This series enables the association of IO channels at the CPU-core level (i.e., with all CPUs/threads of core), which may increase performance depending on the CPU affinity settings of the workload (e.g., benefit from the per-core caches); and adds the required pieces to use it on PowerPC64 too (topology information), which has server processors with many cores/threads and per-core caches.
Although the series include bits for PowerPC64, the per-core scheduling patch is architecture independent. Tested on next-20160601 (with an extra commit for patch 1/2, see commit msg).
