  Log:
  Correct pmap_copy()'s method for extracting the physical address of a
  2/4MB page from a PDE.  Specifically, change it to use PG_PS_FRAME,
  not PG_FRAME, to extract the physical address of a 2/4MB page from a
  PDE.
  
  Change the last argument passed to pmap_pv_insert_pde() from a
  vm_page_t representing the first 4KB page of a 2/4MB page to the
  vm_paddr_t of the 2/4MB page.  This avoids an otherwise unnecessary
  conversion from a vm_paddr_t to a vm_page_t in pmap_copy().
