[SPARC64]: Allow CONFIG_MEMORY_HOTPLUG to build.
online_page() is straightforward, and then add a dummy remove_memory() that returns -EINVAL just like i386. There is no point in implementing remove_memory() since __remove_pages() has no implementation either. Signed-off-by: David S. Miller <davem@davemloft.net>
