I think it is -stable material, and I've now applied the three patches
that went into Linus's tree into the 3.4-stable and 3.7-stable trees.
There was only one minor patch problem with 3.4 (comment block not being
needed), if there is more work than that that you think is needed to get
these working in those kernel releases, please let me know.

thanks,
