d57170b1b1 openvswitch: Use RCU lock for flow dump operation.
Flow dump operation is read-only operation.  There is no need to
take ovs-lock.  Following patch use rcu-lock for dumping flows.

4bf93b50fd nilfs2: fix issue with counting number of bio requests for BIO_EOPNOTSUPP error detection
Fix the issue with improper counting number of flying bio requests for
BIO_EOPNOTSUPP error detection case.

The sb_nbio must be incremented exactly the same number of times as
complete() function was called (or will be called) because
nilfs_segbuf_wait() will call wail_for_completion() for the number of
times set to sb_nbio:

  do {
      wait_for_completion(&segbuf->sb_bio_event);
  } while (--segbuf->sb_nbio > 0);

Two functions complete() and wait_for_completion() must be called the
same number of times for the same sb_bio_event.  Otherwise,
wait_for_completion() will hang or leak.

93dbc1b3b5 drivers/platform/olpc/olpc-ec.c: initialise earlier
Being a low-level component, various drivers (e.g.  olpc-battery) assume
that it is ok to communicate with the OLPC Embedded Controller during
probe.  Therefore the OLPC EC driver must be initialised before other
drivers try to use it.  This was the case until it was recently moved
out of arch/x86 and restructured around commits ac2504151f ("Platform:
OLPC: turn EC driver into a platform_driver") and 85f90cf6ca ("x86:
OLPC: switch over to using new EC driver on x86").

Use arch_initcall so that olpc-ec is readied earlier, matching the
previous behaviour.

Fixes a regression introduced in Linux-3.6 where various drivers such as
olpc-battery and olpc-xo1-sci failed to load due to an inability to
communicate with the EC.  The user-visible effect was a lack of battery
monitoring, missing ebook/lid switch input devices, etc.

d70b7616d9 mac80211: ignore (E)CSA in probe response frames
Seth reports that some APs, notably the Netgear WNDAP360, send
invalid ECSA IEs in probe response frames with the operating
class and channel number both set to zero, even when no channel
switch is being done. As a result, any scan while connected to
such an AP results in the connection being dropped.

Fix this by ignoring any channel switch announcment in probe
response frames entirely, since we're connected to the AP we
will be receiving a beacon (and maybe even an action frame) if
a channel switch is done, which is sufficient.

1fb9026000 mac80211: move setting WIPHY_FLAG_SUPPORTS_SCHED_SCAN into drivers
mac80211 currently sets WIPHY_FLAG_SUPPORTS_SCHED_SCAN based on whether
the start_sched_scan operation is supported or not, but that will not
be correct for all drivers, we're adding scheduled scan to the iwlmvm
driver but it depends on firmware support.

Therefore, move setting WIPHY_FLAG_SUPPORTS_SCHED_SCAN into the drivers
so that they can control it regardless of implementing the operation.

This currently only affects the TI drivers since they're the only ones
implementing scheduled scan (in a mac80211 driver.)

IP sends device configuration (see inet_fill_link_af) as an array
in the netlink information, but the indices in that array are not

but was broken by:

by a later addition of devconf support for IPV4

0f7cc9a3c2 tcp: increase throughput when reordering is high
The stack currently detects reordering and avoid spurious
retransmission very well. However the throughput is sub-optimal under
high reordering because cwnd is increased only if the data is deliverd
in order. I.e., FLAG_DATA_ACKED check in tcp_ack().  The more packet
are reordered the worse the throughput is.

Therefore when reordering is proven high, cwnd should advance whenever
the data is delivered regardless of its ordering. If reordering is low,
conservatively advance cwnd only on ordered deliveries in Open state,
and retain cwnd in Disordered state (RFC5681).

Using netperf on a qdisc setup of 20Mbps BW and random RTT from 45ms
to 55ms (for reordering effect). This change increases TCP throughput
by 20 - 25% to near bottleneck BW.

A special case is the stretched ACK with new SACK and/or ECE mark.
For example, a receiver may receive an out of order or ECN packet with
unacked data buffered because of LRO or delayed ACK. The principle on
such an ACK is to advance cwnd on the cummulative acked part first,
then reduce cwnd in tcp_fastretrans_alert().

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates

This series contains updates to igb and e1000e.

Akeem provides 3 igb patches, the first resets the link when EEE is enabled
or disabled if the link is up.  His second patch changes a register read
which normally stores of the read value to "just-read" so that hardware
can accurately latch the register read.  Lastly, he adds rcu_lock to avoid
a possible race condition with igb_update_stats function.

Mitch provides a fix for SR-IOV, where MSI-X interrupts are required, so
make sure that MSI-X is enabled before allowing the user to turn on SR-IOV.

Alex's igb patch make it so that we limit the lower bound for max_frame_size
to the size of a standard Ethernet frame.  This allows for feature parity
with other Intel based drivers such as ixgbe.

Carolyn adds a SKU for a flashless i210 device and a fix for get_fw_version()
so that it works for all parts for igb.  In addition, she has 2 igb patches
to refactor NVM code to accommodate devices with no flash.  Lastly, she
adds code to check for the failure of pci_disable_link_state() to attempt
to work around a problem found with some systems.

Laura provides the remaining 2 igb patches.  One removing the hard-coded
value for the size of the RETA indirection table, and creates a macro instead
for the RETA indirection table.  The second adds the ethtool callbacks
necessary to change the RETA indirection table from userspace.

Bruce fixes a whitespace issue in a recent commit and resolves a jiffies
comparison warning by using time_after().

Li provides a fix for e1000e to avoid a kernel crash on shutdown by adding
one more check in e1000e_shutdown().  This is due to e1000e_shutdown()
trying to clear correctable errors on the upstream P2P bridge, when under
some cases we do not have the upstream P2P bridge.

v2:
 - fixed patch 11 conditional statement from < to <= based on feedback
   from Ben Hutchings
 - fixed patch 12 patch description (adding the commit summary) based
   on feedback from Sergei Shtylyov

1211c96117 mwifiex: do not create AP and P2P interfaces upon driver loading
Bug 60747 - 1286:2044 [Microsoft Surface Pro]
    Marvell 88W8797 wifi show 3 interface under network
https://bugzilla.kernel.org/show_bug.cgi?id=60747

This issue was also reported previously by OLPC and some folks from
the community.

There are 3 network interfaces with different types being created
when mwifiex driver is loaded:

1. mlan0 (infra. STA)
2. uap0 (AP)
3. p2p0 (P2P_CLIENT)

The Network Manager attempts to use all 3 interfaces above without
filtering the managed interface type. As the result, 3 identical
interfaces are displayed under network manager. If user happens to
click on an entry under which its interface is uap0 or p2p0, the
association will fail.

Work around it by removing the creation of AP and P2P interfaces
at driver loading time. These interfaces can be added with 'iw' or
other applications manually when they are needed.
