Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Ingo Molnar:
"Fix merge window fallout and fix sleep profiling (this was always
broken, so it's not a fix for the merge window - we can skip this one
from the head of the tree)."
* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
perf/trace: Add ability to set a target task for events
perf/x86: Fix USER/KERNEL tagging of samples properly
perf/x86/intel/uncore: Make UNCORE_PMU_HRTIMER_INTERVAL 64-bit
