Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon: "There's the usual summary below, but the highlights are support for the Armv8.6 timer extensions, KASAN support for asymmetric MTE, the ability to kexec() with the MMU enabled and a second attempt at switching to the generic pfn_valid() implementation. Summary: - Support for the Arm8.6 timer extensions, including a self-synchronising view of the system registers to elide some expensive ISB instructions. - Exception table cleanup and rework so that the fixup handlers appear correctly in backtraces. - A handful of miscellaneous changes, the main one being selection of CONFIG_HAVE_POSIX_CPU_TIMERS_TASK_WORK. - More mm and pgtable cleanups. - KASAN support for "asymmetric" MTE, where tag faults are reported synchronously for loads (via an exception) and asynchronously for stores (via a register). - Support for leaving the MMU enabled during kexec relocation, which significantly speeds up the operation. - Minor improvements to our perf PMU drivers. - Improvements to the compat vDSO build system, particularly when building with LLVM=1. - Preparatory work for handling some Coresight TRBE tracing errata. - Cleanup and refactoring of the SVE code to pave the way for SME support in future. - Ensure SCS pages are unpoisoned immediately prior to freeing them when KASAN is enabled for the vmalloc area. - Try moving to the generic pfn_valid() implementation again now that the DMA mapping issue from last time has been resolved. - Numerous improvements and additions to our FPSIMD and SVE selftests" [ armv8.6 timer updates were in a shared branch and already came in through -tip in the timer pull - Linus ] * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (85 commits) arm64: Select POSIX_CPU_TIMERS_TASK_WORK arm64: Document boot requirements for FEAT_SME_FA64 arm64/sve: Fix warnings when SVE is disabled arm64/sve: Add stub for sve_max_virtualisable_vl() arm64: errata: Add detection for TRBE write to out-of-range arm64: errata: Add workaround for TSB flush failures arm64: errata: Add detection for TRBE overwrite in FILL mode arm64: Add Neoverse-N2, Cortex-A710 CPU part definition selftests: arm64: Factor out utility functions for assembly FP tests arm64: vmlinux.lds.S: remove `.fixup` section arm64: extable: add load_unaligned_zeropad() handler arm64: extable: add a dedicated uaccess handler arm64: extable: add `type` and `data` fields arm64: extable: use `ex` for `exception_table_entry` arm64: extable: make fixup_exception() return bool arm64: extable: consolidate definitions arm64: gpr-num: support W registers arm64: factor out GPR numbering helpers arm64: kvm: use kvm_exception_table_entry arm64: lib: __arch_copy_to_user(): fold fixups into body ...
