  Log:
  Specifically panic() in the case where pmap_insert_entry() fails to
  get a new pv under high system load where the available pv entries
  have been exhausted before the pagedaemon has a chance to wake up
  to reclaim some.
  
  Prior to this, the NULL pointer dereference ended up causing
  secondary panics with rather less than useful resulting tracebacks.
