Yes, https://gitlab.com/cailca/linux-mm/-/blob/master/powerpc.config
We tested here almost daily on linux-next.

All threads of a SMT4 core can either be part of this CPU's l2-cache
mask or not related to this CPU l2-cache mask. Use this relation to
reduce the number of iterations needed to find all the CPUs that share
the same l2-cache.
Use a temporary mask to iterate through the CPUs that may share l2_cach
