Linus,

Please pull the latest core-rcu-for-linus git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git core-rcu-for-linus

# HEAD: 83086d654dd08c0f57381522e6819f421677706e Merge branch 'for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu

The changes in this cycle are:

- RCU flavor consolidation cleanups and optmizations
- Documentation updates
- Miscellaneous fixes
- SRCU updates
- RCU-sync flavor consolidation
- Torture-test updates
- Linux-kernel memory-consistency-model updates, most notably the addition of plain C-language accesses

Thanks,

Ingo
