I think I already responded to Helge before and yes, I think that parisc doesn't do anything special for fork, vfork, clone, and by extension also probably doesn't need to for clone3. It should only be a problem for arches that require mucking explicitly with arguments of clone-like syscalls. In any case, I saw Helge's patch and I think I might've missed to add an Acked-by but feel free to add it. Thanks for testing it and sorry that I couldn't test! Christian
