Hallo,

I have problems with linking of kernel 2.5.8-usagi. Compilation ended with:

ld -m elf_i386 -T /usr/src/usagi/kernel/linux25/arch/i386/vmlinux.lds -e stext arch/i386/kernel/head.o arch/i386/kernel/init_task.o init/main.o

init/version.o init/do_mounts.o \
        --start-group \
        arch/i386/kernel/kernel.o arch/i386/mm/mm.o kernel/kernel.o
mm/mm.o fs/fs.o ipc/ipc.o \
        /usr/src/usagi/kernel/linux25/arch/i386/lib/lib.a

init/main.o: In function `start_kernel':
init/main.o(.text.init+0x5db): undefined reference to `setup_per_cpu_areas'
make: *** [vmlinux] Error 1

You can use the attached (text/plain) patch to fix this.

Thanks
