Please check my kernel config file:
> cat /usr/src/linux/.config | grep -i cpu
# CONFIG_GENERIC_CPU is not set
# CPU Frequency scaling
# CONFIG_CPU_FREQ_DEBUG is not set
# CONFIG_CPU_FREQ_STAT_DETAILS is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
# CPUFreq processor drivers
# CONFIG_X86_ACPI_CPUFREQ is not set
# CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set
