    kernel - VM rework part 18 - Cleanup
    
    * Significantly reduce the zone limit for pvzone (for pmap
      pv_entry structures).  pv_entry's are no longer allocated
      on a per-page basis so the limit can be made much smaller.
    
      This also has the effect of reducing the per-cpu cache limit
      which ultimately stabilizes wired memory use for the zone.
    
    * Also reduce the generic pre-cpu cache limit for zones.
      This only really effects the pvzone.
    
    * Make pvzone, mapentzone, and swap_zone __read_mostly.
    
    * Enhance vmstat -z, report current structural use and actual
      total memory use.
    
    * Also cleanup the copyright statement for vm/vm_zone.c.  John Dyson's
      original copyright was slightly different than the BSD copyright and
      stipulated no changes, so separate out the DragonFly addendum.
