Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Thomas Gleixner: "Three fixlets for perf: - add a missing NULL pointer check in the intel BTS driver - make BTS an exclusive PMU because BTS can only handle one event at a time - ensure that exclusive events are limited to one PMU so that several exclusive events can be scheduled on different PMU instances" * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf/core: Limit matching exclusive events to one PMU perf/x86/intel/bts: Make it an exclusive PMU perf/x86/intel/bts: Make sure debug store is valid
