Sorry, I did a quick grep on MODULE_PARAM and found none, and didn't
realize the pervasiveness of the change.  A more thorough search has
revealed one other.

As such code won't compile as a module, it means we're only going to find
things in code which has these declarations and is only ever built-in.

I've updated my series, and patch FYI below.

Thanks,
Rusty.

You always needed them when you were a module, but the builtin versions
of the macros used to be more lenient.
