Hmm, this is an interesting one, because I think we still generally just want 
to refer to the API as being `printk()`. Changing it all over the place seems 
wrong. As you'd imagine, there are quite a few references to this name, so it 
requires a lot of noise all over the docs and inline comments.

Jonathan and other docs folks, how can one tell Sphinx that when it sees 
printk() it's referring to a function-like macro, or otherwise squelch this 
reasonably? :-)
