  SVN rev 209861 on 2010-07-09 19:38:30Z by alc
  
  Add support for the VM_ALLOC_COUNT() hint to vm_page_alloc().  Consequently,
  the maintenance of vm_pageout_deficit can be localized to just two places:
  vm_page_alloc() and vm_pageout_scan().
  
  This change also corrects an off-by-one error in the maintenance of
  vm_pageout_deficit.  Historically, the buffer cache functions, allocbuf()
  and vm_hold_load_pages(), have not taken into account that vm_page_alloc()
  already increments vm_pageout_deficit by one.
