Auto merge of #127546 - workingjubilee:5-level-paging-exists, r=saethlin

Correct outdated object size limit

The comment here about 48 bit addresses being enough was written in 2016 but was made incorrect in 2019 by 5-level paging, and then persisted for another 5 years before being noticed and corrected.

The bolding of the "exclusive" part is merely to call attention to something I missed when reading it and doublechecking the math.
