    perfbias: Implement Intel performance-energy hint support
    
    This hint is set on per-logical CPU.  0 delivers highest performance;
    15 maximizes energy saving.  It could be set through sysctl nodes
    machdep.perfbiasX (X is the CPU id).
    
    It is linked into i386 and x86_64 GENERIC kernel.
    
    * We may want to make powerd(8) to aware of these sysctls.
