Paul E. McKenney 2655d57ef3 rcu: prevent call_rcu() from diving into rcu core if irqs disabled 
This commit marks a first step towards making call_rcu() have
real-time behavior.  If irqs are disabled, don't dive into the
RCU core.  Later on, this new early exit will wake up the
per-CPU kthread, which first must be modified to handle the
cases involving callback storms.
