really?  no way.  get outta town.

  sorry, but there was no way i could resist that.  :-)  *of course* i
realize that.  *all* of those things (__setup, early_param, actual
module params) are potential entries on the kernel line at boot time,
depending on your particular configuration.

  all i'm suggesting is that there is an obvious distinction between
those that are defined using __setup() or early_param(), and those
that are actual module parameters.  and that it would make more sense
to keep them separate, even if only separating them within the same
text file.

  in the end, there should be a nice, *short* reference for what i
like to call "basic" kernel parms (defined by __setup() or
early_param()), while anyone who wants to learn about any
module-specific parms should then have to go look up the info for that
given module, that's all.

  as a trivial starting point, this would involve nothing more than
shifting current content around in kernel-parameters.txt, putting the
basic stuff at the top, and the module-specific stuff after that.
heck, that would even give module authors the chance to add a line or
two of module description if they wanted.  how does life get any
better than that?
