Why do you need this reverse lookup? You should only be accessing the per cpu variable for your current cpu (with preemption disabled) in your code. That’s how they are meant to work. In any case, you can simply iterate across all the pointers to find out the cpu# (O(n) time). There does not seem to be any back index pointing to the corresponding cpu# in the structure.
