OK, consider that patch withdrawn.  In its place is the one below.  It's in
UML arch code, so it needs to be applied after UML itself.  It disables
'root=/dev/ubdxx' in UML for the time being.

The root_dev_names array looks like it can be eliminated entirely, as long
as the gendisk list is populated before checksetup.  This means either there
needs to be a before_setup_initcall or the calculation of the rootdev kdev_t
needs to be split out from the argument parsing and put in a late initcall.
I don't know if that breaks anything.

If that is reasonable, I can start laying the groundwork.
