The migration code will not look at a VMStateDescription's minimum_version_id_old field unless that VMSD has set the load_state_old field to something non-NULL. (The purpose of minimum_version_id_old is to specify what migration version is needed for the code in the function pointed to by load_state_old to be able to handle it on incoming migration.) We have exactly one VMSD which still has a load_state_old, in the PPC CPU; every other VMSD which sets minimum_version_id_old is doing so unnecessarily. Delete all the unnecessary ones. Commit created with: sed -i '/\.minimum_version_id_old/d' $(git grep -l '\.minimum_version_id_old') with the one legitimate use then hand-edited back in.
