--- Comment #4 from Chris Wilson <chris at chris-wilson.co.uk> ---
To get past the mmap failure, needs a libdrm fix or the ddx w/a. However, that
crash should not happen, so:

    sna: Initialise no-op callbacks early

    In case of error, we try to free up memory before trying again. This
    involves callbacks into higher level code - but if we fail early, we
    will not have those hooks installed. Set no-ops stubs early to prevent
    untimely crashes.
