    fb: Rework locking to fix lock ordering on takeover

    Adjust the console layer to allow a take over call where the caller already
    holds the locks. Make the fb layer lock in order.

    This s partly a band aid, the fb layer is terminally confused about the
    locking rules it uses for its notifiers it seems.

This version works for me too - thanks.

I was planning to test it last night, but new code in mm/ failed horribly and
was BUG()ing all over the place, so I didn't get any significant testing
of this patch done.

Will update...

Nothing complains anywhere, looks great.


Thanks,
Sasha
