Arnd reports a build warning[1] thanks to me missing ipmmu-vmsa's second set of ops when converting io-pgtable-arm users to the new iommu_iotlb_* callbacks. Rather than just treat the symptom with a point fix, this seemed like a good excuse to clean up the messy #ifdeffery and duplication in the driver that led to the oversight in the first place. Build-tested successfully for arm64, ARM, and ARM + CONFIG_IOMMU_DMA. Robin.
