Subject: [PATCH 0/2] blk-mq: small optimization for accessing of queue map

Hi Jens

These two patches are small optimization for accessing the queue mapping
in hot path. It saves the queue mapping results into blk_mq_ctx directly,
then we needn't do the complicated bounce on queue_hw_ctx[] map[] and
mq_map[].
