Subject[PATCH tip/core/rcu 0/3] Documentation and rcutorture changes for 3.9
Hello!

The following are changes to documentation and rcutorture:

1. Export trace_clock_local() in order to allow rcutorture event
tracing to emit the time of the beginning of the RCU read-side
critical section at the point where a failure is detected.
2. Reduce rcutorture's read-side tracing to include only failures,
thus cutting the number of events down to something reasonable
(normally zero, in fact!).
3. Add atomic_xchg() to the list of atomic operations and memory
barriers, courtesy of Richard Braun.

Thanx, Paul
