From 7c5ff4a2c588c89d00ab0e0dd61f44942233d63d Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 30 Jan 2017 10:44:57 +0000 Subject: [PATCH] drm/i915: Mark the kernel as tainted if we fail the preproduction check MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Preproduction sdv are not supported beyond the release of production hardware, and continued use is ill-advised. Mark the kernel as tainted to reinforce the error.
