From: Michal Hocko <mho...@suse.cz>
After introducing CONFIG_HAVE_BOOTMEM_INFO_NODE Kconfig option, the related arch
specific functions become confusing, remove them.
Guys who want to implement memory-hotplug feature on such archs for this part
should look into register_page_bootmem_info_node() and flesh out from top to
end.
