Linus Torvalds 8bf1a529cd arm64 updates for 6.3:
- Support for arm64 SME 2 and 2.1. SME2 introduces a new 512-bit
   architectural register (ZT0, for the look-up table feature) that Linux
   needs to save/restore.
 
 - Include TPIDR2 in the signal context and add the corresponding
   kselftests.
 
 - Perf updates: Arm SPEv1.2 support, HiSilicon uncore PMU updates, ACPI
   support to the Marvell DDR and TAD PMU drivers, reset DTM_PMU_CONFIG
   (ARM CMN) at probe time.
 
 - Support for DYNAMIC_FTRACE_WITH_CALL_OPS on arm64.
 
 - Permit EFI boot with MMU and caches on. Instead of cleaning the entire
   loaded kernel image to the PoC and disabling the MMU and caches before
   branching to the kernel bare metal entry point, leave the MMU and
   caches enabled and rely on EFI's cacheable 1:1 mapping of all of
   system RAM to populate the initial page tables.
 
 - Expose the AArch32 (compat) ELF_HWCAP features to user in an arm64
   kernel (the arm32 kernel only defines the values).
 
 - Harden the arm64 shadow call stack pointer handling: stash the shadow
   stack pointer in the task struct on interrupt, load it directly from
   this structure.
 
 - Signal handling cleanups to remove redundant validation of size
   information and avoid reading the same data from userspace twice.
 
 - Refactor the hwcap macros to make use of the automatically generated
   ID registers. It should make new hwcaps writing less error prone.
 
 - Further arm64 sysreg conversion and some fixes.
 
 - arm64 kselftest fixes and improvements.
 
 - Pointer authentication cleanups: don't sign leaf functions, unify
   asm-arch manipulation.
 
 - Pseudo-NMI code generation optimisations.
 
 - Minor fixes for SME and TPIDR2 handling.
 
 - Miscellaneous updates: ARCH_FORCE_MAX_ORDER is now selectable, replace
   strtobool() to kstrtobool() in the cpufeature.c code, apply dynamic
   shadow call stack in two passes, intercept pfn changes in set_pte_at()
   without the required break-before-make sequence, attempt to dump all
   instructions on unhandled kernel faults.
