__get_free_pages() is strange interface:

It has underscores, yet get_free_pages() does not exists.

It returns long when most people need pointer.

(And it takes order, when many people want to pass size).

What about creating void *get_free_pages(flags, order) version, then
slowly converting users to it?

Remove hand-coded get_order() from page_alloc.c.
