Rework excecbuf slightly to take all locks earlier and stop dropping our lookups,
which allows us to do a more effective try-loop.

We will also need to lock all gem bo's in advance, including the shadow bo for the
command buffer submission. This is done before replacing struct_mutex by ww locking,
for increased readability.

Chris Wilson (2):
  drm/i915: Drop inspection of execbuf flags during evict
  drm/i915/gem: Extract transient execbuf flags from i915_vma

Maarten Lankhorst (5):
  drm/i915: Add an implementation for i915_gem_ww_ctx locking, v2.
  drm/i915: Remove locking from i915_gem_object_prepare_read/write
  drm/i915: Separate lookup and pinning in execbuf.
  drm/i915: Parse command buffer earlier in eb_relocate(slow)
  drm/i915: Use per object locking instead of struct_mutex for execbuf
