Subject: Re: [PATCH] cleanup legacy console_print function
Here you go!

Subject: cleanup console_print()
console_print() is an old legacy interface mostly unused in the entire
kernel tree. It's best to clean up its existing use and let developers
use their own implementation of it as they feel fit.
