Hi robot,

Instead of hit & miss with s390 randconfigs, you could do what I did:
(all for arch/s390/):

$ make allmodconfig
$ scripts/config -d PCI  ## this also disables HAS_IOMEM
$ make oldconfig
$ make all

The latter gives a full list of drivers etc. that use iomemp/ioremap 
etc. as well as dev_io* variants instead of just a few random ones.
