From: Yasuaki Ishimatsu <isimatu.yasuaki@xxxxxxxxxxxxxx>
add_memory() hot adds a physical memory. But remove_memory does not
hot remove a phsical memory. It only offlines memory. The name
confuse us.
So the patch renames remove_memory() to offline_memory(). We will
use rename_memory() for hot removing memory.
