For acpi_cpufreq and cppc_cpufreq, both cpuinfo_cur_freq and
scaling_cur_freq exist. For pstate, only scaling_cur_freq exists.
And value in scaling_cur_freq and cpuinfo_cur_freq may not be the
same. For acpi_cpufreq and cppc_cpufreq, we should check
cpuinfo_cur_freq but not scaling_cur_freq. So her
4 matches
