I really don't like this. What if the format already does have a '\n'? And
what if some other CPU is printing at the same time?
I'd almost be open to adding a "flags" field to vprintk, and allow setting
things like "finish line with \n" there. Or perhaps even better, have a
"vprintk_line()" function that does it with no dynamic flags. Maybe make
it static, and move all these panic helper funtions into kernel/printk.c
(since this really is a special case).
I dunno. I'm just throwing out suggestions. I just don't think the above
patch is very nice.
