Subject: [PATCH v2 0/2] arm64: unwind_frame for interrupt stack
Date: Tue, 20 Oct 2015 17:00:17 +0900 [thread overview]
Message-ID: <1445328019-23330-1-git-send-email-takahiro.akashi@linaro.org> (raw)
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.
