New Revision: 349070
URL: https://svnweb.freebsd.org/changeset/base/349070
Log:
Previously, when pmap_remove_pages() destroyed a dirty superpage mapping,
it only called vm_page_dirty() on the first of the superpage's constituent
4KB pages. This revision corrects that error, calling vm_page_dirty() on
all of superpage's constituent 4KB pages.
