The duplicate file "include/asm-arm/arch-at91rm9200/entry-macro.S" can
be removed - it was already moved to include/asm-arm/arch-at91/.

Fix 3 small typo's - two in comments, and the incorrect clock was

f80dff9da0 [ARM] 4185/2: entry: introduce get_irqnr_preamble and arch_ret_to_user
get_irqnr_preamble allows machines to take some action before entering the
get_irqnr_and_base loop.  On iop we enable cp6 access.

arch_ret_to_user is added to the userspace return path to allow individual
architectures to take actions, like disabling coprocessor access, before
the final return to userspace.

Per Nicolas Pitre's note, there is no need to cp_wait on the return to user
as the latency to return is sufficient.

48adbcf33b [ARM] 4220/1: S3C24XX: DMA system initialised from sysdev
This patch gets the DMA system for the S3C24XX
ready for the S3C2443, which requires 6 dma channels
at a different stride, and different base IRQ.

The DMA system is now initialised from the same
drivers which apply the DMA mappings, as well
as removing the DMA sysdev intialisation out of
the main init code (which is now being called
from a sysdev probe, so cannot add a new sysdev)

bc43fd40ea [ARM] 4090/2: avoid clash between PXA and SA1111 defines
The Lubbock platform uses both a PXA25x and a SA1111 at the same time.
Both chips have the same "Serial Audio Controller" registers although
the SA1111 one is never expected to be used in preference to the PXA25x
one. So let's disable the SA1111 defines whenever compilation is for a
PXA architecture and make the PXA defines always defined.

This removes a bunch of "already defined" warnings as well since the
current hack to prevent them depended on include ordering which wasn't
always right.

While at it, clean up the SA1111 defines allowing to get rid of the
__CCREG() macro.
