+Subject: Revert "perf test 6: Fix missing kvm module load for s390"
+
+This reverts commit 9a501cdb05348fa8f85db8df5a82f4b8cd11594e.
+
+Which was upstream commit 53fe307dfd309e425b171f6272d64296a54f4dff.
+
+Ben Hutchings reports that this commit depends on new code added in
+v4.18, and so is irrelevant on older kernels, and breaks the build.
