6734e20e39207556e17d72b5c4950d8f3a4f2de2 - Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Mon, 12 Oct 2020 19:00:51 +0200

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linuxPull arm64 updates from Will Deacon: "There's quite a lot of code here, but much of it is due to the addition of a new PMU driver as well as some arm64-specific selftests which is an area where we've traditionally been lagging a bit. In terms of exciting features, this includes support for the Memory Tagging Extension which narrowly missed 5.9, hopefully allowing userspace to run with use-after-free detection in production on CPUs that support it. Work is ongoing to integrate the feature with KASAN for 5.11. Another change that I'm excited about (assuming they get the hardware right) is preparing the ASID allocator for sharing the CPU page-table with the SMMU. Those changes will also come in via Joerg with the IOMMU pull. We do stray outside of our usual directories in a few places, mostly due to core changes required by MTE. Although much of this has been Acked, there were a couple of places where we unfortunately didn't get any review feedback. Other than that, we ran into a handful of minor conflicts in -next, but nothing that should post any issues. Summary: - Userspace support for the Memory Tagging Extension introduced by Armv8.5. Kernel support (via KASAN) is likely to follow in 5.11. - Selftests for MTE, Pointer Authentication and FPSIMD/SVE context switching. - Fix and subsequent rewrite of our Spectre mitigations, including the addition of support for PR_SPEC_DISABLE_NOEXEC. - Support for the Armv8.3 Pointer Authentication enhancements. - Support for ASID pinning, which is required when sharing page-tables with the SMMU. - MM updates, including treating flush_tlb_fix_spurious_fault() as a no-op. - Perf/PMU driver updates, including addition of the ARM CMN PMU driver and also support to handle CPU PMU IRQs as NMIs. - Allow prefetchable PCI BARs to be exposed to userspace using normal non-cacheable mappings. - Implementation of ARCH_STACKWALK for unwinding. - Improve reporting of unexpected kernel traps due to BPF JIT failure. - Improve robustness of user-visible HWCAP strings and their corresponding numerical constants. - Removal of TEXT_OFFSET. - Removal of some unused functions, parameters and prototypes. - Removal of MPIDR-based topology detection in favour of firmware description. - Cleanups to handling of SVE and FPSIMD register state in preparation for potential future optimisation of handling across syscalls. - Cleanups to the SDEI driver in preparation for support in KVM. - Miscellaneous cleanups and refactoring work"* tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (148 commits) Revert "arm64: initialize per-cpu offsets earlier" arm64: random: Remove no longer needed prototypes arm64: initialize per-cpu offsets earlier kselftest/arm64: Check mte tagged user address in kernel kselftest/arm64: Verify KSM page merge for MTE pages kselftest/arm64: Verify all different mmap MTE options kselftest/arm64: Check forked child mte memory accessibility kselftest/arm64: Verify mte tag inclusion via prctl kselftest/arm64: Add utilities and a test to validate mte memory perf: arm-cmn: Fix conversion specifiers for node type perf: arm-cmn: Fix unsigned comparison to less than zero arm64: dbm: Invalidate local TLB when setting TCR_EL1.HD arm64: mm: Make flush_tlb_fix_spurious_fault() a no-op arm64: Add support for PR_SPEC_DISABLE_NOEXEC prctl() option arm64: Pull in task_stack_page() to Spectre-v4 mitigation code KVM: arm64: Allow patching EL2 vectors even with KASLR is not enabled arm64: Get rid of arm64_ssbd_state KVM: arm64: Convert ARCH_WORKAROUND_2 to arm64_get_spectre_v4_state() KVM: arm64: Get rid of kvm_arm_have_ssbd() KVM: arm64: Simplify handling of ARCH_WORKAROUND_2 ...
