[GIT PULL] arm64 updates for 5.10
From: Will Deacon
Date: Fri Oct 09 2020 - 10:16:25 EST
Hi Linus,
Please pull the following arm64 updates for 5.10. 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.
Full summary in the tag.
Cheers,
Will
P.S. I've renewed my pgp subkeys, so you may need to refetch from
pgpkeys.git in order to validate the tag. It was the usual painful
experience when my signatures suddenly started failing and I couldn't
figure out why...

Revert "arm64: initialize per-cpu offsets earlier" (2020-10-09 11:24:17 +0100)
----------------------------------------------------------------
arm64 updates for 5.10
- 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.
