Subject: [PATCH v2 0/2] KASAN support for RISC-V

KASAN is an important runtime memory debugging feature in linux kernel
which can detect use-after-free and out-of- bounds problems.

Changes in v2:
  - Remove the porting of memmove and exclude the check instead.
  - Fix some code noted by Christoph Hellwig

Nick Hu (2):
  kasan: Archs don't check memmove if not support it.
  riscv: Add KASAN support
