Would you also make sure that Andrew has the necessary bits to keep
Calgary going under PCI domains? If it's a patch that sits on top of
linux-2.6.git + my patch, I can merge it into misc-2.6.git#pciseg (which
automatically goes into -mm). Otherwise, make sure -mm has the stack of
patches necessary.
