Pull locking updates from Ingo Molnar:
"The main changes in the locking subsystem in this cycle were:
- Add the Linux Kernel Memory Consistency Model (LKMM) subsystem,
which is an an array of tools in tools/memory-model/ that formally
describe the Linux memory coherency model (a.k.a.
Documentation/memory-barriers.txt), and also produce 'litmus tests'
in form of kernel code which can be directly executed and tested.
Here's a high level background article about an earlier version of
this work on LWN.net:
https://lwn.net/Articles/718628/
The design principles:
"There is reason to believe that Documentation/memory-barriers.txt
could use some help, and a major purpose of this patch is to
provide that help in the form of a design-time tool that can
produce all valid executions of a small fragment of concurrent
Linux-kernel code, which is called a "litmus test". This tool's
functionality is roughly similar to a full state-space search.
Please note that this is a design-time tool, not useful for
regression testing. However, we hope that the underlying
Linux-kernel memory model will be incorporated into other tools
capable of analyzing large bodies of code for regression-testing
purposes."
[...]
"A second tool is klitmus7, which converts litmus tests to
loadable kernel modules for direct testing. As with herd7, the
klitmus7 code is freely available from
http://diy.inria.fr/sources/index.html
(and via "git" at https://github.com/herd/herdtools7)"
[...]
Credits go to:
"This patch was the result of a most excellent collaboration
founded by Jade Alglave and also including Alan Stern, Andrea
Parri, and Luc Maranget."

====================
net: mvneta: improve suspend/resume
This series tries to optimize the mvneta's suspend/resume
implementation by only taking necessary actions.
Since v2:
- keep rtnl lock when calling mvneta_start_dev() and mvneta_stop_dev()
Thank Russell for pointing this out
Since v1:
- unify ret check
- try best to keep the suspend/resume behavior
- split txq deinit into sw/hw parts as well
- adjust mvneta_stop_dev() location
I didn't add Thomas's Ack tag to patch1, because in v2, I add new code
to split the txq deinit into two parts.

Current suspend/resume implementation reuses the mvneta_open() and
mvneta_close(), but it could be optimized to take only necessary
actions during suspend/resume.
One obvious problem of current implementation is: after hundreds of
system suspend/resume cycles, the resume of mvneta could fail due to
fragmented dma coherent memory. After this patch, the non-necessary
memory alloc/free is optimized out.

This is to prepare the suspend/resume improvement in next patch. The
SW parts can be optimized out during resume.
As for rxq handling during suspend, we'd like to drop packets by
calling mvneta_rxq_drop_pkts() which is both SW and HW operation,
so we don't split rxq deinit.

During transport reconnect, other processes may have registered memory
and blocked on transport. This creates a deadlock situation because the
transport resources can't be freed, and reconnect is blocked.
Fix this by returning to upper layer on timeout. Before returning,
transport status is set to reconnecting so other processes will release
memory registration resources.
Upper layer will retry the reconnect. This is not in fast I/O path so
setting the timeout to 5 seconds.

Prior to this patch, when one packet is hashed into path [1]
(hash <= nh_upper_bound) and it's neigh is dead, it will try
path [2]. However, if path [2]'s neigh is alive but it's
hash > nh_upper_bound, it will not return this alive path.
This packet will never be sent even if path [2] is alive.
3.3.3.1/24:
nexthop via 1.1.1.254 dev eth1 weight 1 <--[1] (dead neigh)
nexthop via 2.2.2.254 dev eth2 weight 1 <--[2]
With sysctl_fib_multipath_use_neigh set is supposed to find an
available path respecting to the l3/l4 hash. But if there is
no available route with this hash, it should at least return
an alive route even with other hash.
This patch is to fix it by processing fib_multipath_use_neigh
earlier than the hash check, so that it will at least return
an alive route if there is when fib_multipath_use_neigh is
enabled. It's also compatible with before when there are alive
routes with the l3/l4 hash.

mdio-bitbang mentioned 10 for both read and write.
However mdio read opcode is 10 and write opcode is 01
Fixed comment.

The sky2 ethernet stops working after system resume from suspend:
[ 582.852065] sky2 0000:04:00.0: Refused to change power state, currently in D3
The current 150ms delay is not enough, change it to 200ms can solve the
issue.

The default TX moderation mode was mistakenly set to CQE based. The
intention was to add a control ability in order to improve some specific
use-cases. In general, we prefer to use EQE based moderation as it gives
much better numbers for the common cases.
CQE based causes a degradation in the common case since it resets the
moderation timer on CQE generation. This causes an issue when TSO is
well utilized (large TSO sessions). The timer is set to 16us so traffic
of ~64KB TSO sessions per second would mean timer reset (CQE per TSO
session -> long time between CQEs). In this case we quickly reach the
tcp_limit_output_bytes (256KB by default) and cause a halt in TX traffic.
By setting EQE based moderation we make sure timer would expire after
16us regardless of the packet rate.
This fixes an up to 40% packet rate and up to 23% bandwidth degradtions.

When the driver is closed, all the associated irqs are disabled. In the
event that the driver exits a reset in the closed state, we should be
consistent with the state we are in directly after a close. So before we
exit the reset routine, all irqs should be disabled as well. This will
prevent the irqs from being enabled twice in this case and reporting a
number of noisy warning traces.
