From: Christoph Egger on 26 Apr 2010 10:10 Hi all! As part of the VAMOS[0] research project at the University of Erlangen we are looking at multiple integrity errors in linux' configuration system. The following patch removes a unnecessary conditional. Inside a block making sure CONFIG_64 isn't set the option is checked again and based on that some parts are (not) included. As the outer check already makes sure CONFIG_64 isn't set here both checks are unnecessary so this patch removes them. Please keep me informed of this patch getting confirmed / merged so we can keep track of it.

So the check is actually useless and potentially irritation.
