  Log:
  MFC revision 1.552
    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, i.e., I've seen no bug reports in the last two
    years that are helped by this printf().
