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, yet again just simple changes.
- 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.
