Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf fixes from Ingo Molnar:
 "Mostly tooling fixes, plus on the kernel side:

   - a revert for a newly introduced PMU driver which isn't complete yet
     and where we ran out of time with fixes (to be tried again in
     v3.19) - this makes up for a large chunk of the diffstat.

   - compilation warning fixes

   - a printk message fix

   - event_idx usage fixes/cleanups"
