Rajkumar Manoharan 1fe860edb0 ath9k_hw: start noisefloor calibration after MCI reset
noisefloor calibration has to be loaded and started after
chip reset completion and restoring chainmask. Right now it is
being started before MCI reset completion on full reset. Fix that.

Hauke Mehrtens 6270d1c39c bcma: remove chip ids doing nothing from PMU initialization.
The list of devices where nothing has to be done in
bcma_pmu_resources_init() and bcma_pmu_workarounds() is longer as all
the SoCs are missing there and some new devices will be added in some
time later. This patch changes the default case to just log on debug
level and also let the other devices which do not need any special
handling into the default case, instead of adding the missing 8 SoC
chip ids.

Hauke Mehrtens e84a38eac8 bcma: remove bcma_pmu_{pll,swreg}_init()
These functions are doing nothing in the current code.

I do not think we will need these function in the future as the
corresponding functions in the Broadcom SDK are just doing something
useful on chips supported by ssb or fullmac chips.

There is not core id with 0x4329, but at the same place in the open
source part of the Broadcom SDK is a check for some device with the
chip id of 0x4329. The device with a chip id of 0x4329 is a full mac
device, so it will never be supported by bcma, this part is running in
the firmware of the device and not on the host CPU.

Emmanuel Grumbach b48d966526 iwlegacy: don't mess up the SCD when removing a key
When we remove a key, we put a key index which was supposed
to tell the fw that we are actually removing the key. But
instead the fw took that index as a valid index and messed
up the SRAM of the device.

This memory corruption on the device mangled the data of
the SCD. The impact on the user is that SCD queue 2 got
stuck after having removed keys.

    iwlwifi: always monitor for stuck queues

    If we only monitor while associated, the following
    can happen:
     - we're associated, and the queue stuck check
       runs, setting the queue "touch" time to X
     - we disassociate, stopping the monitoring,
       which leaves the time set to X
     - almost 2s later, we associate, and enqueue
       a frame
     - before the frame is transmitted, we monitor
       for stuck queues, and find the time set to
       X, although it is now later than X + 2000ms,
       so we decide that the queue is stuck and
       erroneously restart the device

Stanislaw Gruszka efd821182c rt2x00usb: fix indexes ordering on RX queue kick
On rt2x00_dmastart() we increase index specified by Q_INDEX and on
rt2x00_dmadone() we increase index specified by Q_INDEX_DONE. So entries
between Q_INDEX_DONE and Q_INDEX are those we currently process in the
hardware. Entries between Q_INDEX and Q_INDEX_DONE are those we can
submit to the hardware.

According to that fix rt2x00usb_kick_queue(), as we need to submit RX
entries that are not processed by the hardware. It worked before only
for empty queue, otherwise was broken.

Note that for TX queues indexes ordering are ok. We need to kick entries
that have filled skb, but was not submitted to the hardware, i.e.
started from Q_INDEX_DONE and have ENTRY_DATA_PENDING bit set.

From practical standpoint this fixes RX queue stall, usually reproducible
in AP mode, like for example reported here:

Eliad Peller 10a9109f27 mac80211: destroy assoc_data correctly if assoc fails
If association failed due to internal error (e.g. no
supported rates IE), we call ieee80211_destroy_assoc_data()
with assoc=true, while we actually reject the association.

This results in the BSSID not being zeroed out.

After passing assoc=false, we no longer have to call
sta_info_destroy_addr() explicitly. While on it, move
the "associated" message after the assoc_success check.

Gao feng b761c9b1f4 cgroup: fix panic in netprio_cgroup
we set max_prioidx to the first zero bit index of prioidx_map in
function get_prioidx.

So when we delete the low index netprio cgroup and adding a new
netprio cgroup again,the max_prioidx will be set to the low index.

when we set the high index cgroup's net_prio.ifpriomap,the function
write_priomap will call update_netdev_tables to alloc memory which
size is sizeof(struct netprio_map) + sizeof(u32) * (max_prioidx + 1),
so the size of array that map->priomap point to is max_prioidx +1,
which is low than what we actually need.

fix this by adding check in get_prioidx,only set max_prioidx when
max_prioidx low than the new prioidx.

David Daney b93984c9af netdev/phy: Fixup lockdep warnings in mdio-mux.c
With lockdep enabled we get:

=============================================
[ INFO: possible recursive locking detected ]
3.4.4-Cavium-Octeon+ #313 Not tainted
---------------------------------------------
kworker/u:1/36 is trying to acquire lock:
(&bus->mdio_lock){+.+...}, at: [<ffffffff813da7e8>] mdio_mux_read+0x38/0xa0

but task is already holding lock:
 (&bus->mdio_lock){+.+...}, at: [<ffffffff813d79e4>] mdiobus_read+0x44/0x88

other info that might help us debug this:
 Possible unsafe locking scenario:

       CPU0
       ----
  lock(&bus->mdio_lock);
  lock(&bus->mdio_lock);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
.
.
.

This is a false positive, since we are indeed using 'nested' locking,
we need to use mutex_lock_nested().

Now in theory we can stack multiple MDIO multiplexers, but that would
require passing the nesting level (which is difficult to know) to
mutex_lock_nested().  Instead we assume the simple case of a single
level of nesting.  Since these are only warning messages, it isn't so
important to solve the general case.

Alexander Duyck d4e4164943 ixgbe: DCB and SR-IOV can not co-exist and will cause hangs
DCB and SR-IOV cannot currently be enabled at the same time as the queueing
schemes are incompatible.  If they are both enabled it will result in Tx
hangs since only the first Tx queue will be able to transmit any traffic.

This simple fix for this is to block us from enabling TCs in ixgbe_setup_tc
if SR-IOV is enabled.  This change will be reverted once we can support
SR-IOV and DCB coexistence.

Eric Dumazet 960fb66e52 netem: add limitation to reordered packets
Fix two netem bugs :

1) When a frame was dropped by tfifo_enqueue(), drop counter
   was incremented twice.

2) When reordering is triggered, we enqueue a packet without
   checking queue limit. This can OOM pretty fast when this
   is repeated enough, since skbs are orphaned, no socket limit
   can help in this situation.

Neil Horman ed10627725 sctp: refactor sctp_packet_append_chunk and clenup some memory leaks
While doing some recent work on sctp sack bundling I noted that
sctp_packet_append_chunk was pretty inefficient.  Specifially, it was called
recursively while trying to bundle auth and sack chunks.  Because of that we
call sctp_packet_bundle_sack and sctp_packet_bundle_auth a total of 4 times for
every call to sctp_packet_append_chunk, knowing that at least 3 of those calls
will do nothing.

So lets refactor sctp_packet_bundle_auth to have an outer part that does the
attempted bundling, and an inner part that just does the chunk appends.  This
saves us several calls per iteration that we just don't need.

Also, noticed that the auth and sack bundling fail to free the chunks they
allocate if the append fails, so make sure we add that in

Eric Dumazet acfa9e94e2 net: dont use __netdev_alloc_skb for bounce buffer
commit a1c7fff7e1 (net: netdev_alloc_skb() use build_skb()) broke b44 on
some 64bit machines.

It appears b44 and b43 use __netdev_alloc_skb() instead of alloc_skb()
for their bounce buffers.

There is no need to add an extra NET_SKB_PAD reservation for bounce
buffers :

- In TX path, NET_SKB_PAD is useless

- In RX path in b44, we force a copy of incoming frames if
  GFP_DMA allocations were needed.
