communicate
- * by reading and writing data to/from the Anybus-S Dual-Port RAM (dpram).
- * This is memory connected to both the SoC and Anybus-S card, which both sides
- * can access freely and concurrently.
- *
- * Synchronization happens by means of two registers located in the dpram:
- * IND_AB: written exclusively by the Anybus card; and
- * IND_AP: written exclusively by this driver.
- *
- * Communication happens using one of the following mechanisms:
- * 1. reserve, read/write, release dpram memory areas:
- *	using an IND_AB/IND_AP protocol, the driver is able to reserve certain
- *	memory areas. no dpram memory can be read or written except if reserved.
- *	(with a few limited exceptions)
- * 2. send and receive data structures via a shared mailbox:
- *	using an IND_AB/IND_AP protocol, the driver and Anybus card are able to
- *	exchange commands and responses using a shared mailbox.
- * 3. receive software interrupts:
- *	using an IND_AB/IND_AP protocol, the Anybus card is able to notify the
- *	driver of certain events such as: bus online/offline, data available.
- *	note that software interrupt event bits are located in a memory area
- *	which must be reserved before it can be accessed.
- *
- * The manual[1] is silent on whether these mechanisms can happen concurrently,
- * or how they should be synchronized. However, section 13 (Driver Example)
- * provides the following suggestion for developing a driver:
- * a) an interrupt handler which updates global variables;
- * b) a continuously-running task handling area requests (1 above)
- * c) a continuously-running task handling mailbox requests (2 above)
- * The example conspicuously leaves out software interrupts (3 above), which
- * is the thorniest issue to get right (see below).
- *
- * The naive, straightforward way to implement this would be:
- * - create an isr which updates shared variables;
- * - create a work_struct which handles software interrupts on a queue;
- * - create a function which does reserve/update/unlock in a loop;
- * - create a function which does mailbox send/receive in a loop;
- * - call the above functions from the driver's read/write/ioctl;
- * - synchronize using mutexes/spinlocks:
- *	+ only one area request at a time
- *	+ only one mailbox request at a time
- *	+ protect AB_IND, AB_IND against data hazards (e.g. read-after-write)
- *
- * Unfortunately, the presence of the software interrupt causes subtle yet
- * considerable synchronization issues; especially problematic is the
- * requirement to reserve/release the area which contains the status bits.
- *
- * The driver architecture presented here sidesteps these synchronization issues
- * by accessing the dpram from a single kernel thread only. User-space throws
- * "tasks" (i.e. 1, 2 above) into a task queue, waits for their completion,
- * and the kernel thread runs them to completion.
- *
- * Each task has a task_function, which is called/run by the queue thread.
- * That function communicates with the Anybus card, and returns either
- * 0 (OK), a negative error code (error), or -EINPROGRESS (waiting).
- * On OK or error, the queue thread completes and dequeues the task,
- * which also releases the user space thread which may still be waiting for it.
- * On -EINPROGRESS (waiting), the queue thread will leave the task on the queue,
- * and revisit (call again) whenever an interrupt event comes in.
- *
- * Each task has a state machine, which is run by calling its task_function.
- * It ensures that the task will go through its various stages over time,
- * returning -EINPROGRESS if it wants to wait for an event to happen.
- *
- * Note that according to the manual's driver example, the following operations
- * may run independent of each other:
- * - area reserve/read/write/release	(point 1 above)
- * - mailbox operations			(point 2 above)
- * - switching power on/off
- *
- * To allow them to run independently, each operation class gets its own queue.
- *
- * Userspace processes A, B, C, D post tasks to the appropriate queue,
- * and wait for task completion:
- *
- *	process A	B	C	D

- *		+--------------------------------------+
- *
- * Note that the Anybus interrupt is dual-purpose:
- * - after a reset, triggered when the card becomes ready;
- * - during normal operation, triggered when AB_IND changes.
- * This is why the interrupt service routine doesn't just wake up the
- * queue thread, but also completes the card_boot completion.

Subject: [PATCH 1453/2948] staging: vchiq_core: Bulk waiter should not piggy
 back on bulk userdata

Currently, struct bulk_waiter is allocated for VCHIQ_BULK_MODE_BLOCKING
bulk transfer and its pointer is assigned to vchiq_bulk->userdata. Avoid
this kind of piggybacking and introduce a dedicate 'waiter' member in
struct vchiq_bulk.

The 'userdata' is meant for VCHIQ_BULK_MODE_CALLBACK mode, to pass user
specified parameter to the actual callback function.

Subject: [PATCH 1454/2948] staging: vchiq_core: Rename struct vchiq_bulk
 'userdata'

Rename the struct vchiq_bulk 'userdata' member to 'cb_data' to clarify
its purpose. 'cb_data' is meant to be passed to service callback
function in VCHIQ_BULK_MODE_CALLBACK mode.

No functional changes in this patch.

Subject: [PATCH 1455/2948] staging: vchiq: Rename vchiq_completion_data
 'bulk_userdata'

In a previous commit, struct vchiq_bulk 'userdata' got renamed to
'cb_data' since it is the data pointer passed in
VCHIQ_BULK_CALLBACK_MODE's callback. Since struct vchiq_completion_data*
structs also has 'bulk_userdata' for completion records, rename
'bulk_userdata' member to 'cb_data' for these structs as well.

This brings consistency and clarity for the struct members. No
functional change in this patch.

Subject: [PATCH 1457/2948] staging: vchiq_arm: Track bulk user data pointer
 separately

A bulk callback transfer can be initiated from two places -
inside kernel interface or from user interface. However,
the callback data pointer 'cb_data' is used for tracking both
sets of data pointer. This commit tracks the callback
data pointer from user interface (named as 'cb_userdata') separately,
in the bulk transfer service callback.

This is esentially done by adding a 'void __user *cb_userdata' for
tracking __user pointers in vchiq_bulk and vchiq_completion_data
structs. Furthermore, the 'cb_userdata' data pointer is appended to
the vchiq_service's callback signature.

Separating the two callback data pointers ('cb_data' and 'cb_userdata')
fixes the sparse warnings around mixing userspace and kernel space
pointers.

As there are no additional sparse warnings left for vc04_services,
drop the relevant entry from the TODO.

Subject: [PATCH 1473/2948] USB: xhci: add support for PWRON active high

Some PCIe-to-USB controllers such as TI's TUSB73x0 3.0 xHCI host
controller supports controlling the PWRONx polarity via the USB control
register (E0h). Add support for device tree property
ti,pwron-active-high which indicates PWRONx to be active high and
configure the E0h register accordingly.  This enables the software
control for the TUSB73x0's PWRONx outputs with an inverted polarity from
the default configuration which could be used as USB EN signals for the
other hubs or devices.

Subject: [PATCH 1475/2948] usb: typec: mux: Add support for the TUSB1046
 crosspoint switch

The TUSB1046-DCI is a USB-C linear redriver crosspoint switch, which can
mux SuperSpeed lanes from a Type-C connector to a USB3.0 data lane or up to
4 display port lanes.

Add support for driving the TUSB1046 as a Type-C orientation switch and
DisplayPort altmode multiplexer.

SG2044 relys on an internal divisor when calculating bitrate, which
means a wrong clock for the most common bitrates. So add a quirk for
this uart device to skip the set rate call and only relys on the
internal UART divisor.

Since commit b1992c3772e6 ("kbuild: use $(src) instead of
$(srctree)/$(src) for source directory"), $(src) consistently points
to the source directory, regardless of whether it is compiled as an
external module or not.

Subject: [PATCH 1491/2948] kbuild: check the presence of
 include/generated/rustc_cfg

Since commit 2f7ab1267dc9 ("Kbuild: add Rust support"), Kconfig
generates include/generated/rustc_cfg, but its presence is not checked
in the top-level Makefile. It should be checked similarly to the C
header counterpart, include/generated/autoconf.h.

Subject: [PATCH 1492/2948] kbuild: add generic support for built-in boot DTBs

Some architectures embed boot DTBs in vmlinux. A potential issue for
these architectures is a race condition during parallel builds because
Kbuild descends into arch/*/boot/dts/ twice.

One build thread is initiated by the 'dtbs' target, which is a
prerequisite of the 'all' target in the top-level Makefile:

  ifdef CONFIG_OF_EARLY_FLATTREE
  all: dtbs
  endif

For architectures that support the built-in boot dtb, arch/*/boot/dts/
is visited also during the ordinary directory traversal in order to
build obj-y objects that wrap DTBs.

Since these build threads are unaware of each other, they can run
simultaneously during parallel builds.

This commit introduces a generic build rule to scripts/Makefile.vmlinux
to support embedded boot DTBs in a race-free way. Architectures that
want to use this rule need to select CONFIG_GENERIC_BUILTIN_DTB.

After the migration, Makefiles under arch/*/boot/dts/ will be visited
only once to build only *.dtb files.

This change also aims to unify the CONFIG options used for built-in DTBs
support. Currently, different architectures use different CONFIG options
for the same purposes.

With this commit, the CONFIG options will be unified as follows:

 - CONFIG_GENERIC_BUILTIN_DTB

   This enables the generic rule for built-in boot DTBs. This will be
   renamed to CONFIG_BUILTIN_DTB after all architectures migrate to the
   generic rule.

 - CONFIG_BUILTIN_DTB_NAME

   This specifies the path to the embedded DTB.
   (relative to arch/*/boot/dts/)

 - CONFIG_BUILTIN_DTB_ALL

   If this is enabled, all DTB files compiled under arch/*/boot/dts/ are
   embedded into vmlinux. Only used by MIPS.

Subject: [PATCH 1493/2948] usb: use "prompt" instead of "bool" for choice
 prompts

Since commit fde192511bdb ("kconfig: remove tristate choice support"),
all choice blocks are now boolean. There is no longer a need to specify
the choice type explicitly.

Most choice blocks already use "prompt". Before the next commit removes
support for the "bool" syntax in choice entries, this commit converts
the remaining "bool" occurences under drivers/usb/.

Subject: [PATCH 1502/2948] iTCO_wdt: mask NMI_NOW bit for
 update_no_reboot_bit() call

Commit da23b6faa8bf ("watchdog: iTCO: Add support for Cannon Lake
PCH iTCO") does not mask NMI_NOW bit during TCO1_CNT register's
value comparison for update_no_reboot_bit() call causing following
failure:

   ...
   iTCO_vendor_support: vendor-support=0
   iTCO_wdt iTCO_wdt: unable to reset NO_REBOOT flag, device
                                    disabled by hardware/BIOS
   ...

and this can lead to unexpected NMIs later during regular
crashkernel's workflow because of watchdog probe call failures.

This change masks NMI_NOW bit for TCO1_CNT register values to
avoid unexpected NMI_NOW bit inversions.

Subject: [PATCH 1503/2948] watchdog: xilinx_wwdt: Calculate
 max_hw_heartbeat_ms using clock frequency

In the current implementation, the value of max_hw_heartbeat_ms is set
to the timeout period expressed in milliseconds and fails to verify if
the close window percentage exceeds the maximum value that the hardware
supports.

1. Calculate max_hw_heartbeat_ms based on input clock frequency.
2. Update frequency check to require a minimum frequency of 1Mhz.
3. Limit the close and open window percent to hardware supported value
to avoid truncation.
4. If the user input timeout exceeds the maximum timeout supported, use
only open window and the framework supports the higher timeouts.

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The STM32MP15xx IWDG adds registers which permit this IP to generate
pretimeout interrupt. This interrupt can also be used to wake the CPU
from suspend. Implement support for generating this interrupt and let
userspace configure the pretimeout. In case the pretimeout is not
configured by user, set pretimeout to 3/4 of the WDT timeout cycle.

Although there is an existing code comment about flushing the writes,
writes were not actually being flushed.

Actually flush the writes by changing readl_relaxed() to readl().

 PCIE_T_PVPERL_MS milliseconds
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

According to Section 2.2 of the PCI Express Card Electromechanical
Specification (Revision 5.1), in order to ensure that the power and the
reference clock are stable, PERST# has to be deasserted after a delay of
100 milliseconds (TPVPERL).

Currently, it is being assumed that the power is already stable, which
is not necessarily true.

Hence, change the delay to PCIE_T_PVPERL_MS to guarantee that power and
reference clock are stable.

The SC8280XP PCIe devicetree nodes do not specify an 'iommu-map' so
the config_sid() callback is effectively a no-op.

Hence introduce a new ops struct, namely ops_1_21_0 which is same as
ops_1_9_0 except that it doesn't have config_sid() callback to clean
it up.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, the cfg_1_9_0 which is being used for X1E80100 doesn't disable
ASPM L0s. However, hardware team recommends to disable L0s as the PHY init
sequence is not tuned support L0s. Hence reuse cfg_sc8280xp for X1E80100.

Note that the config_sid() callback is not present in cfg_sc8280xp, don't
concern about this because config_sid() callback is originally a no-op
for X1E80100.

 max-link-speed limit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for respecting the max-link-speed devicetree property,
forcing a maximum speed (Gen) for a PCI-Express port.

Since the MediaTek PCIe Gen3 controllers also expose the maximum
supported link speed in the PCIE_BASE_CFG register, if property
max-link-speed is specified in devicetree, validate it against the
controller capabilities and proceed setting the limitations only
if the wanted Gen is lower than the maximum one that is supported
by the controller itself (otherwise it makes no sense!).

Subject: [PATCH 1515/2948] perf build: Make libunwind opt-in rather than
 opt-out

Having multiple unwinding libraries makes the perf code harder to
understand and we have unused/untested code paths.

Perf made BPF support an opt-out rather than opt-in feature. As libbpf
has a libelf dependency, elfutils that provides libelf will also
provide libdw. When libdw is present perf will use libdw unwinding
rather than libunwind unwinding even if libunwind support is compiled
in.

Rather than have libunwind built into perf and never used, explicitly
disable the support and make it opt-in.

Subject: [PATCH 1516/2948] rust: add static_branch_unlikely for
 static_key_false

Add just enough support for static key so that we can use it from
tracepoints. Tracepoints rely on `static_branch_unlikely` with a `struct
static_key_false`, so we add the same functionality to Rust.

This patch only provides a generic implementation without code patching
(matching the one used when CONFIG_JUMP_LABEL is disabled). Later
patches add support for inline asm implementations that use runtime
patching.

When CONFIG_JUMP_LABEL is unset, `static_key_count` is a static inline
function, so a Rust helper is defined for `static_key_count` in this
case. If Rust is compiled with LTO, this call should get inlined. The
helper can be eliminated once we have the necessary inline asm to make
atomic operations from Rust.

Subject: [PATCH 1517/2948] rust: add tracepoint support

Make it possible to have Rust code call into tracepoints defined by C
code. It is still required that the tracepoint is declared in a C
header, and that this header is included in the input to bindgen.

Instead of calling __DO_TRACE directly, the exported rust_do_trace_
function calls an inline helper function. This is because the `cond`
argument does not exist at the callsite of DEFINE_RUST_DO_TRACE.

__DECLARE_TRACE always emits an inline static and an extern declaration
that is only used when CREATE_RUST_TRACE_POINTS is set. These should not
end up in the final binary so it is not a problem that they sometimes
are emitted without a user.

Subject: [PATCH 1519/2948] jump_label: adjust inline asm to be consistent

To avoid duplication of inline asm between C and Rust, we need to
import the inline asm from the relevant `jump_label.h` header into Rust.
To make that easier, this patch updates the header files to expose the
inline asm via a new ARCH_STATIC_BRANCH_ASM macro.

The header files are all updated to define a ARCH_STATIC_BRANCH_ASM that
takes the same arguments in a consistent order so that Rust can use the
same logic for every architecture.

From 169484ab667788e73d1817d75c2a2c4af37dbc7f Mon Sep 17 00:00:00 2001
From: Alice Ryhl <aliceryhl@google.com>
Date: Wed, 30 Oct 2024 16:04:28 +0000
Subject: [PATCH 1520/2948] rust: add arch_static_branch

To allow the Rust implementation of static_key_false to use runtime code
patching instead of the generic implementation, pull in the relevant
inline assembly from the jump_label.h header by running the C
preprocessor on a .rs.S file. Build rules are added for .rs.S files.

Since the relevant inline asm has been adjusted to export the inline asm
via the ARCH_STATIC_BRANCH_ASM macro in a consistent way, the Rust side
does not need architecture specific code to pull in the asm.

It is not possible to use the existing C implementation of
arch_static_branch via a Rust helper because it passes the argument
`key` to inline assembly as an 'i' parameter. Any attempt to add a C
helper for this function will fail to compile because the value of `key`
must be known at compile-time.

Subject: [PATCH 1521/2948] PCI: dwc: endpoint: Implement the
 pci_epc_ops::align_addr() operation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The function dw_pcie_prog_outbound_atu() used to program outbound ATU
entries for mapping RC PCI addresses to local CPU addresses does not
allow PCI addresses that are not aligned to the value of region_align
of struct dw_pcie. This value is determined from the iATU hardware
registers during probing of the iATU (done by dw_pcie_iatu_detect()).
This value is thus valid for all DWC PCIe controllers, and valid
regardless of the hardware configuration used when synthesizing the
DWC PCIe controller.

Implement the ->align_addr() endpoint controller operation to allow
this mapping alignment to be transparently handled by endpoint function
drivers through the function pci_epc_mem_map().

 handler work
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use cancel_delayed_work_sync() in pci_epf_test_epc_deinit() to ensure
that the command handler is really stopped before proceeding with DMA
and BAR cleanup.

The same change is also done in pci_epf_test_link_down() to ensure that
the link down handling completes with the command handler fully stopped.

Fix the following compilation warning:

  925 | static const struct acpi_device_id goldfish_pipe_acpi_match[] = {

The complexity of config guards needed for ACPI_PTR() is not worthwhile
for the small amount of saved data. So remove the use of ACPI_PTR instead
and drop now unneeded linux/acpi.h include.

Subject: [PATCH 1531/2948] dt-bindings: fuse: Move renesas,rcar-{efuse,otp} to
 nvmem

The R-Car E-FUSE blocks can be modelled better using the nvmem
framework.

Replace the R-Car V3U example by an R-Car S4-8 ES1.2 example, to show
the definition of nvmem cells.  While at it, drop unneeded labels from
the examples, and fix indentation.

Add an entry to the MAINTAINERS file.

Subject: [PATCH 1532/2948] nvmem: Add R-Car E-FUSE driver

R-Car Gen4 SoCs contain fuses indicating hardware support or hardware
(e.g. tuning) parameters.  Add a driver to access the state of the
fuses.  This supports two types of hardware fuse providers:
  1. E-FUSE non-volatile memory accessible through the Pin Function
     Controller on R-Car V3U and S4-8,
  2. E-FUSE non-volatile memory accessible through OTP_MEM on R-Car V4H
     and V4M.

The state of the cells can be read using the NVMEM framework, either
from kernel space (e.g. by the Renesas UFSHCD driver), or from
userspace.

Subject: [PATCH 1536/2948] dt-bindings: nvmem: sprd,ums312-efuse: convert to
 YAML

Convert the Spreadtrum UMS312 eFuse bindings to DT schema.
Adjust filename to match compatible.

Note: the UMS312 clock bindings include doesn't seem to exist (yet?), so
      the UMS512 one was used for the "CLK_EFUSE_EB" define.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers matched by the "CHAR and MISC DRIVERS"
maintainer's entry to use .remove(), with the eventual goal to drop
struct platform_driver::remove_new(). As .remove() and .remove_new()
have the same prototypes, conversion is done by just changing the
structure member name in the driver initializer.

Subject: [PATCH 1548/2948] perf test: Remove cpu-list BPF cgroup counter test

The cpu-list part of this testcase has proven itself to be unreliable.
Sometimes, we get "<not counted>" for system.slice when pinned to CPUs
0 and 1. In such case, the test fails.

Since we cannot simply guarantee that any system.slice load will run
on any arbitrary list of CPUs, except the whole set of all CPUs, let's
rather remove the cpu-list subtest.

Subject: [PATCH 1552/2948] perf test: Fix ftrace test with regex patterns

During the parallel testing, I've noticed some ftrace test failures.  It
seems the regex pattern checks 100 msec of nanosleep with the error
range of 10 msec.  But sometimes it's affected by other processes and
resulted in more time in the syscall.

The following output shows that it took more than 120 msec and failed.
Let's update the regex pattern so that it can allow more drifts.

Subject: [PATCH 1553/2948] watchdog: always print when registering watchdog
 fails

So far, only 'watchdog_register_device' prints an error if registering
the watchdog driver fails. '__watchdog_register_device' doesn't.
Refactor the code so that both print out. Drivers can then rely on that
and skip their own error messages.

 for Airoha EN7581

Document watchdog for Airoha EN7581. This SoC implement a simple
watchdog that supports a max timeout of 28 seconds.

The watchdog ticks on half the BUS clock and requires the BUS clock to be
referenced.

Subject: [PATCH 1563/2948] watchdog: Add support for Airoha EN7851 watchdog

Add support for Airoha EN7851 watchdog. This is a very basic watchdog
with no pretimeout support, max timeout is 28 seconds and it ticks based
on half the SoC BUS clock.

Subject: [PATCH 1564/2948] watchdog: Delete the cpu5wdt driver

This driver has a number of issues (accesses arbitrary I/O ports
without identifying the hardware, doesn't document what hardware it
supports, suspiciously inconsistent locking model, doesn't implement
WDIOC_SETTIMEOUT, potential integer overflow...)

The driver was added in 2003 and there's no evidence that it has any
recent user, all changes seem to be tree-wide, subsystem-wide, or the
result of static code analysis. So I believe we should simply drop
this legacy piece of code.

Subject: [PATCH 1565/2948] watchdog: da9063: Do not use a global variable

Using the 'use_sw_pm' variable as global is not recommended
as it prevents multi instances of the driver to run.

Make it a member of the da9063 structure instead.

Subject: [PATCH 1566/2948] watchdog: da9063: Remove __maybe_unused notations

Use the DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to
handle the .suspend/.resume callbacks.

These macros allow the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_SUSPEND is disabled, without having
to use __maybe_unused notation.

Subject: [PATCH 1567/2948] watchdog: it87_wdt: add PWRGD enable quirk for
 Qotom QCML04

For the watchdog timer to work properly on the QCML04 board we need to
set PWRGD enable in the Environment Controller Configuration Registers
Special Configuration Register 1 when it is not already set, this may
be the case when the watchdog is not enabled from within the BIOS.

Subject: [PATCH 1568/2948] watchdog: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/watchdog/ to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

While touching these files, make indention of the struct initializer
consistent in several files.

Subject: [PATCH 1569/2948] watchdog: rzg2l_wdt: Power on the watchdog domain
 in the restart handler

On RZ/G3S the watchdog can be part of a software-controlled PM domain. In
this case, the watchdog device need to be powered on in
struct watchdog_ops::restart API. This can be done though
pm_runtime_resume_and_get() API if the watchdog PM domain and watchdog
device are marked as IRQ safe. We mark the watchdog PM domain as IRQ safe
with GENPD_FLAG_IRQ_SAFE when the watchdog PM domain is registered and the
watchdog device though pm_runtime_irq_safe().

Before commit e4cf89596c1f ("watchdog: rzg2l_wdt: Fix 'BUG: Invalid wait
context'") pm_runtime_get_sync() was used in watchdog restart handler
(which is similar to pm_runtime_resume_and_get() except the later one
handles the runtime resume errors).

Commit e4cf89596c1f ("watchdog: rzg2l_wdt: Fix 'BUG: Invalid wait
context'") dropped the pm_runtime_get_sync() and replaced it with
clk_prepare_enable() to avoid invalid wait context due to genpd_lock()
in genpd_runtime_resume() being called from atomic context. But
clk_prepare_enable() doesn't fit for this either (as reported by
Ulf Hansson) as clk_prepare() can also sleep (it just not throw invalid
wait context warning as it is not written for this).

Because the watchdog device is marked now as IRQ safe (though this patch)
the irq_safe_dev_in_sleep_domain() call from genpd_runtime_resume() returns
1 for devices not registering an IRQ safe PM domain for watchdog (as the
watchdog device is IRQ safe, PM domain is not and watchdog PM domain is
always-on), this being the case for RZ/G3S with old device trees and
the rest of the SoCs that use this driver, we can now drop also the
clk_prepare_enable() calls in restart handler and rely on
pm_runtime_resume_and_get().

Thus, drop clk_prepare_enable() and use pm_runtime_resume_and_get() in
watchdog restart handler.

Subject: [PATCH 1570/2948] fuse: support folios in struct fuse_args_pages and
 fuse_copy_pages()

This adds support in struct fuse_args_pages and fuse_copy_pages() for
using folios instead of pages for transferring data. Both folios and
pages must be supported right now in struct fuse_args_pages and
fuse_copy_pages() until all request types have been converted to use
folios. Once all have been converted, then
struct fuse_args_pages and fuse_copy_pages() will only support folios.

Right now in fuse, all folios are one page (large folios are not yet
supported). As such, copying folio->page is sufficient for copying
the entire folio in fuse_copy_pages().

No functional changes.

Subject: [PATCH 1571/2948] fuse: add support in virtio for requests using
 folios

Until all requests have been converted to use folios instead of pages,
virtio will need to support both types. Once all requests have been
converted, then virtio will support just folios.

No functional changes.

Subject: [PATCH 1580/2948] mm/writeback: add folio_mark_dirty_lock()

Add a new convenience helper folio_mark_dirty_lock() that grabs the
folio lock before calling folio_mark_dirty().

Refactor set_page_dirty_lock() to directly use folio_mark_dirty_lock().

Subject: [PATCH 1582/2948] gfs2: Faster gfs2_upgrade_iopen_glock wakeups

Move function needs_demote() to glock.h and rename it to
glock_needs_demote().  In handle_callback(), wake up the glock when
setting the GLF_PENDING_DEMOTE flag as well.  (Setting the GLF_DEMOTE
flag already triggered a wake-up.)

With that, check for glock_needs_demote() in gfs2_upgrade_iopen_glock()
to wake up when either of those flags is set for the inode glock: the
faster we can react to contention, the better.

The GLF_PENDING_DEMOTE flag is only used for inode glocks (see
gfs2_glock_cb()) so it's okay to only check for the GLF_DEMOTE flag in
gfs2_drop_inode().  Still, using glock_needs_demote() there as well
makes the code a little easier to read.

Rename enum dinode_demise to evict_behavior and its items
SHOULD_DELETE_DINODE to EVICT_SHOULD_DELETE,
SHOULD_NOT_DELETE_DINODE to EVICT_SHOULD_SKIP_DELETE, and
SHOULD_DEFER_EVICTION to EVICT_SHOULD_DEFER_DELETE.

In gfs2_evict_inode(), add a separate variable of type enum
evict_behavior instead of implicitly casting to int.

Function delete_work_func() was previously assuming that the

same time, but there probably are races in which that can happen, so
handle that case correctly.

 gfs2_queue_try_to_evict

In the unlikely case that we're trying to queue GLF_TRY_TO_EVICT work
for an inode that already has GLF_VERIFY_DELETE work queued, we want to
make sure that the GLF_TRY_TO_EVICT work gets scheduled immediately
instead of waiting for the delayed work timer to expire.

Subject: [PATCH 1594/2948] gfs2: gfs2_evict_inode clarification

When function evict_should_delete() returns SHOULD_DEFER_EVICTION, gh is
never initialized, but that isn't obvious; if it did initialize gh and
then return SHOULD_DEFER_EVICTION, gfs2_evict_inode() would fail to
release it.  To clarify the code, change gfs2_evict_inode() to always
check if gh needs to be released, no matter what evict_should_delete()
returns.

Subject: [PATCH 1595/2948] gfs2: Simplify DLM_LKF_QUECVT use

The DLM_LKF_QUECVT flag needs to be set for "upward" lock conversions to
ensure fairness, but setting it for "downward" lock conversions will
lead to a failure.  The flag is currently set based on the GLF_BLOCKING
flag and it's not immediately obvious why this is correct.  Simplify
things by figuring out if a lock conversion is "upward" by looking at
the before and after locking modes instead of relying on the
GLF_BLOCKING flag.

Subject: [PATCH 1597/2948] usb: Use (of|device)_property_present() for
 non-boolean properties

The use of (of|device)_property_read_bool() for non-boolean properties
is deprecated in favor of of_property_present() when testing for
property presence.

MIME-Version: 1.0

Upcoming changes to the sysfs core require the size of the created file
to be overridable by the caller.
Add a parameter to enable this.
For now keep using attr->size in all cases.

Subject: [PATCH 1599/2948] sysfs: introduce callback attribute_group::bin_size
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Several drivers need to dynamically calculate the size of an binary
attribute. Currently this is done by assigning attr->size from the
is_bin_visible() callback.

This has drawbacks:
* It is not documented.
* A single attribute can be instantiated multiple times, overwriting the
  shared size field.
* It prevents the structure to be moved to read-only memory.

Introduce a new dedicated callback to calculate the size of the
attribute.

The is_bin_visible() callbacks should not modify the struct
bin_attribute passed as argument.
Enforce this by marking the argument as const.

As there are not many callback implementers perform this change
throughout the tree at once.

Subject: [PATCH 1603/2948] sysfs: treewide: constify attribute callback of
 bin_attribute::mmap()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The mmap() callbacks should not modify the struct
bin_attribute passed as argument.
Enforce this by marking the argument as const.

As there are not many callback implementers perform this change
throughout the tree at once.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

The preparations for the upcoming constification of struct bin_attribute
requires some logic in the structure definition macros.
To avoid duplication of that logic in multiple macros, reimplement all
other macros in terms of __BIN_ATTR().

Subject: [PATCH 1606/2948] sysfs: bin_attribute: add const read/write callback
 variants
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To make it possible to put struct bin_attribute into read-only memory,
the sysfs core has to stop passing mutable pointers to the read() and
write() callbacks.
As there are numerous implementors of these callbacks throughout the
tree it's not possible to change all of them at once.
To enable a step-by-step transition, add new variants of the read() and
write() callbacks which differ only in the constness of the struct
bin_attribute argument.

As most binary attributes are defined through macros, extend these
macros to transparently handle both variants of callbacks to minimize
the churn during the transition.
As soon as all handlers are switch to the const variant, the non-const
one can be removed together with the transition machinery.

Subject: [PATCH 1608/2948] comedi: Flush partial mappings in error case

If some remap_pfn_range() calls succeeded before one failed, we still have
buffer pages mapped into the userspace page tables when we drop the buffer
reference with comedi_buf_map_put(bm). The userspace mappings are only
cleaned up later in the mmap error path.

Fix it by explicitly flushing all mappings in our VMA on the error path.

See commit 79a61cc3fc04 ("mm: avoid leaving partial pfn mappings around in
error case").

Subject: [PATCH 1610/2948] driver core: fw_devlink: Stop trying to optimize
 cycle detection logic

In attempting to optimize fw_devlink runtime, I introduced numerous cycle
detection bugs by foregoing cycle detection logic under specific
conditions. Each fix has further narrowed the conditions for optimization.

It's time to give up on these optimization attempts and just run the cycle
detection logic every time fw_devlink tries to create a device link.

The specific bug report that triggered this fix involved a supplier fwnode
that never gets a device created for it. Instead, the supplier fwnode is
represented by the device that corresponds to an ancestor fwnode.

In this case, fw_devlink didn't do any cycle detection because the cycle
detection logic is only run when a device link is created between the
devices that correspond to the actual consumer and supplier fwnodes.

With this change, fw_devlink will run cycle detection logic even when
creating SYNC_STATE_ONLY proxy device links from a device that is an
ancestor of a consumer fwnode.

MIME-Version: 1.0

fwnode needs to be set for a device for fw_devlink to be able to
track/enforce its dependencies correctly. Without this, you'll see error
messages like this when the supplier has probed and tries to make sure
all its fwnode consumers are linked to it using device links:

Subject: [PATCH 1614/2948] serial: 8250: omap: Move pm_runtime_get_sync

Currently in omap_8250_shutdown, the dma->rx_running flag is
set to zero in omap_8250_rx_dma_flush. Next pm_runtime_get_sync
is called, which is a runtime resume call stack which can
re-set the flag. When the call omap_8250_shutdown returns, the
flag is expected to be UN-SET, but this is not the case. This
is causing issues the next time UART is re-opened and
omap_8250_rx_dma is called. Fix by moving pm_runtime_get_sync
before the omap_8250_rx_dma_flush.

 folios

All fuse requests use folios instead of pages for transferring data.
Remove pages from the requests and exclusively use folios.

No functional changes.

[SzM: rename back folio_descs -> descs, etc.]

Subject: [PATCH 1616/2948] f2fs: fix fiemap failure issue when page size is
 16KB

After enable 16K page size, an infinite loop may occur in
fiemap (fm_length=UINT64_MAX) on a file, such as the 16KB
scratch.img during the remount operation in Android.

The condition for whether fiemap continues to map is to check
whether the number of bytes corresponding to the next map.m_lblk
exceeds blks_to_bytes(inode,max_inode_blocks(inode)) if there are HOLE.
The latter does not take into account the maximum size of a file with 16KB
page size, so the loop cannot be jumped out.

The following is the fail trace:
When f2fs_map_blocks reaches map.m_lblk=3936, it needs to go to the
first direct node block, so the map is 3936 + 4090 = 8026,
The next map is the second direct node block, that is,
8026 + 4090 = 12116,
The next map is the first indirect node block, that is,
12116 + 4090 * 4090 = 16740216,
The next map is the second indirect node block, that is,
16740216 + 4090 * 4090 = 33468316,
The next map is the first double indirect node block, that is,
33468316 + 4090 * 4090 * 4090 = 68451397316
Since map.m_lblk represents the address of a block, which is 32
bits, truncation will occur, that is, 68451397316 becomes
4026887876, and the number of bytes corresponding to the block
number does not exceed blks_to_bytes(inode,max_inode_blocks(inode)),
so the loop will not be jumped out.
The next time, it will be considered that it should still be a
double indirect node block, that is,
4026887876 + 4090 * 4090 * 4090 = 72444816876, which will be
truncated to 3725340140, and the loop will not be jumped out.

Commit a6a010f5def5 ("f2fs: Restrict max filesize for 16K f2fs")
has set the maximum allowed file size to (U32_MAX + 1) * F2FS_BLKSIZE,
so max_file_blocks should be used here to limit it, that is,
maxbytes defined above. And the max_inode_blocks function is not
called by other functions except here, so cleanup it.

The root cause is a race condition in f2fs_stop_gc_thread() called from
different f2fs shutdown paths:

  [CPU0]                       [CPU1]
  ----------------------       -----------------------
  f2fs_stop_gc_thread          f2fs_stop_gc_thread
                                 gc_th = sbi->gc_thread
    gc_th = sbi->gc_thread
    kfree(gc_th)
    sbi->gc_thread = NULL
                                 < gc_th != NULL >
                                 kthread_stop(gc_th->f2fs_gc_task) //UAF

The commit c7f114d864ac ("f2fs: fix to avoid use-after-free in
f2fs_stop_gc_thread()") attempted to fix this issue by using a read
semaphore to prevent races between shutdown and remount threads, but
it fails to prevent all race conditions.

Fix it by converting to write lock of s_umount in f2fs_do_shutdown().

Subject: [PATCH 1618/2948] f2fs: fix to map blocks correctly for direct write

f2fs_map_blocks() supports to map continuous holes or preallocated
address, we should avoid setting F2FS_MAP_MAPPED for these cases
only, otherwise, it may fail f2fs_iomap_begin(), and make direct
write fallbacking to use buffered IO and flush, result in performance
regression.

Subject: [PATCH 1619/2948] f2fs: fix to avoid forcing direct write to use
 buffered IO on inline_data inode

Jinsu Lee reported a performance regression issue, after commit
5c8764f8679e ("f2fs: fix to force buffered IO on inline_data
inode"), we forced direct write to use buffered IO on inline_data
inode, it will cause performace regression due to memory copy
and data flush.

It's fine to not force direct write to use buffered IO, as it
can convert inline inode before committing direct write IO.

Subject: [PATCH 1620/2948] scripts: Remove export_report.pl

This script has been broken for 5 years with no user complaints.

It first had its .mod.c parser broken in commit a3d0cb04f7df ("modpost:
use __section in the output to *.mod.c"). Later, it had its object file
enumeration broken in commit f65a486821cf ("kbuild: change module.order
to list *.o instead of *.ko"). Both of these changes sat for years with
no reports.

Rather than reviving this script as we make further changes to `.mod.c`,
this patch gets rid of it because it is clearly unused.

"#interrupt-cells" is not valid without a corresponding "interrupt-map"

"#interrupt-cells".

This fixes a dtc interrupt_provider warning.

Sometimes it is useful to observe (and maybe modify) data coming from
an input device, but only do that if there are other users of such input
device. An example is touchpad switching functionality on Lenovo IdeaPad
Z570 where it is desirable to suppress events coming from the touchpad
if user toggles touchpad on/off button (on this laptop the firmware does
not stop the device).

Introduce notion of passive observers for input handlers to solve this
issue. An input handler marked as passive observer behaves exactly like
any other input handler or filter, but with one exception: it does not
open/start underlying input device when attaching to it.

This renames "Load" to "Open" and switches Ctrl-L to Ctrl-O for the default
platforms. This may break the workflow for those used to it, but will make it
actually work for everyone else like me who would just expect the default
behavior. Add some more standard shortcuts where available. If they replace
the existing shortcuts they would have the same value in my case.

Subject: [PATCH 1637/2948] kconfig: qconf: do not show goParent button in
 split view

When a menu is selected in the split view, the right pane displays the
goParent button, but it is never functional.

This is unnecessary, as you can select a menu from the menu tree in the
left pane.

Subject: [PATCH 1639/2948] kconfig: qconf: avoid unnecessary parentSelected()
 when ESC is pressed

When the ESC key is pressed, the parentSelected() signal is currently
emitted for singleMode, menuMode, and symbolMode.

However, parentSelected() signal is functional only for singleMode.

In menuMode, the signal is connected to the goBack() slot, but nothing
occurs because configList->rootEntry is always &rootmenu.

In symbolMode (in the right pane), the parentSelected() signal is not
connected to any slot.

This commit prevents the unnecessary emission of the parentSelected()
signal.

Commit c4f7398bee9c ("kconfig: qconf: make debug links work again")
changed prop->name to sym->name for this reference, but it missed to
change the tag "m" to "s".

This tag is not functional at all.

There is no need to use the regular expression to search for a symbol.
Calling sym_find() is simpler and faster.

The hyperlink always begins with the "s" tag, and there is no other
tag used. Remove it.

Subject: [PATCH 1648/2948] kexec/crash: no crash update when kexec in progress

The following errors are observed when kexec is done with SMT=off on
powerpc.

[  358.458385] Removing IBM Power 842 compression device
[  374.795734] kexec_core: Starting new kernel
[  374.795748] kexec: Waking offline cpu 1.
[  374.875695] crash hp: kexec_trylock() failed, elfcorehdr may be inaccurate
[  374.935833] kexec: Waking offline cpu 2.
[  375.015664] crash hp: kexec_trylock() failed, elfcorehdr may be inaccurate
snip..
[  375.515823] kexec: Waking offline cpu 6.
[  375.635667] crash hp: kexec_trylock() failed, elfcorehdr may be inaccurate
[  375.695836] kexec: Waking offline cpu 7.

To avoid kexec kernel boot failure on PowerPC, all the present CPUs that
are offline are brought online during kexec.  For more information, refer
to commit e8e5c2155b00 ("powerpc/kexec: Fix orphaned offline CPUs across
kexec").  Bringing the CPUs online triggers the crash hotplug handler,
crash_handle_hotplug_event(), to update the kdump image.  Since the system
is on the kexec kernel boot path and the kexec lock is held, the
crash_handle_hotplug_event() function fails to acquire the same lock to
update the kdump image, resulting in the error messages mentioned above.

To fix this, return from crash_handle_hotplug_event() without printing the
error message if kexec is in progress.

The same applies to the crash_check_hotplug_support() function.  Return 0
if kexec is in progress because kernel is not in a position to update the
kdump image.

Subject: [PATCH 1649/2948] kernel/watchdog: always restore
 watchdog_softlockup(,hardlockup)_user_enabled after proc show
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Otherwise when watchdog_enabled becomes 0,
watchdog_softlockup(,hardlockup)_user_enabled will changes to 0 after proc
show.

Steps to reproduce:

  step 1:
  # cat /proc/sys/kernel/*watchdog
  1
  1
  1

  | name                             | value
  |----------------------------------|--------------------------
  | watchdog_enabled                 | 1
  |----------------------------------|--------------------------
  | watchdog_hardlockup_user_enabled | 1
  |----------------------------------|--------------------------
  | watchdog_softlockup_user_enabled | 1
  |----------------------------------|--------------------------
  | watchdog_user_enabled            | 1
  |----------------------------------|--------------------------

  step 2:
  # echo 0 > /proc/sys/kernel/watchdog

  | name                             | value
  |----------------------------------|--------------------------
  | watchdog_enabled                 | 0
  |----------------------------------|--------------------------
  | watchdog_hardlockup_user_enabled | 1
  |----------------------------------|--------------------------
  | watchdog_softlockup_user_enabled | 1
  |----------------------------------|--------------------------
  | watchdog_user_enabled            | 0
  |----------------------------------|--------------------------

  step 3:
  # cat /proc/sys/kernel/*watchdog
  0
  0
  0

  | name                             | value
  |----------------------------------|--------------------------
  | watchdog_enabled                 | 0
  |----------------------------------|--------------------------
  | watchdog_hardlockup_user_enabled | 0
  |----------------------------------|--------------------------
  | watchdog_softlockup_user_enabled | 0
  |----------------------------------|--------------------------
  | watchdog_user_enabled            | 0
  |----------------------------------|--------------------------

  step 4:
  # echo 1 > /proc/sys/kernel/watchdog

  | name                             | value
  |----------------------------------|--------------------------
  | watchdog_enabled                 | 0
  |----------------------------------|--------------------------
  | watchdog_hardlockup_user_enabled | 0
  |----------------------------------|--------------------------
  | watchdog_softlockup_user_enabled | 0
  |----------------------------------|--------------------------
  | watchdog_user_enabled            | 0
  |----------------------------------|--------------------------

  step 5:
  # cat /proc/sys/kernel/*watchdog
  0
  0
  0

If we dont do "step 3", do "step 4" right after "step 2", it will be

  | name                             | value
  |----------------------------------|--------------------------
  | watchdog_enabled                 | 1
  |----------------------------------|--------------------------
  | watchdog_hardlockup_user_enabled | 1
  |----------------------------------|--------------------------
  | watchdog_softlockup_user_enabled | 1
  |----------------------------------|--------------------------
  | watchdog_user_enabled            | 1
  |----------------------------------|--------------------------

then everything works correctly.

So this patch fix "step 3"'s value into

| name                             | value
|----------------------------------|--------------------------
| watchdog_enabled                 | 0
|----------------------------------|--------------------------
| watchdog_hardlockup_user_enabled | 1
|----------------------------------|--------------------------
| watchdog_softlockup_user_enabled | 1
|----------------------------------|--------------------------
| watchdog_user_enabled            | 0
|----------------------------------|--------------------------

And still print 0 as before.

Subject: [PATCH 1650/2948] resource: replace open coded
 resource_intersection()

Patch series "resource: A couple of cleanups".

A couple of ad-hoc cleanups since there was a recent development of
the code in question. No functional changes intended.


This patch (of 2):

__region_intersects() uses open coded resource_intersection().  Replace it
with existing API which also make more clear what we are checking.

There are already a couple of places where we may replace a few lines of
code by calling a helper, which increases readability while deduplicating
the code.

Introduce is_type_match() helper and use it.

Subject: [PATCH 1653/2948] ipc/msg: replace one-element array with flexible
 array member

Replace the deprecated one-element array with a modern flexible array
member in the struct compat_msgbuf.

There are no binary differences after this conversion.

Subject: [PATCH 1654/2948] get rid of __get_task_comm()

Patch series "Improve the copy of task comm", v8.

Using {memcpy,strncpy,strcpy,kstrdup} to copy the task comm relies on the
length of task comm.  Changes in the task comm could result in a
destination string that is overflow.  Therefore, we should explicitly
ensure the destination string is always NUL-terminated, regardless of the
task comm.  This approach will facilitate future extensions to the task
comm.

As suggested by Linus [0], we can identify all relevant code with the
following git grep command:

  git grep 'memcpy.*->comm\>'
  git grep 'kstrdup.*->comm\>'
  git grep 'strncpy.*->comm\>'
  git grep 'strcpy.*->comm\>'

PATCH #2~#4:   memcpy
PATCH #5~#6:   kstrdup
PATCH #7:      strcpy

Please note that strncpy() is not included in this series as it is being
tracked by another effort. [1]


This patch (of 7):

We want to eliminate the use of __get_task_comm() for the following
reasons:

- The task_lock() is unnecessary
  Quoted from Linus [0]:
  : Since user space can randomly change their names anyway, using locking
  : was always wrong for readers (for writers it probably does make sense
  : to have some lock - although practically speaking nobody cares there
  : either, but at least for a writer some kind of race could have
  : long-term mixed results

Subject: [PATCH 1658/2948] mm/util: fix possible race condition in kstrdup()

In kstrdup(), it is critical to ensure that the dest string is always
NUL-terminated.  However, potential race condition can occur between a
writer and a reader.

Consider the following scenario involving task->comm:

    reader                    writer

  len = strlen(s) + 1;
                             strlcpy(tsk->comm, buf, sizeof(tsk->comm));
  memcpy(buf, s, len);

In this case, there is a race condition between the reader and the writer.
The reader calculates the length of the string `s` based on the old value
of task->comm.  However, during the memcpy(), the string `s` might be
updated by the writer to a new value of task->comm.

If the new task->comm is larger than the old one, the `buf` might not be
NUL-terminated.  This can lead to undefined behavior and potential
security vulnerabilities.

Let's fix it by explicitly adding a NUL terminator after the memcpy.  It
is worth noting that memcpy() is not atomic, so the new string can be
shorter when memcpy() already copied past the new NUL.

Subject: [PATCH 1666/2948] lib/crc16_kunit.c: add KUnit tests for crc16

Add Kunit tests for the kernel's implementation of the standard CRC-16
algorithm (<linux/crc16.h>).  The test data consists of 100
randomly-generated test cases, validated against a naive CRC-16
implementation.

This test follows roughly the same logic as lib/crc32test.c, but without
the performance measurements.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, cpuset is the only user of the union-find implementation.
Compiling union-find in all configurations unnecessarily increases the
code size when building the kernel without cgroup support.  Modify the
build system to compile union-find only when CONFIG_CPUSETS is enabled.

Use ERR_PTR_PCPU() when returning error pointer in the percpu address
space.  Use IS_ERR_PCPU() and PTR_ERR_PCPU() when returning the error
pointer from the percpu address space.  These macros add intermediate cast
to unsigned long when switching named address spaces.

The patch will avoid future build errors due to pointer address space
mismatch with enabled strict percpu address space checks.

Subject: [PATCH 1672/2948] ipc: fix memleak if msg_init_ns failed in
 create_ipc_ns

Percpu memory allocation may failed during create_ipc_ns however this
fail is not handled properly since ipc sysctls and mq sysctls is not
released properly. Fix this by release these two resource when failure.

Here is the kmemleak stack when percpu failed:

Subject: [PATCH 1673/2948] lib/list_sort: remove unnecessary header includes

Patch series "Remove unnecessary header includes from
{tools/}lib/list_sort.c".

Remove outdated and unnecessary header includes from lib/list_sort.c and
tools/lib/list_sort.c.  Additionally, update the hunk exceptions checked
by check_headers.sh to reflect these changes.


This patch (of 3):

After commit 043b3f7b6388 ("lib/list_sort: simplify and remove
MAX_LIST_LENGTH_BITS"), list_sort.c no longer uses ARRAY_SIZE() (which
required kernel.h and bug.h for BUILD_BUG_ON_ZERO via __must_be_array) or
memset() (which required string.h).  As these headers are no longer
needed, removes them.

There are no changes to the generated code, as confirmed by 'objdump -d'.
Additionally, 'wc -l' shows that the size of lib/.list_sort.o.cmd is
reduced from 259 lines to 101 lines.

Since lib/list_sort.c no longer requires ARRAY_SIZE() and memset(), the

tools/lib/list_sort.c also does not need to include these headers, so they

 user

Merge VERIFY_PERCPU_PTR() into non-CONFIG_SMP per_cpu_ptr() to make macro
similar to CONFIG_SMP per_cpu_ptr().  This will allow a follow-up patch to
refactor common code to a macro.

No functional changes, non-CONFIG_SMP per_cpu_ptr() was the only user of
VERIFY_PERCPU_PTR().

Introduce PERCPU_PTR() macro to cast the percpu pointer from the percpu
address space to a generic (kernel) address space.  Use it in
per_cpu_ptr() and related SHIFT_PERCPU_PTR() macros.

Also remove common knowledge from SHIFT_PERCPU_PTR() comment, "weird cast"
is just a standard way to inform sparse of a cast from the percpu address
space to a generic address space.

Subject: [PATCH 1679/2948] lib/min_heap: introduce non-inline versions of min
 heap API functions

Patch series "Enhance min heap API with non-inline functions and
optimizations", v2.

Add non-inline versions of the min heap API functions in lib/min_heap.c
and updates all users outside of kernel/events/core.c to use these
non-inline versions.  To mitigate the performance impact of indirect
function calls caused by the non-inline versions of the swap and compare
functions, a builtin swap has been introduced that swaps elements based on
their size.  Additionally, it micro-optimizes the efficiency of the min
heap by pre-scaling the counter, following the same approach as in
lib/sort.c.  Documentation for the min heap API has also been added to the
core-api section.


This patch (of 10):

All current min heap API functions are marked with '__always_inline'.
However, as the number of users increases, inlining these functions
everywhere leads to a increase in kernel size.

In performance-critical paths, such as when perf events are enabled and
min heap functions are called on every context switch, it is important to
retain the inline versions for optimal performance.  To balance this, the
original inline functions are kept, and additional non-inline versions of
the functions have been added in lib/min_heap.c.

Subject: [PATCH 1680/2948] lib min_heap: optimize min heap by prescaling
 counters for better performance

Improve the efficiency of the min heap by prescaling counters, eliminating
the need to repeatedly compute 'index * element_size' when accessing
elements.  By doing so, we avoid the overhead associated with
recalculating the byte offset for each heap operation.

However, with prescaling, the calculation for the parent element's
location is no longer as simple as '(i - 1) / 2'.  To address this, we
copy the parent function from 'lib/sort.c', which calculates the parent
offset in a branchless manner without using any division instructions.

This optimization should result in a more efficient heap implementation by
reducing the computational overhead of finding parent and child offsets.

Subject: [PATCH 1681/2948] lib min_heap: avoid indirect function call by
 providing default swap

The non-inline min heap API can result in an indirect function call to the
custom swap function.  This becomes particularly costly when
CONFIG_MITIGATION_RETPOLINE is enabled, as indirect function calls are
expensive in this case.

To address this, copy the code from lib/sort.c and provide a default
builtin swap implementation that performs element swaps based on the
element size.  This change allows most users to avoid the overhead of
indirect function calls, improving efficiency.

+Min Heap API
+============
+
+Introduction
+============
+
+The Min Heap API provides a set of functions and macros for managing min-heaps
+in the Linux kernel. A min-heap is a binary tree structure where the value of
+each node is less than or equal to the values of its children, ensuring that
+the smallest element is always at the root.
+
+This document provides a guide to the Min Heap API, detailing how to define and
+use min-heaps. Users should not directly call functions with **__min_heap_*()**
+prefixes, but should instead use the provided macro wrappers.
+
+In addition to the standard version of the functions, the API also includes a
+set of inline versions for performance-critical scenarios. These inline
+functions have the same names as their non-inline counterparts but include an
+**_inline** suffix. For example, **__min_heap_init_inline** and its
+corresponding macro wrapper **min_heap_init_inline**. The inline versions allow
+custom comparison and swap functions to be called directly, rather than through
+indirect function calls. This can significantly reduce overhead, especially
+when CONFIG_MITIGATION_RETPOLINE is enabled, as indirect function calls become
+more expensive. As with the non-inline versions, it is important to use the
+macro wrappers for inline functions instead of directly calling the functions
+themselves.
+
+Data Structures
+===============
+
+Min-Heap Definition
+-------------------
+
+The core data structure for representing a min-heap is defined using the
+**MIN_HEAP_PREALLOCATED** and **DEFINE_MIN_HEAP** macros. These macros allow
+you to define a min-heap with a preallocated buffer or dynamically allocated
+memory.
+
+Example:
+
+.. code-block:: c
+
+    #define MIN_HEAP_PREALLOCATED(_type, _name, _nr)
+    struct _name {
+        int nr;         /* Number of elements in the heap */
+        int size;       /* Maximum number of elements that can be held */
+        _type *data;    /* Pointer to the heap data */
+        _type preallocated[_nr];  /* Static preallocated array */
+    }
+
+    #define DEFINE_MIN_HEAP(_type, _name) MIN_HEAP_PREALLOCATED(_type, _name, 0)
+
+A typical heap structure will include a counter for the number of elements
+(`nr`), the maximum capacity of the heap (`size`), and a pointer to an array of
+elements (`data`). Optionally, you can specify a static array for preallocated
+heap storage using **MIN_HEAP_PREALLOCATED**.
+
+Min Heap Callbacks
+------------------
+
+The **struct min_heap_callbacks** provides customization options for ordering
+elements in the heap and swapping them. It contains two function pointers:
+
+.. code-block:: c
+
+    struct min_heap_callbacks {
+        bool (*less)(const void *lhs, const void *rhs, void *args);
+        void (*swp)(void *lhs, void *rhs, void *args);
+    };
+
+- **less** is the comparison function used to establish the order of elements.
+- **swp** is a function for swapping elements in the heap. If swp is set to
+  NULL, the default swap function will be used, which swaps the elements based on their size
+
+Macro Wrappers
+==============
+
+The following macro wrappers are provided for interacting with the heap in a
+user-friendly manner. Each macro corresponds to a function that operates on the
+heap, and they abstract away direct calls to internal functions.
+
+Each macro accepts various parameters that are detailed below.
+
+Heap Initialization
+--------------------
+
+.. code-block:: c
+
+    min_heap_init(heap, data, size);
+
+- **heap**: A pointer to the min-heap structure to be initialized.
+- **data**: A pointer to the buffer where the heap elements will be stored. If
+  `NULL`, the preallocated buffer within the heap structure will be used.
+- **size**: The maximum number of elements the heap can hold.
+
+This macro initializes the heap, setting its initial state. If `data` is
+`NULL`, the preallocated memory inside the heap structure will be used for
+storage. Otherwise, the user-provided buffer is used. The operation is **O(1)**.
+
+**Inline Version:** min_heap_init_inline(heap, data, size)
+
+Accessing the Top Element
+-------------------------
+
+.. code-block:: c
+
+    element = min_heap_peek(heap);
+
+- **heap**: A pointer to the min-heap from which to retrieve the smallest
+  element.
+
+This macro returns a pointer to the smallest element (the root) of the heap, or
+`NULL` if the heap is empty. The operation is **O(1)**.
+
+**Inline Version:** min_heap_peek_inline(heap)
+
+Heap Insertion
+--------------
+
+.. code-block:: c
+
+    success = min_heap_push(heap, element, callbacks, args);
+
+- **heap**: A pointer to the min-heap into which the element should be inserted.
+- **element**: A pointer to the element to be inserted into the heap.
+- **callbacks**: A pointer to a `struct min_heap_callbacks` providing the
+  `less` and `swp` functions.
+- **args**: Optional arguments passed to the `less` and `swp` functions.
+
+This macro inserts an element into the heap. It returns `true` if the insertion
+was successful and `false` if the heap is full. The operation is **O(log n)**.
+
+**Inline Version:** min_heap_push_inline(heap, element, callbacks, args)
+
+Heap Removal
+------------
+
+.. code-block:: c
+
+    success = min_heap_pop(heap, callbacks, args);
+
+- **heap**: A pointer to the min-heap from which to remove the smallest element.
+- **callbacks**: A pointer to a `struct min_heap_callbacks` providing the
+  `less` and `swp` functions.
+- **args**: Optional arguments passed to the `less` and `swp` functions.
+
+This macro removes the smallest element (the root) from the heap. It returns
+`true` if the element was successfully removed, or `false` if the heap is
+empty. The operation is **O(log n)**.
+
+**Inline Version:** min_heap_pop_inline(heap, callbacks, args)
+
+Heap Maintenance
+----------------
+
+You can use the following macros to maintain the heap's structure:
+
+.. code-block:: c
+
+    min_heap_sift_down(heap, pos, callbacks, args);
+
+- **heap**: A pointer to the min-heap.
+- **pos**: The index from which to start sifting down.
+- **callbacks**: A pointer to a `struct min_heap_callbacks` providing the
+  `less` and `swp` functions.
+- **args**: Optional arguments passed to the `less` and `swp` functions.
+
+This macro restores the heap property by moving the element at the specified
+index (`pos`) down the heap until it is in the correct position. The operation
+is **O(log n)**.
+
+**Inline Version:** min_heap_sift_down_inline(heap, pos, callbacks, args)
+
+.. code-block:: c
+
+    min_heap_sift_up(heap, idx, callbacks, args);
+
+- **heap**: A pointer to the min-heap.
+- **idx**: The index of the element to sift up.
+- **callbacks**: A pointer to a `struct min_heap_callbacks` providing the
+  `less` and `swp` functions.
+- **args**: Optional arguments passed to the `less` and `swp` functions.
+
+This macro restores the heap property by moving the element at the specified
+index (`idx`) up the heap. The operation is **O(log n)**.
+
+**Inline Version:** min_heap_sift_up_inline(heap, idx, callbacks, args)
+
+.. code-block:: c
+
+    min_heapify_all(heap, callbacks, args);
+
+- **heap**: A pointer to the min-heap.
+- **callbacks**: A pointer to a `struct min_heap_callbacks` providing the
+  `less` and `swp` functions.
+- **args**: Optional arguments passed to the `less` and `swp` functions.
+
+This macro ensures that the entire heap satisfies the heap property. It is
+called when the heap is built from scratch or after many modifications. The
+operation is **O(n)**.
+
+**Inline Version:** min_heapify_all_inline(heap, callbacks, args)
+
+Removing Specific Elements
+--------------------------
+
+.. code-block:: c
+
+    success = min_heap_del(heap, idx, callbacks, args);
+
+- **heap**: A pointer to the min-heap.
+- **idx**: The index of the element to delete.
+- **callbacks**: A pointer to a `struct min_heap_callbacks` providing the
+  `less` and `swp` functions.
+- **args**: Optional arguments passed to the `less` and `swp` functions.
+
+This macro removes an element at the specified index (`idx`) from the heap and
+restores the heap property. The operation is **O(log n)**.
+
+**Inline Version:** min_heap_del_inline(heap, idx, callbacks, args)
+
+Other Utilities
+===============
+
+- **min_heap_full(heap)**: Checks whether the heap is full.
+  Complexity: **O(1)**.
+
+.. code-block:: c
+
+    bool full = min_heap_full(heap);
+
+- `heap`: A pointer to the min-heap to check.
+
+This macro returns `true` if the heap is full, otherwise `false`.
+
+**Inline Version:** min_heap_full_inline(heap)
+
+- **min_heap_empty(heap)**: Checks whether the heap is empty.
+  Complexity: **O(1)**.
+
+.. code-block:: c
+
+    bool empty = min_heap_empty(heap);
+
+- `heap`: A pointer to the min-heap to check.

+**Inline Version:** min_heap_empty_inline(heap)
+
+Example Usage
+=============
+
+An example usage of the min-heap API would involve defining a heap structure,
+initializing it, and inserting and removing elements as needed.
+
+.. code-block:: c
+
+    #include <linux/min_heap.h>
+
+    int my_less_function(const void *lhs, const void *rhs, void *args) {
+        return (*(int *)lhs < *(int *)rhs);
+    }
+
+    struct min_heap_callbacks heap_cb = {
+        .less = my_less_function,    /* Comparison function for heap order */
+        .swp  = NULL,                /* Use default swap function */
+    };
+
+    void example_usage(void) {
+        /* Pre-populate the buffer with elements */
+        int buffer[5] = {5, 2, 8, 1, 3};
+        /* Declare a min-heap */
+        DEFINE_MIN_HEAP(int, my_heap);
+
+        /* Initialize the heap with preallocated buffer and size */
+        min_heap_init(&my_heap, buffer, 5);

Subject: [PATCH 1690/2948] nilfs2: convert segment buffer to be folio-based

Patch series "nilfs2: Finish folio conversion".

This series converts all remaining page structure references in nilfs2 to
folio-based, except for nilfs_copy_buffer function, which was converted to
use folios in advance for cross-fs page flags cleanup.

This prioritizes folio conversion, and does not include buffer head
reference reduction, nor does it support for block sizes larger than the
system page size.

The first eight patches in this series mainly convert each of the
nilfs2-specific metadata implementations to use folios.  The last four
patches, by Matthew Wilcox, eliminate aops writepage callbacks and convert
the remaining page structure references to folio-based.  This part
reflects some corrections to the patch series posted by Matthew.


This patch (of 12):

In the segment buffer (log buffer) implementation, two parts of the block
buffer, CRC calculation and bio preparation, are still page-based, so
convert them to folio-based.

 folio-based

In the common routines for metadata files, nilfs_mdt_insert_new_block(),
which inserts a new block buffer into the cache, is still page-based, and
there are two places where bh_offset() is used.  Convert these to
page-based.

Subject: [PATCH 1692/2948] nilfs2: convert segment usage file to be
 folio-based

For the sufile, which is a metadata file that holds information about
managing segments, convert the page-based implementation to a folio-based
implementation.

kmap_local_page() is changed to use kmap_local_folio(), and where offsets
within a page are calculated using bh_offset(), are replaced with
calculations using offset_in_folio() with an additional helper function
nilfs_sufile_segment_usage_offset().

Subject: [PATCH 1693/2948] nilfs2: convert persistent object allocator to be
 folio-based

Regarding the persistent oject allocator, a common mechanism for
allocating objects in metadata files such as inodes and DAT entries,
convert the page-based implementation to a folio-based implementation.

In this conversion, helper functions nilfs_palloc_group_desc_offset() and
nilfs_palloc_bitmap_offset() are added and used to calculate the byte
offset within a folio of a group descriptor structure and bitmap,
respectively, to replace kmap_local_page with kmap_local_folio.

In addition, a helper function called nilfs_palloc_entry_offset() is
provided to facilitate common calculation of the byte offset within a
folio of metadata file entries managed in the persistent object allocator
format.

Subject: [PATCH 1697/2948] nilfs2: convert checkpoint file to be folio-based

Regarding the cpfile, a metadata file that manages checkpoints, convert
the page-based implementation to a folio-based implementation.

This change involves some helper functions to calculate byte offsets on
folios and removing a few helper functions that are no longer needed.

Subject: [PATCH 1698/2948] nilfs2: remove nilfs_writepage

Since nilfs2 has a ->writepages operation already, ->writepage is only
called by the migration code.  If we add a ->migrate_folio operation, it
won't even be used for that and so it can be deleted.

Use memcpy_to_folio() instead of open-coding it, and use offset_in_folio()
in case anybody wants to use nilfs2 on a device with large blocks.

page in nilfs2.

Subject: [PATCH 1702/2948] checkpatch: always parse orig_commit in fixes tag
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Do not require the presence of `$balanced_parens` to get the commit SHA;
this allows a `Fixes: deadbeef` tag to get a correct suggestion rather
than a suggestion containing a reference to HEAD.

Given this patch:

: From: Tamir Duberstein <tamird@gmail.com>
: Subject: Test patch
: Date: Fri, 25 Oct 2024 19:30:51 -0400
:
: This is a test patch.
:
: Fixes: bd17e036b495
: Signed-off-by: Tamir Duberstein <tamird@gmail.com>
: --- /dev/null
: +++ b/new-file
: @@ -0,0 +1 @@
: +Test.


Before:

WARNING: Please use correct Fixes: style 'Fixes: <12 chars of sha1> ("<title line>")' - ie: 'Fixes: c10a7d25e68f ("Test patch")'

After:

WARNING: Please use correct Fixes: style 'Fixes: <12 chars of sha1> ("<title line>")' - ie: 'Fixes: bd17e036b495 ("checkpatch: warn for non-standard fixes tag style")'



The prior behavior incorrectly suggested the patch's own SHA and title
line rather than the referenced commit's.  This fixes that.

Ironically this:

Fixes: bd17e036b495 ("checkpatch: warn for non-standard fixes tag style")

 event's arguments

trace__fprintf_tp_fields may not print any tracepoint arguments. E.g., if the
argument values are all zero. Previously, this would result in a totally
uninitialized buffer being passed to fprintf, which could lead to garbage on the
console. Fix the problem by passing the number of initialized bytes fprintf.

Subject: [PATCH 1709/2948] usb: xhci: Fix sum_trb_lengths()

This function is supposed to sum the lengths of all transfer TRBs in
a TD up to a point, but it starts summing at the current dequeue since
it only ever gets called on the first pending TD.

This won't work when there are cancelled TDs at the beginning of the
ring. The function tries to exclude No-Ops from the count, but not all
cancelled TDs are No-Op'ed - not those the HW stopped on.

The absolutely obvious fix is to start counting at the TD's first TRB.
And remove the now-useless 'ring' parameter, and 'xhci' too.

Subject: [PATCH 1711/2948] xhci: show DMA address of TRB when tracing TRBs

The DMA address of a queued TRB is essential when looking at traces as
both transfer events and command completion events refer to the command
or transfer based on its DMA address.

Previously the TRB address was figured out from xhci_inc_enq and
xhci_inc_deq trace entries seen after queuing or handlong a TRB.

Now that DMA address is shown in TRB tracing we can get rid of most of the
xhci_inc_enq and xhci_inc_deq traces thus decreasing trace size.

Subject: [PATCH 1712/2948] xhci: Don't trace ring at every enqueue or dequeue
 increase

Don't trace ring pointers every time driver increases enqueue pointer
after queuing a TRB, or dequeue pointer after handling an event.

These xhci_inc_deq: and xhci_inc_enq: trace entries fill up the trace and
provides little useful info now that the TRB DMA address is printed with
the TRB itself.

Only trace ring during xhci_inc_enq() and xhci_inc_deq() in case we move
to a new ring segment.

Also don't show both segment and TRB addess in trace.
Segment is just TRB with 0xfff masked off.

Subject: [PATCH 1716/2948] usb: xhci: introduce macro for ring segment list
 iteration

Add macro to streamline and standardize the iteration over ring
segment list.

xhci_for_each_ring_seg(): Iterates over the entire ring segment list.

The xhci_free_segments_for_ring() function's while loop has not been
updated to use the new macro. This function has some underlying issues,
and as a result, it will be handled separately in a future patch.

Subject: [PATCH 1717/2948] usb: xhci: remove option to change a default ring's
 TRB cycle bit

The TRB cycle bit indicates TRB ownership by the Host Controller (HC) or
Host Controller Driver (HCD). New rings are initialized with 'cycle_state'
equal to one, and all its TRBs' cycle bits are set to zero. When handling
ring expansion, set the source ring cycle bits to the same value as the
destination ring.

Move the cycle bit setting from xhci_segment_alloc() to xhci_link_rings(),
and remove the 'cycle_state' argument from xhci_initialize_ring_info().
The xhci_segment_alloc() function uses kzalloc_node() to allocate segments,
ensuring that all TRB cycle bits are initialized to zero.

Subject: [PATCH 1718/2948] usb: xhci: adjust xhci_alloc_segments_for_ring()
 arguments

The function xhci_alloc_segments_for_ring() currently takes 7 arguments,
5 of which are components of the 'xhci_ring' struct. Refactor the function
to accept a pointer to the 'xhci_ring' struct instead of passing these
components separately.

The change reduces the number of arguments, making the function signature
cleaner and easier to understand.

Subject: [PATCH 1719/2948] usb: xhci: rework xhci_free_segments_for_ring()

The segment list is only relevant within the context of the ring.
Thus, it is more logical to pass the ring itself when freeing all segments
from a ring, rather than passing the ring list.

Rename the function to "xhci_ring_segments_free" to align with the naming
convention of xhci_segment_free().

To make the freeing process more intuitive, free segments sequentially
from start to end (i.e., 0, 1, 2, 3, ...) instead of freeing the first
segment last (i.e., 1, 2, 3, ... 0).

 and destination rings

Refactor the xhci_link_rings() function to accept two rings: a source ring
and a destination ring. Previously, the function accepted a ring and a
segment list as arguments, now the function splices the source ring segment
list into the destination ring. This new approach reduces the number of
arguments and simplifies the code, making it easier to follow.

Subject: [PATCH 1721/2948] usb: xhci: rework xhci_link_segments()

Prepare for splitting ring segments allocation and initialization by
reworking the xhci_link_segments() function. Segment linking and ring type
checks are moved out of xhci_link_segments(), and the function is renamed
to "xhci_set_link_trb()".

The goal is to keep ring linking within xhci_alloc_segments_for_ring() and
move initialization into a separate function.

Additionally, reorder and simplify xhci_set_link_trb() for better
readability.

Subject: [PATCH 1722/2948] usb: xhci: add xhci_initialize_ring_segments()

A ring consists of a list of segments, each containing a specific number of
TRBs. The xhci driver allocates and initializes ring segments and TRBs in
the same functions. This combined allocation and initialization process
leads to an issue where, after hibernation (S4 state), the xhci driver
frees all its memory and re-creates the rings, segments, and TRBs from
scratch.

Move all default ring segment initialization into function
xhci_initialize_ring_segments(). This function can be called to
reinitialize a ring without freeing and reallocating it.

Since xhci_alloc_segments_for_ring() no longer initializes segment TRBs,
xhci_initialize_ring_segments() is added to xhci_ring_expansion(). This
results in the last segment of the source ring having the 'LINK_TOGGLE'
bit set. Therefore, if the last source ring segment is not the last in
the destination ring, the 'LINK_TOGGLE' bit must be cleared.

Subject: [PATCH 1724/2948] xhci: Don't issue Reset Device command to Etron
 xHCI host

Sometimes the hub driver does not recognize the USB device connected
to the external USB2.0 hub when the system resumes from S4.

After the SetPortFeature(PORT_RESET) request is completed, the hub
driver calls the HCD reset_device callback, which will issue a Reset
Device command and free all structures associated with endpoints
that were disabled.

This happens when the xHCI driver issue a Reset Device command to
inform the Etron xHCI host that the USB device associated with a
device slot has been reset. Seems that the Etron xHCI host can not
perform this command correctly, affecting the USB device.

To work around this, the xHCI driver should obtain a new device slot
with reference to commit 651aaf36a7d7 ("usb: xhci: Handle USB transaction
error on address command"), which is another way to inform the Etron
xHCI host that the USB device has been reset.

Add a new XHCI_ETRON_HOST quirk flag to invoke the workaround in
xhci_discover_or_reset_device().

Subject: [PATCH 1725/2948] xhci: Fix control transfer error on Etron xHCI host

Performing a stability stress test on a USB3.0 2.5G ethernet adapter
results in errors like this:

[   91.441469] r8152 2-3:1.0 eth3: get_registers -71
[   91.458659] r8152 2-3:1.0 eth3: get_registers -71
[   91.475911] r8152 2-3:1.0 eth3: get_registers -71
[   91.493203] r8152 2-3:1.0 eth3: get_registers -71
[   91.510421] r8152 2-3:1.0 eth3: get_registers -71

The r8152 driver will periodically issue lots of control-IN requests
to access the status of ethernet adapter hardware registers during
the test.

This happens when the xHCI driver enqueue a control TD (which cross
over the Link TRB between two ring segments, as shown) in the endpoint
zero's transfer ring. Seems the Etron xHCI host can not perform this
TD correctly, causing the USB transfer error occurred, maybe the upper
driver retry that control-IN request can solve problem, but not all
drivers do this.

|     |
-------
| TRB | Setup Stage
-------
| TRB | Link
-------
-------
| TRB | Data Stage
-------
| TRB | Status Stage
-------
|     |

To work around this, the xHCI driver should enqueue a No Op TRB if
next available TRB is the Link TRB in the ring segment, this can
prevent the Setup and Data Stage TRB to be breaked by the Link TRB.

Check if the XHCI_ETRON_HOST quirk flag is set before invoking the
workaround in xhci_queue_ctrl_tx().

errors like this:

Seems that Etorn xHCI host can not perform Soft Retry correctly, apply

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The definitions of vendor IDs follow the pattern PCI_VENDOR_ID_#vendor,
while device IDs — PCI_DEVICE_ID_#vendor_#device.

Update the ETRON device IDs to follow the above mentioned pattern.

Subject: [PATCH 1729/2948] usb: xhci: simplify TDs start and end naming scheme
 in struct 'xhci_td'

Old names:
 * start_seg - last_trb_seg
 * first_trb - last_trb

New names:
 * start_seg - end_seg
 * start_trb - end_trb

A Transfer Descriptor (TD) in the xhci driver is a data structure that
represents a single transaction to be performed by the USB host controller.
This transaction is defined by TRBs from 'start_trb' in 'start_seg' to
'end_trb' in 'end_seg'.

The terms "start" and "end" were chosen  over "first" and "last" for ease
of searching within the codebase. The ring structure uses 'first_seg' and
'last_seg', while the TD structure uses 'start_seg' and 'end_seg'.

Subject: [PATCH 1730/2948] usb: xhci: move link TRB quirk to xhci_gen_setup()

This quirk is old and seldom seen, as a result the trace is changed
to debug message and only printed when the quirk is set.

Move it into xhci_gen_setup() where the majority of quirks are set.

Subject: [PATCH 1731/2948] usb: xhci: request MSI/-X according to requested
 amount

Variable 'max_interrupters' contains the maximum supported interrupters
or the maximum interrupters the user has requested. Thus, it should be
used instead of HCS_MAX_INTRS().

User set 'max_interrupters' value is validated in xhci_gen_setup(),
otherwise 'max_interrupters' value is 'HCS_MAX_INTRS(xhci->hcs_params1)'.

Subject: [PATCH 1732/2948] usb: xhci: improve xhci_clear_command_ring()

Remove redundant TRB cycle reset, the TRB cycle is already set to zero by
the preceding memset(), making the explicit reset unnecessary.

Clarify ring loop start point. Change the loop start from the dequeue
segment to the start segment. Both approaches achieve the same result,
but starting from the start segment makes it clearer that the entire ring
is being zeroed out.

Subject: [PATCH 1734/2948] usb: xhci: refactor xhci_td_cleanup() to return
 void

The function is modified to return 'void' instead of an integer since it
invariably returns '0'. Additionally, multiple functions which only
return xhci_td_cleanup() are also refactored to return void.

This change eliminates the need for callers to handle a return value that
does not convey meaningful information and improve code readability, as it
becomes immediately clear that the function does not produce a significant
output.

Subject: [PATCH 1737/2948] usb: xhci: Limit Stop Endpoint retries

Some host controllers fail to atomically transition an endpoint to the
Running state on a doorbell ring and enter a hidden "Restarting" state,
which looks very much like Stopped, with the important difference that
it will spontaneously transition to Running anytime soon.

A Stop Endpoint command queued in the Restarting state typically fails
with Context State Error and the completion handler sees the Endpoint
Context State as either still Stopped or already Running. Even a case
of Halted was observed, when an error occurred right after the restart.

The Halted state is already recovered from by resetting the endpoint.
The Running state is handled by retrying Stop Endpoint.

The Stopped state was recognized as a problem on NEC controllers and
worked around also by retrying, because the endpoint soon restarts and
then stops for good. But there is a risk: the command may fail if the
endpoint is "stopped for good" already, and retries will fail forever.

The possibility of this was not realized at the time, but a number of
cases were discovered later and reproduced. Some proved difficult to
deal with, and it is outright impossible to predict if an endpoint may
fail to ever start at all due to a hardware bug. One such bug (albeit
on ASM3142, not on NEC) was found to be reliably triggered simply by
toggling an AX88179 NIC up/down in a tight loop for a few seconds.

An endless retries storm is quite nasty. Besides putting needless load
on the xHC and CPU, it causes URBs never to be given back, paralyzing
the device and connection/disconnection logic for the whole bus if the
device is unplugged. User processes waiting for URBs become unkillable,
drivers and kworker threads lock up and xhci_hcd cannot be reloaded.

For peace of mind, impose a timeout on Stop Endpoint retries in this
case. If they don't succeed in 100ms, consider the endpoint stopped
permanently for some reason and just give back the unlinked URBs. This
failure case is rare already and work is under way to make it rarer.

Start this work today by also handling one simple case of race with
Reset Endpoint, because it costs just two lines to implement.

Subject: [PATCH 1738/2948] usb: xhci: Fix TD invalidation under pending Set TR
 Dequeue

xhci_invalidate_cancelled_tds() may not work correctly if the hardware
is modifying endpoint or stream contexts at the same time by executing
a Set TR Dequeue command. And even if it worked, it would be unable to
queue Set TR Dequeue for the next stream, failing to clear xHC cache.

On stream endpoints, a chain of Set TR Dequeue commands may take some
time to execute and we may want to cancel more TDs during this time.
Currently this leads to Stop Endpoint completion handler calling this
function without testing for SET_DEQ_PENDING, which will trigger the
aforementioned problems when it happens.

On all endpoints, a halt condition causes Reset Endpoint to be queued
and an error status given to the class driver, which may unlink more
URBs in response. Stop Endpoint is queued and its handler may execute
concurrently with Set TR Dequeue queued by Reset Endpoint handler.

(Reset Endpoint handler calls this function too, but there seems to
be no possibility of it running concurrently with Set TR Dequeue).

Fix xhci_invalidate_cancelled_tds() to work correctly under a pending
Set TR Dequeue. Bail out of the function when SET_DEQ_PENDING is set,
then make the completion handler call the function again and also call
xhci_giveback_invalidated_tds(), which needs to be called next.

This seems to fix another potential bug, where the handler would call
xhci_invalidate_cancelled_tds(), which may clear some deferred TDs if
a sanity check fails, and the TDs wouldn't be given back promptly.

Said sanity check seems to be wrong and prone to false positives when
the endpoint halts, but fixing it is beyond the scope of this change,
besides ensuring that cleared TDs are given back properly.

Subject: [PATCH 1739/2948] usb: xhci: Avoid queuing redundant Stop Endpoint
 commands

Stop Endpoint command on an already stopped endpoint fails and may be
misinterpreted as a known hardware bug by the completion handler. This
results in an unnecessary delay with repeated retries of the command.

Avoid queuing this command when endpoint state flags indicate that it's
stopped or halted and the command will fail. If commands are pending on
the endpoint, their completion handlers will process cancelled TDs so
it's done. In case of waiting for external operations like clearing TT
buffer, the endpoint is stopped and cancelled TDs can be processed now.

This eliminates practically all unnecessary retries because an endpoint
with pending URBs is maintained in Running state by the driver, unless
aforementioned commands or other operations are pending on it. This is
guaranteed by xhci_ring_ep_doorbell() and by the fact that it is called
every time any of those operations completes.

The only known exceptions are hardware bugs (the endpoint never starts
at all) and Stream Protocol errors not associated with any TRB, which
cause an endpoint reset not followed by restart. Sounds like a bug.

Generally, these retries are only expected to happen when the endpoint
fails to start for unknown/no reason, which is a worse problem itself,
and fixing the bug eliminates the retries too.

All cases were tested and found to work as expected. SET_DEQ_PENDING
was produced by patching uvcvideo to unlink URBs in 100us intervals,
which then runs into this case very often. EP_HALTED was produced by
restarting 'cat /dev/ttyUSB0' on a serial dongle with broken cable.
EP_CLEARING_TT by the same, with the dongle on an external hub.

Subject: [PATCH 1740/2948] kbuild: simplify rustfmt target

There is no need to prune the rust/alloc directory because it was
removed by commit 9d0441bab775 ("rust: alloc: remove our fork of the
`alloc` crate").

There is no need to prune the rust/test directory because no '*.rs'
files are generated within it.

To avoid forking the 'grep -Fv generated' process, filter out generated
files using the option, ! -name '*generated*'.

Now that the '-path ... -prune' option is no longer used, there is no
need to use the absolute path. Searching in $(srctree), which can be
a relative path, is sufficient.

The comment mentions the use case where $(srctree) is '..', that is,
$(objtree) is a sub-directory of $(srctree). In this scenario, all
'*.rs' files under $(objtree) are generated files and filters out by
the '*generated*' pattern.

Add $(RCS_FIND_IGNORE) as a shortcut. Although I do not believe '*.rs'
files would exist under the .git directory, there is no need for the
'find' command to traverse it.

Subject: [PATCH 1741/2948] kbuild: Add AutoFDO support for Clang build

Add the build support for using Clang's AutoFDO. Building the kernel
with AutoFDO does not reduce the optimization level from the
compiler. AutoFDO uses hardware sampling to gather information about
the frequency of execution of different code paths within a binary.
This information is then used to guide the compiler's optimization
decisions, resulting in a more efficient binary. Experiments
showed that the kernel can improve up to 10% in latency.

The support requires a Clang compiler after LLVM 17. This submission
is limited to x86 platforms that support PMU features like LBR on
Intel machines and AMD Zen3 BRS. Support for SPE on ARM 1,
 and BRBE on ARM 1 is part of planned future work.

Here is an example workflow for AutoFDO kernel:

1) Build the kernel on the host machine with LLVM enabled, for example,
       $ make menuconfig LLVM=1
    Turn on AutoFDO build config:
      CONFIG_AUTOFDO_CLANG=y
    With a configuration that has LLVM enabled, use the following
    command:
       scripts/config -e AUTOFDO_CLANG
    After getting the config, build with
      $ make LLVM=1

2) Install the kernel on the test machine.

3) Run the load tests. The '-c' option in perf specifies the sample
   event period. We suggest     using a suitable prime number,
   like 500009, for this purpose.
   For Intel platforms:
      $ perf record -e BR_INST_RETIRED.NEAR_TAKEN:k -a -N -b -c <count> \
        -o <perf_file> -- <loadtest>
   For AMD platforms:
      The supported system are: Zen3 with BRS, or Zen4 with amd_lbr_v2
     For Zen3:
      $ cat proc/cpuinfo | grep " brs"
      For Zen4:
      $ cat proc/cpuinfo | grep amd_lbr_v2
      $ perf record --pfm-events RETIRED_TAKEN_BRANCH_INSTRUCTIONS:k -a \
        -N -b -c <count> -o <perf_file> -- <loadtest>

4) (Optional) Download the raw perf file to the host machine.

5) To generate an AutoFDO profile, two offline tools are available:
   create_llvm_prof and llvm_profgen. The create_llvm_prof tool is part
   of the AutoFDO project and can be found on GitHub
   (https://github.com/google/autofdo), version v0.30.1 or later. The
   llvm_profgen tool is included in the LLVM compiler itself. It's
   important to note that the version of llvm_profgen doesn't need to
   match the version of Clang. It needs to be the LLVM 19 release or
   later, or from the LLVM trunk.
      $ llvm-profgen --kernel --binary=<vmlinux> --perfdata=<perf_file> \
        -o <profile_file>
   or
      $ create_llvm_prof --binary=<vmlinux> --profile=<perf_file> \
        --format=extbinary --out=<profile_file>

   Note that multiple AutoFDO profile files can be merged into one via:

+===================================
+Using AutoFDO with the Linux kernel
+===================================
+
+This enables AutoFDO build support for the kernel when using
+the Clang compiler. AutoFDO (Auto-Feedback-Directed Optimization)
+is a type of profile-guided optimization (PGO) used to enhance the
+performance of binary executables. It gathers information about the
+frequency of execution of various code paths within a binary using
+hardware sampling. This data is then used to guide the compiler's
+optimization decisions, resulting in a more efficient binary. AutoFDO
+is a powerful optimization technique, and data indicates that it can
+significantly improve kernel performance. It's especially beneficial
+for workloads affected by front-end stalls.
+
+For AutoFDO builds, unlike non-FDO builds, the user must supply a
+profile. Acquiring an AutoFDO profile can be done in several ways.
+AutoFDO profiles are created by converting hardware sampling using
+the "perf" tool. It is crucial that the workload used to create these
+perf files is representative; they must exhibit runtime
+characteristics similar to the workloads that are intended to be
+optimized. Failure to do so will result in the compiler optimizing
+for the wrong objective.
+
+The AutoFDO profile often encapsulates the program's behavior. If the
+performance-critical codes are architecture-independent, the profile
+can be applied across platforms to achieve performance gains. For
+instance, using the profile generated on Intel architecture to build
+a kernel for AMD architecture can also yield performance improvements.
+
+There are two methods for acquiring a representative profile:
+(1) Sample real workloads using a production environment.
+(2) Generate the profile using a representative load test.
+When enabling the AutoFDO build configuration without providing an
+AutoFDO profile, the compiler only modifies the dwarf information in
+the kernel without impacting runtime performance. It's advisable to
+use a kernel binary built with the same AutoFDO configuration to
+collect the perf profile. While it's possible to use a kernel built
+with different options, it may result in inferior performance.
+
+One can collect profiles using AutoFDO build for the previous kernel.
+AutoFDO employs relative line numbers to match the profiles, offering
+some tolerance for source changes. This mode is commonly used in a
+production environment for profile collection.
+
+In a profile collection based on a load test, the AutoFDO collection
+process consists of the following steps:
+
+#. Initial build: The kernel is built with AutoFDO options
+   without a profile.
+
+#. Profiling: The above kernel is then run with a representative
+   workload to gather execution frequency data. This data is
+   collected using hardware sampling, via perf. AutoFDO is most
+   effective on platforms supporting advanced PMU features like
+   LBR on Intel machines.
+
+#. AutoFDO profile generation: Perf output file is converted to
+   the AutoFDO profile via offline tools.
+
+The support requires a Clang compiler LLVM 17 or later.
+
+Preparation
+===========
+
+Configure the kernel with::
+
+   CONFIG_AUTOFDO_CLANG=y
+
+Customization
+=============
+
+The default CONFIG_AUTOFDO_CLANG setting covers kernel space objects for
+AutoFDO builds. One can, however, enable or disable AutoFDO build for
+individual files and directories by adding a line similar to the following
+to the respective kernel Makefile:
+
+- For enabling a single file (e.g. foo.o) ::
+
+   AUTOFDO_PROFILE_foo.o := y
+
+- For enabling all files in one directory ::
+
+   AUTOFDO_PROFILE := y
+
+- For disabling one file ::
+
+   AUTOFDO_PROFILE_foo.o := n
+
+- For disabling all files in one directory ::
+
+   AUTOFDO_PROFILE := n
+
+Workflow
+========
+
+Here is an example workflow for AutoFDO kernel:
+
+1)  Build the kernel on the host machine with LLVM enabled,
+    for example, ::
+
+      $ make menuconfig LLVM=1
+
+    Turn on AutoFDO build config::
+
+      CONFIG_AUTOFDO_CLANG=y
+
+    With a configuration that with LLVM enabled, use the following command::
+
+      $ scripts/config -e AUTOFDO_CLANG
+
+    After getting the config, build with ::
+
+      $ make LLVM=1
+
+2) Install the kernel on the test machine.
+
+3) Run the load tests. The '-c' option in perf specifies the sample
+   event period. We suggest using a suitable prime number, like 500009,
+   for this purpose.
+
+   - For Intel platforms::
+
+      $ perf record -e BR_INST_RETIRED.NEAR_TAKEN:k -a -N -b -c <count> -o <perf_file> -- <loadtest>
+
+   - For AMD platforms:
+
+     The supported systems are: Zen3 with BRS, or Zen4 with amd_lbr_v2. To check,
+
+     For Zen3::
+
+      $ cat proc/cpuinfo | grep " brs"
+
+     For Zen4::
+
+      $ cat proc/cpuinfo | grep amd_lbr_v2
+
+     The following command generated the perf data file::
+
+      $ perf record --pfm-events RETIRED_TAKEN_BRANCH_INSTRUCTIONS:k -a -N -b -c <count> -o <perf_file> -- <loadtest>
+
+4) (Optional) Download the raw perf file to the host machine.
+
+5) To generate an AutoFDO profile, two offline tools are available:
+   create_llvm_prof and llvm_profgen. The create_llvm_prof tool is part
+   of the AutoFDO project and can be found on GitHub
+   (https://github.com/google/autofdo), version v0.30.1 or later.
+   The llvm_profgen tool is included in the LLVM compiler itself. It's
+   important to note that the version of llvm_profgen doesn't need to match
+   the version of Clang. It needs to be the LLVM 19 release of Clang
+   or later, or just from the LLVM trunk. ::
+
+      $ llvm-profgen --kernel --binary=<vmlinux> --perfdata=<perf_file> -o <profile_file>
+
+   or ::
+
+      $ create_llvm_prof --binary=<vmlinux> --profile=<perf_file> --format=extbinary --out=<profile_file>
+
+   Note that multiple AutoFDO profile files can be merged into one via::
+
+      $ llvm-profdata merge -o <profile_file> <profile_1> <profile_2> ... <profile_n>
+
+6) Rebuild the kernel using the AutoFDO profile file with the same config as step 1,
+   (Note CONFIG_AUTOFDO_CLANG needs to be enabled)::
+
+      $ make LLVM=1 CLANG_AUTOFDO_PROFILE=<profile_file>

Subject: [PATCH 1742/2948] objtool: Fix unreachable instruction warnings for
 weak functions

In the presence of both weak and strong function definitions, the
linker drops the weak symbol in favor of a strong symbol, but
leaves the code in place. Code in ignore_unreachable_insn() has
some heuristics to suppress the warning, but it does not work when
-ffunction-sections is enabled.

Suppose function foo has both strong and weak definitions.
Case 1: The strong definition has an annotated section name,
like .init.text. Only the weak definition will be placed into
.text.foo. But since the section has no symbols, there will be no
"hole" in the section.

Case 2: Both sections are without an annotated section name.
Both will be placed into .text.foo section, but there will be only one
symbol (the strong one). If the weak code is before the strong code,
there is no "hole" as it fails to find the right-most symbol before
the offset.

The fix is to use the first node to compute the hole if hole.sym
is empty. If there is no symbol in the section, the first node
will be NULL, in which case, -1 is returned to skip the whole
section.

Add support for restricting the port's link width by specifying
the num-lanes devicetree property in the PCIe node.

The setting is done in the GEN_SETTINGS register (in the driver
named as PCIE_SETTING_REG), where each set bit in [11:8] activates
a set of lanes (from bits 11 to 8 respectively, x16/x8/x4/x2).

Subject: [PATCH 1746/2948] resource: avoid unnecessary resource tree walking
 in __region_intersects()

Currently, if __region_intersects() finds any overlapped but unmatched
resource, it walks the descendant resource tree to check for overlapped
and matched descendant resources using for_each_resource().  However, in
current kernel, for_each_resource() iterates not only the descendant tree,
but also subsequent sibling trees in certain scenarios.  While this
doesn't introduce bugs, it makes code hard to be understood and
potentially inefficient.

So, the patch revises next_resource() and for_each_resource() and makes
for_each_resource() traverse the subtree under the specified subtree root
only.  Test shows that this avoids unnecessary resource tree walking in
__region_intersects().

For the example resource tree as follows,

  X
  |
  A----D----E
  |
  B--C

if 'A' is the overlapped but unmatched resource, original kernel
iterates 'B', 'C', 'D', 'E' when it walks the descendant tree.  While
the patched kernel iterates only 'B', 'C'.

Thanks David Hildenbrand for providing a good resource tree example.

./fs/proc/kcore.c:614:26-30: ERROR: invalid reference to the index variable of the iterator on line 499

Replacing `struct kcore_list *iter' with `struct kcore_list *tmp' doesn't change the
scope and the functionality is the same and coccinelle seems happy.

NOTE: There was an issue with using `struct kcore_list *pos' as the nested iterator.
      The build did not work!

Subject: [PATCH 1749/2948] PCI: imx6: Fix suspend/resume support on i.MX6QDL
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The suspend/resume functionality is currently broken on the i.MX6QDL
platform, as documented in the NXP errata (ERR005723):

  https://www.nxp.com/docs/en/errata/IMX6DQCE.pdf

This patch addresses the issue by sharing most of the suspend/resume
sequences used by other i.MX devices, while avoiding modifications to
critical registers that disrupt the PCIe functionality. It targets the
same problem as the following downstream commit:

  https://github.com/nxp-imx/linux-imx/commit/4e92355e1f79d225ea842511fcfd42b343b32995

Unlike the downstream commit, this patch also resets the connected PCIe
device if possible. Without this reset, certain drivers, such as ath10k
or iwlwifi, will crash on resume. The device reset is also done by the
driver on other i.MX platforms, making this patch consistent with
existing practices.

Upon resuming, the kernel will hang and display an error. Here's an
example of the error encountered with the ath10k driver:

  ath10k_pci 0000:01:00.0: Unable to change power state from D3hot to D0, device inaccessible
  Unhandled fault: imprecise external abort (0x1406) at 0x0106f944

Without this patch, suspend/resume will fail on i.MX6QDL devices if a
PCIe device is connected.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The remapped PCIe Root Port and the child device have PM L1 Substates
capability, but they are disabled originally.

Here is a failed example on ASUS B1400CEAE:

  Capabilities: [900 v1] L1 PM Substates
        L1SubCap: PCI-PM_L1.2+ PCI-PM_L1.1- ASPM_L1.2+ ASPM_L1.1- L1_PM_Substates+
                  PortCommonModeRestoreTime=32us PortTPowerOnTime=10us
        L1SubCtl1: PCI-PM_L1.2- PCI-PM_L1.1- ASPM_L1.2+ ASPM_L1.1-
                   T_CommonMode=0us LTR1.2_Threshold=101376ns
        L1SubCtl2: T_PwrOn=50us

Enable PCI-PM L1 PM Substates for devices below VMD while they are in D0
(see PCIe r6.0, sec 5.5.4).

Subject: [PATCH 1752/2948] PCI: Detect and trust built-in Thunderbolt chips

Some computers with CPUs that lack Thunderbolt features use discrete
Thunderbolt chips to add Thunderbolt functionality. These Thunderbolt
chips are located within the chassis; between the Root Port labeled
ExternalFacingPort and the USB-C port.

These Thunderbolt PCIe devices should be labeled as fixed and trusted, as
they are built into the computer. Otherwise, security policies that rely on
those flags may have unintended results, such as preventing USB-C ports
from enumerating.

Detect the above scenario through the process of elimination.

  1) Integrated Thunderbolt host controllers already have Thunderbolt
     implemented, so anything outside their external facing Root Port is
     removable and untrusted.

     Detect them using the following properties:

       - Most integrated host controllers have the "usb4-host-interface"
         ACPI property, as described here:

         https://learn.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports#mapping-native-protocols-pcie-displayport-tunneled-through-usb4-to-usb4-host-routers

       - Integrated Thunderbolt PCIe Root Ports before Alder Lake do not
         have the "usb4-host-interface" ACPI property. Identify those by
         their PCI IDs instead.

  2) If a Root Port does not have integrated Thunderbolt capabilities, but
     has the "ExternalFacingPort" ACPI property, that means the
     manufacturer has opted to use a discrete Thunderbolt host controller
     that is built into the computer.

     This host controller can be identified by virtue of being located
     directly below an external-facing Root Port that lacks integrated
     Thunderbolt. Label it as trusted and fixed.

     Everything downstream from it is untrusted and removable.

The "ExternalFacingPort" ACPI property is described here:
https://learn.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports#identifying-externally-exposed-pcie-root-ports

Subject: [PATCH 1756/2948] scsi: pm8001: Initialize devices in
 pm8001_alloc_dev()

Devices can be allocated and freed at runtime. For example during a soft
reset all devices are freed and reallocated upon discovery.

Currently the driver fully initializes devices once in pm8001_alloc().
Allows initialization steps to happen during runtime, avoiding any
leftover states from the device being freed.

Subject: [PATCH 1757/2948] scsi: pm8001: Increase request sg length to support
 4MiB requests

Increasing the per-request size maximum to 4MiB (8192 sectors x 512
bytes) runs into the per-device DMA scatter gather list limit
(max_segments) for users of the io vector system calls (e.g. readv and
writev).

Increase the max scatter gather list length to 1024 to enable kernel to
send 4MiB (1024 * 4KiB page size) requests.

Subject: [PATCH 1758/2948] scsi: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/scsi to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

On the way do a few whitespace changes to make indention consistent.

Subject: [PATCH 1766/2948] scsi: sg: Enable runtime power management

In 2010, runtime power management support was implemented in the SCSI
core.  The description of patch "[SCSI] implement runtime Power
Management" mentions that the sg driver is skipped but not why. This
patch enables runtime power management even if an instance of the sg
driver is held open.  Enabling runtime PM for the sg driver is safe
because all interactions of the sg driver with the SCSI device pass
through the block layer (blk_execute_rq_nowait()) and the block layer
already supports runtime PM.

"ufshcd_add_scsi_host: failed to initialize (legacy doorbell mode not
supported)". Fix this by setting the "broken LSDBS" quirk for the
SM8650 development board.

Subject: [PATCH 1770/2948] scsi: st: Add MTIOCGET and MTLOAD to ioctls allowed
 after device reset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Most drives rewind the tape when the device is reset. Reading and writing
are not allowed until something is done to make the tape position match the
user's expectation (e.g., rewind the tape). Add MTIOCGET and MTLOAD to
operations allowed after reset. MTIOCGET is modified to not touch the tape
if pos_unknown is non-zero. The tape location is known after MTLOAD.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently the code starts new tape session when any Unit Attention
(UA) is seen when opening the device. This leads to incorrectly
clearing pos_unknown when the UA is for reset. Set new session only
when the UA is for a new tape.

Date: Mon, 4 Nov 2024 18:50:04 +0100
Subject: [PATCH 1774/2948] staging: gpib: Update messaging and usb_device refs
 in ni_usb

Replace GPIB_DPRINTK with dev_dbg
Replace pr_xxx with dev_xxx wherever possible
Use previously initialized usb_device pointer
for usb_get_dev() and usb_put_dev().

Subject: [PATCH 1775/2948] staging: gpib: Update messaging and usb_device refs
 in agilent_usb

Replace GPIB_DPRINTK with dev_dbg
Replace pr_xxx with dev_xxx wherever possible
Use previously initialized usb_device pointer for usb_put_dev()
Remove commented out console message code.

Subject: [PATCH 1782/2948] staging: gpib: Re-order the lookup tables

Re-order the tables so that the bcm27xx table is used first
as these devices are more popular and numerous than the older ones.
This is slightly more efficient for the later pi3 and subsequent models
but should not be noticable in practice for all users.

Subject: [PATCH 1783/2948] staging: gpib: Correct check for max secondary
 address

GPIB secondary addresses can be between 0 and 31 inclusive
unlike primary addresses where address 31 is not a valid device
address.  When 31 is used as a primary talk address it
forms the UNT (Untalk) command and when used as a listener address it
forms the UNL (Unlisten) commmand.
The library was incorrectly not allowing a secondary address
with a value of 31 to be used.

Subject: [PATCH 1818/2948] serial: sh-sci: Clean sci_ports[0] after at
 earlycon exit

The early_console_setup() function initializes the sci_ports[0].port with
an object of type struct uart_port obtained from the object of type
struct earlycon_device received as argument by the early_console_setup().

It may happen that later, when the rest of the serial ports are probed,
the serial port that was used as earlycon (e.g., port A) to be mapped to a
different position in sci_ports[] and the slot 0 to be used by a different
serial port (e.g., port B), as follows:

sci_ports[0] = port A
sci_ports[X] = port B

In this case, the new port mapped at index zero will have associated data
that was used for earlycon.

In case this happens, after Linux boot, any access to the serial port that
maps on sci_ports[0] (port A) will block the serial port that was used as
earlycon (port B).

To fix this, add early_console_exit() that clean the sci_ports[0] at
earlycon exit time.

Fixes: 0b0cced19ab1 ("serial: sh-sci: Add CONFIG_SERIAL_EARLYCON support")

Subject: [PATCH 1821/2948] usb: typec: ucsi: Convert connector specific
 commands to bitmaps

That allows the fields in those command data structures to
be easily validated. If an unsupported field is accessed, a
warning is generated.

This will not force UCSI version checks to be made in every
place where these data structures are accessed, but it will
make it easier to pinpoint issues that are caused by the
unconditional accesses to those fields, and perhaps more
importantly, allow those issues to be noticed immediately.

Subject: [PATCH 1822/2948] Revert "watchdog: s3c2410_wdt: use
 exynos_get_pmu_regmap_by_phandle() for PMU regs"

This reverts commit 746f0770f916e6c48e422d6a34e67eae16707f0e.

Now that we can register a SoC specific regmap with syscon using
of_syscon_register_regmap() api we can switch back to using
syscon_regmap_lookup_by_phandle() in the client drivers.

 watchdog bindings

Add "samsung-exynosautov920-wdt" compatible to the dt-schema
document. ExynosAutoV920 is new SoC for automotive, similar to
exynosautov9 but some CPU configurations are quite different.

Adds the compatibles and drvdata for the ExynosAuto V920 SoC. This SoC
is almost similar to ExynosAutoV9, but some CPU configurations are quite
different, so it should be added. Plus it also support DBGACK like as
GS101 SoC.

Subject: [PATCH 1835/2948] dt-bindings: PCI: microchip,pcie-host: Add reg for
 Root Port 2

The PCI host controller on PolarFire SoC has multiple Root Port instances,
each with their own bridge and ctrl address spaces. The original binding
has an "apb" register region, and it is expected to be set to the base
address of the Root Complex register space. Some defines in the Linux
driver were used to compute the addresses of the bridge and ctrl address
ranges corresponding to Root Port instance 1.  Some customers want to use
Root Port instance 2 however, which requires changing the defines in the
driver, which is clearly not a portable solution.

Remove this "apb" register region from the binding and add "bridge" &
"ctrl" regions instead, that will directly communicate the address of these
regions for a specific Root Port.

Fixes: 6ee6c89aac35 ("dt-bindings: PCI: microchip: Add Microchip PolarFire host binding")

Subject: [PATCH 1836/2948] PCI: microchip: Add support for using either Root
 Port 1 or 2

The PCI host controller on PolarFire SoC has multiple Root Port instances,
each with their own bridge and ctrl address spaces. The original binding
has an "apb" register region, and it is expected to be set to the base
address of the Root Complex register space. Some defines in the Linux
driver were used to compute the addresses of the bridge and ctrl address
ranges corresponding to Root Port instance 1.  Some customers want to use
Root Port instance 2 however, which requires changing the defines in the
driver, which is clearly not a portable solution.

The binding has been changed from a single register region to a pair,
corresponding to the bridge and ctrl regions respectively, so modify the
driver to read these regions directly from the devicetree rather than
compute them from the base address of the abp region.

To maintain backwards compatibility with the existing binding, the driver
retains code to handle the "abp" reg and computes the base address of the
bridge and ctrl regions using the defines if it is present. reg-names has
always been a required property, so this is safe to do.

 "ti,keystone-pcie" compatible
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

commit 23284ad677a9 ("PCI: keystone: Add support for PCIe EP in AM654x
Platforms") introduced configuring "enum dw_pcie_device_mode" as part of
device data ("struct ks_pcie_of_data"). However it failed to set the
mode for "ti,keystone-pcie" compatible.

Since the mode defaults to "DW_PCIE_UNKNOWN_TYPE", the following error
message is displayed for the v3.65a controller:

  "INVALID device type 0"

Despite the driver probing successfully, the controller may not be
functional in the Root Complex mode of operation.

So, set the mode as Root Complex for "ti,keystone-pcie" compatible to
fix this.

 ks_pcie_other_map_bus()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

K2G forwards the error triggered by a link-down state (e.g., no connected
endpoint device) on the system bus for PCI configuration transactions;
these errors are reported as an SError at system level, which is fatal and
hangs the system.

So, apply fix similar to how it was done in the DesignWare Core driver
commit 15b23906347c ("PCI: dwc: Add link up check in dw_child_pcie_ops.map_bus()").

Our static checker found a bug where set_serial_info() uses a mutex, but
get_serial_info() does not. Fortunately, the impact of this is relatively
minor. It doesn't cause a crash or any other serious issues. However, if a
race condition occurs between set_serial_info() and get_serial_info(),
there is a chance that the data returned by get_serial_info() will be
inconsistent.

Subject: [PATCH 1843/2948] um: set DONTDUMP and DONTFORK flags on KASAN shadow
 memory

There is no point in either dumping the KASAN shadow memory or doing
copy-on-write after a fork on these memory regions.

This considerably speeds up coredump generation.

Subject: [PATCH 1844/2948] um: always include kconfig.h and compiler-version.h

Since commit a95b37e20db9 ("kbuild: get <linux/compiler_types.h> out of
<linux/kconfig.h>") we can safely include these files in userspace code.
Doing so simplifies matters as options do not need to be exported via
asm-offsets.h anymore.

Subject: [PATCH 1847/2948] um: remove broken double fault detection

The show_stack function had some code to detect double faults. However,
the logic is wrong and it would e.g. trigger if a WARNING happened
inside an IRQ.

Remove it without trying to add a new logic. The current behaviour,
which will just fault repeatedly until the IRQ stack is used up and the
host kills UML, seems to be good enough.

Subject: [PATCH 1849/2948] um: virtio_uml: fix call_fd IRQ allocation

If the device does not support slave requests, then the IRQ will not yet
be allocated. So initialize the IRQ to UM_IRQ_ALLOC so that it will be
allocated if none has been assigned yet and store it slightly later when
we know that it will not be immediately unregistered again.

Subject: [PATCH 1854/2948] um: vector: Do not use drvdata in release

The drvdata is not available in release. Let's just use container_of()
to get the vector_device instance. Otherwise, removing a vector device
will result in a crash:

Subject: [PATCH 1855/2948] um: Always dump trace for specified task in
 show_stack

Currently, show_stack() always dumps the trace of the current task.
However, it should dump the trace of the specified task if one is
provided. Otherwise, things like running "echo t > sysrq-trigger"
won't work as expected.

Subject: [PATCH 1861/2948] Input: ads7846 - add dummy command register
 clearing cycle

On STM32MP135F with XPT2046 touch controller attached to SPI bus, it has
been observed that the touch controller locks up after Linux kernel has
finished booting. Adding a dummy cycle on the SPI bus seems to mitigate
the lock up.

The XPTEK XPT2046 controller seems to be an identical clone of TI TSC2046,
the datasheet seems to be a clone of the TI part as well, text seem to be
word to word identical, except all the pictures have been drawn again.

This touch controller is present e.g. on WaveShare 3.2inch RPi LCD (B)
panel, the DTO provided by WaveShare uses 50 kHz SPI clock for this
touch controller, which is unusually low and possibly might have been
used as some sort of workaround for an issue. The SPI LCD on the same
bus uses 16 MHz clock.

SPI bus DT properties spi-cs-setup-delay-ns, spi-cs-hold-delay-ns,
spi-cs-inactive-delay-ns, spi-rx-delay-us, spi-tx-delay-us set to
range of 500ns..5us seem to have no impact on the behavior of the
touch controller, the lock up always occurs. The STM32MP13xx SPI
controller users GPIO control for the nCS pins.

Since the dummy cycle happens after the controller has been put into
power down mode and both ADC and REF regulators have been disabled,
the cycle should have no impact on the configuration of the controller,
i.e. it should be a NOP.

It is unclear whether this problem is specific to this cloned XPT2046
controller, or whether this is also present on TSC2046. A test on
either TSC2046 or ADS7846 would be very welcome.

Subject: [PATCH 1872/2948] bus: mhi: host: Switch trace_mhi_gen_tre fields to
 native endian

Each of the __field() macros were triggering sparse warnings similar to:
trace.h:87:1: sparse: sparse: cast to restricted __le64
trace.h:87:1: sparse: sparse: restricted __le64 degrades to integer
trace.h:87:1: sparse: sparse: restricted __le64 degrades to integer

Change each little endian type to its similarly sized native integer.
Convert inputs into native endian.

Subject: [PATCH 1874/2948] NFS: Clean up locking the nfs_versions list

This patch replaces the nfs_version_mutex and nfs_version_lock with a
single RW lock that protects access to the nfs_versions list.

The mutex around request_module() seemed unnecessary to me, and I
couldn't find any other callers using a lock around calls to
request_module() when I looked.

At the same time, I saw fs/filesystems.c using a RW lock to protect
their filesystems list. This seems like a better idea than a spinlock to
me, so I'm also making that change while I'm here.

Subject: [PATCH 1876/2948] NFS: Rename get_nfs_version() -> find_nfs_version()

We have a put_nfs_version() that handles refcounting on the nfs version
module, but get_nfs_version() does much more work to find a version
module based on version number. Let's change 'get' to 'find' to better
match what it's doing.

Subject: [PATCH 1877/2948] NFS: Clean up find_nfs_version()

It's good practice to check the return value of request_module() to see
if the module has been found. It's also a little easier to follow the
code if __find_nfs_version() doesn't attempt to convert NULL pointers
into -EPROTONOSUPPORT.

Subject: [PATCH 1878/2948] NFS: Implement get_nfs_version()

This is a pair for put_nfs_version(), and is used for incrementing the
reference count on the nfs version module. I also updated the callers I
could find who had this hardcoded up until now.

Push the read_iter and write_iter availability checks down to

This eliminates a redundant nfs_to->nfsd_file_file() call.

Tracepoint strings don't require newlines (and in fact, they are
undesirable).

Subject: [PATCH 1885/2948] SUNRPC: Fix a hang in TLS sock_close if
 sk_write_pending

We've observed an NFS server shrink the TCP window and then reset the TCP
connection as part of a HA failover.  When the connection has TLS, often
the NFS client will hang indefinitely in this stack:

     wait_woken+0x70/0x80
     wait_on_pending_writer+0xe4/0x110 [tls]
     tls_sk_proto_close+0x368/0x3a0 [tls]
     inet_release+0x54/0xb0
     __sock_release+0x48/0xc8
     sock_close+0x20/0x38
     __fput+0xe0/0x2f0
     __fput_sync+0x58/0x70
     xs_reset_transport+0xe8/0x1f8 [sunrpc]
     xs_tcp_shutdown+0xa4/0x190 [sunrpc]
     xprt_autoclose+0x68/0x170 [sunrpc]
     process_one_work+0x180/0x420
     worker_thread+0x258/0x368
     kthread+0x104/0x118
     ret_from_fork+0x10/0x20

This hang prevents the client from closing the socket and reconnecting to
the server.

Because xs_nospace() elevates sk_write_pending, and sk_sndtimeo is
MAX_SCHEDULE_TIMEOUT, tls_sk_proto_close is never able to complete its wait
for pending writes to the socket.  For this case where we are resetting the
transport anyway, we don't expect the socket to ever have write space, so
fix this by simply clearing the sock's sndtimeo under the sock's lock.

Subject: [PATCH 1888/2948] perf build: Include libtraceevent headers directly
 indicated by pkg-config

Currently the libtraceevent's found by pkg-config, which give the
include path as:

  [root@localhost tmp]# pkg-config --cflags libtraceevent
  -I/usr/local/include/traceevent

So we should include the libtraceevent headers directly without
"traceevent/" prefix. Update all the users.

Subject: [PATCH 1890/2948] dt-bindings: iio: adc: ad7380: add adaq4370-4 and
 adaq4380-4 compatible parts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

adaq4370-4 (2MSPS) and adaq4380-4 (4MSPS) are quad-channel precision data
acquisition signal chain μModule solutions compatible with the ad738x
family, with the following differences:

- pin selectable gain in front of each 4 adc
- internal reference is 3V derived from refin-supply (5V)
- additional supplies

To select the gain a new patternProperties is added to describe each
channel. It is restricted to adaq devices.

Subject: [PATCH 1891/2948] iio: adc: ad7380: fix oversampling formula

The formula in the datasheet for oversampling time conversion seems to
be valid when device is at full speed using the maximum number of SDO
lines. The driver currently support only 1 SDO line. The correct formula
is: t_convert = T_CONVERT_0_NS + T_CONVERT_X_NS*(x -
1)*num_channel/number_of_sdo_lines.
It will produce larger delays than what is currently set, but some devices
actually require it.

Subject: [PATCH 1893/2948] iio: adc: ad7380: add support for adaq4370-4 and
 adaq4380-4
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

adaq4370-4 (2MSPS) and adaq4380-4 (4MSPS) are quad-channel precision data
acquisition signal chain μModule solutions compatible with the ad738x
family, with the following differences:

- pin selectable gain in front of each 4 adc
- internal reference is 3V derived from refin-supply (5V)
- additional supplies

This implies that IIO_CHAN_INFO_SCALE can not be shared by type for
these new devices.

Subject: [PATCH 1897/2948] NFSv4.0: Fix a use-after-free problem in the
 asynchronous open()

Yang Erkun reports that when two threads are opening files at the same
time, and are forced to abort before a reply is seen, then the call to
nfs_release_seqid() in nfs4_opendata_free() can result in a
use-after-free of the pointer to the defunct rpc task of the other
thread.
The fix is to ensure that if the RPC call is aborted before the call to
nfs_wait_on_sequence() is complete, then we must call nfs_release_seqid()
in nfs4_open_release() before the rpc_task is freed.

Subject: [PATCH 1898/2948] perf hwmon_pmu: Add hwmon filename parser

hwmon filenames have a specific encoding that will be used to give a
config value. The encoding is described in:
Documentation/hwmon/sysfs-interface.rst
Add a function to parse the filename into consituent enums/ints that
will then be amenable to config encoding.

Note, things are done this way to allow mapping names to config and
back without the use of hash/dynamic lookup tables.

Subject: [PATCH 1900/2948] perf hwmon_pmu: Add a tool PMU exposing events from
 hwmon in sysfs

Add a tool PMU for hwmon events but don't enable.

The hwmon sysfs ABI is defined in
Documentation/hwmon/sysfs-interface.rst. Create a PMU that reads the
hwmon input and can be used in `perf stat` and metrics much as an
uncore PMU can.

For example, when enabled by a later patch, the following shows
reading the CPU temperature and 2 fan speeds alongside the uncore
frequency:
```
$ perf stat -e temp_cpu,fan1,hwmon_thinkpad/fan2/,tool/num_cpus_online/ -M UNCORE_FREQ -I 1000
     1.001153138              52.00 'C   temp_cpu
     1.001153138              2,588 rpm  fan1
     1.001153138              2,482 rpm  hwmon_thinkpad/fan2/
     1.001153138                  8      tool/num_cpus_online/
     1.001153138      1,077,101,397      UNC_CLOCK.SOCKET                 #     1.08 UNCORE_FREQ
     1.001153138      1,012,773,595      duration_time
...
```

The PMUs are named from /sys/class/hwmon/hwmon<num>/name and have an
alias of hwmon<num>.

Hwmon data is presented in multiple <type><number>_<item> files. The
<type><number> is used to identify the event as is the <type> followed
by the contents of the <type>_label file if it exists. The
<type><number>_input file gives the data read by perf.

When enabled by a later patch, in `perf list` the other hwmon <item>
files are used to give a richer description, for example:
```
hwmon:
  temp1
       [Temperature in unit acpitz named temp1. Unit: hwmon_acpitz]
  in0
       [Voltage in unit bat0 named in0. Unit: hwmon_bat0]
  temp_core_0 OR temp2
       [Temperature in unit coretemp named Core 0. crit=100'C,max=100'C crit_alarm=0'C. Unit:
        hwmon_coretemp]
  temp_core_1 OR temp3
       [Temperature in unit coretemp named Core 1. crit=100'C,max=100'C crit_alarm=0'C. Unit:
        hwmon_coretemp]
...
  temp_package_id_0 OR temp1
       [Temperature in unit coretemp named Package id 0. crit=100'C,max=100'C crit_alarm=0'C.
        Unit: hwmon_coretemp]
  temp1
       [Temperature in unit iwlwifi_1 named temp1. Unit: hwmon_iwlwifi_1]
  temp_composite OR temp1
       [Temperature in unit nvme named Composite. alarm=0'C,crit=86.85'C,max=75.85'C,
        min=-273.15'C. Unit: hwmon_nvme]
  temp_sensor_1 OR temp2
       [Temperature in unit nvme named Sensor 1. max=65261.8'C,min=-273.15'C. Unit: hwmon_nvme]
  temp_sensor_2 OR temp3
       [Temperature in unit nvme named Sensor 2. max=65261.8'C,min=-273.15'C. Unit: hwmon_nvme]
  fan1
       [Fan in unit thinkpad named fan1. Unit: hwmon_thinkpad]
  fan2
       [Fan in unit thinkpad named fan2. Unit: hwmon_thinkpad]
...
  temp_cpu OR temp1
       [Temperature in unit thinkpad named CPU. Unit: hwmon_thinkpad]
  temp_gpu OR temp2
       [Temperature in unit thinkpad named GPU. Unit: hwmon_thinkpad]
  curr1
       [Current in unit ucsi_source_psy_usbc000_0 named curr1. max=1.5A. Unit:
        hwmon_ucsi_source_psy_usbc000_0]
  in0
       [Voltage in unit ucsi_source_psy_usbc000_0 named in0. max=5V,min=5V. Unit:
        hwmon_ucsi_source_psy_usbc000_0]
```

As there may be multiple hwmon devices a range of PMU types are
reserved for their use and to identify the PMU as belonging to the
hwmon types.

+TOOL/HWMON EVENTS
+-----------------
+
+Some events don't have an associated PMU instead reading values
+available to software without perf_event_open. As these events don't
+support sampling they can only really be read by tools like perf stat.
+
+Tool events provide times and certain system parameters. Examples
+include duration_time, user_time, system_time and num_cpus_online.
+
+Hwmon events provide easy access to hwmon sysfs data typically in
+/sys/class/hwmon. This information includes temperatures, fan speeds
+and energy usage.

Commit 4a73fca22692 ("perf bpf-prologue: Remove unused file") missed
cleaning up the header file. The code was unnecessary as Commit
3d6dfae88917 ("perf parse-events: Remove BPF event support") removed
building bpf-prologue.c.

Subject: [PATCH 1905/2948] perf dwarf-regs: Remove
 PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET

PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET was used for BPF prologue
support which was removed in Commit 3d6dfae88917 ("perf parse-events:
Remove BPF event support"). The code is no longer used so remove.

Remove the offset from various dwarf-regs.c tables and the dependence
on ptrace.h. Rename structs starting pt_ as the ptrace derived offset is
now removed.

Subject: [PATCH 1906/2948] perf dwarf-regs: Add EM_HOST and EF_HOST defines

Computed from the build architecture defines, EM_HOST and EF_HOST give
values that can be used in dwarf register lookup. Place in
dwarf-regs.h so the value can be shared. Move some dwarf-regs.c
constants used for EM_HOST to dwarf-regs.h. Add CSky constants that
may be missing.

In disasm.c add an include of dwarf-regs.h as the included
arch/*/annotate/instructions.c files make use of the constants and we
want the elf.h/dwarf-regs.h dependency to be explicit.

Subject: [PATCH 1907/2948] perf disasm: Add e_machine/e_flags to struct arch

Currently functions like get_dwarf_regnum only work with the host
architecture. Carry the elf machine and flags in struct arch so that
in disassembly these can be used to allow cross platform disassembly.

Subject: [PATCH 1908/2948] perf dwarf-regs: Pass accurate disassembly machine
 to get_dwarf_regnum

Rather than pass 0/EM_NONE, use the value computed in the disasm
struct arch. Switch the EM_NONE case to EM_HOST, rewriting EM_NONE if
it were passed to get_dwarf_regnum. Pass a flags value as
architectures like csky need the flags to determine the ABI variant.

Subject: [PATCH 1910/2948] perf dwarf-regs: Move x86 dwarf-regs out of arch

Move arch/x86/util/dwarf-regs.c to util/dwarf-regs-x86.c and compile
in unconditionally. To avoid get_arch_regnum being duplicated, rename
to get_x86_regnum and add to get_dwarf_regnum switch.

For get_arch_regstr, this was unused on x86 unless the machine type
was EM_NONE. Map that case to EM_HOST and remove get_arch_regstr from
dwarf-regs-x86.c.

Subject: [PATCH 1911/2948] perf arm64: Remove dwarf-regs.c

The file just provides the function get_arch_regstr, however, if in
the only caller get_dwarf_regstr EM_HOST is used for the EM_NONE case
the function can never be called. So remove as dead code. Tidy up the
EM_NONE cases for arm64 in dwarf-regs.c.

Subject: [PATCH 1913/2948] perf dwarf-regs: Move csky dwarf-regs out of arch

Move arch/csky/util/dwarf-regs.c to util/dwarf-regs-csky.c and compile
in unconditionally. To avoid get_arch_regstr being duplicated, rename
to get_csky_regstr and add to get_dwarf_regstr switch.

Update #ifdefs to allow ABI V1 and V2 tables at the same
time. Determine the table from the ELF flags.

Subject: [PATCH 1916/2948] perf dwarf-regs: Move powerpc dwarf-regs out of
 arch

Move arch/powerpc/util/dwarf-regs.c to util/dwarf-regs-powerpc.c and
compile in unconditionally. get_arch_regstr is redundant when EM_NONE
is treated as EM_HOST so remove and update dwarf-regs.c conditions.
Make get_powerpc_regs unconditionally available whwn libdw is.

Subject: [PATCH 1917/2948] perf riscv: Remove dwarf-regs.c and add
 dwarf-regs-table.h

The file just provides the function get_arch_regstr, however, if in
the only caller get_dwarf_regstr EM_HOST is used for the EM_NONE case,
and the register table is provided in a header file, the function can
never be called. So remove as dead code. Tidy up the EM_NONE cases for
riscv in dwarf-regs.c.

Subject: [PATCH 1918/2948] perf s390: Remove dwarf-regs.c

The file just provides the function get_arch_regstr, however, if in
the only caller get_dwarf_regstr EM_HOST is used for the EM_NONE case
the function can never be called. So remove as dead code. Tidy up the
EM_NONE cases for s390 in dwarf-regs.c.

Subject: [PATCH 1921/2948] perf xtensa: Remove dwarf-regs.c

The file just provides the function get_arch_regstr, however, if in
the only caller get_dwarf_regstr EM_HOST is used for the EM_NONE case
the function can never be called. So remove as dead code. As this is
the only file in the arch/xtensa/util clean up Build files. Tidy up the
EM_NONE cases for xtensa in dwarf-regs.c.

Subject: [PATCH 1923/2948] perf build: Remove PERF_HAVE_DWARF_REGS

PERF_HAVE_DWARF_REGS was true when an architecture had a dwarf-regs.c
file. There are no more architecture dwarf-regs.c files, selection is
done using constants from the ELF file rather than conditional
compilation. When removing PERF_HAVE_DWARF_REGS was the only variable
in the Makefile, remove the Makefile.

Add missing SPDX for RISC-V Makefile.

Subject: [PATCH 1924/2948] nfs/localio: must clear res.replen in
 nfs_local_read_done

Otherwise memory corruption can occur due to NFSv3 LOCALIO reads
leaving garbage in res.replen:
- nfs3_read_done() copies that into server->read_hdrsize; from there
  nfs3_proc_read_setup() copies it to args.replen in new requests.
- nfs3_xdr_enc_read3args() passes that to rpc_prepare_reply_pages()
  which includes it in hdrsize for xdr_init_pages, so that rq_rcv_buf
  contains a ridiculous len.
- This is copied to rq_private_buf and xs_read_stream_request()
  eventually passes the kvec to sock_recvmsg() which receives incoming
  data into entirely the wrong place.

This is easily reproduced with NFSv3 LOCALIO that is servicing reads
when it is made to pivot back to using normal RPC.  This switch back
to using normal NFSv3 with RPC can occur for a few reasons but this
issue was exposed with a test that stops and then restarts the NFSv3
server while LOCALIO is performing heavy read IO.

 folio_set_private by folio_attach_private"

This reverts commit 03e02b94171b1985dd0aa184296fe94425b855a3.

As was pointed out during code review, there is no need to use
folio_attach_private()/folio_detach_private() when a refcount to the
folio is already carried by the struct nfs_page.

Subject: [PATCH 1927/2948] staging: greybus: uart: Fix atomicity violation in
 get_serial_info()

Our static checker found a bug where set_serial_info() uses a mutex, but
get_serial_info() does not. Fortunately, the impact of this is relatively
minor. It doesn't cause a crash or any other serious issues. However, if a
race condition occurs between set_serial_info() and get_serial_info(),
there is a chance that the data returned by get_serial_info() will be
meaningless.

Subject: [PATCH 1935/2948] staging: gpib: avoid unintended sign extension

The code was basically like this (assuming size_t can be u64)
    var_u64 |= var_u8 << 24
var_u8 is first promoted to i32 and then the shift is done. Next, it is
promoted to u64 by first signextending to 64 bits. This is very unlikely
what was intended. So now it is first forced to u32.
    var_u64 |= (u32)var_u8 << 24

This was detected by Coverity, CID 1600792.

Commit 94a20fb9af16 ("sysfs: treewide: constify attribute callback of

Subject: [PATCH 1939/2948] spmi: pmic-arb: fix return path in
 for_each_available_child_of_node()

This loop requires explicit calls to of_node_put() upon early exits
(break, goto, return) to decrement the child refcounter and avoid memory
leaks if the child is not required out of the loop.

A more robust solution is using the scoped variant of the macro, which
automatically calls of_node_put() when the child goes out of scope.

Subject: [PATCH 1942/2948] mei: vsc: Do not re-enable interrupt from
 vsc_tp_reset()

The only 2 callers of vsc_tp_reset() are:

1. mei_vsc_hw_reset(), which immediataly calls vsc_tp_intr_disable()
   afterwards.

2. vsc_tp_shutdown() which immediately calls free_irq() afterwards.

So neither actually wants the interrupt to be enabled after resetting
the chip and having the interrupt enabled for a short time afer
the reset is undesirable.

Drop the enable_irq() call from vsc_tp_reset(), so that the interrupt
is left disabled after vsc_tp_reset().

Subject: [PATCH 1944/2948] usb: gadget: function: remove redundant else
 statement

After an initial range change on the insigned int alt being > 1
the only possible values for alt are 0 or 1. Therefore the else
statement for values other than 0 or 1 is redundant and can be
removed. Replace the else if (all == 1) check with just an else.

 connector_status

UCSI connector's indices start from 1 up to 3, PMIC_GLINK_MAX_PORTS.
Correct the condition in the pmic_glink_ucsi_connector_status()
callback, fixing Type-C orientation reporting for the third USB-C
connector.

 orientation-aware ports

Instead of checking if any of the USB-C ports have orientation GPIO and
thus is orientation-aware, check for the GPIO for the port being
registered. There are no boards that are affected by this change at this
moment, so the patch is not marked as a fix, but it might affect other
boards in future.

Subject: [PATCH 1949/2948] rust: sync: add global lock support

Add support for creating global variables that are wrapped in a mutex or
spinlock.

The implementation here is intended to replace the global mutex
workaround found in the Rust Binder RFC [1]. In both cases, the global
lock must be initialized before first use. The macro is unsafe to use
for the same reason.

The separate initialization step is required because it is tricky to
access the value of __ARCH_SPIN_LOCK_UNLOCKED from Rust. Doing so will
require changes to the C side. That change will happen as a follow-up to
this patch.

Subject: [PATCH 1950/2948] rtc: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/rtc to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

Subject: [PATCH 1952/2948] rtc: st-lpc: Use IRQF_NO_AUTOEN flag in
 request_irq()

If request_irq() fails in st_rtc_probe(), there is no need to enable
the irq, and if it succeeds, disable_irq() after request_irq() still has
a time gap in which interrupts can come.

request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable when
request IRQ.

Subject: [PATCH 1954/2948] rust: fix size_t in bindgen prototypes of C
 builtins

Without `-fno-builtin`, for functions like memcpy/memmove (and many
others), bindgen seems to be using the clang-provided prototype. This
prototype is ABI-wise compatible, but the issue is that it does not have
the same information as the source code w.r.t. typedefs.

For example, bindgen generates the following:

    extern "C" {
        pub fn strlen(s: *const core::ffi::c_char) -> core::ffi::c_ulong;
    }

note that the return type is `c_ulong` (i.e. unsigned long), despite the
size_t-is-usize behavior (this is default, and we have not opted out
from it using --no-size_t-is-usize).

Similarly, memchr's size argument should be of type `__kernel_size_t`,
but bindgen generates `c_ulong` directly.

We want to ensure any `size_t` is translated to Rust `usize` so that we
can avoid having them be different type on 32-bit and 64-bit
architectures, and hence would require a lot of excessive type casts
when calling FFI functions.

I found that this bindgen behavior (which probably is caused by
libclang) can be disabled by `-fno-builtin`. Using the flag for compiled
code can result in less optimisation because compiler cannot assume
about their properties anymore, but this should not affect bindgen.

[ Trevor asked: "I wonder how reliable this behavior is. Maybe bindgen
  could do a better job controlling this, is there an open issue?".

  Gary replied: ..."apparently this is indeed the suggested approach in
  https://github.com/rust-lang/rust-bindgen/issues/1770". - Miguel ]

Subject: [PATCH 1956/2948] m68k: coldfire/device.c: only build FEC when HW
 macros are defined

When CONFIG_FEC is set (due to COMPILE_TEST) along with
CONFIG_M54xx, coldfire/device.c has compile errors due to
missing MCFEC_* and MCF_IRQ_FEC_* symbols.

Make the whole FEC blocks dependent on having the HW macros
defined, rather than on CONFIG_FEC itself.

This fix is very similar to commit e6e1e7b19fa1 ("m68k: coldfire/device.c: only build for MCF_EDMA when h/w macros are defined")

Subject: [PATCH 1957/2948] rust: map `__kernel_size_t` and friends also to
 usize/isize

Currently bindgen has special logic to recognise `size_t` and `ssize_t`
and map them to Rust `usize` and `isize`. Similarly, `ptrdiff_t` is
mapped to `isize`.

However this falls short for `__kernel_size_t`, `__kernel_ssize_t` and
`__kernel_ptrdiff_t`. To ensure that they are mapped to usize/isize
rather than 32/64 integers depending on platform, blocklist them in
bindgen parameters and manually provide their definition.

Currently FFI integer types are defined in libcore. This commit creates
the `ffi` crate and asks bindgen to use that crate for FFI integer types
instead of `core::ffi`.

This commit is preparatory and no type changes are made in this commit
yet.

Subject: [PATCH 1959/2948] rtc: isl12022: Prepare for extending rtc device
 drvdata

Add a struct to hold the regmap pointer, so more information can be added.

This is morally a revert of commit f525b210e9d4 ("rtc: isl12022: Get rid of
unneeded private struct isl12022").

Subject: [PATCH 1960/2948] rtc: isl12022: Add alarm support

The ISL12022 RTC has a combined INT/fOUT pin, which can be used for alarm
interrupt when frequency output is not enabled.

The device-tree bindings should ensure that interrupt and clock output is
not enabled at the same time.

Subject: [PATCH 1962/2948] fpga: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/fpga to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

A few white space changes are included to make indention consistent.

Subject: [PATCH 1964/2948] riscv: Move cpufeature.h macros into their own
 header

asm/cmpxchg.h will soon need riscv_has_extension_unlikely() macros and
then needs to include asm/cpufeature.h which introduces a lot of header
circular dependencies.

So move the riscv_has_extension_XXX() macros into their own header which
prevents such circular dependencies by including a restricted number of
headers.

Subject: [PATCH 1965/2948] riscv: Do not fail to build on byte/halfword
 operations with Zawrs

riscv does not have lr instructions on byte and halfword but the
qspinlock implementation actually uses such atomics provided by the
Zabha extension, so those sizes are legitimate.

Then instead of failing to build, just fallback to the !Zawrs path.

Subject: [PATCH 1969/2948] riscv: Improve zacas fully-ordered cmpxchg()

The current fully-ordered cmpxchgXX() implementation results in:

  amocas.X.rl     a5,a4,(s1)
  fence           rw,rw

This provides enough sync but we can actually use the following better
mapping instead:

  amocas.X.aqrl   a5,a4,(s1)

Subject: [PATCH 1970/2948] riscv: Implement arch_cmpxchg128() using Zacas

Now that Zacas is supported in the kernel, let's use the double word
atomic version of amocas to improve the SLUB allocator.

Note that we have to select fixed registers, otherwise gcc fails to pick
even registers and then produces a reserved encoding which fails to
assemble.

Subject: [PATCH 1972/2948] asm-generic: ticket-lock: Reuse arch_spinlock_t of
 qspinlock

The arch_spinlock_t of qspinlock has contained the atomic_t val, which
satisfies the ticket-lock requirement. Thus, unify the arch_spinlock_t
into qspinlock_types.h. This is the preparation for the next combo
spinlock.

Subject: [PATCH 1976/2948] riscv: Add qspinlock support

In order to produce a generic kernel, a user can select
CONFIG_COMBO_SPINLOCKS which will fallback at runtime to the ticket
spinlock implementation if Zabha or Ziccrse are not present.

Note that we can't use alternatives here because the discovery of
extensions is done too late and we need to start with the qspinlock
implementation because the ticket spinlock implementation would pollute
the spinlock value, so let's use static keys.

This is largely based on Guo's work and Leonardo reviews at [1].

Subject: [PATCH 1977/2948] perf disasm: Introduce
 symbol__disassemble_objdump()

With the first disassemble method in perf, the parsing of objdump
output, just like we have for llvm and capstone.

This paves the way to allow the user to specify what disassemblers are
preferred and to also to at some point allow building without the
objdump method.

Subject: [PATCH 1978/2948] NFSD: Prevent a potential integer overflow

If the tag length is >= U32_MAX - 3 then the "length + 4" addition
can result in an integer overflow. Address this by splitting the
decoding into several steps so that decode_cb_compound4res() does
not have to perform arithmetic on the unsafe length value.

Subject: [PATCH 1981/2948] NFSD: Remove unused function parameter

Clean up: Commit 65294c1f2c5e ("nfsd: add a new struct file caching
facility to nfsd") moved the fh_verify() call site out of
nfsd_open(). That was the only user of nfsd_open's @rqstp parameter,
so that parameter can be removed.

Subject: [PATCH 1982/2948] xdrgen: Exit status should be zero on success

To use xdrgen in Makefiles, it needs to exit with a zero status if
the compilation worked. Otherwise the make command fails with an
error.

I misread RFC 4506. The built-in data type is called simply
"string", as there is no fixed-length variety.

+
+For variables that might contain only a small number values, it
+is more efficient to avoid the byte-swap when encoding or decoding

+codes. For example:
+
+  pragma big_endian nfsstat3;
+
+In this case, when generating an XDR struct or union containing a

+"__be32" instead of "enum nfsstat3". XDR unions then switch on the
+non-byte-swapped value of that field.

Subject: [PATCH 1989/2948] xdrgen: Track constant values

In order to compute the numeric on-the-wire width of XDR types,
xdrgen needs to keep track of the numeric value of constants that
are defined in the input specification so it can perform
calculations with those values.

Subject: [PATCH 1990/2948] xdrgen: Keep track of on-the-wire data type widths

The generic parts of the RPC layer need to know the widths (in
XDR_UNIT increments) of the XDR data types defined for each
protocol.

As a first step, add dictionaries to keep track of the symbolic and
actual maximum XDR width of XDR types.

This makes it straightforward to look up the width of a type by its
name. The built-in dictionaries are pre-loaded with the widths of
the built-in XDR types as defined in RFC 4506.

Subject: [PATCH 2001/2948] xdrgen: XDR width for union types

Not yet complete.

The tool doesn't do any math yet. Thus, even though the maximum XDR
width of a union is the width of the union enumerator plus the width
of its largest arm, we're using the sum of all the elements of the
union for the moment.

This means that buffer size requirements are overestimated, and that
the generated maxsize macro cannot yet be used for determining data
element alignment in the XDR buffer.

Subject: [PATCH 2004/2948] nfsd: drop inode parameter from
 nfsd4_change_attribute()

The inode that nfs4_open_delegation() passes to this function is
wrong, which throws off the result. The inode will end up getting a
directory-style change attr instead of a regular-file-style one.

Fix up nfs4_delegation_stat() to fetch STATX_MODE, and then drop the
inode parameter from nfsd4_change_attribute(), since it's no longer
needed.

Fixes: c5967721e106 ("NFSD: handle GETATTR conflict with write delegation")

Subject: [PATCH 2005/2948] nfsd: drop the ncf_cb_bmap field

This is always the same value, and in a later patch we're going to need
to set bits in WORD2. We can simplify this code and save a little space
in the delegation too. Just hardcode the bitmap in the callback encode
function.

Subject: [PATCH 2007/2948] nfsd: have nfsd4_deleg_getattr_conflict pass back
 write deleg pointer

Currently we pass back the size and whether it has been modified, but
those just mirror values tracked inside the delegation. In a later
patch, we'll need to get at the timestamps in the delegation too, so
just pass back a reference to the write delegation, and use that to
properly override values in the iattr.

Subject: [PATCH 2008/2948] PCI: Make pci_stop_dev() concurrent safe

Use the atomic ADDED flag to ensure concurrent callers can't attempt to
stop the device multiple times. Callers should currently all be holding the
pci_rescan_remove_lock, so there shouldn't be an existing race. But that
global lock can cause lock dependency issues, so this is preparing to
reduce reliance on that lock by using the existing existing atomic bit ops.

Simplify __pci_walk_bus() by moving the pci_bus_sem mutex into
pci_walk_bus(), the only place it is needed, and removing the parameter
that told __pci_walk_bus() whether to acquire the mutex.

Subject: [PATCH 2011/2948] PCI: Convert __pci_walk_bus() to be recursive
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The original implementation of __pci_walk_bus() chose a non-recursive walk,
presumably as a precaution on stack use. We do recursive bus walking in
other places though. For example:

  pci_bus_resettable()
  pci_stop_bus_device()
  pci_remove_bus_device()
  pci_bus_allocate_dev_resources()

So recursive pci bus walking is well tested and safe, and is easier to
follow.

Convert __pci_walk_bus() to be recursive to make it easier to introduce
finer grain locking in the future.

Subject: [PATCH 2012/2948] PCI: Store all PCIe Supported Link Speeds
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PCIe bandwidth controller added by a subsequent commit will require
selecting PCIe Link Speeds that are lower than the Maximum Link Speed.

The struct pci_bus only stores max_bus_speed. Even if PCIe r6.1 sec 8.2.1
currently disallows gaps in supported Link Speeds, the Implementation Note
in PCIe r6.1 sec 7.5.3.18, recommends determining supported Link Speeds
using the Supported Link Speeds Vector in the Link Capabilities 2 Register
(when available) to "avoid software being confused if a future
specification defines Links that do not require support for all slower
speeds."

Reuse code in pcie_get_speed_cap() to add pcie_get_supported_speeds() to
query the Supported Link Speeds Vector of a PCIe device. The value is taken
directly from the Supported Link Speeds Vector or synthesized from the Max
Link Speed in the Link Capabilities Register when the Link Capabilities 2
Register is not available.

The Supported Link Speeds Vector in the Link Capabilities Register 2
corresponds to the bus below on Root Ports and Downstream Ports, whereas it
corresponds to the bus above on Upstream Ports and Endpoints (PCIe r6.1 sec
7.5.3.18):

  Supported Link Speeds Vector - This field indicates the supported Link
  speed(s) of the associated Port.

Add supported_speeds into the struct pci_dev that caches the
Supported Link Speeds Vector.

supported_speeds contains a set of Link Speeds only in the case where PCIe
Link Speed can be determined. Root Complex Integrated Endpoints do not have
a well-defined Link Speed because they do not implement either of the Link
Capabilities Registers, which is allowed by PCIe r6.1 sec 7.5.3 (the same
limitation applies to determining cur_bus_speed and max_bus_speed that are
PCI_SPEED_UNKNOWN in such case). This is of no concern from PCIe bandwidth
controller point of view because such devices are not attached into a PCIe
Root Port that could be controlled.

The supported_speeds field keeps the extra reserved zero at the least
significant bit to match the Link Capabilities 2 Register layout.

An attempt was made to store supported_speeds field into the struct pci_bus
as an intersection of both ends of the Link, however, the subordinate
struct pci_bus is not available early enough. The Target Speed quirk (in
pcie_failed_link_retrain()) can run either during initial scan or later,
requiring it to use the API provided by the PCIe bandwidth controller to
set the Target Link Speed in order to co-exist with the bandwidth
controller. When the Target Speed quirk is calling the bandwidth controller
during initial scan, the struct pci_bus is not yet initialized. As such,
storing supported_speeds into the struct pci_bus is not viable.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

pcie_update_link_speed() is passed the Link Status register but not all
callers have that value at hand nor need the value.

Refactor pcie_update_link_speed() to include reading the Link Status
register and create __pcie_update_link_speed() which can be used by the
hotplug code that has the register value at hand beforehand (and needs the
value for other purposes).

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Target Speed quirk in pcie_failed_link_retrain() uses the presence of
LBMS bit as one of the triggering conditions, effectively monopolizing the
use of that bit. An upcoming change will introduce a PCIe bandwidth
controller which sets up an interrupt to track LBMS. As LBMS will be
cleared by the interrupt handler, the Target Speed quirk will no longer be
able to observe LBMS directly.

As a preparatory step for the change, extract the LBMS seen check from
pcie_failed_link_retrain() into a new function pcie_lmbs_seen().

Subject: [PATCH 2017/2948] rtc: mt6359: Add RTC hardware range and add support
 for start-year

Add the RTC hardware range parameters to enable the possibility
of using the `start-year` devicetree property which, if present,
will set the start_secs parameter by overriding the defaults
that this driver is setting;

To keep compatibility with (hence have the same date/time reading
as) the old behavior, set:
 - range_min to 1900-01-01 00:00:00
 - range_max to 2027-12-31 23:59:59 (HW year max range is 0-127)
 - start_secs defaulting to 1968-01-02 00:00:00

Please note that the oddness of starting from January 2nd is not
a hardware quirk and it's done only to get the same date/time
reading as an RTC which time was set before this commit.

Also remove the RTC_MIN_YEAR_OFFSET addition and subtraction in
callbacks set_time() and read_time() respectively, as now this
is already done by the API.

Subject: [PATCH 2018/2948] rtc: mt6359: Use RTC_TC_DOW hardware register for
 wday

Instead of calculating the number of full days since Sunday with
(days + 4) % 7, read (and write) that to the RTC Day-of-week Time
Counter register (RTC_TC_DOW).

Some transformation (addition and subtraction for set/get) is
still done, as this register's range is [1..7], while the tm_wday
in struct tm's range is [0..6].

Please note that this was added only to set_time() and read_time()
callbacks because set_alarm() and read_alarm() are setting a bit
in RTC_AL_MASK to ignore DOW for RTC HW alarms for unknown reasons.

'bat-detect-gpio' property. Document this property and mark it
as deprecated.

The DT bindings specify the property as 'battery-detect-gpios', add
handling for it. Keep fallback to the deprecated 'bat-detect-gpio' property
to keep compatibility with older DTS.

Subject: [PATCH 2029/2948] rtc: check if __rtc_read_time was successful in
 rtc_timer_do_work()

If the __rtc_read_time call fails,, the struct rtc_time tm; may contain
uninitialized data, or an illegal date/time read from the RTC hardware.

When calling rtc_tm_to_ktime later, the result may be a very large value
(possibly KTIME_MAX). If there are periodic timers in rtc->timerqueue,
they will continually expire, may causing kernel softlockup.

Subject: [PATCH 2032/2948] hung_task: add detect count for hung tasks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Patch series "add detect count for hung tasks", v2.

This patchset adds a counter, hung_task_detect_count, to track the number
of times hung tasks are detected.

IHMO, hung tasks are a critical metric.  Currently, we detect them by
periodically parsing dmesg.  However, this method isn't as user-friendly
as using a counter.

Sometimes, a short-lived issue with NIC or hard drive can quickly decrease
the hung_task_warnings to zero.  Without warnings, we must directly access
the node to ensure that there are no more hung tasks and that the system
has recovered.  After all, load average alone cannot provide a clear
picture.

Once this counter is in place, in a high-density deployment pattern, we
plan to set hung_task_timeout_secs to a lower number to improve stability,
even though this might result in false positives.  And then we can set a
time-based threshold: if hung tasks last beyond this duration, we will
automatically migrate containers to other nodes.  Based on past
experience, this approach could help avoid many production disruptions.

Moreover, just like other important events such as OOM that already have
counters, having a dedicated counter for hung tasks makes sense ;)

Subject: [PATCH 2034/2948] ocfs2: fix uninitialized value in
 ocfs2_file_read_iter()

Syzbot has reported the following KMSAN splat:

 do_syscall_64+0xcd/0x1e0
 entry_SYSCALL_64_after_hwframe+0x77/0x7f

Since an instance of 'struct kiocb' may be passed from the block layer
with 'private' field uninitialized, introduce 'ocfs2_iocb_init_rw_locked()'
and use it from where 'ocfs2_dio_end_io()' might take care, i.e. in
'ocfs2_file_read_iter()' and 'ocfs2_file_write_iter()'.

Subject: [PATCH 2036/2948] util_macros.h: fix/rework find_closest() macros

A bug was found in the find_closest() (find_closest_descending() is also
affected after some testing), where for certain values with small
progressions, the rounding (done by averaging 2 values) causes an
incorrect index to be returned.  The rounding issues occur for
progressions of 1, 2 and 3.  It goes away when the progression/interval
between two values is 4 or larger.

It's particularly bad for progressions of 1.  For example if there's an
array of 'a = { 1, 2, 3 }', using 'find_closest(2, a ...)' would return 0
(the index of '1'), rather than returning 1 (the index of '2').  This
means that for exact values (with a progression of 1), find_closest() will
misbehave and return the index of the value smaller than the one we're
searching for.

For progressions of 2 and 3, the exact values are obtained correctly; but
values aren't approximated correctly (as one would expect).  Starting with
progressions of 4, all seems to be good (one gets what one would expect).

While one could argue that 'find_closest()' should not be used for arrays
with progressions of 1 (i.e. '{1, 2, 3, ...}', the macro should still
behave correctly.

The bug was found while testing the 'drivers/iio/adc/ad7606.c',
specifically the oversampling feature.
For reference, the oversampling values are listed as:
   static const unsigned int ad7606_oversampling_avail[7] = {
          1, 2, 4, 8, 16, 32, 64,
   };

When doing:
  1. $ echo 1 > /sys/bus/iio/devices/iio\:device0/oversampling_ratio
     $ cat /sys/bus/iio/devices/iio\:device0/oversampling_ratio
     1  # this is fine
  2. $ echo 2 > /sys/bus/iio/devices/iio\:device0/oversampling_ratio
     $ cat /sys/bus/iio/devices/iio\:device0/oversampling_ratio
     1  # this is wrong; 2 should be returned here
  3. $ echo 3 > /sys/bus/iio/devices/iio\:device0/oversampling_ratio
     $ cat /sys/bus/iio/devices/iio\:device0/oversampling_ratio
     2  # this is fine
  4. $ echo 4 > /sys/bus/iio/devices/iio\:device0/oversampling_ratio
     $ cat /sys/bus/iio/devices/iio\:device0/oversampling_ratio
     4  # this is fine
And from here-on, the values are as correct (one gets what one would
expect.)

While writing a kunit test for this bug, a peculiar issue was found for the
array in the 'drivers/hwmon/ina2xx.c' & 'drivers/iio/adc/ina2xx-adc.c'
drivers. While running the kunit test (for 'ina226_avg_tab' from these
drivers):
  * idx = find_closest([-1 to 2], ina226_avg_tab, ARRAY_SIZE(ina226_avg_tab));
    This returns idx == 0, so value.
  * idx = find_closest(3, ina226_avg_tab, ARRAY_SIZE(ina226_avg_tab));
    This returns idx == 0, value 1; and now one could argue whether 3 is
    closer to 4 or to 1. This quirk only appears for value '3' in this
    array, but it seems to be a another rounding issue.
  * And from 4 onwards the 'find_closest'() works fine (one gets what one
    would expect).

This change reworks the find_closest() macros to also check the difference
between the left and right elements when 'x'. If the distance to the right
is smaller (than the distance to the left), the index is incremented by 1.
This also makes redundant the need for using the DIV_ROUND_CLOSEST() macro.

In order to accommodate for any mix of negative + positive values, the
internal variables '__fc_x', '__fc_mid_x', '__fc_left' & '__fc_right' are
forced to 'long' type. This also addresses any potential bugs/issues with
'x' being of an unsigned type. In those situations any comparison between
signed & unsigned would be promoted to a comparison between 2 unsigned
numbers; this is especially annoying when '__fc_left' & '__fc_right'
underflow.

The find_closest_descending() macro was also reworked and duplicated from
the find_closest(), and it is being iterated in reverse. The main reason
for this is to get the same indices as 'find_closest()' (but in reverse).
The comparison for '__fc_right < __fc_left' favors going the array in
ascending order.
For example for array '{ 1024, 512, 256, 128, 64, 16, 4, 1 }' and x = 3, we
get:
    __fc_mid_x = 2
    __fc_left = -1
    __fc_right = -2
    Then '__fc_right < __fc_left' evaluates to true and '__fc_i++' becomes 7
    which is not quite incorrect, but 3 is closer to 4 than to 1.

This change has been validated with the kunit from the next patch.

Subject: [PATCH 2037/2948] lib: util_macros_kunit: add kunit test for
 util_macros.h

A bug was found in the find_closest() (find_closest_descending() is also
affected after some testing), where for certain values with small
progressions of 1, 2 & 3, the rounding (done by averaging 2 values) causes
an incorrect index to be returned.

The bug is described in more detail in the commit which fixes the bug.
This commit adds a kunit test to validate that the fix works correctly.

This kunit test adds some of the arrays (from the driver-sphere) that seem
to produce issues with the 'find_closest()' macro.  Specifically the one
from ad7606 driver (with which the bug was found) and from the ina2xx
drivers, which shows the quirk with 'find_closest()' with elements in a
array that have an interval of 3.

For the find_closest_descending() tests, the same arrays are used as for
the find_closest(), but in reverse; the idea is that
'find_closest_descending()' should return the sames indices as
'find_closest()' but in reverse.

For testing both macros, there are 4 special arrays created, one for
testing find_closest{_descending}() for arrays of progressions 1, 2, 3 and
4.  The idea is to show that (for progressions of 1, 2 & 3) the fix works
as expected.  When removing the fix, the issues should start to show up.

Then an extra array of negative and positive values is added.  There are
currently no such arrays within drivers, but one could expect that these
macros behave correctly even for such arrays.

To run this kunit:
  ./tools/testing/kunit/kunit.py run "*util_macros*"

to user space.

No functional change intended.

Subject: [PATCH 2039/2948] usb: musb: Fix hardware lockup on first Rx endpoint
 request
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There is a possibility that a request's callback could be invoked from
usb_ep_queue() (call trace below, supplemented with missing calls):

req->complete from usb_gadget_giveback_request
	(drivers/usb/gadget/udc/core.c:999)
usb_gadget_giveback_request from musb_g_giveback
	(drivers/usb/musb/musb_gadget.c:147)
musb_g_giveback from rxstate
	(drivers/usb/musb/musb_gadget.c:784)
rxstate from musb_ep_restart
	(drivers/usb/musb/musb_gadget.c:1169)
musb_ep_restart from musb_ep_restart_resume_work
	(drivers/usb/musb/musb_gadget.c:1176)
musb_ep_restart_resume_work from musb_queue_resume_work
	(drivers/usb/musb/musb_core.c:2279)
musb_queue_resume_work from musb_gadget_queue
	(drivers/usb/musb/musb_gadget.c:1241)
musb_gadget_queue from usb_ep_queue
	(drivers/usb/gadget/udc/core.c:300)

According to the docstring of usb_ep_queue(), this should not happen:

"Note that @req's ->complete() callback must never be called from within
usb_ep_queue() as that can create deadlock situations."

In fact, a hardware lockup might occur in the following sequence:

1. The gadget is initialized using musb_gadget_enable().
2. Meanwhile, a packet arrives, and the RXPKTRDY flag is set, raising an
   interrupt.
3. If IRQs are enabled, the interrupt is handled, but musb_g_rx() finds an
   empty queue (next_request() returns NULL). The interrupt flag has
   already been cleared by the glue layer handler, but the RXPKTRDY flag
   remains set.
4. The first request is enqueued using usb_ep_queue(), leading to the call
   of req->complete(), as shown in the call trace above.
5. If the callback enables IRQs and another packet is waiting, step (3)
   repeats. The request queue is empty because usb_g_giveback() removes the
   request before invoking the callback.
6. The endpoint remains locked up, as the interrupt triggered by hardware
   setting the RXPKTRDY flag has been handled, but the flag itself remains
   set.

For this scenario to occur, it is only necessary for IRQs to be enabled at
some point during the complete callback. This happens with the USB Ethernet
gadget, whose rx_complete() callback calls netif_rx(). If called in the
task context, netif_rx() disables the bottom halves (BHs). When the BHs are
re-enabled, IRQs are also enabled to allow soft IRQs to be processed. The
gadget itself is initialized at module load (or at boot if built-in), but
the first request is enqueued when the network interface is brought up,
triggering rx_complete() in the task context via ioctl(). If a packet
arrives while the interface is down, it can prevent the interface from
receiving any further packets from the USB host.

The situation is quite complicated with many parties involved. This
particular issue can be resolved in several possible ways:

1. Ensure that callbacks never enable IRQs. This would be difficult to
   enforce, as discovering how netif_rx() interacts with interrupts was
   already quite challenging and u_ether is not the only function driver.
   Similar "bugs" could be hidden in other drivers as well.
2. Disable MUSB interrupts in musb_g_giveback() before calling the callback
   and re-enable them afterwars (by calling musb_{dis,en}able_interrupts(),
   for example). This would ensure that MUSB interrupts are not handled
   during the callback, even if IRQs are enabled. In fact, it would allow
   IRQs to be enabled when releasing the lock. However, this feels like an
   inelegant hack.
3. Modify the interrupt handler to clear the RXPKTRDY flag if the request
   queue is empty. While this approach also feels like a hack, it wastes
   CPU time by attempting to handle incoming packets when the software is
   not ready to process them.
4. Flush the Rx FIFO instead of calling rxstate() in musb_ep_restart().
   This ensures that the hardware can receive packets when there is at
   least one request in the queue. Once IRQs are enabled, the interrupt
   handler will be able to correctly process the next incoming packet
   (eventually calling rxstate()). This approach may cause one or two
   packets to be dropped (two if double buffering is enabled), but this
   seems to be a minor issue, as packet loss can occur when the software is
   not yet ready to process them. Additionally, this solution makes the
   gadget driver compliant with the rule mentioned in the docstring of
   usb_ep_queue().

There may be additional solutions, but from these four, the last one has
been chosen as it seems to be the most appropriate, as it addresses the
"bad" behavior of the driver.

 conversion in ucsi_init()

The GET_CAPABILITY size is wrong. The definitions for the
command sizes are for bitfieds and therefore in bits, not
bytes.

This fixes an issue that prevents the interface from being
registered with UCSI versions older than 2.0 because the
command size exceeds the MESSAGE_IN field size.

Subject: [PATCH 2045/2948] usb: misc: ljca: set small runtime autosuspend
 delay

On some Lenovo platforms, the patch works around problems with ov2740
sensor initialization, which manifest themself like below:

[    4.540476] ov2740 i2c-INT3474:01: error -EIO: failed to find sensor
[    4.542066] ov2740 i2c-INT3474:01: probe with driver ov2740 failed with error -5

or

[    7.742633] ov2740 i2c-INT3474:01: chip id mismatch: 2740 != 0
[    7.742638] ov2740 i2c-INT3474:01: error -ENXIO: failed to find sensor

and also by random failures of video stream start.

Issue can be reproduced by this script:

n=0
k=0
while [ $n -lt 50 ] ; do
	sudo modprobe -r ov2740
	sleep `expr $RANDOM % 5`
	sudo modprobe ov2740
	if media-ctl -p  | grep -q ov2740 ; then
		let k++
	fi
	let n++
done
echo Success rate $k/$n

Without the patch, success rate is approximately 15 or 50 tries.
With the patch it does not fail.

This problem is some hardware or firmware malfunction, that can not be
easy debug and fix. While setting small autosuspend delay is not perfect
workaround as user can configure it to any value, it will prevent
the failures by default.

Additionally setting small autosuspend delay should have positive effect
on power consumption as for most ljca workloads device is used for just
a few milliseconds flowed by long periods of at least 100ms of inactivity
(usually more).

 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/firmware to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

Subject: [PATCH 2052/2948] driver core: class: Correct WARN() message in APIs
 class_(for_each|find)_device()

For both API class_for_each_device(const struct class *class, ...) and
class_find_device(const struct class *class, ...), their WARN() messages
prompt @class was not initialized when suffer class_to_subsys(@class)
error, but the error actually means @class was not registered, so these
warning messages are not accurate.

Fix by replacing term initialized with registered within these messages.

Subject: [PATCH 2054/2948] um: move thread info into task

This selects the THREAD_INFO_IN_TASK option for UM and changes the way
that the current task is discovered. This is trivial though, as UML
already tracks the current task in cpu_tasks[] and this can be used to
retrieve it.

Also remove the signal handler code that copies the thread information
into the IRQ stack. It is obsolete now, which also means that the
mentioned race condition cannot happen anymore.

- * These two functions make sure the rest of the kernel won't be too
- * upset by being on a different stack.  The IRQ stack has a
- * thread_info structure at the bottom so that current et al continue
- * to work.
- *
- * to_irq_stack copies the current task's thread_info to the IRQ stack

- * signals with sigprocmask, SA_DEFER, or sa_mask, so a second signal
- * could arrive while a previous one is still setting up the
- * thread_info.
- *
- * There are three cases -
- *     The first interrupt on the stack - sets up the thread_info and
- * handles the interrupt
- *     A nested interrupt interrupting the copying of the thread_info -
- * can't handle the interrupt, as the stack is in an unknown state
- *     A nested interrupt not interrupting the copying of the
- * thread_info - doesn't do any setup, just handles the interrupt
- *
- * The first job is to figure out whether we interrupted stack setup.
- * This is done by xchging the signal mask with thread_info->pending.
- * If the value that comes back is zero, then there is no setup in
- * progress, and the interrupt can be handled.  If the value is
- * non-zero, then there is stack setup in progress.  In order to have
- * the interrupt handled, we leave our signal in the mask, and it will
- * be handled by the upper handler after it has set up the stack.
- *
- * Next is to figure out whether we are the outer handler or a nested
- * one.  As part of setting up the stack, thread_info->real_thread is

Subject: [PATCH 2056/2948] rtc: support for the Amlogic on-chip RTC

This is the third amlogic driver. The RTC hardware of A4 SoC is different
from the previous one. This RTC hardware includes a timing function and
an alarm function. But the existing has only timing function, alarm
function is using the system clock to implement a virtual alarm. Add
the RTC driver to support it.

Subject: [PATCH 2060/2948] ARM: 9423/1: vfp: Provide vfp_state_hold() for VFP
 locking.

kernel_neon_begin() uses local_bh_disable() to ensure exclusive access
to the VFP unit. This is broken on PREEMPT_RT because a BH disabled
section remains preemptible on PREEMPT_RT.

Introduce vfp_state_hold() which uses local_bh_disable() and
preempt_disable() on PREEMPT_RT. Since softirqs are processed always in
thread context, disabling preemption is enough to ensure that the
current context won't get interrupted by something that is using the
VFP. Use it in kernel_neon_begin().

Subject: [PATCH 2061/2948] ARM: 9424/1: vfp: Use vfp_state_hold() in
 vfp_sync_hwstate().

vfp_sync_hwstate() uses preempt_disable() followed by local_bh_disable()
to ensure that it won't get interrupted while checking the VFP state.
This harms PREEMPT_RT because softirq handling can get preempted and
local_bh_disable() synchronizes the related section with a sleeping lock
which does not work with disabled preemption.

Use the vfp_state_hold() to synchronize the access.

 vfp_support_entry().

vfp_entry() is invoked from exception handler and is fully preemptible.
It uses local_bh_disable() to remain uninterrupted while checking the
VFP state.
This is not working on PREEMPT_RT because local_bh_disable()
synchronizes the relevant section but the context remains fully
preemptible.

Use vfp_state_hold() for uninterrupted access.

Subject: [PATCH 2065/2948] rust: warn on bindgen < 0.69.5 and libclang >= 19.1

When testing a `clang` upgrade with Rust Binder, Alice encountered [1] a
build failure caused by `bindgen` not translating some symbols related to
tracepoints. This was caused by commit 2e770edd8ce1 ("[libclang] Compute
the right spelling location") changing the behavior of a function exposed
by `libclang`. `bindgen` fixed the regression in commit 600f63895f73
("Use clang_getFileLocation instead of clang_getSpellingLocation").

However, the regression fix is only available in `bindgen` versions
0.69.5 or later (it was backported for 0.69.x). This means that when
older bindgen versions are used with new versions of `libclang`, `bindgen`
may do the wrong thing, which could lead to a build failure.

Alice encountered the bug with some header files related to tracepoints,
but it could also cause build failures in other circumstances. Thus,
always emit a warning when using an old `bindgen` with a new `libclang`
so that other people do not have to spend time chasing down the same
bug.

However, testing just the version is inconvenient, since distributions
do patch their packages without changing the version, so I reduced the
issue into the following piece of code that can trigger the issue:

    #define F(x) int x##x
    F(foo);

In particular, an unpatched `bindgen` will ignore the macro expansion
and thus not provide a declaration for the exported `int`.

Thus add a build test to `rust_is_available.sh` using the code above
(that is only triggered if the versions appear to be affected), following
what we did for the 0.66.x issue.

Moreover, I checked the status in the major distributions we have
instructions for:

  - Fedora 41 was affected but is now OK, since it now ships `bindgen`
    0.69.5.

    Thanks Ben for the quick reply on the updates that were ongoing.

    Fedora 40 and earlier are OK (older `libclang`, and they also now
    carry `bindgen` 0.69.5).

  - Debian Sid was affected but is now OK, since they now ship a patched
    `bindgen` binary (0.66.1-7+b3). The issue was reported to Debian by
    email and then as a bug report [2].

    Thanks NoisyCoil and Matthias for the quick replies. NoisyCoil handled
    the needed updates. Debian may upgrade to `bindgen` 0.70.x, too.

    Debian Testing is OK (older `libclang` so far).

  - Ubuntu non-LTS (oracular) is affected. The issue was reported to Ubuntu
    by email and then as a bug report [3].

    Ubuntu LTS is not affected (older `libclang` so far).

  - Arch Linux, Gentoo Linux and openSUSE should be OK (newer `bindgen` is
    provided). Nix as well (older `libclang` so far).

This issue was also added to our "live list" that tracks issues around
distributions [4].

Subject: [PATCH 2066/2948] hisi_acc_vfio_pci: extract public functions for
 container_of

In the current driver, vdev is obtained from struct
hisi_acc_vf_core_device through the container_of function.
This method is used in many places in the driver. In order to
reduce this repetitive operation, It was extracted into
a public function.

Subject: [PATCH 2069/2948] vdpa/mlx5: Fix suboptimal range on iotlb iteration

The starting iova address to iterate iotlb map entry within a range
was set to an irrelevant value when passing to the itree_next()
iterator, although luckily it doesn't affect the outcome of finding
out the granule of the smallest iotlb map size. Fix the code to make
it consistent with the following for-loop.

It is used for testing in tools/virtio/vringh_test.c.
If vring_new_virtqueue supports packed vring, we can add support for
packed vring to vringh and test it.

ops->set_vq_affinity is non-null. Hence the call to create_affinity_masks
does not need to check for desc being non-null is redundant when
has_affinity is true, so it can be removed as well as the now unused
default_affd.

Subject: [PATCH 2076/2948] usb: dwc3: gadget: Add missing check for single
 port RAM in TxFIFO resizing logic

The existing implementation of the TxFIFO resizing logic only supports
scenarios where more than one port RAM is used. However, there is a need
to resize the TxFIFO in USB2.0-only mode where only a single port RAM is
available. This commit introduces the necessary changes to support
TxFIFO resizing in such scenarios by adding a missing check for single
port RAM.

This fix addresses certain platform configurations where the existing
TxFIFO resizing logic does not work properly due to the absence of
support for single port RAM. By adding this missing check, we ensure
that the TxFIFO resizing logic works correctly in all scenarios,
including those with a single port RAM.

Subject: [PATCH 2080/2948] ARM: 9429/1: ioremap: Sync PGDs for VMALLOC shadow

When sync:ing the VMALLOC area to other CPUs, make sure to also
sync the KASAN shadow memory for the VMALLOC area, so that we
don't get stale entries for the shadow memory in the top level PGD.

Since we are now copying PGDs in two instances, create a helper
function named memcpy_pgd() to do the actual copying, and
create a helper to map the addresses of VMALLOC_START and
VMALLOC_END into the corresponding shadow memory.

Subject: [PATCH 2082/2948] ARM: 9431/1: mm: Pair atomic_set_release() with
 _read_acquire()

The code for syncing vmalloc memory PGD pointers is using
atomic_read() in pair with atomic_set_release() but the
proper pairing is atomic_read_acquire() paired with
atomic_set_release().

This is done to clearly instruct the compiler to not
reorder the memcpy() or similar calls inside the section
so that we do not observe changes to init_mm. memcpy()
calls should be identified by the compiler as having
unpredictable side effects, but let's try to be on the
safe side.

Subject: [PATCH 2085/2948] pinctrl: cy8c95x0: use flexible sleeping in reset
 function

The device reset assert and deassert length was created by usleep_range()
but that does not ensure optimal handling of all the different values from
device tree properties. By switching to the new flexible sleeping helper
function, fsleep(), the correct delay function is called depending on
delay length, e.g. udelay(), usleep_range() or msleep().

While at it, move out GPIO consumer name setting of the reset conditional,
the all necessary checks are already done there, so logically that call is
not related to the reset sequence.

Subject: [PATCH 2087/2948] pinctrl: cy8c95x0: embed iterator to the for-loop

When we iterate through nports the iterator variable is effectively
being not used outside of the loop. Make it clear by moving its definition
into the for-loop. This makes code cleaner as well.

Subject: [PATCH 2088/2948] pinctrl: cy8c95x0: remove unneeded goto labels

In some cases the code uses goto labels to just return an error code.
Replace those with direct return:s and drop unneeded goto labels.

Subject: [PATCH 2099/2948] tty: ldsic: fix tty_ldisc_autoload sysctl's
 proc_handler

Commit 7c0cca7c847e ("tty: ldisc: add sysctl to prevent autoloading of
ldiscs") introduces the tty_ldisc_autoload sysctl with the wrong
proc_handler. .extra1 and .extra2 parameters are set to avoid other values
thant SYSCTL_ZERO or SYSCTL_ONE to be set but proc_dointvec do not uses
them.

This commit fixes this by using proc_dointvec_minmax instead of
proc_dointvec.

Subject: [PATCH 2100/2948] serial: amba-pl011: Fix RX stall when DMA is used

Function pl011_throttle_rx() calls pl011_stop_rx() to disable RX, which
also disables the RX DMA by clearing the RXDMAE bit of the DMACR
register. However, to properly unthrottle RX when DMA is used, the
function pl011_unthrottle_rx() is expected to set the RXDMAE bit of
the DMACR register, which it currently lacks. This causes RX to stall
after the throttle API is called.

Set RXDMAE bit in the DMACR register while unthrottling RX if RX DMA is
used.

 phy-names property is absent in DTS
MIME-Version: 1.0

The "phy-names" property is optional, so the message indicating its
absence during the probe should be of "info" severity rather than
"error" severity.

it is inadvisable to perform pointer arithmetic or address-taking on a

Introduce the nd_dax_devinit() function to enhance the code's logic and

Subject: [PATCH 2112/2948] perf disasm: Allow configuring what disassemblers
 to use

The perf tools annotation code used for a long time parsing the output
of binutils's objdump (or its reimplementations, like llvm's) to then
parse and augment it with samples, allow navigation, etc.

More recently disassemblers from the capstone and llvm (libraries, not
parsing the output of tools using those libraries to mimic binutils's
objdump output) were introduced.

So when all those methods are available, there is a static preference
for a series of attempts of disassembling a binary, with the 'llvm,
capstone, objdump' sequence being hard coded.

This patch allows users to change that sequence, specifying via a 'perf
config' 'annotate.disassemblers' entry which and in what order
disassemblers should be attempted.

As alluded to in the comments in the source code of this series, this
flexibility is useful for users and developers alike, elliminating the
requirement to rebuild the tool with some specific set of libraries to
see how the output of disassembling would be for one of these methods.

This patch makes a minor change that removes a redundant variable
assignment. The assignment before the for loop is duplicated by the
initialization within the loop header.

Subject: [PATCH 2116/2948] libsubcmd: Move va_end() before exit

This patch makes a minor adjustment by moving the va_end call before
exit. Since the exit() function terminates the program, any code
after exit(128) (i.e., va_end(params)) is unreachable and thus not
executed. Placing va_end before exit ensures that the va_list is
properly cleaned up.

Subject: [PATCH 2118/2948] PCI: starfive: Enable controller runtime PM before
 probing host bridge

A PCI controller device, e.g., StarFive, is parent to PCI host bridge
device. We must enable runtime PM of the controller before enabling runtime
PM of the host bridge, which will happen in pci_host_probe(), to avoid this
warning:

  pcie-starfive 940000000.pcie: Enabling runtime PM for inactive device with active children

Fix this issue by enabling StarFive controller device's runtime PM before
calling pci_host_probe() in plda_pcie_host_init().

Subject: [PATCH 2119/2948] PCI: Enable runtime PM of the host bridge

The controller driver is the parent device of the PCIe host bridge,
PCI-PCI bridge and PCIe endpoint as shown below.

  PCIe controller (Top level parent & parent of host bridge)
                  |
                  v
  PCIe Host bridge (Parent of PCI-PCI bridge)
                  |
                  v
  PCI-PCI bridge (Parent of endpoint driver)
                  |
                  v
          PCIe endpoint driver

Now, when the controller device goes to runtime suspend, PM framework will
check the runtime PM state of the child device (host bridge) and will find
it to be disabled. So it will allow the parent (controller device) to go to
runtime suspend. Only if the child device's state was 'active' it will
prevent the parent to get suspended.

It is a property of the runtime PM framework that it can only follow
continuous dependency chains.  That is, if there is a device with runtime
PM disabled in a dependency chain, runtime PM cannot be enabled for devices
below it and above it in that chain both at the same time.

Since runtime PM is disabled for host bridge, the state of the child
devices under the host bridge is not taken into account by PM framework for
the top level parent, PCIe controller. So the PM framework allows the
controller driver to enter runtime PM irrespective of the state of the
devices under the host bridge. And this causes the topology breakage and
also possible PM issues like controller driver going to runtime suspend
while the endpoint driver is doing transfers.

Because of the above, in order to enable runtime PM for a PCIe controller
device, one needs to ensure that runtime PM is enabled for all devices in
every dependency chain between it and any PCIe endpoint (as runtime PM is
enabled for PCIe endpoints).

This means that runtime PM needs to be enabled for the host bridge device,
which is present in all of these dependency chains.

After this change, the host bridge device will be runtime-suspended by the
runtime PM framework automatically after suspending its last child and it
will be runtime-resumed automatically before resuming its first child which
will allow the runtime PM framework to track dependencies between the host
bridge device and all of its descendants.

The PM framework expects parent runtime PM to be enabled before enabling
runtime PM of the child. Ensure pm_runtime_enable() is called for the
controller drivers before calling pci_host_probe().

Subject: [PATCH 2120/2948] hisi_acc_vfio_pci: register debugfs for hisilicon
 migration driver

On the debugfs framework of VFIO, if the CONFIG_VFIO_DEBUGFS macro is
enabled, the debug function is registered for the live migration driver
of the HiSilicon accelerator device.

After registering the HiSilicon accelerator device on the debugfs
framework of live migration of vfio, a directory file "hisi_acc"
of debugfs is created, and then three debug function files are
created in this directory:

   vfio

                 +--migf_data
                 +--cmd_state

dev_data file: read device data that needs to be migrated from the
current device in real time
migf_data file: read the migration data of the last live migration
from the current driver.
cmd_state: used to get the cmd channel state for the device.

When accessing debugfs, user can obtain the most recent status data
of the device through the "dev_data" file. It can read recent
complete status data of the device. If the current device is being
migrated, it will wait for it to complete.
The data for the last completed migration function will be stored
in debug_migf. Users can read it via "migf_data".

Subject: [PATCH 2123/2948] virtio: Extend the admin command to include the
 result size

Extend the admin command by incorporating a result size field.

This allows higher layers to determine the actual result size from the
backend when this information is not included in the result_sg.

The additional information introduced here will be used in subsequent
patches of this series.

Subject: [PATCH 2124/2948] virtio: Manage device and driver capabilities via
 the admin commands

Manage device and driver capabilities via the admin commands.

The device exposes its supported features and resource object limits via
an administrative command called VIRTIO_ADMIN_CMD_CAP_ID_LIST_QUERY,
using the 'self group type.'

Each capability is identified by a unique ID, and the driver
communicates the functionality and resource limits it plans to utilize.

The capability VIRTIO_DEV_PARTS_CAP specifically represents the device's
parts resource object limit.

Manage the device's parts resource object ID using a common IDA for both
get and set operations.

Subject: [PATCH 2125/2948] virtio-pci: Introduce APIs to execute device parts
 admin commands

Introduce APIs to handle the execution of device parts admin commands.

These APIs cover functionalities such as mode setting, object creation
and destruction, and operations like parts get/set and metadata
retrieval.

These APIs will be utilized in upcoming patches within this series.

Subject: [PATCH 2126/2948] PCI: Add 'reset_subordinate' to reset hierarchy
 below bridge

The "bus" and "cxl_bus" reset methods reset a device by asserting Secondary
Bus Reset on the bridge leading to the device.  These only work if the
device is the only device below the bridge.

Add a sysfs 'reset_subordinate' attribute on bridges that can assert
Secondary Bus Reset regardless of how many devices are below the bridge.

This resets all the devices below a bridge in a single command, including
the locking and config space save/restore that reset methods normally do.

This may be the only way to reset devices that don't support other reset
methods (ACPI, FLR, PM reset, etc).

Subject: [PATCH 2127/2948] PCI: Warn if a running device is unaware of reset

If a reset is issued to a running device with a driver that didn't register
the notification callbacks, the driver may be unaware of this event and
have an inconsistent view of the device's state. Log a warning of this
event because there's nothing else indicating the event occured, which
could be confusing when debugging such situations.

Subject: [PATCH 2128/2948] vfio/virtio: Add support for the basic live
 migration functionality

Add support for basic live migration functionality in VFIO over
virtio-net devices, aligned with the virtio device specification 1.4.

This includes the following VFIO features:
VFIO_MIGRATION_STOP_COPY, VFIO_MIGRATION_P2P.

The implementation registers with the VFIO subsystem using vfio_pci_core
and then incorporates the virtio-specific logic for the migration
process.

The migration follows the definitions in uapi/vfio.h and leverages the
virtio VF-to-PF admin queue command channel for execution device parts
related commands.

Additional Notes:
-----------------
The kernel protocol between the source and target devices contains a
header with metadata, including record size, tag, and flags.

The record size allows the target to recognize and read a complete image
from the source before passing the device part data. This adheres to the
virtio device specification, which mandates that partial device parts
cannot be supplied.

The tag and flags serve as placeholders for future extensions of the
kernel protocol between the source and target, ensuring backward and
forward compatibility.

Both the source and target comply with the virtio device specification
by using a device part object with a unique ID as part of the migration
process. Since this resource is limited to a maximum of 255, its
lifecycle is confined to periods with an active live migration flow.

According to the virtio specification, a device has only two modes:
RUNNING and STOPPED. As a result, certain VFIO transitions (i.e.,
RUNNING_P2P->STOP, STOP->RUNNING_P2P) are treated as no-ops. When
transitioning to RUNNING_P2P, the device state is set to STOP, and it
will remain STOPPED until the transition out of RUNNING_P2P->RUNNING, at
which point it returns to RUNNING. During transition to STOP, the virtio
device only stops initiating outgoing requests(e.g. DMA, MSIx, etc.) but
still must accept incoming operations.

Subject: [PATCH 2129/2948] vfio/virtio: Add PRE_COPY support for live
 migration

Add PRE_COPY support for live migration.

This functionality may reduce the downtime upon STOP_COPY as of letting
the target machine to get some 'initial data' from the source once the
machine is still in its RUNNING state and let it prepares itself
pre-ahead to get the final STOP_COPY data.

As the Virtio specification does not support reading partial or
incremental device contexts. This means that during the PRE_COPY state,
the vfio-virtio driver reads the full device state.

As the device state can be changed and the benefit is highest when the
pre copy data closely matches the final data we read it in a rate
limiter mode.

This means we avoid reading new data from the device for a specified
time interval after the last read.

With PRE_COPY enabled, we observed a downtime reduction of approximately
70-75% in various scenarios compared to when PRE_COPY was disabled,
while keeping the total migration time nearly the same.

Subject: [PATCH 2130/2948] vfio/virtio: Enable live migration once VIRTIO_PCI
 was configured

Now that the driver supports live migration, only the legacy IO
functionality depends on config VIRTIO_PCI_ADMIN_LEGACY.

As part of that we introduce a bool configuration option as a sub menu
under the driver's main live migration feature named
VIRTIO_VFIO_PCI_ADMIN_LEGACY, to control the legacy IO functionality.

This will let users configuring the kernel, know which features from the
description might be available in the resulting driver.

As of that, move the legacy IO into a separate file to be compiled only
once CONFIG_VIRTIO_VFIO_PCI_ADMIN_LEGACY was configured and let the live
migration depends only on VIRTIO_PCI.

Subject: [PATCH 2131/2948] PCI: hotplug: Add OCTEON PCI hotplug controller
 driver

Add a PCI hotplug controller driver for the OCTEON PCIe device. The OCTEON
PCIe device is a multi-function device where function 0 serves as the PCI
hotplug controller.

There is an out-of-band management console interface to firmware running on
function 0 whereby an administrator can disable functions to save power or
enable them with one of several personalities (virtio-net, virtio-crypto,
NVMe, etc) for the other functions.  Function 0 initiates hotplug events
handled by this driver when the other functions are enabled or disabled.

                 +--------------------------------+
                 |           Root Port            |
                 +--------------------------------+

               |                    |              |            |
               |                    |              |            |
  +---------------------+  +----------------+  +-----+  +----------------+
  |      Function 0     |  |   Function 1   |  | ... |  |   Function 7   |
  | (Hotplug controller)|  | (Hotplug slot) |  |     |  | (Hotplug slot) |
  +---------------------+  +----------------+  +-----+  +----------------+
               |
               |
  +-------------------------+
  |   Controller Firmware   |
  +-------------------------+

The hotplug controller driver enables hotplugging of non-controller
functions within the same device. During probing, the driver removes
the non-controller functions and registers them as PCI hotplug slots.
These slots are added back by the driver, only upon request from the
device firmware.

The controller uses MSI-X interrupts to notify the host of hotplug
events initiated by the OCTEON firmware. Additionally, the driver
allows users to enable or disable individual functions via sysfs slot
entries, as provided by the PCI hotplug framework.

Subject: [PATCH 2133/2948] soundwire: Update the includes on the sdw.h header

There are quite a few things used in the sdw.h header that it relies on
the consumer to include. If something is used directly in the header it
should be included by the header. Update the includes to cover the
missing items, or add forward declarations for things that are only used
as pointers. Whilst making the change also alphabetise the list of
includes.

Subject: [PATCH 2137/2948] USB: make single lock for all usb dynamic id lists

There are a number of places where we accidentally pass in a constant
structure to later cast it off to a dynamic one, and then attempt to
grab a lock on it, which is not a good idea.  To help resolve this, move
the dynamic id lock out of the dynamic id structure for the driver and
into one single lock for all USB dynamic ids.  As this lock should never
have any real contention (it's only every accessed when a device is
added or removed, which is always serialized) there should not be any
difference except for some memory savings.

Note, this just converts the existing use of the dynamic id lock to the
new static lock, there is one place that is accessing the dynamic id
list without grabbing the lock, that will be fixed up in a follow-on
change.

Subject: [PATCH 2138/2948] USB: properly lock dynamic id list when showing an
 id

When walking the list of dynamic ids for a driver, no lock was being
held, which meant that an id could be removed or added while the list
was being iterated.  Fix this up by properly grabing the lock while we
walk the list.

Function ubifs_evict_xattr_inode() is imported by commit 272eda8298dc
("ubifs: Correctly evict xattr inodes") to reclaim xattr inode when
the host inode is deleted.
The xattr inode is evicted in the host inode deleting process since
commit 7959cf3a7506 ("ubifs: journal: Handle xattrs like files").
So the ineffective function ubifs_evict_xattr_inode() can be deleted
safely.

Subject: [PATCH 2141/2948] ubi: wl: Put source PEB into correct list if trying
 locking LEB failed

During wear-leveing work, the source PEB will be moved into scrub list
when source LEB cannot be locked in ubi_eba_copy_leb(), which is wrong
for non-scrub type source PEB. The problem could bring extra and
ineffective wear-leveing jobs, which makes more or less negative effects
for the life time of flash. Specifically, the process is divided 2 steps:
1. wear_leveling_worker // generate false scrub type PEB
     ubi_eba_copy_leb // MOVE_RETRY is returned
       leb_write_trylock // trylock failed
     scrubbing = 1;
     e1 is put into ubi->scrub
2. wear_leveling_worker // schedule false scrub type PEB for wl
     scrubbing = 1
     e1 = rb_entry(rb_first(&ubi->scrub))

The problem can be reproduced easily by running fsstress on a small
UBIFS partition(<64M, simulated by nandsim) for 5~10mins
(CONFIG_MTD_UBI_FASTMAP=y,CONFIG_MTD_UBI_WL_THRESHOLD=50). Following
message is shown:
 ubi0: scrubbed PEB 66 (LEB 0:10), data moved to PEB 165

Since scrub type source PEB has set variable scrubbing as '1', and
variable scrubbing is checked before variable keep, so the problem can
be fixed by setting keep variable as 1 directly if the source LEB cannot
be locked.

Since commit 14072ee33d5a ("ubi: fastmap: Check wl_pool for free peb
before wear leveling"), wear_leveling_worker() won't schedule fm_work
if wear-leveling pool is empty, which could temporarily disable the
wear-leveling until the fastmap is updated(eg. pool becomes empty).
Fix it by scheduling fm_work if wl_pool is empty during wear-leveing.

Subject: [PATCH 2145/2948] ubifs: add support for FS_IOC_GETFSSYSFSPATH

In commit ae8c51175730 ("fs: add FS_IOC_GETFSSYSFSPATH"), a
new fs ioctl was introduced to standardize exporting data from
sysfs across filesystems. The returned path will always be of the
form "$FSTYP/$SYSFS_IDENTIFIER", where the sysfs identifier may
be a UUID or a device name.

The ubifs is a file system based on char device, and the common
method to fill s_sysfs_name (super_set_sysfs_name_bdev) is
unavialable. So in order to support FS_IOC_GETFSSYSFSPATH ioctl,
we fill the s_sysfs_name with ubi_volume_info member which keeps
the format defined in macro UBIFS_DFS_DIR_NAME by using
super_set_sysfs_name_generic.

That's for ubifs, it will output "ubifs/<dev>".

```
$ ./ioctl_getfssysfs_path /mnt/ubifs/testfile
path: ubifs/ubi0_0

$ ls /sys/fs/ubifs/ubi0_0/
errors_crc  errors_magic  errors_node

Subject: [PATCH 2146/2948] USB: make to_usb_driver() use container_of_const()

Turns out that we have some const pointers being passed to
to_usb_driver() but were not catching this.  Change the macro to
properly propagate the const-ness of the pointer so that we will notice
when we try to write to memory that we shouldn't be writing to.

This requires fixing up the usb_match_dynamic_id() function as well,
because it can handle a const * to struct usb_driver.

Subject: [PATCH 2149/2948] ubifs: Correct the total block count by deducting
 journal reservation

Since commit e874dcde1cbf ("ubifs: Reserve one leb for each journal
head while doing budget"), available space is calulated by deducting
reservation for all journal heads. However, the total block count (
which is only used by statfs) is not updated yet, which will cause
the wrong displaying for used space(total - available).
Fix it by deducting reservation for all journal heads from total
block count.

Subject: [PATCH 2151/2948] ubi: wl: Close down wear-leveling before nand is
 suspended
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If a reboot/shutdown signal with double force (-ff) is triggered when
the erase worker or wear-leveling worker function runs we may end up in
a race condition since the MTD device gets a reboot notification and
suspends the nand flash before the erase or wear-leveling is done. This
will reject all accesses to the flash with -EBUSY.

Sequence for the erase worker function:

   systemctl reboot -ff           ubi_thread

                                do_work
 __do_sys_reboot
   blocking_notifier_call_chain
     mtd_reboot_notifier
       nand_shutdown
         nand_suspend
                                  __erase_worker
                                    ubi_sync_erase
                                      mtd_erase
                                        nand_erase_nand

                                          # Blocked by suspended chip
                                          nand_get_device
                                            => EBUSY

Similar sequence for the wear-leveling function:

   systemctl reboot -ff           ubi_thread

                                do_work
 __do_sys_reboot
   blocking_notifier_call_chain
     mtd_reboot_notifier
       nand_shutdown
         nand_suspend

 ubifs_purge_xattrs()

An iput(xino) call was immediately used after a return value check
for a remove_xattr() call in this function implementation.
Thus call such a function only once instead directly before the check.

This issue was transformed by using the Coccinelle software.

Fix an unwind issue in mlx5vf_add_migration_pages().

If a set of pages is allocated but fails to be added to the SG table,
they need to be freed to prevent a memory leak.

Any pages successfully added to the SG table will be freed as part of
mlx5vf_free_data_buffer().

Fix unwind flows in mlx5vf_pci_save_device_data() and

To ensure mlx5vf_release_file() functions correctly, move the

potential unwind flow, as these fields may be accessed within
mlx5vf_release_file().

Subject: [PATCH 2157/2948] ubi: fastmap: Fix duplicate slab cache names while
 attaching

Since commit 4c39529663b9 ("slab: Warn on duplicate cache names when
DEBUG_VM=y"), the duplicate slab cache names can be detected and a
kernel WARNING is thrown out.
In UBI fast attaching process, alloc_ai() could be invoked twice
with the same slab cache name 'ubi_aeb_slab_cache', which will trigger
following warning messages:
 kmem_cache of name 'ubi_aeb_slab_cache' already exists

The problem could be easily reproduced by loading UBI device by fastmap
with CONFIG_DEBUG_VM=y.
Fix it by using different slab names for alloc_ai() callers.

Subject: [PATCH 2158/2948] ubifs: authentication: Fix use-after-free in
 ubifs_tnc_end_commit

After an insertion in TNC, the tree might split and cause a node to
change its `znode->parent`. A further deletion of other nodes in the
tree (which also could free the nodes), the aforementioned node's
`znode->cparent` could still point to a freed node. This
`znode->cparent` may not be updated when getting nodes to commit in
`ubifs_tnc_start_commit()`. This could then trigger a use-after-free
when accessing the `znode->cparent` in `write_index()` in
`ubifs_tnc_end_commit()`.

This can be triggered by running

  rm -f /etc/test-file.bin
  dd if=/dev/urandom of=/etc/test-file.bin bs=1M count=60 conv=fsync

in a loop, and with `CONFIG_UBIFS_FS_AUTHENTICATION`. KASAN then
reports:

The offending `memcpy()` in `ubifs_copy_hash()` has a use-after-free
when a node becomes root in TNC but still has a `cparent` to an already
freed node. More specifically, consider the following TNC:

         zroot
         /
        /
      zp1
      /
     /
    zn

Inserting a new node `zn_new` with a key smaller then `zn` will trigger
a split in `tnc_insert()` if `zp1` is full:

         zroot
         /   \
        /     \
      zp1     zp2
      /         \
     /           \
  zn_new          zn

`zn->parent` has now been moved to `zp2`, *but* `zn->cparent` still
points to `zp1`.

Now, consider a removal of all the nodes _except_ `zn`. Just when
`tnc_delete()` is about to delete `zroot` and `zp2`:

         zroot
             \
              \
              zp2
                \
                 \
                 zn

`zroot` and `zp2` get freed and the tree collapses:

           zn

`zn` now becomes the new `zroot`.

`get_znodes_to_commit()` will now only find `zn`, the new `zroot`, and
`write_index()` will check its `znode->cparent` that wrongly points to
the already freed `zp1`. `ubifs_copy_hash()` thus gets wrongly called
with `znode->cparent->zbranch[znode->iip].hash` that triggers the
use-after-free!

Fix this by explicitly setting `znode->cparent` to `NULL` in
`get_znodes_to_commit()` for the root node. The search for the dirty
nodes is bottom-up in the tree. Thus, when `find_next_dirty(znode)`
returns NULL, the current `znode` _is_ the root node. Add an assert for
this.

Subject: [PATCH 2160/2948] mtd: ubi: remove redundant check on bytes_left at
 end of function

In function ubi_nvmem_reg_read the while-loop can only be exiting
of bytes_left is zero or an error has occurred. There is an exit
return path if an error occurs, so the bytes_left can only be
zero after that point. Hence the check for a non-zero bytes_left
at the end of the function is redundant and can be removed. Remove
the check and just return 0.

Subject: [PATCH 2162/2948] jffs2: fix use of uninitialized variable

When building the kernel with -Wmaybe-uninitialized, the compiler
reports this warning:

In function 'jffs2_mark_erased_block',
    inlined from 'jffs2_erase_pending_blocks' at fs/jffs2/erase.c:116:4:
fs/jffs2/erase.c:474:9: warning: 'bad_offset' may be used uninitialized [-Wmaybe-uninitialized]
  474 |         jffs2_erase_failed(c, jeb, bad_offset);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
fs/jffs2/erase.c: In function 'jffs2_erase_pending_blocks':
fs/jffs2/erase.c:402:18: note: 'bad_offset' was declared here
  402 |         uint32_t bad_offset;
      |                  ^~~~~~~~~~

When mtd->point() is used, jffs2_erase_pending_blocks can return -EIO
without initializing bad_offset, which is later used at the filebad
label in jffs2_mark_erased_block.
Fix it by initializing this variable.

      perf trace: Migrate BPF augmentation to use a skeleton

  perf $ ./perf trace -e write --max-events=10 & echo #!
  [1] 1808653
  perf $
       0.000 ( 0.010 ms): :1808671/1808671 write(fd: 1, buf: 0x6003f5b26fc0, count: 11) = 11
       0.162 (         ): perf/1808653 write(fd: 2, buf: 0x7fffc2174e50, count: 11)     ...
       0.174 (         ): perf/1808653 write(fd: 2, buf: 0x74ce21804563, count: 1)      ...
       0.184 (         ): perf/1808653 write(fd: 2, buf: 0x57b936589052, count: 5)

The feedback loop is there.

Keep it running, look into the bpf map:

  perf $ bpftool map | grep pids_filtered
  10675: hash  name pids_filtered  flags 0x0

  perf $ bpftool map dump id 10675
  []

The map is empty.

Now, this commit:

  64917f4df048a064 ("perf trace: Use heuristic when deciding if a syscall tracepoint "const char *" field is really a string")

Temporarily fixed the feedback loop for perf trace -e write, that's
because before using the heuristic, write is hooked to sys_enter_openat:

  perf $ git log
  commit 83a0943b1870944612a8aa0049f910826ebfd4f7 (HEAD)
  Author: Arnaldo Carvalho de Melo <acme@redhat.com>
  Date:   Thu Aug 17 12:11:51 2023 -0300

      perf trace: Use the augmented_raw_syscall BPF skel only for tracing syscalls

  perf $ ./perf trace -e write --max-events=10 -v 2>&1 | grep Reusing
  Reusing "openat" BPF sys_enter augmenter for "write"

And after the heuristic fix, it's unaugmented:

  perf $ git log
  commit 64917f4df048a0649ea7901c2321f020e71e6f24 (HEAD)
  Author: Arnaldo Carvalho de Melo <acme@redhat.com>
  Date:   Thu Aug 17 15:14:21 2023 -0300

      perf trace: Use heuristic when deciding if a syscall tracepoint "const char *" field is really a string

  perf $ ./perf trace -e write --max-events=10 -v 2>&1 | grep Reusing
  perf $

After using the heuristic, write is hooked to syscall_unaugmented, which
returns 1.

  SEC("tp/raw_syscalls/sys_enter")
  int syscall_unaugmented(struct syscall_enter_args *args)
  {
  	return 1;
  }

If the BPF program returns 1, the tracepoint filter will filter it
(since the tracepoint filter for perf is correctly set), but before the
heuristic, when it was hooked to a sys_enter_openat(), which is a BPF
program that calls bpf_perf_event_output() and writes to the buffer, it
didn't get filtered, thus creating feedback loop. So switching write to
unaugmented accidentally fixed the problem.

But some syscalls are not so lucky, for example newfstatat:
perf $ ./perf trace -e newfstatat --max-events=100 & echo #!
[1] 2166948

   457.718 (         ): perf/2166948 newfstatat(dfd: CWD, filename: "/proc/self/ns/mnt", statbuf: 0x7fff0132a9f0) ...
   457.749 (         ): perf/2166948 newfstatat(dfd: CWD, filename: "/proc/2166950/ns/mnt", statbuf: 0x7fff0132aa80) ...
   457.962 (         ): perf/2166948 newfstatat(dfd: CWD, filename: "/proc/self/ns/mnt", statbuf: 0x7fff0132a9f0) ...

Currently, write is augmented by the new BTF general augmenter (which
calls bpf_perf_event_output()). The problem, which luckily got fixed,
resurfaced, and that’s how it was discovered.

The rtime decompression routine does not fully check bounds during the

 line range

With --lines option, if perf-probe fails to find the specified line, it
warns as "Debuginfo analysis failed." but this misleads user as the
debuginfo is broken.

Fix this message to "Specified source line(LINESPEC) is not found." so
that user can understand the error correctly.

Subject: [PATCH 2171/2948] perf string: Add strpbrk_esq() and strdup_esq() for
 escape and quote

strpbrk_esq() and strdup_esq() are new variants for strpbrk() and
strdup() which handles escaped characters and quoted strings.

- strpbrk_esq() searches specified set of characters but ignores the
  escaped characters and quoted strings.
  e.g. strpbrk_esq("'quote\d' \queue quiz", "qd") returns "quiz".

- strdup_esq() duplicates string but removes backslash and quotes which
  is used for quotation. It also keeps the string (including backslash)
  in the quoted part.
  e.g. strdup_esq("'quote\d' \queue quiz") returns "quote\d queue quiz".

The (single, double) quotes in the quoted part should be escaped by
backslash. In this case, strdup_esq() removes that backslash.
The same quotes must be paired. If you use double quotation, you need
to use the double quotation to close the quoted part.

In non-C languages, it is possible to have ':' in the function names.

It is possible to escape it with backslashes, but if there are too many
backslashes, it is annoying.

This introduce quotation marks (`"` or `'`) support.

For example, without quotes, we have to pass it as below

  $ perf probe -x cro3 -L "cro3\:\:cmd\:\:servo\:\:run_show"
  <run_show@/work/cro3/src/cmd/servo.rs:0>
        0  fn run_show(args: &ArgsShow) -> Result<()> {
        1      let list = ServoList::discover()?;
        2      let s = list.find_by_serial(&args.servo)?;
        3      if args.json {
        4          println!("{s}");

With quotes, we can more naturally write the function name as below;

  $ perf probe -x cro3 -L \"cro3::cmd::servo::run_show\"
  <run_show@/work/cro3/src/cmd/servo.rs:0>
        0  fn run_show(args: &ArgsShow) -> Result<()> {
        1      let list = ServoList::discover()?;
        2      let s = list.find_by_serial(&args.servo)?;
        3      if args.json {
        4          println!("{s}");

Subject: [PATCH 2173/2948] perf trace: Do not lose last events in a race

If a perf trace event selector specifies a maximum number of events to output
(i.e., "/nr=N/" syntax), the event printing handler, trace__event_handler,
disables the event selector after the maximum number events are
printed.

Furthermore, trace__event_handler checked if the event selector was
disabled before doing any work. This avoided exceeding the maximum
number of events to print if more events were in the buffer before the
selector was disabled.

However, the event selector can be disabled for reasons other than
exceeding the maximum number of events. In particular, when the traced
subprocess exits, the main loop disables all event selectors. This meant
the last events of a traced subprocess might be lost to the printing
handler's short-circuiting logic.

This nondeterministic problem could be seen by running the following many times:

  $ perf trace -e syscalls:sys_enter_exit_group true

trace__event_handler should simply check for exceeding the maximum number of
events to print rather than the state of the event selector.

Fixes: a9c5e6c1e9bff42c ("perf trace: Introduce per-event maximum number of events property")

Subject: [PATCH 2174/2948] perf trace: Avoid garbage when not printing a
 syscall's arguments

syscall__scnprintf_args may not place anything in the output buffer
(e.g., because the arguments are all zero). If that happened in
trace__fprintf_sys_enter, its fprintf would receive an unitialized
buffer leading to garbage output.

Fix the problem by passing the (possibly zero) bounds of the argument
buffer to the output fprintf.

Subject: [PATCH 2179/2948] MIPS: mobileye: eyeq5: use OLB as provider for
 fixed factor clocks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change the structure of the clock tree: rather than individual
devicetree nodes registering each fixed factor clock derived from OLB
PLLs, have the OLB node provide the necessary clocks.

Remove eyeq5-clocks.dtsi and move the three remaining "fixed-clock"s to
the main eyeq5.dtsi file.

 remove fixed clocks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change the declaration of clocks: remove all fixed clocks and declare
system-controllers (OLB) as clock providers.

Remove eyeq6h-fixed-clocks.dtsi and move the crystal clock to the main
eyeq6h.dtsi file.

Subject: [PATCH 2181/2948] fs: prepare for "explicit connectable" file handles

We would like to use the high 16bit of the handle_type field to encode
file handle traits, such as "connectable".

In preparation for this change, make sure that filesystems do not return
a handle_type value with upper bits set and that the open_by_handle_at(2)
syscall rejects these handle types.

Subject: [PATCH 2182/2948] fs: name_to_handle_at() support for "explicit
 connectable" file handles

nfsd encodes "connectable" file handles for the subtree_check feature,
which can be resolved to an open file with a connected path.
So far, userspace nfs server could not make use of this functionality.

Introduce a new flag AT_HANDLE_CONNECTABLE to name_to_handle_at(2).
When used, the encoded file handle is "explicitly connectable".

The "explicitly connectable" file handle sets bits in the high 16bit of
the handle_type field, so open_by_handle_at(2) will know that it needs
to open a file with a connected path.

old kernels will now recognize the handle_type with high bits set,
so "explicitly connectable" file handles cannot be decoded by
open_by_handle_at(2) on old kernels.

The flag AT_HANDLE_CONNECTABLE is not allowed together with either
AT_HANDLE_FID or AT_EMPTY_PATH.

Subject: [PATCH 2183/2948] fs: open_by_handle_at() support for decoding
 "explicit connectable" file handles

Teach open_by_handle_at(2) about the type format of "explicit connectable"
file handles that were created using the AT_HANDLE_CONNECTABLE flag to
name_to_handle_at(2).

When decoding an "explicit connectable" file handles, name_to_handle_at(2)
should fail if it cannot open a "connected" fd with known path, which is
accessible (to capable user) from mount fd path.

Note that this does not check if the path is accessible to the calling
user, just that it is accessible wrt the mount namesapce, so if there
is no "connected" alias, or if parts of the path are hidden in the
mount namespace, open_by_handle_at(2) will return -ESTALE.

Subject: [PATCH 2184/2948] ecryptfs: Factor out mount option validation

Under the new mount API, mount options are parsed one at a time.
Any validation that examines multiple options must be done after parsing
is complete, so factor out a ecryptfs_validate_options() which can be
called separately.

To facilitate this, temporarily move the local variables that tracked
whether various options have been set in the parsing function, into the
ecryptfs_mount_crypt_stat structure so that they can be examined later.

These will be moved to a more ephemeral struct in the mount api conversion
patch to follow.

Subject: [PATCH 2187/2948] perf test shell trace_exit_race: Show what went
 wrong in verbose mode

If it fails we need to check what was the reason, what were the lines
that didn't match the expected format, so:

  root@number:~# perf test -v "trace exit race"
  --- start ---
  test child forked, pid 2028724
  Lines not matching the expected regexp: ' +[0-9]+\.[0-9]+ +true/[0-9]+ syscalls:sys_enter_exit_group\(\)$':
       0.000 :2028750/2028750 syscalls:sys_enter_exit_group()
  ---- end(-1) ----
  110: perf trace exit race                                            : FAILED!
  root@number:~#

In this case we're not resolving the process COMM for some reason and
fallback to printing just the pid/tid, this will be fixed in a followup
patch.

Howard Chu spotted a problem with single code surrounding a regexp, that
made the test always fail, but since there were some failures when I
tested (COMM not being resolved in some of the results) the end inverse
grep would show some lines and thus didn't notice the single quote
problem.

He also provided a patch to test if less than the number of expected
matches took place but all of them with the expected output, in which
case the inverse grep wouldn't show anything, confusing the tester.

Subject: [PATCH 2189/2948] PCI: of_property: Assign PCI instead of CPU bus
 address to dynamic PCI nodes

When populating "ranges" property for a PCI bridge or endpoint,
of_pci_prop_ranges() incorrectly uses the CPU address of the resource.  In
such PCI nodes, the window should instead be in PCI address space. Call
pci_bus_address() on the resource in order to obtain the PCI bus address.

Subject: [PATCH 2190/2948] sysfs: attribute_group: allow registration of const
 bin_attribute
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To be able to constify instances of struct bin_attribute it has to be
possible to add them to string attribute_group.
The current type of the bin_attrs member however is not compatible with
that.
Introduce a union that allows registration of both const and non-const
attributes to enable a piecewise transition.
As both union member types are compatible no logic needs to be adapted.

Technically it is now possible register a const struct
bin_attribute and receive it as mutable pointer in the callbacks.
This is a soundness issue.
But this same soundness issue already exists today in
sysfs_create_bin_file().
Also the struct definition and callback implementation are always
closely linked and are meant to be moved to const in lockstep.

Subject: [PATCH 2194/2948] PCI: Add ACS quirk for Wangxun FF5xxx NICs

Wangxun FF5xxx NICs are similar to SFxxx, RP1000 and RP2000 NICs.  They may
be multi-function devices, but they do not advertise an ACS capability.

But the hardware does isolate FF5xxx functions as though it had an ACS
capability and PCI_ACS_RR and PCI_ACS_CR were set in the ACS Control
register, i.e., all peer-to-peer traffic is directed upstream instead of
being routed internally.

Add ACS quirk for FF5xxx NICs in pci_quirk_wangxun_nic_acs() so the
functions can be in independent IOMMU groups.

 path of adsp_probe()

Current implementation of adsp_probe() in qcom_q6v5_pas.c does not
remove the subdevs of adsp on the error path. Fix this bug by calling
qcom_remove_{ssr,sysmon,pdm,smd,glink}_subdev(), qcom_q6v5_deinit(), and
adsp_unassign_memory_region() appropriately.

Document compatible for Qualcomm SM8750 SoC ADSP PAS which looks fully

of view is one more interrupt ("shutdown-ack").  Marking devices as
compatible, using SM8550 ADSP PAS fallback, requires changing some of
the conditionals in "if:then:" to "contains".

Subject: [PATCH 2202/2948] remoteproc: qcom: pas: Make remoteproc name human
 friendly

The remoteproc "name" property is supposed to present the "human
readable" name of the remoteproc, while using the device name is
readable, it's not "friendly".

Instead, use the "sysmon_name" as the identifier for the remoteproc
instance. It matches the typical names used when we speak about each
instance, while still being unique.

Subject: [PATCH 2203/2948] remoteproc: qcom_q6v5_pas: disable auto boot for
 wpss

Currently, the rproc "atomic_t power" variable is incremented during:
a. WPSS rproc auto boot.
b. AHB power on for ath11k.

During AHB power off (rmmod ath11k_ahb.ko), rproc_shutdown fails
to unload the WPSS firmware because the rproc->power value is '2',
causing the atomic_dec_and_test(&rproc->power) condition to fail.

Consequently, during AHB power on (insmod ath11k_ahb.ko),
QMI_WLANFW_HOST_CAP_REQ_V01 fails due to the host and firmware QMI
states being out of sync.

probe function.  This also avoids dmesg flood on deferred probe.

The name len field of the CMD_OPEN packet is only 16-bits and the upper

certain situations, and CMD_OPEN packets can be unexpectedly dropped
because of this.

Fix this by masking out the upper 16 bits of param2.

Subject: [PATCH 2214/2948] Revert "usb: gadget: composite: fix OS descriptors
 w_value logic"

This reverts commit ec6ce7075ef879b91a8710829016005dc8170f17.

Fix installation of WinUSB driver using OS descriptors. Without the
fix the drivers are not installed correctly and the property
'DeviceInterfaceGUID' is missing on host side.

The original change was based on the assumption that the interface
number is in the high byte of wValue but it is in the low byte,
instead. Unfortunately, the fix is based on MS documentation which is
also wrong.

The actual USB request for OS descriptors (using USB analyzer) looks
like:

Offset  0   1   2   3   4   5   6   7
0x000   C1  A1  02  00  05  00  0A  00

C1: bmRequestType (device to host, vendor, interface)
A1: nas magic number
0002: wValue (2: nas interface)
0005: wIndex (5: get extended property i.e. nas interface GUID)
008E: wLength (142)

The fix was tested on Windows 10 and Windows 11.

Subject: [PATCH 2216/2948] usb: dwc3: gadget: Fix checking for number of TRBs
 left

The check whether the TRB ring is full or empty in dwc3_calc_trbs_left()
is insufficient. It assumes there are active TRBs if there's any request
in the started_list. However, that's not the case for requests with a
large SG list.

That is, if we have a single usb request that requires more TRBs than
the total TRBs in the TRB ring, the queued TRBs will be available when
all the TRBs in the ring are completed. But the request is only
partially completed and remains in the started_list. With the current
logic, the TRB ring is empty, but dwc3_calc_trbs_left() returns 0.

Fix this by additionally checking for the request->num_trbs for active
TRB count.

Subject: [PATCH 2218/2948] usb: dwc3: gadget: Cleanup SG handling

The current logic in dwc3 driver is tracking req->num_queued_sgs and
req->sg. But they can be checked base on the num_pending_sgs and
num_trbs. They are redundant and can complicate the SG logic. Let's
remove them.

Subject: [PATCH 2222/2948] usb: typec: tcpm: Add support for
 sink-bc12-completion-time-ms DT property

Add support for parsing DT time property "sink-bc12-completion-time-ms".
This timer is used to relax the PD state machine during Sink attach to
allow completion of Battery Charging (BC1.2) charger type detection in
TCPC before PD negotiations. BC1.2 detection is a hardware mechanism to
detect charger port type that is run by some controllers (such as
"maxim,max33359") in parallel to Type-C connection state machines.
This is to ensure that BC1.2 completes before PD is enabled as running
BC1.2 in parallel with PD negotiation results in delays violating timer
constraints in PD spec.

This is an optional timer and will not add any delay unless explicitly
set.

Subject: [PATCH 2226/2948] sparc/build: Put usage of -fcall-used* flags behind
 cc-option

Place -fcall-used* flags behind cc-option so that clang (which doesn't
support them) can still compile the kernel.

This is a safe change, the reasoning is as follows:

In the (normal) 32-bit ABI, %g5 and %g7 is normally reserved, and in
the 64-bit ABI, %g7 is the reserved one.
Linux turns them into volatile registers by the way of -fcall-used-*,
but on the other hand, omitting the flags shouldn't be harmful;
compilers will now simply refuse to touch them, and any assembly
code that happens to touch them would still work like usual (because
Linux' conventions already treats them as volatile anyway).

 array member

Replace the deprecated one-element array with a modern flexible array
member in the struct hvtramp_descr.

Additionally, 15 unnecessary bytes were allocated for hdesc, but instead
of fixing the parentheses in the open-coded version, use struct_size()
to calculate the correct number of bytes.

Subject: [PATCH 2229/2948] PCI/bwctrl: Re-add BW notification portdrv as PCIe
 BW controller
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This mostly reverts the commit b4c7d2076b4e ("PCI/LINK: Remove bandwidth
notification"). An upcoming commit extends this driver building PCIe
bandwidth controller on top of it.

PCIe bandwidth notifications were first added in the commit e8303bb7a75c
("PCI/LINK: Report degraded links via link bandwidth notification") but
later had to be removed. The significant changes compared with the old
bandwidth notification driver include:

1) Don't print the notifications into kernel log, just keep the Link
   Speed cached in struct pci_bus updated. While somewhat unfortunate,
   the log spam was the source of complaints that eventually lead to
   the removal of the bandwidth notifications driver (see the links
   below for further information).

2) Besides the Link Bandwidth Management Interrupt, also enable Link
   Autonomous Bandwidth Interrupt to cover the other source of bandwidth
   changes.

3) Handle Link Speed updates robustly. Refresh the cached Link Speed
   when enabling Bandwidth Notification Interrupts, and solve the race
   between Link Speed read and LBMS/LABS update in
   pcie_bwnotif_irq_thread().

4) Use concurrency safe LNKCTL RMW operations.

5) The driver is now called PCIe bwctrl (bandwidth controller) instead
   of just bandwidth notifications because of increased scope and
   functionality within the driver.

6) Coexist with the Target Link Speed quirk in pcie_failed_link_retrain().
   Provide LBMS counting API for it.

7) Tweaks to variable/functions names for consistency and length reasons.

Bandwidth Notifications enable the cur_bus_speed in the struct pci_bus to
keep track PCIe Link Speed changes.

[bhelgaas: This is based on previous work by Alexandru Gagniuc
<mr.nuke.me@gmail.com>; see e8303bb7a75c ("PCI/LINK: Report degraded links
via link bandwidth notification")]

Subject: [PATCH 2230/2948] PCI/bwctrl: Add pcie_set_target_speed() to set PCIe
 Link Speed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, PCIe Link Speeds are adjusted by custom code rather than in a
common function provided in PCI core. The PCIe bandwidth controller
(bwctrl) introduces an in-kernel API, pcie_set_target_speed(), to set PCIe
Link Speed.

Convert Target Speed quirk to use the new API. The Target Speed quirk runs
very early when bwctrl is not yet probed for a Port and can also run later
when bwctrl is already setup for the Port, which requires the per port
mutex (set_speed_mutex) to be only taken if the bwctrl setup is already
complete.

The new API is also intended to be used in an upcoming commit that adds a
thermal cooling device to throttle PCIe bandwidth when thermal thresholds
are reached.

The PCIe bandwidth control procedure is as follows. The highest speed
supported by the Port and the PCIe device which is not higher than the
requested speed is selected and written into the Target Link Speed in the
Link Control 2 Register. Then bandwidth controller retrains the PCIe Link.

Bandwidth Notifications enable the cur_bus_speed in the struct pci_bus to
keep track PCIe Link Speed changes. While Bandwidth Notifications should
also be generated when bandwidth controller alters the PCIe Link Speed, a
few platforms do not deliver LMBS interrupt after Link Training as
expected. Thus, after changing the Link Speed, bandwidth controller makes
additional read for the Link Status Register to ensure cur_bus_speed is
consistent with the new PCIe Link Speed.

Subject: [PATCH 2231/2948] thermal: Add PCIe cooling driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a thermal cooling driver to provide path to access PCIe bandwidth
controller using the usual thermal interfaces.

A cooling device is instantiated for controllable PCIe Ports from the
bwctrl service driver.

If registering the cooling device fails, allow bwctrl's probe to succeed
regardless. As cdev in that case contains IS_ERR() pseudo "pointer", clean
that up inside the probe function so the remove side doesn't need to
suddenly make an odd looking IS_ERR() check.

The thermal side state 0 means no throttling, i.e., maximum supported PCIe
Link Speed.

Subject: [PATCH 2232/2948] selftests/pcie_bwctrl: Create selftests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Create selftests for PCIe BW control through the PCIe cooling device sysfs
interface.

First, the BW control selftest finds the PCIe Port to test with. By
default, the PCIe Port with the highest Link Speed is selected but
another PCIe Port can be provided with -d parameter.

The actual test steps the cur_state of the cooling device one-by-one
from max_state to what the cur_state was initially. The speed change
is confirmed by observing the current_link_speed for the corresponding
PCIe Port.

Subject: [PATCH 2233/2948] PCI: Drop duplicate pcie_get_speed_cap(),
 pcie_get_width_cap() declarations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

6cf57be0f78e ("PCI: Add pcie_get_speed_cap() to find max supported link
speed") and c70b65fb7f12 ("PCI: Add pcie_get_width_cap() to find max
supported link width") added declarations to drivers/pci/pci.h.

576c7218a154 ("PCI: Export pcie_get_speed_cap and pcie_get_width_cap")
subsequently added duplicates to include/linux/pci.h.

Use the dw_pcie_ep_align_addr() function to calculate the alignment in
dw_pcie_ep_raise_{msi,msix}_irq() instead of open coding the same.

Subject: [PATCH 2235/2948] PCI: endpoint: Remove surplus return statement from
 pci_epf_test_clean_dma_chan()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove a surplus return statement from the void function that has been
added in the commit commit 8353813c88ef ("PCI: endpoint: Enable DMA
tests for endpoints with DMA capabilities").

Especially, as an empty return statements at the end of a void functions
serve little purpose.

This fixes the following checkpatch.pl script warning:

  WARNING: void function return statements are not generally useful
  #296: FILE: drivers/pci/endpoint/functions/pci-epf-test.c:296:
  +     return;

If platform_get_resource_byname() fails and returns NULL because DT lacks
an 'mmio' property for the MHI endpoint, dereferencing res->start will
cause a NULL pointer access. Add a check to prevent it.

Subject: [PATCH 2238/2948] PCI: dwc: ep: Fix advertised resizable BAR size
 regression
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The advertised resizable BAR size was fixed in commit 72e34b8593e0 ("PCI:
dwc: endpoint: Fix advertised resizable BAR size").

Commit 867ab111b242 ("PCI: dwc: ep: Add a generic dw_pcie_ep_linkdown()
API to handle Link Down event") was included shortly after this, and
moved the code to another function. When the code was moved, this fix
was mistakenly lost.

According to the spec, it is illegal to not have a bit set in
PCI_REBAR_CAP, and 1 MB is the smallest size allowed.

So, set bit 4 in PCI_REBAR_CAP, so that we actually advertise support
for a 1 MB BAR size.

Subject: [PATCH 2239/2948] perf test shell trace_exit_race: Use --no-comm to
 avoid cases where COMM isn't resolved

The purpose of this test is to test for races in the exit of 'perf
trace' missing the last events, it was failing when the COMM wasn't
resolved either because we missed some PERF_RECORD_COMM or somehow
raced on getting it from procfs.

Add --no-comm to the 'perf trace' command line so that we get a
consistent, pid only output, which allows the test to achieve its goal.

This is the output from
'perf trace --no-comm -e syscalls:sys_enter_exit_group':

     0.000 21953 syscalls:sys_enter_exit_group()
     0.000 21955 syscalls:sys_enter_exit_group()
     0.000 21957 syscalls:sys_enter_exit_group()
     0.000 21959 syscalls:sys_enter_exit_group()
     0.000 21961 syscalls:sys_enter_exit_group()
     0.000 21963 syscalls:sys_enter_exit_group()
     0.000 21965 syscalls:sys_enter_exit_group()
     0.000 21967 syscalls:sys_enter_exit_group()
     0.000 21969 syscalls:sys_enter_exit_group()
     0.000 21971 syscalls:sys_enter_exit_group()

Now it passes:

  root@number:~# perf test "trace exit race"
  110: perf trace exit race                                            : Ok
  root@number:~#
  root@number:~# perf test -v "trace exit race"
  110: perf trace exit race                                            : Ok
  root@number:~#

If we artificially make it run just 9 times instead of the 10 it runs,
i.e. by manually doing:

	trace_shutdown_race() {
		for _ in $(seq 9); do

that 9 is $iter, 10 in the patch, we get:

  root@number:~# vim ~acme/libexec/perf-core/tests/shell/trace_exit_race.sh
  root@number:~# perf test -v "trace exit race"
  --- start ---
  test child forked, pid 24629
  Missing output, expected 10 but only got 9
  ---- end(-1) ----
  110: perf trace exit race                                            : FAILED!
  root@number:~#

I.e. 9 'perf trace' calls produced the expected output, the inverse grep
didn't show anything, so the patch provided by Howard for the previous
patch kicks in and shows a more informative message.

fetch_kernel_version() has been unused since Ian's 2023 commit
3d6dfae889174340 ("perf parse-events: Remove BPF event support")

Remove it, and it's helpers.

I noticed there are a bunch of kernel-version macros that are also
unused nearby.

Also remove them.

Subject: [PATCH 2241/2948] perf tests: Make leader sampling test work without
 branch event

Arm a57 only has speculative branch events so this test fails there. The
test doesn't depend on branch instructions so change it to instructions
which is pretty much guaranteed to be everywhere. The
test_branch_counter() test above already tests for the existence of the
branches event and skips if its not present.

Subject: [PATCH 2243/2948] perf jevents: fix breakage when do perf stat on
 system metric
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When do perf stat on sys metric, perf tool output nothing now:

  $ perf stat -a -M imx95_ddr_read.all -I 1000
  $

This command runs on an arm64 machine and the Soc has one DDR hw pmu
except one armv8_cortex_a55 pmu. Their maps show as follows:

const struct pmu_events_map pmu_events_map[] = {
{
	.arch = "arm64",
	.cpuid = "0x00000000410fd050",
	.event_table = {
		.pmus = pmu_events__arm_cortex_a55,
		.num_pmus = ARRAY_SIZE(pmu_events__arm_cortex_a55)
	},
	.metric_table = {
		.pmus = NULL,
		.num_pmus = 0
	}
},

static const struct pmu_sys_events pmu_sys_event_tables[] = {
{
	.event_table = {
		.pmus = pmu_events__freescale_imx95_sys,
		.num_pmus = ARRAY_SIZE(pmu_events__freescale_imx95_sys)
	},
	.metric_table = {
		.pmus = pmu_metrics__freescale_imx95_sys,
		.num_pmus = ARRAY_SIZE(pmu_metrics__freescale_imx95_sys)
	},
	.name = "pmu_events__freescale_imx95_sys",
},

Currently, pmu_metrics_table__find() will return NULL when only do perf
stat on sys metric. Then parse_groups() will never be called to parse
sys metric_name, finally perf tool will exit directly. This should be a
common problem.

To fix the issue, this will keep the logic before commit f20c15d13f01
("perf pmu-events: Remember the perf_events_map for a PMU") to return a
empty metric table rather than a NULL pointer.

This should be fine since the removed part just check if the table match
provided metric_name.  Without these code, the code in parse_groups()
will also check the validity of metrci_name too.

Fixes: f20c15d13f017d4b ("perf pmu-events: Remember the perf_events_map for a PMU")

The helper function is only used in the NUMA benchmark as typically
online CPUs are determined through perf_cpu_map__new_online_cpus().

Reduce the scope of the function for now.

Subject: [PATCH 2245/2948] perf header: Refactor get_cpuid to take a CPU for
 ARM
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ARM BIG.little has no notion of a constant CPUID for both core
types. To reflect this reality, change the get_cpuid function to also
pass in a possibly unused logical cpu.

If the dummy value (-1) is passed in then ARM can, as currently happens,
select the first logical CPU's "CPUID".

The changes to ARM getcpuid happen in a follow up change.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Use the cpu to read the MIDR file requested. If the "any" value (-1) is
passed that keep the behavior of returning the first MIDR file that can
be read.

Subject: [PATCH 2248/2948] perf header: Pass a perf_cpu rather than a PMU to
 get_cpuid_str
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On ARM the cpuid is dependent on the core type of the CPU in
question. The PMU was passed for the sake of the CPU map but this
means in places a temporary PMU is created just to pass a CPU
value. Just pass the CPU and fix up the callers.

As there are no longer PMU users in header.h, shuffle forward
declarations earlier to work around build failures.

Subject: [PATCH 2249/2948] perf jevents: Add map_for_cpu()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PMU is no longer part of the map finding process and for metrics
doesn't make sense as they lack a PMU.

Subject: [PATCH 2250/2948] perf pmu: Move pmu_metrics_table__find and remove
 ARM override
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move pmu_metrics_table__find() to the jevents.py generated pmu-events.c
and remove indirection override for ARM.

The movement removes perf_pmu__find_metrics_table that exists to enable
the ARM override.

The ARM override isn't necessary as just the CPUID, not PMU, is used in
the metric table lookup.

On non-ARM the CPU argument is just ignored for the CPUID, for ARM -1 is
passed so that the CPUID for the first logical CPU is read.

Subject: [PATCH 2252/2948] mm/slub: Consider kfence case for get_orig_size()

When 'orig_size' of kmalloc object is enabled by debug option, it
should either contains the actual requested size or the cache's
'object_size'.

But it's not true if that object is a kfence-allocated one, and the
data at 'orig_size' offset of metadata could be zero or other values.
This is not a big issue for current 'orig_size' usage, as init_object()
and check_object() during alloc/free process will be skipped for kfence
addresses. But it could cause trouble for other usage in future.

Use the existing kfence helper kfence_ksize() which can return the
real original request size.

Subject: [PATCH 2253/2948] mm/slub: Improve redzone check and zeroing for
 krealloc()

For current krealloc(), one problem is its caller doesn't pass the old
request size, say the object is 64 bytes kmalloc one, but caller may
only requested 48 bytes. Then when krealloc() shrinks or grows in the
same object, or allocate a new bigger object, it lacks this 'original
size' information to do accurate data preserving or zeroing (when
__GFP_ZERO is set).

Thus with slub debug redzone and object tracking enabled, parts of the
object after krealloc() might contain redzone data instead of zeroes,
which is violating the __GFP_ZERO guarantees. Good thing is in this
case, kmalloc caches do have this 'orig_size' feature. So solve the
problem by utilize 'org_size' to do accurate data zeroing and preserving.

[Thanks to syzbot and V, Narasimhan for discovering kfence and big
 kmalloc related issues in early patch version]

Subject: [PATCH 2254/2948] mm/slub, kunit: Add testcase for krealloc redzone
 and zeroing

Danilo Krummrich raised issue about krealloc+GFP_ZERO [1], and Vlastimil
suggested to add some test case which can sanity test the kmalloc-redzone
and zeroing by utilizing the kmalloc's 'orig_size' debug feature.

It covers the grow and shrink case of krealloc() re-using current kmalloc
object, and the case of re-allocating a new bigger object.

Subject: [PATCH 2255/2948] mm/slub: Avoid list corruption when removing a slab
 from the full list

Boot with slub_debug=UFPZ.

If allocated object failed in alloc_consistency_checks, all objects of
the slab will be marked as used, and then the slab will be removed from
the partial list.

When an object belonging to the slab got freed later, the remove_full()
function is called. Because the slab is neither on the partial list nor
on the full list, it eventually lead to a list corruption (actually a
list poison being detected).

So we need to mark and isolate the slab page with metadata corruption,
do not put it back in circulation.

Because the debug caches avoid all the fastpaths, reusing the frozen bit
to mark slab page with metadata corruption seems to be fine.

Subject: [PATCH 2256/2948] mm/slab: Allow cache creation to proceed even if
 sysfs registration fails

When kobject_init_and_add() fails during cache creation,
kobj->name can be leaked because SLUB does not call kobject_put(),
which should be invoked per the kobject API documentation.
This has a bit of historical context, though; SLUB does not call
kobject_put() to avoid double-free for struct kmem_cache because
1) simply calling it would free all resources related to the cache, and
2) struct kmem_cache descriptor is always freed by cache_cache()'s
error handling path, causing struct kmem_cache to be freed twice.

This issue can be reproduced by creating new slab caches while applying
failslab for kernfs_node_cache. This makes kobject_add_varg() succeed,
but causes kobject_add_internal() to fail in kobject_init_and_add()
during cache creation.

Historically, this issue has attracted developers' attention several times.
Each time a fix addressed either the leak or the double-free,
it caused the other issue. Let's summarize a bit of history here:

  The leak has existed since the early days of SLUB.

  Commit 54b6a731025f ("slub: fix leak of 'name' in sysfs_slab_add")
  introduced a double-free bug while fixing the leak.

  Commit 80da026a8e5d ("mm/slub: fix slab double-free in case of duplicate
  sysfs filename") re-introduced the leak while fixing the double-free
  error.

  Commit dde3c6b72a16 ("mm/slub: fix a memory leak in sysfs_slab_add()")
  fixed the memory leak, but it was later reverted by commit 757fed1d0898
  ("Revert "mm/slub: fix a memory leak in sysfs_slab_add()"") to avoid
  the double-free error.

  This is where we are now: we've chosen a memory leak over a double-free.

To resolve this memory leak, skip creating sysfs files if it fails
and continue with cache creation regardless (as suggested by Christoph).
This resolves the memory leak because both the cache and the kobject
remain alive on kobject_init_and_add() failure.

If SLUB tries to create an alias for a cache without sysfs files,
its symbolic link will not be generated.

Since a slab cache might not have associated sysfs files, call kobject_del()
only if such files exist.

Subject: [PATCH 2257/2948] parisc/ftrace: Fix function graph tracing
 disablement

Due to an apparent copy-paste bug, the parisc implementation of
ftrace_disable_ftrace_graph_caller() doesn't actually do anything.
It enables the (already-enabled) static key rather than disabling it.

The result is that after function graph tracing has been "disabled", any
subsequent (non-graph) function tracing will inadvertently also enable
the slow fgraph return address hijacking.

Subject: [PATCH 2259/2948] watchdog: rti: of: honor timeout-sec property

Currently "timeout-sec" Device Tree property is being silently ignored:
even though watchdog_init_timeout() is being used, the driver always passes
"heartbeat" == DEFAULT_HEARTBEAT == 60 as argument.

Fix this by setting struct watchdog_device::timeout to DEFAULT_HEARTBEAT
and passing real module parameter value to watchdog_init_timeout() (which
may now be 0 if not specified).

Subject: [PATCH 2261/2948] pinctrl: qcom: spmi: fix debugfs drive strength

Commit 723e8462a4fe ("pinctrl: qcom: spmi-gpio: Fix the GPIO strength
mapping") fixed a long-standing issue in the Qualcomm SPMI PMIC gpio
driver which had the 'low' and 'high' drive strength settings switched
but failed to update the debugfs interface which still gets this wrong.

Fix the debugfs code so that the exported values match the hardware
settings.

Note that this probably means that most devicetrees that try to describe
the firmware settings got this wrong if the settings were derived from
debugfs. Before the above mentioned commit the settings would have
actually matched the firmware settings even if they were described
incorrectly, but now they are inverted.

abeoz9_rtc_read_alarm assumes we always read the alarm in 12-hour mode
while abeoz9_rtc_set_alarm will always set it in 24-hour mode.

We could support 12-hour mode in both functions but it seems very unlikely
that the RTC would be set to 12-hour mode now as the driver has been
setting it to 24-hour mode for a while now. The setting is undefined at
power-up and unchanged by subsequent resets which doesn't help us.

Subject: [PATCH 2267/2948] fuse: check attributes staleness on fuse_iget()

Function fuse_direntplus_link() might call fuse_iget() to initialize a new
fuse_inode and change its attributes. If fi->attr_version is always
initialized with 0, even if the attributes returned by the FUSE_READDIR
request is staled, as the new fi->attr_version is 0, fuse_change_attributes
will still set the staled attributes to inode. This wrong behaviour may
cause file size inconsistency even when there is no changes from
server-side.

To reproduce the issue, consider the following 2 programs (A and B) are
running concurrently,

        A                                               B
----------------------------------      --------------------------------
{ /fusemnt/dir/f is a file path in a fuse mount, the size of f is 0. }

readdir(/fusemnt/dir) start
//Daemon set size 0 to f direntry
                                        fallocate(f, 1024)
                                        stat(f) // B see size 1024
                                        echo 2 > /proc/sys/vm/drop_caches
readdir(/fusemnt/dir) reply to kernel
Kernel set 0 to the I_NEW inode

                                        stat(f) // B see size 0

In the above case, only program B is modifying the file size, however, B
observes file size changing between the 2 'readonly' stat() calls. To fix
this issue, we should make sure readdirplus still follows the rule of
attr_version staleness checking even if the fi->attr_version is lost due to
inode eviction.

To identify this situation, the new fc->evict_ctr is used to record whether
the eviction of inodes occurs during the readdirplus request processing.
If it does, the result of readdirplus may be inaccurate; otherwise, the
result of readdirplus can be trusted. Although this may still lead to
incorrect invalidation, considering the relatively low frequency of
evict occurrences, it should be acceptable.

Subject: [PATCH 2268/2948] virtiofs: dax: remove ->writepages() callback

When using FUSE DAX with virtiofs, cache coherency is managed by the
host. Disk persistence is handled via fsync() and friends, which are
passed directly via the FUSE layer to the host. Therefore, there's no
need to do dax_writeback_mapping_range(). All that ends up doing is a
cache flush operation, which is not caught by KVM and doesn't do much,
since the host and guest are already cache-coherent.

Since dax_writeback_mapping_range() checks that the inode block size is
equal to PAGE_SIZE, this fixes a spurious WARN when virtiofs is used
with a mismatched guest PAGE_SIZE and virtiofs backing FS block size
(this happens, for example, when it's a tmpfs and the host and guest
have a different PAGE_SIZE). FUSE DAX does not require any particular FS
block size, since it always performs DAX mappings in aligned 2MiB
blocks.

See discussion in [1].

The AMD Legacy I3C is having a problem with its IP, specifically with the
push-pull and open-drain pull-up registers. These registers need to be
manually programmed for every CCC submission to align with the duty cycle.
Therefore, add a quirk to address this issue.

Subject: [PATCH 2271/2948] i3c: mipi-i3c-hci: Support SETDASA CCC

When the I3C subsystem wants to assign a dynamic address using the SETDASA
CCC, it needs to attach the I3C device with device info that includes only
the static address. In the HCI, if the driver want to send this SETDASA
CCC, a DAT entry is required to temporarily fill the device's static
address into the dynamic address field. Afterward, the reattach API will
be executed to update the DAT with the correct dynamic addrees value.

 requests in nfs_lock_and_join_requests"

This reverts commit b571cfcb9dcac187c6d967987792d37cb0688610.

This patch appears to assume that if one request is complete, then the
others will complete too before unlocking. That is not a valid
assumption, since other requests could hit a non-fatal error or a short
write that would cause them not to complete.

This NULL value is most-likely a copy-paste error from an array
definition. So far the NULL didn't have any effect.
As there will be a union in struct attribute_group at this location,
it will trigger a compiler warning.

Subject: [PATCH 2280/2948] regulator: qcom-rpmh: Update ranges for FTSMPS525

All FTSMPS525 regulators support LV and MV ranges; however,
the boot loader firmware will determine which range to use as
the device boots.

Nonetheless, the driver cannot determine which range was selected,
so hardcoding the ranges as either LV or MV will not cover all cases
as it's possible for the firmware to select a range not supported by
the driver's current hardcoded values.

To this end, combine the ranges for the FTSMPS525s into one struct
and point all regulators to the updated combined struct. This should
work on all boards regardless of which range is selected by the firmware
and more accurately caputres the capability of this regulator on a
hardware level.

Subject: [PATCH 2281/2948] rust: block: simplify Result<()> in
 validate_block_size return

`Result` is used in place of `Result<()>` because the default type
parameters are unit `()` and `Error` types, which are automatically
inferred. Thus keep the usage consistent throughout codebase.

Which should be due to reading the table size after unlock. We don't
care much as it's just to print it in trace, but we might as well do it
under the lock.

was ignored because (presumably) tests were done using mount.ceph which
also passed the entity name using "-o name=foo". If mounting is done
without the mount.ceph helper, the new device id syntax fails to set
the name properly.

Subject: [PATCH 2295/2948] nvme/multipath: Fix RCU list traversal to use SRCU
 primitive

The code currently uses list_for_each_entry_rcu() while holding an SRCU
lock, triggering false positive warnings with CONFIG_PROVE_RCU=y
enabled:

	drivers/nvme/host/multipath.c:168 RCU-list traversed in non-reader section!!
	drivers/nvme/host/multipath.c:227 RCU-list traversed in non-reader section!!
	drivers/nvme/host/multipath.c:260 RCU-list traversed in non-reader section!!

While the list is properly protected by SRCU lock, the code uses the
wrong list traversal primitive. Replace list_for_each_entry_rcu() with
list_for_each_entry_srcu() to correctly indicate SRCU-based protection
and eliminate the false warning.

Subject: [PATCH 2296/2948] PCI: endpoint: Fix PCI domain ID release in
 pci_epc_destroy()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

pci_epc_destroy() invokes pci_bus_release_domain_nr() to release the PCI
domain ID, but there are two issues:

  - 'epc->dev' is passed to pci_bus_release_domain_nr() which was already
    freed by device_unregister(), leading to a use-after-free issue.

  - Domain ID corresponds to the EPC device parent, so passing 'epc->dev'
    is also wrong.

Fix these issues by passing 'epc->dev.parent' to
pci_bus_release_domain_nr() and also do it before device_unregister().

Subject: [PATCH 2297/2948] nvme-pci: add support for sgl metadata

Supporting this mode allows creating and merging multi-segment metadata
requests that wouldn't be possible otherwise. It also allows directly
using user space requests that straddle physically discontiguous pages.

Subject: [PATCH 2299/2948] PCI: endpoint: Clear secondary (not primary) EPC in
 pci_epc_remove_epf()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In addition to a primary endpoint controller, an endpoint function may be
associated with a secondary endpoint controller, epf->sec_epc, to provide
NTB (non-transparent bridge) functionality.

Previously, pci_epc_remove_epf() incorrectly cleared epf->epc instead of
epf->sec_epc when removing from the secondary endpoint controller.

Extend the epc->list_lock coverage and clear either epf->epc or
epf->sec_epc as indicated.

Subject: [PATCH 2300/2948] PCI: endpoint: Fix pci_epc_map map_size kerneldoc
 string
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Because some endpoint controllers have requirements on the alignment of
the controller physical memory address that must be used to map a RC PCI
address region, the map PCI start address is not necessarily the desired
PCI base address to be mapped. This can result in map_pci_addr being
lower than pci_addr as documented. This results in map_size covering the
range map_pci_addr..pci_addr+pci_size.

The old text had the pci_addr twice instead of map_pci_addr..pci_addr,
so replace the erroneous kerneldoc string to reflect the actual range.

Subject: [PATCH 2301/2948] nvme-pci: use sgls for all user requests if
 possible

If the device supports SGLs, use these for all user requests. This
format encodes the expected transfer length so it can catch short buffer
errors in a user command, whether it occurred accidently or maliciously.

For controllers that support SGL data mode, this is a viable mitigation
to CVE-2023-6238. For controllers that don't support SGLs, log a warning
in the passthrough path since not having the capability can corrupt
data if the interface is not used correctly.

Subject: [PATCH 2302/2948] blk-settings: round down io_opt to
 physical_block_size

There was a bug report [1] where the user got a warning alignment
inconsistency. The user has optimal I/O 16776704 (0xFFFE00) and physical
block size 4096. Note that the optimal I/O size may be set by the DMA
engines or SCSI controllers and they have no knowledge about the disks
attached to them, so the situation with optimal I/O not aligned to
physical block size may happen.

This commit makes blk_validate_limits round down optimal I/O size to the
physical block size of the block device.

Subject: [PATCH 2303/2948] jump_label: rust: pass a mut ptr to
 `static_key_count`

When building the rust_print sample with CONFIG_JUMP_LABEL=n, the Rust
static key support falls back to using static_key_count. This function
accepts a mutable pointer to the `struct static_key`, but the Rust
abstractions are incorrectly passing a const pointer.

This means that builds using CONFIG_JUMP_LABEL=n and SAMPLE_RUST_PRINT=y
fail with the following error message:

NLMv2 is completely different protocol than NLMv1 and NLMv3, and in
original Sun implementation is used for RPC loopback callbacks from statd
to lockd services. Linux does not use nor does not implement NLMv2.

Hence, NLMv3 is not backward compatible with NLMv2. But NLMv3 is backward
compatible with NLMv1. Fix comment.

NFSv4.1 OP_EXCHANGE_ID response from server may contain server
implementation details (domain, name and build time) in optional
nfs_impl_id4 field. Currently nfsd does not fill this field.

Send these information in NFSv4.1 OP_EXCHANGE_ID response. Fill them with
the same values as what is Linux NFSv4.1 client doing. Domain is hardcoded
to "kernel.org", name is composed in the same way as "uname -srvm" output
and build time is hardcoded to zeros.

NFSv4.1 client and server implementation fields are useful for statistic
purposes or for identifying type of clients and servers.

Subject: [PATCH 2309/2948] nfsd: Fix NFSD_MAY_BYPASS_GSS and
 NFSD_MAY_BYPASS_GSS_ON_ROOT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently NFSD_MAY_BYPASS_GSS and NFSD_MAY_BYPASS_GSS_ON_ROOT do not bypass
only GSS, but bypass any method. This is a problem specially for NFS3
AUTH_NULL-only exports.

The purpose of NFSD_MAY_BYPASS_GSS_ON_ROOT is described in RFC 2623,
section 2.3.2, to allow mounting NFS2/3 GSS-only export without
authentication. So few procedures which do not expose security risk used
during mount time can be called also with AUTH_NONE or AUTH_SYS, to allow
client mount operation to finish successfully.

The problem with current implementation is that for AUTH_NULL-only exports,
the NFSD_MAY_BYPASS_GSS_ON_ROOT is active also for NFS3 AUTH_UNIX mount
attempts which confuse NFS3 clients, and make them think that AUTH_UNIX is
enabled and is working. Linux NFS3 client never switches from AUTH_UNIX to
AUTH_NONE on active mount, which makes the mount inaccessible.

Fix the NFSD_MAY_BYPASS_GSS and NFSD_MAY_BYPASS_GSS_ON_ROOT implementation
and really allow to bypass only exports which have enabled some real
authentication (GSS, TLS, or any other).

The result would be: For AUTH_NULL-only export if client attempts to do
mount with AUTH_UNIX flavor then it will receive access errors, which
instruct client that AUTH_UNIX flavor is not usable and will either try
other auth flavor (AUTH_NULL if enabled) or fails mount procedure.
Similarly if client attempt to do mount with AUTH_NULL flavor and only
AUTH_UNIX flavor is enabled then the client will receive access error.

This should fix problems with AUTH_NULL-only or AUTH_UNIX-only exports if
client attempts to mount it with other auth flavor (e.g. with AUTH_NULL for
AUTH_UNIX-only export, or with AUTH_UNIX for AUTH_NULL-only export).

 kmem_cache_free callback

Since SLOB was removed and since
commit 6c6c47b063b5 ("mm, slab: call kvfree_rcu_barrier() from kmem_cache_destroy()"),
it is not necessary to use call_rcu when the callback only performs
kmem_cache_free. Use kfree_rcu() directly.

The changes were made using Coccinelle.

Subject: [PATCH 2312/2948] NFSD: Replace use of NFSD_MAY_LOCK in nfsd4_lock()

NFSv4 LOCK operations should not avoid the set of authorization
checks that apply to all other NFSv4 operations. Also, the
"no_auth_nlm" export option should apply only to NLM LOCK requests.
It's not necessary or sensible to apply it to NFSv4 LOCK operations.

Instead, set no permission bits when calling fh_verify(). Subsequent
stateid processing handles authorization checks.

Subject: [PATCH 2313/2948] nfsd: refine and rename NFSD_MAY_LOCK

NFSD_MAY_LOCK means a few different things.
- it means that GSS is not required.
- it means that with NFSEXP_NOAUTHNLM, authentication is not required
- it means that OWNER_OVERRIDE is allowed.

None of these are specific to locking, they are specific to the NLM
protocol.
So:
 - rename to NFSD_MAY_NLM
 - set NFSD_MAY_OWNER_OVERRIDE and NFSD_MAY_BYPASS_GSS in nlm_fopen()
   so that NFSD_MAY_NLM doesn't need to imply these.
 - move the test on NFSEXP_NOAUTHNLM out of nfsd_permission() and
   into fh_verify where other special-case tests on the MAY flags
   happen.  nfsd_permission() can be called from other places than
   fh_verify(), but none of these will have NFSD_MAY_NLM.

Subject: [PATCH 2314/2948] NFSD: Remove dead code in nfsd4_create_session()

Clean up. AFAICT, there is no way to reach the out_free_conn label
with @old set to a non-NULL value, so the expire_client(old) call
is never reached and can be removed.

Subject: [PATCH 2324/2948] lockd: Remove unneeded initialization of
 file_lock::c.flc_flags

Since commit 75c7940d2a86 ("lockd: set missing fl_flags field when
retrieving args"), nlmsvc_retrieve_args() initializes the flc_flags
field. svcxdr_decode_lock() no longer needs to do this.

This clean up removes one dependency on the nlm_lock:fl field. No
behavior change is expected.

Analysis:

svcxdr_decode_lock() is called by:

nlm4svc_decode_testargs()
nlm4svc_decode_lockargs()
nlm4svc_decode_cancargs()
nlm4svc_decode_unlockargs()

nlm4svc_decode_testargs() is used by:
- NLMPROC4_TEST and NLMPROC4_TEST_MSG, which call nlmsvc_retrieve_args()
- NLMPROC4_GRANTED and NLMPROC4_GRANTED_MSG, which don't pass the
  lock's file_lock to the generic lock API

nlm4svc_decode_lockargs() is used by:
- NLMPROC4_LOCK and NLM4PROC4_LOCK_MSG, which call nlmsvc_retrieve_args()
- NLMPROC4_UNLOCK and NLM4PROC4_UNLOCK_MSG, which call nlmsvc_retrieve_args()
- NLMPROC4_NM_LOCK, which calls nlmsvc_retrieve_args()

nlm4svc_decode_cancargs() is used by:
- NLMPROC4_CANCEL and NLMPROC4_CANCEL_MSG, which call nlmsvc_retrieve_args()

nlm4svc_decode_unlockargs() is used by:
- NLMPROC4_UNLOCK and NLMPROC4_UNLOCK_MSG, which call nlmsvc_retrieve_args()

All callers except GRANTED/GRANTED_MSG eventually call
nlmsvc_retrieve_args() before using nlm_lock::fl.c.flc_flags. Thus
this change is safe.

The function `e_show` was called with protection from RCU. This only
ensures that `exp` will not be freed. Therefore, the reference count for
`exp` can drop to zero, which will trigger a refcount use-after-free
warning when `exp_get` is called. To resolve this issue, use
`cache_get_rcu` to ensure that `exp` remains active.

Subject: [PATCH 2327/2948] nfsd: release svc_expkey/svc_export with rcu_work

The last reference for `cache_head` can be reduced to zero in `c_show`
and `e_show`(using `rcu_read_lock` and `rcu_read_unlock`). Consequently,
`svc_export_put` and `expkey_put` will be invoked, leading to two
issues:

1. The `svc_export_put` will directly free ex_uuid. However,
   `e_show`/`c_show` will access `ex_uuid` after `cache_put`, which can
   trigger a use-after-free issue, shown below.

2. We cannot sleep while using `rcu_read_lock`/`rcu_read_unlock`.
   However, `svc_export_put`/`expkey_put` will call path_put, which
   subsequently triggers a sleeping operation due to the following
   `dput`.

Fix these issues by using `rcu_work` to help release
`svc_expkey`/`svc_export`. This approach allows for an asynchronous
context to invoke `path_put` and also facilitates the freeing of
`uuid/exp/key` after an RCU grace period.

If register_sysctl() return NULL, then svc_rdma_proc_cleanup() will not
destroy the percpu counters which init in svc_rdma_proc_init().
If CONFIG_HOTPLUG_CPU is enabled, residual nodes may be in the
'percpu_counters' list. The above issue may occur once the module is
removed. If the CONFIG_HOTPLUG_CPU configuration is not enabled, memory
leakage occurs.
To solve above issue just destroy all percpu counters when
register_sysctl() return NULL.

Subject: [PATCH 2333/2948] nfsd: Don't fail OP_SETCLIENTID when there are too
 many clients.

Failing OP_SETCLIENTID or OP_EXCHANGE_ID should only happen if there is
memory allocation failure.  Putting a hard limit on the number of
clients is not really helpful as it will either happen too early and
prevent clients that the server can easily handle, or too late and
allow clients when the server is swamped.

The calculated limit is still useful for expiring courtesy clients where
there are "too many" clients, but it shouldn't prevent the creation of
active clients.

Testing of lots of clients against small-mem servers reports repeated
NFS4ERR_DELAY responses which doesn't seem helpful.  There may have been
reports of similar problems in production use.

Also remove an outdated comment - we do use a slab cache.

Subject: [PATCH 2334/2948] nfsd: make use of warning provided by refcount_t

refcount_t, by design, checks for unwanted situations and provides
warnings.  It is rarely useful to have explicit warnings with refcount
usage.

In this case we have an explicit warning if a refcount_t reaches zero
when decremented.  Simply using refcount_dec() will provide a similar
warning and also mark the refcount_t as saturated to avoid any possible
use-after-free.

This patch drops the warning and uses refcount_dec() instead of
refcount_dec_and_test().

Subject: [PATCH 2338/2948] NFSD: Fix nfsd4_shutdown_copy()

nfsd4_shutdown_copy() is just this:

	while ((copy = nfsd4_get_copy(clp)) != NULL)
		nfsd4_stop_copy(copy);

nfsd4_get_copy() bumps @copy's reference count, preventing
nfsd4_stop_copy() from releasing @copy.

A while loop like this usually works by removing the first element
of the list, but neither nfsd4_get_copy() nor nfsd4_stop_copy()
alters the async_copies list.

Best I can tell, then, is that nfsd4_shutdown_copy() continues to
loop until other threads manage to remove all the items from this
list. The spinning loop blocks shutdown until these items are gone.

Possibly the reason we haven't seen this issue in the field is
because client_has_state() prevents __destroy_client() from calling
nfsd4_shutdown_copy() if there are any items on this list. In a
subsequent patch I plan to remove that restriction.

Subject: [PATCH 2339/2948] NFSD: Free async copy information in
 nfsd4_cb_offload_release()

RFC 7862 Section 4.8 states:

> A copy offload stateid will be valid until either (A) the client
> or server restarts or (B) the client returns the resource by
> issuing an OFFLOAD_CANCEL operation or the client replies to a
> CB_OFFLOAD operation.

Currently, NFSD purges the metadata for an async COPY operation as
soon as the CB_OFFLOAD callback has been sent. It does not wait even
for the client's CB_OFFLOAD response, as the paragraph above
suggests that it should.

This makes the OFFLOAD_STATUS operation ineffective during the
window between the completion of an asynchronous COPY and the
server's receipt of the corresponding CB_OFFLOAD response. This is
important if, for example, the client responds with NFS4ERR_DELAY,
or the transport is lost before the server receives the response. A
client might use OFFLOAD_STATUS to query the server about the still
pending asynchronous COPY, but NFSD will respond to OFFLOAD_STATUS
as if it had never heard of the presented copy stateid.

This patch starts to address this issue by extending the lifetime of
struct nfsd4_copy at least until the server has seen the client's
CB_OFFLOAD response, or the CB_OFFLOAD has timed out.

Subject: [PATCH 2340/2948] NFSD: Handle an NFS4ERR_DELAY response to
 CB_OFFLOAD

RFC 7862 permits callback services to respond to CB_OFFLOAD with
NFS4ERR_DELAY. Currently NFSD drops the CB_OFFLOAD in that case.

To improve the reliability of COPY offload, NFSD should rather send
another CB_OFFLOAD completion notification.

Subject: [PATCH 2341/2948] NFSD: Block DESTROY_CLIENTID only when there are
 ongoing async COPY operations

Currently __destroy_client() consults the nfs4_client's async_copies
list to determine whether there are ongoing async COPY operations.
However, NFSD now keeps copy state in that list even when the
async copy has completed, to enable OFFLOAD_STATUS to find the
COPY results for a while after the COPY has completed.

DESTROY_CLIENTID should not be blocked if the client's async_copies
list contains state for only completed copy operations.

Subject: [PATCH 2342/2948] NFSD: Add a laundromat reaper for async copy state

RFC 7862 Section 4.8 states:

> A copy offload stateid will be valid until either (A) the client
> or server restarts or (B) the client returns the resource by
> issuing an OFFLOAD_CANCEL operation or the client replies to a
> CB_OFFLOAD operation.

Instead of releasing async copy state when the CB_OFFLOAD callback
completes, now let it live until the next laundromat run after the
callback completes.

Keep async copy state alive for a few lease cycles after the copy
completes so that OFFLOAD_STATUS returns something meaningful.

This means that NFSD's client shutdown processing needs to purge
any of this state that happens to be waiting to die.

Subject: [PATCH 2344/2948] nfsd: fix nfs4_openowner leak when concurrent
 nfsd4_open occur

The action force umount(umount -f) will attempt to kill all rpc_task even
umount operation may ultimately fail if some files remain open.
Consequently, if an action attempts to open a file, it can potentially
send two rpc_task to nfs server.

                   NFS CLIENT
thread1                             thread2
open("file")
...

   _nfs4_proc_open
    nfs4_run_open_task
     /* rpc_task1 */
     rpc_run_task
     rpc_wait_for_completion_task

                                    umount -f
                                    nfs_umount_begin
                                     rpc_killall_tasks
                                      rpc_signal_task
     rpc_task1 been wakeup
     and return -512

    ...
    nfs4_run_open_task
     /* rpc_task2 */
     rpc_run_task
     rpc_wait_for_completion_task

While processing an open request, nfsd will first attempt to find or
allocate an nfs4_openowner. If it finds an nfs4_openowner that is not
marked as NFS4_OO_CONFIRMED, this nfs4_openowner will released. Since
two rpc_task can attempt to open the same file simultaneously from the
client to server, and because two instances of nfsd can run
concurrently, this situation can lead to lots of memory leak.
Additionally, when we echo 0 to /proc/fs/nfsd/threads, warning will be
triggered.

Subject: [PATCH 2346/2948] nfs_common: must not hold RCU while calling
 nfsd_file_put_local

Move holding the RCU from nfs_to_nfsd_file_put_local to
nfs_to_nfsd_net_put.  It is the call to nfs_to->nfsd_serv_put that
requires the RCU anyway (the puts for nfsd_file and netns were
combined to avoid an extra indirect reference but that
micro-optimization isn't possible now).

This fixes xfstests generic/013 and it triggering:

"Voluntary context switch within RCU read-side critical section!"

Subject: [PATCH 2347/2948] nfsd: allow for up to 32 callback session slots

nfsd currently only uses a single slot in the callback channel, which is
proving to be a bottleneck in some cases. Widen the callback channel to
a max of 32 slots (subject to the client's target_maxreqs value).

Change the cb_holds_slot boolean to an integer that tracks the current
slot number (with -1 meaning "unassigned").  Move the callback slot
tracking info into the session. Add a new u32 that acts as a bitmap to
track which slots are in use, and a u32 to track the latest callback
target_slotid that the client reports. To protect the new fields, add
a new per-session spinlock (the se_lock). Fix nfsd41_cb_get_slot to always
search for the lowest slotid (using ffs()).

Finally, convert the session->se_cb_seq_nr field into an array of
ints and add the necessary handling to ensure that the seqids get
reset when the slot table grows after shrinking.

Subject: [PATCH 2348/2948] block: fix uaf for flush rq while iterating tags

blk_mq_clear_flush_rq_mapping() is not called during scsi probe, by
checking blk_queue_init_done(). However, QUEUE_FLAG_INIT_DONE is cleared
in del_gendisk by commit aec89dc5d421 ("block: keep q_usage_counter in
atomic mode after del_gendisk"), hence for disk like scsi, following
blk_mq_destroy_queue() will not clear flush rq from tags->rqs[] as well,
cause following uaf that is found by our syzkaller for v6.6:

Other than blk_mq_clear_flush_rq_mapping(), the flag is only used in
blk_register_queue() from initialization path, hence it's safe not to
clear the flag in del_gendisk. And since QUEUE_FLAG_REGISTERED already
make sure that queue should only be registered once, there is no need
to test the flag as well.

Subject: [PATCH 2350/2948] drm/i915/hdcp: Fix when the first read and write
 are retried

Make sure that the first read/write in hdcp2_authentication_key_exchange
are only retried when we have either DP/DPMST encoder connected,
since we do this to give docks and dp encoders some extra time to
get their HDCP DPCD registers ready only for DP/DPMST encoders as
this issue is only observed here no need to burden other encoders
with extra retries as this causes the HDMI connector to have some
other timing issue and fails HDCP authentication.

--v2
-Add intent of patch [Chaitanya]
-Add reasoning for loop [Jani]
-Make sure we forfiet the 50ms wait for non DP/DPMST encoders.

--v3
-Remove the is_dp_encoder check [Jani/Chaitanya]
-Make the commit message more clearer [Jani]

Subject: [PATCH 2354/2948] gfs2: Only defer deletes when we have an iopen
 glock

The mechanism to defer deleting unlinked inodes is tied to
delete_work_func(), which is tied to iopen glocks.  When we don't have
an iopen glock, we must carry out deletes immediately instead.

Fixes a NULL pointer dereference in gfs2_evict_inode().

Fixes: 8c21c2c71e66 ("gfs2: Call gfs2_queue_verify_delete from gfs2_evict_inode")

Subject: [PATCH 2356/2948] gfs2: Prevent inode creation race

When a request to evict an inode comes in over the network, we are
trying to grab an inode reference via the iopen glock's gl_object
pointer.  There is a very small probability that by the time such a
request comes in, inode creation hasn't completed and the I_NEW flag is
still set.  To deal with that, wait for the inode and then check if
inode creation was successful.

Subject: [PATCH 2358/2948] loop: Fix ABBA locking race

Current loop calls vfs_statfs() while holding the q->limits_lock. If
FS takes some locking in vfs_statfs callback, this may lead to ABBA
locking bug (at least, FAT fs has this issue actually).

So this patch calls vfs_statfs() outside q->limits_locks instead,
because looks like no reason to hold q->limits_locks while getting
discord configs.

Chain exists of:
  &sbi->fat_lock --> &q->q_usage_counter(io)#17 --> &q->limits_lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&q->limits_lock);
                               lock(&q->q_usage_counter(io)#17);
                               lock(&q->limits_lock);
  lock(&sbi->fat_lock);

Subject: [PATCH 2359/2948] Revert "nvme: make keep-alive synchronous
 operation"

This reverts commit d06923670b5a5f609603d4a9fee4dec02d38de9c.

It was realized that the fix implemented to contain the race condition
among the keep alive task and the fabric shutdown code path in the commit
d06923670b5ia ("nvme: make keep-alive synchronous operation") is not
optimal. The reason being keep-alive runs under the workqueue and making
it synchronous would waste a workqueue context.
Furthermore, we later found that the above race condition is a regression
caused due to the changes implemented in commit a54a93d0e359 ("nvme: move
stopping keep-alive into nvme_uninit_ctrl()"). So we decided to revert the
commit d06923670b5a ("nvme: make keep-alive synchronous operation") and
then fix the regression.

Subject: [PATCH 2360/2948] nvme-fabrics: fix kernel crash while shutting down
 controller

The nvme keep-alive operation, which executes at a periodic interval,
could potentially sneak in while shutting down a fabric controller.
This may lead to a race between the fabric controller admin queue
destroy code path (invoked while shutting down controller) and hw/hctx
queue dispatcher called from the nvme keep-alive async request queuing
operation. This race could lead to the kernel crash shown below:

Call Trace:
    autoremove_wake_function+0x0/0xbc (unreliable)
    __blk_mq_sched_dispatch_requests+0x114/0x24c
    blk_mq_sched_dispatch_requests+0x44/0x84
    blk_mq_run_hw_queue+0x140/0x220
    nvme_keep_alive_work+0xc8/0x19c [nvme_core]
    process_one_work+0x200/0x4e0
    worker_thread+0x340/0x504
    kthread+0x138/0x140
    start_kernel_thread+0x14/0x18

While shutting down fabric controller, if nvme keep-alive request sneaks
in then it would be flushed off. The nvme_keep_alive_end_io function is
then invoked to handle the end of the keep-alive operation which
decrements the admin->q_usage_counter and assuming this is the last/only
request in the admin queue then the admin->q_usage_counter becomes zero.
If that happens then blk-mq destroy queue operation (blk_mq_destroy_
queue()) which could be potentially running simultaneously on another
cpu (as this is the controller shutdown code path) would forward
progress and deletes the admin queue. So, now from this point onward
we are not supposed to access the admin queue resources. However the
issue here's that the nvme keep-alive thread running hw/hctx queue
dispatch operation hasn't yet finished its work and so it could still
potentially access the admin queue resource while the admin queue had
been already deleted and that causes the above crash.

The above kernel crash is regression caused due to changes implemented
in commit a54a93d0e359 ("nvme: move stopping keep-alive into
nvme_uninit_ctrl()"). Ideally we should stop keep-alive before destroyin
g the admin queue and freeing the admin tagset so that it wouldn't sneak
in during the shutdown operation. However we removed the keep alive stop
operation from the beginning of the controller shutdown code path in commit
a54a93d0e359 ("nvme: move stopping keep-alive into nvme_uninit_ctrl()")
and added it under nvme_uninit_ctrl() which executes very late in the
shutdown code path after the admin queue is destroyed and its tagset is
removed. So this change created the possibility of keep-alive sneaking in
and interfering with the shutdown operation and causing observed kernel
crash.

To fix the observed crash, we decided to move nvme_stop_keep_alive() from
nvme_uninit_ctrl() to nvme_remove_admin_tag_set(). This change would ensure
that we don't forward progress and delete the admin queue until the keep-
alive operation is finished (if it's in-flight) or cancelled and that would
help contain the race condition explained above and hence avoid the crash.

Moving nvme_stop_keep_alive() to nvme_remove_admin_tag_set() instead of
adding nvme_stop_keep_alive() to the beginning of the controller shutdown
code path in nvme_stop_ctrl(), as was the case earlier before commit
a54a93d0e359 ("nvme: move stopping keep-alive into nvme_uninit_ctrl()"),
would help save one callsite of nvme_stop_keep_alive().

Subject: [PATCH 2365/2948] block: Add extra checks in
 blk_validate_atomic_write_limits()

It is so far expected that the limits passed are valid.

In future atomic writes will be supported for stacked block devices, and
calculating the limits there will be complicated, so add extra sanity
checks to ensure that the values are always valid.

Subject: [PATCH 2366/2948] block: Support atomic writes limits for stacked
 devices

Allow stacked devices to support atomic writes by aggregating the minimum
capability of all bottom devices.

Flag BLK_FEAT_ATOMIC_WRITES_STACKED is set for stacked devices which
have been enabled to support atomic writes.

Some things to note on the implementation:
- For simplicity, all bottom devices must have same atomic write boundary
  value (if any)
- The atomic write boundary must be a power-of-2 already, but this
  restriction could be relaxed. Furthermore, it is now required that the
  chunk sectors for a top device must be aligned with this boundary.
- If a bottom device atomic write unit min/max are not aligned with the
  top device chunk sectors, the top device atomic write unit min/max are
  reduced to a value which works for the chunk sectors.

Set BLK_FEAT_ATOMIC_WRITES_STACKED to enable atomic writes. All other
stacked device request queue limits should automatically be set properly.
With regards to atomic write max bytes limit, this will be set at
hw_max_sectors and this is limited by the stripe width, which we want.

Subject: [PATCH 2370/2948] ASoC: amd: Fix build dependencies for
 `SND_SOC_AMD_PS`

The pci-ps module now must have `SND_SOC_ACPI_AMD_MATCH` selected
to reference the `snd_soc_acpi_amd_acp63_sdw_machines` symbol.

Subject: [PATCH 2371/2948] ACPI: processor_idle: Use acpi_idle_play_dead() for
 all C-states

Notice that acpi_processor_setup_cstates() can set state->enter_dead to acpi_idle_play_dead() for all C-states unconditionally and remove the
confusing C-state type check done before setting it.

No intentional functional impact.

Subject: [PATCH 2372/2948] Revert "block, bfq: merge bfq_release_process_ref()
 into bfq_put_cooperator()"

This reverts commit bc3b1e9e7c50e1de0f573eea3871db61dd4787de.

The bic is associated with sync_bfqq, and bfq_release_process_ref cannot
be put into bfq_put_cooperator.

Subject: [PATCH 2373/2948] block: blk-mq: fix uninit-value in
 blk_rq_prep_clone and refactor

Fix an issue detected by the `smatch` tool:

block/blk-mq.c:3314 blk_rq_prep_clone() error: uninitialized
symbol 'bio'.

This patch refactors `blk_rq_prep_clone()` to improve code
readability and ensure safety by addressing potential misuse of
the `bio` variable:

- Move the bio_put(bio); call to the bio_ctr error handling block,
  which is the only place where it can be triggered.
- Move the bio variable into the __rq_for_each_bio loop scope.
  This change removes the need to set bio to NULL at the loop's
  end.

discussion on why bio remains uninitialized:
https://lore.kernel.org/lkml/20241004141037.43277-1-surajsonawane0215@gmail.com

Summary of above discussion:
- I pointed out that `bio` can remain uninitialized if the
  allocation with `bio_alloc_clone` fails.
- Keith Busch explained that `bio` is initialized to `NULL` when
  `bio_alloc_clone()` fails, preventing uninitialized usage.
- John Garry questioned whether `rq_src->bio` being `NULL` could
  leave `bio` uninitialized. Keith clarified that in such cases,
  `bio` is not referenced, so it does not need initialization.
- Christoph Hellwig recommended code improvements:
 - move the bio_put to the bio_ctr error handling, which is the only
   case where it can happen
 - move the bio variable into the __rq_for_each_bio scope, which
   also removed the need to zero it at the end of the loop

These changes enhance code clarity, address static analysis tool
warnings, and make the function more maintainable.

Subject: [PATCH 2385/2948] selftests/mount_setattr: Fix failures on 64K
 PAGE_SIZE kernels

Currently the mount_setattr_test fails on machines with a 64K PAGE_SIZE,
with errors such as:

  #  RUN           mount_setattr_idmapped.invalid_fd_negative ...
  mkfs.ext4: No space left on device while writing out and closing file system
  # mount_setattr_test.c:1055:invalid_fd_negative:Expected system("mkfs.ext4 -q /mnt/C/ext4.img") (256) == 0 (0)
  # invalid_fd_negative: Test terminated by assertion
  #          FAIL  mount_setattr_idmapped.invalid_fd_negative
  not ok 12 mount_setattr_idmapped.invalid_fd_negative

The code creates a 100,000 byte tmpfs:

	ASSERT_EQ(mount("testing", "/mnt", "tmpfs", MS_NOATIME | MS_NODEV,
			"size=100000,mode=700"), 0);

And then a little later creates a 2MB ext4 filesystem in that tmpfs:

	ASSERT_EQ(ftruncate(img_fd, 1024 * 2048), 0);
	ASSERT_EQ(system("mkfs.ext4 -q /mnt/C/ext4.img"), 0);

At first glance it seems like that should never work, after all 2MB is
larger than 100,000 bytes. However the filesystem image doesn't actually
occupy 2MB on "disk" (actually RAM, due to tmpfs). On 4K kernels the
ext4.img uses ~84KB of actual space (according to du), which just fits.

However on 64K PAGE_SIZE kernels the ext4.img takes at least 256KB,
which is too large to fit in the tmpfs, hence the errors.

It seems fraught to rely on the ext4.img taking less space on disk than
the allocated size, so instead create the tmpfs with a size of 2MB. With
that all 21 tests pass on 64K PAGE_SIZE kernels.

Subject: [PATCH 2395/2948] dm ioctl: rate limit a couple of ioctl based error
 messages

It is possible to spam the kernel log with a misbehaving user process that
is passing incorrect dm ioctls to /dev/mapper/control. Use a rate limit
on these error messages to reduce the noise.

These errors were hit when running the stress-ng's device test.

Subject: [PATCH 2401/2948] dm: add support for get_unique_id

This adds support to obtain a device's unique id through dm, similar to the
existing ioctl and persistent resevation handling.  We limit this to
single-target devices.

This enables knfsd to export pNFS SCSI luns that have been exported from
multipath devices.

Subject: [PATCH 2403/2948] dm-bufio: use kmalloc to allocate power-of-two
 sized buffers

Vlastimil Babka said [1] that kmalloc will return a power-of-two-aligned
buffer if it was called with a power-of-two size. So, we can use kmalloc
instead of our own slab cache in dm-bufio. Note that the code for the
slab cache was not removed because dm-bufio supports non-power-of-two
buffer sizes.

 accesses for Extigy and Mbox devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A bogus device can provide a bNumConfigurations value that exceeds the
initial value used in usb_get_configuration for allocating dev->config.

This can lead to out-of-bounds accesses later, e.g. in
usb_destroy_configuration.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since ttm_bo_move_null() is exactly the same as ttm_resource_free() +
ttm_bo_assign_mem(), we use ttm_bo_move_null() for the GTT --> SYSTEM
move case too. Then the code is more consistent as the SYSTEM --> GTT
move case.

[Why]
No check on head pipe during the dml to dc hw mapping will allow illegal
pipe usage. This will result in a wrong pipe topology to cause mpcc tree
totally mess up then cause a display hang.

[How]
Avoid to use the pipe is head in all check and avoid ODM slice during
preferred pipe check.

Subject: [PATCH 2416/2948] drm/amd/display: Ignore scalar validation failure
 if pipe is phantom

[Why]
There are some pipe scaler validation failure when the pipe is phantom
and causes crash in DML validation. Since, scalar parameters are not
as important in phantom pipe and we require this plane to do successful
MCLK switches, the failure condition can be ignored.

[How]
Ignore scalar validation failure if the pipe validation is marked as
phantom pipe.

Subject: [PATCH 2417/2948] drm/amd/display: Fix handling of plane refcount

[Why]
The mechanism to backup and restore plane states doesn't maintain
refcount, which can cause issues if the refcount of the plane changes
in between backup and restore operations, such as memory leaks if the
refcount was supposed to go down, or double frees / invalid memory
accesses if the refcount was supposed to go up.

[How]
Cache and re-apply current refcount when restoring plane states.

Subject: [PATCH 2418/2948] drm/amd/display: Enable Request rate limiter during
 C-State on dcn401

[WHY]
When C-State entry is requested, the rate limiter will be disabled
which can result in high contention in the DCHUB return path.

[HOW]
Enable the rate limiter during C-state requests to prevent contention.

[Why]
Add public API to obtain number of taps in SPL.

[How]
Isolate function to calculate recout, ratios and viewport before
calculating taps. Call function in both public taps API call and private
scaling call.

Subject: [PATCH 2420/2948] drm/amd/display: Populate Power Profile In Case of
 Early Return

Early return possible if context has no clk_mgr.
This will lead to an invalid power profile being returned
which looks identical to a profile with the lowest power level.
Add back logic that populated the power profile and overwrite
the value if needed.

Subject: [PATCH 2421/2948] drm/amd/display: allow chroma 1:1 scaling when
 sharpness is off

[Why]
SPL code forces taps to 1 when ratio is 1:1 and sharpness is off
But for chroma 1:1, need taps > 1 to handle cositing

[How]
Do not force chroma taps to 1 when ratio is 1:1 for YUV420
Remove 420_CHROMA_BYPASS mode for scaler

Subject: [PATCH 2422/2948] drm/amd/display: Remove PIPE_DTO_SRC_SEL
 programming from set_dtbclk_dto

There are cases where an OTG is remapped from driving a regular HDMI
display to a DP/eDP display. There are also cases where DTBCLK needs to
be enabled for HPO, but DTBCLK DTO programming may be done while OTG is
still enabled which is dangerous as the PIPE_DTO_SRC_SEL programming may
change the pixel clock generator source for a mapped and running OTG and
cause it to hang.

Remove the PIPE_DTO_SRC_SEL programming from this sequence since it is
already done in program_pixel_clk(). Additionally, make sure that
program_pixel_clk sets DTBCLK DTO as source for special HDMI cases.

Subject: [PATCH 2427/2948] drm/amdkfd: make sure ring buffer is flushed before
 update wptr
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In a consecutive packet submission, for example unmap and query status,
when CP is reading wptr caused by unmap packet doorbell ring, if in some
case CP operates slower (e.g. doorbell_mode=1) and wptr has been updated
to next packet (query status), but the query status packet content has
not been flushed to memory yet, it will cause CP fetched stalled data.

Adding mb to ensure ring buffer has been updated before updating wptr.
Also adding a mb to ensure wptr updated before doorbell ring.

Subject: [PATCH 2429/2948] drm/amdgpu: Add init level for post reset reinit

When device needs to be reset before initialization, it's not required
for all IPs to be initialized before a reset. In such cases, it needs to
identify whether the IP/feature is initialized for the first time or
whether it's reinitialized after a reset.

Add RESET_RECOVERY init level to identify post reset reinitialization
phase. This only provides a device level identification, IP/features may
choose to track their state independently also.

Some in_reset checks are infact checking whether the state is
reinitialization after reset. Replace with reset_in_recovery calls to
identify that it's really checking for recovery stage after reset.

Subject: [PATCH 2432/2948] drm/radeon: Fix spurious unplug event on radeon
 HDMI

On several HP models (tested on HP 3125 and HP Probook 455 G2),
spurious unplug events are emitted upon login on Chrome OS.
This is likely due to the way Chrome OS restarts graphics
upon login, so it's possible it's an issue on other
distributions but not as common, though I haven't
reproduced the issue elsewhere.
Use logic from an earlier version of the merged change
(see link below) which iterates over connectors and finds
matching encoders, rather than the other way around.
Also fixes an issue with screen mirroring on Chrome OS.
I've deployed this patch on Fedora and did not observe
any regression on these devices.

Subject: [PATCH 2433/2948] drm/amd/display: Fix null check for
 pipe_ctx->plane_state in dcn20_program_pipe

This commit addresses a null pointer dereference issue in
dcn20_program_pipe(). Previously, commit 8e4ed3cf1642 ("drm/amd/display:
Add null check for pipe_ctx->plane_state in dcn20_program_pipe")
partially fixed the null pointer dereference issue. However, in
dcn20_update_dchubp_dpp(), the variable pipe_ctx is passed in, and
plane_state is accessed again through pipe_ctx. Multiple if statements
directly call attributes of plane_state, leading to potential null
pointer dereference issues. This patch adds necessary null checks to
ensure stability.

This commit addresses a null pointer dereference issue in

before accessing. This prevents a null pointer dereference.

 LoongArch

Clang on LoongArch (18+) appears to be unaffected by the bug causing
excessive stack usage in calculate_bandwidth(). But when building DC_FP
support the stack frame size can be as large as 2816 bytes, which causes
the FRAME_WARN build warnings. So on LoongArch we allow building DC with
clang, but disable DC_FP by default.

The help message is also updated.

The minimal alignment of an integral type may differ from its size,
hence is not safe to assume that an arbitrary freeptr_t (which is
basically an unsigned long) is always aligned to 4 or 8 bytes.

As nothing seems to require the additional alignment, it is safe to fix
this by relaxing the check to the actual minimum alignment of freeptr_t.

Subject: [PATCH 2441/2948] KVM: arm64: vgic: Make vgic_get_irq() more robust

vgic_get_irq() has an awkward signature, as it takes both a kvm
*and* a vcpu, where the vcpu is allowed to be NULL if the INTID
being looked up is a global interrupt (SPI or LPI).

This leads to potentially problematic situations where the INTID
passed is a private interrupt, but that there is no vcpu.

In order to make things less ambiguous, let have *two* helpers
instead:

- vgic_get_irq(struct kvm *kvm, u32 intid), which is only concerned
  with *global* interrupts, as indicated by the lack of vcpu.

- vgic_get_vcpu_irq(struct kvm_vcpu *vcpu, u32 intid), which can
  return *any* interrupt class, but must have of course a non-NULL
  vcpu.

Most of the code nicely falls under one or the other situations,
except for a couple of cases (close to the UABI or in the debug code)
where we have to distinguish between the two cases.

Subject: [PATCH 2443/2948] KVM: arm64: vgic-its: Add stronger type-checking to
 the ITS entry sizes

The ITS ABI infrastructure allows for some pretty lax code, where
the size of the data doesn't have to match the size of the entry,
potentially leading to a collection of interesting bugs.

Commit 7fe28d7e68f9 ("KVM: arm64: vgic-its: Add a data length check
in vgic_its_save_*") added some checks, but starts by implicitly
casting all writes to a 64bit value, hiding some of the issues.

Instead, introduce macros that will check the data type actually used
for dealing with the table entries. The macros are taking a symbolic
entry type that is used to fetch the size of the entry type for the
current ABI. This immediately catches a couple of low-impact gotchas
(zero values that are implicitly 32bit), easy enough to fix.

Given that we currently only have a single ABI, hardcode a couple of
BUILD_BUG_ON()s that will fire if we use anything but a 64bit quantity,
and some (currently unreachable) fallback code that may become useful
one day.

Subject: [PATCH 2444/2948] KVM: arm64: Mark set_sysreg_masks() as inline to
 avoid build failure

When compiling with CONFIG_CC_OPTIMIZE_FOR_SIZE=y, set_sysreg_masks()
fails to compile thanks to:

	BUILD_BUG_ON(!__builtin_constant_p(sr));

as the compiler doesn't identify sr as a constant, despite all the
callers passing constants.

Fix the issue by always inlining this function, which allows GCC to
do the right thing.

Subject: [PATCH 2445/2948] KVM: arm64: Ignore PMCNTENSET_EL0 while checking
 for overflow status

DDI0487K.a D13.3.1 describes the PMU overflow condition, which evaluates
to true if any counter's global enable (PMCR_EL0.E), overflow flag
(PMOVSSET_EL0[n]), and interrupt enable (PMINTENSET_EL1[n]) are all 1.
Of note, this does not require a counter to be enabled
(i.e. PMCNTENSET_EL0[n] = 1) to generate an overflow.

Align kvm_pmu_overflow_status() with the reality of the architecture
and stop using PMCNTENSET_EL0 as part of the overflow condition. The
bug was discovered while running an SBSA PMU test [*], which only sets
PMCR.E, PMOVSSET<0>, PMINTENSET<0>, and expects an overflow interrupt.

Subject: [PATCH 2446/2948] KVM: arm64: Use MDCR_EL2.HPME to evaluate overflow
 of hyp counters

The 'global enable control' (as it is termed in the architecture) for
counters reserved by EL2 is MDCR_EL2.HPME. Use that instead of
PMCR_EL0.E when evaluating the overflow state for hyp counters.

Change the return value to a bool while at it, which better reflects the
fact that the overflow state is a shared signal and not a per-counter
property.

Subject: [PATCH 2449/2948] gpio: exar: set value when external pull-up or
 pull-down is present

Setting GPIO direction = high, sometimes results in GPIO value = 0.

If a GPIO is pulled high, the following construction results in the
value being 0 when the desired value is 1:

$ echo "high" > /sys/class/gpio/gpio336/direction
$ cat /sys/class/gpio/gpio336/value
0

Before the GPIO direction is changed from an input to an output,
exar_set_value() is called with value = 1, but since the GPIO is an
input when exar_set_value() is called, _regmap_update_bits() reads a 1
due to an external pull-up.  regmap_set_bits() sets force_write =
false, so the value (1) is not written.  When the direction is then
changed, the GPIO becomes an output with the value of 0 (the hardware
default).

regmap_write_bits() sets force_write = true, so the value is always
written by exar_set_value() and an external pull-up doesn't affect the
outcome of setting direction = high.

The same can happen when a GPIO is pulled low, but the scenario is a
little more complicated.

$ echo high > /sys/class/gpio/gpio351/direction
$ cat /sys/class/gpio/gpio351/value
1

$ echo in > /sys/class/gpio/gpio351/direction
$ cat /sys/class/gpio/gpio351/value
0

$ echo low > /sys/class/gpio/gpio351/direction

Subject: [PATCH 2450/2948] iomap: warn on zero range of a post-eof folio

iomap_zero_range() uses buffered writes for manual zeroing, no
longer updates i_size for such writes, but is still explicitly
called for post-eof ranges. The historical use case for this is
zeroing post-eof speculative preallocation on extending writes from
XFS. However, XFS also recently changed to convert all post-eof
delalloc mappings to unwritten in the iomap_begin() handler, which
means it now never expects manual zeroing of post-eof mappings. In
other words, all post-eof mappings should be reported as holes or
unwritten.

This is a subtle dependency that can be hard to detect if violated
because associated codepaths are likely to update i_size after folio
locks are dropped, but before writeback happens to occur. For
example, if XFS reverts back to some form of manual zeroing of
post-eof blocks on write extension, writeback of those zeroed folios
will now race with the presumed i_size update from the subsequent
buffered write.

Since iomap_zero_range() can't correctly zero post-eof mappings
beyond EOF without updating i_size, warn if this ever occurs. This
serves as minimal indication that if this use case is reintroduced
by a filesystem, iomap_zero_range() might need to reconsider i_size
updates for write extending use cases.

Subject: [PATCH 2451/2948] iomap: reset per-iter state on non-error iter
 advances

iomap_iter_advance() zeroes the processed and mapping fields on
every non-error iteration except for the last expected iteration
(i.e. return 0 expected to terminate the iteration loop). This
appears to be circumstantial as nothing currently relies on these
fields after the final iteration.

Therefore to better faciliate iomap_iter reuse in subsequent
patches, update iomap_iter_advance() to always reset per-iteration
state on successful completion.

Subject: [PATCH 2453/2948] iomap: elide flush from partial eof zero range

iomap zero range flushes pagecache in certain situations to
determine which parts of the range might require zeroing if dirty
data is present in pagecache. The kernel robot recently reported a
regression associated with this flushing in the following stress-ng
workload on XFS:

stress-ng --timeout 60 --times --verify --metrics --no-rand-seed --metamix 64

This workload involves repeated small, strided, extending writes. On
XFS, this produces a pattern of post-eof speculative preallocation,
conversion of preallocation from delalloc to unwritten, dirtying
pagecache over newly unwritten blocks, and then rinse and repeat
from the new EOF. This leads to repetitive flushing of the EOF folio
via the zero range call XFS uses for writes that start beyond
current EOF.

To mitigate this problem, special case EOF block zeroing to prefer
zeroing the folio over a flush when the EOF folio is already dirty.
To do this, split out and open code handling of an unaligned start
offset. This brings most of the performance back by avoiding flushes
on zero range calls via write and truncate extension operations. The
flush doesn't occur in these situations because the entire range is
post-eof and therefore the folio that overlaps EOF is the only one
in the range.

Subject: [PATCH 2458/2948] ALSA: pcm: Add sanity NULL check for the default
 mmap fault handler

A driver might allow the mmap access before initializing its
runtime->dma_area properly.  Add a proper NULL check before passing to
virt_to_page() for avoiding a panic.

Subject: [PATCH 2459/2948] s390/debug: Pass in and enforce output buffer size
 for format handlers

The s390dbf format handler rely on being passed an output buffer sized
such that their output will always fit and then use plain sprintf() to
write to it. While only supplied data from other kernel components this
still potentially allows buffer overwrite if callers are not careful.
Instead just pass in the size of the output buffer and use scnprintf()
instead of sprintf() and strscpy() instead of strcpy(). The latter also
allows us to get rid of a separate strlen() call.

Subject: [PATCH 2461/2948] s390/stacktrace: Use break instead of return
 statement

arch_stack_walk_user_common() contains a return statement instead of a
break statement in case store_ip() fails while trying to store a callchain
entry of a user space process.
This may lead to a missing pagefault_enable() call.

If this happens any subsequent page fault of the process won't be resolved
by the page fault handler and this in turn will lead to the process being
killed.

Use a break instead of a return statement to fix this.

If the page has been exported, do not re-import it. Imports should
only be triggered by the guest. The guest will import the page
automatically when it will need it again, there is no advantage in
importing it manually.

Moreover, vfio_pin_pages() will take an extra reference on the page and
thus will cause the import to always fail. The extra reference would be
dropped only after pointlessly trying to import the page.

Subject: [PATCH 2463/2948] s390/cpum_sf: Simplify release of SDBs and SDBTs

Free_sampling_buffer() releases the Sampling Data Buffers (SDBs)
and Sampling Data Buffer Table (SDBTs) allocated at event
initialization. Both buffers are of PAGE_SIZE bytes. Each SDBT
consists of 512 entries. The first 511 entries point to SDBs
the last entry points to a successor SDBT. The last SDBT in
the list points to the origin of all SDBTs. SDBTs do not
contain holes, that is an entry always points to a SDB.
If less than 511 SDBs have been allocation, the last entry
points to the origin SDBT.

Simplify the release of the SDBs and SDBTs, walk along the
SDBT chain, release SDBs and SDBTs and stop when reaching
the origin again.

Subject: [PATCH 2464/2948] s390/entry: Mark IRQ entries to fix stack depot
 warnings

The stack depot filters out everything outside of the top interrupt
context as an uninteresting or irrelevant part of the stack traces. This
helps with stack trace de-duplication, avoiding an explosion of saved
stack traces that share the same IRQ context code path but originate
from different randomly interrupted points, eventually exhausting the
stack depot.

Filtering uses in_irqentry_text() to identify functions within the
.irqentry.text and .softirqentry.text sections, which then become the
last stack trace entries being saved.

While __do_softirq() is placed into the .softirqentry.text section by
common code, populating .irqentry.text is architecture-specific.

Currently, the .irqentry.text section on s390 is empty, which prevents
stack depot filtering and de-duplication and could result in warnings
like:

Stack depot reached limit capacity
WARNING: CPU: 0 PID: 286113 at lib/stackdepot.c:252 depot_alloc_stack+0x39a/0x3c8

with PREEMPT and KASAN enabled.

Fix this by moving the IO/EXT interrupt handlers from .kprobes.text into
the .irqentry.text section and updating the kprobes blacklist to include
the .irqentry.text section.

This is done only for asynchronous interrupts and explicitly not for
program checks, which are synchronous and where the context beyond the
program check is important to preserve. Despite machine checks being
somewhat in between, they are extremely rare, and preserving context
when possible is also of value.

SVCs and Restart Interrupts are not relevant, one being always at the
boundary to user space and the other being a one-time thing.

IRQ entries filtering is also optionally used in ftrace function graph,
where the same logic applies.

Subject: [PATCH 2465/2948] RISC-V: Add Svade and Svadu Extensions Support

Svade and Svadu extensions represent two schemes for managing the PTE A/D
bits. When the PTE A/D bits need to be set, Svade extension intdicates
that a related page fault will be raised. In contrast, the Svadu extension
supports hardware updating of PTE A/D bits. Since the Svade extension is
mandatory and the Svadu extension is optional in RVA23 profile, by default
the M-mode firmware will enable the Svadu extension in the menvcfg CSR
when only Svadu is present in DT.

This patch detects Svade and Svadu extensions from DT and adds
arch_has_hw_pte_young() to enable optimization in MGLRU and
__wp_page_copy_user() when we have the PTE A/D bits hardware updating
support.

Subject: [PATCH 2469/2948] 9p/xen: fix init sequence

Large amount of mount hangs observed during hotplugging of 9pfs devices. The
9pfs Xen driver attempts to initialize itself more than once, causing the
frontend and backend to disagree: the backend listens on a channel that the
frontend does not send on, resulting in stalled processing.

Only allow initialization of 9p frontend once.

Subject: [PATCH 2470/2948] spi-imx: prevent overflow when estimating transfer
 time

The words delay is computed by multiplying two unsigned ints
and by adding up the result to a u64 variable.

The multiplication, however, is performed with 32bit math
thus losing data when the actual result is larger than UINT32_MAX.

Fix the operation by casting the first operand to u64, thus forcing
the multiplication to be performed with 64bit math.

This fixes 1 OVERFLOW_BEFORE_WIDEN issue reported by Coverity

Subject: [PATCH 2474/2948] io_uring: limit local tw done

Instead of eagerly running all available local tw, limit the amount of
local tw done to the max of IO_LOCAL_TW_DEFAULT_MAX (20) or wait_nr. The
value of 20 is chosen as a reasonable heuristic to allow enough work
batching but also keep latency down.

Add a retry_llist that maintains a list of local tw that couldn't be
done in time. No synchronisation is needed since it is only modified
within the task context.

A previous commit added file support for nop, but it only initializes
nop->fd if IORING_NOP_FIXED_FILE is set. That check should be
IORING_NOP_FILE. Fix up the condition in nop preparation, and initialize
it to a sane value even if we're not going to be directly using it.

While in there, do the same thing for the nop->buffer field.

Subject: [PATCH 2477/2948] PCI/pwrctl: Use of_platform_device_create() to
 create pwrctl devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The of_platform_populate() API creates platform devices by descending
through the children of the parent node. But it provides no control over
the child nodes, which makes it difficult to add checks for the child
nodes in the future.

Use of_platform_device_create() and for_each_child_of_node_scoped() to make
it possible to add checks for each node before creating the platform
device.

Subject: [PATCH 2478/2948] PCI/pwrctl: Create pwrctl device only if at least
 one power supply is present
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, pwrctl devices are created if the corresponding PCI nodes are
defined in devicetree. But this is not correct, because not all PCI nodes
require pwrctl support. Pwrctl comes into the picture only when the device
requires kernel to manage its power state. This can be determined using the
power supply properties present in the devicetree node of the device.

Add of_pci_supply_present() to check whether the devicetree contains at
least one power supply property for a device. If one is present, create a
pwrctl device for that PCI node.

Subject: [PATCH 2479/2948] PCI/pwrctl: Ensure that pwrctl drivers are probed
 before PCI client drivers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As per the kernel device driver model, a pwrctl device is the supplier for
the PCI device, but the device link that enforces the supplier-consumer
relationship was previously created by the pwrctl driver. Therefore, the
driver model didn't prevent probing PCI client drivers before probing the
corresponding pwrctl drivers. This may lead to a race condition if the PCI
device was already powered on by the bootloader (before the pwrctl driver).

If the bootloader did not power on the PCI device, this wouldn't create any
problem as the pwrctl driver will be the one powering on the device, so the
PCI client driver always gets probed afterward. But if the device was
already powered on, then the device will be seen by the PCI core and the
PCI client driver may get probed before its pwrctl driver. This creates a
race condition as the pwrctl driver may change the device power state while
the device is being accessed by the client driver.

One such issue was already reported on the Qcom X13s platform with the WLAN
device and fixed with a hack in the WCN pwrseq driver by a9aaf1ff88a8
("power: sequencing: request the WLAN enable GPIO as-is").

A cleaner way to fix the above mentioned race condition is to ensure that
the pwrctl drivers are always probed before the client drivers.

If the PCI device is associated with a pwrctl platform device with a power
supply, add a device link between the PCI device and the pwrctl device
before device_attach() in pci_bus_add_device().

Note that there is no need to explicitly remove the device link as that
will be taken care of by the driver core when the PCI device gets removed.

There is no need to iterate over all children of the pwrctl device parent
to remove the pwrctl device. Since the pwrctl device associated with the
PCI device can be found using of_find_device_by_node() API, use it directly
instead.

Any pwrctl devices lying around without getting associated with the PCI
devices will be removed once their parent device gets removed.

To slightly reduce confusion between "pwrctl" (the power controller and
power sequencing framework) and "bwctrl" (the bandwidth controller),
rename "pwrctl" to "pwrctrl" so they use the same "ctrl" suffix.

Rename drivers/pci/pwrctl/ to drivers/pci/pwrctrl/, including the related
MAINTAINERS, include file (include/linux/pci-pwrctl.h), Makefile, and
Kconfig changes.

This is the minimal rename of files only.  A subsequent commit will rename
functions and data structures.

Subject: [PATCH 2484/2948] f2fs: replace deprecated strcpy with strscpy

strcpy is deprecated. Kernel docs recommend replacing strcpy with
strscpy. The function strcpy() return value isn't used so there
shouldn't be an issue replacing with the safer alternative strscpy.

Subject: [PATCH 2486/2948] f2fs: clean up w/ F2FS_{BLK_TO_BYTES,BTYES_TO_BLK}

f2fs doesn't support different blksize in one instance, so
bytes_to_blks() and blks_to_bytes() are equal to F2FS_BYTES_TO_BLK
and F2FS_BLK_TO_BYTES, let's use F2FS_BYTES_TO_BLK/F2FS_BLK_TO_BYTES
instead for cleanup.

Subject: [PATCH 2487/2948] f2fs: fix to adjust appropriate length for fiemap

If user give a file size as "length" parameter for fiemap
operations, but if this size is non-block size aligned,
it will show 2 segments fiemap results even this whole file
is contiguous on disk, such as the following results:

 ./f2fs_io fiemap 0 19034 ylog/analyzer.py
Fiemap: offset = 0 len = 19034
        logical addr.    physical addr.   length           flags

after this patch:
./f2fs_io fiemap 0 19034 ylog/analyzer.py
Fiemap: offset = 0 len = 19034
    logical addr.    physical addr.   length           flags

     0: [0..39]:         139272..139311      40 0x1001

There are two problems:
- continuous extent is split to two
- FIEMAP_EXTENT_LAST is missing in last extent

The root cause is: if upper boundary of inquiry crosses extent,
f2fs_map_blocks() will truncate length of returned extent to
F2FS_BYTES_TO_BLK(len), and also, it will stop to query latter
extent or hole to make sure current extent is last or not.

In order to fix this issue, once we found an extent locates
in the end of inquiry range by f2fs_map_blocks(), we need to
expand inquiry range to requiry.

Subject: [PATCH 2490/2948] f2fs: fix changing cursegs if recovery fails on
 zoned device

Fsync data recovery attempts to check and fix write pointer consistency
of cursegs and all other zones. If the write pointers of cursegs are
unaligned, cursegs are changed to new sections.

If recovery fails, zone write pointers are still checked and fixed,
but the latest checkpoint cannot be written back. Additionally, retry-
mount skips recovery and rolls back to reuse the old cursegs whose
zones are already finished. This can lead to unaligned write later.

This patch addresses the issue by leaving writer pointers untouched if
recovery fails. When retry-mount is performed, cursegs and other zones
are checked and fixed after skipping recovery.

If a previous ufence is not signalled, vm_bind will return -EBUSY.
Delaying the modification of ufence->signalled can cause issues if the
UMD reuses the same ufence so update ufence->signalled before waking up

If fs corruption occurs in f2fs_new_node_page(), let's print

Meanwhile, it updates to record ERROR_INCONSISTENT_NAT instead
of ERROR_INVALID_BLKADDR if blkaddr in nat entry is not
NULL_ADDR which means nat bitmap and nat entry is inconsistent.

Subject: [PATCH 2495/2948] f2fs: fix to shrink read extent node in batches

We use rwlock to protect core structure data of extent tree during
its shrink, however, if there is a huge number of extent nodes in
extent tree, during shrink of extent tree, it may hold rwlock for
a very long time, which may trigger kernel hang issue.

This patch fixes to shrink read extent node in batches, so that,
critical region of the rwlock can be shrunk to avoid its extreme
long time hold.

Subject: [PATCH 2498/2948] arm64: disable ARCH_CORRECT_STACKTRACE_ON_KRETPROBE
 tests

The kprobes_test suite's test_stacktrace_on_nested_kretprobe() test
currently fails on arm64, e.g.

| KTAP version 1
| 1..1
|     KTAP version 1
|     # Subtest: kprobes_test
|     # module: test_kprobes
|     1..7
|     ok 1 test_kprobe
|     ok 2 test_kprobes
|     ok 3 test_kprobe_missed
|     ok 4 test_kretprobe
|     ok 5 test_kretprobes
|     ok 6 test_stacktrace_on_kretprobe
|     # test_stacktrace_on_nested_kretprobe: EXPECTATION FAILED at lib/test_kprobes.c:327
|     Expected stack_buf[i + 1] == target_return_address[1], but
|         stack_buf[i + 1] == -96519936577004 (0xffffa83733777214)
|         target_return_address[1] == -96519936577136 (0xffffa83733777190)
|     # test_stacktrace_on_nested_kretprobe: EXPECTATION FAILED at lib/test_kprobes.c:338
|     Expected stack_buf[1] == target_return_address[1], but
|         stack_buf[1] == -96519936577004 (0xffffa83733777214)
|         target_return_address[1] == -96519936577136 (0xffffa83733777190)
|     not ok 7 test_stacktrace_on_nested_kretprobe
| # kprobes_test: pass:6 fail:1 skip:0 total:7
| # Totals: pass:6 fail:1 skip:0 total:7
| not ok 1 kprobes_test

The test assumes that when a stacktrace straddles an exception boundary,
no necessary entries will be omitted and no extraneous entries will be
reported, and when unwinding from a kretprobed callee, the next entry in
the trace will be its immediate caller (whether kretprobed or not).

Recently the arm64 stacktrace code was changed to always report the LR
at an exception boundary, where we don't know whether the LR is live.
In the case of the kretprobe trampoline the LR is not live at the time
the stacktrace is performed, and so the entry in the trace for the LR is
extraneous. This can be seen if a call to show_stack() is added to
stacktrace_internal_return_handler():

| Call trace:
|  show_stack+0x18/0x30 (C)
|  stacktrace_internal_return_handler+0x130/0x43c
|  __kretprobe_trampoline_handler+0xa0/0x130
|  kretprobe_breakpoint_handler+0x50/0x70
|  call_break_hook+0x74/0x8c
|  brk_handler+0x1c/0x60
|  do_debug_exception+0x68/0x114
|  el1_dbg+0x70/0x94
|  el1h_64_sync_handler+0xc4/0xe4
|  el1h_64_sync+0x6c/0x70
|  kprobe_stacktrace_target+0x34/0x48 (P)
|  kprobe_stacktrace_target+0x34/0x48 (LK) <-------- extra entry here
|  kprobe_stacktrace_driver+0x24/0x40 (K)
|  test_stacktrace_on_nested_kretprobe+0x84/0x160
|  kunit_try_run_case+0x6c/0x160
|  kunit_generic_run_threadfn_adapter+0x28/0x4c
|  kthread+0x110/0x114
|  ret_from_fork+0x10/0x20

This breaks test_stacktrace_on_nested_kretprobe() because while the
caller (kprobe_stacktrace_driver()) appears in the trace, it doesn't
occur *immediately* after the first instance of callee
(kprobe_stacktrace_target()).

While this behaviour is unfortunate for the kretprobes tests, the
behaviour is desirable elsewhere (e.g. anywhere a human will read the
trace), and is otherwise not harmful.

For the moment, deselect ARCH_CORRECT_STACKTRACE_ON_KRETPROBE on arm64
to disable the tests which depend on this behaviour. With
ARCH_CORRECT_STACKTRACE_ON_KRETPROBE deselected, the remaining tests
work as expected, e.g.

| KTAP version 1
| 1..1
|     KTAP version 1
|     # Subtest: kprobes_test
|     # module: test_kprobes
|     1..5
|     ok 1 test_kprobe
|     ok 2 test_kprobes
|     ok 3 test_kprobe_missed
|     ok 4 test_kretprobe
|     ok 5 test_kretprobes
| # kprobes_test: pass:5 fail:0 skip:0 total:5
| # Totals: pass:5 fail:0 skip:0 total:5
| ok 1 kprobes_test

In future we have several options to improve matters, e.g.

* Add metadata and update arm64's unwinder to skip the LR in this case.
  This is likely to happen as part of work for RELIABLE_STACKTRACE for
  other reasons, and might solve this case by coincidence.

* Modify the kretprobes tests to only require that the caller appears in
  the trace after the callee, rather than requiring that it is
  *immediately* after the callee. We might want separate
  strict/not-strict options for this.

* Use reliable stacktrace for these tests, so that architectures which
  cannot unwind across exception boundaries can explicitly handle this
  by returning an error.

Subject: [PATCH 2502/2948] drm/amd/pm: Remove arcturus min power limit

As per power team, there is no need to impose a lower bound on arcturus
power limit. Any unreasonable limit set will result in frequent
throttling.

Subject: [PATCH 2504/2948] drm/amdgpu: Add sysfs interface for vcn reset mask
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add the sysfs interface for vcn:
vcn_reset_mask

The interface is read-only and show the resets supported by the IP.
For example, full adapter reset (mode1/mode2/BACO/etc),
soft reset, queue reset, and pipe reset.

V2: the sysfs node returns a text string instead of some flags (Christian)

V2: the sysfs node returns a text string instead of some flags (Christian)
v3: add a generic helper which takes the ring as parameter
    and print the strings in the order they are applied (Christian)

    check amdgpu_gpu_recovery  before creating sysfs file itself,
    and initialize supported_reset_types in IP version files (Lijo)
v4: s/sdma/vcn/ in the reset mask setup

Subject: [PATCH 2506/2948] drm/amdgpu/vcn: reset fw_shared when VCPU buffers
 corrupted on vcn v4.0.3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It is not necessarily corrupted. When there is RAS fatal error, device
memory access is blocked. Hence vcpu bo cannot be saved to system memory
as in a regular suspend sequence before going for reset. In other full
device reset cases, that gets saved and restored during resume.

v2: Remove redundant code like vcn_v4_0 did
v2: Refine commit message
v3: Drop the volatile
v3: Refine commit message

[  +0.000013] ==================================================================

The issue reproduced on VG20 during the IGT pci_unplug test.
The root cause of the issue is that the function drm_sched_fini is called before drm_sched_entity_kill.
In drm_sched_fini, the drm_sched_rq structure is freed, but this structure is later accessed by
each entity within the run queue, leading to invalid memory access.
To resolve this, the order of cleanup calls is updated:

    Before:
        amdgpu_fence_driver_sw_fini
        amdgpu_device_ip_fini

    After:
        amdgpu_device_ip_fini
        amdgpu_fence_driver_sw_fini

This updated order ensures that all entities in the IPs are cleaned up first, followed by proper
cleanup of the schedulers.

Additional Investigation:

During debugging, another issue was identified in the amdgpu_vce_sw_fini function. The vce.vcpu_bo
buffer must be freed only as the final step in the cleanup process to prevent any premature
access during earlier cleanup stages.

v2: Using Christian suggestion call drm_sched_entity_destroy before drm_sched_fini.

Subject: [PATCH 2512/2948] xfs: remove unknown compat feature check in
 superblock write validation

Compat features are new features that older kernels can safely ignore,
allowing read-write mounts without issues. The current sb write validation
implementation returns -EFSCORRUPTED for unknown compat features,
preventing filesystem write operations and contradicting the feature's
definition.

Additionally, if the mounted image is unclean, the log recovery may need
to write to the superblock. Returning an error for unknown compat features
during sb write validation can cause mount failures.

Although XFS currently does not use compat feature flags, this issue
affects current kernels' ability to mount images that may use compat
feature flags in the future.

Since superblock read validation already warns about unknown compat

Subject: [PATCH 2513/2948] xfs: fix sparse inode limits on runt AG

The runt AG at the end of a filesystem is almost always smaller than
the mp->m_sb.sb_agblocks. Unfortunately, when setting the max_agbno
limit for the inode chunk allocation, we do not take this into
account. This means we can allocate a sparse inode chunk that
overlaps beyond the end of an AG. When we go to allocate an inode
from that sparse chunk, the irec fails validation because the
agbno of the start of the irec is beyond valid limits for the runt
AG.

Prevent this from happening by taking into account the size of the
runt AG when allocating inode chunks. Also convert the various
checks for valid inode chunk agbnos to use xfs_ag_block_count()
so that they will also catch such issues in the future.

Subject: [PATCH 2514/2948] xfs: delalloc and quota softlimit timers are
 incoherent

I've been seeing this failure on during xfs/050 recently:

 XFS: Assertion failed: dst->d_spc_timer != 0, file: fs/xfs/xfs_qm_syscalls.c, line: 435
....
 Call Trace:
  <TASK>
  xfs_qm_scall_getquota_fill_qc+0x2a2/0x2b0
  xfs_qm_scall_getquota_next+0x69/0xa0
  xfs_fs_get_nextdqblk+0x62/0xf0

  do_syscall_64+0x68/0x130
  entry_SYSCALL_64_after_hwframe+0x76/0x7e

It turns out that the _qmount call has silently been failing to
unmount and mount the filesystem, so when the softlimit is pushed
past with a buffered write, it is not getting synced to disk before
the next quota report is being run.

Hence when the quota report runs, we have 300 blocks of delalloc
data on an inode, with a soft limit of 200 blocks. XFS dquots
account delalloc reservations as used space, hence the dquot is over
the soft limit.

However, we don't update the soft limit timers until we do a
transactional update of the dquot. That is, the dquot sits over the
soft limit without a softlimit timer being started until writeback
occurs and the allocation modifies the dquot and we call
xfs_qm_adjust_dqtimers() from xfs_trans_apply_dquot_deltas() in
xfs_trans_commit() context.

This isn't really a problem, except for this debug code in
xfs_qm_scall_getquota_fill_qc():

        if (xfs_dquot_is_enforced(dqp) && dqp->q_id != 0) {
                if ((dst->d_space > dst->d_spc_softlimit) &&
                    (dst->d_spc_softlimit > 0)) {
                        ASSERT(dst->d_spc_timer != 0);
                }
....

It asserts taht if the used block count is over the soft limit,
it *must* have a soft limit timer running. This is clearly not
the case, because we haven't committed the delalloc space to disk
yet. Hence the soft limit is only exceeded temporarily in memory
(which isn't an issue) and we start the timer the moment we exceed
the soft limit in journalled metadata.

This debug was introduced in:

commit 0d5ad8383061fbc0a9804fbb98218750000fe032
Author: Supriya Wickrematillake <sup@sgi.com>
Date:   Wed May 15 22:44:44 1996 +0000

    initial checkin
    quotactl syscall functions.

The very first quota support commit back in 1996. This is zero-day
debug for Irix and, as it turns out, a zero-day bug in the debug
code because the delalloc code on Irix didn't update the softlimit
timers, either.

IOWs, this issue has been in the code for 28 years.

We obviously don't care if soft limit timers are a bit rubbery when
we have delalloc reservations in memory. Production systems running
quota reports have been exposed to this situation for 28 years and
nobody has noticed it, so the debug code is essentially worthless at
this point in time.

We also have the on-disk dquot verifiers checking that the soft
limit timer is running whenever the dquot is over the soft limit
before we write it to disk and after we read it from disk. These
aren't firing, so it is clear the issue is purely a temporary
in-memory incoherency that I never would have noticed had the test
not silently failed to unmount the filesystem.

Hence I'm simply going to trash this runtime debug because it isn't
useful in the slightest for catching quota bugs.

This is an ABBA deadlock where buffer IO completion is triggering a
forced shutdown with the buffer lock held. It is waiting for the CIL
to flush as part of the log force. The CIL flush is blocked doing
shutdown processing of all it's objects, trying to unpin a buffer
item. That requires taking the buffer lock....

For the CIL to be doing shutdown processing, the log must be marked
with XLOG_IO_ERROR, but that doesn't happen until after the log
force is issued. Hence for xfs_do_force_shutdown() to be forcing
the log on a shut down log, we must have had a racing
xlog_force_shutdown and xfs_force_shutdown like so:

p0			p1			CIL push

   			<holds buffer lock>
xlog_force_shutdown
  xfs_log_force
   test_and_set_bit(XLOG_IO_ERROR)
   						xlog_state_release_iclog()
						  sees XLOG_IO_ERROR
						  xlog_state_shutdown_callbacks
						    ....
						    xfs_buf_item_unpin
						    xfs_buf_lock
						    <blocks on buffer p1 holds>

   			xfs_force_shutdown
			  xfs_set_shutdown(mp) wins
			    xlog_force_shutdown
			      xfs_log_force
			        <blocks on CIL push>

  xfs_set_shutdown(mp) fails
  <shuts down rest of log>

The deadlock can be mitigated by avoiding the log force on the
second pass through xlog_force_shutdown. Do this by adding another
atomic state bit (XLOG_OP_PENDING_SHUTDOWN) that is set on entry to
xlog_force_shutdown() but doesn't mark the log as shutdown.

Subject: [PATCH 2518/2948] Fix a potential abuse of seq_printf() format string
 in drivers

Using device name as format string of seq_printf() is proned to
"Format string attack", opens possibility for exploitation.
Seq_puts() is safer and more efficient.

Subject: [PATCH 2520/2948] net/9p/usbg: allow building as standalone module

There is no reason only the usbg transport would not be its own module,
so make it tristate.

In particular, this fixes a couple of issues the current bool had:
- trans_usbg was apparently not compiled at all when NET_9P=m
- the workaround added in commit 2193ede180dd ("net/9p/usbg: fix
CONFIG_USB_GADGET dependency") became redundant because a tristate item
cannot be built-in when its dependency is a module, so we can depend on
USB_GADGET "normally" again.

There are currently some doubts about out-of-tree kernel modules licensed

using EXPORT_SYMBOL_GPL.

Clarify that "Proprietary" means anything non-GPL2 even though the
license might be an open source license. Also disambiguate "GPL

This idea was formed after noticing that new developers experience
certain difficulty to navigate within the multitude of different
debugging options in the Kernel and while there often is good
documentation for the tools, the developer has to know first that they
exist and where to find them.
Add a general debugging section to the Kernel documentation, as an
easily locatable entry point to other documentation and as a general
guideline for the topic.

+========================================
+
+This document serves as a general starting point and lookup for debugging
+device drivers.
+While this guide focuses on debugging that requires re-compiling the
+module/kernel, the :doc:`userspace debugging guide
+</process/debugging/userspace_debugging_guide>` will guide
+you through tools like dynamic debug, ftrace and other tools useful for
+debugging issues and behavior.
+For general debugging advice, see the :doc:`general advice document
+</process/debugging/index>`.
+
+.. contents::
+    :depth: 3
+
+The following sections show you the available tools.
+
+printk() & friends
+------------------
+
+These are derivatives of printf() with varying destinations and support for
+being dynamically turned on or off, or lack thereof.
+
+Simple printk()
+~~~~~~~~~~~~~~~
+
+The classic, can be used to great effect for quick and dirty development
+of new modules or to extract arbitrary necessary data for troubleshooting.
+
+Prerequisite: ``CONFIG_PRINTK`` (usually enabled by default)
+
+**Pros**:
+
+- No need to learn anything, simple to use
+- Easy to modify exactly to your needs (formatting of the data (See:
+  :doc:`/core-api/printk-formats`), visibility in the log)
+- Can cause delays in the execution of the code (beneficial to confirm whether
+  timing is a factor)
+
+**Cons**:
+
+- Requires rebuilding the kernel/module
+- Can cause delays in the execution of the code (which can cause issues to be
+  not reproducible)
+
+For the full documentation see :doc:`/core-api/printk-basics`
+
+Trace_printk
+~~~~~~~~~~~~
+
+Prerequisite: ``CONFIG_DYNAMIC_FTRACE`` & ``#include <linux/ftrace.h>``
+
+It is a tiny bit less comfortable to use than printk(), because you will have
+to read the messages from the trace file (See: :ref:`read_ftrace_log`
+instead of from the kernel log, but very useful when printk() adds unwanted
+delays into the code execution, causing issues to be flaky or hidden.)
+
+If the processing of this still causes timing issues then you can try
+trace_puts().
+
+For the full Documentation see trace_printk()
+
+dev_dbg
+~~~~~~~
+
+Print statement, which can be targeted by
+:ref:`process/debugging/userspace_debugging_guide:dynamic debug` that contains
+additional information about the device used within the context.
+
+**When is it appropriate to leave a debug print in the code?**
+
+Permanent debug statements have to be useful for a developer to troubleshoot
+driver misbehavior. Judging that is a bit more of an art than a science, but
+some guidelines are in the :ref:`Coding style guidelines
+<process/coding-style:13) printing kernel messages>`. In almost all cases the
+debug statements shouldn't be upstreamed, as a working driver is supposed to be
+silent.
+
+Custom printk
+~~~~~~~~~~~~~
+
+Example::
+
+  #define core_dbg(fmt, arg...) do { \
+	  if (core_debug) \
+		  printk(KERN_DEBUG pr_fmt("core: " fmt), ## arg); \
+	  } while (0)
+
+**When should you do this?**
+
+It is better to just use a pr_debug(), which can later be turned on/off with
+dynamic debug. Additionally, a lot of drivers activate these prints via a
+variable like ``core_debug`` set by a module parameter. However, Module
+parameters `are not recommended anymore
+<https://lore.kernel.org/all/2024032757-surcharge-grime-d3dd@gregkh>`_.
+
+Ftrace
+------
+
+Creating a custom Ftrace tracepoint
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A tracepoint adds a hook into your code that will be called and logged when the
+tracepoint is enabled. This can be used, for example, to trace hitting a
+conditional branch or to dump the internal state at specific points of the code
+flow during a debugging session.
+
+Here is a basic description of :ref:`how to implement new tracepoints
+<trace/tracepoints:usage>`.
+
+For the full event tracing documentation see :doc:`/trace/events`
+
+For the full Ftrace documentation see :doc:`/trace/ftrace`
+
+DebugFS
+-------
+
+Prerequisite: ``CONFIG_DEBUG_FS` & `#include <linux/debugfs.h>``
+
+DebugFS differs from the other approaches of debugging, as it doesn't write
+messages to the kernel log nor add traces to the code. Instead it allows the
+developer to handle a set of files.
+With these files you can either store values of variables or make
+register/memory dumps or you can make these files writable and modify
+values/settings in the driver.
+
+Possible use-cases among others:
+
+- Store register values
+- Keep track of variables
+- Store errors
+- Store settings
+- Toggle a setting like debug on/off
+- Error injection
+
+This is especially useful, when the size of a data dump would be hard to digest
+as part of the general kernel log (for example when dumping raw bitstream data)
+or when you are not interested in all the values all the time, but with the
+possibility to inspect them.
+
+The general idea is:
+
+- Create a directory during probe (``struct dentry *parent =
+  debugfs_create_dir("my_driver", NULL);``)
+- Create a file (``debugfs_create_u32("my_value", 444, parent, &my_variable);``)
+
+  - In this example the file is found in
+    ``/sys/kernel/debug/my_driver/my_value`` (with read permissions for
+    user/group/all)
+  - any read of the file will return the current contents of the variable
+    ``my_variable``
+
+- Clean up the directory when removing the device
+  (``debugfs_remove_recursive(parent);``)
+
+For the full documentation see :doc:`/filesystems/debugfs`.

+KASAN is a dynamic memory error detector that helps to find use-after-free and
+out-of-bounds bugs. It uses compile-time instrumentation to check every memory
+access.
+
+For the full documentation see :doc:`/dev-tools/kasan`.
+
+UBSAN (Undefined Behavior Sanitizer)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Prerequisite: ``CONFIG_UBSAN``
+
+UBSAN relies on compiler instrumentation and runtime checks to detect undefined
+behavior. It is designed to find a variety of issues, including signed integer
+overflow, array index out of bounds, and more.
+
+For the full documentation see :doc:`/dev-tools/ubsan`
+
+lockdep (Lock Dependency Validator)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Prerequisite: ``CONFIG_DEBUG_LOCKDEP``
+
+lockdep is a runtime lock dependency validator that detects potential deadlocks
+and other locking-related issues in the kernel.
+It tracks lock acquisitions and releases, building a dependency graph that is
+analyzed for potential deadlocks.
+lockdep is especially useful for validating the correctness of lock ordering in
+the kernel.
+
+PSI (Pressure stall information tracking)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Prerequisite: ``CONFIG_PSI``
+
+PSI is a measurement tool to identify excessive overcommits on hardware
+resources, that can cause performance disruptions or even OOM kills.
+
+device coredump
+---------------
+
+Prerequisite: ``#include <linux/devcoredump.h>``
+
+Provides the infrastructure for a driver to provide arbitrary data to userland.
+It is most often used in conjunction with udev or similar userland application
+to listen for kernel uevents, which indicate that the dump is ready. Udev has
+rules to copy that file somewhere for long-term storage and analysis, as by
+default, the data for the dump is automatically cleaned up after 5 minutes.
+That data is analyzed with driver-specific tools or GDB.
+
+You can find an example implementation at:
+`drivers/media/platform/qcom/venus/core.c
+<https://elixir.bootlin.com/linux/v6.11.6/source/drivers/media/platform/qcom/venus/core.c#L30>`__

+
+General debugging advice
+========================
+
+Depending on the issue, a different set of tools is available to track down the
+problem or even to realize whether there is one in the first place.
+
+As a first step you have to figure out what kind of issue you want to debug.
+Depending on the answer, your methodology and choice of tools may vary.
+
+Do I need to debug with limited access?
+---------------------------------------
+
+Do you have limited access to the machine or are you unable to stop the running
+execution?
+
+In this case your debugging capability depends on built-in debugging support of
+provided distribution kernel.
+The :doc:`/process/debugging/userspace_debugging_guide` provides a brief
+overview over a range of possible debugging tools in that situation. You can
+check the capability of your kernel, in most cases, by looking into config file
+within the /boot directory.
+
+Do I have root access to the system?
+------------------------------------
+
+Are you easily able to replace the module in question or to install a new
+kernel?
+
+In that case your range of available tools is a lot bigger, you can find the
+tools in the :doc:`/process/debugging/driver_development_debugging_guide`.
+
+Is timing a factor?
+-------------------
+
+It is important to understand if the problem you want to debug manifests itself
+consistently (i.e. given a set of inputs you always get the same, incorrect
+output), or inconsistently. If it manifests itself inconsistently, some timing
+factor might be at play. If inserting delays into the code does change the
+behavior, then quite likely timing is a factor.
+
+When timing does alter the outcome of the code execution using a simple
+printk() for debugging purposes may not work, a similar alternative is to use
+trace_printk() , which logs the debug messages to the trace file instead of the
+kernel log.

+Userspace debugging advice
+==========================
+
+This document provides a brief overview of common tools to debug the Linux
+Kernel from userspace.
+For debugging advice aimed at driver developers go :doc:`here
+</process/debugging/driver_development_debugging_guide>`.
+For general debugging advice, see :doc:`general advice document
+</process/debugging/index>`.
+
+.. contents::
+    :depth: 3
+
+The following sections show you the available tools.
+
+Dynamic debug
+-------------
+
+Mechanism to filter what ends up in the kernel log by dis-/en-abling log
+messages.
+
+Prerequisite: ``CONFIG_DYNAMIC_DEBUG``
+
+Dynamic debug is only able to target:
+
+- pr_debug()
+- dev_dbg()
+- print_hex_dump_debug()
+- print_hex_dump_bytes()
+
+Therefore the usability of this tool is, as of now, quite limited as there is
+no uniform rule for adding debug prints to the codebase, resulting in a variety
+of ways these prints are implemented.
+
+Also, note that most debug statements are implemented as a variation of
+dprintk(), which have to be activated via a parameter in respective module,
+dynamic debug is unable to do that step for you.
+
+Here is one example, that enables all available pr_debug()'s within the file::
+
+  $ alias ddcmd='echo $* > /proc/dynamic_debug/control'
+  $ ddcmd '-p; file v4l2-h264.c +p'
+  $ grep =p /proc/dynamic_debug/control
+   drivers/media/v4l2-core/v4l2-h264.c:372 [v4l2_h264]print_ref_list_b =p
+   "ref_pic_list_b%u (cur_poc %u%c) %s"
+   drivers/media/v4l2-core/v4l2-h264.c:333 [v4l2_h264]print_ref_list_p =p
+   "ref_pic_list_p (cur_poc %u%c) %s\n"
+
+**When should you use this over Ftrace ?**
+
+- When the code contains one of the valid print statements (see above) or when
+  you have added multiple pr_debug() statements during development
+- When timing is not an issue, meaning if multiple pr_debug() statements in
+  the code won't cause delays
+- When you care more about receiving specific log messages than tracing the
+  pattern of how a function is called
+
+For the full documentation see :doc:`/admin-guide/dynamic-debug-howto`
+
+Ftrace
+------
+
+Prerequisite: ``CONFIG_DYNAMIC_FTRACE``
+
+This tool uses the tracefs file system for the control files and output files.
+That file system will be mounted as a ``tracing`` directory, which can be found
+in either ``/sys/kernel/`` or ``/sys/debug/kernel/``.
+
+Some of the most important operations for debugging are:
+
+- You can perform a function trace by adding a function name to the
+  ``set_ftrace_filter`` file (which accepts any function name found within the
+  ``available_filter_functions`` file) or you can specifically disable certain
+  functions by adding their names to the ``set_ftrace_notrace`` file (more info
+  at: :ref:`trace/ftrace:dynamic ftrace`).
+- In order to find out where calls originate from you can activate the
+  ``func_stack_trace`` option under ``options/func_stack_trace``.
+- Tracing the children of a function call and showing the return values are
+  possible by adding the desired function in the ``set_graph_function`` file
+  (requires config ``FUNCTION_GRAPH_RETVAL``); more info at
+  :ref:`trace/ftrace:dynamic ftrace with the function graph tracer`.
+
+For the full Ftrace documentation see :doc:`/trace/ftrace`
+
+Or you could also trace for specific events by :ref:`using event tracing
+<trace/events:2. using event tracing>`, which can be defined as described here:
+:ref:`Creating a custom Ftrace tracepoint
+<process/debugging/driver_development_debugging_guide:ftrace>`.
+
+For the full Ftrace event tracing documentation see :doc:`/trace/events`
+
+.. _read_ftrace_log:
+
+Reading the ftrace log
+~~~~~~~~~~~~~~~~~~~~~~
+
+The ``trace`` file can be read just like any other file (``cat``, ``tail``,
+``head``, ``vim``, etc.), the size of the file is limited by the
+``buffer_size_kb`` (``echo 1000 > buffer_size_kb``). The
+:ref:`trace/ftrace:trace_pipe` will behave similarly to the ``trace`` file, but
+whenever you read from the file the content is consumed.
+
+Kernelshark
+~~~~~~~~~~~
+
+A GUI interface to visualize the traces as a graph and list view from the
+output of the `trace-cmd
+<https://git.kernel.org/pub/scm/utils/trace-cmd/trace-cmd.git/>`__ application.
+
+For the full documentation see `<https://kernelshark.org/Documentation.html>`__
+
+Perf & alternatives
+-------------------
+
+The tools mentioned above provide ways to inspect kernel code, results,
+variable values, etc. Sometimes you have to find out first where to look and
+for those cases, a box of performance tracking tools can help you to frame the
+issue.
+
+Why should you do a performance analysis?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A performance analysis is a good first step when among other reasons:
+
+- you cannot define the issue
+- you do not know where it occurs
+- the running system should not be interrupted or it is a remote system, where
+  you cannot install a new module/kernel
+
+How to do a simple analysis with linux tools?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For the start of a performance analysis, you can start with the usual tools
+like:
+
+- ``top`` / ``htop`` / ``atop`` (*get an overview of the system load, see
+  spikes on specific processes*)
+- ``mpstat -P ALL`` (*look at the load distribution among CPUs*)
+- ``iostat -x`` (*observe input and output devices utilization and performance*)
+- ``vmstat`` (*overview of memory usage on the system*)
+- ``pidstat`` (*similar to* ``vmstat`` *but per process, to dial it down to the
+  target*)
+- ``strace -tp $PID`` (*once you know the process, you can figure out how it
+  communicates with the Kernel*)
+
+These should help to narrow down the areas to look at sufficiently.
+
+Diving deeper with perf
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The **perf** tool provides a series of metrics and events to further dial down
+on issues.
+
+Prerequisite: build or install perf on your system
+
+Gather statistics data for finding all files starting with ``gcc`` in ``/usr``::
+
+  # perf stat -d find /usr -name 'gcc*' | wc -l
+
+   Performance counter stats for 'find /usr -name gcc*':
+

+
+Perfetto
+~~~~~~~~
+
+A set of tools to measure and analyze how well applications and systems perform.
+You can use it to:
+
+* identify bottlenecks
+* optimize code
+* make software run faster and more efficiently.
+
+**What is the difference between perfetto and perf?**
+
+* perf is tool as part of and specialized for the Linux Kernel and has CLI user
+  interface.
+* perfetto cross-platform performance analysis stack, has extended
+  functionality into userspace and provides a WEB user interface.
+

+
+Kernel panic analysis tools
+---------------------------
+
+  To capture the crash dump please use ``Kdump`` & ``Kexec``. Below you can find
+  some advice for analysing the data.
+
+  For the full documentation see the :doc:`/admin-guide/kdump/kdump`
+
+  In order to find the corresponding line in the code you can use `faddr2line
+  <https://elixir.bootlin.com/linux/v6.11.6/source/scripts/faddr2line>`__; note
+  that you need to enable ``CONFIG_DEBUG_INFO`` for that to work.
+
+  An alternative to using ``faddr2line`` is the use of ``objdump`` (and its
+  derivatives for the different platforms like ``aarch64-linux-gnu-objdump``).
+  Take this line as an example:
+
+  ``[  +0.000240]  rkvdec_device_run+0x50/0x138 [rockchip_vdec]``.
+
+  We can find the corresponding line of code by executing::
+
+    aarch64-linux-gnu-objdump -dS drivers/staging/media/rkvdec/rockchip-vdec.ko | grep rkvdec_device_run\>: -A 40
+    0000000000000ac8 <rkvdec_device_run>:

+     aec:	b4000654 	cbz	x20, bb4 <rkvdec_device_run+0xec>
+        ret = pm_runtime_resume_and_get(rkvdec->dev);
+     af0:	f943d2b6 	ldr	x22, [x21, #1952]
+        ret = __pm_runtime_resume(dev, RPM_GET_PUT);
+     af4:	aa0003f3 	mov	x19, x0
+     af8:	52800081 	mov	w1, #0x4                   	// #4
+     afc:	aa1603e0 	mov	x0, x22
+     b00:	94000000 	bl	0 <__pm_runtime_resume>
+        if (ret < 0) {
+     b04:	37f80340 	tbnz	w0, #31, b6c <rkvdec_device_run+0xa4>
+        dev_warn(rkvdec->dev, "Not good\n");
+     b08:	f943d2a0 	ldr	x0, [x21, #1952]
+     b0c:	90000001 	adrp	x1, 0 <rkvdec_try_ctrl-0x8>
+     b10:	91000021 	add	x1, x1, #0x0
+     b14:	94000000 	bl	0 <_dev_warn>
+        *bad = 1;
+     b18:	d2800001 	mov	x1, #0x0                   	// #0
+     ...
+
+  Meaning, in this line from the crash dump::
+
+    [  +0.000240]  rkvdec_device_run+0x50/0x138 [rockchip_vdec]
+
+  I can take the ``0x50`` as offset, which I have to add to the base address
+  of the corresponding function, which I find in this line::
+
+    0000000000000ac8 <rkvdec_device_run>:
+
+  The result of ``0xac8 + 0x50 = 0xb18``
+  And when I search for that address within the function I get the
+  following line::
+
+    *bad = 1;
+    b18:      d2800001        mov     x1, #0x0

+
+General debugging advice
+------------------------
+
+For general advice see the :doc:`general advice document
+</process/debugging/index>`.
+
+The following sections show you some of the available tools.
+
+dev_debug module parameter
+--------------------------
+
+Every video device provides a ``dev_debug`` parameter, which allows to get
+further insights into the IOCTLs in the background.::
+
+  # cat /sys/class/video4linux/video3/name
+  rkvdec
+  # echo 0xff > /sys/class/video4linux/video3/dev_debug
+  # dmesg -wH
+  [...] videodev: v4l2_open: video3: open (0)

+  bus=platform:rkvdec, version=0x00060900, capabilities=0x84204000,
+  device_caps=0x04204000
+
+For the full documentation see :ref:`driver-api/media/v4l2-dev:video device
+debugging`
+
+dev_dbg() / v4l2_dbg()
+----------------------
+
+Two debug print statements, which are specific for devices and for the v4l2
+subsystem, avoid adding these to your final submission unless they have
+long-term value for investigations.
+
+For a general overview please see the
+:ref:`process/debugging/driver_development_debugging_guide:printk() & friends`
+guide.
+
+- Difference between both?
+
+  - v4l2_dbg() utilizes v4l2_printk() under the hood, which further uses
+    printk() directly, thus it cannot be targeted by dynamic debug
+  - dev_dbg() can be targeted by dynamic debug
+  - v4l2_dbg() has a more specific prefix format for the media subsystem, while
+    dev_dbg only highlights the driver name and the location of the log
+
+Dynamic debug
+-------------
+
+A method to trim down the debug output to your needs.
+
+For general advice see the
+:ref:`process/debugging/userspace_debugging_guide:dynamic debug` guide.
+
+Here is one example, that enables all available pr_debug()'s within the file::
+
+  $ alias ddcmd='echo $* > /proc/dynamic_debug/control'
+  $ ddcmd '-p; file v4l2-h264.c +p'
+  $ grep =p /proc/dynamic_debug/control
+   drivers/media/v4l2-core/v4l2-h264.c:372 [v4l2_h264]print_ref_list_b =p

+Error checking & panic analysis
+-------------------------------
+
+Various Kernel configuration options to enhance error detection of the Linux
+Kernel with the cost of lowering performance.
+
+For general advice see the
+:ref:`process/debugging/driver_development_debugging_guide:kasan, ubsan,

+
+Driver verification with v4l2-compliance
+----------------------------------------
+
+To verify, that a driver adheres to the v4l2 API, the tool v4l2-compliance is
+used, which is part of the `v4l_utils
+<https://git.linuxtv.org/v4l-utils.git>`__, a suite of userspace tools to work
+with the media subsystem.
+
+To see the detailed media topology (and check it) use::
+
+  v4l2-compliance -M /dev/mediaX --verbose
+
+You can also run a full compliance check for all devices referenced in the
+media topology with::
+
+  v4l2-compliance -m /dev/mediaX
+
+Debugging problems with receiving video
+---------------------------------------
+
+Implementing vidioc_log_status in the driver: this can log the current status
+to the kernel log. It's called by v4l2-ctl --log-status. Very useful for
+debugging problems with receiving video (TV/S-Video/HDMI/etc) since the video
+signal is external (so unpredictable). Less useful with camera sensor inputs
+since you have control over what the camera sensor does.
+
+Usually you can just assign the default::
+
+  .vidioc_log_status  = v4l2_ctrl_log_status,
+
+But you can also create your own callback, to create a custom status log.
+
+You can find an example in the cobalt driver
+(`drivers/media/pci/cobalt/cobalt-v4l2.c <https://elixir.bootlin.com/linux/v6.11.6/source/drivers/media/pci/cobalt/cobalt-v4l2.c#L567>`__).

Subject: [PATCH 2528/2948] iommu: Add ops->domain_alloc_nested()

It turns out all the drivers that are using this immediately call into
another function, so just make that function directly into the op. This
makes paging=NULL for domain_alloc_user and we can remove the argument in
the next patch.

The function mirrors the similar op in the viommu that allocates a nested
domain on top of the viommu's nesting parent. This version supports cases
where a viommu is not being used.

Subject: [PATCH 2529/2948] iommu: Rename ops->domain_alloc_user() to
 domain_alloc_paging_flags()

Now that the main domain allocating path is calling this function it
doesn't make sense to leave it named _user. Change the name to
alloc_paging_flags() to mirror the new iommu_paging_domain_alloc_flags()
function.

A driver should implement only one of ops->domain_alloc_paging() or
ops->domain_alloc_paging_flags(). The former is a simpler interface with
less boiler plate that the majority of drivers use. The latter is for
drivers with a greater feature set (PASID, multiple page table support,
advanced iommufd support, nesting, etc). Additional patches will be needed
to achieve this.

Subject: [PATCH 2530/2948] m68k: mvme147, mvme16x: Adopt rtc-m48t59 platform
 driver

Both mvme147 and mvme16x platforms have their own RTC driver
implementations that duplicate functionality provided by the rtc-m48t59
driver. Adopt the rtc-m48t59 driver and remove the other ones.

Subject: [PATCH 2531/2948] ACPI: x86: Add skip i2c clients quirk for Acer
 Iconia One 8 A1-840

The Acer Iconia One 8 A1-840 (not to be confused with the A1-840FHD which
is a different model) ships with Android 4.4 as factory OS and has the
usual broken DSDT issues for x86 Android tablets.

Add quirks to skip ACPI I2C client enumeration and disable ACPI battery/AC
and ACPI GPIO event handlers.

Also add the "INT33F5" HID for the TI PMIC used on this tablet to the list
of HIDs for which not to skip i2c_client instantiation, since we do want
an ACPI instantiated i2c_client for the PMIC.

 acpi_quirk_skip_dmi_ids[]

The Asus entries in the acpi_quirk_skip_dmi_ids[] table are the only
entries without a comment which model they apply to. Add these comments.

The Asus TF103C entry also is in the wrong place for what is supposed to
be an alphabetically sorted list. Move it up so that the list is properly
sorted and add a comment that the list is alphabetically sorted.

Subject: [PATCH 2533/2948] ACPI: introduce acpi_arch_init()

To avoid arch-specific code in general ACPI initialization flow,
introduce a weak symbol acpi_arch_init().

Currently, arm64 and riscv can utillize this to insert their
arch-specific flow.

In the future, other architectures can also have a chance to define
their own arch-specific ACPI initialization process if necessary.

Subject: [PATCH 2536/2948] perf/test: fix perf ftrace test on s390

On s390 the perf test case ftrace sometimes fails as follows:

  # ./perf test ftrace
  79: perf ftrace tests    : FAILED!
  #

The failure depends on the kernel .config file. Some configurations
always work fine, some do not.  The ftrace profile test mostly fails,
because the ring buffer was not large enough, and some lines
(especially the interesting ones with nanosleep in it) where dropped.

To achieve success for all tested kernel configurations, enlarge
the buffer to store the traces completely without wrapping.
The default buffer size is too small for all kernel configurations.
Set the buffer size of for the ftrace profile test to 16 MB.

Output after:
  # ./perf test ftrace
  79: perf ftrace tests     : Ok
  #

Subject: [PATCH 2539/2948] perf tests: Fix hwmon parsing with PMU name test

Incorrectly the hwmon with PMU name test didn't pass "true". Fix and
address issue with hwmon_pmu__config_terms needing to load events - a
load bearing assert fired. Also fix missing list deletion when putting
the hwmon test PMU and lower some debug warnings to make the hwmon PMU
less spammy in verbose mode.

Subject: [PATCH 2541/2948] MIPS: Loongson64: DTS: Really fix PCIe port nodes
 for ls7a

Fix the dtc warnings:

    arch/mips/boot/dts/loongson/ls7a-pch.dtsi:68.16-416.5: Warning (interrupt_provider): /bus@10000000/pci@1a000000: '#interrupt-cells' found, but node is not an interrupt provider
    arch/mips/boot/dts/loongson/ls7a-pch.dtsi:68.16-416.5: Warning (interrupt_provider): /bus@10000000/pci@1a000000: '#interrupt-cells' found, but node is not an interrupt provider
    arch/mips/boot/dts/loongson/loongson64g_4core_ls7a.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider'

And a runtime warning introduced in commit 045b14ca5c36 ("of: WARN on
deprecated #address-cells/#size-cells handling"):

    WARNING: CPU: 0 PID: 1 at drivers/of/base.c:106 of_bus_n_addr_cells+0x9c/0xe0
    Missing '#address-cells' in /bus@10000000/pci@1a000000/pci_bridge@9,0

The fix is similar to commit d89a415ff8d5 ("MIPS: Loongson64: DTS: Fix PCIe
port nodes for ls7a"), which has fixed the issue for ls2k (despite its
subject mentions ls7a).

Subject: [PATCH 2542/2948] f2fs: add a sysfs node to limit max read extent
 count per-inode

Quoted:
"at this time, there are still 1086911 extent nodes in this zombie
extent tree that need to be cleaned up.

crash_arm64_sprd_v8.0.3++> extent_tree.node_cnt ffffff80896cc500
  node_cnt = {
    counter = 1086911
  },
"

As reported by Xiuhong, there will be a huge number of extent nodes
in extent tree, it may potentially cause:
- slab memory fragments
- extreme long time shrink on extent tree
- low mapping efficiency

Let's add a sysfs node to limit max read extent count for each inode,
by default, value of this threshold is 10240, it can be updated
according to user's requirement.

Subject: [PATCH 2543/2948] f2fs: fix to drop all discards after creating
 snapshot on lvm device

Piergiorgio reported a bug in bugzilla as below:

------------[ cut here ]------------
WARNING: CPU: 2 PID: 969 at fs/f2fs/segment.c:1330
RIP: 0010:__submit_discard_cmd+0x27d/0x400 [f2fs]
Call Trace:
 __issue_discard_cmd+0x1ca/0x350 [f2fs]
 issue_discard_thread+0x191/0x480 [f2fs]
 kthread+0xcf/0x100
 ret_from_fork+0x31/0x50
 ret_from_fork_asm+0x1a/0x30

w/ below testcase, it can reproduce this bug quickly:
- pvcreate /dev/vdb
- vgcreate myvg1 /dev/vdb
- lvcreate -L 1024m -n mylv1 myvg1
- mount /dev/myvg1/mylv1 /mnt/f2fs
- dd if=/dev/zero of=/mnt/f2fs/file bs=1M count=20
- sync
- rm /mnt/f2fs/file
- sync
- lvcreate -L 1024m -s -n mylv1-snapshot /dev/myvg1/mylv1
- umount /mnt/f2fs

The root cause is: it will update discard_max_bytes of mounted lvm
device to zero after creating snapshot on this lvm device, then,
__submit_discard_cmd() will pass parameter @nr_sects w/ zero value
to __blkdev_issue_discard(), it returns a NULL bio pointer, result
in panic.

This patch changes as below for fixing:
1. Let's drop all remained discards in f2fs_unfreeze() if snapshot
of lvm device is created.
2. Checking discard_max_bytes before submitting discard during
__submit_discard_cmd().

Subject: [PATCH 2549/2948] tracing: Remove conditional locking from
 __DO_TRACE()

Remove conditional locking by moving the __DO_TRACE() code into
trace_##name().

When the faultable syscall tracepoints were implemented, __DO_TRACE()
had a rcuidle argument which selected between SRCU and preempt disable.
Therefore, the RCU tasks trace protection for faultable syscall
tracepoints was introduced using the same pattern.

At that point, it did not appear obvious that this feedback from Linus [1]
applied here as well, because the __DO_TRACE() modification was
extending a pre-existing pattern.

Shortly before pulling the faultable syscall tracepoints modifications,
Steven removed the rcuidle argument and SRCU protection scheme entirely
from tracepoint.h:

commit 48bcda684823 ("tracing: Remove definition of trace_*_rcuidle()")

This required a rebase of the faultable syscall tracepoints series,
which missed a perfect opportunity to integrate the prior recommendation
from Linus.

In response to the pull request, Linus pointed out [2] that he was not
pleased by the implementation, expecting this to be fixed in a follow up
patch series.

Move __DO_TRACE() code into trace_##name() within each of
__DECLARE_TRACE() and __DECLARE_TRACE_SYSCALL(). Use a scoped guard
to guard the preempt disable notrace and RCU tasks trace critical
sections.

don't require condition evaluation.

Subject: [PATCH 2554/2948] i2c: designware: Add ACPI HID for DWAPB I2C
 controller on FUJITSU-MONAKA

Enable DWAPB I2C controller support on FUJITSU-MONAKA.
This will be used in the FUJITSU-MONAKA server scheduled
for shipment in 2027.

The DSDT information obtained when verified using an
in-house simulator is presented below.

     Device (SMB0)
     {
         Name (_HID, "FUJI200B")  // _HID: Hardware ID
         Name (_UID, Zero)  // _UID: Unique ID
         ...
         Name (_CRS, ResourceTemplate ()
         {
             Memory32Fixed (ReadWrite,
                 0x2A4B0000,         // Address Base
                 0x00010000,         // Address Length
                 )
             Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive, ,, )
             {
                 0x00000159,
             }
         })
         ...
     }

The expression SMB0 is used to indicate SMBus HC#0,
a string of up to four characters.

Created the SMB0 object according to the following
specifications:

ACPI Specification
13.2. Accessing the SMBus from ASL Code

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After EyeQ5, it is time for Mobileye EyeQ6H to reuse the Nomadik I2C
controller. Add a specific compatible because its HW integration is
slightly different from EyeQ5.

Do NOT add an example as it looks like EyeQ5 from a DT standpoint
(without the mobileye,olb property).

 to of_match_device()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Compatible-specific behavior is implemented using a if-condition on the
return value from of_device_is_compatible(), from probe. It does not
scale well when compatible number increases. Switch to using a match
table and a call to of_match_device().

We DO NOT attach a .of_match_table field to our amba driver, as we do
not use the table to match our driver to devices.

Sort probe variable declarations in reverse christmas tree to try and
introduce some logic into the ordering.

 controller
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add EyeQ6H support to the nmk-i2c AMBA driver. It shares the same quirk
as EyeQ5: the memory bus only supports 32-bit accesses. Avoid writeb()
and readb() by reusing the same `priv->has_32b_bus` flag.

It does NOT need to write speed-mode specific value into a register;
therefore it does not depend on the mobileye,olb DT property.

Subject: [PATCH 2560/2948] i2c: nomadik: fix BRCR computation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Current BRCR computation is:

    brcr = floor(i2cclk / (clkfreq * div))

With brcr: "baud rate counter", an internal clock divider,
 and i2cclk: input clock rate (24MHz, 38.4MHz or 48MHz),
 and clkfreq: desired bus rate,
 and div: speed-mode dependent divider (2 for standard, 3 otherwise).

Assume i2cclk=48MHz, clkfreq=3.4MHz, div=3,
  then brcr = floor(48MHz / (3.4MHz * 3)) = 4
   and resulting bus rate = 48MHz / (4 * 3) = 4MHz

Assume i2cclk=38.4MHz, clkfreq=1.0MHz, div=3,
  then brcr = floor(38.4MHz / (1.0MHz * 3)) = 12
   and resulting bus rate = 38.4MHz / (12 * 3) = 1066kHz

The current computation means we always pick the smallest divider that
gives a bus rate above target. We should instead pick the largest
divider that gives a bus rate below target, using:

    brcr = floor(i2cclk / (clkfreq * div)) + 1

If we redo the above examples:

Assume i2cclk=48MHz, clkfreq=3.4MHz, div=3,
  then brcr = floor(48MHz / (3.4MHz * 3)) + 1 = 5
   and resulting bus rate = 48MHz / (5 * 3) = 3.2MHz

Assume i2cclk=38.4MHz, clkfreq=1.0MHz, div=3,
  then brcr = floor(38.4MHz / (1.0MHz * 3)) + 1 = 13
   and resulting bus rate = 38.4MHz / (13 * 3) = 985kHz

In kernel C code, floor(x)   is DIV_ROUND_DOWN() and,
                  floor(x)+1 is DIV_ROUND_UP().

This is much less of an issue with slower bus rates (ie those currently
supported), because the gap from one divider to the next is much
smaller. It however keeps us from always using bus rates superior to
the target.

This fix is required for later on supporting faster bus rates:
I2C_FREQ_MODE_FAST_PLUS (1MHz) and I2C_FREQ_MODE_HIGH_SPEED (3.4MHz).

 - BRCR value must go into the BRCR1 field when in high-speed mode.
   It goes into BRCR2 otherwise.

 - Remove fallback to standard mode if priv->sm > I2C_FREQ_MODE_FAST.

 - Set SM properly in probe; previously it only checked STANDARD versus
   FAST. Now we set STANDARD, FAST, FAST_PLUS or HIGH_SPEED.

 - Remove all comment sections saying we only support low-speeds.

Subject: [PATCH 2562/2948] dt-bindings: i2c: snps,designware-i2c: declare bus
 capacitance and clk freq optimized

Since there are no registers controlling the hardware parameters
IC_CAP_LOADING and IC_CLK_FREQ_OPTIMIZATION, their values can only be
declared in the device tree.

snps,bus-capacitance-pf indicates the bus capacitance in picofarads (pF).
It affects the high and low pulse width of SCL line in high speed mode.
The legal values for this property are 100 and 400 only, and default
value is 100. This property corresponds to IC_CAP_LOADING.

snps,clk-freq-optimized indicates whether the hardware reduce its
internal clock frequency by reducing the internal latency required to
generate the high period and low period of SCL line. This property
corresponds to IC_CLK_FREQ_OPTIMIZATION.

The driver can calculate the high period count and low period count of
SCL line for high speed mode based on these two properties.

Subject: [PATCH 2563/2948] i2c: designware: determine HS tHIGH and tLOW based
 on HW parameters

In commit 35eba185fd1a ("i2c: designware: Calculate SCL timing parameter
for High Speed Mode") the SCL high period count and low period count for
high speed mode are calculated based on fixed tHIGH = 160 and tLOW = 120.
However, the set of two fixed values is only applicable to the combination
of hardware parameters IC_CAP_LOADING is 400 and IC_CLK_FREQ_OPTIMIZATION
is true. Outside of this combination, the SCL frequency may not reach
3.4 MHz because the fixed tHIGH and tLOW are not small enough.

If IC_CAP_LOADING is 400, it means the bus capacitance is 400pF;
Otherwise, 100 pF. If IC_CLK_FREQ_OPTIMIZATION is true, it means that the
hardware reduces its internal clock frequency by reducing the internal
latency required to generate the high period and low period of the SCL line.

Section 3.15.4.5 in DesignWare DW_apb_i2b Databook v2.03 says that when
IC_CLK_FREQ_OPTIMIZATION = 0,

    MIN_SCL_HIGHtime = 60 ns for 3.4 Mbps, bus loading = 100pF
		     = 120 ns for 3.4 Mbps, bus loading = 400pF
    MIN_SCL_LOWtime = 160 ns for 3.4 Mbps, bus loading = 100pF
		    = 320 ns for 3.4 Mbps, bus loading = 400pF

and section 3.15.4.6 says that when IC_CLK_FREQ_OPTIMIZATION = 1,

    MIN_SCL_HIGHtime = 60 ns for 3.4 Mbps, bus loading = 100pF
		     = 160 ns for 3.4 Mbps, bus loading = 400pF
    MIN_SCL_LOWtime = 120 ns for 3.4 Mbps, bus loading = 100pF
		    = 320 ns for 3.4 Mbps, bus loading = 400pF

In order to calculate more accurate SCL high period count and low period
count for high speed mode, two hardware parameters IC_CAP_LOADING and
IC_CLK_FREQ_OPTIMIZATION must be considered together. Since there're no
registers controlliing these these two hardware parameters, users can
declare them in the device tree so that the driver can obtain them.

Commit 120584c728a6 ("hwmon: (aquacomputer_d5next) Add support for Octo
flow sensor") added support for reading Octo flow sensor, but didn't
update the priv->speed_input array length. Since Octo has 8 fans, with
the addition of the flow sensor the proper length for speed_input is 9.

Subject: [PATCH 2568/2948] s390/mm: Allow large pages for KASAN shadow mapping

Commit c98d2ecae08f ("s390/mm: Uncouple physical vs virtual address
spaces") introduced a large_allowed() helper that restricts which mapping
modes can use large pages. This change unintentionally prevented KASAN
shadow mappings from using large pages, despite there being no reason
to avoid them. In fact, large pages are preferred for performance.

Add POPULATE_KASAN_MAP_SHADOW to the allowed list in large_allowed()
to restore large page mappings for KASAN shadows.

While large_allowed() isn't strictly necessary with current mapping
modes since disallowed modes either don't map anything or fail alignment
and size checks, keep it for clarity.

Subject: [PATCH 2569/2948] dt-bindings: mailbox: mpfs: fix reg properties

When the binding for this was originally written, and later modified,
mistakes were made - and the precise nature of the later modification
should have been a giveaway, but alas I was naive at the time.

A more correct modelling of the hardware is to use two syscons and have
a single reg entry for the mailbox, containing the mailbox region. The
two syscons contain the general control/status registers for the mailbox
and the interrupt related registers respectively. The reason for two
syscons is that the same mailbox is present on the non-SoC version of
the FPGA, which has no interrupt controller, and the shared part of the
rtl was unchanged between devices.

This is now coming to a head, because the control/status registers share
a register region with the "tvs" (temperature & voltage sensors)
registers and, as it turns out, people do want to monitor temperatures
and voltages...

Subject: [PATCH 2570/2948] mailbox: mpfs: support new, syscon based,
 devicetree configuration

The two previous bindings for this hardware were incorrect, as the
control/status and interrupt register regions should have been described
as syscons and dealt with via regmap in the driver. Add support for
accessing these registers using that method now, so that the hwmon
driver can be supported without using auxdev or hacks with io_remap().

Subject: [PATCH 2572/2948] mailbox: qcom-cpucp: Mark the irq with
 IRQF_NO_SUSPEND flag

The qcom-cpucp mailbox irq is expected to function during suspend-resume
cycle particularly when the scmi cpufreq driver can query the current
frequency using the get_level message after the cpus are brought up during
resume. Hence mark the irq with IRQF_NO_SUSPEND flag to fix the do_xfer
failures we see during resume.

Err Logs:
arm-scmi firmware:scmi: timed out in resp(caller:do_xfer+0x164/0x568)
cpufreq: cpufreq_online: ->get() failed

Subject: [PATCH 2573/2948] mailbox: ti-msgmgr: Remove use of of_match_ptr()
 helper

When OF support is disabled the of_device_id struct match table can be
conditionally compiled out, this helper allows the assignment to also be
turned into a NULL conditionally. When the of_device_id struct is not
conditionally defined based on OF then the table will be unused causing a
warning. The two options are to either set the table as _maybe_unused, or
to just remove this helper since the table will always be defined.
Do the latter here.

Subject: [PATCH 2579/2948] mailbox: Introduce support for T-head TH1520
 Mailbox driver

This driver was tested using the drm/imagination GPU driver. It was able
to successfully power on the GPU, by passing a command through mailbox
from E910 core to E902 that's responsible for powering up the GPU. The
GPU driver was able to read the BVNC version from control registers,
which confirms it was successfully powered on.

[   33.957467] powervr ffef400000.gpu: [drm] loaded firmware
powervr/rogue_36.52.104.182_v1.fw
[   33.966008] powervr ffef400000.gpu: [drm] FW version v1.0 (build
6621747 OS)
[   38.978542] powervr ffef400000.gpu: [drm] *ERROR* Firmware failed to
boot

Though the driver still fails to boot the firmware, the mailbox driver
works when used with the not-yet-upstreamed firmware AON driver. There
is ongoing work to get the BXM-4-64 supported with the drm/imagination
driver [1], though it's not completed yet.

This work is based on the driver from the vendor kernel [2].

Subject: [PATCH 2581/2948] mailbox: zynqmp: setup IPI for each valid child
 node

As per zynqmp-ipi bindings, zynqmp IPI node can have multiple child nodes.
Current IPI setup function is set only for first child node. If IPI node
has multiple child nodes in the device-tree, then IPI setup fails for
child nodes other than first child node. In such case kernel will crash.
Fix this crash by registering IPI setup function for each available child
node.

Subject: [PATCH 2582/2948] mailbox: arm_mhuv2: clean up loop in
 get_irq_chan_comb()

Both the inner and outer loops in this code use the "i" iterator.
The inner loop should really use a different iterator.

It doesn't affect things in practice because the data comes from the
device tree.  The "protocol" and "windows" variables are going to be
zero.  That means we're always going to hit the "return &chans[channel];"
statement and we're not going to want to iterate through the outer
loop again.

Still it's worth fixing this for future use cases.

Subject: [PATCH 2584/2948] mailbox: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/mailbox to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

Make a few indentions consistent while touching these struct
initializers.

Subject: [PATCH 2585/2948] mailbox: pcc: Check before sending MCTP PCC
 response ACK

Type 4 PCC channels have an option to send back a response
to the platform when they are done processing the request.
The flag to indicate whether or not to respond is inside
the message body, and thus is not available to the pcc
mailbox.

If the flag is not set, still set command completion
bit after processing message.

In order to read the flag, this patch maps the shared
buffer to virtual memory. To avoid duplication of mapping
the shared buffer is then made available to be used by
the driver that uses the mailbox.

Subject: [PATCH 2586/2948] rust: allow `clippy::needless_lifetimes`

In beta Clippy (i.e. Rust 1.83.0), the `needless_lifetimes` lint has
been extended [1] to suggest eliding `impl` lifetimes, e.g.

    error: the following explicit lifetimes could be elided: 'a

        = note: `-D clippy::needless-lifetimes` implied by `-D warnings`
        = help: to override `-D warnings` add `#[allow(clippy::needless_lifetimes)]`
    help: elide the lifetimes
        |

    647 + impl<T: ?Sized + ListItem<ID>, const ID: u64> FusedIterator for Iter<'_, T, ID> {}

A possibility would have been to clean them -- the RFC patch [2] did
this, while asking if we wanted these cleanups. There is an open issue
[3] in Clippy about being able to differentiate some of the new cases,
e.g. those that do not involve introducing `'_`. Thus it seems others
feel similarly.

Thus, for the time being, we decided to `allow` the lint.

the first bullet remained, which does not make sense anymore.

Thus remove it. In addition, fix nearby typo.

Subject: [PATCH 2589/2948] net: usb: lan78xx: Fix double free issue with
 interrupt buffer allocation

In lan78xx_probe(), the buffer `buf` was being freed twice: once
implicitly through `usb_free_urb(dev->urb_intr)` with the
`URB_FREE_BUFFER` flag and again explicitly by `kfree(buf)`. This caused
a double free issue.

To resolve this, reordered `kmalloc()` and `usb_alloc_urb()` calls to
simplify the initialization sequence and removed the redundant
`kfree(buf)`.  Now, `buf` is allocated after `usb_alloc_urb()`, ensuring
it is correctly managed by  `usb_fill_int_urb()` and freed by
`usb_free_urb()` as intended.

Subject: [PATCH 2593/2948] tg3: Set coherent DMA mask bits to 31 for BCM57766
 chipsets

The hardware on Broadcom 1G chipsets have a known limitation
where they cannot handle DMA addresses that cross over 4GB.
When such an address is encountered, the hardware sets the
address overflow error bit in the DMA status register and
triggers a reset.

However, BCM57766 hardware is setting the overflow bit and
triggering a reset in some cases when there is no actual
underlying address overflow. The hardware team analyzed the
issue and concluded that it is happening when the status
block update has an address with higher (b16 to b31) bits
as 0xffff following a previous update that had lowest bits
as 0xffff.

To work around this bug in the BCM57766 hardware, set the
coherent dma mask from the current 64b to 31b. This will
ensure that upper bits of the status block DMA address are
always at most 0x7fff, thus avoiding the improper overflow
check described above. This work around is intended for only
status block and ring memories and has no effect on TX and
RX buffers as they do not require coherent memory.

VCAP API unit tests fail randomly with errors such as

   Expected 134 + 7 == iter.offset, but

       iter.reg_bitpos == 15 (0xf)
   # vcap_api_iterator_init_test: pass:0 fail:1 skip:0 total:1

Comments in the code state that "A typegroup table ends with an all-zero
terminator". Add the missing terminators.

Some of the typegroups did have a terminator of ".offset = 0, .width = 0,
.value = 0,". Replace those terminators with "{ }" (no trailing ',') for
consistency and to excplicitly state "this is a terminator".

Subject: [PATCH 2596/2948] netlink: fix false positive warning in extack
 during dumps

Commit under fixes extended extack reporting to dumps.
It works under normal conditions, because extack errors are
usually reported during ->start() or the first ->dump(),
it's quite rare that the dump starts okay but fails later.
If the dump does fail later, however, the input skb will
already have the initiating message pulled, so checking
if bad attr falls within skb->data will fail.

Switch the check to using nlh, which is always valid.

syzbot found a way to hit that scenario by filling up
the receive queue. In this case we initiate a dump
but don't call ->dump() until there is read space for
an skb.

Subject: [PATCH 2597/2948] selftests: net: test extacks in netlink dumps

Test that extacks in dumps work. The test fills up the receive buffer
to test both the inline dump (as part of sendmsg()) and delayed one
(run during recvmsg()).

Use YNL helpers to parse the messages. We need to add the test to YNL
file to make sure the right include path are used.

Subject: [PATCH 2598/2948] exfat: fix out-of-bounds access of directory
 entries

In the case of the directory size is greater than or equal to
the cluster size, if start_clu becomes an EOF cluster(an invalid
cluster) due to file system corruption, then the directory entry
where ei->hint_femp.eidx hint is outside the directory, resulting
in an out-of-bounds access, which may cause further file system
corruption.

This commit adds a check for start_clu, if it is an invalid cluster,
the file or directory will be treated as empty.

Subject: [PATCH 2599/2948] exfat: fix uninit-value in __exfat_get_dentry_set

There is no check if stream size and start_clu are invalid.
If start_clu is EOF cluster and stream size is 4096, It will
cause uninit value access. because ei->hint_femp.eidx could
be 128(if cluster size is 4K) and wrong hint will allocate
next cluster. and this cluster will be same with the cluster
that is allocated by exfat_extend_valid_size(). The previous
patch will check invalid start_clu, but for clarity, initialize
hint_femp.eidx to zero.

required before extending ->valid_size.

Subject: [PATCH 2602/2948] exfat: rename argument name for exfat_move_file and
 exfat_rename_file

In this exfat implementation, the relationship between inode and ei
is ei=EXFAT_I(inode). However, in the arguments of exfat_move_file()
and exfat_rename_file(), argument 'inode' indicates the parent
directory, but argument 'ei' indicates the target file to be renamed.
They do not have the above relationship, which is not friendly to code
readers.

So this commit renames 'inode' to 'parent_inode', making the argument
name match its role.

Subject: [PATCH 2603/2948] exfat: add exfat_get_dentry_set_by_ei() helper

This helper gets the directory entry set of the file for the exfat
inode which has been created.

It's used to remove all the instances of the pattern it replaces
making the code cleaner, it's also a preparation for changing ->dir
to record the cluster where the directory entry set is located and
changing ->entry to record the index of the directory entry within
the cluster.

Subject: [PATCH 2604/2948] exfat: move exfat_chain_set() out of
 __exfat_resolve_path()

__exfat_resolve_path() mixes two functions. The first one is to
resolve and check if the path is valid. The second one is to output
the cluster assigned to the directory.

The second one is only needed when need to traverse the directory
entries, and calling exfat_chain_set() so early causes p_dir to be
passed as an argument multiple times, increasing the complexity of
the code.

This commit moves the call to exfat_chain_set() before traversing
directory entries.

Subject: [PATCH 2606/2948] exfat: code cleanup for exfat_readdir()

For the root directory and other directories, the clusters
allocated to them can be obtained from exfat_inode_info, and
there is no need to distinguish them.

And there is no need to initialize atime/ctime/mtime/size in
exfat_readdir(), because exfat_iterate() does not use them.

Subject: [PATCH 2607/2948] exfat: reduce FAT chain traversal

Before this commit, ->dir and ->entry of exfat_inode_info record the
first cluster of the parent directory and the directory entry index
starting from this cluster.

The directory entry set will be gotten during write-back-inode/rmdir/
unlink/rename. If the clusters of the parent directory are not
continuous, the FAT chain will be traversed from the first cluster of
the parent directory to find the cluster where ->entry is located.

After this commit, ->dir records the cluster where the first directory
entry in the directory entry set is located, and ->entry records the
directory entry index in the cluster, so that there is almost no need
to access the FAT when getting the directory entry set.

Subject: [PATCH 2608/2948] x86/cpu: Fix PPIN initialization

On systems that enumerate PPIN (protected processor inventory
number) using CPUID, but where the BIOS locked the MSR to
prevent access /proc/cpuinfo reports "intel_ppin" feature as
present on all logical CPUs except for CPU 0.

This happens because ppin_init() uses x86_match_cpu() to
determine whether PPIN is supported. When called on CPU 0
the test for locked PPIN MSR results in:

	clear_cpu_cap(c, info->feature);

This clears the X86 FEATURE bit in boot_cpu_data. When other
CPUs are brought online the x86_match_cpu() fails, and the
PPIN FEATURE bit remains set for those other CPUs.

Fix by using setup_clear_cpu_cap() instead of clear_cpu_cap()
which force clears the FEATURE bit for all CPUS.

Subject: [PATCH 2611/2948] thermal: int3400: Fix reading of current_uuid for
 active policy

When the current_uuid attribute is set to the active policy UUID,
reading back the same attribute is returning "INVALID" instead of
the active policy UUID on some platforms before Ice Lake.

In platforms before Ice Lake, firmware provides a list of supported
thermal policies. In this case, user space can select any of the
supported thermal policies via a write to attribute "current_uuid".

In commit c7ff29763989 ("thermal: int340x: Update OS policy capability
handshake")', the OS policy handshake was updated to support Ice Lake
and later platforms and it treated priv->current_uuid_index=0 as
invalid. However, priv->current_uuid_index=0 is for the active policy,
only priv->current_uuid_index=-1 is invalid.

Fix this issue by updating the priv->current_uuid_index check.

Subject: [PATCH 2614/2948] thermal: int3400: Remove unneeded data_vault
 attribute_group
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The group only contains a single entry and the conditionals around its
lifecycle make clear that this won't change.

Remove the unnecessary group.

This saves some memory and it's easier to read.

The removal of a non-const bin_attribute[] instance is also a
preparation for the constification of struct bin_attributes.

Subject: [PATCH 2617/2948] ALSA: rawmidi: Fix kvfree() call in spinlock

At the conversion of locking with guard(), I overlooked that kvfree()
must not be called inside the spinlock unlike kfree(), and this was
caught by syzkaller now.

This patch reverts the conversion partially for restoring the kvfree()
call outside the spinlock.  It's not trivial to use guard() in this
context, unfortunately.

Subject: [PATCH 2618/2948] ALSA: usb-audio: Fix out of bounds reads when
 finding clock sources
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The current USB-audio driver code doesn't check bLength of each
descriptor at traversing for clock descriptors.  That is, when a
device provides a bogus descriptor with a shorter bLength, the driver
might hit out-of-bounds reads.

For addressing it, this patch adds sanity checks to the validator
functions for the clock descriptor traversal.  When the descriptor
length is shorter than expected, it's skipped in the loop.

For the clock source and clock multiplier descriptors, we can just
check bLength against the sizeof() of each descriptor type.
OTOH, the clock selector descriptor of UAC2 and UAC3 has an array
of bNrInPins elements and two more fields at its tail, hence those
have to be checked in addition to the sizeof() check.

Subject: [PATCH 2621/2948] vfio/pci: Properly hide first-in-list PCIe extended
 capability

There are cases where a PCIe extended capability should be hidden from
the user. For example, an unknown capability (i.e., capability with ID
greater than PCI_EXT_CAP_ID_MAX) or a capability that is intentionally
chosen to be hidden from the user.

Hiding a capability is done by virtualizing and modifying the 'Next
Capability Offset' field of the previous capability so it points to the
capability after the one that should be hidden.

The special case where the first capability in the list should be hidden
is handled differently because there is no previous capability that can
be modified. In this case, the capability ID and version are zeroed
while leaving the next pointer intact. This hides the capability and
leaves an anchor for the rest of the capability list.

However, today, hiding the first capability in the list is not done
properly if the capability is unknown, as struct
vfio_pci_core_device->pci_config_map is set to the capability ID during
initialization but the capability ID is not properly checked later when
used in vfio_config_do_rw(). This leads to the following warning [1] and
to an out-of-bounds access to ecap_perms array.

Fix it by checking cap_id in vfio_config_do_rw(), and if it is greater
than PCI_EXT_CAP_ID_MAX, use an alternative struct perm_bits for direct
read only access instead of the ecap_perms array.

Note that this is safe since the above is the only case where cap_id can
exceed PCI_EXT_CAP_ID_MAX (except for the special capabilities, which
are already checked before).

Subject: [PATCH 2625/2948] PCI: rockchip-ep: Fix address translation unit
 programming
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Rockchip PCIe endpoint controller handles PCIe transfers addresses
by masking the lower bits of the programmed PCI address and using the
same number of lower bits masked from the CPU address space used for the
mapping. For a PCI mapping of <size> bytes starting from <pci_addr>,
the number of bits masked is the number of address bits changing in the
address range [pci_addr..pci_addr + size - 1].

However, rockchip_pcie_prog_ep_ob_atu() calculates num_pass_bits only
using the size of the mapping, resulting in an incorrect number of mask
bits depending on the value of the PCI address to map.

Fix this by introducing the helper function
rockchip_pcie_ep_ob_atu_num_bits() to correctly calculate the number of
mask bits to use to program the address translation unit. The number of
mask bits is calculated depending on both the PCI address and size of
the mapping, and clamped between 8 and 20 using the macros
ROCKCHIP_PCIE_AT_MIN_NUM_BITS and ROCKCHIP_PCIE_AT_MAX_NUM_BITS. As
defined in the Rockchip RK3399 TRM V1.3 Part2, Sections 17.5.5.1.1 and
17.6.8.2.1, this clamping is necessary because:

  1) The lower 8 bits of the PCI address to be mapped by the outbound
     region are ignored. So a minimum of 8 address bits are needed and
     imply that the PCI address must be aligned to 256.

  2) The outbound memory regions are 1MB in size. So while we can specify
     up to 63-bits for the PCI address (num_bits filed uses bits 0 to 5 of
     the outbound address region 0 register), we must limit the number of
     valid address bits to 20 to match the memory window maximum size (1
     << 20 = 1MB).

Subject: [PATCH 2629/2948] PCI: rockchip-ep: Implement the
 pci_epc_ops::align_addr() operation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Rockchip PCIe endpoint controller handles PCIe transfers addresses
by masking the lower bits of the programmed PCI address and using the
same number of lower bits from the CPU address space used for the
mapping. For a PCI mapping of size bytes starting from pci_addr, the
number of bits masked is the number of address bits changing in the
address range [pci_addr..pci_addr + size - 1], up to 20 bits, that is,
up to 1MB mappings.

This means that when preparing a PCI address mapping, an endpoint
function driver must use an offset into the allocated controller
memory region that is equal to the mask of the starting PCI address
over rockchip_pcie_ep_ob_atu_num_bits() bits. This offset also
determines the maximum size of the mapping given the starting PCI
address and the fixed 1MB controller memory window size.

Implement the ->align_addr() endpoint controller operation to allow the
mapping alignment to be transparently handled by endpoint function
drivers through the function pci_epc_mem_map().

Subject: [PATCH 2630/2948] PCI: rockchip-ep: Fix MSI IRQ data mapping
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The call to rockchip_pcie_prog_ep_ob_atu() used to map the PCI address
of MSI data to the memory window allocated on probe for IRQs is done
in rockchip_pcie_ep_send_msi_irq() assuming a fixed alignment to a
256B boundary of the PCI address.  This is not correct as the alignment
constraint for the RK3399 PCI mapping depends on the number of bits of
address changing in the mapped region. This leads to an unstable system
which sometimes work and sometimes does not (crashing on paging faults
when memcpy_toio() or memcpy_fromio() are used).

Similar to regular data mapping, the MSI data mapping must thus be
handled according to the information provided by
rockchip_pcie_ep_align_addr(). Modify rockchip_pcie_ep_send_msi_irq()
to use rockchip_pcie_ep_align_addr() to correctly program entry 0 of
the ATU for sending MSI IRQs.

Subject: [PATCH 2634/2948] PCI: rockchip-ep: Refactor endpoint link training
 enable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The function rockchip_pcie_init_port() enables link training for a
controller configured in EP mode. Enabling link training is again done
in rockchip_pcie_ep_probe() after that function executed
rockchip_pcie_init_port(). Enabling link training only needs to be done
once, and doing so at the probe stage before the controller is actually
started by the user serves no purpose.

Refactor this by removing the link training enablement from both
rockchip_pcie_init_port() and rockchip_pcie_ep_probe() and moving it to
the endpoint start operation defined with rockchip_pcie_ep_start().
Enabling the controller configuration using the PCIE_CLIENT_CONF_ENABLE
bit in the same PCIE_CLIENT_CONFIG register is also moved to
rockchip_pcie_ep_start() and both the controller configuration and link
training enable bits are set with a single call to
rockchip_pcie_write().

Define the EPC operation ->stop() for the Rockchip endpoint driver with
the function rockchip_pcie_ep_stop(). This function disables link
training and the controller configuration, as the reverse to what
the start operation defined with rockchip_pcie_ep_start() does.

Subject: [PATCH 2636/2948] PCI: rockchip-ep: Improve link training
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Rockchip RK3399 TRM V1.3 Part2, Section 17.5.8.1.2, step 7,
describes the endpoint mode link training process clearly and states
that:

  Insure link training completion and success by observing link_st field
  in PCIe Client BASIC_STATUS1 register change to 2'b11. If both side
  support PCIe Gen2 speed, re-train can be Initiated by asserting the
  Retrain Link field in Link Control and Status Register. The software
  should insure the BASIC_STATUS0[negotiated_speed] changes to "1", that
  indicates re-train to Gen2 successfully.

This procedure is very similar to what is done for the root-port mode
in rockchip_pcie_host_init_port().

Implement this link training procedure for the endpoint mode as well.
Given that the RK3399 SoC does not have an interrupt signaling link
status changes, training is implemented as a delayed work which is
rescheduled until the link training completes or the endpoint controller
is stopped. The link training work is first scheduled in
rockchip_pcie_ep_start() when the endpoint function is started. Link
training completion is signaled to the function using pci_epc_linkup().
Accordingly, the linkup_notifier field of the Rockchip pci_epc_features
structure is changed to true.

Subject: [PATCH 2637/2948] PCI: rockchip-ep: Handle PERST# signal in EP mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, the Rockchip PCIe endpoint controller driver does not handle
the PERST# signal, which prevents detecting when link training should
actually be started or if the host resets the device. This however can
be supported using the controller reset_gpios property set as an input
GPIO for endpoint mode.

Modify the Rockchip PCI endpoint controller driver to get the reset_gpio
and its associated interrupt which is serviced using a threaded IRQ with
the function rockchip_pcie_ep_perst_irq_thread() as handler.

This handler function notifies a link down event corresponding to the RC
side asserting the PERST# signal using pci_epc_linkdown() when the gpio
is high. Once the gpio value goes down, corresponding to the RC
de-asserting the PERST# signal, link training is started. The polarity
of the gpio interrupt trigger is changed from high to low after the RC
asserted PERST#, and conversely changed from low to high after the RC
de-asserts PERST#.

Also, given that the host mode controller and the endpoint mode
controller use two different property names for the same PERST# signal
(ep_gpios property and reset_gpios property respectively), for clarity,
rename the ep_gpio field of struct rockchip_pcie to perst_gpio.

Subject: [PATCH 2639/2948] smb: client: disable directory caching when
 dir_cache_timeout is zero

Setting dir_cache_timeout to zero should disable the caching of
directory contents. Currently, even when dir_cache_timeout is zero,
some caching related functions are still invoked, which is unintended
behavior.

Fix the issue by setting tcon->nohandlecache to true when
dir_cache_timeout is zero, ensuring that directory handle caching
is properly disabled.

Subject: [PATCH 2642/2948] futex: improve user space accesses

Josh Poimboeuf reports that he got a "will-it-scale.per_process_ops 1.9%
improvement" report for his patch that changed __get_user() to use
pointer masking instead of the explicit speculation barrier.  However,
that patch doesn't actually work in the general case, because some (very
bad) architecture-specific code actually depends on __get_user() also
working on kernel addresses.

A profile showed that the offending __get_user() was the futex code,
which really should be fixed up to not use that horrid legacy case.
Rewrite futex_get_value_locked() to use the modern user acccess helpers,
and inline it so that the compiler not only avoids the function call for
a few instructions, but can do CSE on the address masking.

It also turns out the x86 futex functions have unnecessary barriers in
other places, so let's fix those up too.

Subject: [PATCH 2643/2948] x86: fix off-by-one in access_ok()

When the size isn't a small constant, __access_ok() will call
valid_user_address() with the address after the last byte of the user
buffer.

It is valid for a buffer to end with the last valid user address so
valid_user_address() must allow accesses to the base of the guard page.

[ This introduces an off-by-one in the other direction for the plain
  non-sized accesses, but since we have that guard region that is a
  whole page, those checks "allowing" accesses to that guard region
  don't really matter. The access will fault anyway, whether to the
  guard page or if the address has been masked to all ones - Linus ]

Subject: [PATCH 2644/2948] x86/Documentation: Update algo in init_size
 description of boot protocol

The init_size description of boot protocol has an example of the runtime
start address for the compressed bzImage. For non-relocatable kernel
it relies on the pref_address value (if not 0), but for relocatable case
only pays respect to the load_addres and kernel_alignment, and it is
inaccurate for the latter. Boot loader must consider the pref_address
as the Linux kernel relocates to it before being decompressed as nicely
described in this commit message a year ago:

  43b1d3e68ee7 ("kexec: Allocate kernel above bzImage's pref_address")

Due to this documentation inaccuracy some of the bootloaders (*) made a
mistake in the calculations and if kernel image is big enough, this may
lead to unbootable configurations.

*)
  In particular, kexec-tools missed that and resently got a couple of
  changes which will be part of v2.0.30 release. For the record,
  commit 43b1d3e68ee7 only fixed the kernel kexec implementation and
  also missed to update the init_size description.

While at it, make an example C-like looking as it's done elsewhere in
the document and fix indentation as presribed by the reStructuredText
specifications, so the syntax highliting will work properly.

Fixes: 43b1d3e68ee7 ("kexec: Allocate kernel above bzImage's pref_address")
Fixes: d297366ba692 ("x86: document new bzImage fields")

Subject: [PATCH 2645/2948] smb: client: fix NULL ptr deref in
 crypto_aead_setkey()

Neither SMB3.0 or SMB3.02 supports encryption negotiate context, so
when SMB2_GLOBAL_CAP_ENCRYPTION flag is set in the negotiate response,
the client uses AES-128-CCM as the default cipher.  See MS-SMB2
3.3.5.4.

Commit b0abcd65ec54 ("smb: client: fix UAF in async decryption") added
a @server->cipher_type check to conditionally call
smb3_crypto_aead_allocate(), but that check would always be false as
@server->cipher_type is unset for SMB3.02.

Fix the following KASAN splat by setting @server->cipher_type for
SMB3.02 as well.

Subject: [PATCH 2646/2948] cifs: Fix parsing native symlinks relative to the
 export
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SMB symlink which has SYMLINK_FLAG_RELATIVE set is relative (as opposite of
the absolute) and it can be relative either to the current directory (where
is the symlink stored) or relative to the top level export path. To what it
is relative depends on the first character of the symlink target path.

If the first character is path separator then symlink is relative to the
export, otherwise to the current directory. Linux (and generally POSIX
systems) supports only symlink paths relative to the current directory
where is symlink stored.

Currently if Linux SMB client reads relative SMB symlink with first
character as path separator (slash), it let as is. Which means that Linux
interpret it as absolute symlink pointing from the root (/). But this
location is different than the top level directory of SMB export (unless
SMB export was mounted to the root) and thefore SMB symlinks relative to
the export are interpreted wrongly by Linux SMB client.

Fix this problem. As Linux does not have equivalent of the path relative to
the top of the mount point, convert such symlink target path relative to
the current directory. Do this by prepending "../" pattern N times before
the SMB target path, where N is the number of path separators found in SMB
symlink path.

So for example, if SMB share is mounted to Linux path /mnt/share/, symlink
is stored in file /mnt/share/test/folder1/symlink (so SMB symlink path is
test\folder1\symlink) and SMB symlink target points to \test\folder2\file,
then convert symlink target path to Linux path ../../test/folder2/file.

Deduplicate code for parsing SMB symlinks in native form from functions
smb2_parse_symlink_response() and parse_reparse_native_symlink() into new
function smb2_parse_native_symlink() and pass into this new function a new
full_path parameter from callers, which specify SMB full path where is
symlink stored.

This change fixes resolving of the native Windows symlinks relative to the
top level directory of the SMB share.

Check that path buffer has correct length (it is non-zero and in UNICODE

null character (UTF-16 null codepoint in UNICODE mode or null byte in
non-unicode mode) because Linux cannot process symlink with null byte.

Subject: [PATCH 2648/2948] cifs: Add support for parsing WSL-style symlinks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Linux CIFS client currently does not implement readlink() for WSL-style
symlinks. It is only able to detect that file is of WSL-style symlink, but
is not able to read target symlink location.

Add this missing functionality and implement support for parsing content of
WSL-style symlink.

The important note is that symlink target location stored for WSL symlink
reparse point (IO_REPARSE_TAG_LX_SYMLINK) is in UTF-8 encoding instead of
UTF-16 (which is used in whole SMB protocol and also in all other symlink
styles). So for proper locale/cp support it is needed to do conversion from
UTF-8 to local_nls.

$LXDEV xattr is for storing block/char device's major and minor number.
Change guard which excludes storing $LXDEV xattr to explicitly filter
everything except block and char device. Current guard is opposite, which
is currently correct but is less-safe. This change is required for adding
support for creating WSL-style symlinks as symlinks also do not use
device's major and minor numbers.

 in SMB1 non-UNICODE session
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SMB1 NT_TRANSACT_IOCTL/FSCTL_GET_REPARSE_POINT even in non-UNICODE mode
returns reparse buffer in UNICODE/UTF-16 format.

This is because FSCTL_GET_REPARSE_POINT is NT-based IOCTL which does not
distinguish between 8-bit non-UNICODE and 16-bit UNICODE modes and its path
buffers are always encoded in UTF-16.

This change fixes reading of native symlinks in SMB1 when UNICODE session
is not active.

Subject: [PATCH 2654/2948] rtc: ab-eoz9: don't fail temperature reads on
 undervoltage notification

The undervoltage flags reported by the RTC are useful to know if the
time and date are reliable after a reboot. Although the threshold VLOW1
indicates that the thermometer has been shutdown and time compensation
is off, it doesn't mean that the temperature readout is currently
impossible.

As the system is running, the RTC voltage is now fully established and
we can read the temperature.

Subject: [PATCH 2655/2948] ksmbd: use __GFP_RETRY_MAYFAIL

Prefer to report ENOMEM rather than incur the oom for allocations in
ksmbd. __GFP_NORETRY could not achieve that, It would fail the allocations
just too easily. __GFP_RETRY_MAYFAIL will keep retrying the allocation
until there is no more progress and fail the allocation instead go OOM
and let the caller to deal with it.

We need to know how many pending requests are left at the end of server
shutdown. That means we need to know how long the server will wait
to process pending requests in case of a server shutdown.

Subject: [PATCH 2661/2948] ksmbd: fix use-after-free in SMB request handling

A race condition exists between SMB request handling in
`ksmbd_conn_handler_loop()` and the freeing of `ksmbd_conn` in the
workqueue handler `handle_ksmbd_work()`. This leads to a UAF.
- KASAN: slab-use-after-free Read in handle_ksmbd_work
- KASAN: slab-use-after-free in rtlock_slowlock_locked

This race condition arises as follows:
- `ksmbd_conn_handler_loop()` waits for `conn->r_count` to reach zero:
  `wait_event(conn->r_count_q, atomic_read(&conn->r_count) == 0);`
- Meanwhile, `handle_ksmbd_work()` decrements `conn->r_count` using
  `atomic_dec_return(&conn->r_count)`, and if it reaches zero, calls
  `ksmbd_conn_free()`, which frees `conn`.
- However, after `handle_ksmbd_work()` decrements `conn->r_count`,
  it may still access `conn->r_count_q` in the following line:
  `waitqueue_active(&conn->r_count_q)` or `wake_up(&conn->r_count_q)`
  This results in a UAF, as `conn` has already been freed.

The discovery of this UAF can be referenced in the following PR for
syzkaller's support for SMB requests.

The merge commit ae3325f752ef ("Merge branches 'arm/smmu', 'mediatek',

declaration of 'iommu_present()' even though the 'core' branch that was
merged had removed the function (and the declaration).

Remove it for real.

Subject: [PATCH 2667/2948] ALSA: hda/tas2781: Add speaker id check for ASUS
 projects

Add speaker id check by gpio in ACPI for ASUS projects.
In other vendors, speaker id was checked by BIOS, and was applied in
last bit of subsys id, so we can load corresponding firmware binary file
for its speaker by subsys id.
But in ASUS project, the firmware binary name will be appended an extra
number to tell the speakers from different vendors. And this single digit
come from gpio level of speaker id in BIOS.

Subject: [PATCH 2669/2948] net/l2tp: fix warning in l2tp_exit_net found by
 syzbot

In l2tp's net exit handler, we check that an IDR is empty before
destroying it:

	WARN_ON_ONCE(!idr_is_empty(&pn->l2tp_tunnel_idr));
	idr_destroy(&pn->l2tp_tunnel_idr);

By forcing memory allocation failures in idr_alloc_32, syzbot is able
to provoke a condition where idr_is_empty returns false despite there
being no items in the IDR. This turns out to be because the radix tree
of the IDR contains only internal radix-tree nodes and it is this that
causes idr_is_empty to return false. The internal nodes are cleaned by
idr_destroy.

Use idr_for_each to check that the IDR is empty instead of
idr_is_empty to avoid the problem.

Subject: [PATCH 2670/2948] s390/iucv: MSG_PEEK causes memory leak in
 iucv_sock_destruct()

Passing MSG_PEEK flag to skb_recv_datagram() increments skb refcount
(skb->users) and iucv_sock_recvmsg() does not decrement skb refcount
at exit.
This results in skb memory leak in skb_queue_purge() and WARN_ON in
iucv_sock_destruct() during socket close. To fix this decrease
skb refcount by one if MSG_PEEK is set in order to prevent memory
leak and WARN_ON.

Previously, the reported speed was uniformly set to SPEED_5000, but the
RTL907XD-V1 actually operates at a speed of SPEED_10000. Therefore, this
patch makes the necessary correction.

Subject: [PATCH 2675/2948] net/ipv6: delete temporary address if mngtmpaddr is
 removed or unmanaged
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

RFC8981 section 3.4 says that existing temporary addresses must have their
lifetimes adjusted so that no temporary addresses should ever remain "valid"
or "preferred" longer than the incoming SLAAC Prefix Information. This would
strongly imply in Linux's case that if the "mngtmpaddr" address is deleted or
un-flagged as such, its corresponding temporary addresses must be cleared out
right away.

But now the temporary address is renewed even after ‘mngtmpaddr’ is removed
or becomes unmanaged as manage_tempaddrs() set temporary addresses
prefered/valid time to 0, and later in addrconf_verify_rtnl() all checkings
failed to remove the addresses. Fix this by deleting the temporary address
directly for these situations.

Subject: [PATCH 2680/2948] LoongArch: Fix build failure with GCC 15
 (-std=gnu23)

Whenever I try to build the kernel with upcoming GCC 15 which defaults
to -std=gnu23 I get a build failure:

The kernel builds explicitly with -std=gnu11 in top Makefile, but
arch/loongarch/vdso does not use KBUILD_CFLAGS from the rest of the
kernel, just add -std=gnu11 flag to arch/loongarch/vdso/Makefile.

By the way, commit e8c07082a810 ("Kbuild: move to -std=gnu11") did a
similar change for arch/arm64/kernel/vdso32/Makefile.

Subject: [PATCH 2681/2948] LoongArch: BPF: Sign-extend return values

(1) Description of Problem:

When testing BPF JIT with the latest compiler toolchains on LoongArch,
there exist some strange failed test cases, dmesg shows something like
this:

  # dmesg -t | grep FAIL | head -1
  ... ret -3 != -3 (0xfffffffd != 0xfffffffd)FAIL ...

(2) Steps to Reproduce:

  # echo 1 > /proc/sys/net/core/bpf_jit_enable
  # modprobe test_bpf

(3) Additional Info:

There are no failed test cases compiled with the lower version of GCC
such as 13.3.0, while the problems only appear with higher version of
GCC such as 14.2.0.

This is because the problems were hidden by the lower version of GCC due
to redundant sign extension instructions generated by compiler, but with
optimization of higher version of GCC, the sign extension instructions
have been removed.

(4) Root Cause Analysis:

The LoongArch architecture does not expose sub-registers, and hold all
32-bit values in a sign-extended format. While BPF, on the other hand,
exposes sub-registers, and use zero-extension (similar to arm64/x86).

This has led to some subtle bugs, where a BPF JITted program has not
sign-extended the a0 register (return value in LoongArch land), passed
the return value up the kernel, for example:

  | int from_bpf(void);
  |
  | long foo(void)
  | {
  |    return from_bpf();
  | }

Here, a0 would be 0xffffffff instead of the expected 0xffffffffffffffff.

Internally, the LoongArch JIT uses a5 as a dedicated register for BPF
return values. That is to say, the LoongArch BPF uses a5 for BPF return
values, which are zero-extended, whereas the LoongArch ABI uses a0 which
is sign-extended.

(5) Final Solution:

Keep a5 zero-extended, but explicitly sign-extend a0 (which is used
outside BPF land). Because libbpf currently defines the return value
of an ebpf program as a 32-bit unsigned integer, just use addi.w to
extend bit 31 into bits 63 through 32 of a5 to a0. This is similar to
commit 2f1b0d3d7331 ("riscv, bpf: Sign-extend return values").

Subject: [PATCH 2682/2948] LoongArch: Reduce min_delta for the arch clockevent
 device

Now the min_delta is 0x600 (1536) for LoongArch's constant clockevent
device. For a 100MHz hardware timer this means ~15us. This is a little
big, especially for PREEMPT_RT enabled kernels. So reduce it to 100 for
PREEMPT_RT kernel, and 1000 for others (we don't want too small values
to affect performance).

This is because in PREEMPT_RT kernels normal spinlocks are replaced by
rt spinlocks and rt_spin_lock() will cause sleeping. Fix it by disabling
NUMA optimization completely for PREEMPT_RT kernels.

Subject: [PATCH 2685/2948] LoongArch: Allow to enable PREEMPT_RT

It is really time.

LoongArch has all the required architecture related changes, that have
been identified over time, in order to enable PREEMPT_RT. With the recent
printk changes, the last known road block has been addressed.

Allow to enable PREEMPT_RT on LoongArch.

Below are the latency data from cyclictest on a 4-core Loongson-3A5000
machine, with a "make -j8" kernel building workload in the background.

Main instruments of tuned configuration include: Disable the boot rom
space in BIOS, in order to avoid kernel's speculative access to low-
speed memory (i.e. boot rom space); Disable CPUFreq scaling; Disable
RTC synchronization in the ntpd/chronyd service (also avoid other RTC
accesses when running low-latency workloads).

Subject: [PATCH 2686/2948] LoongArch: Allow to enable PREEMPT_LAZY

LoongArch has supported PREEMPT_RT now. It uses GENERIC_ENTRY, so just
add the TIF bit (TIF_NEED_RESCHED_LAZY) related definitions and select
the Kconfig symbol (ARCH_HAS_PREEMPT_LAZY) is enough to make it go.

Subject: [PATCH 2690/2948] marvell: pxa168_eth: fix call balance of pep->clk
 handling routines

If the clock pep->clk was not enabled in pxa168_eth_probe,
it should not be disabled in any path.

Conversely, if it was enabled in pxa168_eth_probe, it must be disabled
in all error paths to ensure proper cleanup.

Use the devm_clk_get_enabled helper function to ensure proper call balance
for pep->clk.

Found by Linux Verification Center (linuxtesting.org) with Klever.

Subject: [PATCH 2691/2948] net: stmmac: dwmac-socfpga: Set RX watchdog
 interrupt as broken

On DWMAC3 and later, there's a RX Watchdog interrupt that's used for
interrupt coalescing. It's known to be buggy on some platforms, and
dwmac-socfpga appears to be one of them. Changing the interrupt
coalescing from ethtool doesn't appear to have any effect here.

Without disabling RIWT (Received Interrupt Watchdog Timer, I
believe...), we observe latencies while receiving traffic that amount to
around ~0.4ms. This was discovered with NTP but can be easily reproduced
with a simple ping. Without this patch :

With this patch :

Subject: [PATCH 2693/2948] octeontx2-af: RPM: Fix low network performance

Low network performance is observed even on RPMs with larger
FIFO lengths.

The cn10kb silicon has three RPM blocks with the following
FIFO sizes:

         --------------------
         | RPM0  |   256KB  |
         | RPM1  |   256KB  |
         | RPM2  |   128KB  |
         --------------------

The current design stores the FIFO length in a common structure for all
RPMs (mac_ops). As a result, the FIFO length of the last RPM is applied
to all RPMs, leading to reduced network performance.

This patch resolved the problem by storing the fifo length in per MAC
structure (cgx).

Subject: [PATCH 2696/2948] octeontx2-af: Quiesce traffic before NIX block
 reset

During initialization, the AF driver resets all blocks. The RPM (MAC)
block and NIX block operate on a credit-based model. When the NIX block
resets during active traffic flow, it doesn't release credits to the RPM
block. This causes the RPM FIFO to overflow, leading to receive traffic
struck.

To address this issue, the patch introduces the following changes:
1. Stop receiving traffic at the MAC level during AF driver
   initialization.
2. Perform an X2P reset (prevents RXFIFO of all LMACS from pushing data)
3. Reset the NIX block.
4. Clear the X2P reset and re-enable receiving traffic.

Fixes: 54d557815e15 ("octeontx2-af: Reset all RVU blocks")

`atmel_qspi_reg_name()` is used for pretty-printing register offsets
for verbose logging of register accesses. However, due to a typo
(likely a copy-paste error), QSPI_RD's offset prints as "MR", the
name of the previous register. Fix this typo.

Subject: [PATCH 2699/2948] net: hsr: fix hsr_init_sk() vs network/transport
 headers.

Following sequence in hsr_init_sk() is invalid :

    skb_reset_mac_header(skb);
    skb_reset_mac_len(skb);
    skb_reset_network_header(skb);
    skb_reset_transport_header(skb);

It is invalid because skb_reset_mac_len() needs the correct
network header, which should be after the mac header.

This patch moves the skb_reset_network_header()
and skb_reset_transport_header() before
the call to dev_hard_header().

Subject: [PATCH 2700/2948] thermal: gov_power_allocator: Add missing NULL
 pointer check

Commit 0dc23567c206 ("thermal: core: Move lists of thermal instances
to trip descriptors") overlooked the case in which the Power Allocator
governor attempts to bind to a tripless thermal zone and params->trip_max
is NULL in check_power_actors().

No power actors can be found in that case, so check_power_actors() needs
to be made return 0 then to restore its previous behavior.

Fixes: 0dc23567c206 ("thermal: core: Move lists of thermal instances to trip descriptors")

Subject: [PATCH 2702/2948] thermal: of: Use scoped memory and OF handling to
 simplify thermal_of_trips_init()

Obtain the device node reference and allocate memory with
scoped/cleanup.h to reduce error handling and make the code a bit
simpler.

The code is not equivalent in one minor aspect: outgoing parameter
"*ntrips" will not be zeroed on errors of memory allocation.  This
difference is not important, because code was already not zeroing it in
case of earlier errors and the only caller does not rely on ntrips being
0 in case of errors.

Subject: [PATCH 2709/2948] bnxt_en: Reserve rings after PCIe AER recovery if
 NIC interface is down

After successful PCIe AER recovery, FW will reset all resource
reservations.  If it is IF_UP, the driver will call bnxt_open() and
all resources will be reserved again.  It it is IF_DOWN, we should
call bnxt_reserve_rings() so that we can reserve resources including
RoCE resources to allow RoCE to resume after AER.  Without this
patch, RoCE fails to resume in this IF_DOWN scenario.

Later, if it becomes IF_UP, bnxt_open() will see that resources have
been reserved and will not reserve again.

Fixes: fb1e6e562b37 ("bnxt_en: Fix AER recovery.")

 ethtool

Use the return value from bnxt_get_media() to determine the port and

the PHY is backplane.  This will correct the ethtool settings for

HWRM_RING_FREE followed by a HWRM_RING_ALLOC is not guaranteed to
have the same FW ring ID as before.  So we must reinitialize the
RSS table with the correct ring IDs.  Otherwise, traffic may not
resume properly if the restarted ring ID is stale.  Since this
feature is only supported on P5_PLUS chips, we call
bnxt_vnic_set_rss_p5() to update the HW RSS table.

Subject: [PATCH 2712/2948] bnxt_en: Fix receive ring space parameters when XDP
 is active

The MTU setting at the time an XDP multi-buffer is attached
determines whether the aggregation ring will be used and the
rx_skb_func handler.  This is done in bnxt_set_rx_skb_mode().

If the MTU is later changed, the aggregation ring setting may need
to be changed and it may become out-of-sync with the settings
initially done in bnxt_set_rx_skb_mode().  This may result in
random memory corruption and crashes as the HW may DMA data larger
than the allocated buffer size, such as:

Instead of passing the 2nd parameter phc_cfg to bnxt_ptp_init().
Store it in bp->ptp_cfg so that the caller doesn't need to know what
the value should be.

In the next patch, we'll need to call bnxt_ptp_init() in bnxt_resume()
and this will make it easier.

Subject: [PATCH 2714/2948] bnxt_en: Unregister PTP during PCI shutdown and
 suspend

If we go through the PCI shutdown or suspend path, we shutdown the
NIC but PTP remains registered.  If the kernel continues to run for
a little bit, the periodic PTP .do_aux_work() function may be called
and it will read the PHC from the BAR register.  Since the device
has already been disabled, it will cause a PCIe completion timeout.
Fix it by calling bnxt_ptp_clear() in the PCI shutdown/suspend
handlers.  bnxt_ptp_clear() will unregister from PTP and
.do_aux_work() will be canceled.

In bnxt_resume(), we need to re-initialize PTP.

Subject: [PATCH 2715/2948] ALSA: hda: Show the codec quirk info at probing

Lots of HD-audio devices need the device-specific quirk, and it's
often helpful to know which quirk is applied.  But currently the
driver shows it only as a debug output, hence we'd have to enable the
debug option at each time we want to see it (and the output becomes
too messy due to other debug messages).

This patch changes the messages to the info level, so that they appear
at probing normally.

Subject: [PATCH 2716/2948] block: Prevent potential deadlock in
 blk_revalidate_disk_zones()

The function blk_revalidate_disk_zones() calls the function
disk_update_zone_resources() after freezing the device queue. In turn,
disk_update_zone_resources() calls queue_limits_start_update() which
takes a queue limits mutex lock, resulting in the ordering:
q->q_usage_counter check -> q->limits_lock. However, the usual ordering
is to always take a queue limit lock before freezing the queue to commit
the limits updates, e.g., the code pattern:

lim = queue_limits_start_update(q);
...
blk_mq_freeze_queue(q);
ret = queue_limits_commit_update(q, &lim);
blk_mq_unfreeze_queue(q);

Thus, blk_revalidate_disk_zones() introduces a potential circular
locking dependency deadlock that lockdep sometimes catches with the
splat:

Prevent this issue by moving the calls to blk_mq_freeze_queue() and
blk_mq_unfreeze_queue() around the call to queue_limits_commit_update()
in disk_update_zone_resources(). In case of revalidation failure, the
call to disk_free_zone_resources() in blk_revalidate_disk_zones()
is still done with the queue frozen as before.

Subject: [PATCH 2717/2948] mq-deadline: don't call req_get_ioprio from the I/O
 completion handler

req_get_ioprio looks at req->bio to find the I/O priority, which is not
set when completing bios that the driver fully iterated through.

Stash away the dd_per_prio in the elevator private data instead of looking
it up again to optimize the code a bit while fixing the regression from
removing the per-request ioprio value.

Subject: [PATCH 2721/2948] Bluetooth: SCO: remove the redundant sco_conn_put

When adding conn, it is necessary to increase and retain the conn reference
count at the same time.

Another problem was fixed along the way, conn_put is missing when hcon is NULL
in the timeout routine.

Subject: [PATCH 2723/2948] irqchip/irq-mvebu-sei: Move misplaced select()
 callback to SEI CP domain

Commit fbdf14e90ce4 ("irqchip/irq-mvebu-sei: Switch to MSI parent")
introduced in v6.11-rc1 broke Mavell Armada platforms (and possibly others)
by incorrectly switching irq-mvebu-sei to MSI parent.

In the above commit, msi_parent_ops is set for the sei->cp_domain, but
rather than adding a .select method to mvebu_sei_cp_domain_ops (which is
associated with sei->cp_domain), it was added to mvebu_sei_domain_ops which
is associated with sei->sei_domain, which doesn't have any
msi_parent_ops. This makes the call to msi_lib_irq_domain_select() always
fail.

This bug manifests itself with the following kernel messages on Armada 8040
based systems:

 platform f21e0000.interrupt-controller:interrupt-controller@50: deferred probe pending: (reason unknown)
 platform f41e0000.interrupt-controller:interrupt-controller@50: deferred probe pending: (reason unknown)

Move the select callback to mvebu_sei_cp_domain_ops to cure it.

Subject: [PATCH 2724/2948] irqchip/gicv3-its: Add workaround for hip09 ITS
 erratum 162100801

When enabling GICv4.1 in hip09, VMAPP fails to clear some caches during
the unmap operation, which can causes vSGIs to be lost.

To fix the issue, invalidate the related vPE cache through GICR_INVALLR
after VMOVP.

Subject: [PATCH 2725/2948] irqchip: Switch back to struct
 platform_driver::remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return
void") .remove() is (again) the right callback to implement for platform
drivers.

Convert all platform drivers below drivers/irqchip/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done by
just changing the structure member name in the driver initializer.

Subject: [PATCH 2727/2948] io_uring: fix task_work cap overshooting

A previous commit fixed task_work overrunning by a lot more than what
the user asked for, by adding a retry list. However, it didn't cap the
overall count, hence for multiple task_work runs inside the same wait
loop, it'd still overshoot the target by potentially a large amount.

Cap it generally inside the wait path. Note that this will still
overshoot the default limit of 20, but should overshoot by no more than
limit-1 in addition to the limit. That still provides a ceiling over how
much task_work will be run, rather than still having gaps where it was
uncapped essentially.

Fixes: f46b9cdb22f7 ("io_uring: limit local tw done")

  sync_filesystem()
    ext4_sync_fs()
      dquot_writeback_dquots()

Since we currently don't always flush the quota_release_work queue in
this path, we can end up with the following race:

 1. dquot are added to releasing_dquots list during regular operations.
 2. FS Freeze starts, however, this does not flush the quota_release_work queue.
 3. Freeze completes.
 4. Kernel eventually tries to flush the workqueue while FS is frozen which
    hits a WARN_ON since transaction gets started during frozen state:

  ext4_journal_check_start+0x28/0x110 [ext4] (unreliable)
  __ext4_journal_start_sb+0x64/0x1c0 [ext4]
  ext4_release_dquot+0x90/0x1d0 [ext4]
  quota_release_workfn+0x43c/0x4d0

Which is the following line:

  WARN_ON(sb->s_writers.frozen == SB_FREEZE_COMPLETE);

Which ultimately results in generic/390 failing due to dmesg
noise. This was detected on powerpc machine 15 cores.

To avoid this, make sure to flush the workqueue during
dquot_writeback_dquots() so we dont have any pending workitems after
freeze.

If the parent directory link count is too low (likely directory inode

Subject: [PATCH 2732/2948] vmlinux.lds.h: Adjust symbol ordering in text
 output section
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the -ffunction-sections compiler option is enabled, each function
is placed in a separate section named .text.function_name rather than
putting all functions in a single .text section.

However, using -function-sections can cause problems with the
linker script. The comments included in include/asm-generic/vmlinux.lds.h
note these issues.:
  “TEXT_MAIN here will match .text.fixup and .text.unlikely if dead
   code elimination is enabled, so these sections should be converted
   to use ".." first.”

It is unclear whether there is a straightforward method for converting
a suffix to "..".

This patch modifies the order of subsections within the text output
section. Specifically, it changes current order:
  .text.hot, .text, .text_unlikely, .text.unknown, .text.asan
to the new order:
  .text.asan, .text.unknown, .text_unlikely, .text.hot, .text

Here is the rationale behind the new layout:

The majority of the code resides in three sections: .text.hot, .text,
and .text.unlikely, with .text.unknown containing a negligible amount.
.text.asan is only generated in ASAN builds.

The primary goal is to group code segments based on their execution
frequency (hotness).

First, we want to place .text.hot adjacent to .text. Since we cannot put
.text.hot after .text (Due to constraints with -ffunction-sections,
placing .text.hot after .text is problematic), we need to put
.text.hot before .text.

Then it comes to .text.unlikely, we cannot put it after .text (same
-ffunction-sections issue) . Therefore, we position .text.unlikely
before .text.hot.

.text.unknown and .tex.asan follow the same logic.

This revised ordering effectively reverses the original arrangement (for
.text.unlikely, .text.unknown, and .tex.asan), maintaining a similar level
of affinity between sections.

It also places .text.hot section at the beginning of a page to better
utilize the TLB entry.

Note that the limitation arises because the linker script employs glob
patterns instead of regular expressions for string matching. While there
is a method to maintain the current order using complex patterns, this
significantly complicates the pattern and increases the likelihood of
errors.

This patch also changes vmlinux.lds.S for the sparc64 architecture to
accommodate specific symbol placement requirements.

 for AutoFDO

Enable the machine function split optimization for AutoFDO in Clang.

Machine function split (MFS) is a pass in the Clang compiler that
splits a function into hot and cold parts. The linker groups all
cold blocks across functions together. This decreases hot code
fragmentation and improves iCache and iTLB utilization.

MFS requires a profile so this is enabled only for the AutoFDO builds.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add the build support for using Clang's Propeller optimizer. Like
AutoFDO, Propeller uses hardware sampling to gather information
about the frequency of execution of different code paths within a
binary. This information is then used to guide the compiler's
optimization decisions, resulting in a more efficient binary.

The support requires a Clang compiler LLVM 19 or later, and the
create_llvm_prof tool
(https://github.com/google/autofdo/releases/tag/v0.30.1). This
commit is limited to x86 platforms that support PMU features
like LBR on Intel machines and AMD Zen3 BRS.

Here is an example workflow for building an AutoFDO+Propeller
optimized kernel:

1) Build the kernel on the host machine, with AutoFDO and Propeller
   build config
      CONFIG_AUTOFDO_CLANG=y
      CONFIG_PROPELLER_CLANG=y
   then
      $ make LLVM=1 CLANG_AUTOFDO_PROFILE=<autofdo_profile>

“<autofdo_profile>” is the profile collected when doing a non-Propeller
AutoFDO build. This step builds a kernel that has the same optimization
level as AutoFDO, plus a metadata section that records basic block
information. This kernel image runs as fast as an AutoFDO optimized
kernel.

2) Install the kernel on test/production machines.

3) Run the load tests. The '-c' option in perf specifies the sample
   event period. We suggest using a suitable prime number,
   like 500009, for this purpose.
   For Intel platforms:
      $ perf record -e BR_INST_RETIRED.NEAR_TAKEN:k -a -N -b -c <count> \
        -o <perf_file> -- <loadtest>
   For AMD platforms:
      The supported system are: Zen3 with BRS, or Zen4 with amd_lbr_v2
      # To see if Zen3 support LBR:
      $ cat proc/cpuinfo | grep " brs"
      # To see if Zen4 support LBR:
      $ cat proc/cpuinfo | grep amd_lbr_v2
      # If the result is yes, then collect the profile using:
      $ perf record --pfm-events RETIRED_TAKEN_BRANCH_INSTRUCTIONS:k -a \
        -N -b -c <count> -o <perf_file> -- <loadtest>

4) (Optional) Download the raw perf file to the host machine.

5) Generate Propeller profile:
   $ create_llvm_prof --binary=<vmlinux> --profile=<perf_file> \
     --format=propeller --propeller_output_module_name \
     --out=<propeller_profile_prefix>_cc_profile.txt \
     --propeller_symorder=<propeller_profile_prefix>_ld_profile.txt

   “create_llvm_prof” is the profile conversion tool, and a prebuilt
   binary for linux can be found on
   https://github.com/google/autofdo/releases/tag/v0.30.1 (can also build
   from source).

   "<propeller_profile_prefix>" can be something like
   "/home/user/dir/any_string".

   This command generates a pair of Propeller profiles:
   "<propeller_profile_prefix>_cc_profile.txt" and
   "<propeller_profile_prefix>_ld_profile.txt".

6) Rebuild the kernel using the AutoFDO and Propeller profile files.
      CONFIG_AUTOFDO_CLANG=y
      CONFIG_PROPELLER_CLANG=y
   and
      $ make LLVM=1 CLANG_AUTOFDO_PROFILE=<autofdo_profile> \
        CLANG_PROPELLER_PROFILE_PREFIX=<propeller_profile_prefix>

+=====================================
+Using Propeller with the Linux kernel
+=====================================
+
+This enables Propeller build support for the kernel when using Clang
+compiler. Propeller is a profile-guided optimization (PGO) method used
+to optimize binary executables. Like AutoFDO, it utilizes hardware
+sampling to gather information about the frequency of execution of
+different code paths within a binary. Unlike AutoFDO, this information
+is then used right before linking phase to optimize (among others)
+block layout within and across functions.
+
+A few important notes about adopting Propeller optimization:
+
+#. Although it can be used as a standalone optimization step, it is
+   strongly recommended to apply Propeller on top of AutoFDO,
+   AutoFDO+ThinLTO or Instrument FDO. The rest of this document
+   assumes this paradigm.
+
+#. Propeller uses another round of profiling on top of
+   AutoFDO/AutoFDO+ThinLTO/iFDO. The whole build process involves
+   "build-afdo - train-afdo - build-propeller - train-propeller -
+   build-optimized".
+
+#. Propeller requires LLVM 19 release or later for Clang/Clang++
+   and the linker(ld.lld).
+
+#. In addition to LLVM toolchain, Propeller requires a profiling
+   conversion tool: https://github.com/google/autofdo with a release
+   after v0.30.1: https://github.com/google/autofdo/releases/tag/v0.30.1.
+
+The Propeller optimization process involves the following steps:
+
+#. Initial building: Build the AutoFDO or AutoFDO+ThinLTO binary as
+   you would normally do, but with a set of compile-time / link-time
+   flags, so that a special metadata section is created within the
+   kernel binary. The special section is only intend to be used by the
+   profiling tool, it is not part of the runtime image, nor does it
+   change kernel run time text sections.
+
+#. Profiling: The above kernel is then run with a representative
+   workload to gather execution frequency data. This data is collected
+   using hardware sampling, via perf. Propeller is most effective on
+   platforms supporting advanced PMU features like LBR on Intel
+   machines. This step is the same as profiling the kernel for AutoFDO
+   (the exact perf parameters can be different).
+
+#. Propeller profile generation: Perf output file is converted to a
+   pair of Propeller profiles via an offline tool.
+
+#. Optimized build: Build the AutoFDO or AutoFDO+ThinLTO optimized
+   binary as you would normally do, but with a compile-time /
+   link-time flag to pick up the Propeller compile time and link time
+   profiles. This build step uses 3 profiles - the AutoFDO profile,
+   the Propeller compile-time profile and the Propeller link-time
+   profile.
+
+#. Deployment: The optimized kernel binary is deployed and used
+   in production environments, providing improved performance
+   and reduced latency.
+
+Preparation
+===========
+
+Configure the kernel with::
+
+   CONFIG_AUTOFDO_CLANG=y
+   CONFIG_PROPELLER_CLANG=y
+
+Customization
+=============
+
+The default CONFIG_PROPELLER_CLANG setting covers kernel space objects
+for Propeller builds. One can, however, enable or disable Propeller build
+for individual files and directories by adding a line similar to the
+following to the respective kernel Makefile:
+
+- For enabling a single file (e.g. foo.o)::
+
+   PROPELLER_PROFILE_foo.o := y
+
+- For enabling all files in one directory::
+
+   PROPELLER_PROFILE := y
+
+- For disabling one file::
+
+   PROPELLER_PROFILE_foo.o := n
+
+- For disabling all files in one directory::
+
+   PROPELLER__PROFILE := n
+
+
+Workflow
+========
+
+Here is an example workflow for building an AutoFDO+Propeller kernel:
+
+1) Assuming an AutoFDO profile is already collected following
+   instructions in the AutoFDO document, build the kernel on the host
+   machine, with AutoFDO and Propeller build configs ::
+
+      CONFIG_AUTOFDO_CLANG=y
+      CONFIG_PROPELLER_CLANG=y
+
+   and ::
+
+      $ make LLVM=1 CLANG_AUTOFDO_PROFILE=<autofdo-profile-name>
+
+2) Install the kernel on the test machine.
+
+3) Run the load tests. The '-c' option in perf specifies the sample
+   event period. We suggest using a suitable prime number, like 500009,
+   for this purpose.
+
+   - For Intel platforms::
+
+      $ perf record -e BR_INST_RETIRED.NEAR_TAKEN:k -a -N -b -c <count> -o <perf_file> -- <loadtest>
+
+   - For AMD platforms::
+
+      $ perf record --pfm-event RETIRED_TAKEN_BRANCH_INSTRUCTIONS:k -a -N -b -c <count> -o <perf_file> -- <loadtest>
+
+   Note you can repeat the above steps to collect multiple <perf_file>s.
+
+4) (Optional) Download the raw perf file(s) to the host machine.
+
+5) Use the create_llvm_prof tool (https://github.com/google/autofdo) to
+   generate Propeller profile. ::
+
+      $ create_llvm_prof --binary=<vmlinux> --profile=<perf_file>
+                         --format=propeller --propeller_output_module_name
+                         --out=<propeller_profile_prefix>_cc_profile.txt
+                         --propeller_symorder=<propeller_profile_prefix>_ld_profile.txt
+
+   "<propeller_profile_prefix>" can be something like "/home/user/dir/any_string".
+
+   This command generates a pair of Propeller profiles:
+   "<propeller_profile_prefix>_cc_profile.txt" and
+   "<propeller_profile_prefix>_ld_profile.txt".
+
+   If there are more than 1 perf_file collected in the previous step,
+   you can create a temp list file "<perf_file_list>" with each line
+   containing one perf file name and run::
+
+      $ create_llvm_prof --binary=<vmlinux> --profile=@<perf_file_list>
+                         --format=propeller --propeller_output_module_name
+                         --out=<propeller_profile_prefix>_cc_profile.txt
+                         --propeller_symorder=<propeller_profile_prefix>_ld_profile.txt
+
+6) Rebuild the kernel using the AutoFDO and Propeller
+   profiles. ::
+
+      CONFIG_AUTOFDO_CLANG=y
+      CONFIG_PROPELLER_CLANG=y
+
+   and ::
+
+      $ make LLVM=1 CLANG_AUTOFDO_PROFILE=<profile_file> CLANG_PROPELLER_PROFILE_PREFIX=<propeller_profile_prefix>

Subject: [PATCH 2737/2948] kbuild: Fix Propeller build option

The '-fbasic-block-sections=labels' option has been deprecated in tip
of tree clang (20.0.0) [1]. While the option still works, a warning is
emitted:

  clang: warning: argument '-fbasic-block-sections=labels' is deprecated, use '-fbasic-block-address-map' instead [-Wdeprecated]

Add a version check to set the proper option.

Subject: [PATCH 2738/2948] Rename .data.unlikely to .data..unlikely

Commit 7ccaba5314ca ("consolidate WARN_...ONCE() static variables")
was intended to collect all .data.unlikely sections into one chunk.
However, this has not worked when CONFIG_LD_DEAD_CODE_DATA_ELIMINATION
or CONFIG_LTO_CLANG is enabled, because .data.unlikely matches the
.data.[0-9a-zA-Z_]* pattern in the DATA_MAIN macro.

Commit cb87481ee89d ("kbuild: linker script do not match C names unless
LD_DEAD_CODE_DATA_ELIMINATION is configured") was introduced to suppress
the issue for the default CONFIG_LD_DEAD_CODE_DATA_ELIMINATION=n case,
providing a minimal fix for stable backporting. We were aware this did

Subject: [PATCH 2739/2948] Rename .data.once to .data..once to fix resetting
 WARN*_ONCE

Commit b1fca27d384e ("kernel debug: support resetting WARN*_ONCE")
added support for clearing the state of once warnings. However,
it is not functional when CONFIG_LD_DEAD_CODE_DATA_ELIMINATION or
CONFIG_LTO_CLANG is enabled, because .data.once matches the
.data.[0-9a-zA-Z_]* pattern in the DATA_MAIN macro.

Commit cb87481ee89d ("kbuild: linker script do not match C names unless
LD_DEAD_CODE_DATA_ELIMINATION is configured") was introduced to suppress
the issue for the default CONFIG_LD_DEAD_CODE_DATA_ELIMINATION=n case,
providing a minimal fix for stable backporting. We were aware this did
not address the issue for CONFIG_LD_DEAD_CODE_DATA_ELIMINATION=y. The
plan was to apply correct fixes and then revert cb87481ee89d. [1]

Seven years have passed since then, yet the #ifdef workaround remains in
place. Meanwhile, commit b1fca27d384e introduced the .data.once section,
and commit dc5723b02e52 ("kbuild: add support for Clang LTO") extended
the #ifdef.

Using a ".." separator in the section name fixes the issue for
CONFIG_LD_DEAD_CODE_DATA_ELIMINATION and CONFIG_LTO_CLANG.

Subject: [PATCH 2740/2948] kbuild: deb-pkg: Don't fail if modules.order is
 missing

Kernels built without CONFIG_MODULES might still want to create -dbg deb
packages but install_linux_image_dbg() assumes modules.order always
exists. This obviously isn't true if no modules were built, so we should
skip reading modules.order in that case.

Subject: [PATCH 2742/2948] kbuild: add $(objtree)/ prefix to some in-kernel
 build artifacts

$(objtree) refers to the top of the output directory of kernel builds.

This commit adds the explicit $(objtree)/ prefix to build artifacts
needed for building external modules.

This change has no immediate impact, as the top-level Makefile
currently defines:

  objtree         := .

This commit prepares for supporting the building of external modules
in a different directory.

Subject: [PATCH 2745/2948] smb: client: allow more DFS referrals to be cached

In some DFS setups, a single DFS share may contain hundreds of DFS
links and increasing the DFS cache to allow more referrals to be
cached improves DFS failover as the client will likely find a cached
DFS referral when reconnecting and then avoiding unnecessary remounts.

Subject: [PATCH 2748/2948] smb: client: don't try following DFS links in
 cifs_tree_connect()

We can't properly support chasing DFS links in cifs_tree_connect()
because

  (1) We don't support creating new sessions while we're reconnecting,
      which would be required for DFS interlinks.

  (2) ->is_path_accessible() can't be called from cifs_tree_connect()
     as it would deadlock with smb2_reconnect().  This is required for
     checking if new DFS target is a nested DFS link.

By unconditionally trying to get an DFS referral from new DFS target
isn't correct because if the new DFS target (interlink) is an DFS
standalone namespace, then we would end up getting -ELOOP and then
potentially leaving tcon disconnected.

Subject: [PATCH 2749/2948] smb: client: fix noisy message when mounting shares

When the client unconditionally attempts to get an DFS referral to
check if share is DFS, some servers may return different errors that
aren't handled in smb2_get_dfs_refer(), so the following will be
logged in dmesg:

	CIFS: VFS: \\srv\IPC$ smb2_get_dfs_refer: ioctl error...

which can confuse some users while mounting an SMB share.

Fix this by logging such error with FYI.

Subject: [PATCH 2750/2948] smb: During unmount, ensure all cached dir
 instances drop their dentry

The unmount process (cifs_kill_sb() calling close_all_cached_dirs()) can
race with various cached directory operations, which ultimately results
in dentries not being dropped and these kernel BUGs:

BUG: Dentry ffff88814f37e358{i=1000000000080,n=/}  still in use (2) [unmount of cifs cifs]
VFS: Busy inodes after unmount of cifs (cifs)
------------[ cut here ]------------
kernel BUG at fs/super.c:661!

This happens when a cfid is in the process of being cleaned up when, and
has been removed from the cfids->entries list, including:

- Receiving a lease break from the server
- Server reconnection triggers invalidate_all_cached_dirs(), which
  removes all the cfids from the list
- The laundromat thread decides to expire an old cfid.

To solve these problems, dropping the dentry is done in queued work done
in a newly-added cfid_put_wq workqueue, and close_all_cached_dirs()
flushes that workqueue after it drops all the dentries of which it's
aware. This is a global workqueue (rather than scoped to a mount), but
the queued work is minimal.

The final cleanup work for cleaning up a cfid is performed via work
queued in the serverclose_wq workqueue; this is done separate from
dropping the dentries so that close_all_cached_dirs() doesn't block on
any server operations.

Both of these queued works expect to invoked with a cfid reference and
a tcon reference to avoid those objects from being freed while the work
is ongoing.

While we're here, add proper locking to close_all_cached_dirs(), and
locking around the freeing of cfid->dentry.

Fixes: ebe98f1447bb ("cifs: enable caching of directories for which a lease is held")

Subject: [PATCH 2751/2948] rust: fix up formatting after merge

When I merged the rust 'use' imports, I didn't realize that there's
an offical preferred idiomatic format - so while it all worked fine,
it doesn't match what 'make rustfmt' wants to make it.

Fix it up appropriately.

Subject: [PATCH 2752/2948] apparmor: allocate xmatch for nullpdb inside
 aa_alloc_null

attach->xmatch was not set when allocating a null profile, which is used in
complain mode to allocate a learning profile. This was causing downstream
failures in find_attach, which expected a valid xmatch but did not find
one under a certain sequence of profile transitions in complain mode.

This patch ensures the xmatch is set up properly for null profiles.

Subject: [PATCH 2753/2948] apparmor: properly handle cx/px lookup failure for
 complain

mode profiles

When a cx/px lookup fails, apparmor would deny execution of the binary
even in complain mode (where it would audit as allowing execution while
actually denying it). Instead, in complain mode, create a new learning
profile, just as would have been done if the cx/px line wasn't there.

Subject: [PATCH 2754/2948] apparmor: add support for 2^24 states to the dfa
 state machine.

Currently the dfa state machine is limited by its default, next, and
check tables using u16. Allow loading of u32 tables, and if u16 tables
are loaded map them to u32.

The number of states allowed does not increase to 2^32 because the
base table uses the top 8 bits of its u32 for flags. Moving the flags
into a separate table allowing a full 2^32 bit range wil be done in
a separate patch.

Subject: [PATCH 2757/2948] apparmor: Remove unnecessary NULL check before
 kvfree()

Since kvfree() already checks if its argument is NULL, an additional
check before calling kvfree() is unnecessary and can be removed.

Remove it and the following Coccinelle/coccicheck warning reported by
ifnullfree.cocci:

  WARNING: NULL check before some freeing functions is not needed

Subject: [PATCH 2758/2948] apparmor: Remove deadcode

aa_label_audit, aa_label_find, aa_label_seq_print and aa_update_label_name
were added by commit
f1bd904175e8 ("apparmor: add the base fns() for domain labels")
but never used.

aa_profile_label_perm was added by commit
637f688dc3dc ("apparmor: switch from profiles to using labels on contexts")
but never used.

aa_secid_update was added by commit
c092921219d2 ("apparmor: add support for mapping secids and using secctxes")
but never used.

aa_split_fqname has been unused since commit
3664268f19ea ("apparmor: add namespace lookup fns()")

aa_lookup_profile has been unused since commit
93c98a484c49 ("apparmor: move exec domain mediation to using labels")

aa_audit_perms_cb was only used by aa_profile_label_perm (see above).

All of these commits are from around 2017.

Remove them.

Add a comment to unpack_perm to document the first entry in the packed
perms struct is reserved, and make a non-functional change of unpacking
to a temporary stack variable named "reserved" to help suppor the
documentation of which value is reserved.

Subject: [PATCH 2762/2948] apparmor: document capability.c:profile_capable ad
 ptr not being NULL

The profile_capabile function takes a struct apparmor_audit_data *ad,
which is documented as possibly being NULL. However, the single place that
calls this function never passes it a NULL ad. If we were ever to call
profile_capable with a NULL ad elsewhere, we would need to rework the
function, as its very first use of ad is to dereference ad->class without
checking if ad is NULL.

Thus, document profile_capable's ad parameter as not accepting NULL.

Subject: [PATCH 2763/2948] apparmor: add a cache entry expiration time aging
 out capability audit cache

When auditing capabilities, AppArmor uses a per-CPU, per-profile cache
such that the same capability for the same profile doesn't get repeatedly
audited, with the original goal of reducing audit logspam. However, this
cache does not have an expiration time, resulting in confusion when a
profile is shared across binaries (for example) and an expected DENIED
audit entry doesn't appear, despite the cache entry having been populated
much longer ago. This confusion was exacerbated by the per-CPU nature of
the cache resulting in the expected entries sporadically appearing when
the later denial+audit occurred on a different CPU.

To resolve this, record the last time a capability was audited for a
profile and add a timestamp expiration check before doing the audit.

v1 -> v2:
 - Hardcode a longer timeout and drop the patches making it a sysctl,
   after discussion with John Johansen.
 - Cache the expiration time instead of the last-audited time. This value
   can never be zero, which lets us drop the kernel_cap_t caps field from
   the cache struct.

Subject: [PATCH 2764/2948] apparmor: audit_cap dedup based on subj_cred
 instead of profile

The previous audit_cap cache deduping was based on the profile that was
being audited. This could cause confusion due to the deduplication then
occurring across multiple processes, which could happen if multiple
instances of binaries matched the same profile attachment (and thus ran
under the same profile) or a profile was attached to a container and its
processes.

Instead, perform audit_cap deduping over ad->subj_cred, which ensures the
deduping only occurs across a single process, instead of across all
processes that match the current one's profile.

Subject: [PATCH 2773/2948] powerpc/prom_init: Fixup missing powermac
 #size-cells

On some powermacs `escc` nodes are missing `#size-cells` properties,
which is deprecated and now triggers a warning at boot since commit
045b14ca5c36 ("of: WARN on deprecated #address-cells/#size-cells
handling").

For example:

  Missing '#size-cells' in /pci@f2000000/mac-io@c/escc@13000
  WARNING: CPU: 0 PID: 0 at drivers/of/base.c:133 of_bus_n_size_cells+0x98/0x108
  Hardware name: PowerMac3,1 7400 0xc0209 PowerMac
  ...
  Call Trace:
    of_bus_n_size_cells+0x98/0x108 (unreliable)
    of_bus_default_count_cells+0x40/0x60
    __of_get_address+0xc8/0x21c

    pmz_console_init+0x10/0x48
    console_init+0xcc/0x138
    start_kernel+0x5c4/0x694

As powermacs boot via prom_init it's possible to add the missing
properties to the device tree during boot, avoiding the warning. Note
that `escc-legacy` nodes are also missing `#size-cells` properties, but
they are skipped by the macio driver, so leave them alone.

Avoid leaking a tcon ref when a lease break races with opening the

cached_dir_offload_close, since cfid->tcon is still NULL.

Subject: [PATCH 2776/2948] ALSA: ump: Fix evaluation of MIDI 1.0 FB info

The m1.0 field of UMP Function Block info specifies whether the given
FB is a MIDI 1.0 port or not.  When implementing the UMP support on
Linux, I somehow interpreted as if it were bit flags, but the field is
actually an enumeration from 0 to 2, where 2 means MIDI 1.0 *and* low
speed.

This patch corrects the interpretation and sets the right bit flags
depending on the m1.0 field of FB Info.  This effectively fixes the
missing detection of MIDI 1.0 FB when m1.0 is 2.

Subject: [PATCH 2779/2948] i2c: Introduce OF component probe function

Some devices are designed and manufactured with some components having
multiple drop-in replacement options. These components are often
connected to the mainboard via ribbon cables, having the same signals
and pin assignments across all options. These may include the display
panel and touchscreen on laptops and tablets, and the trackpad on
laptops. Sometimes which component option is used in a particular device
can be detected by some firmware provided identifier, other times that
information is not available, and the kernel has to try to probe each
device.

This change attempts to make the "probe each device" case cleaner. The
current approach is to have all options added and enabled in the device
tree. The kernel would then bind each device and run each driver's probe
function. This works, but has been broken before due to the introduction
of asynchronous probing, causing multiple instances requesting "shared"
resources, such as pinmuxes, GPIO pins, interrupt lines, at the same
time, with only one instance succeeding. Work arounds for these include
moving the pinmux to the parent I2C controller, using GPIO hogs or
pinmux settings to keep the GPIO pins in some fixed configuration, and
requesting the interrupt line very late. Such configurations can be seen
on the MT8183 Krane Chromebook tablets, and the Qualcomm sc8280xp-based
Lenovo Thinkpad 13S.

Instead of this delicate dance between drivers and device tree quirks,
this change introduces a simple I2C component probe function. For a
given class of devices on the same I2C bus, it will go through all of
them, doing a simple I2C read transfer and see which one of them responds.
It will then enable the device that responds.

This requires some minor modifications in the existing device tree. The
status for all the device nodes for the component options must be set
to "fail-needs-probe". This makes it clear that some mechanism is
needed to enable one of them, and also prevents the prober and device
drivers running at the same time.

Subject: [PATCH 2780/2948] i2c: of-prober: Add simple helpers for regulator
 support

Add helpers to do regulator management for the I2C OF component prober.
Components that the prober intends to probe likely require their
regulator supplies be enabled, and GPIOs be toggled to enable them or
bring them out of reset before they will respond to probe attempts.
GPIOs will be handled in the next patch.

The assumption is that the same class of components to be probed are
always connected in the same fashion with the same regulator supply
and GPIO. The names may vary due to binding differences, but the
physical layout does not change.

This set of helpers supports at most one regulator supply. The user
must specify the node from which the supply is retrieved. The supply
name and the amount of time to wait after the supply is enabled are
also given by the user.

Subject: [PATCH 2781/2948] i2c: of-prober: Add GPIO support to simple helpers

Add GPIO support to the simple helpers for the I2C OF component prober.
Components that the prober intends to probe likely require their
regulator supplies be enabled, and GPIOs be toggled to enable them or
bring them out of reset before they will respond to probe attempts.
Regulator supplies were handled in the previous patch.

The assumption is that the same class of components to be probed are
always connected in the same fashion with the same regulator supply
and GPIO. The names may vary due to binding differences, but the
physical layout does not change.

This supports at most one GPIO pin. The user must specify the GPIO name,
the polarity, and the amount of time to wait after the GPIO is toggled.
Devices with more than one GPIO pin likely require specific power
sequencing beyond what generic code can easily support.

Subject: [PATCH 2782/2948] platform/chrome: Introduce device tree hardware
 prober

Some devices are designed and manufactured with some components having
multiple drop-in replacement options. These components are often
connected to the mainboard via ribbon cables, having the same signals
and pin assignments across all options. These may include the display
panel and touchscreen on laptops and tablets, and the trackpad on
laptops. Sometimes which component option is used in a particular device
can be detected by some firmware provided identifier, other times that
information is not available, and the kernel has to try to probe each
device.

This change attempts to make the "probe each device" case cleaner. The
current approach is to have all options added and enabled in the device
tree. The kernel would then bind each device and run each driver's probe
function. This works, but has been broken before due to the introduction
of asynchronous probing, causing multiple instances requesting "shared"
resources, such as pinmuxes, GPIO pins, interrupt lines, at the same
time, with only one instance succeeding. Work arounds for these include
moving the pinmux to the parent I2C controller, using GPIO hogs or
pinmux settings to keep the GPIO pins in some fixed configuration, and
requesting the interrupt line very late. Such configurations can be seen
on the MT8183 Krane Chromebook tablets, and the Qualcomm sc8280xp-based
Lenovo Thinkpad 13S.

Instead of this delicate dance between drivers and device tree quirks,
this change introduces a simple I2C component prober. For any given
class of devices on the same I2C bus, it will go through all of them,
doing a simple I2C read transfer and see which one of them responds.
It will then enable the device that responds.

This requires some minor modifications in the existing device tree.
The status for all the device nodes for the component options must be
set to "fail-needs-probe". This makes it clear that some mechanism is
needed to enable one of them, and also prevents the prober and device
drivers running at the same time.

Subject: [PATCH 2783/2948] arm64: dts: mediatek: mt8173-elm-hana: Mark
 touchscreens and trackpads as fail

Instead of having them all available, mark them all as "fail-needs-probe"
and have the implementation try to probe which one is present.

Also remove the shared resource workaround by moving the pinctrl entry
for the trackpad interrupt line back into the individual trackpad nodes.

Subject: [PATCH 2786/2948] ASoC: mediatek: Check num_codecs is not zero to
 avoid panic during probe
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Following commit 13f58267cda3 ("ASoC: soc.h: don't create dummy
Component via COMP_DUMMY()"), COMP_DUMMY() became an array with zero
length, and only gets populated with the dummy struct after the card is
registered. Since the sound card driver's probe happens before the card
registration, accessing any of the members of a dummy component during
probe will result in undefined behavior.

This can be observed in the mt8188 and mt8195 machine sound drivers. By
omitting a dai link subnode in the sound card's node in the Devicetree,
the default uninitialized dummy codec is used, and when its dai_name
pointer gets passed to strcmp() it results in a null pointer dereference
and a kernel panic.

In addition to that, set_card_codec_info() in the generic helpers file,
mtk-soundcard-driver.c, will populate a dai link with a dummy codec when
a dai link node is present in DT but with no codec property.

The result is that at probe time, a dummy codec can either be
uninitialized with num_codecs = 0, or be an initialized dummy codec,
with num_codecs = 1 and dai_name = "snd-soc-dummy-dai". In order to
accommodate for both situations, check that num_codecs is not zero
before accessing the codecs' fields but still check for the codec's dai
name against "snd-soc-dummy-dai" as needed.

While at it, also drop the check that dai_name is not null in the mt8192
driver, introduced in commit 4d4e1b6319e5 ("ASoC: mediatek: mt8192:
Check existence of dai_name before dereferencing"), as it is actually
redundant given the preceding num_codecs != 0 check.

Subject: [PATCH 2787/2948] ASoC: SOF: ipc3-topology: Convert the topology pin
 index to ALH dai index
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Intel SoundWire machine driver always uses Pin number 2 and above.
Currently, the pin number is used as the FW DAI index directly. As a
result, FW DAI 0 and 1 are never used. That worked fine because we use
up to 2 DAIs in a SDW link. Convert the topology pin index to ALH dai
index, the mapping is using 2-off indexing, iow, pin #2 is ALH dai #0.

The issue exists since beginning. And the Fixes tag is the first commit
that this commit can be applied.

Quoting myself from commit 2a010c412853 ("fs: don't block i_writecount during exec")

It seems we found out that someone is relying on this obscure behavior.
So revert the change.

Subject: [PATCH 2789/2948] s390/ap: Replace xchg() with WRITE_ONCE()

The result of xchg() is not used, and in addition it is used on a one byte
memory area which leads to inefficient code.

Use WRITE_ONCE() instead to achieve the same result with much less
generated code.

Subject: [PATCH 2790/2948] KVM: s390: Use try_cmpxchg() instead of cmpxchg()
 loops

Convert all cmpxchg() loops to try_cmpxchg() loops. With gcc 14 and the
usage of flag output operands in try_cmpxchg() this allows the compiler to
generate slightly better code.

Subject: [PATCH 2791/2948] KVM: s390: Remove one byte cmpxchg() usage

Within sca_clear_ext_call() cmpxchg() is used to clear one or two bytes
(depending on sca format). The cmpxchg() calls are not supposed to fail; if
so that would be a bug. Given that cmpxchg() usage on one and two byte
areas generates very inefficient code, replace them with block concurrent
WRITE_ONCE() calls, and remove the WARN_ON().

kvm_s390_update_topology_change_report() modifies a single bit within
sca_utility using cmpxchg(). Given that the size of the sca_utility union
is two bytes this generates very inefficient code. Change the size to four
bytes, so better code can be generated.

Even though the size of sca_utility doesn't reflect architecture anymore
this seems to be the easiest and most pragmatic approach to avoid
inefficient code.

Subject: [PATCH 2793/2948] s390/mm: Rearrange region-third and segment table
 entry SW bits

Rearrange region-third and segment table entry SW bits, in order to
make room for future encoding of region/segment table swap entries.

Also adjust _SEGMENT_ENTRY_GMAP_UC and _SEGMENT_ENTRY_GMAP_IN bits in
gmap code. Those should only apply for gmap PMDs, and not really depend
on or conflict with host PMD bits, but for consistency also adjust them:
- _SEGMENT_ENTRY_GMAP_UC "dirty (migration)" was using the same bit as
  _SEGMENT_ENTRY_SOFT_DIRTY in the host PMD -> make it use the new
  SOFT_DIRTY bit 63 (0x0002)
- _SEGMENT_ENTRY_GMAP_IN "invalidation notify bit" was using 0x8000,
  which was an unused bit in the host PMD, that is now used for
  _SEGMENT_ENTRY_WRITE -> make it use bit 52 (0x0800) instead, which is
  still unused in the host PMD

This is a prerequisite for hugetlbfs PTE_MARKER support on s390, which
is needed to fix a regression introduced with commit 8a13897fb0da
("mm: userfaultfd: support UFFDIO_POISON for hugetlbfs"). That commit
depends on the availability of swap entries for hugetlbfs, which were
not available for s390 so far.

Subject: [PATCH 2794/2948] s390/mm: Introduce region-third and segment table
 entry present bits

Introduce region-third and segment table entry present SW bits, and adjust
pmd/pud_present() accordingly.

Also add pmd/pud_present() checks to pmd/pud_leaf(), to return false for
future swap entries. Same logic applies to pmd_trans_huge(), make that
return pmd_leaf() instead of duplicating the same check.

huge_pte_offset() also needs to be adjusted, current code would return
NULL for !pud_present(). Use the same logic as in the generic version,
which allows for !pud_present() swap entries.

Similar to PTE, bit 63 can be used for the new SW present bit in region
and segment table entries. For segment-table entries (PMD) the architecture
says that "Bits 62-63 are available for programming", so they are safe to
use. The same is true for large leaf region-third-table entries (PUD).

However, for non-leaf region-third-table entries, bits 62-63 indicate the
TABLE LENGTH and both must be set to 1. But such entries would always be
considered as present, so it is safe to use bit 63 as PRESENT bit for PUD.
They also should not conflict with bit 62 potentially later used for
preserving SOFT_DIRTY in swap entries, because they are not swap entries.

Valid PMDs / PUDs should always have the present bit set, so add it to
the various pgprot defines, and also _SEGMENT_ENTRY which is OR'ed e.g.
in pmd_populate(). _REGION3_ENTRY wouldn't need any change, as the present
bit is already included in the TABLE LENGTH, but also explicitly add it
there, for completeness, and just in case the bit would ever be changed.

gmap code needs some adjustment, to also OR the _SEGMENT_ENTRY, like it
is already done gmap_shadow_pgt() when creating new PMDs, but not in
__gmap_link(). Otherwise, the gmap PMDs would not be considered present,
e.g. when using pmd_leaf() checks in gmap code. The various WARN_ON
checks in gmap code also need adjustment, to tolerate the new present
bit.

This is a prerequisite for hugetlbfs PTE_MARKER support on s390, which
is needed to fix a regression introduced with commit 8a13897fb0da
("mm: userfaultfd: support UFFDIO_POISON for hugetlbfs"). That commit
depends on the availability of swap entries for hugetlbfs, which were
not available for s390 so far.

Subject: [PATCH 2795/2948] s390/mm: Introduce region-third and segment table
 swap entries

Introduce region-third (PUD) and segment table (PMD) swap entries, and
make hugetlbfs RSTE <-> PTE conversion code aware of them, so that they
can be used for hugetlbfs PTE_MARKER entries. Future work could also
build on this to enable THP_SWAP and THP_MIGRATION for s390.

Similar to PTE swap entries, bits 0-51 can be used to store the swap
offset, but bits 57-61 cannot be used for swap type because that overlaps
with the INVALID and TABLE TYPE bits. PMD/PUD swap entries must be invalid,
and have a correct table type so that pud_folded() check still works.

Bits 53-57 can be used for swap type, but those include the PROTECT bit.
So unlike swap PTEs, the PROTECT bit cannot be used to mark the swap entry.
Use the "Common-Segment/Region" bit 59 instead for that.

Also remove the !MACHINE_HAS_NX check in __set_huge_pte_at(). Otherwise,
that would clear the _SEGMENT_ENTRY_NOEXEC bit also for swap entries, where
it is used for encoding the swap type. The architecture only requires this
bit to be 0 for PTEs, with !MACHINE_HAS_NX, not for segment or region-third
entries. And the check is also redundant, because after __pte_to_rste()
conversion, for non-swap PTEs it would only be set if it was already set in
the PTE, which should never be the case for !MACHINE_HAS_NX.

This is a prerequisite for hugetlbfs PTE_MARKER support on s390, which
is needed to fix a regression introduced with commit 8a13897fb0da
("mm: userfaultfd: support UFFDIO_POISON for hugetlbfs"). That commit
depends on the availability of swap entries for hugetlbfs, which were
not available for s390 so far.

Subject: [PATCH 2796/2948] s390/mm: Add PTE_MARKER support for hugetlbfs
 mappings

Commit 8a13897fb0daa ("mm: userfaultfd: support UFFDIO_POISON for
hugetlbfs") added support for PTE_MARKER_POISONED for hugetlbfs, but
PTE_MARKER also needs support for swap entries. For s390, swap entries
were only supported on PTE level, not on the PMD/PUD levels that are used
for large hugetlbfs mappings.

Therefore, when writing a PTE_MARKER_POISONED entry, the resulting entry
on PMD/PUD level would be an invalid / empty entry. Further access would
then generate a pagefault loop, instead of the expected SIGBUS. It is a
loop inside the kernel, but interruptible and uffd fault handling also
calls schedule() in between, so at least it won't completely block the
system.

Previous commits prepared support for swap entries on PMD/PUD levels.
PTE_MARKER support for hugetlbfs can now be enabled by simply adding an
extra is_pte_marker() check to huge_pte_none_mostly(). Fault handling
code also needs to be adjusted to expect the VM_FAULT_HWPOISON_LARGE
fault flag, which was not possible on s390 before.

Subject: [PATCH 2798/2948] io_uring: fix corner case forgetting to vunmap

io_pages_unmap() is a bit tricky in trying to figure whether the pages
were previously vmap'ed or not. In particular If there is juts one page
it belives there is no need to vunmap. Paired io_pages_map(), however,
could've failed io_mem_alloc_compound() and attempted to
io_mem_alloc_single(), which does vmap, and that leads to unpaired vmap.

The solution is to fail if io_mem_alloc_compound() can't allocate a
single page. That's the easiest way to deal with it, and those two
functions are getting removed soon, so no need to overcomplicate it.

Subject: [PATCH 2800/2948] kbuild: change working directory to external module
 directory with M=

Currently, Kbuild always operates in the output directory of the kernel,
even when building external modules. This increases the risk of external
module Makefiles attempting to write to the kernel directory.

This commit switches the working directory to the external module
directory, allowing the removal of the $(KBUILD_EXTMOD)/ prefix from
some build artifacts.

The command for building external modules maintains backward
compatibility, but Makefiles that rely on working in the kernel
directory may break. In such cases, $(objtree) and $(srctree) should
be used to refer to the output and source directories of the kernel.

The appearance of the build log will change as follows:

[Before]

  $ make -C /path/to/my/linux M=/path/to/my/externel/module
  make: Entering directory '/path/to/my/linux'
    CC [M]  /path/to/my/externel/module/helloworld.o
    MODPOST /path/to/my/externel/module/Module.symvers
    CC [M]  /path/to/my/externel/module/helloworld.mod.o
    CC [M]  /path/to/my/externel/module/.module-common.o
    LD [M]  /path/to/my/externel/module/helloworld.ko
  make: Leaving directory '/path/to/my/linux'

[After]

  $ make -C /path/to/my/linux M=/path/to/my/externel/module
  make: Entering directory '/path/to/my/linux'
  make[1]: Entering directory '/path/to/my/externel/module'
    CC [M]  helloworld.o
    MODPOST Module.symvers
    CC [M]  helloworld.mod.o
    CC [M]  .module-common.o
    LD [M]  helloworld.ko
  make[1]: Leaving directory '/path/to/my/externel/module'
  make: Leaving directory '/path/to/my/linux'

Printing "Entering directory" twice is cumbersome. This will be
addressed later.

Subject: [PATCH 2801/2948] kbuild: remove extmod_prefix, MODORDER,
 MODULES_NSDEPS variables

With the previous changes, $(extmod_prefix), $(MODORDER), and
$(MODULES_NSDEPS) are constant. (empty, modules.order, and
modules.nsdeps, respectively).

Remove these variables and hard-code their values.

Subject: [PATCH 2802/2948] kbuild: support building external modules in a
 separate build directory

There has been a long-standing request to support building external
modules in a separate build directory.

This commit introduces a new environment variable, KBUILD_EXTMOD_OUTPUT,
and its shorthand Make variable, MO.

A simple usage:

 $ make -C <kernel-dir> M=<module-src-dir> MO=<module-build-dir>

Subject: [PATCH 2803/2948] kbuild: support -fmacro-prefix-map for external
 modules

This commit makes -fmacro-prefix-map work for external modules built in
a separate output directory. It improves the reproducibility of external
modules and provides the benefits described in commit a73619a845d5
("kbuild: use -fmacro-prefix-map to make __FILE__ a relative path").

When building_out_of_srctree is not defined (e.g., when the kernel or
external module is built in the source directory), this option is
unnecessary.

Subject: [PATCH 2805/2948] kbuild: make wrapper Makefile more convenient for
 external modules

When Kbuild starts building in a separate output directory, it generates
a wrapper Makefile, allowing you to invoke 'make' from the output
directory.

This commit makes it more convenient, so you can invoke 'make' without
M= or MO=.

First, you need to build external modules in a separate directory:

  $ make M=/path/to/module/source/dir MO=/path/to/module/build/dir

Once the wrapper Makefile is generated in /path/to/module/build/dir,
you can proceed as follows:

  $ cd /path/to/module/build/dir
  $ make

Subject: [PATCH 2806/2948] kbuild: allow to start building external modules in
 any directory

Unless an explicit O= option is provided, external module builds must
start from the kernel directory.

This can be achieved by using the -C option:

  $ make -C /path/to/kernel M=/path/to/external/module

This commit allows starting external module builds from any directory,
so you can also do the following:

  $ make -f /path/to/kernel/Makefile M=/path/to/external/module

The key difference is that the -C option changes the working directory
and parses the Makefile located there, while the -f option only
specifies the Makefile to use.

As shown in the examples in Documentation/kbuild/modules.rst, external
modules usually have a wrapper Makefile that allows you to build them
without specifying any make arguments. The Makefile typically contains
a rule as follows:

    KDIR ?= /path/to/kernel
    default:
            $(MAKE) -C $(KDIR) M=$(CURDIR) $(MAKECMDGOALS)

The log will appear as follows:

    $ make
    make -C /path/to/kernel M=/path/to/external/module
    make[1]: Entering directory '/path/to/kernel'
    make[2]: Entering directory '/path/to/external/module'
      CC [M]  helloworld.o
      MODPOST Module.symvers
      CC [M]  helloworld.mod.o
      CC [M]  .module-common.o
      LD [M]  helloworld.ko
    make[2]: Leaving directory '/path/to/external/module'
    make[1]: Leaving directory '/path/to/kernel'

This changes the working directory twice because the -C option first
switches to the kernel directory, and then Kbuild internally recurses
back to the external module directory.

With this commit, the wrapper Makefile can directly include the kernel
Makefile:

    KDIR ?= /path/to/kernel
    export KBUILD_EXTMOD := $(realpath $(dir $(lastword $(MAKEFILE_LIST))))
    include $(KDIR)/Makefile

This avoids unnecessary sub-make invocations:

    $ make
      CC [M]  helloworld.o
      MODPOST Module.symvers
      CC [M]  helloworld.mod.o
      CC [M]  .module-common.o
      LD [M]  helloworld.ko

This rule is unnecessary because you can generate foo/bar.symtypes

  $ make KBUILD_SYMTYPES=1 foo/bar.o

While compiling *.o is slower than preprocessing, the impact is
negligible. I prioritize keeping the code simpler.

Currently, objtool is disabled in scripts/Makefile.{modfinal,vmlinux}.

This commit moves rule_cc_o_c and rule_as_o_S to scripts/Makefile.lib
and set objtool-enabled to y there.

With this change, *.mod.o, .module-common.o,  builtin-dtb.o, and
vmlinux.export.o will now be covered by objtool.

Subject: [PATCH 2811/2948] kbuild: re-enable KCSAN for autogenerated *.mod.c
 intermediaries

This reverts commit 54babdc0343f ("kbuild: Disable KCSAN for
autogenerated *.mod.c intermediaries").

Now that objtool is enabled for *.mod.c, there is no need to filter
out CFLAGS_KCSAN.

I no longer see "Unpatched return thunk in use. This should not happen!"
error with KCSAN when loading a module.

Subject: [PATCH 2812/2948] kbuild: switch from lz4c to lz4 for compression

Replace lz4c with lz4 for kernel image compression.
Although lz4 and lz4c are functionally similar, lz4c has been deprecated
upstream since 2018. Since as early as Ubuntu 16.04 and Fedora 25, lz4
and lz4c have been packaged together, making it safe to update the
requirement from lz4c to lz4.

Consequently, some distributions and build systems, such as OpenEmbedded,
have fully transitioned to using lz4. OpenEmbedded core adopted this
change in commit fe167e082cbd ("bitbake.conf: require lz4 instead of
lz4c"), causing compatibility issues when building the mainline kernel
in the latest OpenEmbedded environment, as seen in the errors below.

This change also updates the LZ4 compression commands to make it backward
compatible by replacing stdin and stdout with the '-' option, due to some
unclear reason, the stdout keyword does not work for lz4 and '-' works for
both. In addition, this modifies the legacy '-c1' with '-9' which is also
compatible with both. This fixes the mainline kernel build failures with
the latest master OpenEmbedded builds associated with the mentioned
compatibility issues.

Subject: [PATCH 2813/2948] setlocalversion: work around "git describe"
 performance

Contrary to expectations, passing a single candidate tag to "git
describe" is slower than not passing any --match options.

  $ time git describe --debug
  ...
  traversed 10619 commits
  ...
  v6.12-rc5-63-g0fc810ae3ae1

  real    0m0.169s

  $ time git describe --match=v6.12-rc5 --debug
  ...
  traversed 1310024 commits
  v6.12-rc5-63-g0fc810ae3ae1

  real    0m1.281s

In fact, the --debug output shows that git traverses all or most of
history. For some repositories and/or git versions, those 1.3s are
actually 10-15 seconds.

This has been acknowledged as a performance bug in git [1], and a fix
is on its way [2]. However, no solution is yet in git.git, and even
when one lands, it will take quite a while before it finds its way to
a release and for $random_kernel_developer to pick that up.

So rewrite the logic to use plumbing commands. For each of the
candidate values of $tag, we ask: (1) is $tag even an annotated
tag? (2) Is it eligible to describe HEAD, i.e. an ancestor of
HEAD? (3) If so, how many commits are in $tag..HEAD?

I have tested that this produces the same output as the current script
for ~700 random commits between v6.9..v6.10. For those 700 commits,
and in my git repo, the 'make -s kernelrelease' command is on average
~4 times faster with this patch applied (geometric mean of ratios).

For the commit mentioned in Josh's original report [3], the
time-consuming part of setlocalversion goes from

$ time git describe --match=v6.12-rc5 c1e939a21eb1
v6.12-rc5-44-gc1e939a21eb1

real    0m1.210s

to

$ time git rev-list --count --left-right v6.12-rc5..c1e939a21eb1
0       44

real    0m0.037s

Set the -e option to ensure this script fails on any unexpected errors.

Without this change, the kernel build may continue running with an
incorrect string in include/config/kernel.release.

Currently, try_tag() returns 1 when the expected tag is not found as an
ancestor, but this is a case where the script should continue.

Subject: [PATCH 2815/2948] modpost: remove incorrect code in do_eisa_entry()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This function contains multiple bugs after the following commits:

 - ac551828993e ("modpost: i2c aliases need no trailing wildcard")
 - 6543becf26ff ("mod/file2alias: make modalias generation safe for cross compiling")

Commit ac551828993e inserted the following code to do_eisa_entry():

    else
            strcat(alias, "*");

This is incorrect because 'alias' is uninitialized. If it is not
NULL-terminated, strcat() could cause a buffer overrun.

Even if 'alias' happens to be zero-filled, it would output:

    MODULE_ALIAS("*");

This would match anything. As a result, the module could be loaded by
any unrelated uevent from an unrelated subsystem.

Commit ac551828993e introduced another bug.            

Prior to that commit, the conditional check was:

    if (eisa->sig[0])

This checked if the first character of eisa_device_id::sig was not '\0'.

However, commit ac551828993e changed it as follows:

    if (sig[0])

sig[0] is NOT the first character of the eisa_device_id::sig. The
type of 'sig' is 'char (*)[8]', meaning that the type of 'sig[0]' is
'char [8]' instead of 'char'. 'sig[0]' and 'symval' refer to the same
address, which never becomes NULL.

The correct conversion would have been:

    if ((*sig)[0])

However, this if-conditional was meaningless because the earlier change
in commit ac551828993e was incorrect.

This commit removes the entire incorrect code, which should never have
been executed.

Fixes: ac551828993e ("modpost: i2c aliases need no trailing wildcard")
Fixes: 6543becf26ff ("mod/file2alias: make modalias generation safe for cross compiling")

Subject: [PATCH 2817/2948] modpost: introduce module_alias_printf() helper

The generic ->do_entry() handler is currently limited to returning
a single alias string.

However, this is not flexible enough for several subsystems, which
currently require their own implementations:

 - do_usb_table()
 - do_of_table()
 - do_pnp_device_entry()
 - do_pnp_card_entries()

This commit introduces a helper function so that these special cases can
add multiple MODULE_ALIAS() and then migrate to the generic framework.

Subject: [PATCH 2818/2948] modpost: deduplicate MODULE_ALIAS() for all drivers

MODULE_DEVICE_TABLE(pnp_card, ...) may have duplicated IDs. For
instance, snd_ad1816a_pnpids[] in sound/isa/ad1816a/ad1816a.c includes
multiple occurrences of the "ADS7180" string within its .devs fields.

Currently, do_pnp_card_entries() handles deduplication on its own, but
this logic should be moved to a common helper function, as drivers in
other subsystems might also have similar duplication issues.

For example, drivers/media/i2c/s5c73m3/s5c73m3.mod.c contains duplicated
MODULE_ALIAS() entries because both s5c73m3-core.c and s5c73m3-spi.c
define the same compatible string.

This commit eliminates redundant MODULE_ALIAS() entries across all
drivers.

[Before]

  $ grep MODULE_ALIAS drivers/media/i2c/s5c73m3/s5c73m3.mod.c
  MODULE_ALIAS("i2c:S5C73M3");
  MODULE_ALIAS("of:N*T*Csamsung,s5c73m3");
  MODULE_ALIAS("of:N*T*Csamsung,s5c73m3C*");
  MODULE_ALIAS("of:N*T*Csamsung,s5c73m3");
  MODULE_ALIAS("of:N*T*Csamsung,s5c73m3C*");

[After]

  $ grep MODULE_ALIAS drivers/media/i2c/s5c73m3/s5c73m3.mod.c
  MODULE_ALIAS("i2c:S5C73M3");
  MODULE_ALIAS("of:N*T*Csamsung,s5c73m3");
  MODULE_ALIAS("of:N*T*Csamsung,s5c73m3C*");

From 6d3b3dd26fd71dde0b41478755a59ca30aaeb664 Mon Sep 17 00:00:00 2001
From: Masahiro Yamada <masahiroy@kernel.org>
Date: Wed, 20 Nov 2024 08:56:45 +0900
Subject: [PATCH 2821/2948] modpost: call module_alias_printf() from all
 do_*_entry() functions

The do_*_entry() functions cannot check the length of the given buffer.

Use module_alias_printf() helper consistently for these functions.

do_pnp_card_entries() no longer needs to iterate over the

Subject: [PATCH 2825/2948] modpost: convert do_usb_table() to a generic
 handler

do_usb_table() no longer needs to iterate over the usb_device_id array.

Convert it to a generic ->do_entry() handler.

This is the last special case. Clean up handle_moddevtable().

 MODULE_DEVICE_TABLE()

This commit renames the alias symbol, __mod_<type>__<name>_device_table
to __mod_device_table__<type>__<name>.

This change simplifies the code slightly, as there is no longer a need
to check both the prefix and suffix.

Subject: [PATCH 2829/2948] modpost: improve error messages in
 device_id_check()

The first error message in device_id_check() is obscure and can be
misleading because the cause of the error is unlikely to be found in
the struct definition in mod_devicetable.h.

This type of error occurs when an array is passed to an incorrect type
of MODULE_DEVICE_TABLE().

[Example 1]

    static const struct acpi_device_id foo_ids[] = {
            { "FOO" },
            { /* sentinel */ },
    };
    MODULE_DEVICE_TABLE(of, foo_ids);

Currently, modpost outputs a meaningless suggestion:

    ERROR: modpost: ...: sizeof(struct of_device_id)=200 is not a modulo of the size of section __mod_device_table__of__<identifier>=64.
    Fix definition of struct of_device_id in mod_devicetable.h

The root cause here is that MODULE_DEVICE_TABLE(of, ...) is used instead
of the correct MODULE_DEVICE_TABLE(acpi, ...).

This commit provides a more intuitive error message:

    ERROR: modpost: ...: type mismatch between foo_ids[] and MODULE_DEVICE_TABLE(of, ...)

The second error message, related to a missing terminator, is too
verbose.

[Example 2]

    static const struct acpi_device_id foo_ids[] = {
            { "FOO" },
    };
    MODULE_DEVICE_TABLE(acpi, foo_ids);

The current error message is overly long, and does not pinpoint the
incorrect array:

    ...: struct acpi_device_id is 32 bytes.  The last of 1 is:
    0x46 0x4f 0x4f 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
    ERROR: modpost: ...: struct acpi_device_id is not terminated with a NULL entry!

This commit changes it to a more concise error message, sufficient to
identify the incorrect array:

    ERROR: modpost: ...: foo_ids[] is not terminated with a NULL entry

Lastly, this commit squashes device_id_check() into do_table() and
changes fatal() into error(), allowing modpost to continue processing
other modules.

Python3 is necessary for running some scripts such as

Both scripts/package/kernel.spec and scripts/package/PKGBUILD already
list Python as the build dependency.

Do likewise for scripts/package/mkdebian.

Subject: [PATCH 2840/2948] net: phy: fix phy_ethtool_set_eee() incorrectly
 enabling LPI

When phy_ethtool_set_eee_noneg() detects a change in the LPI
parameters, it attempts to update phylib state and trigger the link
to cycle so the MAC sees the updated parameters.

However, in doing so, it sets phydev->enable_tx_lpi depending on
whether the EEE configuration allows the MAC to generate LPI without
taking into account the result of negotiation.

This can be demonstrated with a 1000base-T FD interface by:

 # ethtool --set-eee eno0 advertise 8   # cause EEE to be not negotiated
 # ethtool --set-eee eno0 tx-lpi off
 # ethtool --set-eee eno0 tx-lpi on

This results in being true, despite EEE not having been negotiated and:
 # ethtool --show-eee eno0
	EEE status: enabled - inactive
	Tx LPI: 250 (us)
	Supported EEE link modes:  100baseT/Full
	                           1000baseT/Full
	Advertised EEE link modes:  100baseT/Full
	                                         1000baseT/Full

Fix this by keeping track of whether EEE was negotiated via a new
eee_active member in struct phy_device, and include this state in
the decision whether phydev->enable_tx_lpi should be set.

Subject: [PATCH 2841/2948] tcp: Fix use-after-free of nreq in
 reqsk_timer_handler().

The cited commit replaced inet_csk_reqsk_queue_drop_and_put() with
__inet_csk_reqsk_queue_drop() and reqsk_put() in reqsk_timer_handler().

Then, oreq should be passed to reqsk_put() instead of req; otherwise
use-after-free of nreq could happen when reqsk is migrated but the
retry attempt failed (e.g. due to timeout).

Let's pass oreq to reqsk_put().

Subject: [PATCH 2842/2948] net_sched: sch_fq: don't follow the fast path if Tx
 is behind now

Recent kernels cause a lot of TCP retransmissions

[ ID] Interval           Transfer     Bitrate         Retr  Cwnd
[  5]   0.00-1.00   sec  2.24 GBytes  19.2 Gbits/sec  2767    442 KBytes
[  5]   1.00-2.00   sec  2.23 GBytes  19.1 Gbits/sec  2312    350 KBytes
                                                      ^^^^

Replacing the qdisc with pfifo makes retransmissions go away.

It appears that a flow may have a delayed packet with a very near
Tx time. Later, we may get busy processing Rx and the target Tx time
will pass, but we won't service Tx since the CPU is busy with Rx.
If Rx sees an ACK and we try to push more data for the delayed flow
we may fastpath the skb, not realizing that there are already "ready
to send" packets for this flow sitting in the qdisc.

Don't trust the fastpath if we are "behind" according to the projected
Tx time for next flow waiting in the Qdisc. Because we consider anything
within the offload window to be okay for fastpath we must consider
the entire offload window as "now".

Qdisc config:

qdisc fq 8001: dev eth0 parent 1234:1 limit 10000p flow_limit 100p \
  buckets 32768 orphan_mask 1023 bands 3 \
  priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 \
  weights 589824 196608 65536 quantum 3028b initial_quantum 15140b \
  low_rate_threshold 550Kbit \
  refill_delay 40ms timer_slack 10us horizon 10s horizon_drop

For iperf this change seems to do fine, the reordering is gone.
The fastpath still gets used most of the time:

  gc 0 highprio 0 fastpath 142614 throttled 418309 latency 19.1us
   xx_behind 2731

where "xx_behind" counts how many times we hit the new "return false".

Subject: [PATCH 2845/2948] ipmr: add debug check for mr table cleanup

The multicast route tables lifecycle, for both ipv4 and ipv6, is
protected by RCU using the RTNL lock for write access. In many
places a table pointer escapes the RCU (or RTNL) protected critical
section, but such scenarios are actually safe because tables are
deleted only at namespace cleanup time or just after allocation, in
case of default rule creation failure.

Tables freed at namespace cleanup time are assured to be alive for the
whole netns lifetime; tables freed just after creation time are never
exposed to other possible users.

Ensure that the free conditions are respected in ip{,6}mr_free_table, to
document the locking schema and to prevent future possible introduction
of 'table del' operation from breaking it.

Subject: [PATCH 2846/2948] ip6mr: fix tables suspicious RCU usage

Several places call ip6mr_get_table() with no RCU nor RTNL lock.
Add RCU protection inside such helper and provide a lockless variant
for the few callers that already acquired the relevant lock.

Note that some users additionally reference the table outside the RCU
lock. That is actually safe as the table deletion can happen only
after all table accesses are completed.

Fixes: e2d57766e674 ("net: Provide compat support for SIOCGETMIFCNT_IN6 and SIOCGETSGCNT_IN6.")

Subject: [PATCH 2847/2948] ipmr: fix tables suspicious RCU usage

Similar to the previous patch, plumb the RCU lock inside
the ipmr_get_table(), provided a lockless variant and apply
the latter in the few spots were the lock is already held.

Fixes: 709b46e8d90b ("net: Add compat ioctl support for the ipv4 multicast ioctl SIOCGETSGCNT")
Fixes: f0ad0860d01e ("ipv4: ipmr: support multiple tables")

Subject: [PATCH 2848/2948] ntp: Remove invalid cast in time offset math

Due to an unsigned cast, adjtimex() returns the wrong offest when using
ADJ_MICRO and the offset is negative. In this case a small negative offset
returns approximately 4.29 seconds (~ 2^32/1000 milliseconds) due to the
unsigned cast of the negative offset.

This cast was added when the kernel internal struct timex was changed to
use type long long for the time offset value to address the problem of a
64bit/32bit division on 32bit systems.

The correct cast would have been (s32), which is correct as time_offset can
only be in the range of [INT_MIN..INT_MAX] because the shift constant used
for calculating it is 32. But that's non-obvious.

Remove the cast and use div_s64() to cure the issue.

[ tglx: Fix white space damage, use div_s64() and amend the change log ]

Subject: [PATCH 2854/2948] s390/pci: Fix leak of struct zpci_dev when
 zpci_add_device() fails

Prior to commit 0467cdde8c43 ("s390/pci: Sort PCI functions prior to
creating virtual busses") the IOMMU was initialized and the device was
registered as part of zpci_create_device() with the struct zpci_dev
freed if either resulted in an error. With that commit this was moved
into a separate function called zpci_add_device().

While this new function logs when adding failed, it expects the caller
not to use and to free the struct zpci_dev on error. This difference
between it and zpci_create_device() was missed while changing the
callers and the incompletely initialized struct zpci_dev may get used in
zpci_scan_configured_device in the error path. This then leads to
a crash due to the device not being registered with the zbus. It was
also not freed in this case. Fix this by handling the error return of
zpci_add_device(). Since in this case the zdev was not added to the
zpci_list it can simply be discarded and freed. Also make this more
explicit by moving the kref_init() into zpci_add_device() and document
that zpci_zdev_get()/zpci_zdev_put() must be used after adding.

Subject: [PATCH 2855/2948] s390/pci: Fix potential double remove of hotplug
 slot

In commit 6ee600bfbe0f ("s390/pci: remove hotplug slot when releasing the
device") the zpci_exit_slot() was moved from zpci_device_reserved() to
zpci_release_device() with the intention of keeping the hotplug slot
around until the device is actually removed.

Now zpci_release_device() is only called once all references are
dropped. Since the zPCI subsystem only drops its reference once the
device is in the reserved state it follows that zpci_release_device()
must only deal with devices in the reserved state. Despite that it
contains code to tear down from both configured and standby state. For
the standby case this already includes the removal of the hotplug slot
so would cause a double removal if a device was ever removed in
either configured or standby state.

Instead of causing a potential double removal in a case that should
never happen explicitly WARN_ON() if a device in non-reserved state is
released and get rid of the dead code cases.

 Zenbook UM5606WA

This hardware has ALC294 codec with speaker NID 0x17 and bass speaker
NID 0x15.

This patch removes DAC NID 0x06 (without volume control) from
the connection list for bass speaker NID 0x15. Both speaker PINs
are routed to DAC NID 0x03 with this change.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since both Xe2 and Xe3 platforms currently use the same set of graphics
IP feature flags, we associate the "graphics_xe2" structure with both IPs.
Update the name string on that IP structure to clarify this and avoid
confusion as Xe3 platforms start going into public CI.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently in some testcases we can trigger:

[drm] *ERROR* GT0: SCHED_DONE: Unexpected engine state 0x02b1, guc_id=8, runnable_state=0
[drm] *ERROR* GT0: G2H action 0x1002 failed (-EPROTO) len 3 msg 02 10 00 90 08 00 00 00 00 00 00 00

Looking at a snippet of corresponding ftrace for this GuC id we can see:

498.852891: xe_sched_msg_add:     dev=0000:03:00.0, gt=0 guc_id=8, opcode=3

This looks to be the two scheduling_disable racing with each other, one
from the suspend (opcode=3) and then again during lr cleanup. While
those two operations are serialized, the G2H portion is not, therefore
when marking the queue as pending_disabled and then firing off the first
request, we proceed do the same again, however the first disable
response only fires after this which then clears the pending_disabled.
At this point the second comes back and is processed, however the
pending_disabled is no longer set, hence triggering the warning.

To fix this wait for pending_disabled when doing the lr cleanup and
calling disable_scheduling_deregister. Also do the same for all other
disable_scheduling callers.

It looks like we try to suspend the queue (opcode=3), setting
suspend_pending and triggering a disable_scheduling. The user then
closes the queue. However the close will also forcefully signal the
suspend fence after killing the queue, later when the G2H response for
disable_scheduling comes back we have now cleared suspend_pending when
signalling the suspend fence, so the disable_scheduling now incorrectly
tries to also deregister the queue. This leads to warnings since the queue
has yet to even be marked for destruction. We also seem to trigger
errors later with trying to double unregister the same queue.

To fix this tweak the ordering when handling the response to ensure we
don't race with a disable_scheduling that didn't actually intend to
perform an unregister.  The destruction path should now also correctly
wait for any pending_disable before marking as destroyed.

On some HW we want to avoid the host caching PTEs, since access from GPU
side can be incoherent. However here the special migrate object is
mapping PTEs which are written from the host and potentially cached. Use
XE_BO_FLAG_PAGETABLE to ensure that non-cached mapping is used, on
platforms where this matters.

Subject: [PATCH 2869/2948] cifs: support mounting with alternate password to
 allow password rotation

Fixes the case for example where the password specified on mount is a
recently expired password, but password2 is valid.  Without this patch
this mount scenario would fail.

This patch introduces the following changes to support password rotation on
mount:

1. If an existing session is not found and the new session setup results in
EACCES, EKEYEXPIRED or EKEYREVOKED, swap password and password2 (if
available), and retry the mount.

2. To match the new mount with an existing session, add conditions to check
if a) password and password2 of the new mount and the existing session are
the same, or b) password of the new mount is the same as the password2 of
the existing session, and password2 of the new mount is the same as the
password of the existing session.

3. If an existing session is found, but needs reconnect, retry the session
setup after swapping password and password2 (if available), in case the
previous attempt results in EACCES, EKEYEXPIRED or EKEYREVOKED.

Subject: [PATCH 2870/2948] cifs: during remount, make sure passwords are in
 sync

This fixes scenarios where remount can overwrite the only currently
working password, breaking reconnect.

We recently introduced a password2 field in both ses and ctx structs.
This was done so as to allow the client to rotate passwords for a mount
without any downtime. However, when the client transparently handles
password rotation, it can swap the values of the two password fields
in the ses struct, but not in smb3_fs_context struct that hangs off
cifs_sb. This can lead to a situation where a remount unintentionally
overwrites a working password in the ses struct.

In order to fix this, we first get the passwords in ctx struct
in-sync with ses struct, before replacing them with what the passwords
that could be passed as a part of remount.

Also, in order to avoid race condition between smb2_reconnect and
smb3_reconfigure, we make sure to lock session_mutex before changing
password and password2 fields of the ses structure.

Subject: [PATCH 2874/2948] nfs: ignore SB_RDONLY when mounting nfs

When exporting only one file system with fsid=0 on the server side, the
client alternately uses the ro/rw mount options to perform the mount
operation, and a new vfsmount is generated each time.

It can be reproduced as follows:
[root@localhost ~]# mount /dev/sda /mnt2
[root@localhost ~]# echo "/mnt2 *(rw,no_root_squash,fsid=0)" >/etc/exports
[root@localhost ~]# systemctl restart nfs-server
[root@localhost ~]# mount -t nfs -o ro,vers=4 127.0.0.1:/ /mnt/sdaa
[root@localhost ~]# mount -t nfs -o rw,vers=4 127.0.0.1:/ /mnt/sdaa
[root@localhost ~]# mount -t nfs -o ro,vers=4 127.0.0.1:/ /mnt/sdaa
[root@localhost ~]# mount -t nfs -o rw,vers=4 127.0.0.1:/ /mnt/sdaa
[root@localhost ~]# mount | grep nfs4
127.0.0.1:/ on /mnt/sdaa type nfs4 (ro,relatime,vers=4.2,rsize=1048576,...
127.0.0.1:/ on /mnt/sdaa type nfs4 (rw,relatime,vers=4.2,rsize=1048576,...
127.0.0.1:/ on /mnt/sdaa type nfs4 (ro,relatime,vers=4.2,rsize=1048576,...
127.0.0.1:/ on /mnt/sdaa type nfs4 (rw,relatime,vers=4.2,rsize=1048576,...
[root@localhost ~]#

We expected that after mounting with the ro option, using the rw option to
mount again would return EBUSY, but the actual situation was not the case.

As shown above, when mounting for the first time, a superblock with the ro
flag will be generated, and at the same time, in do_new_mount_fc -->
do_add_mount, it detects that the superblock corresponding to the current
target directory is inconsistent with the currently generated one
(path->mnt->mnt_sb != newmnt->mnt.mnt_sb), and a new vfsmount will be
generated.

When mounting with the rw option for the second time, since no matching
superblock can be found in the fs_supers list, a new superblock with the
rw flag will be generated again. The superblock in use (ro) is different
from the newly generated superblock (rw), and a new vfsmount will be
generated again.

When mounting with the ro option for the third time, the superblock (ro)
is found in fs_supers, the superblock in use (rw) is different from the
found superblock (ro), and a new vfsmount will be generated again.

We can switch between ro/rw through remount, and only one superblock needs
to be generated, thus avoiding the problem of repeated generation of
vfsmount caused by switching superblocks.

Furthermore, This can also resolve the issue described in the link.

Subject: [PATCH 2875/2948] sunrpc: clear XPRT_SOCK_UPD_TIMEOUT when reset
 transport

Since transport->sock has been set to NULL during reset transport,
XPRT_SOCK_UPD_TIMEOUT also needs to be cleared. Otherwise, the
xs_tcp_set_socket_timeouts() may be triggered in xs_tcp_send_request()
to dereference the transport->sock that has been set to NULL.

Subject: [PATCH 2876/2948] SUNRPC: timeout and cancel TLS handshake with
 -ETIMEDOUT

We've noticed a situation where an unstable TCP connection can cause the
TLS handshake to timeout waiting for userspace to complete it.  When this
happens, we don't want to return from xs_tls_handshake_sync() with zero, as
this will cause the upper xprt to be set CONNECTED, and subsequent attempts
to transmit will be returned with -EPIPE.  The sunrpc machine does not
recover from this situation and will spin attempting to transmit.

The return value of tls_handshake_cancel() can be used to detect a race
with completion:

 * tls_handshake_cancel - cancel a pending handshake
 * Return values:
 *   %true - Uncompleted handshake request was canceled
 *   %false - Handshake request already completed or not found

If true, we do not want the upper xprt to be connected, so return
-ETIMEDOUT.  If false, its possible the handshake request was lost and
that may be the reason for our timeout.  Again we do not want the upper
xprt to be connected, so return -ETIMEDOUT.

Ensure that we alway return an error from xs_tls_handshake_sync() if we
call tls_handshake_cancel().

Reproduction script:

mkdir -p /mnt/nfsshare
mkdir -p /mnt/nfs/netns_1
mkfs.ext4 /dev/sdb
mount /dev/sdb /mnt/nfsshare
systemctl restart nfs-server
chmod 777 /mnt/nfsshare
exportfs -i -o rw,no_root_squash *:/mnt/nfsshare

ip netns add netns_1
ip link add name veth_1_peer type veth peer veth_1
ifconfig veth_1_peer 11.11.0.254 up
ip link set veth_1 netns netns_1
ip netns exec netns_1 ifconfig veth_1 11.11.0.1

ip netns exec netns_1 /root/iptables -A OUTPUT -d 11.11.0.254 -p tcp \
	--tcp-flags FIN FIN  -j DROP

(note: In my environment, a DESTROY_CLIENTID operation is always sent
 immediately, breaking the nfs tcp connection.)
ip netns exec netns_1 timeout -s 9 300 mount -t nfs -o proto=tcp,vers=4.1 \
	11.11.0.254:/mnt/nfsshare /mnt/nfs/netns_1

ip netns del netns_1

The reason here is that the tcp socket in netns_1 (nfs side) has been
shutdown and closed (done in xs_destroy), but the FIN message (with ack)
is discarded, and the nfsd side keeps sending retransmission messages.
As a result, when the tcp sock in netns_1 processes the received message,
it sends the message (FIN message) in the sending queue, and the tcp timer
is re-established. When the network namespace is deleted, the net structure
accessed by tcp's timer handler function causes problems.

To fix this problem, let's hold netns refcnt for the tcp kernel socket as
done in other modules. This is an ugly hack which can easily be backported
to earlier kernels. A proper fix which cleans up the interfaces will
follow, but may not be so easy to backport.

Subject: [PATCH 2878/2948] nfs/blocklayout: Don't attempt unregister for
 invalid block device

Since commit d869da91cccb ("nfs/blocklayout: Fix premature PR key
unregistration") an unmount of a pNFS SCSI layout-enabled NFS may
dereference a NULL block_device in:

  bl_unregister_scsi+0x16/0xe0 [blocklayoutdriver]
  bl_free_device+0x70/0x80 [blocklayoutdriver]
  bl_free_deviceid_node+0x12/0x30 [blocklayoutdriver]

  nfs4_deviceid_purge_client+0x132/0x190 [nfsv4]
  unset_pnfs_layoutdriver+0x59/0x60 [nfsv4]
  nfs4_destroy_server+0x36/0x70 [nfsv4]
  nfs_free_server+0x23/0xe0 [nfs]
  deactivate_locked_super+0x30/0xb0
  cleanup_mnt+0xba/0x150
  task_work_run+0x59/0x90
  syscall_exit_to_user_mode+0x217/0x220
  do_syscall_64+0x8e/0x160

This happens because even though we were able to create the
nfs4_deviceid_node, the lookup for the device was unable to attach the
block device to the pnfs_block_dev.

If we never found a block device to register, we can avoid this case with
the PNFS_BDEV_REGISTERED flag.  Move the deref behind the test for the
flag.

Subject: [PATCH 2879/2948] nfs/blocklayout: Limit repeat device registration
 on failure

Every pNFS SCSI IO wants to do LAYOUTGET, then within the layout find the
device which can drive GETDEVINFO, then finally may need to prep the device
with a reservation.  This slow work makes a mess of IO latencies if one of
the later steps is going to fail for awhile.

If we're unable to register a SCSI device, ensure we mark the device as
unavailable so that it will timeout and be re-added via GETDEVINFO.  This
avoids repeated doomed attempts to register a device in the IO path.

Add some clarifying comments as well.

The current arrangement will have the test modules rebuilt on
any make without having the script or code actually change.
Take Masahiro Yamada's suggested fix and cleanups on the Makefile
to fix this.

  ==================================================================

Further analyzing the trace and the crash dump's vmcore file shows that
the wake_up() call in btrfs_encoded_read_endio() is calling wake_up() on
the wait_queue that is in the private data passed to the end_io handler.

Commit 4ff47df40447 ("btrfs: move priv off stack in
btrfs_encoded_read_regular_fill_pages()") moved 'struct
btrfs_encoded_read_private' off the stack.

Before that commit one can see a corruption of the private data when
analyzing the vmcore after a crash:

*(struct btrfs_encoded_read_private *)0xffff88815626eec8 = {
	.wait = (wait_queue_head_t){
		.lock = (spinlock_t){
			.rlock = (struct raw_spinlock){
				.raw_lock = (arch_spinlock_t){
					.val = (atomic_t){
						.counter = (int)-2005885696,
					},
					.locked = (u8)0,
					.pending = (u8)157,
					.locked_pending = (u16)40192,
					.tail = (u16)34928,
				},
				.magic = (unsigned int)536325682,
				.owner_cpu = (unsigned int)29,
				.owner = (void *)__SCT__tp_func_btrfs_transaction_commit+0x0 = 0x0,
				.dep_map = (struct lockdep_map){
					.key = (struct lock_class_key *)0xffff8881575a3b6c,
					.class_cache = (struct lock_class *[2]){ 0xffff8882a71985c0, 0xffffea00066f5d40 },
					.name = (const char *)0xffff88815626f100 = "",
					.wait_type_outer = (u8)37,
					.wait_type_inner = (u8)178,
					.lock_type = (u8)154,
				},
			},
			.__padding = (u8 [24]){ 0, 157, 112, 136, 50, 174, 247, 31, 29 },
			.dep_map = (struct lockdep_map){
				.key = (struct lock_class_key *)0xffff8881575a3b6c,
				.class_cache = (struct lock_class *[2]){ 0xffff8882a71985c0, 0xffffea00066f5d40 },
				.name = (const char *)0xffff88815626f100 = "",
				.wait_type_outer = (u8)37,
				.wait_type_inner = (u8)178,
				.lock_type = (u8)154,
			},
		},
		.head = (struct list_head){
			.next = (struct list_head *)0x112cca,
			.prev = (struct list_head *)0x47,
		},
	},
	.pending = (atomic_t){
		.counter = (int)-1491499288,
	},
	.status = (blk_status_t)130,
}

Here we can see several indicators of in-memory data corruption, e.g. the
large negative atomic values of ->pending or
->wait->lock->rlock->raw_lock->val, as well as the bogus spinlock magic
0x1ff7ae32 (decimal 536325682 above) instead of 0xdead4ead or the bogus
pointer values for ->wait->head.

To fix this, change atomic_dec_return() to atomic_dec_and_test() to fix the
corruption, as atomic_dec_return() is defined as two instructions on
x86_64, whereas atomic_dec_and_test() is defined as a single atomic
operation. This can lead to a situation where counter value is already
decremented but the if statement in btrfs_encoded_read_endio() is not
completely processed, i.e. the 0 test has not completed. If another thread
continues executing btrfs_encoded_read_regular_fill_pages() the
atomic_dec_return() there can see an already updated ->pending counter and
continues by freeing the private data. Continuing in the endio handler the
test for 0 succeeds and the wait_queue is woken up, resulting in a
use-after-free.

Subject: [PATCH 2885/2948] btrfs: fix deadlock between transaction commits and
 extent locks

When running a workload with fsstress and duperemove (generic/561) we can
hit a deadlock related to transaction commits and locking extent ranges,
as described below.

Task A hanging during a transaction commit, waiting for all other writers
to complete:

Which corresponds to line 2361 of transaction.c:

The transaction is in the TRANS_STATE_COMMIT_DOING state and so it's
waiting for all other existing writers to complete and release their
transaction handle.

Task B is running ordered extent completion and blocked waiting to lock an

This extent range locking happens after joining the current transaction,
so task A is waiting for task B to release its transaction handle
(decrementing the transaction's num_writers counter).

Task C while doing a fiemap it tries to join the current transaction:

It tries to join the current transaction, but it can't because the
transaction is in the TRANS_STATE_COMMIT_DOING state, so
join_transaction() returns -EBUSY to start_transaction() and makes it
wait for the current transaction to complete. And while it's waiting
for the transaction to complete, it's holding an extent range locked
in the same inode that task B is operating, which causes a deadlock
between these 3 tasks. The extent range for the inode was locked at
the start of the fiemap operation, early at extent_fiemap().

In short these tasks deadlock because:

1) Task A is waiting for task B to release its transaction handle;

2) Task B is waiting to lock an extent range for an inode while holding a
   transaction handle open;

3) Task C is waiting for the current transaction to complete (for task A
   to finish the transaction commit) while holding the extent range for
   the inode locked, so task B can't progress and release its transaction
   handle.

This results in an ABBA deadlock involving transaction commits and extent
locks. Extent locks are higher level locks, like inode VFS locks, and
should always be acquired before joining or starting a transaction, but
recently commit 2206265f41e9 ("btrfs: remove code duplication in ordered
extent finishing") accidentally changed btrfs_finish_one_ordered() to do
the transaction join before locking the extent range.

Fix this by making sure that btrfs_finish_one_ordered() always locks the
extent before joining a transaction and add an explicit comment about the
need for this order.

We are advertising experimental features through sysfs if
CONFIG_BTRFS_DEBUG is set, without looking if CONFIG_BTRFS_EXPERIMENTAL
is set. This is wrong as it will result in reporting experimental
features as supported when CONFIG_BTRFS_EXPERIMENTAL is not set but
CONFIG_BTRFS_DEBUG is set.

Fix this by checking for CONFIG_BTRFS_EXPERIMENTAL instead of
CONFIG_BTRFS_DEBUG.

Subject: [PATCH 2890/2948] posix-timers: Target group sigqueue to current task
 only if not exiting

A sigqueue belonging to a posix timer, which target is not a specific
thread but a whole thread group, is preferrably targeted to the current
task if it is part of that thread group.

However nothing prevents a posix timer event from queueing such a
sigqueue from a reaped yet running task. The interruptible code space
between exit_notify() and the final call to schedule() is enough for
posix_timer_fn() hrtimer to fire.

If that happens while the current task is part of the thread group
target, it is proposed to handle it but since its sighand pointer may
have been cleared already, the sigqueue is dropped even if there are
other tasks running within the group that could handle it.

As a result posix timers with thread group wide target may miss signals
when some of their threads are exiting.

Fix this with verifying that the current task hasn't been through
exit_notify() before proposing it as a preferred target so as to ensure
that its sighand is still here and stable.

complete_signal() might still reconsider the choice and find a better
target within the group if current has passed retarget_shared_pending()
already.

Subject: [PATCH 2891/2948] Revert "s390/mm: Allow large pages for KASAN shadow
 mapping"

This reverts commit ff123eb7741638d55abf82fac090bb3a543c1e74.

Allowing large pages for KASAN shadow mappings isn't inherently wrong,
but adding POPULATE_KASAN_MAP_SHADOW to large_allowed() exposes an issue
in can_large_pud() and can_large_pmd().

Since commit d8073dc6bc04 ("s390/mm: Allow large pages only for aligned
physical addresses"), both can_large_pud() and can_large_pmd() call _pa()
to check if large page physical addresses are aligned. However, _pa()
has a side effect: it allocates memory in POPULATE_KASAN_MAP_SHADOW
mode. This results in massive memory leaks.

The proper fix would be to address both large_allowed() and _pa()'s side
effects, but for now, revert this change to avoid the leaks.

Subject: [PATCH 2892/2948] io_uring/tctx: work around xa_store() allocation
 error issue

syzbot triggered the following WARN_ON:

WARNING: CPU: 0 PID: 16 at io_uring/tctx.c:51 __io_uring_free+0xfa/0x140 io_uring/tctx.c:51

which is the

WARN_ON_ONCE(!xa_empty(&tctx->xa));

sanity check in __io_uring_free() when a io_uring_task is going through
its final put. The syzbot test case includes injecting memory allocation
failures, and it very much looks like xa_store() can fail one of its
memory allocations and end up with ->head being non-NULL even though no
entries exist in the xarray.

Until this issue gets sorted out, work around it by attempting to
iterate entries in our xarray, and WARN_ON_ONCE() if one is found.

Subject: [PATCH 2893/2948] block, bfq: fix bfqq uaf in bfq_limit_depth()

Set new allocated bfqq to bic or remove freed bfqq from bic are both
protected by bfqd->lock, however bfq_limit_depth() is deferencing bfqq
from bic without the lock, this can lead to UAF if the io_context is
shared by multiple tasks.

For example, test bfq with io_uring can trigger following UAF in v6.6:

When checking for delayed refs when verifying if there are cross
references for a data extent, we stop if the path has nowait set and we
can't try lock the delayed ref head's mutex, returning -EAGAIN with the
goal of making a write fallback to a blocking context. However we ignore
the -EAGAIN at btrfs_cross_ref_exist() when check_delayed_ref() returns
it, and keep looping instead of immediately returning the -EAGAIN to the
caller.

Fix this by not looping if we get -EAGAIN and we have a nowait path.

Syzbot reports a null-ptr-deref in btrfs_search_slot().

The reproducer is using rescue=ibadroots, and the extent tree root is
corrupted thus the extent tree is NULL.

When scrub tries to search the extent tree to gather the needed extent
info, btrfs_search_slot() doesn't check if the target root is NULL or
not, resulting the null-ptr-deref.

Add sanity check for btrfs root before using it in btrfs_search_slot().

Subject: [PATCH 2897/2948] btrfs: ref-verify: fix use-after-free after invalid
 ref action

At btrfs_ref_tree_mod() after we successfully inserted the new ref entry
(local variable 'ref') into the respective block entry's rbtree (local
variable 'be'), if we find an unexpected action of BTRFS_DROP_DELAYED_REF,
we error out and free the ref entry without removing it from the block
entry's rbtree. Then in the error path of btrfs_ref_tree_mod() we call
btrfs_free_ref_cache(), which iterates over all block entries and then
calls free_block_entry() for each one, and there we will trigger a
use-after-free when we are called against the block entry to which we
added the freed ref entry to its rbtree, since the rbtree still points
to the block entry, as we didn't remove it from the rbtree before freeing
it in the error path at btrfs_ref_tree_mod(). Fix this by removing the
new ref entry from the rbtree before freeing it.

Syzbot report this with the following stack traces:

Subject: [PATCH 2898/2948] btrfs: fix lockdep warnings on io_uring encoded
 reads

Lockdep doesn't like the fact that btrfs_uring_read_extent() returns to
userspace still holding the inode lock, even though we release it once
the I/O finishes. Add calls to rwsem_release() and rwsem_acquire_read() to
work round this.

Subject: [PATCH 2899/2948] sh: cpuinfo: Fix a warning for
 CONFIG_CPUMASK_OFFSTACK

When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are selected,
cpu_max_bits_warn() generates a runtime warning similar as below when
showing /proc/cpuinfo. Fix this by using nr_cpu_ids (the runtime limit)
instead of NR_CPUS to iterate CPUs.

To fix this, let's only add it to the list after everything has

Subject: [PATCH 2902/2948] PCI/pwrctrl: Unregister platform device only if one
 actually exists

If a PCI device has an associated device_node with power supplies,
pci_bus_add_device() creates platform devices for use by pwrctrl.  When the
PCI device is removed, pci_stop_dev() uses of_find_device_by_node() to
locate the related platform device, then unregisters it.

But when we remove a PCI device with no associated device node,
dev_of_node(dev) is NULL, and of_find_device_by_node(NULL) returns the
first device with "dev->of_node == NULL".  The result is that we (a)
mistakenly unregister a completely unrelated platform device, leading to
issues like the first trace below, and (b) dereference the NULL pointer
from dev_of_node() when clearing OF_POPULATED, as in the second trace.

Unregister a platform device only if there is one associated with this PCI
device.  This resolves issues seen when doing:

  # echo 1 > /sys/bus/pci/devices/.../remove

Sample issue from unregistering the wrong platform device:

Subject: [PATCH 2904/2948] tools/power turbostat: Fix column printing for PMT
 xtal_time counters

If the very first printed column was for a PMT counter of type xtal_time
we would misalign the column header, because we were always printing the
delimiter.

Subject: [PATCH 2905/2948] tools/power turbostat: Allow using cpu device in
 perf counters on hybrid platforms

Intel hybrid platforms expose different perf devices for P and E cores.
Instead of one, "/sys/bus/event_source/devices/cpu" device, there are
"/sys/bus/event_source/devices/{cpu_core,cpu_atom}".

This, however makes it more complicated for the user,
because most of the counters are available on both and had to be
handled manually.

This patch allows users to use "virtual" cpu device that is seemingly
translated to cpu_core and cpu_atom perf devices, depending on the type
of a CPU we are opening the counter for.

Subject: [PATCH 2906/2948] tools/power turbostat: Fix trailing '\n' parsing

parse_cpu_string() parses the string input either from command line or
from /sys/fs/cgroup/cpuset.cpus.effective to get a list of CPUs that
turbostat can run with.

The cpu string returned by /sys/fs/cgroup/cpuset.cpus.effective contains
a trailing '\n', but strtoul() fails to treat this as an error.

That says, for the code below
	val = ("\n", NULL, 10);
val returns 0, and errno is also not set.

As a result, CPU0 is erroneously considered as allowed CPU and this
causes failures when turbostat tries to run on CPU0.

 get_counters: Could not migrate to CPU 0
 ...
 turbostat: re-initialized with num_cpus 8, allowed_cpus 5
 get_counters: Could not migrate to CPU 0

Add a check to return immediately if '\n' or '\0' is detected.

Honoring these flags makes it easier for several programs

Subject: [PATCH 2913/2948] tools/power turbostat: Enhance platform divergence
 description

In various generations, platforms often share a majority of features,
diverging only in a few specific aspects. The current approach of using
hardcoded values in 'platform_features' structure fails to effectively
represent these divergences.

To improve the description of platform divergence:
1. Each newly introduced 'platform_features' structure must have a base,
   typically derived from the previous generation.
2. Platform feature values should be inherited from the base structure
   rather than being hardcoded.
This approach ensures a more accurate and maintainable representation of
platform-specific features across different generations.

Converts `adl_features` and `lnl_features` to follow this new scheme.

No functional change.

Subject: [PATCH 2915/2948] tools/power turbostat: Consolidate graphics sysfs
 access

Currently, there is an inconsistency in how graphics sysfs knobs are
accessed: graphics residency sysfs knobs are opened and closed for each
read, while graphics frequency sysfs knobs are opened once and remain
open until turbostat exits. This inconsistency is confusing and adds
unnecessary code complexity.

Consolidate the access method by opening the sysfs files once and
reusing the file pointers for subsequent accesses. This approach
simplifies the code and ensures a consistent method for accessing
graphics sysfs knobs.

Subject: [PATCH 2916/2948] tools/power turbostat: Cache graphics sysfs file
 descriptors during probe

Snapshots of the graphics sysfs knobs are taken based on file
descriptors. To optimize this process, open the files and cache the file
descriptors during the graphics probe phase. As a result, the previously
cached pathnames become redundant and are removed.

This change aims to streamline the code without altering its functionality.

No functional change intended.

Subject: [PATCH 2917/2948] tools/power turbostat: Add support for
 /sys/class/drm/card1

On some machines, the graphics device is enumerated as
/sys/class/drm/card1 instead of /sys/class/drm/card0. The current
implementation does not handle this scenario, resulting in the loss of
graphics C6 residency and frequency information.

Add support for /sys/class/drm/card1, ensuring that turbostat can
retrieve and display the graphics columns for these platforms.

Subject: [PATCH 2918/2948] tools/power turbostat: Force --no-perf in --dump
 mode

Force the --no-perf early to prevent using it as a source. User asks for
raw values, but perf returns them relative to the opening of the file
descriptor.

Subject: [PATCH 2919/2948] tools/power turbostat: Fix child's argument
 forwarding

Add '+' to optstring when early scanning for --no-msr and --no-perf.
It causes option processing to stop as soon as a nonoption argument is
encountered, effectively skipping child's arguments.

Fixes: 3e4048466c39 ("tools/power turbostat: Add --no-msr option")

Subject: [PATCH 2920/2948] tools/power turbostat: Add RAPL psys as a built-in
 counter

Introduce the counter as a part of global, platform counters structure.
We open the counter for only one cpu, but otherwise treat it as an
ordinary RAPL counter, allowing for grouped perf read.

The counter is disabled by default, because it's interpretation may
require additional, platform specific information, making it unsuitable
for general use.

bprintf() is unused. Remove it. It was added in the commit 4370aa4aa753
("vsprintf: add binary printf") but as far as I can see was never used,
unlike the other two functions in that patch.

Subject: [PATCH 2923/2948] strscpy: write destination buffer only once

The point behind strscpy() was to once and for all avoid all the
problems with 'strncpy()' and later broken "fixed" versions like
strlcpy() that just made things worse.

So strscpy not only guarantees NUL-termination (unlike strncpy), it also
doesn't do unnecessary padding at the destination.  But at the same time
also avoids byte-at-a-time reads and writes by _allowing_ some extra NUL
writes - within the size, of course - so that the whole copy can be done
with word operations.

It is also stable in the face of a mutable source string: it explicitly
does not read the source buffer multiple times (so an implementation
using "strnlen()+memcpy()" would be wrong), and does not read the source
buffer past the size (like the mis-design that is strlcpy does).

Finally, the return value is designed to be simple and unambiguous: if
the string cannot be copied fully, it returns an actual negative error,
making error handling clearer and simpler (and the caller already knows
the size of the buffer).  Otherwise it returns the string length of the
result.

However, there was one final stability issue that can be important to
callers: the stability of the destination buffer.

In particular, the same way we shouldn't read the source buffer more
than once, we should avoid doing multiple writes to the destination
buffer: first writing a potentially non-terminated string, and then
terminating it with NUL at the end does not result in a stable result
buffer.

Yes, it gives the right result in the end, but if the rule for the
destination buffer was that it is _always_ NUL-terminated even when
accessed concurrently with updates, the final byte of the buffer needs
to always _stay_ as a NUL byte.

[ Note that "final byte is NUL" here is literally about the final byte
  in the destination array, not the terminating NUL at the end of the
  string itself. There is no attempt to try to make concurrent reads and
  writes give any kind of consistent string length or contents, but we
  do want to guarantee that there is always at least that final
  terminating NUL character at the end of the destination array if it
  existed before ]

This is relevant in the kernel for the tsk->comm[] array, for example.
Even without locking (for either readers or writers), we want to know
that while the buffer contents may be garbled, it is always a valid C
string and always has a NUL character at 'comm[TASK_COMM_LEN-1]' (and
never has any "out of thin air" data).

So avoid any "copy possibly non-terminated string, and terminate later"
behavior, and write the destination buffer only once.

Subject: [PATCH 2925/2948] Get rid of 'remove_new' relic from platform driver
 struct

The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.

Subject: [PATCH 2926/2948] LoongArch: Fix reserving screen info memory for
 above-4G firmware

Since screen_info.lfb_base is a __u32 type, an above-4G address need an
ext_lfb_base to present its higher 32bits. In init_screen_info() we can
use __screen_info_lfb_base() to handle this case for reserving screen
info memory.

Subject: [PATCH 2927/2948] LoongArch/irq: Use seq_put_decimal_ull_width() for
 decimal values

Performance improvement for reading /proc/interrupts on LoongArch.

On a system with n CPUs and m interrupts, there will be n*m decimal
values yielded via seq_printf(.."%10u "..) which is less efficient than
seq_put_decimal_ull_width(), stress reading /proc/interrupts indicates
~30% performance improvement with this patch (and its friends).

 BUG: non-zero pgtables_bytes on freeing mm: -16384

On LoongArch system, invalid huge pte entry should be invalid_pte_table
or a single _PAGE_HUGE bit rather than a zero value. And it should be
the same with invalid pmd entry, since pmd_none() is called by function
free_pgd_range() and pmd_none() return 0 by huge_pte_clear(). So single
_PAGE_HUGE bit is also treated as a valid pte table and free_pte_range()
will be called in free_pmd_range().

  free_pmd_range()
        pmd = pmd_offset(pud, addr);
        do {

Here invalid_pte_table is used for both invalid huge pte entry and

Subject: [PATCH 2929/2948] LoongArch: BPF: Adjust the parameter of emit_jirl()

The branch instructions beq, bne, blt, bge, bltu, bgeu and jirl belong
to the format reg2i16, but the sequence of oprand is different for the
instruction jirl. So adjust the parameter order of emit_jirl() to make
it more readable correspond with the Instruction Set Architecture manual.

Here are the instruction formats:

  beq     rj, rd, offs16
  bne     rj, rd, offs16
  blt     rj, rd, offs16
  bge     rj, rd, offs16
  bltu    rj, rd, offs16
  bgeu    rj, rd, offs16
  jirl    rd, rj, offs16

On some machines like the ASUS Vivobook S14 writing the thermal policy
returns the currently writen thermal policy instead of an error code.

Ignore the return code to avoid falsely returning an error when the
thermal policy was written successfully.

Fix it by protecting kvm_io_bus_{read,write}() with SRCU.

Subject: [PATCH 2936/2948] scripts/nsdeps: get 'make nsdeps' working again

Since commit cdd30ebb1b9f ("module: Convert symbol namespace to string
literal"), when MODULE_IMPORT_NS() is missing, 'make nsdeps' inserts
pointless code:

    MODULE_IMPORT_NS("ns");

Here, "ns" is not a namespace, but the variable in the semantic patch.
It must not be quoted. Instead, a string literal must be passed to
Coccinelle.

Fixes: cdd30ebb1b9f ("module: Convert symbol namespace to string literal")

 MODULE_IMPORT_NS()

This reverts the misconversions introduced by commit cdd30ebb1b9f
("module: Convert symbol namespace to string literal").

The affected descriptions refer to MODULE_IMPORT_NS() tags in general,
rather than suggesting the use of the empty string ("") as the
namespace.

 literal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit cdd30ebb1b9f ("module: Convert symbol namespace to string
literal") only converted MODULE_IMPORT_NS() and EXPORT_SYMBOL_NS(),
leaving DEFAULT_SYMBOL_NAMESPACE as a macro expansion.

This commit converts DEFAULT_SYMBOL_NAMESPACE in the same way to avoid
annoyance for the default namespace as well.
