The pointer math in this statemet does a divide;
	struct hfi1_ipoib_txq *txq = &priv->txqs[napi - priv->tx_napis];

Elminate the divide by embedding the struct napi_strut in the txq and
getting the txq with a container_of() using the newly embedded napi.

This patch removes kmem cache allocation and deallocation in favor of
having the ipoib_txreq in the ring.

The consumer is now the packet sending side allocating tx descriptors from
ring and the producer is the napi interrupt handling freeing tx
descriptors.

The locks are now eliminated because the napi tx lock insures a single
consumer and the napi handling insures a single producer.

The napi poll is converted to memory poll looking for items that have been
marked completed.

For fast memory regions create duplicate mapping tables so ib_map_mr_sg()
can build a new mapping table which is then swapped into place
synchronously with the execution of an IB_WR_REG_MR work request.

Currently the rxe driver uses the same table for receiving RDMA operations
and for building new tables in preparation for reusing the MR. This
exposes users to potentially incorrect results.

Earlier patches added memory barriers to protect user space to kernel
space communications. The user space queues were previously shown to have
occasional memory synchonization errors which were removed by adding
smp_load_acquire, smp_store_release barriers.  This patch extends that to
the case where queues are used between kernel space threads.

This patch also extends the queue types to include kernel ULP queues which
access the other end of the queues in kernel verbs calls like poll_cq and
post_send/recv.

When the FRMR is allocated with single page, driver is attempting to

Driver has 1ms delay between the polling for atomic command completion.
Polling immediately after issuing command usually doesn't report any
completions. So all commands in the blocking path needs two iterations. So
effectively 1ms spend on each command. HW requires much lesser time for
each command. So reduce the delay to 1us and increase the iteration count
to wait for the same time.

To pick the change in:

  7957d93b ("block: add ioctl to read the disk sequence number")

It adds a new ioctl, but we are still not using that to generate tables
for 'perf trace', so no changes in tooling.

This silences this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/fs.h' differs from latest version at 'include/uapi/linux/fs.h'
  diff -u tools/include/uapi/linux/fs.h include/uapi/linux/fs.h
