The IOMMU code has been passing the dma-mask instead of the coherent_dma_mask to the iommu allocator. Coherent allocations should be made using the coherent_dma_mask. Also update the vio code to ensure the coherent_dma_mask is set. Without this change drivers, such as ibmvscsi, fail to load with the corrected dma_iommu_alloc_coherent(). Signed-off-by:
