See http://www.infradead.org/rpr.html Pass a queue_limits to blk_mq_init_queue and apply it if non-NULL. This will allow allocating queues with valid queue limits instead of setting the values one at a time later. Also rename the function to blk_mq_alloc_queue as that is a much better name for a function that allocates a queue and always pass the queuedata argument instead of having a separate version for the extra argument.
