OK, so I'm a little late to the party, apologies.

Minor nit (from someone who has been spending a lot of time in futex.c
trying to clean things up recently :-).  Let's not comment each argument
individually.  It needlessly lengthens the code.  The interested user
can easily look up alloc_large_system_hash.  If you feel a comment is
really needed, consider a single line before the call... I gave this
some thought and couldn't think of anything you could put there that
wouldn't still send the interested reader over to page_alloc.c.

/* Allocate futex hashtable with... <whatever is special about this> */
futex_queues = alloc_large_system_hash("futexes",
				       sizeof(struct futex_hash_bucket),
				       nr_slots, 0, 0, NULL, &futex_hash_mask,
				       nr_slots);
