I think this fell through the cracks and so no. Note that generally we
feature-freeze drm tree around -rc6 anyway for the upcoming merge window,
so you were cutting this all a bit close anyway. Also looks like the ttm
kmap caching question didn't get resolved?

Anyway if patches are stuck resend with RESEND and if people still don't
pick them up poke me and I'll apply as fallback.

Cheers, Daniel
