So for now I'm assuming that the original patch was written by Mathieu,
with modifications by you. So I added his From line and extended the SOB
chain with the additional information that you modified the patch:

Tested-by: Dietmar Eggemann <dietmar.eggemann@xxxxxxx>
Signed-off-by: Mathieu Poirier <mathieu.poirier@xxxxxxxxxx>
Signed-off-by: Juri Lelli <juri.lelli@xxxxxxxxxx>
[ Various additional modifications. ]
Signed-off-by: Peter Zijlstra (Intel) <peterz@xxxxxxxxxxxxx>
Signed-off-by: Ingo Molnar <mingo@xxxxxxxxxx>

Let me know if that's not accurate!

Thanks,

Ingo
