Hi Linus,
Please pull this batch of arm64 updates for 5.16. There's the usual
summary in the tag, but the highlights are support for the Armv8.6
timer extensions, KASAN support for asymmetric MTE, the ability to
kexec() with the MMU enabled and a second attempt at switching to the
generic pfn_valid() implementation.
Please note that the changes to the "arm_arch_timer" driver on which we
depend are shared with Daniel and should also come via the -tip tree.
Cheers,
Will

Merge branch 'for-next/fixes' into for-next/core (2021-10-29 12:27:53 +0100)
----------------------------------------------------------------
arm64 updates for 5.16
- Support for the Arm8.6 timer extensions, including a self-synchronising
view of the system registers to elide some expensive ISB instructions.
- Exception table cleanup and rework so that the fixup handlers appear
correctly in backtraces.
- A handful of miscellaneous changes, the main one being selection of
CONFIG_HAVE_POSIX_CPU_TIMERS_TASK_WORK.
- More mm and pgtable cleanups.
- KASAN support for "asymmetric" MTE, where tag faults are reported
synchronously for loads (via an exception) and asynchronously for
stores (via a register).
- Support for leaving the MMU enabled during kexec relocation, which
significantly speeds up the operation.
- Minor improvements to our perf PMU drivers.
- Improvements to the compat vDSO build system, particularly when
building with LLVM=1.
- Preparatory work for handling some Coresight TRBE tracing errata.
- Cleanup and refactoring of the SVE code to pave the way for SME
support in future.
- Ensure SCS pages are unpoisoned immediately prior to freeing them
when KASAN is enabled for the vmalloc area.
- Try moving to the generic pfn_valid() implementation again now that
the DMA mapping issue from last time has been resolved.
- Numerous improvements and additions to our FPSIMD and SVE selftests.
