I saw responses from Keith and Bryan, and I hope they answer your
questions. As far as I can tell, the VMD driver is grossly similar to
other host bridge drivers we've already merged, and I don't think we
have public specs for all of them.

Unless you have further concerns, I'm going to ask Linus to pull this
tomorrow, along with the rest of the PCI changes for v4.5.
