This patch set is to fix several issues of single-step debugging in kgdb/kdb on arm64.
It seems that these issues have been shelved a very long time, but i still hope to solve them, as the single-step debugging is an useful feature.
Note: Based on patch "arm64: cacheflush: Fix KGDB trap detection", https://www.spinics.net/lists/arm-kernel/msg803741.html
