Linux Kernel Configuration
└─>General architecture-dependent options
└─>HAVE_MOD_ARCH_SPECIFIC
In linux kernel since version 3.1 (release Date: 2011-10-24)  
The arch uses struct mod_arch_specific to store data. Many arches
just need a simple module loader without arch specific data - those
should not enable this.
