Supposing I want to make a change to the Kernel code and make sure that it all builds (i.e. that I did not cause any compile errors under any configuration), what's best way to do that?  Can I just take the default setting for all config options or does there exist a "build everything" mode?

you can do make allyesconfig which is about as close to build everything as you can get. Of course this still will only build for one particular architecture - so to build all architectures you would need to iterate over ARCH= . thx! hofrat
