The core problem is this: I want two lines of output: one for the
order/mode gunk, and one for the user-specified message.
If we have the user pass in a string for the printk() level, we're stuck
doing what I have here. If we have them _prepend_ it to the "fmt"
string, then it's harder to figure out below. I guess we could fish in
the string for it.

It's a relic of an hour ago when I tried passing in the printk() level
to the function as a string. It can go away now. :)
