Here are the remaining patches required to support basic forms of
NFSv4 migration. These apply on and have been tested with 3.12-rc5.
NFSv4.1 migration support remains provisional.
There are still some nits to work out about what happens to an
nfs_client once all its nfs_server's are migrated away.
