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?
