The sharpsl_pcmcia_ops structure gets passed into
sa11xx_drv_pcmcia_probe, where it gets accessed at run-time,
unlike all other pcmcia drivers that pass their structures
into platform_device_add_data, which makes a copy.
This means the gcc warning is valid and the structure
must not be marked as __initdata.
Without this patch, building collie_defconfig results in:
drivers/pcmcia/pxa2xx_sharpsl.c:22:31: fatal error: mach-pxa/hardware.h: No such file or directory
compilation terminated.

This is a pretty significant branch. It's the introduction of the
first multiplatform support on ARM, and with this (and the later
branch) merged, it is now possible to build one kernel that contains
support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
platforms will be convered over in the next few releases.
Two critical last things had to be done for this to be practical and
possible:
* Today each platform has its own include directory under
mach-<mach>/include/mach/*, and traditionally that is where a lot of
driver/platform shared definitions have gone, such as platform data
structures. They now need to move out to a common location instead,
and this branch moves a large number of those out to
include/linux/platform_data.
* Each platform used to list the device trees to compile for its
boards in mach-<mach>/Makefile.boot.
Both of the above changes will mean that there are some merge
conflicts to come (and some to resolve here). It's a one-time move and
once it settles in, we should be good for quite a while. Sorry for the
overhead.

This is a large branch that contains a handful of different cleanups:
- Fixing up the I/O space remapping on PCI on ARM. This is a series
from Rob Herring that restructures how all pci devices allocate I/O
space, and it's part of the work to allow multiplatform kernels.
- A number of cleanup series for OMAP, moving and removing some
headers, sparse irq rework and in general preparation for
multiplatform.
- Final removal of all non-DT boards for Tegra, it is now
device-tree-only!
- Removal of a stale platform, nxp4008. It's an old mobile chipset
that is no longer in use, and was very likely never really used with
a mainline kernel. We have not been able to find anyone interested
in keeping it around in the kernel.
- Removal of the legacy dmaengine driver on tegra
+ A handful of other things that I haven't described above.

Use pci_stop_and_remove_bus_device() like most other hotplug drivers
rather than the special-purpose "behind_bridge" variant. This just
means we have to iterate through all the devices downstream of the
bridge ourselves, which is the same thing pci_stop_behind_bridge()
did.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system
Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h
Move die() and related bits.
(6) asm/auxvec.h
Move AT_VECTOR_SIZE_ARCH here.
Other arch headers are created as needed on a per-arch basis."
Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..

Pull ARM platform updates from Russell King:
"This covers platform stuff for platforms I have a direct interest in
(iow, I have the hardware). Essentially:
- as we no longer support any other Acorn platforms other than RiscPC
anymore, we can collect all that code into mach-rpc.
- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0
dependencies, fix various minor issues
- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
for SIR transmissions as well as FIR
- rework sa1111 support for genirq, and irq allocation
- fix sa1111 IRQ support so it works again
- use sparse IRQ support
After this, I have one more pull request remaining from my current
set, which I think is going to be the most problematical as it
generates 8 conflicts."

Russell.

This patches fixes two things:
* Use gpio_valid function to check gpio before usage
This must be done after 63b4c29678 which uses -EINVAL for unused pin's
* Use gpio_to_irq to convert gpio's to irq
The driver assumed a 1:1 mapping between gpio and irq numbers. This is no
longer true after d0fbda9add.

ARM: at91/pm_slowclock: rename register to named define
ARM: at91/ST: remove not needed casts
ARM: at91: make ST (System Timer) soc independent
ARM: at91: make matrix register base soc independent
ARM: at91/at91x40: remove use of at91_sys_read/write
Based on top of the at91/9x5, rmk/for-armsoc, at91/device-board,
at91/pm_cleanup and at91/base.

The old pci_remove_behind_bridge actually do stop and remove.
Make the name reflect that to reduce confusion.

Lubbock is just another SA1111 socket driver, so now that Kconfig has
better control of which files get built, we can sanitize the build
for this.

sa11xx_base.c is currently built when either PCMCIA_SA1100 or
PCMCIA_SA1111 are selected. Let's move the logic into Kconfig.

sa1111_set_io() already contains the necessary locking within itself
to safely change the state of a set of GPIOs. There's no need for
callers to protect this by disabling IRQs themselves.

Pass along the sa1111_pcmcia_configure_socket() failure code to
higher levels, rather than just returning zero.

soc_common already initializes state.wrprot to zero, so explicitly
setting wrprot to zero in the socket drivers has no additional effect.

Now that we use gpios and gpio_to_irq() etc to manage the various card
status signals within soc_common, and all socket drivers are converted,
these functions are no longer used. We can now get rid of these helper
functions.
