ARGH!
I haven't followed this thread closely, so just a random comment from me. An argument from some is that they want to boot Linux on the big CPU to be quicker. The most convenient is to have the big CPU at 0.
I suppose that's almost sensible ;-) I just despair at the amount of variation that's allowed.
I'm guessing that swapping cpus in the bootloader or someplace really early is equally hard in that we (Linux) assume we boot on cpu 0 or something like that?
