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.

Version 2 changes:
- Drop Patch 1 from the original series since it's in the -tip tree now
- Move enabling the cpu feature into it's own patch (now patch 1)
- Add stubbing out broken x86 implementation to patch 1
- clean up coding style in patch 2

Version 3 changes:
- Added a comment to Patch 2
