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:
 "This contains five tooling fixes:

   - fix a remaining mmap2 assumption which resulted in perf top output
     breakage
   - fix mmap ring-buffer processing bug that corrupts data
   - fix for a severe python scripting memory leak
   - fix broken (and user-visible) -g option handling
   - fix stdio output

  The diffstat size is larger than what we'd like to see this late :-/"
