70d6894d14 drm/i915: Serialize against vma moves 
Make sure that when submitting requests, we always serialize against
potential vma moves and clflushes.

Time for a i915_request_await_vma() interface!

18851edfa7 drm/i915/selftests: move gpu-write-dw into utils 
Using the gpu to write to some dword over a number of pages is rather
useful, and we already have two copies of such a thing, and we don't
want a third so move it to utils. There is probably some other stuff
also...

f1c4d157ab drm/i915: Fix up the inverse mapping for default ctx->engines[] 
The order in which we store the engines inside default_engines() for the
legacy ctx->engines[] has to match the legacy I915_EXEC_RING selector
mapping in execbuf::user_map. If we present VCS2 as being the second
instance of the video engine, legacy userspace calls that I915_EXEC_BSD2
and so we need to insert it into the second video slot.

v2: Record the legacy mapping (hopefully we can remove this need in the
future)
