Sorry for slow response on this. In general regarding this topic.
Microblaze is soft core CPU (now there are hardcore versions too but not
running Linux). I believe there could be Numa system with
microblaze/microblazes (SMP is not supported in mainline).

This code was added in 2011 which is pretty hard to remember why it was
done in this way.

It compiles but not working on HW. Please take a look at log below.

Thanks,
Michal
