Documentation: KUnit: reword description of assertions
The existing wording implies that kunit_kmalloc_array() is "the method
under test". We're actually testing the sort() function in that example.
This is because the example was changed in commit

Documentation: KUnit: make usage.rst a superset of tips.rst, remove duplication
usage.rst had most of the content of the tips.rst page copied over. But it's missing https://www.kernel.org/doc/html/v6.0/dev-tools/kunit/tips.html#customizing-error-messages Copy it over so we can retire tips.rst w/o losing content. And in that process, it also gained a duplicate section about how KUNIT_ASSERT_*() exit the test case early. Remove that.

kunit: eliminate KUNIT_INIT_*_ASSERT_STRUCT macros
These macros exist because passing an initializer list to other macros
is hard.
The goal of these macros is to generate a line like
struct $ASSERT_TYPE __assertion = $APPROPRIATE_INITIALIZER;
e.g.
struct kunit_unary_assertion __assertion = {
.condition = "foo()",
.expected_true = true
};
But the challenge is you can't pass `{.condition=..., .expect_true=...}`
as a macro argument, since the comma means you're actually passing two
arguments, `{.condition=...` and `.expect_true=....}`.
So we'd made custom macros for each different initializer-list shape.
But we can work around this with the following generic macro
#define KUNIT_INIT_ASSERT(initializers...) { initializers }
Note: this has the downside that we have to rename some macros arguments
to not conflict with the struct field names (e.g. `expected_true`).
It's a bit gross, but probably worth reducing the # of macros.

Updates for miscellaneous x86 areas:
- Reserve a new boot loader type for barebox which is usally used on ARM
and MIPS, but can also be utilized as EFI payload on x86 to provide
watchdog-supervised boot up.
- Consolidate the native and compat 32bit signal handling code and split
the 64bit version out into a separate source file
- Switch the ESPFIX random usage to get_random_long().

Updates for timers, timekeeping and drivers:
- Core:
- The timer_shutdown[_sync]() infrastructure:
Tearing down timers can be tedious when there are circular
dependencies to other things which need to be torn down. A prime
example is timer and workqueue where the timer schedules work and the
work arms the timer.
What needs to prevented is that pending work which is drained via
destroy_workqueue() does not rearm the previously shutdown
timer. Nothing in that shutdown sequence relies on the timer being
functional.
The conclusion was that the semantics of timer_shutdown_sync() should
be:
- timer is not enqueued
- timer callback is not running
- timer cannot be rearmed
Preventing the rearming of shutdown timers is done by discarding rearm
attempts silently. A warning for the case that a rearm attempt of a
shutdown timer is detected would not be really helpful because it's
entirely unclear how it should be acted upon. The only way to address
such a case is to add 'if (in_shutdown)' conditionals all over the
place. This is error prone and in most cases of teardown not required
all.
- The real fix for the bluetooth HCI teardown based on
timer_shutdown_sync().
A larger scale conversion to timer_shutdown_sync() is work in
progress.
- Consolidation of VDSO time namespace helper functions
- Small fixes for timer and timerqueue
- Drivers:
- Prevent integer overflow on the XGene-1 TVAL register which causes
an never ending interrupt storm.
- The usual set of new device tree bindings
- Small fixes and improvements all over the place

A set of changes for the x86 APIC code:
- Handle the case where x2APIC is enabled and locked by the BIOS on a

does not make it to the graphical console during very early boot,
simply disable the local APIC completely and boot with the PIC and very
limited functionality, which allows to diagnose the issue.
- Convert x86 APIC device tree bindings to YAML
- Extend x86 APIC device tree bindings to configure interrupt delivery
mode and handle this in during init. This allows to boot with device
tree on platforms which lack a legacy PIC.

Updates for the interrupt core and driver subsystem:
- Core:
The bulk is the rework of the MSI subsystem to support per device MSI
interrupt domains. This solves conceptual problems of the current
PCI/MSI design which are in the way of providing support for PCI/MSI[-X]
and the upcoming PCI/IMS mechanism on the same device.
IMS (Interrupt Message Store] is a new specification which allows device
manufactures to provide implementation defined storage for MSI messages
contrary to the uniform and specification defined storage mechanisms for
PCI/MSI and PCI/MSI-X. IMS not only allows to overcome the size limitations
of the MSI-X table, but also gives the device manufacturer the freedom to
store the message in arbitrary places, even in host memory which is shared
with the device.
There have been several attempts to glue this into the current MSI code,
but after lengthy discussions it turned out that there is a fundamental
design problem in the current PCI/MSI-X implementation. This needs some
historical background.
When PCI/MSI[-X] support was added around 2003, interrupt management was
completely different from what we have today in the actively developed
architectures. Interrupt management was completely architecture specific
and while there were attempts to create common infrastructure the
commonalities were rudimentary and just providing shared data structures and
interfaces so that drivers could be written in an architecture agnostic
way.
The initial PCI/MSI[-X] support obviously plugged into this model which
resulted in some basic shared infrastructure in the PCI core code for
setting up MSI descriptors, which are a pure software construct for holding
data relevant for a particular MSI interrupt, but the actual association to
Linux interrupts was completely architecture specific. This model is still
supported today to keep museum architectures and notorious stranglers
alive.
In 2013 Intel tried to add support for hot-pluggable IO/APICs to the kernel,
which was creating yet another architecture specific mechanism and resulted
in an unholy mess on top of the existing horrors of x86 interrupt handling.
The x86 interrupt management code was already an incomprehensible maze of
indirections between the CPU vector management, interrupt remapping and the
actual IO/APIC and PCI/MSI[-X] implementation.
At roughly the same time ARM struggled with the ever growing SoC specific
extensions which were glued on top of the architected GIC interrupt
controller.
This resulted in a fundamental redesign of interrupt management and
provided the today prevailing concept of hierarchical interrupt
domains. This allowed to disentangle the interactions between x86 vector
domain and interrupt remapping and also allowed ARM to handle the zoo of
SoC specific interrupt components in a sane way.
The concept of hierarchical interrupt domains aims to encapsulate the
functionality of particular IP blocks which are involved in interrupt
delivery so that they become extensible and pluggable. The X86
encapsulation looks like this:
|--- device 1
[Vector]---[Remapping]---[PCI/MSI]--|...
|--- device N
where the remapping domain is an optional component and in case that it is
not available the PCI/MSI[-X] domains have the vector domain as their
parent. This reduced the required interaction between the domains pretty
much to the initialization phase where it is obviously required to
establish the proper parent relation ship in the components of the
hierarchy.
While in most cases the model is strictly representing the chain of IP
blocks and abstracting them so they can be plugged together to form a
hierarchy, the design stopped short on PCI/MSI[-X]. Looking at the hardware
it's clear that the actual PCI/MSI[-X] interrupt controller is not a global
entity, but strict a per PCI device entity.
Here we took a short cut on the hierarchical model and went for the easy
solution of providing "global" PCI/MSI domains which was possible because
the PCI/MSI[-X] handling is uniform across the devices. This also allowed
to keep the existing PCI/MSI[-X] infrastructure mostly unchanged which in
turn made it simple to keep the existing architecture specific management
alive.
A similar problem was created in the ARM world with support for IP block
specific message storage. Instead of going all the way to stack a IP block
specific domain on top of the generic MSI domain this ended in a construct
which provides a "global" platform MSI domain which allows overriding the
irq_write_msi_msg() callback per allocation.
In course of the lengthy discussions we identified other abuse of the MSI
infrastructure in wireless drivers, NTB etc. where support for
implementation specific message storage was just mindlessly glued into the
existing infrastructure. Some of this just works by chance on particular
platforms but will fail in hard to diagnose ways when the driver is used
on platforms where the underlying MSI interrupt management code does not
expect the creative abuse.
Another shortcoming of today's PCI/MSI-X support is the inability to
allocate or free individual vectors after the initial enablement of
MSI-X. This results in an works by chance implementation of VFIO (PCI
pass-through) where interrupts on the host side are not set up upfront to
avoid resource exhaustion. They are expanded at run-time when the guest
actually tries to use them. The way how this is implemented is that the
host disables MSI-X and then re-enables it with a larger number of
vectors again. That works by chance because most device drivers set up
all interrupts before the device actually will utilize them. But that's
not universally true because some drivers allocate a large enough number
of vectors but do not utilize them until it's actually required,
e.g. for acceleration support. But at that point other interrupts of the
device might be in active use and the MSI-X disable/enable dance can
just result in losing interrupts and therefore hard to diagnose subtle
problems.
Last but not least the "global" PCI/MSI-X domain approach prevents to
utilize PCI/MSI[-X] and PCI/IMS on the same device due to the fact that IMS
is not longer providing a uniform storage and configuration model.
The solution to this is to implement the missing step and switch from
global PCI/MSI domains to per device PCI/MSI domains. The resulting
hierarchy then looks like this:
|--- [PCI/MSI] device 1
[Vector]---[Remapping]---|...
|--- [PCI/MSI] device N
which in turn allows to provide support for multiple domains per device:
|--- [PCI/MSI] device 1
|--- [PCI/IMS] device 1
[Vector]---[Remapping]---|...
|--- [PCI/MSI] device N
|--- [PCI/IMS] device N
This work converts the MSI and PCI/MSI core and the x86 interrupt
domains to the new model, provides new interfaces for post-enable
allocation/free of MSI-X interrupts and the base framework for PCI/IMS.
PCI/IMS has been verified with the work in progress IDXD driver.
There is work in progress to convert ARM over which will replace the
platform MSI train-wreck. The cleanup of VFIO, NTB and other creative
"solutions" are in the works as well.

Pull irq updates from Thomas Gleixner:
"Updates for the interrupt core and driver subsystem:
The bulk is the rework of the MSI subsystem to support per device MSI
interrupt domains. This solves conceptual problems of the current
PCI/MSI design which are in the way of providing support for
PCI/MSI[-X] and the upcoming PCI/IMS mechanism on the same device.
IMS (Interrupt Message Store] is a new specification which allows
device manufactures to provide implementation defined storage for MSI
messages (as opposed to PCI/MSI and PCI/MSI-X that has a specified
message store which is uniform accross all devices). The PCI/MSI[-X]
uniformity allowed us to get away with "global" PCI/MSI domains.
IMS not only allows to overcome the size limitations of the MSI-X
table, but also gives the device manufacturer the freedom to store the
message in arbitrary places, even in host memory which is shared with
the device.
There have been several attempts to glue this into the current MSI
code, but after lengthy discussions it turned out that there is a
fundamental design problem in the current PCI/MSI-X implementation.
This needs some historical background.
When PCI/MSI[-X] support was added around 2003, interrupt management
was completely different from what we have today in the actively
developed architectures. Interrupt management was completely
architecture specific and while there were attempts to create common
infrastructure the commonalities were rudimentary and just providing
shared data structures and interfaces so that drivers could be written
in an architecture agnostic way.
The initial PCI/MSI[-X] support obviously plugged into this model
which resulted in some basic shared infrastructure in the PCI core
code for setting up MSI descriptors, which are a pure software
construct for holding data relevant for a particular MSI interrupt,
but the actual association to Linux interrupts was completely
architecture specific. This model is still supported today to keep
museum architectures and notorious stragglers alive.
In 2013 Intel tried to add support for hot-pluggable IO/APICs to the
kernel, which was creating yet another architecture specific mechanism
and resulted in an unholy mess on top of the existing horrors of x86
interrupt handling. The x86 interrupt management code was already an
incomprehensible maze of indirections between the CPU vector
management, interrupt remapping and the actual IO/APIC and PCI/MSI[-X]
implementation.
At roughly the same time ARM struggled with the ever growing SoC
specific extensions which were glued on top of the architected GIC
interrupt controller.
This resulted in a fundamental redesign of interrupt management and
provided the today prevailing concept of hierarchical interrupt
domains. This allowed to disentangle the interactions between x86
vector domain and interrupt remapping and also allowed ARM to handle
the zoo of SoC specific interrupt components in a sane way.
The concept of hierarchical interrupt domains aims to encapsulate the
functionality of particular IP blocks which are involved in interrupt
delivery so that they become extensible and pluggable. The X86
encapsulation looks like this:
|--- device 1
[Vector]---[Remapping]---[PCI/MSI]--|...
|--- device N
where the remapping domain is an optional component and in case that
it is not available the PCI/MSI[-X] domains have the vector domain as
their parent. This reduced the required interaction between the
domains pretty much to the initialization phase where it is obviously
required to establish the proper parent relation ship in the
components of the hierarchy.
While in most cases the model is strictly representing the chain of IP
blocks and abstracting them so they can be plugged together to form a
hierarchy, the design stopped short on PCI/MSI[-X]. Looking at the
hardware it's clear that the actual PCI/MSI[-X] interrupt controller
is not a global entity, but strict a per PCI device entity.
Here we took a short cut on the hierarchical model and went for the

because the PCI/MSI[-X] handling is uniform across the devices. This
also allowed to keep the existing PCI/MSI[-X] infrastructure mostly

block specific message storage. Instead of going all the way to stack
a IP block specific domain on top of the generic MSI domain this ended
in a construct which provides a "global" platform MSI domain which
allows overriding the irq_write_msi_msg() callback per allocation.
In course of the lengthy discussions we identified other abuse of the
MSI infrastructure in wireless drivers, NTB etc. where support for
implementation specific message storage was just mindlessly glued into
the existing infrastructure. Some of this just works by chance on
particular platforms but will fail in hard to diagnose ways when the
driver is used on platforms where the underlying MSI interrupt

Three small x86 fixes which did not make it into 6.1:
- Remove a superfluous noinline which prevents GCC-7.3 to optimize a stub
function away.
- Allow uprobes on REP NOP and do not treat them like word-sized branch
instructions.
- Make the VDSO symbol export of __vdso_sgx_enter_enclave() depend on
CONFIG_X86_SGX to prevent build fails with newer LLVM versions which
rightfully detect that there is no function behind the symbol.

s390 updates for 6.2 merge window
- Factor out handle_write() function and simplify 3215 console
write operation.
- When 3170 terminal emulator is connected to the 3215 console
driver the boot time could be very long due to limited buffer
space or missing operator input. Add con3215_drop command line
parameter and con3215_drop sysfs attribute file to instruct
the kernel drop console data when such conditions are met.
- Fix white space errors in 3215 console driver.
- Move enum paiext_mode definition to a header file and rename
it to paievt_mode to indicate this is now used for several
events. Rename PAI_MODE_COUNTER to PAI_MODE_COUNTING to make
consistent with PAI_MODE_SAMPLING.
- Simplify the logic of PMU pai_crypto mapped buffer reference
counter and make it consistent with PMU pai_ext.
- Rename PMU pai_crypto mapped buffer structure member users
to active_events to make it consistent with PMU pai_ext.
- Enable HUGETLB_PAGE_OPTIMIZE_VMEMMAP configuration option.
This results in saving of 12K per 1M hugetlb page (~1.2%)
and 32764K per 2G hugetlb page (~1.6%).
- Use generic serial.h, bugs.h, shmparam.h and vga.h header
files and scrap s390-specific versions.
- The generic percpu setup code does not expect the s390-like
implementation and emits a warning. To get rid of that warning
and provide sane CPU-to-node and CPU-to-CPU distance mappings
implementat a minimal version of setup_per_cpu_areas().
- Use kstrtobool() instead of strtobool() for re-IPL sysfs device
attributes.
- Avoid unnecessary lookup of a pointer to MSI descriptor when
setting IRQ affinity for a PCI device.
- Get rid of "an incompatible function type cast" warning by
changing debug_sprintf_format_fn() function prototype so it
matches the debug_format_proc_t function type.
- Remove unused info_blk_hdr__pcpus() and get_page_state()
functions.
- Get rid of clang "unused unused insn cache ops function"
warning by moving s390_insn definition to a private header.
- Get rid of clang "unused function" warning by making function
raw3270_state_final() only available if CONFIG_TN3270_CONSOLE
is enabled.
- Use kstrobool() to parse sclp_con_drop parameter to make it
identical to the con3215_drop parameter and allow passing
values like "yes" and "true".
- Use sysfs_emit() for all SCLP sysfs show functions, which is
the current standard way to generate output strings.
- Make SCLP con_drop sysfs attribute also writable and allow to
change its value during runtime. This makes SCLP console drop
handling consistent with the 3215 device driver.
- Virtual and physical addresses are indentical on s390. However,
there is still a confusion when pointers are directly casted to
physical addresses or vice versa. Use correct address converters
virt_to_phys() and phys_to_virt() for s390 channel IO drivers.
- Support for power managemant has been removed from s390 since
quite some time. Remove unused power managemant code from the
appldata device driver.
- Allow memory tools like KASAN see memory accesses from the
checksum code. Switch to GENERIC_CSUM if KASAN is enabled,
just like x86 does.
- Add support of ECKD DASDs disks so it could be used as boot
and dump devices.
- Follow checkpatch recommendations and use octal values instead
of S_IRUGO and S_IWUSR for dump device attributes in sysfs.
- Changes to vx-insn.h do not cause a recompile of C files that
use asm(".include \"asm/vx-insn.h\"\n") magic to access vector
instruction macros from inline assemblies. Add wrapper include
header file to avoid this problem.
- Use vector instruction macros instead of byte patterns to
increase register validation routine readability.
- The current machine check register validation handling does not
take into account various scenarios and might lead to killing a
wrong user process or potentially ignore corrupted FPU registers.
Simplify logic of the machine check handler and stop the whole
machine if the previous context was kerenel mode. If the previous
context was user mode, kill the current task.
- Introduce sclp_emergency_printk() function which can be used to
emit a message in emergency cases. It is supposed to be used in
cases where regular console device drivers may not work anymore,
e.g. unrecoverable machine checks.
Keep the early Service-Call Control Block so it can also be used
after initdata has been freed to allow sclp_emergency_printk()
implementation.
- In case a system will be stopped because of an unrecoverable
machine check error print the machine check interruption code
to give a hint of what went wrong.
- Move storage error checking from the assembly entry code to C
in order to simplify machine check handling. Enter the handler
with DAT turned on, which simplifies the entry code even more.
- The machine check extended save areas are allocated using
a private "nmi_save_areas" slab cache which guarantees a
required power-of-two alignment. Get rid of that cache in
favour of kmalloc().

- The current machine check register validation handling does not take
into account various scenarios and might lead to killing a wrong user
process or potentially ignore corrupted FPU registers. Simplify logic
of the machine check handler and stop the whole machine if the
previous context was kerenel mode. If the previous context was user
mode, kill the current task
- Introduce sclp_emergency_printk() function which can be used to emit
a message in emergency cases. It is supposed to be used in cases
where regular console device drivers may not work anymore, e.g.
unrecoverable machine checks
Keep the early Service-Call Control Block so it can also be used
after initdata has been freed to allow sclp_emergency_printk()
implementation
- In case a system will be stopped because of an unrecoverable machine
check error print the machine check interruption code to give a hint
of what went wrong
- Move storage error checking from the assembly entry code to C in
order to simplify machine check handling. Enter the handler with DAT
turned on, which simplifies the entry code even more
- The machine check extended save areas are allocated using a private
"nmi_save_areas" slab cache which guarantees a required power-of-two
alignment. Get rid of that cache in favour of kmalloc()

SoC: DT changes for 6.2
The devicetree changes contain exactly 1000 non-merge changesets,
including a number of new arm64 SoC variants from Qualcomm and Apple,
as well as the Renesas r9a07g043f/u chip in both arm64 and riscv variants
While we have occasionally merged support for non-arm SoCs in the past,
this is now the normal path for riscv devicetree files.
The most notable changes, by SoC platform, are:
- The Apple T6000 (M1 Pro), T6001 (M1 Max) and T6002 (M2 Ultra)
chips now have initial support. This is particularly nice as I am
typing this on a T6002 Mac Studio with only a small number of driver
patches.
- Qualcomm MSM8996 Pro (Snapdragon 821), SM6115 (Snapdragon 662), SM4250
(Snapdragon 460), SM6375 (Snapdragon 695), SDM670 (Snapdragon 670),
MSM8976 (Snapdragon 652) and MSM8956 (Snapdragon 650) are all mobile
phone chips that are closely related to others we already support.
Adding those helps support more phones and we add several models
from Sony (Xperia 10 IV, 5 IV, X, and X compact), OnePlus (One, 3,
3T, and Nord N100), Xiaomi (Poco F1, Mi6), Huawei (Watch) and Google
(Pixel 3a). There are also new variants of the Herobrine and Trogdor
chromebook motherboards. SA8540P is an automotive SoC used in the
Qdrive-3 development platform
- Rockchips gains no new SoC variants, but a lot of new boards:
three mobile gaming systems based on RK3326 Odroid-Go/rg351 family,
two more Anbernic gaming systems based on RK3566 and a number of
other RK356x based single-board computers.
- Renesas RZ/G2UL (r9a07g043) was already supported for arm64, but as
the newly added RZ/Five is based on the same design, this now gets
reorganized in order to share most of the dts description between
the two and add the RZ/Five SMARC EVK board support.
Aside from that, there are the usual changes all over the tree:
- New boards on other platforms contain two ASpeed BMC users, two
Broadcom based Wifi routers, Zyxel NSA310S NAS, the i.MX6 based Kobo
Aura2 ebook reader, two i.MX8 based development boards, two Uniphier
Pro5 development boards, the STM32MP1 testbench board from DHCOR,
the TI K3 based BeagleBone AI-64 board, and the Mediatek Helio X10
based Sony Xperia M5 phone.
- The Starfive JH7100 source gets reorganized in order to support the
VisionFive V1 board.
- Minor updates and cleanups for Intel SoCFPGA, Marvell PXA168,
TI, ST, NXP, Apple, Broadcom, Juno, Marvell MVEBU, at91, nuvoton,
Tegra, Mediatek, Renesas, Hisilicon, Allwinner, Samsung, ux500,
spear, ... The treewide cleanups now have a lot of fixes for cache
nodes and other binding violoations.
- Somewhat larger sets of reworks for NVIDIA Tegra, Qualcomm
and Renesas platforms, adding a lot more on-chip device support
- A rework of the way that DTB overlays are built.

SoC driver updates for 6.2
There are few major updates in the SoC specific drivers, mainly the usual
reworks and support for variants of the existing SoC. While this remains
Arm centric for the most part, the branch now also contains updates to
risc-v and loongarch specific code in drivers/soc/.
Notable changes include:
- Support for the newly added Qualcomm Snapdragon variants
(MSM8956, MSM8976, SM6115, SM4250, SM8150, SA8155 and SM8550) in the
soc ID, rpmh, rpm, spm and powerdomain drivers.
- Documentation for the somewhat controversial qcom,board-id
properties that are required for booting a number of machines
- A new SoC identification driver for the loongson-2 (loongarch)
platform
- memory controller updates for stm32, tegra, and renesas.
- a new DT binding to better describe LPDDR2/3/4/5 chips in
the memory controller subsystem
- Updates for Tegra specific drivers across multiple subsystems,
improving support for newer SoCs and better identification
- Minor fixes for Broadcom, Freescale, Apple, Renesas, Sifive,
TI, Mediatek and Marvell SoC drivers

arm64 updates for 6.2
ACPI:
* Enable FPDT support for boot-time profiling
* Fix CPU PMU probing to work better with PREEMPT_RT
* Update SMMUv3 MSI DeviceID parsing to latest IORT spec
* APMT support for probing Arm CoreSight PMU devices
CPU features:
* Advertise new SVE instructions (v2.1)
* Advertise range prefetch instruction
* Advertise CSSC ("Common Short Sequence Compression") scalar
instructions, adding things like min, max, abs, popcount
* Enable DIT (Data Independent Timing) when running in the kernel
* More conversion of system register fields over to the generated
header
CPU misfeatures:
* Workaround for Cortex-A715 erratum #2645198
Dynamic SCS:
* Support for dynamic shadow call stacks to allow switching at
runtime between Clang's SCS implementation and the CPU's
pointer authentication feature when it is supported (complete
with scary DWARF parser!)
Tracing and debug:
* Remove static ftrace in favour of, err, dynamic ftrace!
* Seperate 'struct ftrace_regs' from 'struct pt_regs' in core
ftrace and existing arch code
* Introduce and implement FTRACE_WITH_ARGS on arm64 to replace
the old FTRACE_WITH_REGS
* Extend 'crashkernel=' parameter with default value and fallback
to placement above 4G physical if initial (low) allocation
fails
SVE:
* Optimisation to avoid disabling SVE unconditionally on syscall
entry and just zeroing the non-shared state on return instead
Exceptions:
* Rework of undefined instruction handling to avoid serialisation
on global lock (this includes emulation of user accesses to the
ID registers)
Perf and PMU:
* Support for TLP filters in Hisilicon's PCIe PMU device
* Support for the DDR PMU present in Amlogic Meson G12 SoCs
* Support for the terribly-named "CoreSight PMU" architecture
from Arm (and Nvidia's implementation of said architecture)
Misc:
* Tighten up our boot protocol for systems with memory above
52 bits physical
* Const-ify static keys to satisty jump label asm constraints
* Trivial FFA driver cleanups in preparation for v1.1 support
* Export the kernel_neon_* APIs as GPL symbols
* Harden our instruction generation routines against
instrumentation
* A bunch of robustness improvements to our arch-specific selftests
* Minor cleanups and fixes all over (kbuild, kprobes, kfence, PMU, ...)

Pull slab updates from Vlastimil Babka:
- SLOB deprecation and SLUB_TINY
The SLOB allocator adds maintenance burden and stands in the way of
API improvements [1]. Deprecate it by renaming the config option (to
make users notice) to CONFIG_SLOB_DEPRECATED with updated help text.
SLUB should be used instead as SLAB will be the next on the removal
list.
Based on reports from a riscv k210 board with 8MB RAM, add a
CONFIG_SLUB_TINY option to minimize SLUB's memory usage at the
expense of scalability. This has resolved the k210 regression [2] so
in case there are no others (that wouldn't be resolvable by further
tweaks to SLUB_TINY) plan is to remove SLOB in a few cycles.
Existing defconfigs with CONFIG_SLOB are converted to
CONFIG_SLUB_TINY.
- kmalloc() slub_debug redzone improvements
A series from Feng Tang that builds on the tracking or requested size
for kmalloc() allocations (for caches with debugging enabled) added
in 6.1, to make redzone checks consider the requested size and not
the rounded up one, in order to catch more subtle buffer overruns.
Includes new slub_kunit test.
- struct slab fields reordering to accomodate larger rcu_head
RCU folks would like to grow rcu_head with debugging options, which
breaks current struct slab layout's assumptions, so reorganize it to
make this possible.
- Miscellaneous improvements/fixes:
- __alloc_size checking compiler workaround (Kees Cook)
- Optimize and cleanup SLUB's sysfs init (Rasmus Villemoes)
- Make SLAB compatible with PROVE_RAW_LOCK_NESTING (Jiri Kosina)
- Correct SLUB's percpu allocation estimates (Baoquan He)
- Re-enableS LUB's run-time failslab sysfs control (Alexander Atanasov)
- Make tools/vm/slabinfo more user friendly when not run as root (Rong Tao)
- Dead code removal in SLUB (Hyeonggon Yoo)

Merge tag 'printk-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
- Add NMI-safe SRCU reader API. It uses atomic_inc() instead of
this_cpu_inc() on strong load-store architectures.
- Introduce new console_list_lock to synchronize a manipulation of the
list of registered consoles and their flags.
This is a first step in removing the big-kernel-lock-like behavior of
console_lock(). This semaphore still serializes console->write()
calbacks against:
- each other. It primary prevents potential races between early
and proper console drivers using the same device.
- suspend()/resume() callbacks and init() operations in some
drivers.
- various other operations in the tty/vt and framebufer
susbsystems. It is likely that console_lock() serializes even
operations that are not directly conflicting with the
console->write() callbacks here. This is the most complicated
big-kernel-lock aspect of the console_lock() that will be hard
to untangle.
- Introduce new console_srcu lock that is used to safely iterate and
access the registered console drivers under SRCU read lock.
This is a prerequisite for introducing atomic console drivers and
console kthreads. It will reduce the complexity of serialization
against normal consoles and console_lock(). Also it should remove the
risk of deadlock during critical situations, like Oops or panic, when
only atomic consoles are registered.
- Check whether the console is registered instead of enabled on many
locations. It was a historical leftover.
- Cleanly force a preferred console in xenfb code instead of a dirty
hack.
- A lot of code and comment clean ups and improvements.

There is a new helper to indicate whether any locks are held on an inode. This is mostly for Ceph but may be usable elsewhere too. Andi Kleen requested that we print the PID when the LOCK_MAND warning fires, to help track down applications trying to use it. Finally, we added some new warnings to some of the file locking functions that fire when the ->fl_file and filp arguments differ. This helped us find some long-standing bugs in lockd.

RCU pull request for v6.2
This pull request contains the following branches: doc.2022.10.20a: Documentation updates. This is the second in a series from an ongoing review of the RCU documentation. fixes.2022.10.21a: Miscellaneous fixes. lazy.2022.11.30a: Introduces a default-off Kconfig option that depends on RCU_NOCB_CPU that, on CPUs mentioned in the nohz_full or rcu_nocbs boot-argument CPU lists, causes call_rcu() to introduce delays. These delays result in significant power savings on nearly idle Android and ChromeOS systems. These savings range from a few percent to more than ten percent. This series also includes several commits that change call_rcu() to a new call_rcu_hurry() function that avoids these delays in a few cases, for example, where timely wakeups are required. Several of these are outside of RCU and thus have acks and reviews from the relevant maintainers. srcunmisafe.2022.11.09a: Creates an srcu_read_lock_nmisafe() and an srcu_read_unlock_nmisafe() for architectures that support NMIs, but which do not provide NMI-safe this_cpu_inc(). These NMI-safe SRCU functions are required by the upcoming lockless printk() work by John Ogness et al. That printk() series depends on these commits, so if you pull the printk() series before this one, you will have already pulled in this branch, plus two more SRCU commits: |
