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

Pull perf fixes from Ingo Molnar:
 "The tree contains three fixes:

   - Two tooling fixes

   - Reversal of the new 'MMAP2' extended mmap record ABI, introduced in
     this merge window.  (Patches were proposed to fix it but it was all
     a bit late and we felt it's safer to just delay the ABI one more
     kernel release and do it right)"

* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  perf: Disable PERF_RECORD_MMAP2 support
  perf scripting perl: Fix build error on Fedora 12
  perf probe: Fix to initialize fname always before use it
