Perhaps a better way is to use CM's kernel.mk in /build and make use of the TARGET_KERNEL_ADDITIONAL_CONFIG option which appends to the main defconfig.

create $(KERNEL_SRC)/arch/arm64/configs/copperheados_debug_config with the extras you want, and add this to device repo:

# Enable debug on debug builds
ifneq ($(TARGET_BUILD_VARIANT),user)
TARGET_KERNEL_ADDITIONAL_CONFIG := copperheados_debug_config
endif

This also gives you inline kernel build without the need to modify the kernel as it is automatically picked up during build.

(or just copy the relevant parts to each kernel's AndroidKernel.mk.)
