i2c: ocores: Disable clock on failed resume
ocores_i2c_resume() enables the controller clock before reinitializing
the hardware. If the clock rate changed while the device was suspended,
ocores_init() may reject the resulting prescaler. The callback then
returns an error with the clock still enabled, while the controller
itself remains disabled.
Disable and unprepare the clock when ocores_init() fails so the failed
resume path balances the successful clk_prepare_enable() call.
This issue was found by a static analysis checker and confirmed by manual
source review.

i2c: imx-lpi2c: reset controller in probe stage
Reset I2C controller in probe stage to avoid unexpected LPI2C controller state left from previous stages and hang system boot. Per the LPI2C reference manual, section 7.1.4 "Controller Control (MCR)" and 7.1.20 Target Control (SCR), the RST bit (bit 1) description states: "The reset takes effect immediately and remains asserted until negated by software. There is no minimum delay required before clearing the software reset." Therefore, it is safe to write 0 to MCR and SCR immediately after asserting the RST bit without any additional delay.

i2c: imx-lpi2c: properly unwind resources on probe failure
When probe fails at devm_clk_rate_exclusive_get() or clk_get_rate(), which occur before runtime PM is initialized, the clocks enabled by clk_bulk_prepare_enable() are never disabled. When probe fails after runtime PM is initialized, the previous error path called pm_runtime_put_sync(), which triggers the runtime suspend callback. However, due to different clock management strategies on different SoCs[1] (to avoid deadlocks between the global prepare_lock and runtime PM), the callback may only disable clocks without unpreparing them, causing an incomplete unwind. Introduce a new error label 'clk_disable' to explicitly invoke clk_bulk_disable_unprepare(). Replace pm_runtime_put_sync() with the sequence of pm_runtime_disable(), pm_runtime_set_suspended() and pm_runtime_put_noidle() to bypass the runtime suspend callback during error recovery. During the LPI2C driver probe phase, clock APIs are used exclusively to manage clocks. Once probing succeeds, clock management is handed over to the runtime PM core.

i2c: busses: drop redundant dev_err_probe() around irq helpers
platform_get_irq(), devm_request_irq() and devm_request_threaded_irq() already print an error message via dev_err_probe() on failure, so wrapping their return value with another dev_err_probe() results in duplicate error output. Drop these redundant dev_err_probe() calls across i2c bus drivers and return the error code directly instead.

soc: Arm platform updates for 7.3
The 32-bit Arm platforms are a bit more interesting this time: I refreshed
an earlier series to mark code as deprecated that does have the tendency
of getting in the way of cleanups and new features but has close to zero
users. Among these are:
- 22 of the remaining 28 legacy board files that predate the current
devicetree based descriptions, using old chips from Intel and Marvell.
The remaining six board files are for TI OMAP1 and Samsung s3c64xx
chips and all still have known users.
- support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25
machines based on these. These all use devicetree but the CPU
support causes disproportional work. Most of them are just
reference boards, the notable exceptions being the Nokia N800/N810
tablet and the Buglabs BUG platform.
- be8, be32, oabi and iwmmxt userspace binaries, which were mostly
associated with the platforms now scheduled for removal and
are increasingly problematic to support with modern toolchains.
Nothing is actually removed at this point, to ensure that any remaining
users continue to have the 7.3-LTS for a while longer. Patches for
removal are currently being tested.
Other updates include a continued work to convert GPIO number based
interfaces to descriptors, a patch to restore little-endian mode
on the one Arm platform (ixp4xx) that only worked in big-endian mode
recently, and some minor cleanups and bugfixes.

soc: drivers for 7.3
The SoC driver changes once more consist of many small fixes and
cleanups, that are to a large part the result of automated testing. On
platform specific drivers, this includes SoC specific code for xilinx,
freescale/nxp, qualcomm, TI, aspeed, omap, tegra, samsung, rockchip,
renesas, ixp4xx. In firmware drivers, we see a similar picture for
SCMI and qcomtee.
Aside from these, we see actual new hardware support in a few
areas:
- The Apple platform gets a new driver for low power states
- Updates to Qualcomm platform drivers add several new
hardware specific features and additional SoCs.
- Amlogic SoC support for A1 and T7 is added
- The Mediatek MMSYS driver is refactored as a cleanup.

soc: devicetree updates for 7.3
There are two new mystery SoCs with very little public information
about them so far, Qualcomm's Cortex-A78C based "Shikra" and
Altera's Cortex-A720 based Agilex72 SOCFPGA.
We have also gained support for a couple of SoCs from the
2023/2024 timeframe that have been in the making for a while:
- The Apple platform gains support for M3 Pro, Max and Ultra SoC,
following the basic M3 support from 7.2.
- Samsung Exynos 1580 is a high-end mobile phone SoC from 2024
- Canaan K230 is a RISC-V based 64-bit AI SoC, based on the
earlier K210 chip
- Sophgo SG2000 is a mixed Arm/RISC-V chip that was already
supported using the Arm core but is now also added for RISC-V
along with several other variants of the cv18xx series
In terms of newly added machines we have reference platforms
for all the chips above, plus
- only four 32-bit Arm boards: two older phones and two
older industrial/embedded boards; using Allwinner, Qualcomm and
Rockchip SoCs
- Three laptops und three phones using Qualcomm SoCs
- Ten 64-bit Rockchips based single-board computers, along with one
NAS box and a game console.
- Seven industrial/embedded boards and modules using NXP i.MX8/9 SoCs.
- A Lenovo desktop box based on NVIDIA Jetson Xavier NX
- A few more single-board computers based on Allwinnner A133,
Spacemit K1 and TI AM62.
As usual, there is a constant stream of minor cleanups and fixes
towards addressing the 'dt-check-style --mode strict' warnings,
and everyone is expected to address those warnings for new
submissions now.

Merge tag 'x86_mm_for_7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 mm updates from Dave Hansen:
"There are two things in here of note. First, there are fixes to reduce
the time that the TLB flushing code sits around with interrupts
disabled. It should be well tested, but it's certainly something to
keep an eye on.
Second is a little back-and-forth in the interactions between the
set_memory*() locking and DEBUG_PAGEALLOC. There was a slightly
painful re-discovery of why DEBUG_PAGEALLOC has special locking rules,
but the code did end up better for it.
Summary:
- Fix pkey_alloc() return value when pkeys are not supported
- Allow preemption during IPI completion waiting to improve wakeup
latency
- Convert more x86 page table code to ptdescs
- Fixes and cleanups for set_memory*() locking, mostly around large
pages"

VDSO updates:
- Consolidate the VDSO datastore further and provide support for
mlock_all() and prefaulting.
- Provide 32-bit legacy time related functionality only if
CONFIG_COMPAT_32BIT_TIME is enabled. The config switch exists, but
architecture code still exposes the legacy functionality even disabled.
Clean this up by adding the missing guards and validating at build time
that the VDSO is legacy free if disabled.
- Consolidate the VDSO related config options in core and drivers, which
removes some non-sensical dependencies and quite an amount of #ifdeffery.
- Clean up the PAGE_SIZE definition maze

Timers and timekeeping core updates:
- Fix a subtly inconsistency in the timekeeping code, which fails to
account for the monotonicity adjustment in ntp_error. For small changes
of the clocksource multiplicator (+/-1) which are typically used by the
NTP PLL this is hardly to observe. But for larger adjustments,
e.g. caused by a direct frequency setting through adjtimex() the
one-time uncompensated offset is significant.
Cure this by adjusting ntp_error with the resulting offset so that the
discrepancy is smoothed away over time
- Make tick length calculations correct in NTP. The timekeeping core
takes the quantisation of the clocksource into account when calculating
the tick length to compensate for the deviation of the nominal
NTP_INTERVAL_LENGTH. While timekeeping gets this right, NTP is not
aware of that, which means it operates on the nominal value and not on
the actual value which is determined by the clock source frequency. The
rounding of a coarse clocksource like the ACPI PM timer results in a
+127 PPM deviation.
Cure this by exposing the deviation to the NTP code so that it can
operate on the same data as the timekeeping core. This is purely kernel
internal. User space still sees the nominal tick lenght via adjtimex().
- The accuracy of the NTP adjustments is fairly approximate as the code
assumes that the invocations are precisely in NTP interval frequency
ticks and the final adjustment can over and under-run.
Cure this by adjusting ntp_error by the intended skew on each tick to
achieve the desired rate.
- Handle the two competing skews of time offset and time adjustment
correctly by calculating the conflict portion between the skews and
adjusting both accordingly.
- A set of updates and improvements for the selftests
- The usual small fixes and improvements all over the place

Treewide timer related cleanups:
- Remove the leftover CLOCK_TICK_RATE which has been scheduled for
removal more than a decade ago along with some now empty asm/timex.h
files.
- Consolidate delay timer calibration
The construct of having a define in a header requires that
architectures provided asm/timex.h for no reason. Also the function
name for reading the delay timer is confusing at best.
Use a config switch to enable that functionality and rename the
function to delay_read_timer() to make the purpose clear.
This removes some more now empty asm/timex.h files as well.

SMP core updates:
- Reduce the preemption disabled sections in smp_call_function*().
The various smp call functions keep preemption disabled accross the
full operation which includes the wait for completion. Especially the
latter can take some time when one of the target CPUs is not
immediately responding to the IPI, which can result in large latency
spikes.
To improve this provide a per task CPU mask to track the CPUs to wait
for. That makes the information required for the wait task local and
therefore allows to reenable preemption before the wait. While this
comes with moderate extra memory cost this reduces SMP function call
induced latency measured in a fleet for high priority tasks from ~17ms
to ~1.5ms (~90%).
- Reduce the overhead of the CSD debug code by replacing the heavy memory
barriers with smp_store_release()/acquire().
- Remove obsolute unused hotplug states

Pull futex updates from Thomas Gleixner:
- Improvements to various futex self tests:
- Conversion to the selftest harness
- Provide and use thread creation and synchronization helpers to
reduce the dependency on delays, which tend to fail on loaded test
systems
- New tests for validating owner exit scenarios for robust and PI
futexes
- Runtime detect supported features and skip the tests if the kernel
has no support
- A few minor fixes

Interrupt chip driver updates:
- Update the realtek-rtl driver to support multiple interrupt domains and
remove hardcoded assumptions about the underlying demultiplex interrupt
- Remove the unused IMGPDC driver, which got orphaned when the metag
architecture was removed long ago.
- Update the Qualcom PDC interrupt chip driver to support differnent
versions of the IP block, to properly differentiable between direct and
GPIO based interrupts and to utilize pass through mode to the
underlying GIC interrupt.
- Remove redundant dev_err() and dev_err_probe() invocations in various
drivers as that error logging has been moved to devm_request_*_irq().
- Support dynamic MSI-X allocations in the GIC-V3-ITS MSI parent domain
driver. That's important for VFIO pass through devices to avoid
reinitialization of the MSI-X space when extending the vector
range. Such a reinitialization can result is lost interrupts and stale
devices.
- Fix a bunch of resource leaks in various driver error paths/
- The usual small improvements all over the place

Generic entry code updates:
- Make syscall user dispatching configurable
Not all architectures can makes use of syscall user dispatching. Allow
them to disable the feature completely.
- Consolidate stack randomization for the generic entry code and the
architectures using it.
Stack randomization on syscall entry was sprinkled throughout the
architecture specific low level entry code and in some cases at the
wrong points, e.g. before establishing state, which violates the
non-instrumentable constraints of that code.
Clean this up by integrating stack randomization into the generic entry
code helpers so that it is invoked at the earliest possible point right
after establishing state and converting all generic entry code using
architecture over.
- Clean up the syscall number handling in the generic entry code. It
works correctly for architectures which have a separate return value
storage in pt_regs, but fails to distinguish the case where user space
handed in -1 as syscall number from the case where the entry code
rejects it by returning -1 to the callers. Aside of that the return
value functionality of those interfaces is not really intuitive.
Fix this by separating the decision to reject a syscall (user dispatch,
ptrace, seccomp ...) from the potential modification of the syscall
number through these mechanisms.
This solves most of the problems for architectures which do not have a
separate return value storage in pt_regs except for the case where a
tracepoint has a BPF script or a probe attached which overwrite both
the syscall number and the return value. But that's a problem which
cannot be solved in the generic code, that only can be addressed by
separating the storage model in the affected architectures.

Scheduler updates for v7.3:
Load-balancing updates:
- Series to 'flatten the pick': improve cgroup scheduling, which has
always been problematic and painful, which has caused various
scheduling misbehavior such as the mishandling of reniced tasks et al.
Add various cgroup weight distribution methods via cgroup_mode:
'up', 'max', 'concur' and 'tasks' - with the default being 'concur'
which is the most precise yet also most expensive version.
Finally, change cgroup scheduling to a single runqueue.
(Peter Zijlstra)
- Series to improve the scheduling latency of short slice tasks
(Vincent Guittot)
- Series to fix cluster scheduling in the presence of asymmetric capacity
(Ricardo Neri)
- Prefer fully idle cores for NOHZ balancing (Andrea Righi)
- Don't trigger active load-balancing if src_rq->curr is not on_rq
(Xin Zhao)
PSI updates:
- Skip irqtime accounting when no new irq time has elapsed
(Usama Arif)
Scheduler debugging updates:
- Remove unused schedstats (Shrikanth Hegde)
- Defer freeing of cpumask memblock memory to initcall
(Waiman Long)
Misc fixes and updates by Yu C Chen, K Prateek Nayak, Peter Zijlstra,
Vincent Guittot, Xin Zhao, Yury Norov, Zhan Xusheng.

Performance events updates for v7.3:
uprobes updates:
- Patch series to fix a category of bugs with optimized uprobes that
can clobber the redzone area with call instruction storing return
address on stack where user code may keep temporary data without
adjusting RSP. Fix this by moving the optimized uprobes on top of
10-bytes NOP instruction, so we can squeeze another instruction to
escape the redzone area before doing the call.
(Jiri Olsa, Andrii Nakryiko)

(Puranjay Mohan)

Rust changes for v7.3
Toolchain and infrastructure:
- Warn when using 'bindgen' < 0.72.1 with 'libclang' >= 22, since that
combination may fail to build. It includes a probe for the bug in
case 'bindgen' happens to be patched, and tests.
In parallel, Nathan updated the instructions for the kernel.org
LLVM+Rust toolchains so that the latest version of 'bindgen' is
installed, which should avoid some of these situations.
- Support testing 'rust_is_available.sh' with 'bash' as '/bin/sh'.
- Fix an objtool warning by adding one more 'noreturn' function for
Rust 1.99.0 (expected 2026-10-01).
- Fix build error in the 'rusttest' target due to ambiguity when the
'rustc-dev' component is installed, which was uncovered by the work
to support Rust's GCC backend ('rustc_codegen_gcc').
- Fix future Clang warnings in the upcoming powerpc support due to
macro redefinitions in the UAPI helper header by including the
arch-aware 'ioctl.h' header.
'kernel' crate:
- Rework module ownership support:
- Move the module-related types into a new 'module' module and make
the 'THIS_MODULE' pointer a constant of 'ModuleMetadata' so that
modules can provide the pointer in const contexts, and add a
'this_module' 'const fn' to retrieve it.
This was enabled by upstream Rust's work on the 'const_mut_refs'
and 'const_refs_to_static' features which were stabilized back
in Rust 1.83.0.
- Teach '#[vtable]' to associate implementations with their owning
module, defaulting to the local one, including fallbacks for
doctests, uses within the 'kernel' crate (like upcoming KUnit
'#[test]'s for DRM) and 'rusttest'.
- Set 'fops.owner' from the module pointer for DRM and miscdevice.
- Migrate Rust Binder and configfs away from the old 'THIS_MODULE'
'static' and finally remove it from the 'module!' macro.
- 'num' module:
- Add the new 'casts' module for lossless integer conversions.
Rust's 'core' library's 'From' implementations do not cover
conversions that are not portable or future-proof. However, the
kernel supports a narrower set of architectures, which makes it
helpful to provide more infallible conversions, instead of having
developers use 'as' casts, which carry the risk of silently
losing data.
This goes along with previous work we did to avoid casts in Rust
kernel code since they are more powerful than needed.
Thus, provide safe 'const' conversion functions (e.g.
'usize_as_u64' and 'u64_into_u8'), as well as the 'FromSafeCast'
and 'IntoSafeCast' extension traits that provide conversions that
are known to be lossless in the kernel, and an 'arch' submodule
defining conversions that are known to be lossless on particular
architectures (e.g. 64-bit platforms). For instance:
// Conversion in const context.
const USIZED_CONST: usize = u8_as_usize(255u8);
// Non-const conversions.
let a = u64::from_safe_cast(4096usize);
let b: u64 = 4096usize.into_safe_cast();
- Add 'Bounded::shr_exact' method in the vein of 'try_shrink' which
shifts a bounded right only if it loses no set bits.
- Fix unsoundness issue in the 'Bounded::shr' method by rejecting,
at compile-time, shifts of at least the type's bit width.
- 'fmt' module:
- Route '{:p}' raw pointer formatting through the kernel's hashed
'%p' format to prevent address leaks, including support for width
and padding. Include tests for both 'no_hash_pointers' case and
the default (hashed) one.
- Fix the '{:p}' forwarding implementation, which could print the
address of a temporary stack variable.
- 'time' module:
- Make 'Delta' generic over its time unit, with a default unit of
nanoseconds ('Nsec'), preserving the existing behavior. Then, add
a 'Jiffy' time unit.
- Add the 'Delta::as_millis_ceil()' method.
- Fix 'as_micros_ceil()' rounding near 'i64::MAX', which could
yield a result one microsecond too small.
- 'sync' module:
- Implement 'ForeignOwnable' for 'ARef<T>', allowing C code to own
an 'ARef<T>'.
- Add a safe abstraction for 'rcu_barrier()'.
- 'error' module: add all of the remaining error codes, except the
deprecated compatibility aliases.
- 'bug' module:
- Fix build error on UML in 'warn_on!' for callers from within
the 'kernel' crate.
- Fix future 'dead_code' warning on arm and loongarch64 and under
'CONFIG_BUG=n' in 'warn_on!', which would trigger with the
upcoming SRCU abstractions.
- Fix future build error in 'rusttest' on cross-compilation cases,
which would trigger when 'warn_on!' has callers inside the
'kernel' crate.
- 'bitfield' module: fix build error for the upcoming support for
Rust's GCC backend ('rustc_codegen_gcc') by always inlining a couple
conversions used in tests.
'pin-init' crate:
- User-visible changes:
- Merge the '__pinned_init' and '__init' methods and make 'Init'
a marker trait.
- Introduce public APIs 'raw_init' and 'raw_try_init' to prevent
users from needing to invoke the internal
'__pinned_init'/'__init' methods.
- Emit errors for duplicate '#[pin]' attributes.
- Link 'Zeroable::zeroed' and 'pin_init::zeroed' in documentation.
- Other changes:
- Fix unwind safety issues.
- Clean up lint 'allow' and 'expect's.
- Overhaul '#[cfg]' handling to pave the way for tuple structs and
self-referential structs.
- Mark many functions as '#[inline]' for better codegen with '-C
opt-level=s' ('CC_OPTIMIZE_FOR_SIZE').
'MAINTAINERS':
- Update 'MODULE SUPPORT' to cover the new 'module' module.
And some other fixes, cleanups and improvements.

let b: u64 = 4096usize.into_safe_cast();
- Add 'Bounded::shr_exact' method in the vein of 'try_shrink'
which shifts a bounded right only if it loses no set bits
- Fix unsoundness issue in the 'Bounded::shr' method by
rejecting, at compile-time, shifts of at least the type's bit
width
- 'fmt' module:
- Route '{:p}' raw pointer formatting through the kernel's hashed
'%p' format to prevent address leaks, including support for
width and padding. Include tests for both 'no_hash_pointers'
case and the default (hashed) one
- Fix the '{:p}' forwarding implementation, which could print the
address of a temporary stack variable
- 'time' module:
- Make 'Delta' generic over its time unit, with a default unit of
nanoseconds ('Nsec'), preserving the existing behavior. Then,
add a 'Jiffy' time unit
- Add the 'Delta::as_millis_ceil()' method
- Fix 'as_micros_ceil()' rounding near 'i64::MAX', which could
yield a result one microsecond too small
- 'sync' module:
- Implement 'ForeignOwnable' for 'ARef<T>', allowing C code to
own an 'ARef<T>'
- Add a safe abstraction for 'rcu_barrier()'
- 'error' module: add all of the remaining error codes, except the
deprecated compatibility aliases
- 'bug' module:
- Fix build error on UML in 'warn_on!' for callers from within
the 'kernel' crate
- Fix future 'dead_code' warning on arm and loongarch64 and under
'CONFIG_BUG=n' in 'warn_on!', which would trigger with the
upcoming SRCU abstractions
- Fix future build error in 'rusttest' on cross-compilation
cases, which would trigger when 'warn_on!' has callers inside
the 'kernel' crate
- 'bitfield' module: fix build error for the upcoming support for
Rust's GCC backend ('rustc_codegen_gcc') by always inlining a
couple conversions used in tests
'pin-init' crate:
- User-visible changes:
- Merge the '__pinned_init' and '__init' methods and make 'Init'
a marker trait
- Introduce public APIs 'raw_init' and 'raw_try_init' to prevent
users from needing to invoke the internal '__pinned_init' and
'__init' methods
- Emit errors for duplicate '#[pin]' attributes
- Link 'Zeroable::zeroed' and 'pin_init::zeroed' in documentation
- Other changes:
- Fix unwind safety issues
- Clean up lint 'allow' and 'expect's
- Overhaul '#[cfg]' handling to pave the way for tuple structs
and self-referential structs
- Mark many functions as '#[inline]' for better codegen with '-C
opt-level=s' ('CC_OPTIMIZE_FOR_SIZE')
'MAINTAINERS':
- Update 'MODULE SUPPORT' to cover the new 'module' module
And some other fixes, cleanups and improvements"
