[Intel-gfx] [PATCH 00/10] Prep work patches for GPU scheduler

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

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.
