Subject: [PATCHSET 00/11] perf stat: Cleanup perf stat output display (v2)

Hello,

I'm working on cleaning up the perf stat code and found a number of issues.
Before moving on to the real changes, I'd like to fix those first.  I'll
think about how to test this properly.

changes in v2)
 * move applied patches to the beginning  (Arnaldo)
 * make it error to use --interval-clear with other output  (Ian)
 * add two more patches for CSV output
 * add Acked-by from Ian

You can get it from 'perf/stat-cleanup-v2' branch in

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

Thanks,
Namhyung
