Linus Torvalds 46f8763228 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.

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.

  Summary:

   - 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.
