On my Juno (2+4 big.LITTLE), sys/kernel/debug/sched/domains/ is now empty. I think that's because of unregister_sched_domain_sysctl() - debugfs_remove() is recursive, and I do get a case where we rebuild the domains but no CPU has been added or removed (we rebuild the domains when cpufreq kicks in, it's part of the big.LITTLE ponies). Do we actually still need that unregister? From a brief glance it looks like we could throw it out.
