Swapped the order of PATCH1 and PATCH2 in V1 so as to not mess with the nr_busy_cpus parameter computation during asymmetric balancing, while fixing it. 2. nohz_busy_cpus parameter is to be updated and queried at only one level of the sched domain-sd_busy where it is relevant. 3. Introduce sd_asym to represent the sched domain where asymmetric load balancing has to be done. --- Preeti U Murthy (1): sched: Remove un-necessary iteration over sched domains to update nr_busy_cpus Vaidyanathan Srinivasan (1): sched: Fix asymmetric scheduling for POWER7 kernel/sched/core.c | 6 ++++++ kernel/sched/fair.c | 38 ++++++++++++++++++++------------------ kernel/sched/sched.h | 2 ++ 3 files changed, 28 insertions(+), 18 deletions(-)
