I think it would probably be better to separate these into the x86 support
(patch 2, part of 3, 4, 5, and patch 7) and the generic memory hotplug,
cpu, and documentation (patch 1, most of 3, wiring up in 4 and 5, patch
7). In each changelog you can talk about the entire scope of the feature
and what each patch is leading to, but this separation will help to get it
merged first by the x86 maintainers and then the generic bits through the
-mm tree.
