memmove and strncpy is probably inclined by gcc. There is an implemetation
of them in /usr/src/linux/lib/string.c that you can paste into a file (like
xfs_deb.c) to make them work.

Can you list where the kernel_flag is used on smp computers. And I see that
you have defined __SMP__ when building the module. Is your computer a SMP
computer (if not, try adding the flag --disable-smp) to the configure
script). 

You should also find kernel_flag i /proc/ksyms, if not you should add a
line like

#ifdef __SMP__
EXPORT_SYMBOL(kernel_flag);
#endif

in to the S/390 equivalent of /usr/src/linux/arch/i386/kernel/i386_ksyms.c
and rebuild your kernel, don't forget to run ``make dep''.

But first you should start try run ``arlad -tz'' (test-mode) to see if
arlad works first.

The warning message isn't really that much to care about, the lwp warnings
isn't that good, but if you can run the test program (lwp/testlwp) that
should be perfectly ok).
