[Mesa-dev] [RFC PATCH 03/40] i965/gen7.5: Pass resource streamer enable flags on batchbuffer start

[Abdiel Janulgue]

This is passed on the kernel to enable the resource streamer enable bit
on MI_BATCHBUFFER_START

v3: Use I915_EXEC_RESOURCE_STREAMER. Kernel folks want the batchbuffer
    flags to be more concise.
