This is a user space application to kernel interface question. We are
using linux-2.6.17.11 in our design and have two boards. One 8241 and
one 8541.

In user space, we need to use the system call "sys_futex", but when the
user space application is compiled we have an unresolved linkage error.

Can someone offer a suggestion on the care and feeding of "sys_futex" in
a ppc 8241/8541 environment.

Thanks.
