I added asm-xxx/dma.h to each archs and moved
MAX_DMADOM_PFN definition to these files.
But I left the value as it was.
(I only did compile tests for x86_32 and ia64.)

Is this patch acceptable or should I refine more?

I don't want Linux-style dma.h in Xen, since Xen really knows nothingabout DMA. :-)

I think MAX_DMADOM_PFN has a limited life ahead of it (I'd like to pushaddress-width awareness into the core of the allocator at some point).So I'll just move MAX_DMADOM_PFN to asm/config.h, then you ia64 guyscan change it as you wish.
