[PATCHv2 0/2] sched: arch_scale_smt_powers v2

From: Joel Schopp
Date: Tue Jan 26 2010 - 18:28:45 EST

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

Joel Schopp (2):
powerpc: implement arch_scale_smt_power for Power7
sched: enable ARCH_POWER
