+From cb350a8989adbd65db574325d9a86d5437d800da Mon Sep 17 00:00:00 2001
+From: Guillem Jover <guillem@hadrons.org>
+Date: Mon, 13 Sep 2021 23:56:08 +0200
+Subject: [PATCH] test: Use syscall wrappers instead of using syscall(2)
+ directly
+
+Some of these syscalls have different entry points depending on the
+architecture. Use the wrappers to avoid having to reimplement them
+portably.
+
+Fixes build failures on Debian armel and armhf builds.
