Subject: [PATCH 2/6] perf tools: Set kernel data mapping length
Date: Wed,  7 Nov 2012 16:27:10 +0900	[thread overview]
Message-ID: <1352273234-28912-3-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1352273234-28912-1-git-send-email-namhyung@kernel.org>

From: Namhyung Kim <namhyung.kim@lge.com>

Currently only text (function) mapping was set, so that the kernel
data addresses couldn't parsed correctly.  Fix it.
