@adrian Could you give this patch set a thorough test as well? It is not dependent on D54745, I mainly want some additional testing without this on top of D54745 and a merge before going to the next phase of IOMMU enablement. D54745 has some issues with DMA and the AHCI controller that I don't currently understand and will need further investigation.
