2.6.10, alpha, "Relocation overflows" - .data.percpu ?

[David Monro]

Ahh! good, I was beginning to think I was going mad :)

Yes I know I can work around it by building them in rather than having 
them as modules, but thats not really the  point. They _should_ work 
fine as modules.

My guess is that this isn't anything to do with the compiler, but is 
some sort of issue with the way that elf section is either defined or 
loaded. Which means I am _way_ out of my depth and wouldn't have a clue 
what to do next :)

Cheers,

	David
