Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
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 - CPU capabilities handling cleanup - Arm documentation updates: ACPI, ptdump" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (124 commits) kselftest/arm64: Add a test case for TPIDR2 restore arm64/signal: Restore TPIDR2 register rather than memory state arm64: alternatives: make clean_dcache_range_nopatch() noinstr-safe Documentation/arm64: Add ptdump documentation arm64: hibernate: remove WARN_ON in save_processor_state kselftest/arm64: Log signal code and address for unexpected signals docs: perf: Fix warning from 'make htmldocs' in hisi-pmu.rst arm64/fpsimd: Exit streaming mode when flushing tasks docs: perf: Add new description for HiSilicon UC PMU drivers/perf: hisi: Add support for HiSilicon UC PMU driver drivers/perf: hisi: Add support for HiSilicon H60PA and PAv3 PMU driver perf: arm_cspmu: Add missing MODULE_DEVICE_TABLE perf/arm-cmn: Add sysfs identifier perf/arm-cmn: Revamp model detection perf/arm_dmc620: Add cpumask arm64: mm: fix VA-range sanity check arm64/mm: remove now-superfluous ISBs from TTBR writes Documentation/arm64: Update ACPI tables from BBR Documentation/arm64: Update references in arm-acpi Documentation/arm64: Update ARM and arch reference ...
