Of course you have to do it for your running kernel version
Or go this way
but for that you will have to install the linux headers
sudo pacman -S $(pacman -Qsq "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ')
You will be able to do this while using phone tethering, so you get internet access …
