But move the programming back to the vertical blank interrupt handler.
And signal the flip as being completed immediately after programming it
to the hardware.
This way we don't have to guess whether or not the hardware will
execute
the flip in a given vertical blank period, avoiding a whole lot of
trouble.
Also, not using the page flip interrupt anymore avoids problems due to
completing page flips earlier than expected by userspace.

Michel,
against which tree is this first one?
Don't apply clean on 3.16-rc2.
Can't find this in 'my' source (radeon_display.c).
radeon_crtc->flip_status = RADEON_FLIP_SUBMITTED; <<<
spin_unlock_irqrestore(&crtc->dev->event_lock, flags);
up_read(&rdev->exclusive_lock);
Thanks,
Dieter
