[Intel-gfx] [PATCH v3 0/6] Convert the intel iommu driver to the dma-iommu api

[Lu Baolu]

Tom Murphy has almost done all the work. His latest patch series was
posted here.

https://lore.kernel.org/linux-iommu/20200903201839.7327-1-murphyt7@tcd.ie/

Thanks a lot!

This series is a follow-up with below changes:

1. Add a quirk for the i915 driver issue described in Tom's cover
letter.
2. Fix several bugs in patch "iommu: Allow the dma-iommu api to use
bounce buffers" to make the bounce buffer work for untrusted devices.
3. Several cleanups in iommu/vt-d driver after the conversion.

Please review and test.

Best regards,
baolu
