  Log:
  MFC: Always enable hyperthreading to avoid lockups due to APIC interrupt
  routing problems.
  - Enable cpu_idle_hlt for the SMP case by default since that significantly
    helps HTT performance.
  - Provide a facility for disabling individual CPUs by refusing to schedule
    processes on them.
  - Use the above to provide a sysctl for disabling or enabling all logical
    CPUs.  The default is to disable all logical CPUs.
  - Remove the 'HTT' kernel option now that it is obsolete.
