Subject: [GIT PULL] IOMMU updates for 5.11
Hi Linus,
Please pull these IOMMU updates for 5.11: there's a good mixture of
improvements to the core code and driver changes across the board.
Summary in the tag and merge commits.
One thing worth pointing out is that this includes a quirk to work
around behaviour in the i915 driver (see 65f746e8285f ("iommu: Add quirk
for Intel graphic devices in map_sg")), which otherwise interacts badly
with the conversion of the intel IOMMU driver over to the DMA-IOMMU APU
but has being fixed properly in the DRM tree. We'll revert the quirk
later this cycle once we've confirmed that things don't fall apart
without it.
Cheers,
Will
