If this series are going to be split for easier review, this is an candidate

I don't see why virt_find_cpu_slot() is needed. Apart from the sanity check, it
basically returns ms->possible_cpus->cpus[]. The caller can dereference
ms->possible_cpus->cpus[] directly. About the sanity check, the mp_affinity
has been properly populated in virt_possible_cpu_arch_ids(). I don't see why
we it needs to be checked again.
