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 major changes:
- Simplify RCU's grace-period and callback processing based on the new
numbering for callbacks.
- Removal of TINY_PREEMPT_RCU in favor of TREE_PREEMPT_RCU for
single-CPU low-latency systems.
- SRCU-related changes and fixes.
- Miscellaneous fixes, including converting a few remaining printk()
calls to pr_*().
- Documentation updates"
