  SVN rev 202836 on 2010-01-22 20:52:31Z by jhb
  
  MFC 189610:
  Eliminate the last use of the recursive mapping to access user-space page
  table pages.  Now, all accesses to user-space page table pages are
  performed through the direct map.  (The recursive mapping is only used
  to access kernel-space page table pages.)
  
  Eliminate the TLB invalidation on the recursive mapping when a user-space
  page table page is removed from the page table and when a user-space
  superpage is demoted.
