+From 0b7a1e0d3463aa8aa4b7dcad0ec154e658d68036 Mon Sep 17 00:00:00 2001
+From: Kurt Kanzenbach <k...@kmk-computers.de>
+Date: Wed, 1 Apr 2020 20:15:24 +0200
+Subject: [PATCH] all: Fix musl build
+
+There are a few problems:
+
+ * pi stress: pthread_attr_setaffinity_np() is not supported
+ * cyclictest: SIGEV_THREAD_ID is not supported
+ * hackbench: Fix include
+ * all: Fix sched_* calls
+
+With these changes applied, the rt-tests seem to run fine.
