Pull tracing fix from Steven Rostedt:
 "I previously sent a fix that prevents all trace events from being
  called if the current cpu is offline.

  But I forgot that in 3.18, we added lockdep checks to test RCU usage
  even when the event is disabled.  Although there cannot be any bug
  when a cpu is going offline, we now get false warnings triggered by
  the added checks of the event being disabled.

  I removed the check from the tracepoint code itself, and added it to
  the condition section (which is "1" for 'no condition').  This way the
  online cpu check will get checked in all the right locations"
