Nevertheless, getting rid of all those needless asm/pgalloc.h includes
is something worth doing anyway.  This isn't the first time not being
able to get at mm_struct / vma_area_struct in asm/pgtable.h has been
a problem.

So I think its worth sorting this out anyway, independent of the
rmap changes.
