S390: all HAS_IOMEM build failures in one fell swoop

S390: all HAS_IOMEM build failures in one fell swoop

[Randy Dunlap]

On ARCH=s390:

By disabling CONFIG_PCI and hence also disabling CONFIG_HAS_IOMEM
(after having done 'make ARCH=s390 allmodconfig'),
we can see all of the drivers that use IOMEM-related interfaces
without mentioning that they do so (in their respective Kconfig files).

This should catch all of them, instead of various randconfig builds
catching a few of them at a time.
(I'm not trying to pick on arch/s390/ here -- more on the piecemeal
randconfig approach of some 'bot'. :)


I have grouped them by subsystem (more or less).
