I need some clarification here. It sounds like memoryless nodes work on x86, but hotplug + memoryless nodes isn't a supported use case or you're introducing it as a new use case?
Could you do that step by step?
First add the new node and ensure everything is ok and that the memory is online.
*After* that is done bring up the new processor and associate the processor with *online* memory.
We are discussing that in the original thread - http://lkml.kernel.org/r/YZN3ExwL7BiDS5nj@dhcp22.suse.cz
This patch is a a workaround that problem in the pcp code.
