No need to have 'oc == NULL' since object_class_dynamic_cast()
covers it. Besides, we don't expect an abstrat CPU class returned
from CPUClass::cpu_class_by_name() in the middle on alpha and rx.

This appears to be a rebase error, re-introducing code removed in patch 3.
I think the entire patch should be dropped.
