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

Pull perf fixes from Ingo Molnar:
 "Tooling fixes, plus a simple hardware-enablement patch for the Intel
  RAPL PMU (energy use measurement) on Haswell CPUs, which I hope is
  still fine at this stage"

* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  perf tools: Instead of redirecting flex output, use -o
  perf tools: Fix double free in perf test 21 (code-reading.c)
  perf stat: Initialize statistics correctly
  perf bench: Set more defaults in the 'numa' suite
  perf bench: Fix segfault at the end of an 'all' execution
  perf bench: Update manpage to mention numa and futex
  perf probe: Use dwarf_getcfi_elf() instead of dwarf_getcfi()
  perf probe: Fix to handle errors in line_range searching
  perf probe: Fix --line option behavior
  perf tools: Pick up libdw without explicit LIBDW_DIR
  MAINTAINERS: Change e-mail to kernel.org one
  perf callchains: Disable unwind libraries when libelf isn't found
  tools lib traceevent: Do not call warning() directly
  tools lib traceevent: Print event name when show warning if possible
  perf top: Fix documentation of invalid -s option
  perf/x86: Enable DRAM RAPL support on Intel Haswell
