    The idea, and much of the code came originally from:

        drm/i915: Create a vtable for i915 gtt
    
    Daniel didn't like the color of that patch series, and so I asked him to
    start something which appealed to his sense of color. The preceding
    patches are those, and now this is going on top of that.
    
    [extracted from the original commit message]
    
    One immediately obvious thing to implement is our gmch probing. The init
    function was getting massively bloated. Fundamentally, all that's needed
    from GMCH probing is the GTT size, and the stolen size. It makes design
    sense to put the mappable calculation in there as well, but the code
    turns out a bit nicer without it (IMO)
    
    The intel_gtt bridge thing is still here, but the subsequent patches
    will finish ripping that out.

    [danvet: Bikeshedded one comment (GMADR is just the PCI aperture, we
    use it for other things than just accessing tiled surfaces through a
    linear view) and cut the newly added long lines a bit. Also one
    checkpatch error.]
