Yes. And another one has by Rb already I believe. I hope Alex can start
cherry-picking some more patches when he gets back to NUE.

I know you had some open questions I still need to reply to. Among
others, yes, I concur with mst that ppc/spapr_pci.c could be moved to
pci-host/spapr.c, but remember to update MAINTAINERS for you guys to
still get CC'ed on it then.

I had asked Anthony to reply to the KVM XICS patch because he said that
accessing the parent's method seemed wrong to him and the parent
implement should be put in charge of calling rather than the derived.
I.e., I will be dropping my proposed OBJECT_GET_PARENT_CLASS() macro and
started redoing several series. Haven't looked into how exactly your
code (CPU setup I think?) may need to change.
