271	  secondary PCI host bridge that allows PCI Express root ports,
272	  and devices attached to them, to be removed from the default
273	  PCI domain and placed within the VMD domain. This provides
274	  more bus resources than are otherwise possible with a
275	  single domain. If you know your system provides one of these and
276	  has devices attached to it, say Y; if you are not sure, say N.
277
278	  To compile this driver as a module, choose M here: the
279	  module will be called vmd.
