The HiZ buffer's allocation requirements were relaxed on Ivybridge. Following a "simple" formula in the bspec was all you needed to satisfy the requirement. To prepare the code for this, extract all places where the miptree was used, when we really only needed the region. This allows an upcoming p

Starting with Ivybridge, the hierarchical had relaxed requirements for its allocation. Following a "simple" formula in the bspec was all you needed to satisfy the requirement. To prepare the code for this, extract all places where the miptree was used, when we really only needed the region. This a
