The patch making need_resched() respond to urgent RCU-QS needs used is_idle_task(current) to detect an interrupt from idle, which does work reasonably, but is (in theory at least) vulnerable to loops containing need_resched() invoked from within RCU_NONIDLE() or its tracepoint equivalent. This commit therefore moves rcu_is_cpu_rrupt_from_idle() to a place from which rcu_check_callbacks() can invoke it and replaces the is_idle_task(current) with rcu_is_cpu_rrupt_from_idle().
