Hi Gerry,

Thanks for working on the framework enhancement. I am still new to
Linux (and learning :), but have extensive background in hot-plug
features on other OS for CPU, Memory, Node, RP and PCI hot-plug support.
So, I basically agree with you that we do need framework enhancement.
However, I think we need phased approach here. First, we need to make
CPU and Memory hot-plug work under the current framework. Once we
settle on the basic features, we can then make framework enhancements
without breaking the features. For CPU hotplug, I also intentionally
minimized the code changes so that the changes could be back-ported to
older kernels being used by distributions.

I will send you more comments after I reviewed your patches (which may
take some time :).
