Okay, it turned out to be trickier than I thought to manually call a
get_page_and_type().  Seems like I missed a few conditions checks
still.  I ended up wrapping the get_page_from_l1e and higher functions
with another parameter that lets me bypass the external domain
mappings not counting code.

Thanks for the help!
