The linux-next commit "x86: mm: avoid allocating struct mm_struct on the
stack" [1] introduced a compilation error with "arm64: mm: convert
mm/dump.c to use walk_page_range()" [2]. Fixed it by using the new API.

Actually this was in the patch I originally posted - somehow it got
lost when Andrew picked it up.

I'm assuming Andrew will queue this alongside the others.

Thanks,
