I didn't change anything I didn't need to.  File pages go onto the
LRU list, so I need to change the LRU code to handle arbitrary-sized
folios instead of pages which are either order-0 or order-9.  Every
function that I convert in this patchset is either used by another
function in this patchset, or by the fs/iomap conversion that I have
staged for the next merge window after folios goes in.
