[PATCHSET 00/23] perf tools: Add -q/--quiet option

[Namhyung Kim]

Hello,

This patchset adds -q/--quiet option for most commands.  I skipped
commands missing -v/--verbose option.  While the -q option in this
patchset just suppresses warning messages, some command might want to
mute other outputs too.  I added a few obvious ones and if you have
some thought, please let me know.

The patch 1, 4 and 5 are fixes and can be applied separately.

The code is available on the 'perf/quiet-v2' branche on my tree

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

Thanks,
Namhyung
