This driver does an unconditional read of io space during module init which
causes a bad dereference on ARM. It looks to me like this is an x86 only
drivers, so restrict it to only compile on x86.

The __iomem annotation is to be used together with pointers used
in iowrite32() but not for pointers returned by kzalloc().
For more details see [1] and [2].
This patch will remove the following sparse warning (i.e. when
copiling with "make C=1"):
* warning: incorrect type in assignment (different address spaces)

2nd round of GPIO changes for v3.3 merge window
* tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6:
GPIO: sa1100: implement proper gpiolib gpio_to_irq conversion
gpio: pl061: remove combined interrupt
gpio: pl061: convert to use generic irq chip
GPIO: add bindings for managed devices
ARM: realview: convert pl061 no irq to 0 instead of -1
gpio: pl061: convert to use 0 for no irq
gpio: pl061: use chained_irq_* functions in irq handler
GPIO/pl061: Add suspend resume capability
drivers/gpio/gpio-tegra.c: use devm_request_and_ioremap
The existing gpio_to_irq() implementation on sa1100 only translates
validly for internal GPIOs. Since this sub-arch enables GPIOLIB
support, this results in buggy translations for non-internal GPIOs.
Get rid of the private gpio_to_irq() implementation, replacing it
with the .to_irq method in the sa1100 gpio chip instead.

STMPE801 is a GPIO expander. GPIO registers for 801 are slightly different from other
variants. This patch adds support for STMPE801 in stmpe gpio driver.

and it fixes the build error in the arch/x86/kernel/microcode_core.c
file, that the merge did not catch.
The microcode_core.c patch was provided by Stephen Rothwell
<sfr@canb.auug.org.au> who was invaluable in the merge issues involved
with the large sysdev removal process in the driver-core tree.

Drivers should not have a dependency on NR_IRQS. Doing so may break with
SPARSE_IRQ enabled. As there are no in kernel users of the pl061 which
have multiple instances with their interrupts combined to a single parent
interrupt, remove this functionality. If this capability is needed later,
it could be supported more cleanly by just using a devicetree property.

Convert the pl061 irq_chip code to use the generic irq chip code.
This has the side effect of using 32-bit accesses rather than 8-bit
accesses to interrupt registers. The h/w TRM and testing seem to indicate
this is fine.
