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.
