I am fine with exporting default topology information for all
architectures.

I just wanted to avoid pollution of sysfs with useless information
when this information is not provided on an architecture.

Further thoughts -- e.g. concerning the MULTI_NODE_CPU config option?

If I provide defaults for cpu_node_id, cpu_node_siblings etc. the
config option becomes rather useless and I'll remove it.


Regards,
Andreas
