I don't want to have to require that all __attribute__((section)) storage be initialised - people will surely forget to do it and things will slip through. If we really do have a problem here it'd be better to fix it in some central and global fashion: either by ensuring that each architecture's startup code will zero this memory or by some compiler/linker option such as -fno-common. - To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
