  Modified files:
    sys/amd64/amd64      pmap.c 
  Log:
  Change pmap_extract() and pmap_extract_and_hold() to use PG_FRAME rather
  than ~PDRMASK to extract the physical address of a superpage from a PDE.
  The use of ~PDRMASK is problematic if the PDE has PG_NX set.  Specifically,
  the PG_NX bit will be included in the physical address if ~PDRMASK is used.
