We can get rid of the "power5+" / "power7+" hack in qom/object.c by using CPU aliases for those names instead (first patch). I think in the long run, we should get rid of the names with a "+" in it completely, so the second patch suggests to deprecate those, but I'd also be fine if we keep the aliases around, so in that case please ignore the second patch.
