I can confirm these reproted errors have nothing to do with my patch. I
got a s390 system and build the latest kernel from linus's master branch
with above config, all these failures have been existing there. I have
made patches to fix them by adding dependency on HAS_IOMEM for drivers.

I would suggest lkp adjusts script to test the base firstly so that a
reliable base is provided to avoid confusion.

Thanks
Baoquan
