This series gets rid of MIGRATEPAGE_UNMAP, to then convert the remaining MIGRATEPAGE_SUCCESS usage to simply use 0 instead. Not sure if it makes sense to split the second patch up, a treewide cleanup felt more reasonable for this simple change in an area where I don't expect a lot of churn. Briefly tested with virtio-mem in a VM, making sure that basic page migration keeps working.
