With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was
broken. PCMCIA depends on __io() returning a valid i/o address, and most
ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This
needs a better fix with a fixed i/o address mapping, but for now we just
restore things to the previous behavior.
This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled,
but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff,
so it doesn't need an io.h.

Rob Herring has done a sweeping change cleaning up all of the mach/io.h includes,
moving some of the oft-repeated macros to a common location and removing a bunch of

These changes are all specific to one board only. We're trying to keep

Even when CONFIG_MULTI_IRQ_HANDLER is selected, the core code
requires the arch_irq_handler_default macro to be defined as
a fallback.
It turns out nobody is using that particular feature as both PXA
and shmobile have all their machine descriptors populated with
the interrupt handler, leaving unused code (or empty macros) in
their entry-macro.S file just to be able to compile entry-armv.S.
Make CONFIG_MULTI_IRQ_HANDLER exclusive wrt arch_irq_handler_default,
which allows to remove one test from the hot path. Also cleanup both

Fix up trivial conflict in arch/arm/mach-imx/mach-scb9328.c
Now most of ARM machines has the alsmot same __clk_get/put() macro
So place it at the arch/arm/include/asm/clkdev.h and remove the reduntant header files
But some machines don't have the same form as above. It can use the machince specific clkdev file by HAVE_MACH_CLKDEV config
Now there are only 3 caese.
1) define the clk structure with clkdev macro => Need to move clk structure to proper header file
arch/arm/mach-versatile/include/mach/clkdev.h
arch/arm/mach-realview/include/mach/clkdev.h
arch/arm/mach-vexpress/include/mach/clkdev.h
arch/arm/mach-integrator/include/mach/clkdev.h
2) export the __clk_get/put function at clock.c
arch/arm/mach-shmobile/include/mach/clkdev.h
3) demuxing the clk source
arch/arm/mach-u300/include/mach/clkdev.h

Convert PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to variables to allow
multi-platform builds. This also removes the requirement for a platform to
have a mach/hardware.h.
The default values for i/o and mem are 0x1000 and 0x01000000, respectively.
Per Arnd Bergmann, other values are likely to be incorrect, but this commit
does not try to address that issue.

There are SoCs where attempting to enter a low power state is ignored,
and the CPU continues executing instructions with all state preserved.
It is over-complex at that point to disable the MMU just to call the
resume path.
Instead, allow the suspend finisher to return error codes to abort
suspend in this circumstance, where the cpu_suspend internals will then
unwind the saved state on the stack. Also omit the tlb flush as no
changes to the page tables will have happened.

Rather than each platform providing its own function to adjust the
zone sizes, use the new ARM_DMA_ZONE_SIZE definition to perform this
adjustment. This ensures that the actual DMA zone size and the
ISA_DMA_THRESHOLD/MAX_DMA_ADDRESS definitions are consistent with
each other, and moves this complexity out of the platform code.

The values of ISA_DMA_THRESHOLD and MAX_DMA_ADDRESS are related; one is
the physical/bus address, the other is the virtual address. Both need
to be kept in step, so rather than having platforms define both, allow
them to define a single macro which sets both of these macros
appropraitely.

To be able to relocate the .bss section at run time independently from
the rest of the code, we must make sure that no GOTOFF relocations are
used with .bss symbols. This usually means that no global variables can
be marked static unless they're also const.
Let's remove the static qualifier from current offenders, or turn them
into const variables when possible. Next commit will ensure the build
fails if one of those is reintroduced due to otherwise enforced coding
standards for the kernel.

This change -- pushing the MFP configuration back into Module files -- is
necessary because some evalboards can be used with multiple modules, where MFP
differs from module to module. Therefore MFP isn't board-specific, but
module-specific and the module should preconfigure itself for the board.
(And there is also the C preprocesor limitation and conflicting #define-s)

The PXA-SPI driver relies on some files / defines which are arm specific
and are within the ARM tree. The CE4100 SoC which is x86 has also the
SPI core.
This patch moves the ssp and spi files from arm/mach-pxa and plat-pxa to
include/linux where the CE4100 can access them.
This move got verified by building the following defconfigs:
cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig
imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig

Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.
This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.
