On s390 systems (aka mainframes), it has classic channel devices for networking and permanent storage that are currently even more common than PCI devices. 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 depend PCMCIA on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset. ------ ld: drivers/pcmcia/cistpl.o: in function `set_cis_map': cistpl.c:(.text+0x1202): undefined reference to `ioremap' ld: cistpl.c:(.text+0x13b0): undefined reference to `iounmap' ld: cistpl.c:(.text+0x14a6): undefined reference to `iounmap' ld: cistpl.c:(.text+0x1544): undefined reference to `ioremap' ld: drivers/pcmcia/cistpl.o: in function `release_cis_mem': cistpl.c:(.text+0x3f14): undefined reference to `iounmap' ------ Besides, many other Kconfig option, e.g IPWIRELESS, PCMCIA_PCNET, PCMCIA_FMVJ18X, PCMCIA_SMC91C92 which depends on PCMCIA also will cause compiling error if enabled. ------ ERROR: modpost: "iounmap" [drivers/tty/ipwireless/ipwireless.ko] undefined!
