    drm/i915/selftests: Reduce the volume of the timeout message
    
    Originally it was anticipated that timeouts would be a rare event, and
    so merit a warning that the test was incomplete. However, for igt we
    keep the timeout low, and hitting the timeout is intentional. It no
    longer necessitates a warning, but to be expected.

Actually still being reported as dmesg-warn, but that's not a kernel bug. Rather it is an incorrect classification by piglit/test-runner.

Sorry Chris, I have to reopen this so that the wrong classification of the dmesg can be solved. 

Petri, I assign this to you.

These prints shouldn't trigger dmesg-warn:

[ 2703.245979] Setting dangerous option mock_selftests - tainting kernel
[ 2704.275796] sg_alloc_table timed out
[ 2705.276793] i915_sg_trim timed out

    drm/i915/selftests: Downgrade igt_timeout message
    
    Give in, since CI continues to incorrectly insist that KERN_NOTICE is a
    warning and flags the timeout message as unwanted spam. At first, the
    intention was to use the message to indicate which tests might warrant
    an extended run, but virtually all tests require a timeout so it is
    simply not as interesting as first thought.
