  Log:
  MFC Revision 1.538:
    Remove stale KSE code.
  
  MFC Revision 1.551:
    In general, bits in the page directory entry (PDE) and the page table
    entry (PTE) have the same meaning.  The exception to this rule is the
    eighth bit (0x080).  It is the PS bit in a PDE and the PAT bit in a
    PTE.  This change avoids the possibility that pmap_enter() confuses a
    PAT bit with a PS bit, avoiding a panic().
  
    Eliminate a diagnostic printf() from the i386 pmap_enter() that serves
    no current purpose.
  
  MFC Revision 1.559:
    Eliminate a comment that became stale after revision 1.540.
  
  MFC Revision 1.575:
    Finish the PG_NX support at the pmap level.
  
  MFC Revision 1.582:
    Eliminate the misuse of PG_FRAME to truncate a virtual address
    to a virtual page boundary.
