[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.
