A recent commit added a sysfs_emit and sysfs_emit_at to allow various sysfs show functions to ensure that the PAGE_SIZE buffer argument is never overrun and always NUL terminated. Convert the RDMA/InfiniBand subsystem to use these new functions. The first 2 patches exclusively used coccinelle to convert uses. The third and fourth patches were done manually.
