Subject: [PATCH v3 0/3] 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

Changes in v3:
  - Update the KASAN documentation to mention that riscv is supported.

Nick Hu (3):
  kasan: Archs don't check memmove if not support it.
  riscv: Add KASAN support
  kasan: Add riscv to KASAN documentation.
