Yep, that the source of the problem. What is happening is that the other sparc64 KBUILD_CFLAGS (such as -mcmodel=medlow, etc.) are only legal during a 64-bit compile. When compiling 32-bit those options are not allowed. -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
