No, this is not going to be acceptable, I'm afraid. This tells blk-mq
that the driver always needs blocking context for queueing IO, which
will increase latencies for the cases where we'd otherwise issue IO

the issue was that the PIO code could not handle
highmem. That's not the case anymore, so this should be fine.
