    sys/i386/i386        pmap.c 
  Eliminate spurious "Approaching the limit on PV entries, ..."
  warnings.  Specifically, whenever vm_page_alloc(9) returned NULL to
  get_pv_entry(), we issued a warning regardless of the number of pv
  entries in use.  (Note: The older pv entry allocator in RELENG_6 does
  not have this problem.)
  Reported by:    Jeremy Chadwick
  Eliminate the direct call to pagedaemon_wakeup() by get_pv_entry().
  This was a holdover from earlier times when the page daemon was
  responsible for the reclamation of pv entries.
