[PATCH 1/2] Add new flush_iotlb_range and handle freelists when using iommu_unmap_fast
Add a flush_iotlb_range to allow flushing of an iova range instead of a
full flush in the dma-iommu path.
Allow the iommu_unmap_fast to return newly freed page table pages and
pass the freelist to queue_iova in the dma-iommu ops path.
This patch is useful for iommu drivers (in this case the intel iommu
driver) which ne...

[PATCH 0/8] Convert the intel iommu driver to the dma-iommu api
This patchset converts the intel iommu driver to the dma-iommu api.
While converting the driver I exposed a bug in the intel i915 driver which causes a huge amount of artifacts on the screen of my laptop. You can see a picture of it here:
