From 4b16f8e2d6d64249f0ed3ca7fe2a319d0dde2719 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Fri, 22 Jul 2011 18:24:23 -0400 Subject: powerpc: various straight conversions from module.h --> export.h All these files were including module.h just for the basic EXPORT_SYMBOL infrastructure. We can shift them off to the export.h header which is a way smaller footprint and thus realize some compile time gains.

So now this flag is a NOOP and can be removed.
