  Modified files:
    sys/kern             sched_ule.c 
  Log:
   - Share scheduler locks between hyper-threaded cores to protect the
     tdq_group structure.  Hyper-threaded cores won't really benefit from
     seperate locks anyway.
   - Seperate out the migration case from sched_switch to simplify the main
     switch code.  We only migrate here if called via sched_bind().
   - When preempted place the preempted thread back in the same queue at
     the head.
   - Improve the cpu group and topology infrastructure.
