Well, how should we make it available if dom0 doesn't really allow us to
enumerate PCI roots and thus count AMD nodes?

Andy, see upthread.

What would you suggest we do here on dom0? We're trying to enumerate AMD
nodes but dom0 is doing something special wrt topology and PCI roots - see
get_next_root() in amd_node.c.

Thx.
