Hi Joerg,

Please pull these Arm SMMU updates for 6.13.

The summary is in the tag, but the highlight is definitely the removal
of the complicated block-splitting code from the Arm page-table
implementations. It even means that we have a negative diffstat!

As with 6.12, I've already pushed this lot to the arm/smmu branch in
the iommu tree. Please can you merge that into 'next'?

Cheers,

Will
