linux/arch/arm64/kernel
Linus Torvalds 31a24ae89c arm64 updates for 5.13:
- MTE asynchronous support for KASan. Previously only synchronous
   (slower) mode was supported. Asynchronous is faster but does not allow
   precise identification of the illegal access.
 
 - Run kernel mode SIMD with softirqs disabled. This allows using NEON in
   softirq context for crypto performance improvements. The conditional
   yield support is modified to take softirqs into account and reduce the
   latency.
 
 - Preparatory patches for Apple M1: handle CPUs that only have the VHE
   mode available (host kernel running at EL2), add FIQ support.
 
 - arm64 perf updates: support for HiSilicon PA and SLLC PMU drivers, new
   functions for the HiSilicon HHA and L3C PMU, cleanups.
 
 - Re-introduce support for execute-only user permissions but only when
   the EPAN (Enhanced Privileged Access Never) architecture feature is
   available.
 
 - Disable fine-grained traps at boot and improve the documented boot
   requirements.
 
 - Support CONFIG_KASAN_VMALLOC on arm64 (only with KASAN_GENERIC).
 
 - Add hierarchical eXecute Never permissions for all page tables.
 
 - Add arm64 prctl(PR_PAC_{SET,GET}_ENABLED_KEYS) allowing user programs
   to control which PAC keys are enabled in a particular task.
 
 - arm64 kselftests for BTI and some improvements to the MTE tests.
 
 - Minor improvements to the compat vdso and sigpage.
 
 - Miscellaneous cleanups.
