using ezbench, gfxbench3, bxt J3455, 1920x1080 fullscreen, bare Xorg

perf doesn't suggest any contention in the kernel, and does not appear to be
ratelimited by i915.ko submission overhead, i.e. if it was the locking changes
I expected that to be reflected in the perf profile of i915.ko. Hmm.

The system does have a pair of dimm, and so I hope dual-channel!
