Here is a crude attempt fix race the way suggested by Greg, probably done wrong but hopefully in the right direction.
1. move "crash_notes" to static attributes to guarantee that it's destroyed with CPU on unregister.
2. fixes race between hotplugged CPU and onlining it via udev, described here https://lkml.org/lkml/2012/4/30/193
