This set of patches implemets PCI support for the s390 platform. Now it is possible to run virtio-net-pci and potentially all virtual pci devices conforming to s390 platform constrains. (In parallel I also post some changes to make vfio run on s390)
I hope to get feedback and guidance especially for kvm: extend kvm_irqchip_add_msi_route to work on s390 which adds the s390 interpretation of MSI-X to the common kvm add_msi_route functionality.
