Adding a singleton for a pr_fmt #define constant string and
updating the printk subsystem to prepend that constant string
to each use of a pr_<level> at runtime would be an improvement
as it could reduce constant data used by the format strings.

That would be a _real_ improvement.

Please try to implement something like that before submitting
more of these incorrect patches.
