This is a re-spin of part of earlier i965-isl work concentrating only on gen6 stencil surfaces.
1) Instead of introducing the layout in ISL patches 5, 6 and 15 simply add the concept locally to i965. Jason expected to see proper layout in ISL - patch 15 adds one but to i965. 2) Instead of adding intermediate on-demand offset/size calculators for the current layout, this series skips all that and goes directly to back-to-back (which is represented using ISL). 3) Offsetting doesn't need extra arguments to be sprinkled all over the driver but manages locally examining the layout type - see patch 15 (Jason suggested this, only instead of ISL, it is now local to i965). 4) Legacy mapping table logic is refactored and re-used. Patch 3 could be moved to i965 but I thought it generic enough to fit ISL as well. Patch 17 addresses this time stencil only making it clearer what is really needed (and what is not). Patch 19 is really a RFC for now - I believe something of that sort is preferred by Chad, Jason and Nanley (ISL authors). I'm still in doubt. Having a real patch helps to make certain we are all on the same page. Sorry for the churn.
