f3d4039242 tokenring: delete last holdout of CONFIG_TR
Tokenring support was deleted in v3.5. One last holdout of the macro

fbbdb8f096 net: fix compile error of implicit declaration of skb_probe_transport_header
The commit 40893fd(net: switch to use skb_probe_transport_header())
involes a new error accidently. When NET_SKBUFF_DATA_USES_OFFSE is
not enabled, below compile error happens:

  CC      net/packet/af_packet.o
  net/packet/af_packet.c: In function ‘packet_sendmsg_spkt’:
  net/packet/af_packet.c:1516:2: error: implicit declaration of function ‘skb_probe_transport_header’ [-Werror=implicit-function-declaration]
  cc1: some warnings being treated as errors
  make[2]: *** [net/packet/af_packet.o] Error 1
  make[1]: *** [net/packet] Error 2
  make: *** [net] Error 2

As it seems skb_probe_transport_header() is not related to
NET_SKBUFF_DATA_USES_OFFSE, we should move the definition of
skb_probe_transport_header() out of scope of
NET_SKBUFF_DATA_USES_OFFSE macro.

a33e6112d9 phy: Elimination the forced speed reduction algorithm.
In case of fixed speed set up for a NIC (e.g. ethtool -s eth0 autoneg off speed
100 duplex full) with an ethernet cable plugged off, the mentioned algorithm
slows down a NIC speed, so further cable hook-up leads to nonoperable link state.

68399ac37e net: frag, avoid several CPUs grabbing same frag queue during LRU evictor loop
The LRU list is protected by its own lock, since commit 3ef0eb0db4
(net: frag, move LRU list maintenance outside of rwlock), and
no-longer by a read_lock.

This makes it possible, to remove the inet_frag_queue, which is about
to be "evicted", from the LRU list head.  This avoids the problem, of
several CPUs grabbing the same frag queue.

Note, cannot remove the inet_frag_lru_del() call in fq_unlink()
called by inet_frag_kill(), because inet_frag_kill() is also used in
other situations.  Thus, we use list_del_init() to allow this
double list_del to work.

7ea600b531 Nest rename_lock inside vfsmount_lock
... lest we get livelocks between path_is_under() and d_path() and friends.

The thing is, wrt fairness lglocks are more similar to rwsems than to rwlocks;
it is possible to have thread B spin on attempt to take lock shared while thread
A is already holding it shared, if B is on lower-numbered CPU than A and there's
a thread C spinning on attempt to take the same lock exclusive.

As the result, we need consistent ordering between vfsmount_lock (lglock) and
rename_lock (seq_lock), even though everything that takes both is going to take
vfsmount_lock only shared.

330305cc4a ipv4: Fix ip-header identification for gso packets.
ip-header id needs to be incremented even if IP_DF flag is set.
This behaviour was changed in commit 490ab08127
(IP_GRE: Fix IP-Identification).

Following patch fixes it so that identification is always
incremented.

c0db64ce84 Merge branch 'stmmac'
Giuseppe CAVALLARO says:

====================
These patches enhance the driver adding the PTP support and the initial code
for RGMII/SGMII/TBI/RTBI modes.
Also this patches review the driver removing some Koption for selecting between
chain and ring modes. REally useful to validate the driver also at build time.
Before adding PTP, the extended descriptor support has been added because it
is mandatory to save HW timestamp in new dedicated descriptors. Also in this
case no Koption added.

Concerning the PTP, I have hacked/reviewed and tested many
part of these patches also verifying the back compatibility on
several HW and chips.

Concerning the SGMII/RGMII we have already discussed about the support
in the net.dev Mailing list with Byungho where these patchs were partially
analysed.
So I have only ported them against the latest net-next (and on
top of PTP). I have added some missing things: e.g. some parts of the
ethtool for ANE. As we clarified with Byungho, we will add further
enhancements on top of these patches if needed.

I have also built all against ARM/SH/X68 platforms and no issues on
ST-Boxes.

Thx goes to Rayagond that wrote and tested the PTP and to Byungho for SGMII.

V2: This Version 2 has the fixes discussed in the ML, for example:
    o completely remove the Koption... all the decisions are made at probe time
    o review the PTP patches and better organize them just in two patches
    o added all the fixes provided by Richard on PTP and CLK driver.

891434b18e stmmac: add IEEE PTPv1 and PTPv2 support.
This patch enhances the stmmac driver to support IEEE 1588-2002
PTP (Precision Time Protocol) version 1 and IEEE 1588-2008 PPT
version 2.

Precision Time Protocol(PTP),which enables precise synchronization
of clocks in measurement and control systems implemented with
technologies such as network communication,local computing,
& distributed objects.

Both PTPv1 and PTPv2 is selected at run-time using the HW capability
register.

The PTPv1 TimeStamp support can be used on chips that have the normal
descriptor structures and PTPv2 TimeStamp support can be used on chips
that have the Extended descriptors(DES4-5-6-7). All such sanity checks
are done and verified by using HW capability register.

V2: in this version the ethtool support has been included in this patch;
Koptions have been completely removed (previously added to select
PTP and PTPv2). PTPv1 and PTPv2 is now added in a single patch instead of
two patches.
get_timestamp() and get_systemtime() L/H have been combined into single APIs.

cf32deec16 stmmac: add tx_skbuff_dma to save descriptors used by PTP
This patch adds a new pointer variable called "tx_skbuff_dma" to private
data structure. This variable will holds the physical address of packet
to be transmitted & same will be used to free/unmap the memory once the
corresponding packet is transmitted by device.

Prior to this patch the descriptor buffer pointer(ie des2) itself was
being used for freeing/unmapping the buffer memory. But in case PTP v1
with normal descriptor the field(des2) will be overwritten by device
with timestamp value, hence driver will loose the buffer pointer to be
freed/unmapped.
