Thank you. > I'll incorporate it in next submission. We should add the following so we are complaint to the ILP32 ABI dealing with pointers don't have to be zero extended for arguments, Note ZERO should most likely be ZERO_PTR or something to do that effect, I am not so good with names. #ifdef __LP64__ #define ZERO(n) #else #define ZERO(n) mov w##n, w##n #endif ... ENTRY(__kernel_gettimeofday) .cfi_startproc ZERO(0) ZERO(1) ... ENTRY(__kernel_clock_gettime) .cfi_startproc ZERO(1) ... ENTRY(__kernel_clock_getres) .cfi_startproc ZERO(1) Thanks, Andrew Pinski > > Yury. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
