- 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.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"There's the usual summary below, 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.
