extern int blk_stack_limits(struct queue_limits *t, struct queue_limits *b,
                            sector_t offset);

This function is asking for the offset to be supplied as sector_t i.e.
in units of sectors, but this patch uses bytes.  Please either change
that to sectors as per the prototype, or if it really does want bytes,
fix the prototype to make that clear.
