  SVN rev 194936 on 2009-06-25 01:33:51Z by jeff
  
   - Use DPCPU for SCHED_STATS.  This is somewhat awkward because the
     offset of the stat is not known until link time so we must emit a
     function to call SYSCTL_ADD_PROC rather than using SYSCTL_PROC
     directly.
   - Eliminate the atomic from SCHED_STAT_INC now that it's using per-cpu
     variables.  Sched stats are always incremented while we're holding
     a spinlock so no further protection is required.
