Well, the real point is that anyone doing a test on such high kernel 
addresses is almost certainly buggy anyway.  I guess a more precise 
statement is that it returns well-defined results for any va the calling 
code could reasonably be using, not for any random bit pattern.
But I think we're getting into the weeds here.
