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 RCU changes in this cycle are:
- Dynticks updates, consolidating open-coded counter accesses into a
well-defined API
- SRCU updates: Simplify algorithm, add formal verification
- Documentation updates
- Miscellaneous fixes
- Torture-test updates
Most of the diffstat comes from the relatively large documentation
update"
