Will do! I guess I should do the patch against the for-next branch of the
dma-mapping tree. But that branch does not have the s390 support patches (yet?).
To fix it I need both e67a5ed1f86f and 64e1f0c531d1 "s390/mm: force
swiotlb for protected virtualization" (Halil Pasic, 2018-09-13). Or
should I wait for e67a5ed1f86f landing in mainline?

I've rebased the dma-mapping for-next branch to latest mainline as of
today that has both commits.
