+Subject: ARC: Use correct PTAG register for icache flush
+
+From: Vineet Gupta <vgupta@synopsys.com>
+
+commit b053940df41808f0f27568eb36820d10a8a987f8 upstream.
+
+This fixes a subtle issue with cache flush which could potentially cause
+random userspace crashes because of stale icache lines.
+
+This error crept in when consolidating the cache flush code
+
+Fixes: bd12976c3664 (ARC: cacheflush refactor #3: Unify the {d,i}cache)

+Subject: ath9k: Fix ETSI compliance for AR9462 2.0
+
+From: Sujith Manoharan <c_manoha@qca.qualcomm.com>
+
+commit b3050248c167871ca52cfdb2ce78aa2460249346 upstream.
+
+The minimum CCA power threshold values have to be adjusted
+for existing cards to be in compliance with new regulations.
+Newer cards will make use of the values obtained from EEPROM,
+support for this was added earlier. To make sure that cards
+that are already in use and don't have proper values in EEPROM,
+do not violate regulations, use the initvals instead.

+MIME-Version: 1.0

+
+From: Felix Fietkau <nbd@openwrt.org>
+
+commit b7b146c9c9a0248cc57da71244f672ebc54bbef1 upstream.
+
+Only set sc->rx.discard_next to rx_stats->rs_more when actually
+discarding the current descriptor.
+
+Also, fix a detection of broken descriptors:
+First the code checks if the current descriptor is not done.
+Then it checks if the next descriptor is done.
+Add a check that afterwards checks the first descriptor again, because
+it might have been completed in the mean time.
+
+This fixes a regression introduced in

+Subject: ath9k: fix ps-poll responses under a-mpdu sessions
+
+From: Felix Fietkau <nbd@openwrt.org>
+
+commit 558ff225de80ac95b132d3a115ddadcd64498b4f upstream.
+
+When passing tx frames to the U-APSD queue for powersave poll responses,
+the ath_atx_tid pointer needs to be passed to ath_tx_setup_buffer for
+proper sequence number accounting.
+
+This fixes high latency and connection stability issues with ath9k
+running as AP and a few kinds of mobile phones as client, when PS-Poll
+is heavily used

+
+From: Stanislaw Gruszka <sgruszka@redhat.com>
+
+commit 21f8aaee0c62708654988ce092838aa7df4d25d8 upstream.
+
+We check tid->sched without a lock taken on ath_tx_aggr_sleep(). That
+is race condition which can result of doing list_del(&tid->list) twice
+(second time with poisoned list node) and cause crash like shown below:

+commit 14eedc32a3c0ec9dd70448a73763ee21feae3111 upstream.
+
+Without this, a bo may get created in the cpu-inaccessible vram.
+Before the CP engines get setup, all copies are done via cpu memcpy.
+
+This means that the cpu tries to read from inaccessible memory, fails,
+and the radeon module proceeds to disable acceleration.
+
+Doing this has no downsides, as the real VRAM size gets set as soon as the
+CP engines get init.
+
+This is a candidate for 3.14 fixes.
+
+v2: Add comment on why the function is used

+
+From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
+
+commit 205e2210daa975d92ace485a65a31ccc4077fe1a upstream.
+
+NICs supported by iwldvm don't handle well TX AMPDU.
+Disable it by default, still leave the possibility to
+the user to force enable it with a debug parameter.
+
+NICs supported by iwlmvm don't suffer from the same issue,
+leave TX AMPDU enabled by default for these.

+From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
+
+commit ec6f678c74dbdb06a6a775bbb00f1d26c17c404b upstream.
+
+We set IWL_STA_UCODE_INPROGRESS flag when we add a station
+and clear it when we send the LQ command for it. But the LQ
+command is sent only when the association succeeds.
+If the association doesn't succeed, we would leave this flag
+set and that wouldn't indicate the station entry as vacant.
+
+This probably fixes:

+Subject: iwlwifi: fix TX status for aggregated packets
+
+From: Johannes Berg <johannes.berg@intel.com>
+
+commit 143582c6847cb285b361804c613127c25de60ca4 upstream.
+
+Only the first packet is currently handled correctly, but then
+all others are assumed to have failed which is problematic. Fix
+this, marking them all successful instead (since if they're not
+then the firmware will have transmitted them as single frames.)
+
+This fixes the lost packet reporting.
+
+Also do a tiny variable scoping cleanup.

+From: Max Stepanov <Max.Stepanov@intel.com>
+
+commit e7eb65cac0720df8b3946af7f7a9dc363cf0a814 upstream.
+
+Some APs reject STA association request if a listen interval value exceeds
+a threshold of 10. Thus, for example, Cisco APs may deny STA associations
+returning status code 12 (Association denied due to reason outside the scope
+of 802.11 standard) in the association response frame.
+
+Fixing the issue by setting the default IWL_CONN_MAX_LISTEN_INTERVAL value
+from 70 to 10.

+Subject: mac80211: don't validate unchanged AP bandwidth while tracking
+
+From: Johannes Berg <johannes.berg@intel.com>
+
+commit 963a1852fbac4f75a2d938fa2e734ef1e6d4c044 upstream.
+
+The MLME code in mac80211 must track whether or not the AP changed
+bandwidth, but if there's no change while tracking it shouldn't do
+anything, otherwise regulatory updates can make it impossible to
+connect to certain APs if the regulatory database doesn't match the
+information from the AP. See the precise scenario described in the
+code.
+
+This still leaves some possible problems with CSA or if the AP
+actually changed bandwidth, but those cases are less common and
+won't completely prevent using it.
+
+This fixes https://bugzilla.kernel.org/show_bug.cgi?id=70881

+Subject: mac80211: fix AP powersave TX vs. wakeup race
+
+From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
+
+commit 1d147bfa64293b2723c4fec50922168658e613ba upstream.
+
+There is a race between the TX path and the STA wakeup: while
+a station is sleeping, mac80211 buffers frames until it wakes
+up, then the frames are transmitted. However, the RX and TX
+path are concurrent, so the packet indicating wakeup can be
+processed while a packet is being transmitted.
+
+This can lead to a situation where the buffered frames list
+is emptied on the one side, while a frame is being added on
+the other side, as the station is still seen as sleeping in
+the TX path.
+
+As a result, the newly added frame will not be send anytime
+soon. It might be sent much later (and out of order) when the
+station goes to sleep and wakes up the next time.
+
+Additionally, it can lead to the crash below.
+
+Fix all this by synchronising both paths with a new lock.
+Both path are not fastpath since they handle PS situations.
+
+In a later patch we'll remove the extra skb queue locks to
+reduce locking overhead.

+
+From: Johannes Berg <johannes.berg@intel.com>
+
+commit cb664981607a6b5b3d670ad57bbda893b2528d96 upstream.
+
+When a VHT network uses 20 or 40 MHz as per the HT operation
+information, the channel center frequency segment 0 field in
+the VHT operation information is reserved, so ignore it.
+
+This fixes association with such networks when the AP puts 0
+into the field, previously we'd disconnect due to an invalid
+channel with the message
+wlan0: AP VHT information is invalid, disable VHT

+Subject: mwifiex: do not advertise usb autosuspend support
+
+From: Bing Zhao <bzhao@marvell.com>
+
+commit adb07df1e039e9fe43e66aeea8b4771f83659dbb upstream.
+
+As many Surface Pro I & II users have found out, the mwifiex_usb
+doesn't support usb autosuspend, and it has caused some system
+stability issues.
+
+Bug 69661 - mwifiex_usb on MS Surface Pro 1 is unstable
+Bug 60815 - Interface hangs in mwifiex_usb
+Bug 64111 - mwifiex_usb USB8797 crash failed to get signal
+           information
+
+USB autosuspend get triggered when Surface Pro's AC power is
+removed or powertop enables power saving on USB8797 device.
+Driver's suspend handler is called here, but resume handler
+won't be called until the AC power is put back on or powertop
+disables power saving for USB8797.
+
+We need to refactor the suspend/resume handlers to support
+usb autosuspend properly. For now let's just remove it.

+
+From: Amitkumar Karwar <akarwar@marvell.com>
+
+commit 1c97560f6d751a620978504a4a888c631192b71a upstream.
+
+We are sending sleep confirm done interrupt in the middle of
+sleep handshake. There is a corner case when Tx done interrupt
+is received from firmware during sleep handshake due to which
+host and firmware power states go out of sync causing cmd and
+Tx data timeout problem.
+
+Hence sleep confirm done interrupt is sent at the end of sleep
+handshake to fix the problem.
