Bug description:
  The following patch fixes a problem with "[PATCH] pci-hyperv: Use
  device serial number as PCI domain" where some drivers were expecting
  a u16 instead of a u32 for PCI device serial numbers, as observed by
  Oops and hangs in Azure on NC and NV GPU instances.

  From: Haiyang Zhang <haiyangz@xxxxxxxxxxxxx>

  This patch uses the lower 16 bits of the serial number as PCI
  domain, otherwise some drivers may not be able to handle it.
