This patch series is the second installment of my quest to clean up the i915 uAPI. The first three patches delete interfaces which have only ever been used by i-g-t and never any real userspace. In the case of NO_ZEROMAP, it's unclear exactly how this happened. There were userspace patches for it back in the day, they just never landed. For the others, there was never any userspace beyond i-g-t and they never should have landed in the first place.
The last patch moves the SINGLE_TIMELINE API to an emulation using syncobj to help simplify some of our locking infrastructure.
