- Include upstream patches designated as stable material and
  reviewed for applicability to include here. NOTE that the
  PIIX4 patch has migration implications: the change will also be
  applied to the SLE-15-SP2 qemu, and a live migration from that
  version to this SLE-15-SP3 qemu would require this patch to be
  applied for a successful migration if PIIX4 southbridge is used
  in the machine emulation (x86 i440fx)
