-	check_thread_timers(tsk, &firing);
+	if (!task_cputime_zero(&tsk->cputime_expires))
+		check_thread_timers(tsk, &firing);

Sincere question; I'm not certain myself: would it make more sense to put
this shortcut into check_thread_timers()?

It seems more like an optimization of that function than something the
caller needs to know about.
