It compiles completely. :-)

Just a point : in the file arch/i383/process.c, I added the  following 
lines.

#include <asm/tlbflush.h>
#include <asm/cpu.h>

My original processs.c file seems to be a little be bit different from 
yours (?).
The following line was already in the process.c file.

+#include <asm/atomic_kmap.h>

Thanks
