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()
