So this set is pretty close to what I think we should be merging initially,

Since the last set, it makes fbcon and suspend/resume work a lot better,

I've also fixed a couple of bugs in -intel that make things work a lot

I've bashed on this a bit using kms-flip from intel-gpu-tools, hacked
to add 3 monitor support.

It still generates a fair few i915 state checker backtraces, and some
of them are fairly hard to work out, it might be we should just tone
down the state checker for encoders/connectors with no actual hw backing
