[PATCH v5 5/6] arm64: exclusive upper bound for ptdump entries

[Maxwell Bland <mbland@motorola.com>]

Update the upper bound of all ptdump entries to not include the byte
which is actually governed by the next entry. As the lowest byte is
included and governed, this makes the size specifications exact.
