Subject: perf symbols: Create thread__find_addr_map from thread__find_addr_location
X-Git-Tag: v2.6.34-rc1~197^2~124
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=59ee68ecd1561a233fb6ad351980bea8402533e7;p=karo-tx-linux.git

perf symbols: Create thread__find_addr_map from thread__find_addr_location

Because some tools will only want to know with maps had hits,
not needing the full symbol resolution done by
thread__find_addr_location.
