We've been moving to a model where the device just sets the DMA mask supported by it, instead of having to fallback to something it thinks the platform might support. Sparc64 is the remaining holdout forcing drivers to supply a matching mask. Change dma_4u_supported to just check if the supplied dma mask is large enough as nothing in the iommu.c code (or the core DMA code) actually looks at the DMA mask later on.
