Shouldn't put_cpu() take a (possibly dummy) `cpu' parameter, as

Please tell me that you're joking.
There is absolutely no reason for it, since there is only one CPU that
you can put (the one you're already on.) The only thing that will
happen if you insist on carrying the CPU number forward (unless it is
used anyway) is that the compiler will generate worse code.
get_cpu() returning the CPU you're on is a convenience; it's so you
don't need to do a third operation just to get your current CPU number,
but it could just as easily be done that way.
