The problem remains, the file is still too damn big, and it's hard to draw the lines what to extract. Maybe all the modeset code needs to be lifted, along with the config compare, but then I think that has too many dependencies to axe out cleanly. Damned if you do, damned if you don't.

I've also got a patch to move intel_modeset_setup_hw_state() and all the static functions only it calls to another file. Do you also think that needs to be together with the modeset code...?

Do you also think that > needs to be together with the modeset code...? Readout+sanitation... I guess that's pretty self contained so a fairly good candidate for moving out. Though it does mean I get to rebase my "nuke the legacy state pointers" branch at some point :/ Oh well, that's life.
