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.

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"
