get_page() is different - it elevates the page count of a page of
_arbitrary order_. put_page() on the other hand does a __free_page()
[unconditional order 0]. This is a speciality of the Buddy allocator (you
can get a reference to a page through it's pointer without knowing the
order of the page, but you cannot free it without knowing the order), and
it's bad naming (i believe that particular naming is my fault).
