With gigantic pages it may not be true that struct page structures
are contiguous across the entire gigantic page. The mem_map_offset
function is used here in place of direct pointer arithmetic to
correct for this.

We're just eliminating mem_map_offset().  Please use nth_page()
instead.That's good to know. I will include that in v2.

Thanks Doug and Matthew.  I will take a closer look at this series soon.

It seems like this patch is a fix independent of the series.  If so, I
would suggest sending separate to make it easy for backports to stable.
