After scan the "arch/" sub-directory, except arc, the cris, c6x, frv, and parisc are also use ';' as comments, I guess they will welcome this patch. And some of another architectures may use '#', '|', '!', '@' or "//" as line comment mark. It seems most of them support ';' as newline in the macro, but it is also necessary to give a check. If this patch is applied, I will/should sync all the related architectures to let ASM_NL consistency. :-) Thanks. -- Chen Gang -- 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
