If I call get_user_pages() on some pages owned by a process, and then the process exits,
are the pages still pinned, or is there some kind of automatic cleanup?

get_user_pages() will pin the pages for you. You now own the additional
refcount on those pages. You must run put_page() against each page to
avoid leaking them.
