Add pseudo-DMA by FIQ to the S3C24XX SPI driver. This allows the driver
to get DMA-like performance where there are either no free DMA channels or
when doing transfers that required both TX and RX data paths.
Since this patch requires the addition of an assembly file to hold the FIQ
code, we rename the module (instead of adding a rename of the .c file to
this patch). We expect most users are loading this via udev and thus
there should be no change to the userland configuration.

This driver was merged before the ep93xx core support was added
for the keypad clock and acquiring/releasing the necessary gpio's.
Now that the proper support is in the ep93xx core this driver
needs to be updated to work correctly.
Summary of changes:
1) Remove some unused members from the platform data.
2) Remove the custom KEY macro and use the ones available in
<linux/input/matrix_keypad.h>
3) Remove the keypad_{readl/writel} macros and just use
__raw_{readl/writel} directly.
4) Update the clk_set_rate() call to work with the core support.
5) Cleanup the probe routine and remove some unneeded messages.
6) Use the ep93xx core functions to acquire and release the gpio's.
7) Fix the clk_get() call to get the keypad clock.

Allow the use of another DMA controller driver in atmel-mci sd/mmc driver.
This adds a generic dma_slave pointer to the mci platform structure where
we can store DMA controller information. In atmel-mci we use information
provided by this structure to initialize the driver (with new helper
functions that are architecture dependant).
This also adds at32/avr32 chip modifications to cope with this new access
method.

The Kconfigs for in-tree floating point emulation do not allow building
as modules. That leaves the Acorn FPEmulator module. I found two public
releases of this as a binary module for 2.1 and 2.2 kernels, optimized
for ARMV4.[1] If there is a resurgence of interest in this, the symbols
can always be re-exported.
This allows the EXPORT_SYMBOL_ALIAS() hack to be removed. The ulterior
motive here is that EXPORT_SYMBOL_ALIAS() makes it harder to sort the
resulting kernel symbol tables. Sorted symbol tables will allow faster
symbol resolution during module loading.
Note that fp_send_sigs() and fp_printk() are simply aliases for existing
exports and add no obvious value. Similarly fp_enter could easily be
renamed to kern_fp_enter at the point of definition. Therefore removing
EXPORT_SYMBOL_ALIAS will not serve as a material obstacle to re-adding
the exports should they be desired in future.
Build tested only.

Commit 023bf6f "linker script: unify usage of discard definition"
changed the linker scripts for all architectures except for ARM.
I can find no discussion about this ommision, so here are the changes
for ARM.
These changes are exactly parallel to the ia64 case.
"ia64 is notable because it first throws away some ia64 specific
subsections and then include the rest of the sections into the final
image, so those sections must be discarded before the inclusion."
Not boot-tested. In build testing, the modified linker script generated
an identical vmlinux file.
[I would like to be able to rely on this unified discard definition.
I want to sort the kernel symbol tables to allow faster symbol
resolution during module loading. The simplest way appears to be
to generate sorted versions from vmlinux.o, link them in to vmlinux,
_and discard the original unsorted tables_.
This work is driven by my x86 netbook, but it is implemented at a
generic level. It is possible it will benefit some ARM systems also.]

There's no point having the hardware support background operations
if we issue a cache operation, and then wait for it to complete
before calculating the address of the next operation. We gain no
advantage in the cache controller stalling the bus until completion.
What we should be doing is using the 'wait' time productively by
calculating the address of the next operation, and only then waiting
for the previous operation to complete. This means that cache
operations can occur in parallel with the CPU calculating the next
address.

setting the PCMCIA and LCD timings. Adding ifdefs to these drivers to
select cpufreq_get() or some other interface adds confusion. Making
these drivers use some other interface for the normal paths and cpufreq
stuff for the cpufreq notifier is insane as well.
(Why x86 can't provide a version of cpufreq_get() which returns the
CPU frequency when CPUFREQ is disabled is beyond me, rather than
requiring a dummy zero-returning cpufreq_get(). Especially as they
do:
unsigned long khz = cpufreq_get(cpu);
if (!khz)
khz = tsc_khz;
In other words, if CPUFREQ is disabled, get it from tsc_khz - why
not provide a dummy cpufreq_get() which returns tsc_khz?)

The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030
for OMAP3. The common modules like RTC, Regulator creates opportunity
to re-use the most of the code from twl4030.
This patch renames few common drivers twl4030* files to twl* to enable
the code re-use.

The power scripts optimisation was mainly done by:
Tero Kristo <tero.kristo@nokia.com> and
Arnaud Mandy <ext-arnaud.2.mandy@nokia.com>
I'm only refactoring and testing it against the mainline kernel.

Anders Grafström reports that footbridge fails to build after 1c4a4f4.
Fix this by adding the necessary definitions for __pfn_to_bus and
__bus_to_pfn.
