I see. As you say, user tools need to support messages output in multiple lines for SMP environments even if this patch set is introduced.
Please do not mix the both and do not apply these patches.
OK, I'll make important messages with KERN_CONT or no-prefix printk() output those in single line. Thanks, Yoshihiro YUNOMAE -- Yoshihiro YUNOMAE Software Platform Research Dept.
