RE: [PATCH] vsprintf: Do not break early boot with probing addresses

And I like Steven's "(fault)" idea.
How about this:

	if ptr < PAGE_SIZE		-> "(null)"
	if IS_ERR_VALUE(ptr)		-> "(fault)"

	-ss

Or:
	if (ptr < PAGE_SIZE)
		return ptr ? "(null+)" : "(null)";
	if IS_ERR_VALUE(ptr)
		return "(errno)"
