[Intel-gfx] [PATCH 0/4] drm/i915: Fix async flip wm0/ddb optimization

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Turns out the async flip wm0/ddb optimization doesn't work
at all currently. Let's fix it. It also had problems with
leaving SAGV on mistakenly but those were handled via a
separate series since it was a more generic issue.
