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.
