Hi Joerg, My PAMU driver patches depend on this patch which was Ack by Kumar. Should I resubmit this patch as well?

[PATCH 2/5 v11] powerpc: Add iommu domain pointer to device archdata
Add an iommu domain pointer to device (powerpc) archdata. Devices
are attached to iommu domains and this pointer provides a mechanism
to correlate between a device and the associated iommu domain. This
field is set when a device is attached to a domain.
