    intel_stub: Claim to support I915_PARAM_HAS_CONTEXT_ISOLATION. · 8d986c8c

    Modern kernels support I915_PARAM_HAS_CONTEXT_ISOLATION, which allows
    us to whack certain context registers with impunity.  One of those is
    INSTPM/CS_DEBUG_MODE2, which controls whether Constant Buffer 0 is
    relative to dynamic state base address, or a general GPU address.
    If it's relative (the default), we can only push 3 ranges of UBOs.
    If it's absolute, we can push 4.  So this affects our shader output.
    
    Follow the behavior of modern kernels and allow us to push all 4 ranges.
