linux/arch/arm64/mm
Linus Torvalds 57c78a234e arm64 updates for 5.15:
- 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.
