Prompted by the recent mails on ksummit, let's actually try to make this work this time. We need a container for manipulating strings easily, and seq_buf is the closest thing we have to it. The only problem I have with it is the readpos that is only useful for the tracing code today. So move it from the seq_buf to the tracing code.
We should go further with this patch series, including using seq_buf within vsprintf, but if we can't get over this hurdle first, I'm not going to waste my time on this again.
