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.

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().

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...

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.

i2c: nomadik: fix BRCR computation
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).

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.

The biggest change here is eliminating the awful idea that KVM had, of
essentially guessing which pfns are refcounted pages. The reason to
do so was that KVM needs to map both non-refcounted pages (for example
BARs of VFIO devices) and VM_PFNMAP/VM_MIXMEDMAP VMAs that contain
refcounted pages. However, the result was security issues in the past,
and more recently the inability to map VM_IO and VM_PFNMAP memory
that _is_ backed by struct page but is not refcounted. In particular
this broke virtio-gpu blob resources (which directly map host graphics
buffers into the guest as "vram" for the virtio-gpu device) with the
amdgpu driver, because amdgpu allocates non-compound higher order pages
and the tail pages could not be mapped into KVM.
This requires adjusting all uses of struct page in the per-architecture
code, to always work on the pfn whenever possible. The large series that
did this, from David Stevens and Sean Christopherson, also cleaned up
substantially the set of functions that provided arch code with the
pfn for a host virtual addresses. The previous maze of twisty little
passages, all different, is replaced by five functions (__gfn_to_page,
__kvm_faultin_pfn, the non-__ versions of these two, and kvm_prefetch_pages)
saving almost 200 lines of code.
ARM:
* Support for stage-1 permission indirection (FEAT_S1PIE) and
permission overlays (FEAT_S1POE), including nested virt + the
emulated page table walker
* Introduce PSCI SYSTEM_OFF2 support to KVM + client driver. This call
was introduced in PSCIv1.3 as a mechanism to request hibernation,
similar to the S4 state in ACPI
* Explicitly trap + hide FEAT_MPAM (QoS controls) from KVM guests. As
part of it, introduce trivial initialization of the host's MPAM
context so KVM can use the corresponding traps
* PMU support under nested virtualization, honoring the guest
hypervisor's trap configuration and event filtering when running a
nested guest
* Fixes to vgic ITS serialization where stale device/interrupt table
entries are not zeroed when the mapping is invalidated by the VM
* Avoid emulated MMIO completion if userspace has requested synchronous
external abort injection
* Various fixes and cleanups affecting pKVM, vCPU initialization, and
selftests
LoongArch:
* Add iocsr and mmio bus simulation in kernel.
* Add in-kernel interrupt controller emulation.
* Add support for virtualization extensions to the eiointc irqchip.
PPC:
* Drop lingering and utterly obsolete references to PPC970 KVM, which was
removed 10 years ago.
* Fix incorrect documentation references to non-existing ioctls
RISC-V:
* Accelerate KVM RISC-V when running as a guest
* Perf support to collect KVM guest statistics from host side
s390:
* New selftests: more ucontrol selftests and CPU model sanity checks
* Support for the gen17 CPU model
* List registers supported by KVM_GET/SET_ONE_REG in the documentation
x86:
* Cleanup KVM's handling of Accessed and Dirty bits to dedup code, improve
documentation, harden against unexpected changes. Even if the hardware
A/D tracking is disabled, it is possible to use the hardware-defined A/D
bits to track if a PFN is Accessed and/or Dirty, and that removes a lot
of special cases.
* Elide TLB flushes when aging secondary PTEs, as has been done in x86's
primary MMU for over 10 years.
* Recover huge pages in-place in the TDP MMU when dirty page logging is
toggled off, instead of zapping them and waiting until the page is
re-accessed to create a huge mapping. This reduces vCPU jitter.
* Batch TLB flushes when dirty page logging is toggled off. This reduces
the time it takes to disable dirty logging by ~3x.
* Remove the shrinker that was (poorly) attempting to reclaim shadow page
tables in low-memory situations.
* Clean up and optimize KVM's handling of writes to MSR_IA32_APICBASE.
* Advertise CPUIDs for new instructions in Clearwater Forest
* Quirk KVM's misguided behavior of initialized certain feature MSRs to
their maximum supported feature set, which can result in KVM creating
invalid vCPU state. E.g. initializing PERF_CAPABILITIES to a non-zero
value results in the vCPU having invalid state if userspace hides PDCM
from the guest, which in turn can lead to save/restore failures.
* Fix KVM's handling of non-canonical checks for vCPUs that support LA57
to better follow the "architecture", in quotes because the actual
behavior is poorly documented. E.g. most MSR writes and descriptor
table loads ignore CR4.LA57 and operate purely on whether the CPU
supports LA57.
* Bypass the register cache when querying CPL from kvm_sched_out(), as
filling the cache from IRQ context is generally unsafe; harden the
cache accessors to try to prevent similar issues from occuring in the
future. The issue that triggered this change was already fixed in 6.12,
but was still kinda latent.
* Advertise AMD_IBPB_RET to userspace, and fix a related bug where KVM
over-advertises SPEC_CTRL when trying to support cross-vendor VMs.
* Minor cleanups
* Switch hugepage recovery thread to use vhost_task. These kthreads can
consume significant amounts of CPU time on behalf of a VM or in response
to how the VM behaves (for example how it accesses its memory); therefore
KVM tried to place the thread in the VM's cgroups and charge the CPU
time consumed by that work to the VM's container. However the kthreads
did not process SIGSTOP/SIGCONT, and therefore cgroups which had KVM
instances inside could not complete freezing. Fix this by replacing the
kthread with a PF_USER_WORKER thread, via the vhost_task abstraction.
Another 100+ lines removed, with generally better behavior too like
having these threads properly parented in the process tree.
* Revert a workaround for an old CPU erratum (Nehalem/Westmere) that didn't
really work; there was really nothing to work around anyway: the broken
patch was meant to fix nested virtualization, but the PERF_GLOBAL_CTRL
MSR is virtualized and therefore unaffected by the erratum.
* Fix 6.12 regression where CONFIG_KVM will be built as a module even
if asked to be builtin, as long as neither KVM_INTEL nor KVM_AMD is 'y'.
x86 selftests:
* x86 selftests can now use AVX.
Documentation:
* Use rST internal links
* Reorganize the introduction to the API document
Generic:
* Protect vcpu->pid accesses outside of vcpu->mutex with a rwlock instead
of RCU, so that running a vCPU on a different task doesn't encounter long
due to having to wait for all CPUs become quiescent. In general both reads
and writes are rare, but userspace that supports confidential computing is
introducing the use of "helper" vCPUs that may jump from one host processor
to another. Those will be very happy to trigger a synchronize_rcu(), and
the effect on performance is quite the disaster.

- Support for the gen17 CPU model
- List registers supported by KVM_GET/SET_ONE_REG in the
documentation
x86:
- Cleanup KVM's handling of Accessed and Dirty bits to dedup code,
improve documentation, harden against unexpected changes.
Even if the hardware A/D tracking is disabled, it is possible to
use the hardware-defined A/D bits to track if a PFN is Accessed
and/or Dirty, and that removes a lot of special cases.
- Elide TLB flushes when aging secondary PTEs, as has been done in
x86's primary MMU for over 10 years.
- Recover huge pages in-place in the TDP MMU when dirty page logging
is toggled off, instead of zapping them and waiting until the page
is re-accessed to create a huge mapping. This reduces vCPU jitter.
- Batch TLB flushes when dirty page logging is toggled off. This
reduces the time it takes to disable dirty logging by ~3x.
- Remove the shrinker that was (poorly) attempting to reclaim shadow
page tables in low-memory situations.
- Clean up and optimize KVM's handling of writes to
MSR_IA32_APICBASE.
- Advertise CPUIDs for new instructions in Clearwater Forest
- Quirk KVM's misguided behavior of initialized certain feature MSRs
to their maximum supported feature set, which can result in KVM
creating invalid vCPU state. E.g. initializing PERF_CAPABILITIES to
a non-zero value results in the vCPU having invalid state if
userspace hides PDCM from the guest, which in turn can lead to
save/restore failures.
- Fix KVM's handling of non-canonical checks for vCPUs that support
LA57 to better follow the "architecture", in quotes because the
actual behavior is poorly documented. E.g. most MSR writes and
descriptor table loads ignore CR4.LA57 and operate purely on
whether the CPU supports LA57.
- Bypass the register cache when querying CPL from kvm_sched_out(),
as filling the cache from IRQ context is generally unsafe; harden
the cache accessors to try to prevent similar issues from occuring
in the future. The issue that triggered this change was already
fixed in 6.12, but was still kinda latent.
- Advertise AMD_IBPB_RET to userspace, and fix a related bug where
KVM over-advertises SPEC_CTRL when trying to support cross-vendor
VMs.
- Minor cleanups
- Switch hugepage recovery thread to use vhost_task.
These kthreads can consume significant amounts of CPU time on
behalf of a VM or in response to how the VM behaves (for example
how it accesses its memory); therefore KVM tried to place the
thread in the VM's cgroups and charge the CPU time consumed by that
work to the VM's container.
However the kthreads did not process SIGSTOP/SIGCONT, and therefore
cgroups which had KVM instances inside could not complete freezing.
Fix this by replacing the kthread with a PF_USER_WORKER thread, via
the vhost_task abstraction. Another 100+ lines removed, with
generally better behavior too like having these threads properly
parented in the process tree.
- Revert a workaround for an old CPU erratum (Nehalem/Westmere) that
didn't really work; there was really nothing to work around anyway:
the broken patch was meant to fix nested virtualization, but the
PERF_GLOBAL_CTRL MSR is virtualized and therefore unaffected by the
erratum.
- Fix 6.12 regression where CONFIG_KVM will be built as a module even
if asked to be builtin, as long as neither KVM_INTEL nor KVM_AMD is
'y'.
x86 selftests:
- x86 selftests can now use AVX.
Documentation:
- Use rST internal links
- Reorganize the introduction to the API document
Generic:
- Protect vcpu->pid accesses outside of vcpu->mutex with a rwlock
instead of RCU, so that running a vCPU on a different task doesn't
encounter long due to having to wait for all CPUs become quiescent.
In general both reads and writes are rare, but userspace that
supports confidential computing is introducing the use of "helper"
vCPUs that may jump from one host processor to another. Those will
be very happy to trigger a synchronize_rcu(), and the effect on
performance is quite the disaster"

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:

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().

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.

Summary
* sysctl ctl_table constification
Constifying ctl_table structs prevents the modification of proc_handler
function pointers. All ctl_table struct arguments are const qualified in the
sysctl API in such a way that the ctl_table arrays being defined elsewhere
and passed through sysctl can be constified one-by-one. We kick the
constification off by qualifying user_table in kernel/ucount.c and expect all
the ctl_tables to be constified in the coming releases.
* Misc fixes
Adjust comments in two places to better reflect the code. Remove superfluous
dput calls. Remove Luis from sysctl maintainership. Replace comments about
holding a lock with calls to lockdep_assert_held.
* Testing
All these went through 0-day and they have all been in linux-next for at
least 1 month (since Oct-24). I also rand these through the sysctl selftest
for x86_64.

MTD device changes: Aside from the platform_driver::remove() switch, two
misc issues got fixed.
SPI-NAND changes:
A load of fixes to Winbond manufacturer driver have been done, plus a
structure constification.
Raw NAND changes:
The GPMI driver has been improved on the power management side.
The Davinci driver has been cleaned up.
A leak in the Atmel driver plus some typos in the core have been fixed.
SPI NOR changes:
Introduce byte swap support for 8D-8D-8D mode and a user for it:
macronix. SPI NOR flashes may swap the bytes on a 16-bit boundary when
configured in Octal DTR mode. For such cases the byte order is
propagated through SPI MEM to the SPI controllers so that the
controllers swap the bytes back at runtime. This avoids breaking the
boot sequence because of the endianness problems that appear when the
bootloaders use 1-1-1 and the kernel uses 8D-8D-8D with byte swap
support. Along with the SPI MEM byte swap support we queue a patch for
the SPI MXIC controller that swaps the bytes back at runtime.

The core framework gained a clk provider helper, a clk consumer helper, and
some unit tests for the assigned clk rates feature in DeviceTree. On the vendor
driver side, we gained a whole pile of SoC driver support detailed below. The
majority in the diffstat is Qualcomm, but there's also quite a few Samsung and
Mediatek clk driver additions in here as well. The top vendors is quite common,
but the sheer amount of new drivers is uncommon, so I'm anticipating a larger
number of fixes for clk drivers this cycle.
Core:
- devm_clk_bulk_get_all_enabled() to return number of clks acquired
- devm_clk_hw_register_gate_parent_hw() helper to modernize drivers
- KUnit tests for clk-assigned-rates{,-u64}
New Drivers:
- Marvell PXA1908 SoC clks
- Mobileye EyeQ5, EyeQ6L and EyeQ6H clk driver
- TWL6030 clk driver
- Nuvoton Arbel BMC NPCM8XX SoC clks
- MediaTek MT6735 SoC clks
- MediaTek MT7620, MT7628 and MT7688 MMC clks
- Add a driver for gated fixed rate clocks
- Global clock controllers for Qualcomm QCS8300 and IPQ5424 SoCs
- Camera, display and video clock controllers for Qualcomm SA8775P SoCs
- Global, display, GPU, TCSR, and RPMh clock controllers for Qualcomm SAR2130P
- Global, camera, display, GPU, and video clock controllers for Qualcomm
SM8475 SoCs
- RTC power domain and Battery Backup Function (VBATTB) clock support for the
Renesas RZ/G3S SoC
- Qualcomm IPQ9574 alpha PLLs
- Support for i.MX91 CCM in the i.MX93 driver
- Microchip LAN969X SoC clks
- Cortex-A55 core clocks and Interrupt Control Unit (ICU) clock and reset on
Renesas RZ/V2H(P)
- Samsung ExynosAutov920 clk drivers for PERIC1, MISC, HSI0 and HSI1
- Samsung Exynos8895 clk drivers for FSYS0/1, PERIC0/1, PERIS and TOP
Updates:
- Convert more clk bindings to YAML
- Various clk driver cleanups: NULL checks, add const, etc.
- Remove END/NUM #defines that count number of clks in various binding headers
- Continue moving reset drivers to drivers/reset via auxiliary bus

- Several drivers, including atmel-flexcom/rk8xx-core, palmas, and
tps65010, have undergone minor code improvements to enhance consistency and fix race conditions. - The syscon driver now utilizes the regmap max_register_is_0 capability for consistent register map configuration across syscons of all sizes. - New device support has been added for QCS8300, qcs615, SA8255p, and samsung,s2dos05, expanding the range of compatible hardware. - The cros_ec driver now supports loading cros_ec_ucsi on supported ECs and avoids loading the charger with UCSI, streamlining functionality. - The bd96801 driver now utilizes the more modern maple tree register cache, improving performance. - The da9052-spi driver has undergone a fix to change the read-mask to write-mask, preventing potential issues. - Unused declarations in max77693 have been removed, and support for samsung,s2dos05 has been added, enhancing code clarity and device compatibility. - Error handling in cs42l43 has been fixed to avoid unbalanced regulator put and ensure proper synchronization during driver removal. - The wcd934x driver now uses MODULE_DEVICE_TABLE() instead of MODULE_ALIAS(), improving code consistency. - Documentation for qcom,tcsr, syscon, and atmel-smc has been updated and reorganized for better clarity and maintainability. - The intel_soc_pmic_bxtwc driver has undergone significant improvements, including the use of IRQ domains for various devices, fixing IRQ domain names duplication, and code refactoring for better consistency and maintainability. - The ipaq-micro driver has received a fix for a missing break statement in the default case, enhancing code robustness. - Support for the AXP323 PMIC has been added to the axp20x driver, along with ensuring a clear relationship between IDs and model names, and allowing multiple regulators, broadening hardware compatibility. - The cs42l43 driver now disables IRQs during suspend for improved power management. - The adp5585 driver has reduced its dependencies by dropping the obsolete dependency on COMPILE_TEST. - Initial support for the MT6328 PMIC has been added to the mt6397 driver, expanding the range of supported hardware. -

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.

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.
