Subject: [PATCH 0/9] perf tools: Enhance and correct srcline behavior

Hello,

This patchset tries to fix and enhance current srcline behavior.

Firstly it doesn't actually sort by srcline info but by ip.  I suspect
it was because of a performance reason to run external addr2line
utility.  It showed the srcline info after hist entries were
collapsed.  Thanks to Roberto, we now have internal implementation of
addr2line using libbfd so can sort/compare by srcline of entries.

Second problem for me was it sometimes printed "??:0" and sometimes
printed a raw ip value for unknown srcline info.  I changed to print
the former consistently.

While at it, I found some bugs/leaks in srcline handling.  Patch 1-3
are fixes for those and can be merged separately.

You can get this series on my 'perf/srcline-v1' branch in my tree at:

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Any comments are welcome, thanks.
Namhyung
