Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull RCU updates from Ingo Molnar:
 "The main RCU changes in this cycle are:

   - Idle entry/exit changes, to throttle callback execution and other
     refinements to speed up kbuild, primarily to address performance
     issues located by Tibor Billes.

   - Grace-period related changes, primarily to aid in debugging,
     inspired by an -rt debugging session.

   - Code reorganization moving RCU's source files into its own
     kernel/rcu/ directory.

   - RCU documentation updates

   - Miscellaneous fixes.

  Note, the following commit:

    5c889690aa08 mm: Place preemption point in do_mlockall() loop

  is identical to the commit already in your tree via email:

    22356f447ceb mm: Place preemption point in do_mlockall() loop

  [ Your version of the changelog nicely demonstrates it how kernel oops
    messages should be trimmed properly :-/ ]"
