Work with John Stultz to upstream a Linux kernel config fragment manager and rework the yocto-kernel-tools to use it. This will simplify our tooling and increase our usage/test base.
The patch has been pulled into akpm's tree. Currently waiting for that to merge to Linus' tree. Will update accordingly.
akpm pushed to Linus and the various merge_config related patches have been merged upstream, starting with: 4b5f72145e3ba85e38240dba844ebe1fcbb73713 kconfig: add merge_config.sh script
