Merge tag 'perf-core-for-mingo' of...

Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Fixes for the last batch from Namhyung and the initial GTK report browser
from Pekka.
Signed-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>
Where: /sys/bus/event_source/devices/<dev>/format
Date: January 2012
Kernel Version: 3.3
Contact: Jiri Olsa <jolsa@redhat.com>
Description:
Attribute group to describe the magic bits that go into
perf_event_attr::config[012] for a particular pmu.
Each attribute of this group defines the 'hardware' bitmask
we want to export, so that userspace can deal with sane
name/value pairs.
Example: 'config1:1,6-10,44'
Defines contents of attribute that occupies bits 1,6-10,44 of
perf_event_attr::config1.
