    alpha: simplify fork and friends · e0e431aa
    Al Viro authored
    * no need to restore everything from switch_stack when we only need $26
    * no need to pass current_pt_regs() manually, we can just as easily
    calculate it in alpha_clone/alpha_vfork ($8 + constant)
    * interpretation of zero usp as "use the parent's" is simpler in copy_thread();
    let fork and vfork just pass 0.
