Other things that come to my mind:
- move handling of nowayout into the core
- some drivers use a reboot notifier. Not sure what they are intended
to do there. For i.MX2x it triggers a reboot; for gpio-wdt it tries
to stop the watchdog.

Of course this doesn't mean this should addressed here. I like the
series in general.

Best regards
Uwe
