The 'sc' ISDN driver relies on using readl() to access ISA I/O memory.
This has been deprecated and produced warnings since linux-2.3.23,
disabled by default since 2.4.10 and finally removed in 2.6.5.

I found this because the compiling the driver for ARM produces
a warning:

In file included from ../drivers/isdn/sc/includes.h:8:0,
                 from ../drivers/isdn/sc/init.c:13:
../arch/arm/include/asm/io.h:115:21: note: expected 'const volatile void *' but argument is of type 'long unsigned int'

It is pretty clear that this driver has not been used for a long time
and there is no point fixing it now, so let's remove it.

This module allows to insert errors in some of netdevice's notifier
events. All network drivers use these notifiers to signal various events
and to check if they are allowed, e.g. PRECHANGEMTU and CHANGEMTU
afterwards. Until recently I had to run failure tests by injecting
a custom module, but now this infrastructure makes it trivial to test
these failure paths. Some of the recent bugs I fixed were found using
this module.
Here's an example:
 $ cd /sys/kernel/debug/notifier-error-inject/netdev
 $ echo -22 > actions/NETDEV_CHANGEMTU/error
 $ ip link set eth0 mtu 1024

There are several issues in hv_netvsc driver with regards to link status
change handling:
- RNDIS_STATUS_NETWORK_CHANGE results in calling userspace helper doing
  '/etc/init.d/network restart' and this is inappropriate and broken for
  many reasons.
- link_watch infrastructure only sends one notification per second and
  in case of e.g. paired disconnect/connect events we get only one
  notification with last status. This makes it impossible to handle such
  situations in userspace.

Redo link status changes handling in the following way:
- Create a list of reconfig events in network device context.
- On a reconfig event add it to the list of events and schedule
  netvsc_link_change().
- In netvsc_link_change() ensure 2-second delay between link status
  changes.
- Handle RNDIS_STATUS_NETWORK_CHANGE as a paired disconnect/connect event.

The current unix_dgram_recvmsg does a wake up for every received
datagram. This seems wasteful as only SOCK_DGRAM client sockets in an
n:1 association with a server socket will ever wait because of the
associated condition. The patch below changes the function such that the
wake up only happens if wq_has_sleeper indicates that someone actually
wants to be notified. Testing with SOCK_SEQPACKET and SOCK_DGRAM socket
seems to confirm that this is an improvment.

net: ipmr: more cleanups and mfc netlink support

This set continues with the minor cleanups in the first 6 patches and
patch 7 adds the first new feature - MFC manipulation via netlink. It
registers NEWROUTE/DELROUTE for that purpose and uses the same semantics
as the already present netlink dump. The only new attribute that is used
is RTA_PREFSRC to denote an MFC_PROXY entry. Currently the table must
exist before adding an entry, and new tables can be created only via
setsockopt, but that will be changed in the future.
This set was tested with modified iproute2 which supports NEWROUTE/DELROUTE
for RTNL_FAMILY_IPMR.
====================

This patch adds support to add and remove MFC entries. It uses the
same attributes like the already present dump support in order to be
consistent. There's one new entry - RTA_PREFSRC, it's used to denote an
MFC_PROXY entry (see MRT_ADD_MFC vs MRT_ADD_MFC_PROXY).
The already existing infrastructure is used to create and delete the
entries, the netlink message gets converted internally to a struct mfcctl
which is used with ipmr_mfc_add/delete.
The other used attributes are:
RTA_IIF - used for mfcc_parent (when adding it's required to be valid)
RTA_SRC - used for mfcc_origin
RTA_DST - used for mfcc_mcastgrp
RTA_TABLE - the MRT table id
RTA_MULTIPATH - the "oifs" ttl array

Intel Wired LAN Driver Updates 2015-11-25

This series contains updates to fm10k, i40e and i40evf.

Alex Duyck fixes up fm10k to use napi_schedule_irqoff() instead of
napi_schedule() since the function it is called from runs from hard interrupt
context or with interrupts already disabled in netpoll.

Shannon cleans up i40e and i40evf unused cd_tunneling parameter and any code
comments that refer to it.  Then clean up a few instances of BUG_ON, based
on a Linux diatribe, especially when WARN_ON can be used.

Helin fixed a issue where using ethtool RXNFC command could let receive
flow hash could be set on disabled queues, so resolve by returning the
number of enabled queues before setting RXNFC.

Anjali fixes a MSS issue where the hardware/NVM sets a limit of no less than
256 bytes for MSS, yet the stack can send as low as 76 byte MSS.  Fixed the
issue by lowering the hardware limit to 64 bytes to avoid MDDs from firing
and causing a reset when the MSS is lower than 256.  Added a statistic to
track how many times we forced to do a write back on transmit if the
number of descriptors pending are less than a cache line.

Catherine fixes link status changes, where polling would only change link
status changes in one direction depending on what the last old data saved
off was.  This was due to the watchdog only calling link_event and not
handle_link_event.

Mitch cleans up and enhances error messages related to VF MAC/VLAN filters.

When a lot (many hundreds) of MAC or VLAN filters are added at one time,
we can overflow the Admin Queue buffer size with all the requests.
Unfortunately, the driver would then calculate the message size
incorrectly, causing it to be rejected by the PF. Furthermore, there was
no mechanism to trigger another request to allow for configuring the
rest of the filters that didn't fit into the first request.

To fix this, recalculate the correct buffer size when we detect the
overflow condition instead of just assuming the max buffer size. Also,
don't clear the request bit in adapter->aq_required when we have an
overflow, so that the rest of the filters can be processed later.
