Linus Torvalds 45bf4bc87c arm64 updates for 7.0
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.

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.
