Pull ftrace fix from Steven Rostedt:
 "This fixes a long standing bug in the ftrace profiler.  The problem is
  that the profiler only initializes the online CPUs, and not possible
  CPUs.  This causes issues if the user takes CPUs online or offline
  while the profiler is running.

  If we online a CPU after starting the profiler, we lose all the trace
  information on the CPU going online.

  If we offline a CPU after running a test and start a new test, it will
  not clear the old data from that CPU.

  This bug causes incorrect data to be reported to the user if they
  online or offline CPUs during the profiling"
