Subject[PATCH 1/1] x86 idle: APM requires pm_idle/default_idle unconditionally when a module
Date
The commit below removed the export for pm_idle/default_idle unless the
apm module was modularised and CONFIG_APM_CPU_IDLE was set. The apm
module uses pm_idle/default_idle unconditionally, CONFIG_APM_CPU_IDLE
only affects the bios idle threshold. Adjust the export accordingly.
