Subject: [GIT PULL] iommu/arm-smmu: Fixes for 6.9-rc

Hi Joerg,

Please can you pull these two Arm SMMUv3 fixes for an upcoming 6.9 -rc?
One of them fixes a regression on big-endian machines that was
introduced during the recent merge window, whereas the other fixes a
longer standing bug for hardware that doesn't implement attribute
overrides.

Summary in the tag.

Cheers,

Will
