[PATCH 0/7] perf header: Save and reuse feature information in header (v2)

[Namhyung Kim <namhyung@kernel.org>]

Hi,

This is a v2 of my perf header cleanup series.  The v1 can be found
here [1].

Currently the perf header information is used only at initial setup
time and discarded.  If it's saved we could reuse the information for
various purpose in the future.

The patch 1-3 are cleanups so that they can be applied independently.

I also put the series on my tree at:

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

Any comments are welcome, thanks.
