Convert the intel iommu driver to the dma-ops api so that we can remove a bunch of repeated code.
This patchset depends on the "iommu/vt-d: Delegate DMA domain to generic iommu" and
"iommu/amd: Convert the AMD iommu driver to the dma-iommu api" patch sets which haven't
yet merged so this is just a RFC to get some feedback before I do more testing.
Tom Murphy (7):
iommu/vt-d: Set the dma_ops per device so we can remove the
iommu_no_mapping code
iommu/vt-d: Remove iova handling code from non-dma ops path
iommu: improve iommu iotlb flushing
iommu/dma-iommu: Handle freelists in the dma-iommu api path
iommu/dma-iommu: add wrapper for iommu_dma_free_cpu_cached_iovas
iommu/vt-d: convert the intel iommu driver to the dma-iommu ops api
iommu/vt-d: Always set DMA_PTE_READ if the iommu doens't support zero
