My local workflow is normally that I update my trees, then run a "make oldconfig" and go with the defaults on new options. When I do that, the layerscape arch option drops off, which turned out to be unfortunate since it was the machine I was running on. It's less of an issue if you use an in-tree defconfig (presuming they get updated). I worry that distros will have similar issues if they supply their own config. Again, this is a one-time thing but it's easier for everybody if we find ways to avoid them. Giving these new groups a "default y" might not help either, since that would need to come off at some point, and at that time the same issue will arise. -Olof _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
