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

Pull perf updates from Ingo Molnar:
 "This update is pretty big and almost exclusively includes tooling
  changes, because v4.9's LTS status forced to completion most of the
  pending kernel side hardware enablement work and because we tried to
  freeze core perf work a bit to give a time window for the fuzzing
  efforts.

  The diff is large mostly due to the JSON hardware event tables added
  for Intel and Power8 CPUs. This was a popular feature request from
  people working close to hardware and from the HPC community.

  Tree size is big because this added the CPU event tables for over a
  decade of Intel CPUs. Future changes for a CPU vendor alrady support
  should be much smaller, as events for new models are added. The new
  events are listed in 'perf list', for the CPU model the tool is
  running on. If you find an interesting event it can be used as-is:

      $ perf stat -a -e l2_lines_out.pf_clean sleep ...
