  SVN rev 190239 on 2009-03-22 04:32:05Z by alc
  
  In general, the kernel virtual address of the pml4 page table page that is
  stored in the pmap is from the direct map region.  The two exceptions have
  been the kernel pmap and the swapper's pmap.  These pmaps have used a
  kernel virtual address established by pmap_bootstrap() for their shared
  pml4 page table page.  However, there is no reason not to use the direct
  map for these pmaps as well.
