It seems I've overlooked an important piece of this submission: one cannot apply the hint to all the anonymous mapping regardless of address range. For KSM I'd rather either have a possibility to hint all the anonymous mappings, or, as it was suggested previously, be able to iterate over existing mappings using some (fd-based?) API.
