Workaround: do not set rq->skip_clock_update
Disabling the clock update seems to be causing problems even in normal Linux, and causes major bugs under LITMUS^RT. As a workaround, just disable this "optimization" for now. Details: the idle load balancer causes tasks that suspsend to be marked with set_tsk_need_resched(). When such a task resumes, it may wrongly trigger the setting of skip_clock_update. However, a corresponding rescheduling event may not happen immediately, such that the currently-scheduled task is no longer charged for its execution time.
