  Log:
  Checkpoint of a new physical memory backed object type, that does not
  have pv_entries.  This is intended for very special circumstances,
  eg: a certain database that has a 1GB shm segment mapped into 300
  processes.  That would consume 2GB of kvm just to hold the pv_entries
  alone.  This would not be used on systems unless the physical ram was
  available, as it's not pageable.
  
  This is a work-in-progress, but is a useful and functional checkpoint.
  Matt has got some more fixes for it that will be committed soon.
