Sam Bradshaw f45c40a92d mtip32xx: minor performance enhancements ... This patch adds the following: 1) Compiler hinting in the fast path. 2) A prefetch of port->flags to eliminate moderate cpu stalling later in mtip_hw_submit_io(). 3) Eliminate a redundant rq_data_dir(). 4) Reorder members of driver_data to eliminate false cacheline sharing between irq_workers_active and unal_qdepth. With some workload and topology configurations, I'm seeing ~1.5% throughput improvement in small block random read benchmarks as well as improved latency std. dev.
