Yes, sorry, I should have said incorporated/pushed back

If you consider, for the moment, not pushing the patches in 3.4, 
(because of stability concerns, or you judge these patches intrusives, 
or whatever good reason), I won't do either, because I have no vision of 
the potential problems with the patched kernel. I always try to stay on 
pure vanilla kernels, longterm if possible, because stability is the 
more important.

My best bet is probably 3.8 kernels right now (even if they are not 
longterm), or maybe simply going back to 3.2.

Thanks for your answers,
Cheers
