The vgic code on ARM is built for all configurations that enable KVM, but the parent_data field that it references is only present when CONFIG_IRQ_DOMAIN_HIERARCHY is set: virt/kvm/arm/vgic.c: In function 'kvm_vgic_map_phys_irq': virt/kvm/arm/vgic.c:1781:13: error: 'struct irq_data' has no member named 'parent_data' This flag is implied by the GIC driver, and indeed the VGIC code only makes sense if a GIC is present. This changes the CONFIG_KVM symbol to always select GIC, which avoids the issue.
