You could use "m<>" here, but maybe just dropping "%Un" is better. > +#ifdef __powerpc64__ > +#define __put_user_asm2_goto(x, ptr, label) \ > + __put_user_asm_goto(x, ptr, label, "std") > +#else /* __powerpc64__ */ > +#define __put_user_asm2_goto(x, addr, label) \ > + asm volatile goto( \ > + "1: stw%U1%X1 %0, %1\n" \ > + "2: stw%U1%X1 %L0, %L1\n" \ > + EX_TABLE(1b, %l2) \ > + EX_TABLE(2b, %l2) \ > + : \ > + : "r" (x), "m" (*addr) \ > + : \ > + : label) > +#endif /* __powerpc64__ */ Here, you should drop it for sure.
