No. Let me grab a PowerVM box, test and get back. > > Has this always been broken, or did we break it in a particular commit? If the > latter can you tell me which commit. memory_hotplug_max() got introduced in cd34206e9 and has been buggy since then.

I am not sure as only PowerKVM is affected with the introducion of DDW feature in yet-to-be-released QEMU-2.7. Even there, we are working around the problem within QEMU itself, but better to fix this in the kernel once.
