Ben,

The userspace update_flash script invokes the rtas_flash module. With
upcoming System p servers, the firmware will have the entitlement dates
encoded in it and RTAS will return an error if the entitlement has
expired. All we need from this module is for it to return that new error
which will then be communicated to the user by the update_flash.
