Not always.
When there is usual kernel config - at kernel update there's usual tens or even hundreds new options that should be choosed. And using .cdiff with generic kernel you should only enable new platform-specific drivers; generic options like network stack are applied automatically. > >> For me, migration to new kernel (when I experimented with different >> versions due to crashes with PPPoE on 4.1) takes max 10-15 minutes - >> even when I switched from 4.1 to old 3.2. > Which I consider very long for just a kernel upgrade. Not too long - it's done just once (ok, maybe - twice as in 5.2 case, when we switched from 5.1's 3.10 to 3.14 and then to 4.1) per minor release. > And you still have > to generate the full config for every arch.

It seems like you re-generated kernel config from scratch. With a lot of completely unneeded stuff. I just applied your changes in your old branch to new kernel configs. They lays perfectly. ------------------------------------------------------------------------------ Transform Data into Opportunity.
