[Intel-gfx] [PATCH 19/22] drm/i915/gem: Separate the ww_mutex walker into its own list

In preparation for making eb_vma bigger and heavy to run inn parallel, we need to stop apply an in-place swap() to reorder around ww_mutex deadlocks. Keep the array intact and reorder the locks using a dedicated list. Signed-off-by: Chris Wilson --- .../gpu/drm/i915/gem/i915_gem_execbuffer.c
