Patch from Richard Purdie
This patch moves a large chunk of the sharpsl_pm driver to
arch/arm/common so that it can be reused on other devices such as the
SL-5500 (collie). It also abstracts some functions from the core into
the machine and platform specific parts of the driver to aid reuse.

Unfortunately, using PAGE_SHIFT in asm/arch/memory.h is unsafe, and we
can't include asm/page.h into this file because then we have a circular
dependency. Move the offending code to arch/arm/common/sa1111.c
instead.

This avoids a BUG_ON with kref.c when SA1111 tries to register
a driver with an unregistered bus type.

This allows us to eliminate the casts in the drivers, and eventually
remove the use of the device_driver function pointer methods for
platform device drivers.

Patch from Richard Purdie
The Sharp SL-Cxx00 models have a combined power control for the SD
and CF slot 0. This patch adds hooks to the scoop driver to allow
machines to provide a custom control function for this and such a
function is added for spitz/akita/borzoi.
It also moves the gpio init code into the machine files as this
is machine dependent and differs between some models. A couple of
warnings when compiling for collie are also fixed.

I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.
In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch. This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other. So if any
hunk rejects or gets in the way of other patches, just drop it. My scripts
will pick it up again in the next round.

In PM v1, all devices were called at SUSPEND_DISABLE level. Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.
Since this is obsolete infrastructure which is no longer necessary,
we can remove it. Here's an (untested) patch to do exactly that.

It's pointless to include mach-types.h if you're not going to use
anything from it. These references were removed as a result of:

This patch updates the PCMCIA pxa2xx_sharpsl driver to support multiple scoop
devices by adding a scoop to pcmcia slot mapping structure. It adds platform
support for poodle, is known to work on spitz (which is dual slot) and
should also support collie with a minor amount of further work.

This is part of Thomas Gleixner's generic IRQ patch, which converts
ARM to use the generic IRQ subsystem. Here, we wrap calls to
desc->handler() in an inline function, desc_handle_irq(). This
reduces the size of Thomas' patch since the changes become more
localised.

When DMA bounce buffers were unmapped and the data was memcpy'd to
the original buffer, we were not ensuring that the data was written
to RAM. This means that there was the potential for page cache
pages to have different cache states depending whether they've been
bounced or not.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
