Don't worry about it for this patchset, it's just something I noticed
when reviewing. I'm wondering why the cpu add algorithm doesn't work
more like the one for memory, which actually queries the platform for
connector status via dlpar_acquire_drc(). It's possible I'm
misunderstanding something though. Like I said, I think it's something
to address separately if there is indeed an issue.
