Merge branch 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU fixes from Thomas Gleixner:
"Two RCU patches:
- Address a serious performance regression on open/close caused by
commit ac1bea85781e ("Make cond_resched() report RCU quiescent
states")
- Export RCU debug functions. Not a regression, but enablement to
address a serious recursion bug in the sl*b allocators in 3.17"
* 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
rcu: Reduce overhead of cond_resched() checks for RCU
rcu: Export debug_init_rcu_head() and and debug_init_rcu_head()
