I agree that it would be nicer, however I think the SUNs will never be booted on CPU1 anyway? Anyways, I think this should go into another patch series.


You cannot assume this, sun4d and AFAIK all 64bit systems will boot on
the first non-blacklisted CPU found.
For example, it is perfectly OK to have no CPU present on board0 slot0
in which case the SS1000 will boot using CPU1.

Sorry I meant the UP 32-bit SUNs, some if not all SMP 32-bit SUNs apparently use the boot_cpu_id Sam is talking about. Have you tried booting on CPU1 with a UP Linux kernel on the SS1000 machine?

I still believe that the changes should go into a separate patch series though.

Thanks,
Daniel
