    drm/i915: call drm_handle_vblank before finish_page_flip · 74d44445

    ... since finish_page_flip needs the vblank timestamp generated
    in drm_handle_vblank. Somehow all the gmch platforms get it right,
    but all the pch platform irq handlers get is wrong. Hooray for copy&
    pasting!
    
    Currently this gets papered over by a gross hack in finish_page_flip.
    A second patch will remove that.
    
    Note that without this, the new timestamp sanity checks in flip_test
    occasionally get tripped up, hence the cc: stable tag.
