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.
