[drm-next-4.10-wip / linus master + x86 PAT v1.1 patches][AMDGPU CIK] - piglit test - streaming-texture-leak deadlock GPU

[Shawn Starr]

Hello AMD folks,

Using latest LLVM trunk/Mesa master and latest changes from drm-next-4.10-wip available, I am unable to run piglit concurrently, causes GPU graphics pipe to get pegged 100%.

Running: streaming-texture-leak -auto 3 times, wedges GPU.
