Hi,

2.5.8-pre3 fails to link here:

init/main.o: In function `start_kernel':
init/main.o(.text.init+0x681): undefined reference to `setup_per_cpu_areas'

-Udo.

Rusty patch deleted setup_per_cpu_areas() for the UP case.  The patch
below simply adds it again.

As you could see a few lines above setup_per_cpu_areas gets defined only 
of CONFIG_SMP is set. So find the line in the function start_kernel in 
init/main.c ( about line #320 IIRC ) where setup_per_cpu_areas gets 
called and put #ifdef CONFIG_SMP and #endif around it.

Cheers,
Todor
