    powerpc/kvm: Native usage of the XIVE interrupt controller
    
    This patch makes KVM capable of using the XIVE interrupt controller
    to provide the standard PAPR "XICS" style hypercalls. It is necessary
    for proper operations when the host uses XIVE natively.
    
    This has been lightly tested on an actual system, including PCI
    pass-through with a TG3 device.

    [mpe: Cleanup pr_xxx(), unsplit pr_xxx() strings, etc., fix build
     failures by adding KVM_XIVE which depends on KVM_XICS and XIVE, and
     adding empty stubs for the kvm_xive_xxx() routines]
