3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Hutchings <ben@xxxxxxxxxxxxxxx>
This reverts commit 066f289835f09a3f744d6bac96f25e25d20b3ded which was
6a040ce72598159a74969a2d01ab0ba5ee6536b3 upstream.
This was not needed and is not suitable for 3.2.y.
Reported-by: Michael Neuling <mikey@xxxxxxxxxxx>
