Merge branch 'for-next/iommu/vt-d' into for-next/iommu/core

Browse Source 
Intel VT-D updates for 5.11. The main thing here is converting the code
over to the iommu-dma API, which required some improvements to the core
code to preserve existing functionality.

* for-next/iommu/vt-d:
  iommu/vt-d: Avoid GFP_ATOMIC where it is not needed
  iommu/vt-d: Remove set but not used variable
  iommu/vt-d: Cleanup after converting to dma-iommu ops
  iommu/vt-d: Convert intel iommu driver to the iommu ops
  iommu/vt-d: Update domain geometry in iommu_ops.at(de)tach_dev
  iommu: Add quirk for Intel graphic devices in map_sg
  iommu: Allow the dma-iommu api to use bounce buffers
  iommu: Add iommu_dma_free_cpu_cached_iovas()
  iommu: Handle freelists when using deferred flushing in iommu drivers
  iommu/vt-d: include conditionally on CONFIG_INTEL_IOMMU_SVM
