KVM: s390: pci: Hook to access KVM lowlevel from VFIO We have a cross dependency between KVM and VFIO when using s390 vfio_pci_zdev extensions for PCI passthrough To be able to keep both subsystem modular we add a registering hook inside the S390 core code. This fixes a build problem when VFIO is built-in and KVM is built as a module.
