It's almost entirely contained within arch/arm64/, drivers/perf/ and tools/testing/ with a few additional changes in drivers/ due to more automatic sysreg definitions generation. There is a trivial conflict with current mainline removing the '__nocfi' annotation while the arm64 tree makes a pointer const for the same function. I included my merge resolution below. Thanks. The following changes since commit b90cb1053190353cc30f0fef0ef1f378ccc063c5: Linux 6.0-rc3 (2022-08-28 15:05:29 -0700) are available in the Git repository at:

---------------------------------------------------------------- arm64 updates for 6.1: - 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. ---------------------------------------------------------------- Ard
