This is already in the patch tracker

I also notice that store_cpu_topology() should be marked __cpuinit and
update_siblings_mask, middle_capacity, cpu_capacity, and
update_cpu_power should be static. We should probably also rename
update_cpu_power() so as to not conflict with the one in kernel/sched/fair.c
