For most devices, we're running the vendor forks of the Linux kernel (mostly Android). The source of all of them is available, just like the mainline Linux kernel. With that being said, the stock Linux kernel and its vendor forks contain obfuscated code and even (small) blobs. To get rid of that we would need to package something like the Linux-libre patchset [0]. From what I know, no one is planning this currently, but if someone is interested in this, I don't think anyone in the community would be against having this as option.
