Frist -misc pull for 4.8, with pretty much just random all over plus a few
more lockless gem BO patches acked/reviewed by driver maintainers.

I'm starting a bit earlier this time around because there's a few invasive
patch series to land (nonblocking atomic prep work, fence prep work,
rst/sphinx kerneldoc finally happening) and I need a baseline with all the
branches merged.
