Why is it an initcall? So far, the only initcall we've used is the one
that initializes KVM itself. Can't we just the device_ops just like we
do for the vgic?

So would you prefer a direct call from init_subsystems() in
virt/kvm/arm/arm.c?

The benefit of initcall is just that it keeps the code self-contained.
In init_subsystems() I'd either need a #ifdef CONFIG_ARM64 or a dummy
function for arm.
