Paul E. McKenney 8eb74b2b29 rcu: Rework preemptible expedited bitmask handling
Currently, the rcu_node tree ->expmask bitmasks are initially set to
reflect the online CPUs.  This is pointless, because only the CPUs
preempted within RCU read-side critical sections by the preceding
synchronize_sched_expedited() need to be tracked.  This commit therefore
instead sets up these bitmasks based on the state of the ->blkd_tasks
lists.
