I've pushed your kernel patch upstream for kernel 3.17.
Furthermore I've scheduled it for backporting into kernels >= 3.13.
I would have liked to go back to kernel 3.0, but then more patches would have needed to be backported.

Maybe someone now can start to push the gcc patch upstream?

Thanks!
Helge
