The patch from the bugzilla entry is not yet upstream.

Per the commentary in the bugzilla this commit makes the warning
message appear on 64-bit builds, but 32-bit has the same problem on
affected platforms (without the commit).

Bjorn has a proposed patch [1] that just downgrades the warning since
system operation does not appear to be affected.
