Make sure VMD assigns proper IRQ domain to the child devices during
device enumeration. DMAR errors were observed when interrupt remapping
is enabled by intel_iommu because of the fact that VMD child devices
are on different IRQ domain than all other PCI devices.

Nirmal Patel (2):
  PCI: vmd: Assign VMD IRQ domain before enumeration
  PCI: vmd: Revert 2565e5b69c44 ("PCI: vmd: Do not disable MSI-X
    remapping if interrupt remapping is enabled by IOMMU.")
