Subject: [PATCH 2/2] printk: Remember the message level for multi-line output

printk: Remember the message level for multi-line output

    printk(KERN_ALERT "Danger Will Robinson!\nAlien Approaching!\n");

At present this will result in one message at ALERT level and one
at the current default message loglevel (e.g. WARNING). This is
non-intuitive.

Modify vprintk() to remember the message loglevel each time it
is specified and use it for subsequent lines of output which do
not specify one, within the same call to printk.
