tracing: Export trace_clock_local()
The rcutorture tests need to be able to trace the time of the beginning of an RCU read-side critical section, and thus need access to trace_clock_local(). This commit therefore adds a the needed EXPORT_SYMBOL_GPL(). Signed-off-by: Paul E. McKenney <paul.mckenney@linaro.org> Reviewed-by: Josh Triplett <josh@joshtriplett.org>
