260	  Adds support for the Intel Volume Management Device (VMD). VMD is a
261	  secondary PCI host bridge that allows PCI Express root ports,
262	  and devices attached to them, to be removed from the default
263	  PCI domain and placed within the VMD domain. This provides
264	  more bus resources than are otherwise possible with a
265	  single domain. If you know your system provides one of these and
266	  has devices attached to it, say Y; if you are not sure, say N.
267
268	  To compile this driver as a module, choose M here: the
269	  module will be called vmd.
