We now only use it from ib_alloc_pd to create a local DMA lkey if the
device doesn't provide one, or a global rkey if the ULP requests it.
This patch removes ib_get_dma_mr and open codes the functionality in
ib_alloc_pd so that we can simplify the code and prevent abuse of the
functionality. As a side effect we can also simplify things by removing
the valid access bit check, and the PD refcounting.
In the future I hope to also remove the per-PD global MR entirely by
shifting this work into the HW drivers, as one step towards avoiding
the struct ib_mr overload for various different use cases.

net: hns: Add support of ACPI to HNS driver RoCE Reset function
In the Hip06 SoC, the RoCE Engine is part of the Hisilicon Network
Subsystem and is dependent upon DSAF module. Therefore, certain
functions like RESET are exposed through the common registers of
HNS DSAF module which are memory-mapped by the HNS driver and
currently can only be accessed through DT/syscon interface.
This patch adds the support of ACPI to the existing RoCE reset
function in the HNS driver(please refer NOTE 2). Hisilicon RoCE
driver (please refer NOTE 1) shall call this reset function during
probe time to reset the RoCE Engine.
The HNS Reset function indirectly ends up in calling the _DSM()
function part of the DSDT ACPI Table. Actual reset functionality
for ACPI is implemented within the ACPI DSDT Table which also has
been enhanced to support this change.
Support of ACPI in the HNS RoCE driver shall be pushed through a
different accompanying below patch:

Merge branch '40GbE' of git://git./linux/kernel/git/jkirsher/next-queue
Jeff Kirsher says:
====================
40GbE Intel Wired LAN Driver Updates 2016-08-19
This series contains updates to i40e and i40evf only.
Jake provides several patches, first just moves a function to co-locate
the two functions related to configuring RSS via the admin queue, which
should help in spotting bugs when comparing the two functions. Fixed
an issue where commit
e69ff813af35 ("i40e: rework the functions to
configure RSS with similar parameters") missed checking whether the seed
is NULL before using it and did not use the passed in *lut parameter.
Fixed an issue where a previous refactor missed i40e_vsi_config_rss()
and the values were being ignored, so checked for the fields and used
them instead of default values. Lastly replaced calls to
create_singlethread_workqueue() with alloc_workqueue() to provide more
control over workqueue creation and allows explicit setting of the
desired mode of operation.
Mitch adds link speed to log messages and reports speed through ethtool.
Carolyn refactors tail bump check and fixes byte ordering problems found
when enabling this feature support. Adds support for HMC resources and
profile commands for x722 firmware.
Heinrich Schuchardt fixes format identifiers from %u to %d since the
variable is defined as an integer.
Catherine fixes an issue where there was a race condition between the
completion of the client open and calls to the client ops, so ensured
that client ops are not called until we are sure client is open.
Harshitha makes sure that i40e_client_release() does not try to use
an adapter pointer which may not be initialized, so make sure it is.
Joe Perches fixes the use of the local macro XSTRINGIFY() to use
__stringify() instead.
Avinash corrects the mutex usage in client_subtask(). Fixed the RDMA
client to open again after reset since it is closed during a PF reset.
Jeff (me) clean up whitespace issues, where indentation was done
inconsistently and with spaces versus tabs.

samples/bpf: Add tunnel set/get tests.
The patch creates sample code exercising bpf_skb_{set,get}_tunnel_key,
and bpf_skb_{set,get}_tunnel_opt for GRE, VXLAN, and GENEVE. A native
tunnel device is created in a namespace to interact with a lwtunnel
device out of the namespace, with metadata enabled. The bpf_skb_set_*
program is attached to tc egress and bpf_skb_get_* is attached to egress
qdisc. A ping between two tunnels is used to verify correctness and
the result of bpf_skb_get_* printed by bpf_trace_printk.

hv_netvsc: Implement batching of receive completions
The existing code uses busy retry when unable to send out receive
completions due to full ring buffer. It also gives up retrying after limit
is reached, and causes receive buffer slots not being recycled.
This patch implements batching of receive completions. It also prevents
dropping receive completions due to full ring buffer.
