Try to duplicate the CentOS  kernel's config instead of using/creating your
own, you probably missed one or more needed config item.

Or better, use rpm/rpm source from elrepo (google for the url). It takes
stable/mainline kernel and make it (as much as possible) work with CentOS

Mind you that CentOS 7 is based on 3.10.x kernel and you're trying to run
5.x kernel, something that might not work due to incompatibility of API/ABI

Hope it helps
