Since it looks like vCPU hot-add will be implemented differently, I don't
intend to resend this series at the moment. But some of it could be
useful for other projects and to avoid the helpful review effort going to
waste, I fixed it up and will leave it on branch
https://jpbrucker.net/git/linux/log/?h=kvm/psci-to-userspace
It now only uses KVM_CAP_EXIT_HYPERCALL introduced in v5.14.

Thanks,
Jean
