Subject: [PATCH V2 0/3] kprobe: Optimize the performance of patching ss

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.

v2:
Backport riscv patch to cksy and arm64.

Liao Chang (3):
  riscv/kprobe: Optimize the performance of patching single-step slot
  csky/kprobe: Optimize the performance of patching single-step slot
  arm64/kprobe: Optimize the performance of patching single-step slot
