+Subject: [PATCH] rteval: Don't restrict measurement threads to inherited
+ cpumask
+
+This patch reverses be811d28a471cfcaf7960289e00960e7f5b18f03
+
+This patch syncs rteval to 795433f50f20ef7598db5cfe991b5386e4080d41 in
+rt-tests
+
+If the user does not specify a cpumask, rteval will still run on the
+cpus according to the cpumask inherited from the runtime environment.
+However, if the user specifies a cpumask, then it will overwrite the
+runtime environment where allowed.
+
+This will allow the user to run measurement threads on isolated cpus.
