[PATCH 0/3] drm: Add panic handling

[Noralf Trønnes]

This patchset adds a way for DRM drivers to display kernel messages
during panic().

This version have lots of changes based on Daniel's review of the RFC
where he proposed a different way of interacting with the driver.

I have used this script to run some tests on the rendering code:
