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
