At the moment the KVM VGICv3 only supports a single redistributor region (whose base address is set through the GICv3 kvm device KVM_DEV_ARM_VGIC_GRP_ADDR/KVM_VGIC_V3_ADDR_TYPE_REDIST). There, all the redistributors are laid out contiguously. The size of this single redistributor region is not set

[PATCH v3 03/12] KVM: arm/arm64: Replace the single rdist region by a list

At the moment KVM supports a single rdist region. We want to support several separate rdist regions so let's introduce a list of them. This patch currently only cares about a single entry in this list as the functionality to register several redist regions is not yet there. So this only translates
