Subject: [GIT PULL] arm64 updates for 6.12
Hi Linus,
Like a bunch of folks, I'll be living off conference coffee and canapes
for the next week or so, so here's the arm64 pull request for 6.12
before the chaos descends and the malnutrition sets in.
There's the usual summary in the tag, but the highlights are support for
Arm's "Permission Overlay Extension" using memory protection keys,
support for running as a protected guest on Android as well as perf
support for a bunch of new interconnect PMUs.
There's a trivial conflict with the kvmarm tree which was resolved in
linux-next as per [1]. Any issues, just yell.
Please pull,
Will

Merge branch 'for-next/timers' into for-next/core (2024-09-12 13:44:03 +0100)
----------------------------------------------------------------
arm64 updates for 6.12
ACPI:
* Enable PMCG erratum workaround for HiSilicon HIP10 and 11 platforms.
* Ensure arm64-specific IORT header is covered by MAINTAINERS.
CPU Errata:
* Enable workaround for hardware access/dirty issue on Ampere-1A cores.
Memory management:
* Define PHYSMEM_END to fix a crash in the amdgpu driver.
* Avoid tripping over invalid kernel mappings on the kexec() path.
* Userspace support for the Permission Overlay Extension (POE) using
protection keys.
Perf and PMUs:
* Add support for the "fixed instruction counter" extension in the CPU
PMU architecture.
* Extend and fix the event encodings for Apple's M1 CPU PMU.
* Allow LSM hooks to decide on SPE permissions for physical profiling.
* Add support for the CMN S3 and NI-700 PMUs.
Confidential Computing:
* Add support for booting an arm64 kernel as a protected guest under
Android's "Protected KVM" (pKVM) hypervisor.
Selftests:
* Fix vector length issues in the SVE/SME sigreturn tests
* Fix build warning in the ptrace tests.
Timers:
* Add support for PR_{G,S}ET_TSC so that 'rr' can deal with
non-determinism arising from the architected counter.
Miscellaneous:
* Rework our IPI-based CPU stopping code to try NMIs if regular IPIs
don't succeed.
* Minor fixes and cleanups.
