From: Joe Perches on 10 Jul 2010 13:30
Remove near duplication of format string constants by using the newly
introduced vsprintf extention %pV to reduce text by 20k or so.

$ size drivers/net/mlx4/built-in.o*
text data bss dec hex filename
161367 1866 48784 212017 33c31 drivers/net/mlx4/built-in.o
142621 1866 46248 190735 2e90f drivers/net/mlx4/built-in.o.new

Use printk_once as appropriate.
Convert printks to pr_<level>, some bare printks now use pr_cont.
Remove now unused #define PFX.
