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.
I'm trying to test this on an old Sandy Bridge, but found that I get
spammed with warnings on boot. I've put a sample of a few of them below.
They all seem to be related to ioat.
I had the same issue with Tom's v2 but never saw this on his v1.
