From: John Harrison <John.C.Harrison@xxxxxxxxx> Assorted patches to make the tree more friendly to the GPU scheduler. The biggest change is to re-organise the execbuff code path. Basically, the scheduler needs to split the submission path into two sections which are essentially software only (data structure creation, manipulation, etc.) and hardware only (actually writing the commands to the write / execlist). As this is not a small change, any other changes to the execution code path tend to cause merge conflicts and other such headaches for the scheduler. Thus it would be extremely useful to get this preparation work committed to the tree while the scheduler is still being re-worked for upstream acceptability. The other patches in the series are various minor fixes that were spotted along the way to getting the scheduler working.
