[PATCH] solve config broken: undefined reference to `online_page'
Memory hotplug code of i386 adds memory to only highmem. So, if CONFIG_HIGHMEM is not set, CONFIG_MEMORY_HOTPLUG shouldn't be set. Otherwise, it causes compile error. In addition, many architecture can't use memory hotplug feature yet. So, I introduce CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG.
