Baoquan He acdbfa0481 pcmcia : make PCMCIA depend on HAS_IOMEM 
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: 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.

menuconfig PCCARD
tristate "PCCard (PCMCIA/CardBus) support"
help
Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
computer. These are credit-card size devices such as network cards,
modems or hard drives often used with laptops computers. There are
actually two varieties of these cards: 16 bit PCMCIA and 32 bit
CardBus cards.
To compile this driver as modules, choose M here: the
module will be called pcmcia_core.
if PCCARD
config PCMCIA
tristate "16-bit PCMCIA support"
depends on HAS_IOMEM
select CRC32
default y
help
This option enables support for 16-bit PCMCIA cards. Most older
PC-cards are such 16-bit PCMCIA cards, so unless you know you're
only using 32-bit CardBus cards, say Y or M here.
To use 16-bit PCMCIA cards, you will need supporting software in
most cases. (see the file <file:Documentation/Changes> for
location and details).
To compile this driver as modules, choose M here: the
module will be called pcmcia.
If unsure, say Y.
config PCMCIA_LOAD_CIS
bool "Load CIS updates from userspace"
depends on PCMCIA
select FW_LOADER
default y
help
Some PCMCIA cards require an updated Card Information Structure (CIS)
to be loaded from userspace to work correctly. If you say Y here,
and your userspace is arranged correctly, this will be loaded
automatically using the in-kernel firmware loader and the hotplug
subsystem, instead of relying on cardmgr from pcmcia-cs to do so.
If unsure, say Y.
config CARDBUS
bool "32-bit CardBus support"
depends on PCI
default y
help
CardBus is a bus mastering architecture for PC-cards, which allows
for 32 bit PC-cards (the original PCMCIA standard specifies only
a 16 bit wide bus). Many newer PC-cards are actually CardBus cards.
To use 32 bit PC-cards, you also need a CardBus compatible host
bridge. Virtually all modern PCMCIA bridges do this, and most of
them are "yenta-compatible", so say Y or M there, too.
If unsure, say Y.

This option enables support for CardBus host bridges. Virtually

Say Y here to include support for ISA-bus PCMCIA host bridges that

Say Y here to enable debugging for the SoC PCMCIA layer.
You will need to choose the debugging level either via the
kernel command line, or module options depending whether
you build the drivers as modules.
The kernel command line options are:
sa11xx_core.pc_debug=N
pxa2xx_core.pc_debug=N
The module option is called pc_debug=N
In all the above examples, N is the debugging verbosity
level.
