Subject[PATCH 4.9 44/83] Revert "perf test 6: Fix missing kvm module load for s390"
Date
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.
