I wonder if really want a mask or a max_zone_dma_address like variable. So for this series feel free to drop the patch. I'll see if I'll pick it up later or if we can find some way to automatically propagate that information from the zone initialization. _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
