The fixes include:
* Two patches to revert the use of default domains in the ARM
SMMU driver. Enabling this caused regressions which need more
thorough fixing. So the regressions are fixed for now by
disabling the use of default domains.
* A fix for a v4.4 regression in the AMD IOMMU driver which
broke devices behind invisible PCIe-to-PCI bridges with IOMMU
enabled.
