[Intel-gfx] [PATCH 4/7] drm/i915: Rip out legacy page_flip completion/irq handling

All these races and things are now solved through the vblank evasion trick, plus event handling is done using normal vblank even processing and drm_crtc_arm_vblank_event. We can get rid of all this complexity. Cc: Maarten Lankhorst Cc: Ville Syrjälä
