Strike that, my cscope setup was messed up.

What I think you want is a static vgic_v3_create in vgic-v3-emul.c that
digs out the struct kvm pointer from the struct kvm_device and calls
kvm_vgic_create() and also just copy that single kfree(dev) line into
vgic_v3_destroy in vgic-v3-emul.c and the same for v2.
