- Reorder MINIMAL so everything is in the same order as in GENERIC.
- Wherever comments diverged, except for the explanatory comment at the top, copy the GENERIC version to MINIMAL.
- Add KDTRACE_FRAME to i386 GENERIC; it was already in MINIMAL, and adding it to GENERIC seemed like the more correct move.
With these changes, MINIMAL is a strict subset of GENERIC, apart from
the identifier and the explanatory comment at the top.
