Hence it could have a fully functional s390 kernel with CONFIG_PCI=n, then the relevant iomem mapping functions [including ioremap(), devm_ioremap(), etc.] are not available. Here let OPEN_DICE depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset: ------ ERROR: modpost: "devm_memremap" [drivers/misc/open-dice.ko] undefined!
