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!
