I dislike this patch.

It's _mostly_ ok, but the nmi naming is nasty.

Either "printk_nmi()" or "printk_safe" is fine, but doing *both* is
stupid and wrong. And you do both in a couple of places.

So please keep the printk_nmi_enter/exit() naming. Because
"printk_safe_nmi_enter/exit()" is just stupid.  It's about nmi entry.
The "safe" part is simply an implementation detail.
