Subject: [PATCH v3 0/4] iommu/amd: Convert the AMD iommu driver to the dma-iommu api

Convert the AMD iommu driver to the dma-iommu api. Remove the iova
handling and reserve region code from the AMD iommu driver.

Change-log:
v3:
-rename dma_limit to dma_mask
-exit handle_deferred_device early if (!is_kdump_kernel())
-remove pointless calls to handle_deferred_device
v2:
-Rebase on top of this series:
 http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/dma-iommu-ops.3
-Add a gfp_t parameter to the iommu_ops::map function.
-Made use of the reserve region code inside the dma-iommu api

Tom Murphy (4):
  iommu: Add gfp parameter to iommu_ops::map
  iommu/dma-iommu: Handle deferred devices
  iommu/dma-iommu: Use the dev->coherent_dma_mask
  iommu/amd: Convert the AMD iommu driver to the dma-iommu api
