This has nothing to do with my patch. The reported error exists in the
current kernel as long as on s390 you set CONFIG_PCI=n and enable driver
Kconfig options like PCMCIA, AL_FIC, ALTERA_TSE, etc which invokes ioremap()
or devm_ioremap_xx, devm_memremap_xx, etc in driver code. Below patch can
fix the one happening in drivers/pcmcia/cistpl.c. I will post patches to
fix these I found when addressing lkp reported error.

Subject: [PATCH] pcmcia : make PCMCIA depend on HAS_IOMEM
Content-type: text/plain
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: 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
fail to build because of the same reason.
