Pull tracing fix from Steven Rostedt:
 "Fix output of top level event tracing 'enable' file.

  When writing a tool for enabling events in the tracing system, an
  anomaly was discovered. The top level event 'enable' file would never
  show '1' when all events were enabled.

  The system and event 'enable' files worked as expected.

  The reason was because the top level event 'enable' file included the
  'ftrace' tracer events, which are not controlled by the 'enable' file
  and would cause the output to be wrong. This appears to have been a
  bug since it was created"
