When a CAC is running and stop_ap is called (e.g. when hostapd is killed
while performing CAC), the CAC must be aborted immediately.
Otherwise ieee80211_stop_ap() will try to stop it when it's too late -
wdev->channel is already NULL and the abort event can not be generated.

There are some APs, notably 2G/3G/4G Wifi routers, specifically the
"Onda PN51T", "Vodafone PocketWiFi 2", "ZTE MF60" and a similar
T-Mobile branded device [1] that erroneously don't include all the
needed information in (re)association response frames. Work around
this by assuming the information is the same as it was in the
beacon or probe response and using the data from there instead.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=58881.
[1] https://bbs.archlinux.org/viewtopic.php?pid=1277305
Note that this requires marking the first ieee802_11_parse_elems()
argument const, otherwise we'd get a compiler warning.

When changing the MAC address of a single vif mac80211 will check if
the new address fits into the address mask specified by the driver.
This only needs to be done when using multiple BSSIDs. Hence, check
the new address only against all other vifs.
Also fix the MAC address assignment on new interfaces if the user
changed the address of a vif such that perm_addr is not covered by
addr_mask anymore.

Since Eric's commit efe117ab8 ("Speedup ieee80211_remove_interfaces")
there's a bug in mac80211 when it unregisters with AP_VLAN interfaces
up. If the AP_VLAN interface was registered after the AP it belongs
to (which is the typical case) and then we get into this code path,
unregister_netdevice_many() will crash because it isn't prepared to
deal with interfaces being closed in the middle of it. Exactly this
happens though, because we iterate the list, find the AP master this
AP_VLAN belongs to and dev_close() the dependent VLANs. After this,
unregister_netdevice_many() won't pick up the fact that the AP_VLAN
is already down and will do it again, causing a crash.

A lot of code in mac80211 assumes that the hw queues are
set up correctly for all interfaces (except for monitor)
but this isn't true for AP_VLAN interfaces. Fix this by
copying the AP master configuration when an AP VLAN is
brought up, after this the AP interface can't change its
configuration any more and needs to be brought down to
change it, which also forces AP_VLAN interfaces down, so
just copying in open() is sufficient.

The code I added in "mac80211: don't start new netdev queues
if driver stopped" crashes for monitor and AP VLAN interfaces
because while they have a netdev, they don't have queues set
up by the driver.
To fix the crash, exclude these from queue accounting here
and just start their netdev queues unconditionally.
For monitor, this is the best we can do, as we can redirect
frames there to any other interface and don't know which one
that will since it can be different for each frame.
For AP VLAN interfaces, we can do better later and actually
properly track the queue status. Not doing this is really a
separate bug though.

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.

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)

[ 1024.701441] wlan6: authentication with 54:e6:fc:98:63:fe timed out

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.

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.)

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
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 function from videomode_from_timing() to videomode_from_timings().
commit 32ed6ef1 (videomode: create enum for videomode's display flags) changed
the 'data_flags' field in videomode structure to 'flags'
Adapt to these changes in order to fix the following errors:
drivers/video/mxsfb.c:761:3: error: too many arguments to function 'videomode_from_timing'
drivers/video/mxsfb.c:761:7: error: void value not ignored as it ought to be

drivers/video/mxsfb.c:770:9: error: 'struct videomode' has no member named 'data_flags'
Also, select VIDEOMODE_HELPER instead of OF_VIDEOMODE, as this one is
deprecated.
