--- Comment #3 from Konstantin Belousov <kib at FreeBSD.org> ---
(In reply to CTurt from comment #2)
Suppose that uap->start is > 0x80000000, and uap->length is large enough so
that the sum appears under the 3 pages * 8.  Then negative i falls under the
loop condition and causes wrong accesses.

WRT return of success in this case, right, thank you for noting, I will fix it
as well.
