+Subject: intel/iommu: force writebuffer-flush quirk on Gen 4 Chipsets
+
+From: Daniel Vetter <daniel.vetter@ffwll.ch>
+
+commit 210561ffd72d00eccf12c0131b8024d5436bae95 upstream.
+
+We already have the quirk entry for the mobile platform, but also
+reports on some desktop versions. So be paranoid and set it
+everywhere.
