v5 -> v6: Fixed kernel doc. Fixed S-o-B on PATCH 1/7. Added driver power management to save and restoring VMD pci state. Allow VMD domains to be accisble to aer_inject, which requires a minor change to use 32-bit pci domains. Changed child bus resource conflict detection on walking the pci domain. If the bus resource aperture is not large enough, we can enumerate only a sub-tree of the topology. A bridge device with subordinate outside the range should not be allocated. Checking for the conflict after the child is allocated retains pointer to the removed subordinate bus. The way to fix that is to call "pci_remove_bus_device" instead, but I don't think we want to remove the bridge dev since it is accessible, albeit not very useful as a bridge device.
