I think this is OK but please could you send a followup patch to
extras/mini-os/COPYING which clarifies the situation. Something like
"... Certain files in this directory are licensed under the GPLv2. By
default these are not built and linked into MiniOS however enabling them
will cause the whole work to become covered by the GPL.". Or something
like that (Ian Jackson -- perhaps you have an opinion on the wording?)

Anyway, for this patch:
Acked-by: Ian Campbell <ian.campbell@xxxxxxxxxx>

And applied.
