    Fire up the kernel editor and search for the strings. It's not hard.
    Code:
    CONFIG_CPU_IDLE:
    
    CPU idle is a generic framework for supporting software-controlled
    idle processor power management. It includes modular cross-platform
    governors that can be swapped during runtime.
    
    If you're using an ACPI-enabled platform, you should say Y here.
    
    Symbol: CPU_IDLE [=y]
    Type : boolean
    Prompt: CPU idle PM support
    Defined at drivers/cpuidle/Kconfig:2
    Location:
    -> Power management and ACPI options
    Selected by: ACPI_PROCESSOR [=y] && ACPI [=y]
