  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.
