Pull arm64 updates from Will Deacon:
"I think we have a bit less than usual on the architecture side, but
that's somewhat balanced out by a large crop of perf/PMU driver
updates and extensions to our selftests.

CPU features and system registers:

- Advertise hinted conditional branch support (FEAT_HBC) to userspace

- Avoid false positive "SANITY CHECK" warning when xCR registers
differ outside of the length field

Documentation:

- Fix macro name typo in SME documentation

Entry code:

- Unmask exceptions earlier on the system call entry path

Memory management:

- Don't bother clearing PTE_RDONLY for dirty ptes in pte_wrprotect()
and pte_modify()

Perf and PMU drivers:

- Initial support for Coresight TRBE devices on ACPI systems (the
coresight driver changes will come later)

- Fix hw_breakpoint single-stepping when called from bpf

- Fixes for DDR PMU on i.MX8MP SoC

- Add NUMA-awareness to Hisilicon PCIe PMU driver

- Fix locking dependency issue in Arm DMC620 PMU driver

- Workaround Hisilicon erratum 162001900 in the SMMUv3 PMU driver

- Add support for Arm CMN-700 r3 parts to the CMN PMU driver

- Add support for recent Arm Cortex CPU PMUs

- Update Hisilicon PMU maintainers

Selftests:

- Add a bunch of new features to the hwcap test (JSCVT, PMULL, AES,
SHA1, etc)

- Fix SSVE test to leave streaming-mode after grabbing the signal
context

- Add new test for SVE vector-length changes with SME enabled

Miscellaneous:

- Allow compiler to warn on suspicious looking system register
expressions

- Work around SDEI firmware bug by aborting any running handlers on a
kernel crash

- Fix some harmless warnings when building with W=1

- Remove some unused function declarations

- Other minor fixes and cleanup"

Pull arm64 updates from Catalin Marinas:
"Notable features are user-space support for the memcpy/memset
instructions and the permission indirection extension.

- Support for the Armv8.9 Permission Indirection Extensions. While
this feature doesn't add new functionality, it enables future
support for Guarded Control Stacks (GCS) and Permission Overlays

- User-space support for the Armv8.8 memcpy/memset instructions

- arm64 perf: support the HiSilicon SoC uncore PMU, Arm CMN sysfs
identifier, support for the NXP i.MX9 SoC DDRC PMU, fixes and
cleanups

- Removal of superfluous ISBs on context switch (following
retrospective architecture tightening)

- Decode the ISS2 register during faults for additional information
to help with debugging

- KPTI clean-up/simplification of the trampoline exit code

- Addressing several -Wmissing-prototype warnings

- Kselftest improvements for signal handling and ptrace

- Fix TPIDR2_EL0 restoring on sigreturn

- Clean-up, robustness improvements of the module allocation code

- More sysreg conversions to the automatic register/bitfields
generation

Pull scheduler updates from Ingo Molnar:

- Improve the scalability of the CFS bandwidth unthrottling logic with
large number of CPUs.

- Fix & rework various cpuidle routines, simplify interaction with the
generic scheduler code. Add __cpuidle methods as noinstr to objtool's
noinstr detection and fix boatloads of cpuidle bugs & quirks.

- Add new ABI: introduce MEMBARRIER_CMD_GET_REGISTRATIONS, to query
previously issued registrations.

- Limit scheduler slice duration to the sysctl_sched_latency period, to
improve scheduling granularity with a large number of SCHED_IDLE
tasks.

- Debuggability enhancement on sys_exit(): warn about disabled IRQs,
but also enable them to prevent a cascade of followup problems and
repeat warnings.

- Fix the rescheduling logic in prio_changed_dl().

- Micro-optimize cpufreq and sched-util methods.

- Micro-optimize ttwu_runnable()

- Micro-optimize the idle-scanning in update_numa_stats(),
select_idle_capacity() and steal_cookie_task().

- Update the RSEQ code & self-tests

| WARNING: suspicious RCU usage
| -----------------------------
| include/trace/events/ipi.h:19 suspicious rcu_dereference_check() usage!

Fix cpuidle on ARM64:

- ... by introducing a new 'is_rcu' flag to the cpuidle helpers & make
ARM64 use it, as ARM64 wants to keep RCU active longer and wants to
do the ct_cpuidle_enter()/exit() dance itself.

- Also update the PSCI driver accordingly.

- This also removes the last known RCU_NONIDLE() user as a bonus.
