From: Christian Dietrich on 10 Aug 2010 08:30 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. I've been running a check on the drivers/net/stmmac sourcetree for config Items not defined in Kconfig and found such a case. Sourcecode blocks depending on these Items are not reachable from a vanilla kernel -- dead code. I've seen such dead blocks made on purpose e.g. while integrating new features into the kernel but generally they're just useless. As far as i can see in drivers/net/stmmac/Kconfig STMMAC_ETH and several depending flags are dead in the linux vanilla kernel, because it depends on CPU_SUBTYPE_ST40, but there isn't a Kconfig option for that. But f96691872439ab2071171d4531c4a95b5d493ae5 suggests, that support for this ST40 plattform was removed in 2007. There seems to be, that there was much effort on the stmmac drivers in the last few months, so i just wanted to ask if this problem is known.
