There's nothing I can say in my defense, Linus has made that very clear,
over and again.

When I realized the alignment mistake there were already shipping
binaries so I decided it was too late to change that.

And I see I got the analysis of the architectures alignment wrong, mmmm,
that's bad as well.

I guess I'll just be quiet now since anything I say is probably going to
be wrong.
