  Log:
  Make code match comment: make the smallest unit of page allocation
  from OpenFirmware be 16 pages to avoid fragmentation in the list
  of mappings returned when the kernel requests it in pmap_bootstrap.
  
  This allows a static buffer to be used when obtaining the existing
  mappings - very useful on the G5 when random physical pages can't
  be grabbed because they can't be BAT-mapped.
