Again, stop it with the "generic" hotplug term here, and everywhere
else. You are doing a very _specific_ type of hotplug devices, so spell
it out. We've worked hard to hotplug _everything_ in Linux, you are
going to confuse a lot of people with this type of terms.

What is this? Why not point to the system device for the cpu?

Same here, why not point to the system device?

What happened here with these? Empty structures? Huh?

No, make it a "real" device, embed the device into it.
But, again, I'm going to ask why you aren't using the existing cpu /
memory / bridge / node devices that we have in the kernel. Please use
them, or give me a _really_ good reason why they will not work.

What is this?
