We don't. I wasn't aware that 6fc3a8636a7b exists and had this one in my tree
prior to 6.0.
(well... technically we do need those other symbols and don't need VIRTIO, but
since CONFIG_UML_PCI_OVER_VIRTIO pull in those two, it also works).
Since docs were not updated, I didn't see any conflicts when rebasing.

Sorry for the noise, please ignore this patch.
