[Intel-gfx] [PATCH] A possible hotfix for aliasing PPGTT in kernel 4.11.x or 4.10.x

[Zhi Wang]

Redhat guys have choose kernel stable 4.10 as their target. As you know,
currently the aliasing PPGTT mode required by GVT-g doesn't work now.

Thanks Chris who has already pushed the fixes, but it seems that the
kernel 4.11 merging window has already open and those fixes might be
merged in 4.12.x possibly which is too late for us. T_T

After some discussions with Zhiyuan and Zhenyu, we wonder that if it's
possible to send this hotfix patch to kernel 4.11 *fixes* to make
aliasing PPGTT work temporarily and after Chris' fixes merged in future,
we or he can revert or drop this patch then. Is this possible?

Or we can see if there is any option for us. Thank you guys!
