Subject: [PATCH] drm/i915: Refactor gen2 to gen4 vblank interrupt handling
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The indentation is getting way too deep. Pull the vblank interupt
handling out to separate functions.

v2: Keep flip_mask handling in the main irq handler and
    flatten {i8xx,i915}_handle_vblank() even further.
