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:

This enables panic message output for fb cma helper framebuffers.

This adds support for outputting kernel messages on panic().
A circular buffer is used to collect kernel messages.
On panic() the notifier function loops over each DRM device and
it's crtc's to find suitable framebuffers. On the next
console->write(), the messages in the circular buffer are rendere
This enables panic message output support in simpledrm.

On Terra Mobile Ultrabook 1450 II (Core i5-3337U, i915 devid = 0x166),
the screen is tiled in many 480Ã320 screens (like a mosaic) since v4.7.
This laptop is simply unusable.
I have bisected the cause to commit a05628195a0d ("drm/i915: Get
panel_type from OpRegion panel details").
Like for Skyla
