[PATCH 0/2] sched: arch_scale_smt_powers

The new Power7 processor has 4 way SMT. 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.
