No more MI diamond and all devices have DeviceStates.
Coincidentally, it matches more closely how hardware works..
Well, I agree, but I honestly lost the context. How does this relate
to the APIC and cpu hotplug?
I'll take the opportunity to say that we should be using a language
that has first-class (...) support for these concepts instead of
having to divine them from the code.
At the risk of sounding uncool, I think what we really need is a UML
diagram describing the device tree. It's really not that much more
difficult to create a similar mess in C++.
That's fine near a whiteboard with some airspace for handwaving.
Doesn't work well through patches and email.
The advantage of better language support is that it's easier to
resurrect the model from the code; it doesn't give you a better or worse
model by itself.

I have a truly marvellous patch that fixes the bug which this
