Hi Linus, Please pull these arm64 fixes for -rc2. The diffstat is a bit spread out thanks to an invasive CPU erratum workaround which missed the merge window and also a bunch of fixes to the recently added MTE selftests.
We're aware of an arm64 kprobes regression and have a tentative fix [1], but I'd like it to sit in -next for a bit before sending it to you for -rc3. Summary in the tag. Cheers, Will [1] https://lore.kernel.org/r/[email protected] --->8 The following changes since commit 3650b228f83adda7e5ee532e2b90429c03f7b9ec: Linux 5.10-rc1 (2020-10-25 15:14:11 -0700) 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 ec9d78070de986ecf581ea204fd322af4d2477ec: arm64: Change .weak to SYM_FUNC_START_WEAK_PI for arch/arm64/lib/mem*.S (2020-10-30 08:32:31 +0000) ---------------------------------------------------------------- arm64 fixes for -rc2 - Fixes to MTE kselftests - Fix return code from KVM Spectre-v2 hypercall - Build fixes for ld.lld and Clang's infamous integrated assembler - Ensure RCU is up and running before we use printk() - Workaround for Cortex-A77 erratum 1508412 - Fix linker warnings from unexpected ELF sections - Ensure PE/COFF sections are 64k aligned ---------------------------------------------------------------- Ard Biesheuvel (3): arm64: vmlinux.lds: account for spurious empty .igot.plt sections arm64: efi: increase EFI PE/COFF header padding to 64 KB module: use hidden visibility for weak symbol references Arnd Bergmann (1): arm64: avoid -Woverride-init warning Catalin Marinas (1): arm64: mte: Document that user PSTATE.TCO is ignored by kernel uaccess Fangrui Song (1): arm64: Change .weak to SYM_FUNC_START_WEAK_PI for arch/arm64/lib/mem*.S Nathan Chancellor (1): arm64: vdso32: Allow ld.lld to properly link the VDSO Qian Cai (1): arm64/smp: Move rcu_cpu_starting() earlier Rob Herring (2): arm64: Add part number for Arm Cortex-A77 arm64: Add workaround for Arm Cortex-A77 erratum 1508412 Stephen Boyd (1): KVM: arm64: ARM_SMCCC_ARCH_WORKAROUND_1 doesn't return SMCCC_RET_NOT_REQUIRED Vincenzo Frascino (6): kselftest/arm64: Fix check_buffer_fill test kselftest/arm64: Fix check_tags_inclusion test kselftest/arm64: Fix check_child_memory test kselftest/arm64: Fix check_mmap_options test kselftest/arm64: Fix check_ksm_options test kselftest/arm64: Fix check_user_mem test Documentation/arm64/memory-tagging-extension.rst | 4 +++- Documentation/arm64/silicon-errata.rst | 2 ++ arch/arm64/Kconfig | 20 +++++++++++++++++++ arch/arm64/include/asm/cache.h | 1 + arch/arm64/include/asm/cpucaps.h | 3 ++- arch/arm64/include/asm/cputype.h | 2 ++ arch/arm64/include/asm/sysreg.h | 9 +++++++++ arch/arm64/kernel/cpu_errata.c | 10 ++++++++++ arch/arm64/kernel/cpuinfo.c | 7 ++++--- arch/arm64/kernel/efi-header.S | 2 +- arch/arm64/kernel/entry.S | 3 +++ arch/arm64/kernel/proton-pack.c | 2 -- arch/arm64/kernel/smp.c | 1 + arch/arm64/kernel/vdso32/Makefile | 23 +++++++++++----------- arch/arm64/kernel/vmlinux.lds.S | 2 +- arch/arm64/kvm/arm.c | 3 ++- arch/arm64/kvm/hyp/include/hyp/switch.h | 21 ++++++++++++-------- arch/arm64/kvm/hyp/include/hyp/sysreg-sr.h | 2 +- arch/arm64/kvm/hyp/nvhe/switch.c | 2 +- arch/arm64/kvm/hyp/vhe/switch.c | 2 +- arch/arm64/kvm/hypercalls.c | 2 +- arch/arm64/kvm/sys_regs.c | 2 +- arch/arm64/lib/memcpy.S | 3 +-- arch/arm64/lib/memmove.S | 3 +-- arch/arm64/lib/memset.S | 3 +-- arch/arm64/mm/fault.c | 2 +- include/linux/arm-smccc.h | 2 ++ include/linux/module.h | 2 +- .../selftests/arm64/mte/check_buffer_fill.c | 3 +++ .../selftests/arm64/mte/check_child_memory.c | 3 +++ .../selftests/arm64/mte/check_ksm_options.c | 4 ++++ .../selftests/arm64/mte/check_mmap_options.c | 4 ++++ .../selftests/arm64/mte/check_tags_inclusion.c | 3 +++ tools/testing/selftests/arm64/mte/check_user_mem.c | 4 ++++ 34 files changed, 119 insertions(+), 42 deletions(-)
