Well, 2.6.34 was released already. I think it's a bit premature. We need
to fix a few more things (the result codes for example) and do more
testing to ensure we didn't break other archs.

Also, Yinghai wants some more changes to the core that I need to discuss
with him to understand exactly what he wants and why :-)

Cheers,
Ben.
