You have read the file, Documentation/stable_kernel_rules.txt, right?
But please remember, the 3.7 kernel is now end-of-life, as of the 3.7.10
kernel release, so even if this was a bug fix that was applicable to
stable kernels, it would be impossible to get it into the 3.7.y
releases, without going back in time.
