Re: [PATCH 3/4] drm/i915: handle walking compact dma scatter lists

So far the assumption was that each dma scatter list entry contains only a single page. This might not hold in the future, when we'll introduce compact scatter lists, so prepare for this everywhere in the i915 code where we walk such a list.

We'll fix the place _creating_ these lists separately in the next patch to help the reviewing/bisectability.

Can you please reassure me that i-g-t/tests/gem_exec_lut_handle is not too adversely affected (on a wide range of cpus). -Chris
