Subject: [GIT PULL] arm64 updates for 5.14
Hi Linus,
Please pull this pile of arm64 updates for 5.14. There's a reasonable
amount here and the juicy details are all in the tag. We've run into a
handful of trivial conflicts in -next, but please shout if any of the
resolutions are unclear.
It's worth noting that the MTE/KASAN changes strayed outside of our
usual directories due to core mm changes and some associated changes to
some other architectures; Andrew asked for us to carry these [1] rather
that take them via the -mm tree.
We've also pulled in a branch from -tip which allows our perf drivers to
handle IRQ affinity setting properly.
Cheers,
Will

Merge branch 'for-next/sve' into for-next/core (2021-06-24 14:07:04 +0100)
----------------------------------------------------------------
arm64 updates for 5.14
- Optimise SVE switching for CPUs with 128-bit implementations.
- Fix output format from SVE selftest.
- Add support for versions v1.2 and 1.3 of the SMC calling convention.
- Allow Pointer Authentication to be configured independently for
kernel and userspace.
- PMU driver cleanups for managing IRQ affinity and exposing event
attributes via sysfs.
- KASAN optimisations for both hardware tagging (MTE) and out-of-line
software tagging implementations.
- Relax frame record alignment requirements to facilitate 8-byte
alignment with KASAN and Clang.
- Cleanup of page-table definitions and removal of unused memory types.
- Reduction of ARCH_DMA_MINALIGN back to 64 bytes.
- Refactoring of our instruction decoding routines and addition of some
missing encodings.
- Move entry code moved into C and hardened against harmful compiler
instrumentation.
- Update booting requirements for the FEAT_HCX feature, added to v8.7
of the architecture.
- Fix resume from idle when pNMI is being used.
- Additional CPU sanity checks for MTE and preparatory changes for
systems where not all of the CPUs support 32-bit EL0.
- Update our kernel string routines to the latest Cortex Strings
implementation.
- Big cleanup of our cache maintenance routines, which were confusingly
named and inconsistent in their implementations.
- Tweak linker flags so that GDB can understand vmlinux when using RELR
relocations.
- Boot path cleanups to enable early initialisation of per-cpu
operations needed by KCSAN.
- Non-critical fixes and miscellaneous cleanup.
