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

[Nick Hu <nickhu@andestech.com>]

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

There are two patches in this letter:
1. Porting the memmove string operation.
2. Porting the feature KASAN.

Nick Hu (2):
  riscv: Add memmove string operation.
  riscv: Add KASAN support
