APM emulation: Notify about all suspend events, not just APM invoked ones (v2)

Browse source

This revamps the apm-emulation code to get suspend notifications
regardless of what way pm_suspend() was invoked, whether via the
apm ioctl or via /sys/power/state. Also do some code cleanup and
add comments while at it.
