Since mlx4 NIC are used on PowerPC with 64K pages, we need to adapt
MLX4_EN_ALLOC_PREFER_ORDER definition.
Otherwise, a fragment sitting in an out of order TCP queue can hold
0.5 Mbytes and it is a serious OOM risk.

40GbE Intel Wired LAN Driver Updates 2017-02-18
This series contains updates to i40e and i40evf only.
Alan fixes a bug in which the driver is unable to exit overflow
promiscuous mode after having added "too many" mac filters. Ractored
the '%*ph' printk format specifier to instead use the print_hex_dump().
Josh adds enabling multicast magic packet wakeup by adding calls to
the mac_address_write admin q function during power down to update the
PRTPM_SAH/SAL registers with the MC_MAG_EN bit.
Jake remove a duplicate call i40e_update_link_info(), since it does not
need to call it twice. Fixes and issue where we calculating the wrong
switch id on big endian platforms. Avoided sparse warning, by doing a
typecast to ensure the value is of the type expected by
csum_replace_by_diff().
Mitch fixes a memory leak by freeing resources during i40e_remove().
Cleans up some code confusion by adding a proper code comment.
Carolyn fixes a bug introduced with the addition of the per queue ITR
feature support in ethtool. Cleans up a duplicate device id from the
PCI table.
Harshitha fixes a bug which causes the 'Link Detected' field in
ethtool to report the correct link status.
Benjamin Poirier from SuSE applies a fix ec13ee80145c ("virtio_net:
invoke softirqs after __napi_schedule") to i40e driver as well.

Resizing currently drops consumer lock. This can cause entries to be
reordered, which isn't good in itself. More importantly, consumer can
detect a false ring empty condition and block forever.
Further, nesting of consumer within producer lock is problematic for
tun, since it produces entries in a BH, which causes a lock order
reversal:
CPU0 CPU1
---- ----
consume:
lock(&(&r->consumer_lock)->rlock);
resize:
local_irq_disable();
lock(&(&r->producer_lock)->rlock);
lock(&(&r->consumer_lock)->rlock);
<Interrupt>
produce:
lock(&(&r->producer_lock)->rlock);
To fix, nest producer lock within consumer lock during resize,
and keep consumer lock during the whole swap operation.

sctp: support MSG_MORE flag when sending msg
This patch is to add support for MSG_MORE on sctp. Patch 1/2 is an
improvement ahead of patch 2/2 to solve the close block problem
mentioned in https://patchwork.ozlabs.org/patch/372404/.

This patch is to add support for MSG_MORE on sctp.
It adds force_delay in sctp_datamsg to save MSG_MORE, and sets it after
creating datamsg according to the send flag. sctp_packet_can_append_data
then uses it to decide if the chunks of this msg will be sent at once or
delay it.
Note that unlike [1], this patch saves MSG_MORE in datamsg, instead of
in assoc. As sctp enqueues the chunks first, then dequeue them one by
one. If it's saved in assoc,the current msg's send flag (MSG_MORE) may
affect other chunks' bundling.
Since last patch, sctp flush out queue once assoc state falls into
SHUTDOWN_PENDING, the close block problem mentioned in [1] has been
solved as well.

This patch is to flush out queue when assoc state falls into
SHUTDOWN_PENDING if there are still chunks in it, so that the
data can be sent out as soon as possible before sending SHUTDOWN
chunk.
When sctp supports MSG_MORE flag in next patch, this improvement
can also solve the problem that the chunks with MSG_MORE flag
may be stuck in queue when closing an assoc.

Move that check from the function into its caller and replace

By doing this also adjust the functions return value from int to void

net: phy: Fix PHY unbind crash
This fixes crashes when the PHY driver is no longer bound to the device.
There is still a fair amount of work to be done to get the unbind -> bind
sequent to result in a functional state, but that will be net-next material.
These two problems existed for as long as PHYLIB as been around.

There are number of function calls, originating from user-space,
typically through the Ethernet driver that can make us crash by
dereferencing phydev->drv which will be NULL once we unbind the driver
from the PHY.
There are still functional issues that prevent an unbind then rebind to
work, but these will be addressed separately.

The PHY library does not deal very well with bind and unbind events. The first
thing we would see is that we were not properly canceling the PHY state machine
workqueue, so we would be crashing while dereferencing phydev->drv since there
is no driver attached anymore.

Fix PER tracing of system calls after git commit 34525e1f7e8dc478

The Makefile in drivers/s390 has:
obj-y += cio/ block/ char/ crypto/ net/ scsi/ virtio/
and the Makefile in crypto/ has:
ap-objs := ap_bus.o ap_card.o ap_queue.o
meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.
Also note that MODULE_ALIAS is a no-op for non-module builds.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
We replace module.h with moduleparam.h since the file does declare
some module parameters even though it is not modular itself.

sctp has changed to use rhlist for transport rhashtable since commit
7fda702f9315 ("sctp: use new rhlist interface on sctp transport
rhashtable").
But rhltable_insert_key doesn't check the duplicate node when inserting
a node, unlike rhashtable_lookup_insert_key. It may cause duplicate
assoc/transport in rhashtable. like:
client (addr A, B) server (addr X, Y)
connect to X INIT (1)
------------>
connect to Y INIT (2)
------------>
INIT_ACK (1)
<------------
INIT_ACK (2)
<------------
After sending INIT (2), one transport will be created and hashed into
rhashtable. But when receiving INIT_ACK (1) and processing the address
params, another transport will be created and hashed into rhashtable
with the same addr Y and EP as the last transport. This will confuse
the assoc/transport's lookup.
This patch is to fix it by returning err if any duplicate node exists
before inserting it.

Now when sending a packet, sctp_transport_dst_check will check if dst
is obsolete by calling ipv4/ip6_dst_check. But they return obsolete
only when adding a new cache, after that when the cache's pmtu is
updated again, it will not trigger transport->dst/pmtu's update.
It can be reproduced by reducing route's pmtu twice. At the 1st time
client will add a new cache, and transport->pathmtu gets updated as
sctp_transport_dst_check finds it's obsolete. But at the 2nd time,
cache's mtu is updated, sctp client will never send out any packet,
because transport->pmtu has no chance to update.
This patch is to fix this by also checking if transport pmtu is dst
mtu in sctp_transport_dst_check, so that transport->pmtu can be
updated on time.

====================
sctp: add receiver-side procedures for stream reconf ssn reset request chunk
Patch 3/7 and 4/7 are to implement receiver-side procedures for the
Outgoing and Incoming SSN Reset Request Parameter described in rfc6525
section 5.2.2 and 5.2.3
Patch 1/7 and 2/7 are ahead of them to define some apis.
Patch 5/7-7/7 are to add the process of reconf chunk event in rx path.
Note that with this patchset, asoc->reconf_enable has no chance yet to
be set, until the patch "sctp: add get and set sockopt for reconf_enable"
is applied in the future. As we can not just enable it when sctp is not
capable of processing reconf chunk yet.
v1->v2:
- re-split the patchset and make sure it has no dead codes for review.
- rename the titles of the commits and improve some changelogs.
- drop __packed from some structures in patch 1/7.
- fix some kbuild warnings in patch 3/7 by initializing str_p = NULL.
- sctp_chunk_lookup_strreset_param changes to return sctp_paramhdr_t *
and uses sctp_strreset_tsnreq to access request_seq in patch 3/7.
- use __u<size> in uapi sctp.h in patch 1/7.
- do str_list endian conversion when generating stream_reset_event in patch
2/7.
- remove str_list endian conversion, pass resp_seq param with network endian
to lookup_strreset_param in 3/7.
- move str_list endian conversion out of sctp_make_strreset_req, so that
sctp_make_strreset_req can be used more conveniently to process inreq in
patch 4/7.
- remove sctp_merge_reconf_chunk and not support response with multiparam
in patch 6/7.
