Hi Daniel,
This hotplug noifiers looks fine. I suppose it should add extra state
C1 in cpu0. If it is done like below than for normal cases(when all
cpu's are online) there wont be any statistics for C0 state also which
is required. Other patches look good.
Thanks,

Instead of making all the trip-points of a thermal zone writeable we should
