+Subject: [PATCH] Add qatomic support for AArch64 (aka arm64).
+
+Patch by Mark Salter <msalter@redhat.com>
+licensed under BSD:
+
+<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=735488#195>
+
+This patch is known to not be the most correct way
+to implement them, as it seems to be possible to do it in a faster way,
+but should work non the less until we can provide something better.
