Subject: [PATCH 00/16] perf report: Add suppport for event group view (v2)

Hi,

This is my second attempt to support event group on perf report.
For basic idea and usage example, please see my original post [1].

The main difference than v1 is adding HEADER_GROUP_DESC feature and
use it for regenerating group relationship on perf report.  It will
save actual (i.e. contains non-leader member) group information to
perf header.

Patch 1 is a bug fix which can be applied indenpedently.

Patch 2-4 are cleanups to facilitate later changes and came from my
cumulative report series [2].

You can also access it via my tree at:

git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git  perf/group-v2

Any comments are welcome, thanks,
Namhyung

v1 -> v2:
 * save group relation to header (Jiri)
 * rebase on top of current acme/perf/core
