map_resources is the last initialization step. It is executed on first VCPU run. At that stage the code checks that userspace has provided the base addresses for the relevant VGIC regions, which depend on the type of VGIC that is exposed to the guest. Also we check if the two regions overlap. If the checks succeeded, we register the respective register frames with the kvm_io_bus framework. If we emulate a GICv2, the function also forces vgic_init execution if it has not been executed yet. Also we map the virtual GIC CPU interface onto the guest's CPU interface.
