Ok, it is rebased on top of linux-next, however the conflict is coming
from the energy model patchset sent by Quentin [1][2] I used to based my
series which is not yet applied in the thermal tree.

I'm wondering if it wouldn't make sense to take Quentin's series also,
it is a long time around in the mailing list, reviewed and acked. So I
can send the two remaining patches on top of it without conflict,
otherwise we will have a conflict in the merge window.
