John W. Linville says:
====================
Please pull this batch of fixes intended for the 3.10 stream...
Regarding the NFC bits, Samuel says:
"This is the first batch of NFC fixes for 3.10, and it contains:
- 3 fixes for the NFC MEI support:
* We now depend on the correct Kconfig symbol.
* We register an MEI event callback whenever we enable an NFC device,
otherwise we fail to read anything after an enable/disable cycle.
* We only disable an MEI device from its disable mey_phy_ops,
preventing useless consecutive disable calls.
- An NFC Makefile cleanup, as I forgot to remove a commented out line when
moving the LLCP code to the NFC top level directory."
As for the mac80211 bits, Johannes says:
"This time I have a fix from Stanislaw for a stupid mistake I made in the
auth/assoc timeout changes, a fix from Felix for 64-bit traffic counters
and one from Helmut for address mask handling in mac80211. I also have a
few fixes myself for four different crashes reported by a few people."
And Johannes says this about the iwlwifi bit:
"This fixes a brown paper-bag bug that we really should've caught in
review. More details in the changelog for the fix."
On top of that...
Arend van Spriel and Hante Meuleman cooperate to send a series of AP
and P2P mode fixes for brcmfmac.
Gabor Juhos corrects a register offset for AR9550, avoiding a bus
error.
Dan Carpenter provides a fixup to some dmesg output in the atmel
driver.
And, finally...
Felix Fietkau not only gives us a trio of small AR934x fixes, but
also refactors the ath9k aggregation session start/stop handling
(using the generic mac80211 support) in order to avoid a deadlock.
Please let me know if there are problems!

During a PCI EEH/AER error recovery flow, if the device did not successfully
restart, the error_detected() hook may be called a second time with a
"perm_failure" state. This patch skips over driver cleanup for the second
invocation of the callback.
Also, Lancer error recovery code is fixed-up to handle these changes.

We currently allow changing the mq flag (IFF_MULTI_QUEUE) for a persistent
device. This will result a mismatch between the number the queues in netdev and
tuntap. This is because we only allocate a 1q netdevice when IFF_MULTI_QUEUE was
not specified, so when we set the IFF_MULTI_QUEUE and try to attach more queues
later, netif_set_real_num_tx_queues() may fail which result a single queue
netdevice with multiple sockets attached.
Solve this by disallowing changing the mq flag for persistent device.
Bug was introduced by commit edfb6a148ce62e5e19354a1dcd9a34e00815c2a1
(tuntap: reduce memory using of queues).

In function be_get_nic_desc(), it will go through the descriptor array
returned from f/w. By comparing the desc_type field, it determines whether
there is a nic descriptor in the array or not. In the case of no nic
descriptor, this function should return NULL.
The code may return an invalide descriptor, when there is no nic descriptor
in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case,
even there is no nic descriptor, it will still return the lase descriptor
since the i doesn't equal to MAX_RESOURCE_DESC.
This patch fix this issue by returning the descriptor when find it and return
NULL for other cases.

After resetting the device, the driver waits for a signature to be
updated to know that firmware has completed initialization. However, the
call to tg3_poll_fw() is being done too late and we're writing to the
GRC_MODE register before it has completely initialized, causing
contention with firmware. This logic has existed since day one but is
causing PCIE link to go down randomly at startup on one platform once
every few hundred reboots.
Move the tg3_poll_fw() up to before we write to the GRC_MODE register
after reset.

Waiting for all subframes of an existing aggregation session to drain
before allowing mac80211 to start a new one is fragile and deadlocks
caused by this behavior have been observed.
Since mac80211 has proper synchronization for aggregation session
start/stop handling, a better approach to session handling is to simply
allow mac80211 to start a new session at any time. This requires
changing the code to discard any packets outside of the BlockAck window
in the A-MPDU software retry code.
This patch implements the above and also simplifies the code.

"This is what I have:
* a patch from Felix to fix RCU usage in his rate table code
* a patch from Ilan to add the wdev id to some notifications so they can
actually be used by userspace
* Sasha Levin found an issue in how hwsim handles devices
* a fix for a bug in the wiphy_register() error path that's been there forever
* three fixes for WoWLAN
* AP mode frame matching was erroneously giving frames to all virtual AP
interfaces (reported by Jouni)
* a fix for HT handling in my CSA changes, found by Sujith
* a fix for some locking simplifications gone wrong
* Ben Greear found more cfg80211/mac80211 state confusion
* and a fix for another bug found by Jouni: local state changes need to be
reported by mac80211 to cfg80211 so it disconnects properly."
And for the iwlwifi bits, he says:
"I have fixes for a firmware crash during resume, multicast RX,
aggregation and a workaround for a firmware scanning bug."
Along with those...
Albert Pool adds a USB ID to the rtl8192cu driver.
Arend van Spriel restores a driver option support flag that had been
removed from 3.9 due to a bug in that version of the driver.
Felix Fietkau fixes a trio of ath9k issues with a series of small
patches.
Geert Uytterhoeven provides a Kconfig fix for ath9k (which you also
merged, so it isn't in the diff here).
Larry Finger gives us a fix for a build warning on big-endian systems
for rtlwifi.
Rafał Miłecki adds some core IDs to the bcma driver.
Sujith Manoharan fixes a module unloading crash in ath9k, and corrects
some calibration settings for AR9485.

This patch fixes a potential race with concurrently running asynchronous
write requests. The values for device's RX control register are now
stored in dynamically allocated buffers so each URB submission has it's
own copy. Doing it the old way is data clobbering prone.
This patch is against latest 'net' tree.

Starting with commit 91226790bbe2dbfbba48dd79d49f2b38ef10eb97
`bnx2x: use FW 7.8.17', the bnx2x driver no longer requests the FW to perform
IP checksums for IPv4 packets.
This behaviour needs to be revised for 57710/57711 chips -
when using GSO, if the driver will not set the IP checksum flag then packets
will be transmitted by the chip without a valid IP checksum, resulting in
a drop of all such packets on the receiver-side.

8168evl offloaded checksums are wrong since commit
e5195c1f31f399289347e043d6abf3ffa80f0005 ("r8169: fix 8168evl frame padding.")
pads small packets to 60 bytes (without ethernet checksum). Typical symptoms
appear as UDP checksums which are wrong by the count of added bytes.
It isn't worth compensating. Let the driver checksum.
Due to the skb length changes, TSO code is moved before the Tx descriptor gets
written.

When bond_3ad_get_active_agg_info() is used in all show_ad_ functions
it is not protected against slave manipulation and since it walks over
the slaves and uses them, this can easily result in NULL pointer
dereference or use of freed memory. Both the new wrapper and the
internal function are exported to the bonding as they're needed in
different places.

When getting arp_ip_targets if we encounter a bad IP, arp_ip_count still
gets increased and all the targets after the wrong one will not be probed
if arp_interval is enabled after that (unless a new IP target is added
through sysfs) because of the zero entry, in this case reading
arp_ip_target through sysfs will show valid targets even if there's a
zero entry.
Example: 1.2.3.4,4.5.6.7,blah,5.6.7.8
When retrieving the list from arp_ip_target the output would be:
1.2.3.4,4.5.6.7,5.6.7.8
but there will be a 0 entry between 4.5.6.7 and 5.6.7.8. If arp_interval
is enabled after that 5.6.7.8 will never be checked because of that.

Changing the mode without any locking can result in multiple races (e.g.
upping a bond, enslaving/releasing). Depending on which race is hit the
impact can vary from incosistent bond state to kernel crash.
Use RTNL to synchronize the mode setting with the dangerous races.

Pull devm usage cleanup from Wolfram Sang:
"Lately, I have been experimenting how to improve the devm interface to
make writing device drivers easier and less error prone while also
getting rid of its subtle issues. I think it has more potential but
still needs work and definately conistency, especiall in its usage.
The first thing I come up with is a low hanging fruit regarding
devm_ioremap_resouce(). This function already checks if the passed
resource is valid and gives an error message if not. So, we can
remove similar checks from the drivers and get rid of a bit of code
and a number of inconsistent error strings.
This series only removes the unneeded check iff devm_ioremap_resource
follows platform_get_resource directly. The previous version tried to
shuffle code if needed, too, what lead to an embarrasing bug. It
turned out to me that shuffling code for all cases found will make the
automated script too complex, so I am unsure if an automated cleanup
is the proper tool for this case. Removing the easy stuff seems
worthwhile to me, though.
Despite various architectures and platform dependencies, I managed to
compile test 45 out of 57 modified files locally using heuristics and
defconfigs."
