Paul E. McKenney 5c9a9ca44f rcu-tasks: Idle tasks on offline CPUs are in quiescent states 
Any idle task corresponding to an offline CPU is in an RCU Tasks Trace
quiescent state.  This commit causes rcu_tasks_trace_postscan() to ignore
idle tasks for offline CPUs, which it can do safely due to CPU-hotplug
operations being disabled.
