    sys/i386/i386        pmap.c 
  Log:
  Using an idea from Stephan Uphoff, use the empty pte's that correspond
  to the unused kva in the pv memory block to thread a freelist through.
  This allows us to free pages that used to be used for pv entry chunks
  since we can now track holes in the kva memory block.
