Kernel threads do have an address space. It’s just that they all share the same one. This does not prevent them from each having a different stack.
Text and data are laid out in the kernel address space (the one that is shared by all the threads), depending on how and when it was allocated, and what it’s used for.
The Linux MM site has a lot of documentation about this aspect of Linux. Head over there.
