  SVN rev 202970 on 2010-01-25 15:50:52Z by jhb
  
  MFC 190239:
  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.
