Changes since v3:

 * Leave the --super-prefix changes aside for now. As discussed in the
   v3 follow-up, now we're only removing the unused $prefix variable.

   Since the v2 was submitted Glen's submitted a series of his own. I
   think any non-trivial updates to --super-prefix are better done
   there, as noted in:
   https://lore.kernel.org/git/220628.86wnd1f9t1.gmgdl@evledraar.gmail.com/ (local)

   The overall diffstat is much smaller as a result, and I think this
   series should be ready for "next" now, as the remaining changes are
   well-revieweda at this point, with no outstanding issues.

Agreed. Since we no longer touch "--super-prefix", I think there aren't
any remaining concerns.

In v3, I was slightly concerned that we didn't fully understand the
rationale behind "--super-prefix" before changing it, but I still gave
that version my Reviewed-by because I'm convinced that the
"--super-prefix" check isn't doing anything useful (and can be
annoyingly overzealous).
