Hmm, building with 4.14.10 without the patch results in:

[   19s] + make -f Makefile nv-linux.o SYSSRC=/lib/modules/4.14.10-3-
default/source SYSOUT=/usr/src/linux-obj/x86_64/default
[...]
[   88s] /home/abuild/rpmbuild/BUILD/nvidia-
gfxG04-384.98/obj/default/384.98/nvidia-uvm/uvm8_va_block.c:8771:41: error: 
implicit declaration of function 'task_stack_page' [-Werror=implicit-function-
declaration]

With the patch applied (attached for reference), the build succeeds..

Cheers,
Pete
