    arm/arm64: KVM: split GICv2 specific emulation code from vgic.c · 1d916229
    Andre Przywara authored
    vgic.c is currently a mixture of generic vGIC emulation code and
    functions specific to emulating a GICv2. To ease the addition of
    GICv3, split off strictly v2 specific parts into a new file
    vgic-v2-emul.c.
