Nothing - this is just a notification that the test result comparison
is not being compared between a base kernel vs base kernel plus your
changes applied, but rather a base kernel A vs base kernel B plus your
changes.

Ideally, any changes in the comparison are a direct consequence of your
changes, so that it's easy to list all the regressions/fixes in the
test suite, but in this scenario the CI system was unable to find a
tested base, and so just tried to show something useful instead of no
comparison at all.

I've tried to reword this message a few times, but it's still too
confusing... Looks like we need to document this with a few explicit
examples and link them in this message.
