Since commit d6f346f2d2 (cpuidle: improve governor Kconfig options)
the best cpuidle governor is selected automatically. There is little
point in additionally selecting the other one as it will not be used,
so don't select both governors by default.
Being able to select more than one governor is still good for
developers booting with cpuidle_sysfs_switch, though.
This fixes the second half of kernel BZ #65531.

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.
