  Log:
  Remove bogus increment of re-hashed PTEG index. This snuck in with r1.12 of
  pmap.c, and is potentially the cause of hangs reported on machines with a
  small amount of memory. On machines with sufficient RAM, and without a lot
  of processes running, this situation would probably never occur.
  
  Testing is still incomplete, but it is obviously wrong so remove the
  offending code now.
  
  The issue of what to do when both the primary and secondary hash overflow
  is still open.
