Subject[PATCH 0/4] arm64: kgdb/kdb: Fix single-step debugging issues
Date
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

Wei Li (4):
arm64: kgdb: Fix single-step exception handling oops
arm64: Extract kprobes_save_local_irqflag() and
kprobes_restore_local_irqflag()
arm64: kgdb: Fix single-stepping into the irq handler wrongly
arm64: kgdb: Set PSTATE.SS to 1 to reenable single-step
