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.

- 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"

selftests: arm64: More comprehensively test the SVE ptrace interface

Currently the selftest for the SVE register set is not quite as thorough
as is desirable - it only validates that the value of a single Z register
is not modified by a partial write to a lower numbered Z register after
having previously been set through the FPSIMD regset.

Make this more thorough:
- Test the ability to set vector lengths and enumerate those supported in
the system.
- Validate data in all Z and P registers, plus FPSR and FPCR.
- Test reads via the FPSIMD regset after set via the SVE regset.

There's still some oversights, the main one being that due to the need to
generate a pattern in FFR and the fact that this rewrite is primarily
motivated by SME's streaming SVE which doesn't have FFR we don't currently
test FFR. Update the TODO to reflect those that occurred to me (and fix an
adjacent typo in there).

Pull arm64 updates from Catalin Marinas:

- Support for 32-bit tasks on asymmetric AArch32 systems (on top of the
scheduler changes merged via the tip tree).

- More entry.S clean-ups and conversion to C.

- MTE updates: allow a preferred tag checking mode to be set per CPU
(the overhead of synchronous mode is smaller for some CPUs than
others); optimisations for kernel entry/exit path; optionally disable
MTE on the kernel command line.

- Kselftest improvements for SVE and signal handling, PtrAuth.

- Fix unlikely race where a TLBI could use stale ASID on an ASID
roll-over (found by inspection).

- Miscellaneous fixes: disable trapping of PMSNEVFR_EL1 to higher
exception levels; drop unnecessary sigdelsetmask() call in the
signal32 handling; remove BUG_ON when failing to allocate SVE state
(just signal the process); SYM_CODE annotations.

- Other trivial clean-ups: use macros instead of magic numbers, remove
redundant returns, typos.
