Merge branch 'for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu

Pull RCU updates from Paul E. McKenney:

 * Documentation updates, including fixes to the design-level
   requirements documentation and a fixed version of the design-level
   data-structure documentation.  These fixes include removing
   cartoons and getting rid of the html/htmlx duplication.

 * Further improvements to the new-age expedited grace periods.

 * Miscellaneous fixes.

 * Torture-test changes, including a new rcuperf module for measuring
   RCU grace-period performance and scalability, which is useful for
   the expedited-grace-period changes.
