Pull ftrace test code from Steven Rostedt:
 "This patch series starts a new selftests section in the
  tools/testing/selftest directory called "ftrace" that holds tests
  aimed at testing ftrace and subsystems that use ftrace (like kprobes).

  So far only a few tests were written (by Masami Hiramatsu), but more
  will be added in the near future (3.19)"
