Ok, my HP lappy running master.today still defaults to powersave, with CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL=3Dy, still disallows selecting ondemand as before, and powersave still works. IOW for lappy, it was business as usual, no change. Desktop box did, it gained a working ondemand, while its previously working powersave went broke. Box had schedutil forced upon it, but it seems perfectly fine with that performance wise. -Mike
