Hi Christian -- You already accepted this patch into s390-next with
these changes as 234eef51a12e2f0f8dfd71cb49d2469d462b1855.  Or am I
missing something else you wanted changed?

This is part of v1 -- v2 of the whole patch set excluded this patch as a
result (among other changes).

I noticed that v2 doesn't fit anymore.  I'll submit a trimmed-down and
re-fit v3 of the patch set once Igor's 'convert -m to QemuOpts' set goes
in (it just got applied to trivial).
