  genirq/msi: Store the IOMMU IOVA directly in msi_desc instead of
    iommu_cookie
  genirq/msi: Refactor iommu_dma_compose_msi_msg()

  irqchip: Have CONFIG_IRQ_MSI_IOMMU be selected by irqchips that need
    it
  iommufd: Implement sw_msi support natively

  iommu: Turn fault_data to iommufd private pointer
I dropped this patch:
  iommu: Turn iova_cookie to dma-iommu private pointer
And fixed up the two compilation issues found by building on my x86
config, plus Thomas's language update.

It is headed toward linux-next, give it till monday for a PR to Joerg
just incase there are more randconfig issues.

Thanks,
Jason
