SVN rev 191643 on 2009-04-29 03:15:43Z by jeff
- Remove the bogus idle thread state code. This may have a race in it
and it only optimized out an ipi or mwait in very few cases.
- Skip the adaptive idle code when running on SMT or HTT cores. This
just wastes cpu time that could be used on a busy thread on the same
core.
- Rename CG_FLAG_THREAD to CG_FLAG_SMT to be more descriptive. Re-use
CG_FLAG_THREAD to mean SMT or HTT.
