Yes, the type for processor is needed, see the patch I have now commited.

Ok. I've just to apply your patches and copy my cpu_number() function in kern/cpu_number.h.
The latest compilation problems have disappeared, but there are any errors yet.

It will have to contain the assembler code to get the CPU number indeed.

Now we have to add the cpu_number() function in this file.

There is no need to declare it twice.  I have just declared it in a
proper place instead.
