I still don't see the logic there for *wanting* kdump to be wrong.

Sure, kdump getting it right doesn't necessarily make a big difference
in itself.

But given that the error has been pointed out, what is the motivation
for *wanting* the error to remain in the kdump code, instead of just
fixing it? "Consistency" isn't an answer because we are *already*
inconsistent — some code gets it right, and other code doesn't.

We should converge towards *correctness* rather than deliberately
adding more incorrect code.

I've used my 'i' key more times just in typing this email than it would
have taken to just fix the problem the first time it was pointed out.

Coming up. In two parts — user-visible messages, followed by cosmetic
and less relevant stuff.
