Takashi found a bug in it:

--- a/lib/vsprintf.c~add-new-string-functions-strict_strto-and-convert-kernel-params-to-use-them-fix-2
+++ a/lib/vsprintf.c
@@ -234,7 +234,7 @@ int strict_strto##type(const char *cp, u
 		if (ret != 0)						\
 			*res = -(*res);					\
 	} else								\
-		ret = strict_strtou##type(cp+1, base, res);		\
+		ret = strict_strtou##type(cp, base, res);		\
 									\
 	return ret;							\
 }									\
_

and I was very bad and didn't immediately prepare and upload the fix and
hence probably wasted a lot of your time, for which I apologise.  In my
defense, it was 4:00AM Sunday and I had lost eye control by then.

Does that fix fix it?  If not: patch overboard.
