On shutdown the driver core calls the bus' shutdown callback also for
unbound devices. A driver's shutdown callback however is only called for
devices bound to this driver. Commit 9c30921fe799 ("driver core:
platform: use bus_type functions") changed the platform bus from driver
callbacks to bus callbacks, so the shutdown function must be prepared to
be called without a driver. Add the corresponding check in the shutdown
function.

According to the X.25 documentation, there was a plan to implement
X.25-over-802.2-LLC. It never finished but left various code stubs in the
X.25 code. At this time it is unlikely that it would ever finish so it
may be better to remove those code stubs.
Also change the documentation to make it clear that this is not a ongoing
plan anymore. Change words like "will" to "could", "would", etc.

On a few of our systems, I found frequent 'unshare(CLONE_NEWNET)' calls
make the number of active slab objects including 'sock_inode_cache' type
rapidly and continuously increase. As a result, memory pressure occurs.
In more detail, I made an artificial reproducer that resembles the
workload that we found the problem and reproduce the problem faster. It
merely repeats 'unshare(CLONE_NEWNET)' 50,000 times in a loop. It takes
about 2 minutes. On 40 CPU cores / 70GB DRAM machine, the available
memory continuously reduced in a fast speed (about 120MB per second,
15GB in total within the 2 minutes). Note that the issue don't
reproduce on every machine. On my 6 CPU cores machine, the problem
didn't reproduce.
'cleanup_net()' and 'fqdir_work_fn()' are functions that deallocate the
relevant memory objects. They are asynchronously invoked by the work
queues and internally use 'rcu_barrier()' to ensure safe destructions.
'cleanup_net()' works in a batched maneer in a single thread worker,
while 'fqdir_work_fn()' works for each 'fqdir_exit()' call in the
'system_wq'. Therefore, 'fqdir_work_fn()' called frequently under the
workload and made the contention for 'rcu_barrier()' high. In more
detail, the global mutex, 'rcu_state.barrier_mutex' became the
bottleneck.
This commit avoids such contention by doing the 'rcu_barrier()' and
subsequent lightweight works in a batched manner, as similar to that of
'cleanup_net()'. The fqdir hashtable destruction, which is done before
the 'rcu_barrier()', is still allowed to run in parallel for fast
processing, but this commit makes it to use a dedicated work queue
instead of the 'system_wq', to make sure that the number of threads is
bounded.

This patch adds three new netlink attributes to encapsulate a list of
expressions per set elements:
- NFTA_SET_EXPRESSIONS: this attribute provides the set definition in
terms of expressions. New set elements get attached the list of
expressions that is specified by this new netlink attribute.
- NFTA_SET_ELEM_EXPRESSIONS: this attribute allows users to restore (or
initialize) the stateful information of set elements when adding an
element to the set.
- NFTA_DYNSET_EXPRESSIONS: this attribute specifies the list of
expressions that the set element gets when it is inserted from the
packet path.

SB Temperature Sensor Interface (SB-TSI) is an SMBus compatible
interface that reports AMD SoC's Ttcl (normalized temperature),
and resembles a typical 8-pin remote temperature sensor's I2C interface
to BMC.
This commit adds basic support using this interface to read CPU
temperature, and read/write high/low CPU temp thresholds.
To instantiate this driver on an AMD CPU with SB-TSI
support, the i2c bus number would be the bus connected from the board
management controller (BMC) to the CPU. The i2c address is specified in
Section 6.3.1 of the spec [1]: The SB-TSI address is normally 98h for
socket 0 and 90h for socket 1, but it could vary based on hardware address
select pins.
[1]: https://www.amd.com/system/files/TechDocs/56255_OSRR.pdf

temp1_max/min.

Commit
7705dc855797 ("x86/vmlinux: Use INT3 instead of NOP for linker fill bytes")
changed the padding bytes between functions from NOP to INT3. However,
when optprobe decodes a target function it finds INT3 and gives up the
jump optimization.
Instead of giving up any INT3 detection, check whether the rest of the
bytes to the end of the function are INT3. If all of them are INT3,
those come from the linker. In that case, continue the optprobe jump
optimization.

We have a problem if we use gpio-keys and configure wakeups such that
we only want one edge to wake us up. AKA:
wakeup-event-action = <EV_ACT_DEASSERTED>;
wakeup-source;
Specifically we end up with a phantom interrupt that blocks suspend if
the line was already high and we want wakeups on rising edges (AKA we
want the GPIO to go low and then high again before we wake up). The
opposite is also problematic.
Specifically, here's what's happening today:
1. Normally, gpio-keys configures to look for both edges. Due to the
current workaround introduced in commit c3c0c2e18d94 ("pinctrl:
qcom: Handle broken/missing PDC dual edge IRQs on sc7180"), if the
line was high we'd configure for falling edges.
2. At suspend time, we change to look for rising edges.
3. After qcom_pdc_gic_set_type() runs, we get a phantom interrupt.
We can solve this by just clearing the phantom interrupt.
NOTE: it is possible that this could cause problems for a client with
very specific needs, but there's not much we can do with this
hardware. As an example, let's say the interrupt signal is currently
high and the client is looking for falling edges. The client now
changes to look for rising edges. The client could possibly expect
that if the line has a short pulse low (and back high) that it would
always be detected. Specifically no matter when the pulse happened,
it should either have tripped the (old) falling edge trigger or the
(new) rising edge trigger. We will simply not trip it. We could
narrow down the race a bit by polling our parent before changing
types, but no matter what we do there will still be a period of time
where we can't tell the difference between a real transition (or more
than one transition) and the phantom.

Currently, the set infrastucture allows for one single expressions per
element. This patch extends the existing infrastructure to allow for up
to two expressions. This is not updating the netlink API yet, this is
coming as an initial preparation patch.

DESTROY events do not include the remaining timeout.
Add the timeout if the entry was removed explicitly. This can happen
when a conntrack gets deleted prematurely, e.g. due to a tcp reset,
module removal, netdev notifier (nat/masquerade device went down),
ctnetlink and so on.
Add the protocol state too for the destroy message to check for abnormal
state on connection termination.
Joint work with Pablo.

ath.git patches for v5.11. Major changes:
ath11k
* suspend support for QCA6390 PCI devices
* support TXOP duration based RTS threshold
* mesh: add support for 256 bitmap in blockack frames in 11ax
|

Now that all the needed pieces are in place implement suspend support QCA6390
PCI devices. All other devices will return -EOPNOTSUPP during suspend. The
suspend is implemented by switching the firmware to WoW mode during suspend, so
the firmware will be running on low power mode while host is in suspend.
At the moment we are not able to shutdown and fully power off the device due to
bugs in MHI subsystem, so WoW mode is a workaround for the time being.
During suspend we enable WoW mode, disable CE irq and DP irq, then put MHI to
suspend state. During resume, driver resumes MHI firstly, then enables CE irq
and dp IRQ, and sends WoW wakeup command to firmware.

Firmware will check all the pipes before entering WoW mode during suspend. If
ATH11K_HTC_FLAG_NEED_CREDIT_UPDATE is set, firmware treats this pipe needed to
return credit even though it's actually not required. If any pipe needs to
return credit, the suspend_complete message doesn't send to host but is
dropped. So host gets time out and WoW suspend failed.

Just when resume from WoW, the write to select_window doesn't take
effect immediately, so read the register again to ensure the write
operation is finished.
Another change is to reset select_window to ZERO because this
register isn't restored after WoW, so the content of this register
becomes ZERO too.

Currently 6G specific tlvs have duplicate entries which is causing
scan failures. Fix this by removing the duplicate entries of the same
tlv. This also fixes out-of-bound memory writes caused due to
adding tlvs when num_hint_bssid and num_hint_s_ssid are ZEROs.
