After moving the the include files there were a few clean-ups:
1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h>
2) Some comments alerted maintainers to look at various header files to
make matching updates if certain code were to be changed. Updated these
comments to use the new include paths.
3) Some header files mentioned their own names in initial comments. Just
deleted these self references.

Change all ia64 machvecs to use the new dma_*map*_attrs() interfaces.
Implement the old dma_*map_*() interfaces in terms of the corresponding new
interfaces. For ia64/sn, make use of one dma attribute,
DMA_ATTR_WRITE_BARRIER. Introduce swiotlb_*map*_attrs() functions.

include/scsi/scsi_eh.h:79: error: field `sense_sgl' has incomplete type
x86 resolves this by including scatterlist.h from dma-mapping.h which
seems as good a place as any.

On ia64, drivers/base/dma-mapping.c doesn't build because it calls
dma_alloc_noncoherent() and dma_free_noncoherent(), which appear to be
terminally broken; the calls end up generating errors like
drivers/base/dma-mapping.c: In function 'dmam_noncoherent_release':
drivers/base/dma-mapping.c:32: error: 'struct ia64_machine_vector' has no member named 'platform_dma_free_coherent'
because the multiple levels of macro expansion in <asm/dma-mapping.h> and
<asm/machvec.h> end up turning a call to dma_free_noncoherent() into
ia64_mv.platform_dma_free_coherent (instead of the intended
ia64_mv.dma_free_coherent).
This patch fixes this by converting dma_{alloc,free}_noncoherent() into
inline functions that call the corresponding coherent functions, instead of
trying to do this with macros.

Pass struct dev pointer to dma_cache_sync()
dma_cache_sync() is ill-designed in that it does not have a struct device
pointer argument which makes proper support for systems that consist of a
mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync
to take a struct device pointer as first argument and fix all its callers
to pass it.

dma_is_consistent() is ill-designed in that it does not have a struct
device pointer argument which makes proper support for systems that consist
of a mix of coherent and non-coherent DMA devices hard. Change
dma_is_consistent to take a struct device pointer as first argument and fix
the sole caller to pass it.

The current ia64 implementation of dma_get_cache_alignment does not work
for modules because it relies on a symbol which is not exported. Direct
access to a global is a little ugly anyway, so this patch re-implements
dma_get_cache_alignment in a manner similar to what is currently used for
x86_64.

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!
