These patches fix GPU hangs I'm seeing also with the *GL* version of 
CarChase on KBL GT3e, when using Ubuntu 16.04 kernel.

NOTE: those hangs don't happen when doing tests with latest drm-tip 
kernel.  Besides the older Ubuntu kernel, I'm seeing hangs also with the 
4.13 drm-tip kernel, but these have happened only since early November 
version of Mesa.
