I'm wondering whether we should avoid moving module_signature.c and 
leave it in kernel/ as this file is used even when CONFIG_MODULES is not 
selected, and he is the only one like this.

Keeping it outside of kernel/module/ would allow to conditionaly build 
entire kernel/module/ based of CONFIG_MODULES and then avoid all checks 
against CONFIG_MODULES which look misleading at times.
