The module exports data from a new hypervisor call H_BEST_ENERGY. Comments and suggestions made on the previous iteration of the patch has been incorporated. [RFC] powerpc: add support for new hcall H_BEST_ENERGY http://lists.ozlabs.org/pipermail/linuxppc-dev/2010-March/080796.html Changes from v1: * Cleanup cpu/thread/core APIs * Export APIs to module instead of threads_per_core * Use of_find_node_by_path() instead of of_find_node_by_name() * Error checking and whitespace cleanups Please review and let me know your comments. I will post the next version ready for inclusion into powerpc/next tree along with test reports. The current patch series is on 2.6.34-rc6.
