This 4 way SMT benefits from dynamic power updates that arch_scale_smt_power was designed to provide. The first patch fixes a generic scheduler bug necessary for arch_scale_smt to properly function. The second patch implements arch_scale_smt_power for powerpc, and in particular for Power7 processors. --- Gautham R Shenoy (1): sched: Fix the place where group powers are updated.
