Of course is arg 4 in r10.

That's the prototype in process.c. From the user level it is
int clone(int flags, unsigned long newsp, void *parent_tid, void
*child_tid, void *tlsaddr)

You don't get it. The parameter which is passed on is the TLS address
which does not appear in the parameter list but is passed in the *fifth*
parameter. TLS address != child_tid! The patch is correct and
regardless of what ak said, please apply it. Unlike ak's claims it is
actually tested. I'm running such a kernel and threads actually work
(unlike with the original kernel).
