Curious thing happens here. I created the tree as you suggested (branch tip/cpus4096-v2)
and copied in your .config file. Running it through "silentoldconfig" (choosing only
the defaults), I get the following changes. This makes me suspect that I'm not testing
the same thing as you are...? Perhaps my git setup was not correct?
