So I applied these commits in order against the drm-tip as of 8d527b772ec330 .
I had a merge error in the first patch related to commit e7abf8141935d in
drivers/gpu/drm/i915/gt/intel_gt_pm.c , but I fixed it up easily enough.

So I booted into it, used it for about 5 mins, then suspended the machine ...
and it never came back.

You'd think that since Intel was among the companies pushing this S3
"improvement" that there'd be a box there somewhere to test against s01x
regressions (including the commit referenced in the initial bug).

... ah well
