Merge branch 'rcu/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu
Pull RCU fixes from Paul McKenney:
"A couple of fixes for RCU regressions:
- A boneheaded boolean-logic bug that resulted in excessive delays on
boot, hibernation and suspend that was reported by Borislav Petkov,
Bjørn Mork, and Joerg Roedel. The fix inserts a single "!".
- A fix for a boot-time splat due to allocating from bootmem too late
in boot, fix courtesy of Sasha Levin with additional help from
Yinghai Lu."
* 'rcu/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu:
rcu: Don't allocate bootmem from rcu_init()
rcu: Fix comparison sense in rcu_needs_cpu()
