To be able to test the memory controller under NUMA, I use fake NUMA
nodes. x86-64 has a similar feature, the code I have here is the
simplest I could come up with for PowerPC.

Magnus Damm had patches from over a year ago that, I believe, made much of 
the x86_64 fake NUMA code generic so that it could be extended for 
architectures such as i386.  Perhaps he could resurrect those patches if 
there is wider interest in such a tool.

That would be a very interesting patch, but what I have here is the
simplest patch and we could build on it incrementally. The interface is
non-standard but it does amazing things for 59 lines of code change.

Well, maybe it is amazing, but having non-standard interface is also
wrong...

I tend to agree with you, but in this case it's mostly debug
infrastructure that is architecture specific.
