Merge tag 'csky-for-linus-5.3-rc1' of git://github.com/c-sky/csky-linux
Pull arch/csky pupdates from Guo Ren:
"This round of csky subsystem gives two features (ASID algorithm
update, Perf pmu record support) and some fixups.
ASID updates:
- Revert mmu ASID mechanism
- Add new asid lib code from arm
- Use generic asid algorithm to implement switch_mm
- Improve tlb operation with help of asid
Perf pmu record support:
- Init pmu as a device
- Add count-width property for csky pmu
- Add pmu interrupt support
- Fix perf record in kernel/user space
- dt-bindings: Add csky PMU bindings
Fixes:
- Fixup no panic in kernel for some traps
- Fixup some error count in 810 & 860.
- Fixup abiv1 memset error"
