Let's just go with printk_once() for right now.  We probably need to have a 
better, more consistent approach to error messages not related to the normal 
access control stuff, however, I'd like to fix this for the v3.18-rcX releases 
and that is a bit out of scope for right now.

Ideally I'd like to fix it this week.  Richard, any chance you can submit a 
patch by the end of the day on Tuesday?  It really should be trivial; if you 
can't let me know and I'll take care of it.
