Cover letter [PATCH v4 00/24] iommu: Refactor DMA domain strictness

v1: https://lore.kernel.org/linux-iommu/[email protected]/
v2: https://lore.kernel.org/linux-iommu/[email protected]/
v3: https://lore.kernel.org/linux-iommu/[email protected]/

Hi all,

I'm hoping this is good to go now. Changes from v3 are minimal, just rolling back patch #2 to the non-broken version, and tidying up the final patch as documented there.

Cheers,
Robin.
