[PATCH v4 00/12] KVM: arm/arm64: Allow multiple GICv3 redistributor regions

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 v4 08/12] KVM: arm/arm64: Check vcpu redist base before registering an iodev

As we are going to register several redist regions, vgic_register_all_redist_iodevs() may be called several times. We need to register a redist_iodev for a given vcpu only once. So let's check if the base address has already been set. Initialize this latter in kvm_vgic_vcpu_early_init(). Signed-of
