It never meant what it said, as it was always the total size of the
Global GTT and not a limit upon memory usage. Originally it served as a
quick guide to the largest batch that could be submitted by userspace,
an approximation to its maximum RSS, but was phrased badly. Today with
the 48b ppgtt, it is even more meaningless. Replace with a more specific
debug message; those wanting to know how much "video ram" they have
should consult the userspace libraries for the relevant approximation.
