v1: https://lore.kernel.org/linux-iommu/cover.1626888444.git.robin.murphy@xxxxxxx/
v2: https://lore.kernel.org/linux-iommu/cover.1627468308.git.robin.murphy@xxxxxxx/
v3: https://lore.kernel.org/linux-iommu/cover.1628094600.git.robin.murphy@xxxxxxx/

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.
