Thank you for the report and patch.

This is linux-next only. Its a conflict between my kvms390 queue and
Martins s390 queue. We cannot apply this directly as it would break
the build of my tree when not merged in next. (and it does not apply
on Martins tree).

I will have a look how to fix that up.
