Thank you for the patch. It's a pity you haven't post it earlier
as I lost few hours fixing missing topology_init.

Anyway, it is a huge improvement other the current state of
official kernel. Is this patch on its way to the kernel?

I was not so lucky. I was able to boot and two cpus were detected
 (Supersparc II) but the machine opened PROM console after
mounting tmpfs filesystem (for the /tmp directory). The harddisk
filesystems were mounted correctly. I will try to look into this
problem.
