263	  Adds support for the Intel Volume Management Device (VMD). VMD is a
264	  secondary PCI host bridge that allows PCI Express root ports,
265	  and devices attached to them, to be removed from the default
266	  PCI domain and placed within the VMD domain. This provides
267	  more bus resources than are otherwise possible with a
268	  single domain. If you know your system provides one of these and
269	  has devices attached to it, say Y; if you are not sure, say N.
270
271	  To compile this driver as a module, choose M here: the
272	  module will be called vmd.
