If a server side socket is bound to an address, but not in the listening
state yet, incoming connection requests should receive a reset control
packet in response. However, the function used to send the reset
silently drops the reset packet if the sending socket isn't bound
to a remote address (as is the case for a bound socket not yet in
the listening state). This change fixes this by using the src
of the incoming packet as destination for the reset packet in
this case.

mlxsw: VXLAN and firmware flashing fixes
Patch #1 fixes firmware flashing failures by increasing the time period
after which the driver fails the transaction with the firmware. The
problem is explained in detail in the commit message.
Patch #2 adds a missing trap for decapsulated ARP packets. It is
necessary for VXLAN routing to work.
Patch #3 fixes a memory leak during driver reload caused by NULLing a
pointer before kfree().

After a packet was decapsulated it is classified to the relevant FID
based on its VNI and undergoes L2 forwarding.
Unlike regular (non-encapsulated) ARP packets, Spectrum does not trap
decapsulated ARP packets during L2 forwarding and instead can only trap
such packets in the underlay router during decapsulation.
Add this missing packet trap, which is required for VXLAN routing when
the MAC of the target host is not known.

During the firmware flash process, some of the EMADs get timed out, which
causes the driver to send them again with a limit of 5 retries. There are
some situations in which 5 retries is not enough and the EMAD access fails.
If the failed EMAD was related to the flashing process, the driver fails
the flashing.
The reason for these timeouts during firmware flashing is cache misses in
the CPU running the firmware. In case the CPU needs to fetch instructions
from the flash when a firmware is flashed, it needs to wait for the
flashing to complete. Since flashing takes time, it is possible for pending
EMADs to timeout.
Fix by increasing EMADs' timeout while flashing firmware.

When the socket is closed, we need to call xprt_disconnect_done() in order
to clean up the XPRT_WRITE_SPACE flag, and wake up the sleeping tasks.
However, we also want to ensure that we don't wake them up before the socket
is closed, since that would cause thundering herd issues with everyone
piling up to retransmit before the TCP shutdown dance has completed.
Only the task that holds XPRT_LOCKED needs to wake up early in order to
allow the close to complete.

ASoC: Updates for v4.21
Not much work on the core this time around but we've seen quite a bit of
driver work, including on the generic DT drivers. There's also a large
part of the diff from a merge of the DaVinci and OMAP directories, along
with some active development there:
- Preparatory work from Morimoto-san for merging the audio-graph and
audio-graph-scu cards.
- A merge of the TI OMAP and DaVinci directories, the OMAP product line
has been merged into the DaVinci product line so there is now a lot
of IP sharing which meant that the split directories just got in the
way. This has pulled in a few architecture changes as well.
- A big cleanup of the Maxim MAX9867 driver from Ladislav Michl.
- Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
controllers.

Andy spotted a regression in the fs/gs base helpers after the patch series
was committed. The helper functions which write fs/gs base are not just
writing the base, they are also changing the index. That's wrong and needs
to be separated because writing the base has not to modify the index.
While the regression is not causing any harm right now because the only
caller depends on that behaviour, it's a guarantee for subtle breakage down
the road.
Make the index explicitly changed from the caller, instead of including
the code in the helpers.
Subsequently, the task write helpers do not handle for the current task
anymore. The range check for a base value is also factored out, to minimize
code redundancy from the caller.

Create new directory to contain all Texas Instruments specific DAI,
platform and machine drivers instead of scattering them under davinci and
omap directories.
There is already inter dependency between the two directories becasue of
McASP (on dra7x it is serviced by sDMA, not EDMA).
With the upcoming AM654 we will need to introduce new platform driver for
UDMA and it does not fit under davinci, nor under omap.
With the move I have restructured the Kconfig to be more usable in the era
of simple-sound-card:
CPU DAIs can be selected individually and they will select the platform
driver they can be served with.
To avoid breakage, I have moved over deprecated Kconfig options so
defconfig builds will work without regression.

Recently TXQ teardown was moved earlier in ieee80211_unregister_hw(),
to avoid a use-after-free of the netdev data. However, interfaces
aren't fully removed at the point, and cfg80211_shutdown_all_interfaces
can for example, TX a deauth frame. Move the TXQ teardown to the
point between cfg80211_shutdown_all_interfaces and the free of
netdev queues, so we can be sure they are torn down before netdev
is freed, but after there is no ongoing TX.

There are systems in which non-wakeup GPEs fire during the "noirq"
suspend stage of suspending devices and that effectively prevents the
system that tries to suspend to idle from entering any low-power
state at all. If the offending GPE fires regularly and often enough,
the system appears to be suspended, but in fact it is in a tight loop
over "noirq" suspend and "noirq" resume of devices all the time.
To prevent that from happening, disable all non-wakeup GPEs except
for the EC GPE for suspend-to-idle (the EC GPE is special, because
on some systems it has to be enabled for power button wakeup events
to be generated as expected).

The code uses a bitmap to check for duplicate tokens during parsing, and
that doesn't work at all for the negative Opt_err token case.
There is absolutely no reason to make Opt_err be negative, and in fact
it only confuses things, since some of the affected functions actually
return a positive Opt_xyz enum _or_ a regular negative error code (eg
-EINVAL), and using -1 for Opt_err makes no sense.
There are similar problems in ima_policy.c and key encryption, but they
don't have the immediate bug wrt bitmap handing, and ima_policy.c in
particular needs a different patch to make the enum values match the
token array index. Mimi is sending that separately.

Address a few false positive compiler warnings related to uninitialised
variables. While at it, use bool where bool is needed and %u to print an
unsigned integer.

This patch adds support to run dual pipes simultaneously.
A private ioctl to configure the pipe mode (video or still)
is also implemented.
IPU3 hardware supports a maximum of 2 streams per pipe.
With the support of dual pipes, more than 2 stream outputs
can be achieved.
This helps to support advanced camera features like
Continuous View Finder (CVF) and Snapshot During Video(SDV).
Extend ipu3 IMGU driver to support dual pipes
1. Extend current IMGU device to contain 2 groups
of video nodes and 2 subdevs
2. Extend current css to support 2 pipeline and make
CSS APIs to support 2 pipe
3. Add a v4l2 ctrl to allow user to specify the mode
of the pipe
4. Check media pipeline link status to get enabled
pipes

There is a smatch warning:
drivers/media/dvb-frontends/drxk_hard.c: drivers/media/dvb-frontends/drxk_hard.c:1478 scu_command() error: we previously assumed 'parameter' could be null (see line 1467)
Telling that parameter might be NULL. Well, it can't, due to the
way the driver works, but it doesn't hurt to add a check, in order
to shut up smatch.
