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). The other way would be to add some #ifdef CONFIG_HAS_DMA in libata-core.c and sas_ata.c.
