[PATCH V3 0/3] kprobe: Optimize the performance of patching ss

[Liao Chang]

Single-step slot would not be used until kprobe is enabled, that means
no race condition occurs on it under SMP, hence it is safe to pacth ss
slot without stopping machine.

v3:
1. Drop duplicated I-Cache maintenance for arm64.
2. Add Acked-by from Masami Hiramatsu.

v2:
Backport riscv patch to cksy and arm64.

  csky/kprobe: Optimize the performance of patching single-step slot
  arm64/kprobe: Optimize the performance of patching single-step slot
