    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]
