Subject: uml ubd driver: allow using up to 16 UBD devices
From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@xxxxxxxx>
With 256 minors and 16 minors used per each UBD device, we can allow the use
of up to 16 UBD devices per UML.
Also chnage parse_unit and leave to the caller (which already do it) the check
for excess numbers, since this is just supposed to do raw parsing.
