[GIT PULL] gvt fix for 4.14-rc6

[Zhi Wang]

Hi:
     Here are some fixes for 4.14-rc6. Zhenyu's patch fixes the 
per_ctx_bb check in GVT-g since the usage of per_ctx_bb in i915 has been 
changed recently. Another two patches from Xiong fix the GPU hang of 
linxu guest when it's running large workload.

Thanks,
Zhi.
