So in testing this patchset against 4.12-rc6, w/ HiKey (so I had a bit of fuzz on one patch, and skipped the drm_vblank changes and the entire exynos patch), it seems to work ok. I rebooted 10 times and didn't see the initialization race where multiple fbs were created that I could regularly trigger before.
