Subject: [PATCH] drm/i915: refactor ilk display interrupt handling
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

- Use a for_each_loop and add the corresponding #defines.
- Drop the _ILK postfix on the existing DE_PIPE_VBLANK macro for
  consistency with everything else.
- Also use macros (and add the missing one for plane flips) for the
  ivb display interrupt handler.
