Giovanni Gherdovich 23ccee22e8 x86, sched: Account for CPUs with less than 4 cores in freq. invariance ... If a CPU has less than 4 physical cores, MSR_TURBO_RATIO_LIMIT will rightfully report that the 4C turbo ratio is zero. In such cases, use the 1C turbo ratio instead for frequency invariance calculations.
