Linux 3.4 rc7

This is almost certainly the last -rc in this series - things really
have calmed down, and I even considered just cutting 3.4 this weekend,
but felt that another week wouldn't hurt.

The appended shortlog gives a good overview - it's mostly random tiny
fixes for very small specific issues. The biggest commit (and the one
that might affect the most people) is likely the Nouveau i2c change,
and that one is really just a revert. It changes nouveau back to use
the generic i2c-algo-bit routines - the problem they had had been
fixed in the meantime, and the specialized i2c nouveau routines had
issues of their own.
