    drm/nouveau/core: rework event interface · 79ca2770

    This is a lot of prep-work for being able to send event notifications
    back to userspace.  Events now contain data, rather than a "something
    just happened" signal.
    Handler data is now embedded into a containing structure, rather than
    being kmalloc()'d, and can optionally have the notify routine handled
    in a workqueue.
    Various races between suspend/unload with display HPD/DP IRQ handlers
    automagically solved as a result.
