Its already assumed that the PageActive flag is clear on the input
page, hence page_lru(page) will pick the base LRU for the page. In
the same way page_lru(page) will pick active base LRU, once the
flag PageActive is set on the page. This change of LRU list should
happen implicitly through the page flags instead of being hard
coded.
