[GIT PULL] Perf, PMU and hw_breakpoint updates for 3.2

[will.deacon@arm.com (Will Deacon)]

Hi Russell,

Please pull these perf/pmu/hw_breakpoint updates for 3.2. Note that the
patch entitled "perf: provide PMU when initing events" is a cherry-pick
from tip/master.

I would have waited until -rc5 to send this, but I'm on holiday without
internet for the next couple of weeks. Instead this is taken against
the recent merge commit of your fixes branch by Linus.

Thanks,

Will
