Subject: [GIT PULL] arm64 updates for 5.17
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

----------------------------------------------------------------
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).
