For a few restructured text warnings in mac80211, making the

In order to not add trailing whitespace, but also not introduce

====================
bpf: add longest prefix match map
This patch set adds a longest prefix match algorithm that can be used
to match IP addresses to a stored set of ranges. It is exposed as a
bpf map type.
Internally, data is stored in an unbalanced tree of nodes that has a
maximum height of n, where n is the prefixlen the trie was created
with.
Note that this has nothing to do with fib or fib6 and is in no way meant
to replace or share code with it. It's rather a much simpler
implementation that is specifically written with bpf maps in mind.
Patch 1/2 adds the implementation, 2/2 an extensive test suite and 3/3
has benchmarking code for the new trie type.
Feedback is much appreciated.
Changelog:
v3 -> v4:
* David added a 3rd patch that augments map_perf_test for
LPM trie benchmarks
* Limit allocation of maps of this new type to CAP_SYS_ADMIN
for now, as requested by Alexei
* Add a stub .map_delete_elem so the core does not stumble
over a NULL pointer when the syscall is invoked
* Tests for non-power-of-2 prefix lengths were added
* More comment style fixes
v2 -> v3:
* Store both the key match data and the caller provided
value in the same byte array attached to a node. This
avoids double allocations
* Bring back node->flags to distinguish between 'real'
and intermediate nodes
* Fix comment style and some typos
v1 -> v2:
* Turn spin lock into raw spinlock
* Lock with irqsave options during trie_update_elem()
* Return -ENOMEM properly from trie_alloc()
* Force attr->flags == BPF_F_NO_PREALLOC during creation
* Set trie->map.pages after creation to account for map memory
* Allow arbitrary value sizes
* Removed node->flags and denode intermediate nodes through
node->value == NULL instead
rfc -> v1:
* Add __rcu pointer annotations to make sparse happy
* Fold _lpm_trie_find_target_node() into its only caller
* Fix some minor documentation issues

Extend the map_perf_test_{user,kern}.c infrastructure to stress test
lpm-trie lookups. We hook into the kprobe on sys_gettid() and measure
the latency depending on trie size and lookup count.
On my Intel Haswell i7-6400U, a single gettid() syscall with an empty
bpf program takes roughly 6.5us on my system. Lookups in empty tries
take ~1.8us on first try, ~0.9us on retries. Lookups in tries with 8192
entries take ~7.1us (on the first _and_ any subsequent try).

The first part of this program runs randomized tests against the
lpm-bpf-map. It implements a "Trivial Longest Prefix Match" (tlpm)
based on simple, linear, single linked lists. The implementation
should be pretty straightforward.
Based on tlpm, this inserts randomized data into bpf-lpm-maps and
verifies the trie-based bpf-map implementation behaves the same way
as tlpm.
The second part uses 'real world' IPv4 and IPv6 addresses and tests
the trie with those.

This trie implements a longest prefix match algorithm that can be used
to match IP addresses to a stored set of ranges.
Internally, data is stored in an unbalanced trie of nodes that has a
maximum height of n, where n is the prefixlen the trie was created
with.
Tries may be created with prefix lengths that are multiples of 8, in
the range from 8 to 2048. The key used for lookup and update operations
is a struct bpf_lpm_trie_key, and the value is a uint64_t.
The code carries more information about the internal implementation.

The EMAC has an internal PHY that is often called the "SGMII". This
SGMII is also connected to an external PHY, which is managed by phylib.
These dual PHYs often cause confusion. In this case, the data structure
for managing the SGMII was mis-named and located in the wrong header file.
Structure emac_phy is renamed to emac_sgmii to clearly indicate it applies
to the internal PHY only. It also also moved from emac_phy.h (which
supports the external PHY) to emac_sgmii.h (where it belongs).
To keep the changes minimal, only the structure name is changed, not
the names of any variables of that type.

- no full-blown UniMAC, instead we have the MagicPacket matching from UniMAC at
same offset, and a GMII Interface Block (GIB) for the MAC-level stuff, since
we are always interfaced to an Ethernet switch which is fully Ethernet compliant
shortcuts could be made
- 16 transmit queues, whose interrupts are moved into the first Level-2 interrupt
controller bank
- slight TDMA offset change (a register was inserted after TDMA_STATUS, *sigh*)
- 256 RX descriptors (512 words) and 256 TX descriptors (not visible)
As a consequence of these two things, update the code paths accordingly to
differentiate the full-blown from the light version.

net: dsa: Move temperature sensor code into PHY.
Marvell Ethernet switches contain a temperature sensor. There appears
to be one sensor, which is shared by each of the internal PHYs. Each
PHY has independent registers to read this sensor, and to set a limit
for when an alarm should be raised.
Some Marvell discrete PHY also have the same sensor and registers.
Moving the HWMON code from DSA into the PHY makes the sensor available
in discrete PHYs, and removes the layering violation, the switch
driver poking around in PHY registers.
While moving the code into the PHY driver, it has been re-written to
use the new HWMON APIs.

tipc: emulate multicast through replication
TIPC multicast messages are currently distributed via L2 broadcast
or IP multicast to all nodes in the cluster, irrespective of the
number of real destinations of the message.
In this series we introduce an option to transport messages via
replication ("replicast") across a selected number of unicast links,
instead of relying on the underlying media. This option is used when
true broadcast/multicast is not supported by the media, or when the
number of true destinations is much smaller than the cluster size.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

If the bearer carrying multicast messages supports broadcast, those
messages will be sent to all cluster nodes, irrespective of whether
these nodes host any actual destinations socket or not. This is clearly
wasteful if the cluster is large and there are only a few real
destinations for the message being sent.
In this commit we extend the eligibility of the newly introduced
"replicast" transmit option. We now make it possible for a user to
select which method he wants to be used, either as a mandatory setting
via setsockopt(), or as a relative setting where we let the broadcast
layer decide which method to use based on the ratio between cluster
size and the message's actual number of destination nodes.
In the latter case, a sending socket must stick to a previously
selected method until it enters an idle period of at least 5 seconds.
This eliminates the risk of message reordering caused by method change,
i.e., when changes to cluster size or number of destinations would
otherwise mandate a new method to be used.

TIPC multicast messages are currently carried over a reliable
'broadcast link', making use of the underlying media's ability to
transport packets as L2 broadcast or IP multicast to all nodes in
the cluster.
When the used bearer is lacking that ability, we can instead emulate
the broadcast service by replicating and sending the packets over as
many unicast links as needed to reach all identified destinations.
We now introduce a new TIPC link-level 'replicast' service that does
this.
