Paul E. McKenney 4d1114c054 rcu-tasks: Abstract checking of callback lists 
This commit adds a rcu_tasks_need_gpcb() function that returns an
indication of whether another grace period is required, and if no grace
period is required, whether there are callbacks that need to be invoked.
The function scans all per-CPU lists currently in use.
