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)"
