At least in the Linux Kernel Mailing list there are several discussions
on Futex (e.g. non-existing Futex). Astonishingly, even for x86 archs
there have been several patches to cure problems.

If they show up that does not mean there really is a valid
implementation. I don't know which archs are provided with the "Linus
Tree", but  at least with some "embedded" Kernels trees there only is
some dummy code, just providing an error.
