Subject: [PATCH v6 0/5] 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:
V6:
-add more details to the description of patch 001-iommu-amd-Remove-unnecessary-locking-from-AMD-iommu-.patch
-rename handle_deferred_device to iommu_dma_deferred_attach
-fix double tabs in 0003-iommu-dma-iommu-Handle-deferred-devices.patch
V5:
-Rebase on top of linux-next
V4:
-Rebase on top of linux-next
-Split the removing of the unnecessary locking in the amd iommu driver into a seperate patch
-refactor the "iommu/dma-iommu: Handle deferred devices" patch and address comments
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 (5):
  iommu/amd: Remove unnecessary locking from AMD iommu driver
  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 AMD iommu driver to the dma-iommu api
