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 main RCU changes in this development cycle were:
- Miscellaneous fixes, including a change to call_rcu()'s rcu_head
alignment check.
- Security-motivated list consistency checks, which are disabled by
default behind DEBUG_LIST.
- Torture-test updates.
- Documentation updates, yet again just simple changes"
