Now we are using register_e820_active_regions() instead of add_active_range() directly. So end_pfn could be different between the value in early_node_map to node_end_pfn. So we need to make shrink_active_range() smarter. shrink_active_range() is a generic MM function in mm/page_alloc.c but it is only used on 32-bit x86. Should we move it back to some file in arch/x86?
