PG_referenced means "The page has been recently accessed." I think we can
also check if a page has been accessed recently using reverse-mapping and
pte_young(), though using PG_referenced is more efficient. I don't know if
performance is the only reason we use PG_referenced flag. Thanks.
Regards,
Hao Lee
