This is a preparation patch to batch the page unmapping and moving for the normal pages and THP. In this patch, unmap_and_move() is split to migrate_page_unmap() and migrate_page_move(). So, we can batch _unmap() and _move() in different loops later. To pass some information between unmap and move, the original unused newpage->mapping and newpage->private are used.
