Hello Harry,
could you please download again the patch and try again?
It seems I missed a bit...

And, please, compile again qemu any time beacause I'm not sure how much 
are exposed to userland "struct thread" and "struct proc", for this problem.

You should firstly try the canonical case of kernel clean compilation 
(so with KSE) and kqemu clean compilation (so without KSE, without the 
-DKSE option).

Let me know,
Thanks.

Attilio
