lttng-instrumentation-sh.patch issue

Applying the lttng-instrumentation-sh.patch there is a duplicated call
of do_fork function in SH arch code (see below).
------------------------------------------------------------------------

int kernel_thread(int (*fn)(void *), void * arg, unsigned long flags)
{
        unsigned long pid;
        struct pt_regs regs;

        memset(&regs, 0, sizeof(regs));
        regs.regs[4] = (unsigned long)arg;
        regs.regs[5] = (unsigned long)fn;

        regs.pc = (unsigned long)kernel_thread_helper;
        regs.sr = (1 << 30);

        /* Ok, create the new process.. */
        return do_fork(flags | CLONE_VM | CLONE_UNTRACED, 0,   <<<<<
These two lines have to be removed
                       &regs, 0, NULL, NULL);                  <<<<<
(as i386 does for example).
        pid =  do_fork(flags | CLONE_VM | CLONE_UNTRACED, 0,
                       &regs, 0, NULL, NULL);
        trace_mark(kernel_arch_kthread_create, "pid %ld fn %p", pid, fn);
        return pid;
}
