Subject: [PATCH 05/21] perf tools: Update cpumode for each cumulative entry
Date: Thu, 23 Jan 2014 09:13:49 +0900	[thread overview]
Message-ID: <1390436045-16830-6-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1390436045-16830-1-git-send-email-namhyung@kernel.org>

The cpumode and level in struct addr_localtion was set for a sample
and but updated as cumulative callchains were added.  This led to have
non-matching symbol and cpumode in the output.

Update it accordingly based on the fact whether the map is a part of
the kernel or not.  This is a reverse of what thread__find_addr_map()
does.
