Furthermore tiled pwrite is a (now) unused slowpath, so no one really cares. This fixes the last swizzling issues I have with i-g-t on my bit17 swizzling i915G. No regression, it's been broken since the dawn of gem, but it's nice for regression tracking when really _all_ i-g-t tests work. Actually this is not true, Chris Wilson noticed while reviewing this patch that the commit commit d9e86c0ee60f323e890484628f351bf50fa9a15d Author: Chris Wilson Date: Wed Nov 10 16:40:20 2010 +0000 drm/i915: Pipelined fencing [infrastructure] contained a functional change that broke things.
