Linus Torvalds c620f7bd0b arm64 updates for 5.2 
Mostly just incremental improvements here:
 
 - Introduce AT_HWCAP2 for advertising CPU features to userspace
 
 - Expose SVE2 availability to userspace
 
 - Support for "data cache clean to point of deep persistence" (DC PODP)
 
 - Honour "mitigations=off" on the cmdline and advertise status via sysfs
 
 - CPU timer erratum workaround (Neoverse-N1 #1188873)
 
 - Introduce perf PMU driver for the SMMUv3 performance counters
 
 - Add config option to disable the kuser helpers page for AArch32 tasks
 
 - Futex modifications to ensure liveness under contention
 
 - Rework debug exception handling to seperate kernel and user handlers
 
 - Non-critical fixes and cleanup
