During my work on cleaning up the pci dependencies on s390x (see my "s390x: zPCI detangling" patch series), I noticed that the 9pfs code is only built if CONFIG_PCI is set. There's really nothing in there that should depend on CONFIG_PCI (it is really transport-agnostic); we do want to make sure that we have a virtio-9p-transport device, however.
This patch is on top of master; it does not really make a difference right now, but will be needed after my patch series to avoid an inconsistent config for s390x with pci off.
