Oh, I tried to elaborate on the idea in the cover letter, that using the defconfig as base and then configure the rest as modules is to get a bootable kernel that have as many features turned on as possible. That will make it possible to run as wide a range of testsuites as possible on a single kernel.
Does that make it clearer ?
