Merge branch 'core/rcu' into perf/core

Steve Rostedt asked for the merge of a single commit, into both
the RCU and the perf/tracing tree:

 | Josh made a change to the tracing code that affects both the
 | work Paul McKenney and I are currently doing. At the last
 | Kernel Summit back in August, Linus said when such a case
 | exists, it is best to make a separate branch based off of his
 | tree and place the change there. This way, the repositories
 | that need to share the change can both pull them in and the
 | SHA1 will match for both. Whichever branch is pulled in first
 | by Linus will also pull in the necessary change for the other
 | branch as well.
