   - Remove the old smp cpu topology specification with a new, more flexible
     tree structure that encodes the level of cache sharing and other
   - Provide several convenience functions for creating one and two level
     cpu trees as well as a default flat topology.  The system now always
     has some topology.
   - On i386 and amd64 create a seperate level in the hierarchy for HTT
     and multi-core cpus.  This will allow the scheduler to intelligently
     load balance non-uniform cores.  Presently we don't detect what level
     of the cache hierarchy is shared at each level in the topology.
   - Add a mechanism for testing common topologies that have more information
     than the MD code is able to provide via the kern.smp.topology tunable.
     This should be considered a debugging tool only and not a stable api.
