I don't see changelogs inside the individual patches. Please make sure 
to always mention what changed from one version to the next in a 
particular patch, so that I have the chance to check whether that change 
was good :).

Also, is there any performance penalty associated with split core mode? 
If not, could we just always default to split-by-4 on POWER8 bare metal?
