# 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() #
