Maybe wrap it into
#if PAGE_OFFSET > 12
#endif
or something like that?
I'm not sure actually why drivers would want to have list of 64k pages,
instead driver could call give_me_pages(size) instead of alloc_pages
and per-arch allocator would return one page or set of pages. This is a
handwaving for now...
