SVN rev 214377 on 2010-10-26 14:59:35Z by nwhitehorn
MFC r212360:
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.
