[PATCH 00/20] perf report: Add support for event group view (v3)

[Namhyung Kim]

Hi,

This is my v3 of event group view support.
For basic idea and usage example, please see my original post [1].

I rebased the series on top of selected hpp changes from Jiri's diff
patchset [2] since it contains cleanups and improves that can be used
in this series too.

You can also get it via my tree at:

git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git  perf/group-v3

Any comments are welcome, thanks,
Namhyung

v2 -> v3:
 * drop patch 1 since it's merged into acme/perf/core
 * cherry-pick Jiri's hpp changes
 * add missing bswap_32 on reading nr_groups (Jiri)
 * remove perf_evlist__recalc_nr_groups() in favor of list_is_last (Jiri)

v1 -> v2:
 * save group relation to header (Jiri)
