Hi! Yes, the defconfig is not yet very Android specific. Alexandre is currently working on unifying it. Maybe we can benefit from his work. Otherwise I'll have a closer look into our defconfig after my vacation. /dev/cpuctl is available in the 3.12-replicant4 kernel. I think in the 3.12-master defconfig Cgroups aren't enabled at all.
