[PATCH v2 0/2] arm64: unwind_frame for interrupt stack

[AKASHI Takahiro]

Jungseok is going to introduce a dedicated interrupt stack[1] for arm64.
This patch is my second proposal to support interrupt stack in
unwind_frame() and address an issue I mentioned in [2].

Patch[3] is also a prerequisite.
