Not easy, if it was removed from the repo. I modified my mhwd-kernel script, but here is a standalone script:
#!/bin/bash
kver_list=( $(pacman -Ssq "^linux[0-9][0-9]?([0-9])($|-rt$)" | \
sed -r "s/linux([4,5])([0-9]+)(|-rt)/\\1.\\2\\3/g") )
kver_inst=( $(pacman -Qqs "^linux[0-9][0-9]?([0-9])($|-rt$)" | \
sed -r "s/linux([4,5])([0-9]+)(|-rt)/\\1.\\2\\3/g") )
# Remove installed kernels from the list
for target in ${kver_inst[@]}; do
for i in "${!kver_list[@]}"; do
if [[ ${kver_list[i]} == $target ]]; then
unset 'kver_list[i]'
fi
done
done
# List kernels versions, which are not installed
echo -e "The following kernels are \033[1mNOT INSTALLED\033[0m in your system:"

done

echo -e "The following kernels are \033[1mINSTALLED\033[0m in your system:"

echo "If the files don't have a known version number, then they are most likely garbage."
echo "Same goes for not installed kernel versions."
echo
read -p "Would you like to delete these files? [ENTER/CTRL+C]"
sudo rm -fv ${garbage[@]}
read -p "Would you like to recreate the initcpio? [ENTER/CTRL+C]"
sudo mkinitcpio -P
read -p "Would you like to recreate the grub config? [ENTER/CTRL+C]"
sudo grub-mkconfig -o /boot/grub/grub.cfg
else
echo "No garbage found."
fi
Save it into a text file and run it in chroot or on the local installation:
bash script
like this:
cd /tmp
nano script
Copy the text and insert it with CTRL+SHIFT+V and save and exit it with CTRL+S and CTRL+X,
Then run it.
It looks like this then:
$ bash script
