Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf tooling fixes from Ingo Molnar:
"These are all perf tooling changes: most of them are fixes.
Note that the large CPU count related fixes go beyond regression
fixes, but the IPI-flood symptoms are severe enough that I think
justifies their inclusion"
