Add in r568323 and 568879. The approved patch

lacked updates to the doccos and so really shouldn't
have been approved as is, but what the heck, so I
went ahead and pulled the doccos changes from the orig
commit anyway. Also, since this is a userland change,
it should really have a CHANGES entry too, so I added
one of those as well :)
