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. -----BEGIN PGP SIGNATURE----- iQFEBAABCgAuFiEEPxTL6PPUbjXGY88ct6xw3ITBYzQFAmbkVNEQHHdpbGxAa2Vy bmVsLm9yZwAKCRC3rHDchMFjNKeIB/9YtbN7JMgsXktM94GP03r3tlFF36Y1S51S +zdDZclAVZCTCZN+PaFeAZ/+ah2EQYrY6rtDoHUSEMQdF9kH+ycuIPDTwaJ4Qkam QKXMpAgtY/4yf2rX4lhDF8rEvkhLDsu7oGDhqUZQsA33GrMBHfgA3oqpYwlVjvGq gkm7olTo9LdWAxkPpnjGrjB6Mv5Dq8dJRhW+0Q5AntI5zx3RdYGJZA9GUSzyYCCt FIYOtMmWPkQ0kKxIVxOxAOm/ubhfyCs2sjSfkaa3vtvtt+Yjye1Xd81rFciIbPgP QlK/Mes2kBZmjhkeus8guLI5Vi7tx3DQMkNqLXkHAAzOoC4oConE =6osL -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Will Deacon: "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.
