extract and use FILE_LINE macro
Extract nifty FILE_LINE useful for printk style debugging:
printk("%s\n", FILE_LINE);
It should not be used en mass probably because __FILE__ string literals
can be merged while FILE_LINE's won't. But for debugging it is what
the doctor ordered.
Don't add leading and trailing underscores, they're painful to type.
Trust me, I've tried both versions.
