f93e97eaea sh: declared coherent memory support V2
This patch adds declared coherent memory support to the sh architecture. All
functions are based on the x86 implementation. Header files are adjusted to
use the new functions instead of the former consistent_alloc() code.

This version includes the few changes what were included in the fix patch
together with modifications based on feedback from Paul.

322392646b sh: Add missing dma_sync_single_range_for_*().
The b44 build uses these, caught by allmodconfig:

drivers/net/b44.c: In function `b44_sync_dma_desc_for_cpu':
drivers/net/b44.c:159: error: implicit declaration of function `dma_sync_single_range_for_cpu'

Follow the sparc64 change and stub them in.

e257ad062a sh: Kill off virt_to_bus()/bus_to_virt().
Wire up ARCH_NO_VIRT_TO_BUS, and kill off the remaining users. The
dma-mapping code really wanted virt_to_phys()/phys_to_virt() anyways,
there are no inherently special bus addresses.

sh was missing these, too.

d3fa72e455 [PATCH] Pass struct dev pointer to dma_cache_sync()
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.

0d831770b1 [PATCH] sh: DMA updates
This extends the current SH DMA API somewhat to support a proper virtual
channel abstraction, and also works to represent this through the driver model
by giving each DMAC its own platform device.

There's also a few other minor changes to support a few new CPU subtypes, and
make TEI generation for the SH DMAC configurable.

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!
