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.
