Merge branch 'rcu/urgent' of git://git.kernel.org/pub/scm/linux/kerne…

…l/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()
