That doesn't work - gcc warns about it.

That turns out to be a problem with %#p too. 

It's really irritating how we cannot extend on the printk strings without 
either having to throw out gcc warnings altogether. gcc has no extension 
mechanism to the built-in rules ;/

The format warnings are too useful to drop entirely. I guess sparse could 
be taught to do them, and then we could drop the gcc support for them. But 
that would still limit coverage a _lot_.
