    sys/amd64/amd64      mp_machdep.c 
   - Use the correct test in the ipi bitmask handler for IPI_PREEMPT so that
     we actually issue preemptions.
   - Remove the #ifdef IPI_PREEMPTION so it is always compiled in.  Leave
     the option which optionally enables support in sched_4bsd.  sched_ule.c
     will soon use this functionality as a run time rather than compile time
   - Compare against the idlethread rather than the priority.  There are some
     idle prio tasks that we can preempt.
