iwlwifi: don't print module loading error if not modular
If the opmode modules aren't modular, there's no point in
printing an error message that request_module() failed.
This will happen because the probe runs during iwlwifi's
init and the opmode is only added during its init.
I tried to avoid to send zeroed LQ cmd, but I made a (very)
stupid mistake in the memcmp.
Since this patch has been ported to stable, the fix should
go to stable too.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=58341

Move the counter for non-AMPDU frames to mvm. It is needed
for the drain flow which happens once the ieee80211_sta has
been freed, so keeping it in iwl_mvm_sta which is embed into
ieee80211_sta is not a good idea.
Also, since its purpose it to remove the STA in the fw only
after all the frames for this station have exited the shared
Tx queues, we need to decrement it in the reclaim flow. This
flow can happen after ieee80211_sta has been removed, which
means that we have no iwl_mvm_sta there. So we can't know
what is the vif type. Hence, we know audit these frames for
all the vif types.
In order to avoid spawning sta_drained_wk all the time, we
now check that we are in a flow in which draining might
happen - only when mvmsta is NULL. This is better than
previous code that would spawn sta_drained_wk all the time
in AP mode.

iwlwifi: mvm: Prevent setting assoc flag in MAC_CONTEXT_CMD
In the normal flow first MAC_CONTEXT_CMD for particular interface is
never sent while associated. The exception is fw restart flow when
resuming from suspend when WoWLAN is enabled. In this case successive
"add" and "modify" MAC_CONTEXT_CMD commands may be sent with assoc flag
set what cause FW mal functioning. To prevent this never set assoc flag
in MAC_CONTEXT_CMD with action "add".

A race condition exists when registering the first watchdog device.
Sequence of events:
- watchdog_register_device calls watchdog_dev_register
- watchdog_dev_register creates the watchdog misc device by calling
misc_register.
At that time, the matching character device (/dev/watchdog0) does not yet
exist, and old_wdd is not set either.
- Userspace gets an event and opens /dev/watchdog
- watchdog_open is called and sets wdd = old_wdd, which is still NULL,
and tries to dereference it. This causes the kernel to panic.
Seen with systemd trying to open /dev/watchdog immediately after
it was created.

If DEBUG_LL and earlyprintk are enabled, and omap-serial.c is compiled

The problem is a race between the late_initcall for omap_device (which
idles devices that have no drivers) and the late_initcall in
kernel/printk.c which turns off the earlyconsole. Any printks
that happen between this omap_device late initcall and the earlyconsole

communication to the panel driver (spi1.2) fails unless the touchscreen

ARM: dts: OMAP4: Fix ethernet IRQ for OMAP4 boards
Commit ff5c9059 (ARM: dts: OMAP3+: Correct gpio #interrupts-cells
property) updated the number of interrupt cells required for configuring
gpios as interrupts for other devices (such as ethernet controllers).
This update allowed the interrupt type (edge, level, etc) to be
configured via device-tree (as described in the
Documentation/devicetree/bindings/gpio/gpio-omap.txt).
This broke ethernet support on the OMAP4 SDP board that defines a gpio
as the ethernet IRQ because the interrupt type (level, edge, etc) was
not getting configured correctly. This board use the ks8851 ethernet
chip which has an active low interrupt. Fix this by defining the gpio
interrupt as active-low in the device-tree binding.
Please note that the OMAP4-VAR-SOM also uses the same ethernet
controller and it is expected it will have the same problem. So the
same fix is also applied to this board.

mm/slab: Fix crash during slab init
Commit 8a965b3baa89 ("mm, slab_common: Fix bootstrap creation of kmalloc
caches") introduced a regression that caused us to crash early during
boot. The commit was introducing ordering of slab creation, making sure
two odd-sized slabs were created after specific powers of two sizes.
But, if any of the power of two slabs were created earlier during boot,
slabs at index 1 or 2 might not get created at all. This patch makes
sure none of the slabs get skipped.
Tony Lindgren bisected this down to the offending commit, which really
helped because bisect kept bringing me to almost but not quite this one.

NFS4.1 Fix data server connection race
Unlike meta data server mounts which support multiple mount points to
the same server via struct nfs_server, data servers support a single connection.
Concurrent calls to setup the data server connection can race where the first
call allocates the nfs_client struct, and before the cache struct nfs_client
pointer can be set, a second call also tries to setup the connection, finds the
already allocated nfs_client, bumps the reference count, re-initializes the
session,etc. This results in a hanging data server session after umount.

mwifiex: fix setting of multicast filter
A small bug in this code was causing the ALLMULTI filter to be set
when in fact we were just wanting to program a selective multicast list
to the hardware.
Fix that bug and remove a redundant if condition in the code that
follows.
This fixes wakeup behaviour when multicast WOL is enabled. Previously,
all multicast packets would wake up the system. Now, only those that the
host intended to receive trigger wakeups.

After unregister_netdevice() call the request is queued and
reg_state is changed to NETREG_UNREGISTERING.
As we check for NETREG_UNREGISTERED state, free_netdev() never
gets executed causing memory leak.
Initialize "dev->destructor" to free_netdev() to free device
data after unregistration.

mwifiex: clear is_suspended flag when interrupt is received early
When the XO-4 with 8787 wireless is woken up due to wake-on-WLAN

This can be readily reproduced when putting the XO-4 in a loop where
it goes to sleep due to inactivity, but then wakes up due to an
incoming ping. The error is hit within an hour or two.
This issue happens when an interrupt comes in early while host sleep
is still activated. Driver handles this case by auto cancelling host
sleep. However is_suspended flag is still set which prevents any cmd
or data from being sent to firmware. Fix it by clearing is_suspended
flag in this path.

iwl4965: workaround connection regression on passive channel
Jake reported that since commit 1672c0e31917f49d31d30d79067103432bc20cc7
"mac80211: start auth/assoc timeout on frame status", he is unable to
connect to his AP, which is configured to use passive channel.
After switch to passive channel 4965 firmware drops any TX packet until
it receives beacon. Before commit 1672c0e3 we waited on channel and
retransmit packet after 200ms, that makes we receive beacon on the
meantime and association process succeed. New mac80211 behaviour cause
that any ASSOC frame fail immediately on iwl4965 and we can not
associate.
This patch restore old mac80211 behaviour for iwl4965, by removing
IEEE80211_HW_REPORTS_TX_ACK_STATUS feature. This feature will be
added again to iwl4965 driver, when different, more complex
workaround for this firmware issue, will be added to the driver.
Add handling of rx descriptor underflow. This fixes a fault that could
happen on slow machines, where data is received faster than the CPU can
handle. In such a case the device will use up all rx descriptors and
refuse to send any more data before confirming that it is ok. This
patch enables necessary interrupt to discover such a situation and will
handle them by dropping everything in the ring buffer.
