This patch-set reworks pending fixes from Wei's series [1] to make single-step debugging via kgdb/kdb on arm64 work as expected. There was a prior discussion on ML [2] regarding if we should keep the interrupts enabled during single-stepping. So patch #1 follows suggestion from Will [3] to not disable interrupts during single stepping but rather skip single stepping within interrupt handler.

Changes in v4: - Rebased to the tip of mainline. - Picked up Doug's Tested-by tag.
Changes in v3: - Reword commit descriptions as per Daniel's suggestions.
Changes in v2: - Replace patch #1 to rather follow Will's suggestion.
