Most of these are fixes that came in during the merge window, with the exception of the HAVE_MOVE_PMD mremap() speed-up which we discussed back in 2018 and somehow forgot to enable upstream [1]. Anyway, usual summary in the tag. Marc Zyngier managed to get his paws on a Falkor system and offered a Tested-by on the Spectre-v2 mitigation patch, but it came in after I'd applied the thing. Please pull. Thanks, Will [1] https://lore.kernel.org/kvmarm/20181108181201.88826-3-joelaf@google.com/ --->8 The following changes since commit d13027bb35e089bc1bb9f19c4976decf32a09b97: Revert "arm64: initialize per-cpu offsets earlier" (2020-10-09 11:24:17 +0100) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git tags/arm64-upstream for you to fetch changes up to 66dd3474702aa98d5844367e1577cdad78ef7c65: arm64: proton-pack: Update comment to reflect new function name (2020-10-21 11:07:27 +0100) ---------------------------------------------------------------- More arm64 updates for 5.10 - Improve performance of Spectre-v2 mitigation on Falkor CPUs (if you're lucky enough to have one) - Select HAVE_MOVE_PMD. This has been shown to improve mremap() performance, which is used heavily by the Android runtime GC, and it seems we forgot to enable this upstream back in 2018. - Ensure linker flags are consistent between LLVM and BFD - Fix stale comment in Spectre mitigation rework - Fix broken copyright header - Fix KASLR randomisation of the linear map - Prevent arm64-specific prctl()s from compat tasks (return -EINVAL) ---------------------------------------------------------------- Ard Biesheuvel (1): arm64: mm: use single quantity to represent the PA to VA translation Kalesh Singh (1): arm64: mremap speedup - Enable HAVE_MOVE_PMD Nick Desaulniers (1): arm64: link with -z norelro regardless of CONFIG_RELOCATABLE Palmer Dabbelt (1): arm64: Fix a broken copyright header in gen_vdso_offsets.sh Peter Collingbourne (1): arm64: reject prctl(PR_PAC_RESET_KEYS) on compat tasks Stephen Boyd (1): arm64: proton-pack: Update comment to reflect new function name Will Deacon (1): arm64: spectre-v2: Favour CPU-specific mitigation at EL2 arch/arm64/Kconfig | 1 + arch/arm64/Makefile | 4 +-- arch/arm64/include/asm/memory.h | 5 ++-- arch/arm64/include/asm/pgtable.h | 4 +-- arch/arm64/kernel/fpsimd.c | 4 +-- arch/arm64/kernel/pointer_auth.c | 4 +++ arch/arm64/kernel/proton-pack.c | 40 ++++++++++++++---------------- arch/arm64/kernel/vdso/gen_vdso_offsets.sh | 2 +- arch/arm64/mm/init.c | 30 ++++++++-------------- 9 files changed, 43 insertions(+), 51 deletions(-)
