     "Trimmed second batch of KVM changes for Linux 4.15:
    
       - GICv4 Support for KVM/ARM
    
       - re-introduce support for CPUs without virtual NMI (cc stable) and
         allow testing of KVM without virtual NMI on available CPUs
    
       - fix long-standing performance issues with assigned devices on AMD
         (cc stable)"
