ACPI:
- Add interrupt signalling support to the AGDI handler.
- Add Catalin and myself to the arm64 ACPI MAINTAINERS entry.
CPU features:
- Drop Kconfig options for PAN and LSE (these are detected at runtime).
- Add support for 64-byte single-copy atomic instructions (LS64/LS64V).
- Reduce MTE overhead when executing in the kernel on Ampere CPUs.
- Ensure POR_EL0 value exposed via ptrace is up-to-date.
- Fix error handling on GCS allocation failure.
CPU frequency:
- Add CPU hotplug support to the FIE setup in the AMU driver.
Entry code:
- Minor optimisations and cleanups to the syscall entry path.
- Preparatory rework for moving to the generic syscall entry code.
Hardware errata:
- Work around Spectre-BHB on TSV110 processors.
- Work around broken CMO propagation on some systems with the SI-L1
interconnect.
Miscellaneous:
- Disable branch profiling for arch/arm64/ to avoid issues with noinstr.
- Minor fixes and cleanups (kexec + ubsan, WARN_ONCE() instead of
WARN_ON(), reduction of boolean expression).
- Fix custom __READ_ONCE() implementation for LTO builds when operating
on non-atomic types.
Perf and PMUs:
- Support for CMN-600AE.
- Be stricter about supported hardware in the CMN driver.
- Support for DSU-110 and DSU-120.
- Support for the cycles event in the DSU driver (alongside the
dedicated cycles counter).
- Use IRQF_NO_THREAD instead of IRQF_ONESHOT in the cxlpmu driver.
- Use !bitmap_empty() as a faster alternative to bitmap_weight().
- Fix SPE error handling when failing to resume profiling.
Selftests:
- Add support for the FORCE_TARGETS option to the arm64 kselftests.
- Avoid nolibc-specific my_syscall() function.
- Add basic test for the LS64 HWCAP.
- Extend fp-pidbench to cover additional workload patterns.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"There's a little less than normal, probably due to LPC & Christmas/New
Year meaning that a few series weren't quite ready or reviewed in
time. It's still useful across the board, despite the only real
feature being support for the LS64 feature enabling 64-byte atomic
accesses to endpoints that support it.
