Actually, let's just drop the log_lvl printout in the middle.

And to do that, let's clean up printk() a bit further - just make it say 
"if there is no loglevel, use the previous loglevel". That's going to 
simplify _all_ kinds of multi-line code.

As far as I can tell, that's a oneliner: make 'current_log_level' be a 
'static' variable.

Wouldn't that be much simpler for everybody?

(And yes, if you mix multi-line messages that are printed as separate 
printk's and with different loglevels, output will be confused. But quite 
frankly, it will be confused regardless)
