The changes also remove the field entirely from the architectures which no longer need it. On PowerPC the field is called dev->archdata.iommu_domain and was only used by the PAMU IOMMU driver. It gets removed as well. The patches have been runtime tested on Intel VT-d and compile tested with allyesconfig for: * x86 (32 and 64 bit) * arm and arm64 * ia64 (only drivers/ because build failed for me in arch/ia64) * PPC64 Besides that the changes also survived my IOMMU tree compile tests. Please review.
