Merge tag 'soc-arm-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC platform updates from Arnd Bergmann:
"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"

"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

"There are two things in here of note. First, there are fixes to reduce

but the code did end up better for it.

Merge tag 'timers-core-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer and timekeeping core updates from Thomas Gleixner: - 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 hard 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 * tag 'timers-core-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (58 commits) selftests: timers: nsleep-lat: Check all calls to clock_nanosleep() and clock_gettime() selftests: timers: nsleep-lat: Reuse kselftest error numbers selftests: timers: nsleep-lat: Explicitly list the tested clocks selftests: timers: nsleep-lat: Use NSEC_PER_MSEC define for unreasonable latency selftests: timers: nanosleep: Report each test separately selftests: timers: nanosleep: Explicitly handle timer_delete() failure selftests: timers: nanosleep: Move all single clock tests out of the loop in main() selftests: timers: nanosleep: Reuse kselftest error numbers selftests: timers: nanosleep: Explicitly list the tested clocks selftests: timers: nanosleep: Drop output alignment selftests: timers: Use clock_name() and constants from clock-helpers.h selftests: Add clock-helpers.h timer_list: Use ktime_t over nanoseconds timer_list: Use standard 'long long' format placeholders hrtimer: Add a lockdep assertion to hrtimer_update_base() timekeeping: Use u32 for clock_was_set_seq timekeeping: Rename clockid_aux_valid() to clockid_is_aux_clock() hrtimer: Account nr_retries on recovered interrupt retries timers/itimer: Zero-init old itimerval before copy to userspace nohz: Replace dead select with choice default ... |

Pull SMP core updates from Thomas Gleixner: - 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 * tag 'smp-core-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: scftorture: Remove preempt_disable() in scftorture_invoke_one() smp: Remove preempt_disable() from on_each_cpu_cond_mask() smp: Remove preempt_disable() from smp_call_function() smp: Enable preemption early in smp_call_function_many_cond() smp: Alloc percpu csd data in smpcfd_prepare_cpu() only once smp: Use task-local IPI cpumask in smp_call_function_many_cond() smp: Refactor remote CPU selection in smp_call_function_any() smp: Enable preemption early in smp_call_function_single() smp: Disable preemption explicitly in __csd_lock_wait() cpu/hotplug: Remove CPUHP_AP_ARM_CORESIGHT_CTI_STARTING smp: Use release stores for csd_lock_record() state |

Pull generic entry code updates from Thomas Gleixner: - 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. * tag 'core-entry-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (23 commits) entry, treewide: Make syscall_enter_from_user_mode[_work]() indicate syscall execution entry: Make return type of syscall_trace_enter() bool entry: Rework trace_syscall_enter() entry: Rework syscall_audit_enter() syscall_user_dispatch: Introduce ARCH_SUPPORTS_SYSCALL_USER_DISPATCH entry: Fix seccomp bypass after ptrace with TSYNC x86/entry: Simplify the syscall number logic x86/entry: Get rid of the sys_ni_syscall() indirection x86/entry: Make syscall functions static ptrace, treewide: Rename ptrace_report_syscall_entry() to ptrace_report_syscall_permit_entry() seccomp, treewide: Rename and convert __secure_computing() to return boolean entry: Use syscall number instead of rereading it entry: Remove syscall_enter_from_user_mode() x86/syscall: Use [syscall_]enter_from_user_mode_randomize_stack() s390/syscall: Use enter_from_user_mode_randomize_stack() riscv/syscall: Use syscall_enter_from_user_mode_randomize_stack() powerpc/syscall: Use syscall_enter_from_user_mode_randomize_stack() loongarch/syscall: Use syscall_enter_from_user_mode_randomize_stack() entry: Provide [syscall_]enter_from_user_mode_randomize_stack() randomize_kstack: Provide add_random_kstack_offset_irqsoff() ... |

Merge tag 'rust-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux
Pull Rust updates from Miguel Ojeda:
"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' 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"

Pull ACPI support updates from Rafael Wysocki:
"The most significant change here is the elimination of struct
acpi_driver that has no more users in the tree now along with some
documentation related to it, and a follow-up update to set the "no PM"
flag for all ACPI devices that are now only going to play the role of
other devices' "companions" (in analogy with DT nodes).
There is also a significant update of irqchip code related to ACPI
done in order to enable GICv5 IWB ACPI probe ordering detection on
ARM, which involves RISC-V interrupt controller management code
refactoring to extract generic code from it into the common ACPI IRQ
code.
The rest is mostly fixes, including some fallout of the _OSC handling
rework in 7.0, ACPI CPPC library fixes, a workaround for registering
ACPI platform devices with overlapping I/O or memory resources, an
ACPI EC driver fix related to probe deferral on platforms using
HW-reduced ACPI, two ACPI battery driver fixes and a workaround for
handling model numbers with unprintable characters in it, probe error
cleanup and driver unload code path fixes, hardware error reporting
fixes, documentation fixes, and assorted code cleanups all over.
Specifics:
- Eliminate struct acpi_driver whose users have all been converted to
bind to platform devices or auxiliary devices and set the "no power
management" flag for all struct acpi_device objects (Rafael
Wysocki)
- Avoid complaints regarding missing _OSC features on platforms where
OSC_CAPABILITIES_MASK_ERROR is set in _OSC error bits even though
all of the requested features are actually acknowledged (Rafael
Wysocki)
- Avoid printing confusing _OSC messages for non-PCIe host bridges
without _OSC which is a valid configuration (Kazuma Kondo)
- Use correct region struct for BERT region size check and properly
map BERT and CCEL data to their ACPI tables (Thomas Renninger)
- Add acpi_device_clear_deps(), refactor RISC-V interrupt controller
management code to extract generic code from it into the common
ACPI IRQ code, and enable GICv5 IWB ACPI probe ordering detection
on ARM on top of that (Lorenzo Pieralisi)
- Stop using acpi_device_name() in the PNP core, stop setting
acpi_device_name/class() in the Xen variant of the ACPI PAD
(Processor Aggregator Device) driver, and make the Loongarch laptop
driver stop setting acpi_device_class() (Rafael Wysocki)
- Fix issues related to the desired_perf register access in the ACPI
CPPC library and update it to avoid unnecessary overhead (Christian
Loehle)
- Simplify acpi_get_pci_dev() with the help of a mutex guard,
introduce acpi_dev_get_pci_dev() for code that has a struct ACPI
device for which it wants to get the struct pci_dev pointer of the
associated PCI device, and use it in the ACPI video bus driver
(Rafael Wysocki)
- Avoid registering platform devices with resource overlaps in the
ACPI core device enumeration code (Rafael Wysocki)
- Clean up the list of included header files in the NHLT table parser
and validate the table and record lengths in the FPDT parser (Andy
Shevchenko and Pengpeng Hou)
- Unregister the cpufreq notifier on init failure in the ACPI
processor driver (Can Peng)
- Validate MADT IOAPIC entry bounds during IOAPIC hotplug lookup in
the ACPI processor driver (Pengpeng Hou)

code to use correct struct member names to avoid warnings (Randy
Dunlap)

driver (Randy Dunlap)
- Update ACPI fan IDs to follow modern style and clean up header file
inclusions in the ACPI fan driver (Andy Shevchenko)
- Use devm_acpi_install_notify_handler() to replace a custom
open-coded devres-based management of an ACPI notify handler in the
ACPI fan driver (Rafael Wysocki)
- Adjust charging status validation check in the ACPI battery driver
to avoid incorrect status reporting (Rafael Wysocki)
- Merge consecutive battery notifications in the ACPI battery driver
to reduce the pressure on STA, _BST and _BIX/_BIF ACPI control
methods and make that driver use kstrtoul() instead of
sscanf("%lu\n") (Rong Zhang)
- Sanitise model_number in the ACPI battery driver by dropping
unprintable characters (Kate Hsuan)
- Remove a node_set() call that is redundant from
acpi_parse_memory_affinity() (Sang-Heon Jeon)
- Prevent kernel-doc warnings by converting 2 function description
comments to kernel-doc format (Randy Dunlap)

- Introduce helper function acpi_dev_is_video_device() and use it in
the core ACPI device enumeration code, in the ACPI video bus
driver, in the ACPI support code for I2C, in the PCI VGA driver,
and in the x86 platform thinkpad_acpi driver (Andy Shevchenko)
- Add a quirk to use the native backlight on Acer Nitro AN515-46 to
the ACPI video bus driver (Marcos Paulo Medeiros)
- Release PCI device reference after lookup in
video_detect_portege_r100() in the ACPI video bus driver (Yuho
Choi)"
