[PATCH v2 0/3] arm64: kgdb: fix single stepping

[AKASHI Takahiro]

Kgdb support on arm64 was merged in v3.15, but from its first appearance,
"signle step" has never worked well.

This patch fixes all the error cases I found so far.
The original patch[1] was splitted into three pieces, ones for each case.
patch#1, #2 should be applied to all the version, v3.15 and later.
pathc#3 only for v3.16 and later.
