Yes, I think you should use the early versions when you're, well,
*early* :-) But get rid of that for_each_possible_cpu() and do it only
on the current CPU, as this is a per-CPU path anyway. If you need to
do it on *every* CPU and very early, then you need a separate function
which is called in kvm_smp_prepare_boot_cpu() as there you're pre-SMP.
