Thank you!
Hi Linus, Please pull the arm64 updates for 5.17. A patch from Peter Z making ARCH_STACKWALK independent of STACKTRACE touches x86, s390 and riscv. The perf changes also touch kernel/events/core.c and arch/x86/events/. I generated the diffstat manually by merging against current mainline (75acfdb6fd92), otherwise it's all over the place since I had to merge the arm64 for-next/fixes (based on -rc1) for a BTI fix dependency into for-next/core (based on -rc3). Thanks, Catalin The following changes since commit 35b6b28e69985eafb20b3b2c7bd6eca452b56b53: arm64: ftrace: add missing BTIs (2021-12-02 10:18:32 +0000) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux tags/arm64-upstream for you to fetch changes up to 945409a6ef442cfe5f2f14e5626d4306d53100f0: Merge branches 'for-next/misc', 'for-next/cache-ops-dzp', 'for-next/stacktrace', 'for-next/xor-neon', 'for-next/kasan', 'for-next/armv8_7-fp', 'for-next/atomics', 'for-next/bti', 'for-next/sve', 'for-next/kselftest' and 'for-next/kcsan', remote-tracking branch 'arm64/for-next/perf' into for-next/core (2022-01-05 18:14:32 +0000) ---------------------------------------------------------------- arm64 updates for 5.17: - KCSAN enabled for arm64. - Additional kselftests to exercise the syscall ABI w.r.t. SVE/FPSIMD. - Some more SVE clean-ups and refactoring in preparation for SME support (scalable matrix extensions). - BTI clean-ups (SYM_FUNC macros etc.) - arm64 atomics clean-up and codegen improvements. - HWCAPs for FEAT_AFP (alternate floating point behaviour) and FEAT_RPRESS (increased precision of reciprocal estimate and reciprocal square root estimate). - Use SHA3 instructions to speed-up XOR. - arm64 unwind code refactoring/unification. - Avoid DC (data cache maintenance) instructions when DCZID_EL0.DZP == 1 (potentially set by a hypervisor; user-space already does this). - Perf updates for arm64: support for CI-700, HiSilicon PCIe PMU, Marvell CN10K LLC-TAD PMU, miscellaneous clean-ups. - Other fixes and clean-ups; highlights: fix the handling of erratum 1418040, correct the calculation of the nomap region boundaries, introduce io_stop_wc() mapped to the new DGH instruction (data gathering hint). ---------------------------------------------------------------- Ard Biesheuvel (1): arm64/xor: use EOR3 instructions when available Bhaskara Budiredla (2): drivers: perf: Add LLC-TAD perf counter support dt-bindings: perf: Add YAML schemas for Marvell CN10K LLC-TAD pmu bindings Catalin Marinas (3): Merge 'arm64/for-next/fixes' into for-next/bti arm64: Ensure that the 'bti' macro is defined where linkage.h is included Merge branches 'for-next/misc', 'for-next/cache-ops-dzp', 'for-next/stacktrace', 'for-next/xor-neon', 'for-next/kasan', 'for-next/armv8_7-fp', 'for-next/atomics', 'for-next/bti', 'for-next/sve', 'for-next/kselftest' and 'for-next/kcsan', remote-tracking branch 'arm64/for-next/perf' into for-next/core D Scott Phillips (1): arm64: errata: Fix exec handling in erratum 1418040 workaround Dan Carpenter (1): drivers: perf: marvell_cn10k: fix an IS_ERR() vs NULL check Florian Fainelli (1): arm64: entry: Use SDEI event constants Guilherme G.
