    sys/amd64/amd64      pmap.c 
    sys/i386/i386        pmap.c 
  Log:
  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().
