For 64bits arguments gcc caused that put_user macro works with wrong value because of optimalization. Adding volatile caused that gcc not optimized it. It is possible to use (as Blackfin do) two put_user macros with 32bits arguments but there is one more instruction which is due to duplication zero return value which is called put_user_asm macro.
