Does arch apply its own patches to an official kernel?

If I let makepkg download linux source, say for 5.2.arch2-1, are there patches that were applied by arch, but not by upstream?

https://git.archlinux.org/linux.git/log/?h=v5.2-arch2

Currently there is one backported patch and two for runtime configuration for unprivileged user namespaces,

Crude but effective:

#!/bin/bash
if [[ -z $1 ]]; then
	echo "Must provide the numerical version for comparison as first token"
	echo
	echo "$0 4.18.1"
	exit 1
fi

MPATH=/incoming

cd "$MPATH/arch-git/linux" || exit 1
rm -f 000*.patch
git pull
#git remote add stable https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
git fetch --tags stable
git fetch --tags
git format-patch v"$1"..v"$1"-arch1

In the case of 5.2-arch2:

% git format-patch v5.2..v5.2-arch2
0001-add-sysctl-to-disallow-unprivileged-CLONE_NEWUSER-by.patch
0002-ZEN-Add-CONFIG-for-unprivileged_userns_clone.patch
0003-iwlwifi-mvm-disable-TX-AMSDU-on-older-NICs.patch
0004-Arch-Linux-kernel-v5.2-arch2.patch

The above give specifics, but a more broad answer to the title question is "Yes, but they are kept to a minimum"
