Subject: [PATCH 01/21] perf machine: Set kernel data mapping length
Date: Fri,  9 Nov 2012 18:42:50 -0300	[thread overview]
Message-ID: <1352497390-17716-2-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1352497390-17716-1-git-send-email-acme@infradead.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.
