The only non-trivial change (in terms of the diffstat) is fixing our SVE ptrace API for big-endian machines, but the majority of this is actually the addition of much-needed comments and updates to the documentation to try to avoid this mess biting us again in future. There are still a couple of small things on the horizon, but nothing major at this point. Please pull. Thanks, Will --->8 The following changes since commit ebcc5928c5d925b1c8d968d9c89cdb0d0186db17: arm64: Silence gcc warnings about arch ABI drift (2019-06-06 13:28:45 +0100) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git tags/arm64-fixes for you to fetch changes up to 41040cf7c5f0f26c368bc5d3016fed3a9ca6dba4: arm64/sve: Fix missing SVE/FPSIMD endianness conversions (2019-06-13 10:07:19 +0100) ---------------------------------------------------------------- arm64 fixes for -rc5 - Fix broken SVE ptrace API when running in a big-endian configuration - Fix performance regression due to off-by-one in TLBI range checking - Fix build regression when using Clang ---------------------------------------------------------------- Dave Martin (1): arm64/sve: Fix missing SVE/FPSIMD endianness conversions Nathan Chancellor (1): arm64: Don't unconditionally add -Wno-psabi to KBUILD_CFLAGS Will Deacon (1): arm64: tlbflush: Ensure start/end of address range are aligned to stride Documentation/arm64/sve.txt | 16 ++++++++++++ arch/arm64/Makefile | 2 +- arch/arm64/include/asm/tlbflush.h | 3 +++ arch/arm64/include/uapi/asm/kvm.h | 7 ++++++ arch/arm64/include/uapi/asm/ptrace.h | 4 +++ arch/arm64/include/uapi/asm/sigcontext.h | 14 +++++++++++ arch/arm64/kernel/fpsimd.c | 42 +++++++++++++++++++++++++------- 7 files changed, 78 insertions(+), 10 deletions(-)
