ARCH_POPULATES_NODE_MAP in 3.0 is replaced by HAVE_MEMBLOCK_NODE_MAP in
3.4. add_active_range() is replaced with memblock_set_node(). They do
basically the same thing, but embedding nid field into memblock_region
is much cleaner than a separate early_node_map.
HAVE_MEMBLOCK_NODE_MAP is not selected by default.
See commit 4a2164a7db for more info.
