Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon: "The two main things to note are: (1) The bulk of the diffstat is us reverting a horrible bodge we had in place to ease the merging of maple tree during the merge window (which turned out not to be needed, but anyway) (2) The TLB invalidation fix is done in core code, as suggested by (and Acked-by) Peter. Summary: - Revert temporary bodge in MTE coredumping to ease maple tree integration - Fix stack frame size warning reported with 64k pages - Fix stop_machine() race with instruction text patching - Ensure alternatives patching routines are not instrumented - Enable Spectre-BHB mitigation for Cortex-A78AE - Fix hugetlb TLB invalidation when contiguous hint is used - Minor perf driver fixes - Fix some typos" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: perf/imx_ddr: Fix undefined behavior due to shift overflowing the constant arm64: Add part number for Arm Cortex-A78AE arm64: patch_text: Fixup last cpu should be master tlb: hugetlb: Add more sizes to tlb_remove_huge_tlb_entry arm64: alternatives: mark patch_alternative() as `noinstr` perf: MARVELL_CN10K_DDR_PMU should depend on ARCH_THUNDER perf: qcom_l2_pmu: fix an incorrect NULL check on list iterator arm64: Fix comments in macro __init_el2_gicv3 arm64: fix typos in comments arch/arm64: Fix topology initialization for core scheduling arm64: mte: Fix the stack frame size warning in mte_dump_tag_range() Revert "arm64: Change elfcore for_each_mte_vma() to use VMA iterator"
