  Modified files:
    sys/kern             sched_ule.c 
  Log:
   - sched_prio() should only adjust tdq_lowpri if the thread is running or on
     a run-queue.  If the priority is numerically raised only change lowpri
     if we're certain it will be correct.  Some slop is allowed however
     previously we could erroneously raise lowpri for an idle cpu that a
     thread had recently run on which lead to errors in load balancing
     decisions.
