Well, yet it is adopted for non-debug builds de facto :\

The thing is the presence of the printk is not the real problem. It only tells you the mapping is inexistent. The problem is if in debug build you don't see at all this message (assuming you have kpti enabled). This would mean you would overwrite a random page.
