    arm/arm64: KVM: add virtual GICv3 distributor emulation · a0675c25
    Andre Przywara authored
    With everything separated and prepared, we implement a model of a
    GICv3 distributor and redistributors by using the existing framework
    to provide handler functions for each register group.
    
    Currently we limit the emulation to a model enforcing a single
    security state, with SRE==1 (forcing system register access) and
    ARE==1 (allowing more than 8 VCPUs).
    
    We share some of the functions provided for GICv2 emulation, but take
    the different ways of addressing (v)CPUs into account.
    Save and restore is currently not implemented.
    
    Similar to the split-off of the GICv2 specific code, the new emulation
    code goes into a new file (vgic-v3-emul.c).
