I should mention that this is triggered a lot by our platform using
several disparate mem=n arguments on the command line,
chopping out pieces of memory here and there.

I will repost with a more descriptive message and then I'll
put it into the patch tracker, as it's a blocker already on 3.0
for us.

Yours,
Linus Walleij
