But for the get_user_pages() case there's no point, is there? The VMA and the virtual address is already available, so trying to find it again through RMAP doesn't much make sense. Users of get_user_pages() don't care about any other mappings (maybe ptrace does, I don't know) only about one single user mapping and one kernel mapping. So using flush_dcache_page() there is an overkill, trying to teach it about anonymous pages is not the real solution, flush_dcache_page() was never meant to be used on anything but file mapped pages.
