  Log:
  Adjust the global MSI blacklisting strategy so we don't have to explicitly
  blacklist a bunch of old chipsets.  If a system contains a PCI-PCI bridge
  that supports PCI-X, assume the chipset supports PCI-X.  If a system
  contains a PCI-express root port, assume the chipset supports PCI-express.
  If the chipset doesn't support either PCI-X or PCI-express, then blacklist
  it by default.  We should now only need to explicitly blacklist PCI-X or
  PCI-express chipsets that don't properly handle MSI.
