Pull sysctl updates from Joel Granados:
- Move sysctls out of the kern_table array
This is the final move of ctl_tables into their respective
subsystems. Only 5 (out of the original 50) will remain in
kernel/sysctl.c file; these handle either sysctl or common arch
variables.
By decentralizing sysctl registrations, subsystem maintainers regain
control over their sysctl interfaces, improving maintainability and
reducing the likelihood of merge conflicts.
- docs: Remove false positives from check-sysctl-docs
Stopped falsely identifying sysctls as undocumented or unimplemented
in the check-sysctl-docs script. This script can now be used to
automatically identify if documentation is missing.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas:
"A quick summary: perf support for Branch Record Buffer Extensions
(BRBE), typical PMU hardware updates, small additions to MTE for
store-only tag checking and exposing non-address bits to signal
handlers, HAVE_LIVEPATCH enabled on arm64, VMAP_STACK forced on.
There is also a TLBI optimisation on hardware that does not require
break-before-make when changing the user PTEs between contiguous and
non-contiguous.
More details:
Perf and PMU updates:
- Add support for new (v3) Hisilicon SLLC and DDRC PMUs
- Add support for Arm-NI PMU integrations that share interrupts
between clock domains within a given instance
- Allow SPE to be configured with a lower sample period than the
minimum recommendation advertised by PMSIDR_EL1.Interval
- Add suppport for Arm's "Branch Record Buffer Extension" (BRBE)
- Adjust the perf watchdog period according to cpu frequency changes
- Minor driver fixes and cleanups

slices duration, for better handling of lag in the fair scheduler
(Vincent Guittot)
- Clean up and standardize #if/#else/#endif markers throughout the
entire scheduler code base (Ingo Molnar)
- Make SMP unconditional: build the SMP scheduler's data structures
and logic on UP kernel too, even though they are not used, to
simplify the scheduler and remove around 200 #ifdef/[#else]/#endif
blocks from the scheduler (Ingo Molnar)

- Remove sched_domain_topology_level::flags to simplify the code
(Prateek Nayak)
- Simplify and clean up build_sched_topology() (Li Chen)
- Optimize build_sched_topology() on large machines (Li Chen)
Real-time scheduling:
- Add initial version of proxy execution: a mechanism for
mutex-owning tasks to inherit the scheduling context of higher
priority waiters.
Currently limited to a single runqueue and conditional on
CONFIG_EXPERT, and other limitations (John Stultz, Peter Zijlstra,
Valentin Schneider)
- Deadline scheduler (Juri Lelli):

- Fix scalability regression by implementing less agressive
dl_server handling (Peter Zijlstra)
PSI:
- Improve scalability by optimizing psi_group_change() cpu_clock()
usage (Peter Zijlstra)
Rust changes:
- Make Task, CondVar and PollCondVar methods inline to avoid
unnecessary function calls (Kunwu Chan, Panagiotis Foliadis)
- Add might_sleep() support for Rust code: Rust's "#[track_caller]"
mechanism is used so that Rust's might_sleep() doesn't need to be
defined as a macro (Fujita Tomonori)
- Introduce file_from_location() (Boqun Feng)

compiler_types: Provide __no_kstack_erase to disable coverage only on Clang
In order to support Clang's stack depth tracking (for Linux's kstack_erase
feature), the coverage sanitizer needed to be disabled for __init (and
__head) section code. Doing this universally (i.e. for GCC too) created
a number of unexpected problems, ranging from changes to inlining logic
to failures to DCE code on earlier GCC versions.
Since this change is only needed for Clang, specialize it so that GCC
doesn't see the change as it isn't needed there (the GCC implementation
of kstack_erase uses a GCC plugin that removes stack depth tracking
instrumentation from __init sections during a late pass in the IR).
Successfully build and boot tested with GCC 12 and Clang 22.

Merge tag 'timers-ptp-2025-07-27' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timekeeping and VDSO updates from Thomas Gleixner: - Introduce support for auxiliary timekeepers PTP clocks can be disconnected from the universal CLOCK_TAI reality for various reasons including regularatory requirements for functional safety redundancy. The kernel so far only supports a single notion of time, which means that all clocks are correlated in frequency and only differ by offset to each other. Access to non-correlated PTP clocks has been available so far only through the file descriptor based "POSIX clock IDs", which are subject to locking and have to go all the way out to the hardware. The access is not only horribly slow, as it has to go all the way out to the NIC/PTP hardware, but that also prevents the kernel to read the time of such clocks e.g. from the network stack, where it is required for TSN networking both on the transmit and receive side unless the hardware provides offloading. The auxiliary clocks provide a mechanism to support arbitrary clocks which are not correlated to the system clock. This is not restricted to the PTP use case on purpose as there is no kernel side association of these clocks to a particular PTP device because that's a pure user space configuration decision. Having them independent allows to utilize them for other purposes and also enables them to be tested without hardware dependencies. To avoid pointless overhead these clocks have to be enabled individualy via a new sysfs interface to reduce the overhead to a single compare in the hotpath if they are enabled at the Kconfig level at all. These clocks utilize the existing timekeeping/NTP infrastructures, which has been made possible over the recent releases by incrementaly converting these infrastructures over from a single static instance to a multi-instance pointer based implementation without any performance regression reported. The auxiliary clocks provide the same "emulation" of a "correct" clock as the existing CLOCK_* variants do with an independent instance of data and provide the same steering mechanism through the existing sys_clock_adjtime() interface, which has been confirmed to work by the chronyd(8) maintainer. That allows to provide lockless kernel internal and VDSO support so that applications and kernel internal functionalities can access these clocks without restrictions and at the same performance as the existing system clocks. - Avoid double notifications in the adjtimex() syscall. Not a big issue, but a trivial to avoid latency source. * tag 'timers-ptp-2025-07-27' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (39 commits) vdso/gettimeofday: Add support for auxiliary clocks vdso/vsyscall: Update auxiliary clock data in the datapage vdso: Introduce aux_clock_resolution_ns() vdso/gettimeofday: Introduce vdso_get_timestamp() vdso/gettimeofday: Introduce vdso_set_timespec() vdso/gettimeofday: Introduce vdso_clockid_valid() vdso/gettimeofday: Return bool from clock_gettime() helpers vdso/gettimeofday: Return bool from clock_getres() helpers vdso/helpers: Add helpers for seqlocks of single vdso_clock vdso/vsyscall: Split up __arch_update_vsyscall() into __arch_update_vdso_clock() vdso/vsyscall: Introduce a helper to fill clock configurations timekeeping: Remove the temporary CLOCK_AUX workaround timekeeping: Provide ktime_get_clock_ts64() timekeeping: Provide interface to control auxiliary clocks timekeeping: Provide update for auxiliary timekeepers timekeeping: Provide adjtimex() for auxiliary clocks timekeeping: Prepare do_adtimex() for auxiliary clocks timekeeping: Make do_adjtimex() reusable timekeeping: Add auxiliary clock support to __timekeeping_inject_offset() timekeeping: Make timekeeping_inject_offset() reusable ... |

Pull irq updates from Thomas Gleixner: - Prevent a interrupt migration related live lock in handle_edge_irq() If the interrupt affinity is moved to a new target CPU and the interrupt is currently handled on the previous target CPU for edge type interrupts the handler might get stuck on the previous target for a long time, which causes both involved CPUs to waste cycles and eventually run into a soft-lockup situation. Solve this by checking whether the interrupt is redirected to a new target CPU and if the interrupt is handled on that new target CPU, busy wait for completion instead of masking it and sending the pending but which would cause the old CPU to re-run the handler and in the worst case repeating this excercise for a long time. This only works on architectures which use single CPU interrupt targets, but that's so far the only ones where this behaviour has been observed. - Add a kunit test for interrupt disable depth counts The nested interrupt disable depth has been an issue in the past especially vs. free_irq(), interrupt shutdown and CPU hotplug and their interactions. The test exercises the combinations of these scenarios and checks for correctness. * tag 'irq-core-2025-07-27' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: genirq: Prevent migration live lock in handle_edge_irq() genirq: Split up irq_pm_check_wakeup() genirq: Move irq_wait_for_poll() to call site genirq: Remove pointless local variable genirq: Add kunit tests for depth counts |
