e12fcff799 drm/radeon: Unbreak HPD handling for r600+
We end up reading the interrupt register for HPD5, and then writing it
to HPD6 which on systems without anything using HPD5 results in
permanently disabling hotplug on one of the display outputs after the
first time we acknowledge a hotplug interrupt from the GPU.

This code is really bad. But for now, let's just fix this. I will
hopefully have a large patch series to refactor all of this soon.

7b8cd3363e drm/i915: Make vblank evade warnings optional
Add a new Kconfig option to enable/disable the extra warnings
from the vblank evade code. For now we'll keep the warning
about an actually missed vblank always enabled as that can have
an actual user visible impact. But if we miss the deadline
othrwise there's no real need to bother the user with that.
We'll want these warnings enabled during development however
so that we can catch regressions.

Based on the reports it looks like this is still very easy
to hit on SKL, so we have more work ahead of us to optimize
the crtiical section further.

330bdf62fe drm/nouveau/tmr: avoid processing completed alarms when adding a new one
The idea here was to avoid having to "manually" program the HW if there's
a new earliest alarm.  This was lazy and bad, as it leads to loads of fun
races between inter-related callers (ie. therm).

Turns out, it's not so difficult after all.  Go figure ;)

e6db95799b drm/nouveau/kms/nv50: skip core channel cursor update on position-only changes
The DRM core used to only call prepare_fb/cleanup_fb() when a plane's
framebuffer changed, which achieved the desired effect.

It's apparently now up to the driver to decide on its own.

36601c2b36 drm/nouveau/kms/nv50: fix source-rect-only plane updates
This "optimisation" (which was originally meant to skip updating cursor
settings in the core channel on position-only updates) turned out to be
pointless in the final design of the code before it was merged.

Remove it completely, as it breaks other cases.

30514decb2 drm/amdgpu: fix dependency issue
The problem is that executing the jobs in the right order doesn't give you the right result
because consecutive jobs executed on the same engine are pipelined.
In other words job B does it buffer read before job A has written it's result.
