Subject: [PATCH] drm/i915/vlv: use PIPE_START_VBLANK interrupts on VLV
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This fixes a mismatch between our vblank enable code and our IRQ
handler.  Also, since vblank start events come in before page flips
reliably, it also fixes the kms_flip plain-flip test on my BYT system.
