Patch by Andreas Faerber:

* The kernel's _start entry function expects now a second argument, the
   current CPU index. The PPC boot loader didn't initialize GPR4, passing
   its second argument, the kernel entry address, as CPU index, causing
   smp_cpu_rendezvous() to loop forever. This fix gets the PPC boot to a
   kernel debug prompt. The CPU index is currently fixed to 0.

Thanks a lot!
