Hi Alan

I found one way to break the circularity. The association of type and struct
definitions with interlocking inline functions caused the problem. This
extracts task_struct from linux/sched.h to its own header,
linux/task_struct.h. There are a few modifications elsewhere to support
this. I'm not sure all the changes were necessary, but they are working as I
write:

I don't have access to a real SMP Athlon box, so I'd appreciate test reports
on the real thing. I expect some polishing will be needed.

Cheers,
Tom
