This is already in the patch tracker
http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7482/1
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
