Hmmm. But that can be misleading, as something like "Cc:
<stable@xxxxxxxxxxxxxxx> # 3.3.x" might only have been used because the
submitter only tested if the change applies and works there while not
bothering with earlier kernels; similar things can happen if 3.2 and
earlier required changes to the patch due to API changes or file
movements the submitter was not willing to handle.

But I don't care. I already integrated a change like outlined earlier in
my local WIP document, but I can quickly remove it again.

Ciao, Thorsten
