[PATCH v2 0/1] Put seq_buf on a diet

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.

v2:
- Add linux-trace-kernel@xxxxxxxxxxxxxxx
- Fix kernel-doc
