Whatever makes sense... but I'll let the s390 bios maintainers decide.

Speaking of which: Please do keep Thomas on cc:...

[This is probably a bit late for 4.0, as softfreeze is next Tuesday and
pull requests for master need to be on-list by then... speaking of pull
requests: I'd prefer to queue this via a pull request from the bios
maintainers rather than picking the patches myself, if possible.]
