    Pull IOMMU fixes from Joerg Roedel:
     "These fixes are all for the AMD IOMMU driver:
    
       - A regression with HSA caused by the conversion of the driver to
         default domains.  The fixes make sure that an HSA device can still
         be attached to an IOMMUv2 domain and that these domains also allow
         non-IOMMUv2 capable devices.
    
       - Fix iommu=pt mode which did not work because the dma_ops where set
         to nommu_ops, which breaks devices that can only do 32bit DMA.
    
       - Fix an issue with non-PCI devices not working, because there are no
         dma_ops for them.  This issue was discovered recently as new AMD
         x86 platforms have non-PCI devices too"
