Use the migration entries for page migration This modifies the migration code to use the new migration entries. It now becomes possible to migrate anonymous pages without having to add a swap entry. We add a couple of new functions to replace migration entries with the proper ptes. We cannot take the tree_lock for migrating anonymous pages anymore. However, we know that we hold the only remaining reference to the page when the page count reaches 1.
