Add #define pr_fmt(fmt) as appropriate.
Add "IPv6: " to appropriate files.
Convert printk(KERN_<LEVEL> to pr_<level> (but not KERN_DEBUG).
Standardize on "%s: " not "%s(): " when emitting __func__.
Use "%s: ", __func__ instead of embedding function name.
Coalesce formats, align arguments.
ADDRCONF output is now prefixed with "IPv6: "

This changes the action of the system. By default:
printk(KERN_DEBUG "foo\n");
is enabled all the time and prints to log with debug level.
But your version
pr_debug("foo\n");
defaults to being dropped until the system is built with dynamic
debug, and that particular debug instance is enabled.
Since these are all useful, but low priority messages, not I
don't think disabling them by default is such a great idea now.
