This patch just performs a global cleanup in DMA mapping implementation
for ARM architecture. Some of the tiny helper functions have been moved
to the caller code, some have been merged together.

This patch modifies dma-mapping implementation on ARM architecture to
use common dma_map_ops structure and asm-generic/dma-mapping-common.h
helpers.

This patch removes the need for offset parameter in dma bounce
functions. This is required to let dma-mapping framework on ARM
architecture use common, generic dma-mapping helpers.

This patch converts dma_alloc/free/mmap_{coherent,writecombine}
functions to use generic alloc/free/mmap methods from dma_map_ops
structure. A new DMA_ATTR_WRITE_COMBINE DMA attribute have been
introduced to implement writecombine methods.

This patch converts all dma_sg methods to be generic (independent of the
current DMA mapping implementation for ARM architecture). All dma sg
operations are now implemented on top of respective
dma_map_page/dma_sync_single_for* operations from dma_map_ops structure.

Ingo,
Here is the Joerg's irq_remap_ops patchset updated for the latest -tip.
Simplified some of the naming conventions to follow the irq_remapping
terminology. There are still some if (irq_remapping_enabled) checks in

Anyway Joerg, how do you want to handle this? Do you want to pick up
1/2/3 all of them in your tree? If so, 2nd patch should be on top of
some samsung topic stuff.
Since patch 2 only applies to the Samsung tree,
Ping. Does this approach look like it could satisfy your desire for a
more integrated group layer? I'd really like to move VFIO forward,
we've been stalled on this long enough. David Woodhouse, I think this
provides the quirking you're looking for for device like the Ricoh, do
you have any
