Paul E. McKenney 36741bfcfb rcu-tasks: Idle tasks on offline CPUs are in quiescent states ...

commit 5c9a9ca44f upstream.

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.
