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. Since I and D caches are coherent within single-step slot from aarch64_insn_patch_text_nosync(), hence no need to do it again via flush_icache_range().
