c815797663 cfg80211: check wdev->netdev in connection work
If a P2P-Device is present and another virtual interface triggers
the connection work, the system crash because it tries to check
if the P2P-Device's netdev (which doesn't exist) is up. Skip any
wdevs that have no netdev to fix this.

6211dd12da mac80211: fix direct probe auth
We send direct probe to broadcast address, as some APs do not respond to
unicast PROBE frames when unassociated. Broadcast frames are not acked,
so we can not use that for trigger MLME state machine, but we need to
use old timeout mechanism.

This fixes authentication timed out like below:

[ 1024.671974] wlan6: authenticate with 54:e6:fc:98:63:fe
[ 1024.694125] wlan6: direct probe to 54:e6:fc:98:63:fe (try 1/3)
[ 1024.695450] wlan6: direct probe to 54:e6:fc:98:63:fe (try 2/3)
[ 1024.700586] wlan6: send auth to 54:e6:fc:98:63:fe (try 3/3)
[ 1024.701441] wlan6: authentication with 54:e6:fc:98:63:fe timed out

With fix, we have:

[ 4524.198978] wlan6: authenticate with 54:e6:fc:98:63:fe
[ 4524.220692] wlan6: direct probe to 54:e6:fc:98:63:fe (try 1/3)

[ 4524.427492] wlan6: RX AssocResp from 54:e6:fc:98:63:fe (capab=0x431 status=0 aid=1)

e248ad3020 cfg80211: fix sending WoWLAN TCP wakeup settings
The code sending the current WoWLAN TCP wakeup settings in
nl80211_send_wowlan_tcp() is not closing the nested attribute,
thus causing the parser to get confused on the receiver side

2430816b4e cfg80211: fix interface down/disconnect state handling
When the interface goes down, there's no need to call
cfg80211_mlme_down() after __cfg80211_disconnect() as
the latter will call the former (if appropriate.)

Also, in __cfg80211_disconnect(), if the cfg80211 SME
isn't used, __cfg80211_disconnected() may still need
to be called (depending on the current state) so that
the SME state gets cleared.

ieee80211_get_tkip_p2k() may be called with interrupts
disabled, so spin_unlock_bh() isn't safe and leads to

3670946fe2 mac80211: fix HT beacon-based channel switch handling
When an HT AP is advertising channel switch in a beacon, it
doesn't (and shouldn't, according to 802.11-2012 Table 8-20)
include a secondary channel offset element. The only possible
interpretation is that the previous secondary channel offset
remains valid, so use that when switching channel based only
on beacon information.

VHT requires the Wide Bandwidth Channel Switch subelement to
be present in the Channel Switch Wrapper element, so the code
for that is probably ok (see 802.11ac Draft 4, 8.4.2.165.)

John W. Linville says:

====================
Here is a batch of fixes intended for the 3.10 stream.

Amitkumar Karwar provides an mwifiex fix to plug a memory leak when
the driver is unloaded.

Bing Zhao brings an mwifiex fix for some flag handling that leads to
log spam and an unusable interface.

Daniel Drake offers an mwifiex fix for multicast filter setup, to
correctly implement wakeup behaviour for multicast WOL.

Felix Fietkau fixes an ath9k problem that produces logspam and keycache
errors due to a bad return code.

Stanislaw Gruszka produces an fix for a WARNING from ath5k, and an
iwl4965 workaround to stop advertising a feature that doesn't work with
the current mac80211 implementation.

Sujith Manoharan gives us an ath9k fix to reprogram the HW beacon timers
after a TSF update, and an initvals fix for the AR9565 device.

Thommy Jakobsson fixes an rx descriptor underrun on b43.

Pull trivial pstore update from Tony Luck:
 "Couple of pstore cleanups"

It turns out that the kmemdup() conversion ends up being undone by the
fact that the memory block also needed the ecc information (see commit
bd08ec33b5: "pstore/ram: Restore ecc information block"), so all that
remains after merging is the error return code change.

 "Support for two new platforms based on ARC700:
   - Abilis TB10x SoC [Chritisian/Pierrick]
   - Simulator only System-C Model [Mischa]

  ARC specific MM improvements:
   - Avoid full TLB flush (ASID increment) on munmap (even single page)
   - VIPT Cache Flushing improvements
     + Delayed dcache flush for non-aliasing dcache (big performance boost)

Pull btrfs update from Chris Mason:
 "These are mostly fixes.  The biggest exceptions are Josef's skinny
  extents and Jan Schmidt's code to rebuild our quota indexes if they
  get out of sync (or you enable quotas on an existing filesystem).

  The skinny extents are off by default because they are a new variation
  on the extent allocation tree format.  btrfstune -x enables them, and
  the new format makes the extent allocation tree about 30% smaller.

  I rebased this a few days ago to rework Dave Sterba's crc checks on
  the super block, but almost all of these go back to rc6, since I
  though 3.9 was due any minute.

  The biggest missing fix is the tracepoint bug that was hit late in
  3.9.  I ran into problems with that in overnight testing and I'm still
  tracking it down.  I'll definitely have that fixed for rc2."

commit 6cd2c7db4 (videomode: videomode_from_timing work) changed the name of

the 'data_flags' field in videomode structure to 'flags'

Adapt to these changes in order to fix the following errors:
