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

89c683cd · Linus Torvalds <[email protected]> · 2019-12-17 11:03:57 -08:00

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"
