Well, I think his patch is orthogonal to mine. My ultimate target
is IA64 and it will only support node-sized memory hotplugging.
If you need fine-grained memory resizing, that shouldn't be hard to
do. As others have pointed out, per section hotremovable is not as
easy as per zone one, but we've done a similar thing for hugetlbfs
support. Look for PG_again in Takahashi's patch.
