AFAIR we decided to store config files just for cases when patch doesn't lays on new kernel config, for easier troubleshootong. > So I would like to see the Berning-xx.yy.zz.config-variant files > disappear from the git repository.

Most platforms (including future builds for embeded platforms like SOHO routers) are non-SMP tiny boxes, except i686/x86_64 that are targeted to use on 'big routers'.
