ec14d7964b [ARM] Export dma_channel_active()
dma_channel_active() is used by some modules and is part of our
DMA API, so export it.

95ba9fb06b [ARM] Remove definition of MAX_DMA_CHANNELS to zero
Since we now only build arch/arm/kernel/dma.c on machine types
which set ISA_DMA_API, we don't need to define MAX_DMA_CHANNELS
to 0 to indicate this - this definition becomes superfluous.
Remove it.

6842b92992 [ARM] Use core_initcall() to initialise ARM DMA
There's no need to have DMA initialised at the same time as
interrupts.  Move it to a core_initcall().

7cdad48297 [ARM] Remove '__address' from scatterlist and convert to DMA API
The old __address element in struct scatterlist remained from older
kernels because the ARM DMA emulation code made use of it.  Move
this field into struct dma_struct, and convert DMA emulation code
to setup a SG entry as required.

Also, convert DMA emulation code to use the new DMA API rather
than the PCI DMA API.

333c9624b7 [ARM] Move ISA DMA bus_to_virt() out of set_dma_addr()
Allow the compiler to optimise the bus_to_virt(virt_to_bus())
transformation in the ARM ISA DMA interface.

78ff18a412 [ARM] Cleanup ARM includes
arch/arm/kernel/entry-armv.S has contained a comment suggesting
that asm/hardware.h and asm/arch/irqs.h should be moved into the
asm/arch/entry-macro.S include.  So move the includes to these
two files as required.

Add missing includes (asm/hardware.h, asm/io.h) to asm/arch/system.h
includes which use those facilities, and remove asm/io.h from
kernel/process.c.

Remove other unnecessary includes from arch/arm/kernel, arch/arm/mm
and arch/arm/mach-footbridge.

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!
