Currently, the only architectures that don't set HAS_DMA are h8300, m32r m68k (except SUN3 and Coldfire), microblaze and s390. s390 will never get it, microblaze is currently implementing dma-mapping.h. The other three are still using drivers/ide instead of drivers/ata. One way to fix this would be to implement dma-mapping.h in h8300, m32r and m68k and leave !HAS_DMA as the obscure s390 case (this one already can't use ATA because of !HAS_MMIO).
If I'm reading the m68k code correctly, SUN3 is the one that doesn't have DMA. It is implemented on any m68k with a standard Motorola MMU. It might be possible to get the DMA code working on a sun3, but I doubt they ever have IDE hardware.
