Ah, OK. I eventually came across a mention in one of the patches of running
a separate instance of Linux on each core, whick left me even more mystified.
But the above clarifies it, thanks...

I wonder how many currently global variables will need to be moved to per_cpu
structures to make it work, and how intrusive that will end up. Or is the plan
to have the boot loader simply plonk the entire .data/.bss in different locations
for each core?
