Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas: - arm64 perf: DDR PMU driver for Alibaba's T-Head Yitian 710 SoC, SVE vector granule register added to the user regs together with SVE perf extensions documentation. - SVE updates: add HWCAP for SVE EBF16, update the SVE ABI documentation to match the actual kernel behaviour (zeroing the registers on syscall rather than "zeroed or preserved" previously). - More conversions to automatic system registers generation. - vDSO: use self-synchronising virtual counter access in gettimeofday() if the architecture supports it. - arm64 stacktrace cleanups and improvements. - arm64 atomics improvements: always inline assembly, remove LL/SC trampolines. - Improve the reporting of EL1 exceptions: rework BTI and FPAC exception handling, better EL1 undefs reporting. - Cortex-A510 erratum 2658417: remove BF16 support due to incorrect result. - arm64 defconfig updates: build CoreSight as a module, enable options necessary for docker, memory hotplug/hotremove, enable all PMUs provided by Arm. - arm64 ptrace() support for TPIDR2_EL0 (register provided with the SME extensions). - arm64 ftraces updates/fixes: fix module PLTs with mcount, remove unused function. - kselftest updates for arm64: simple HWCAP validation, FP stress test improvements, validation of ZA regs in signal handlers, include larger SVE and SME vector lengths in signal tests, various cleanups. - arm64 alternatives (code patching) improvements to robustness and consistency: replace cpucap static branches with equivalent alternatives, associate callback alternatives with a cpucap. - Miscellaneous updates: optimise kprobe performance of patching single-step slots, simplify uaccess_mask_ptr(), move MTE registers initialisation to C, support huge vmalloc() mappings, run softirqs on the per-CPU IRQ stack, compat (arm32) misalignment fixups for multiword accesses. * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (126 commits) arm64: alternatives: Use vdso/bits.h instead of linux/bits.h arm64/kprobe: Optimize the performance of patching single-step slot arm64: defconfig: Add Coresight as module kselftest/arm64: Handle EINTR while reading data from children kselftest/arm64: Flag fp-stress as exiting when we begin finishing up kselftest/arm64: Don't repeat termination handler for fp-stress ARM64: reloc_test: add __init/__exit annotations to module init/exit funcs arm64/mm: fold check for KFENCE into can_set_direct_map() arm64: ftrace: fix module PLTs with mcount arm64: module: Remove unused plt_entry_is_initialized() arm64: module: Make plt_equals_entry() static arm64: fix the build with binutils 2.27 kselftest/arm64: Don't enable v8.5 for MTE selftest builds arm64: uaccess: simplify uaccess_mask_ptr() arm64: asm/perf_regs.h: Avoid C++-style comment in UAPI header kselftest/arm64: Fix typo in hwcap check arm64: mte: move register initialization to C arm64: mm: handle ARM64_KERNEL_USES_PMD_MAPS in vmemmap_populate() arm64: dma: Drop cache invalidation from arch_dma_prep_coherent() arm64/sve: Add Perf extensions documentation ...
