Enable event specification like:

Assuming that

This causes `perf list pmu` to show parameters for parameterized events

Event parameters are a basic way for partial events to be specified in
sysfs with per-event names given to the fields that need to be filled in
when using a particular event.
It is intended for supporting cases where the single 'cpu' parameter is
insufficient. For example, P

Hi Linus,
Please pull two powerpc fixes for 3.19:
The following changes since commit ec6f34e5b552fb0a52e6aae1a5afbbb1605cc6cc:
Linux 3.19-rc5 (2015-01-18 18:02:20 +1200)
are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux.git
tags/powerpc-3.19-5
This patch adds helper routine for lock and unlock hpte and use
the same for rest of the code. We don't change any locking rules in this
patch. In the next patch we switch some of the unlock usage to use
the api with barrier and also document the usage without barriers.

We switch to unlock variant with memory barriers in the error path
and also in code path where we had implicit dependency on previous
functions calling lwsync/ptesync. In most of the cases we don't really
need an explicit barrier, but using the variant make sure we don't make
mistakes later with co
