  Log:
  SVN rev 212360 on 2010-09-09 13:32:58Z by nwhitehorn
  
  On architectures with non-tree-based page tables like PowerPC, every page
  in a range must be checked when calling pmap_remove(). Calling
  pmap_remove() from vm_pageout_map_deactivate_pages() with the entire range
  of the map could result in attempting to demap an extraordinary number
  of pages (> 10^15), so iterate through each map entry and unmap each of
  them individually.
