Every power mode of static power slider has its own AC and DC power
settings.
When the power source changes from AC to DC, corresponding DC thermals
were not updated from PMF config store and this leads the system to always
run on AC power settings.
Fix it by registering with power_supply notifier and apply DC settings
upon getting notified by the power_supply handler.

fscache_create_volume_work() uses wake_up_bit() to wake up the processes
which are waiting for the completion of volume creation. According to
comments in wake_up_bit() and waitqueue_active(), an extra smp_mb() is
needed to guarantee the memory order between FSCACHE_VOLUME_CREATING
flag and waitqueue_active() before invoking wake_up_bit().
Fixing it by using clear_and_wake_up_bit() to add the missing memory
barrier.

The freeing of relinquished volume will wake up the pending volume
acquisition by using wake_up_bit(), however it is mismatched with
wait_var_event() used in fscache_wait_on_volume_collision() and it will
never wake up the waiter in the wait-queue because these two functions
operate on different wait-queues.
According to the implementation in fscache_wait_on_volume_collision(),
if the wake-up of pending acquisition is delayed longer than 20 seconds
(e.g., due to the delay of on-demand fd closing), the first
wait_var_event_timeout() will timeout and the following wait_var_event()
will hang forever as shown below:

Considering that wake_up_bit() is more selective, so fix it by using
wait_on_bit() instead of wait_var_event() to wait for the freeing of
relinquished volume. In addition because waitqueue_active() is used in
wake_up_bit() and clear_bit() doesn't imply any memory barrier, use
clear_and_wake_up_bit() to add the missing memory barrier between
cursor->flags and waitqueue_active().

devlink: fix reload notifications and remove features

Devlink features were introduced to disallow devlink reload calls of
userspace before the devlink was fully initialized. The reason for this
workaround was the fact that devlink reload was originally called
without devlink instance lock held.
However, with recent changes that converted devlink reload to be
performed under devlink instance lock, this is redundant so remove
devlink features entirely.
Note that mlx5 used this to enable devlink reload conditionally only
when device didn't act as multi port slave. Move the multi port check
into mlx5_devlink_reload_down() callback alongside with the other
checks preventing the device from reload in certain states.

calls
This effectively reverts commit 05a7f4a8dff1 ("devlink: Break parameter
notification sequence to be before/after unload/load driver").
Cited commit resolved a problem in mlx5 params implementation,
when param notification code accessed memory previously freed
during reload.
Now, when the params can be registered and unregistered when devlink
instance is registered, mlx5 code unregisters the problematic param
during devlink reload. The fix is therefore no longer needed.
Current behavior is a it problematic, as it sends DEL notifications even
in potential case when reload_down() call fails which might confuse
userspace notifications listener.
So move the reload notifications back where they were originally in
between reload_down() and reload_up() calls.

====================
Adding Sparx5 ES2 VCAP support
This provides the Egress Stage 2 (ES2) VCAP (Versatile Content-Aware
Processor) support for the Sparx5 platform.
The ES2 VCAP is an Egress Access Control VCAP that uses frame keyfields and
previously classified keyfields to apply e.g. policing, trapping or
mirroring to frames.
The ES2 VCAP has 2 lookups and they are accessible with a TC chain id:
- chain 20000000: ES2 Lookup 0
- chain 20100000: ES2 Lookup 1
As the other Sparx5 VCAPs the ES2 VCAP has its own lookup/port keyset
configuration that decides which keys will be used for matching on which
traffic type.
The ES2 VCAP has these traffic classifications:
- IPv4 frames
- IPv6 frames
- Other frames
The ES2 VCAP can match on an ISDX key (Ingress Service Index) as one of the
frame metadata keyfields. The IS0 VCAP can update this key using its
actions, and this allows a IS0 VCAP rule to be linked to an ES2 rule.
This is similar to how the IS0 VCAP and the IS2 VCAP use the PAG
(Policy Association Group) keyfield to link rules.
From user space this is exposed via "chain offsets", so an IS0 rule with a
"goto chain 20000015" action will use an ISDX key value of 15 to link to a
rule in the ES2 VCAP attached to the same chain id.

This ensures that it will be possible for a VCAP rule to distinguish IPv6
frames from non-IP frames, as the IS0 keyset usually selected for the IPv6

If you call listen() and accept() on an already connect()ed
AF_NETROM socket, accept() can successfully connect.
This is because when the peer socket sends data to sendmsg,
the skb with its own sk stored in the connected socket's
sk->sk_receive_queue is connected, and nr_accept() dequeues
the skb waiting in the sk->sk_receive_queue.
As a result, nr_accept() allocates and returns a sock with
the sk of the parent AF_NETROM socket.
And here use-after-free can happen through complex race conditions:
```
cpu0 cpu1
1. socket_2 = socket(AF_NETROM)
.
.
listen(socket_2)
accepted_socket = accept(socket_2)

connect(socket_1)
3. write(accepted_socket)

sock_queue_rcv_skb()
sock_queue_rcv_skb_reason()
__sock_queue_rcv_skb()

4. listen(socket_1)

5. close(accepted_socket)

Currently in phy_init_eee() the driver unconditionally configures the PHY
to stop RX_CLK after entering Rx LPI state. This causes an LPI interrupt

This reverts commit 7efc3b7261030da79001c00d92bc3392fd6c664c.
We have got openSUSE reports (Link 1) for 6.1 kernel with khugepaged
stalling CPU for long periods of time. Investigation of tracepoint data
shows that compaction is stuck in repeating fast_find_migrateblock()
based migrate page isolation, and then fails to migrate all isolated
pages.
Commit 7efc3b726103 ("mm/compaction: fix set skip in fast_find_migrateblock")
was suspected as it was merged in 6.1 and in theory can indeed remove a
termination condition for fast_find_migrateblock() under certain
conditions, as it removes a place that always marks a scanned pageblock
from being re-scanned. There are other such places, but those can be
skipped under certain conditions, which seems to match the tracepoint
data.
Testing of revert also appears to have resolved the issue, thus revert
the commit until a more robust solution for the original problem is
developed.
It's also likely this will fix qemu stalls with 6.1 kernel reported in
Link 2, but that is not yet confirmed.

Joe found another DT file that shouldn't be executable, and that
frustrated me enough that I went hunting with this script:
git ls-files -s |
grep '^100755' |
cut -f2 |
xargs grep -L '^#!'
and that found another file that shouldn't have been marked executable
either, despite being in the scripts directory.
Maybe these two are the last ones at least for now. But I'm sure we'll
be back in a few years, fixing things up again.

"tcpdump" is used to capture traffic in these tests while using a random,
temporary and not suffixed file for it. This can interfere with apparmor
configuration where the tool is only allowed to read from files with
'known' extensions.
The MINE type application/vnd.tcpdump.pcap was registered with IANA for
pcap files and .pcap is the extension that is both most common but also
aligned with standard apparmor configurations. See TCPDUMP(8) for more
details.
This improves compatibility with standard apparmor configurations by
using ".pcap" as the file extension for the tests' temporary files.

Kornel Dulęba says:
====================
net: wwan: t7xx: Fix Runtime PM implementation
d10b3a695ba0 ("net: wwan: t7xx: Runtime PM") introduced support for
Runtime PM for this driver, but due to a bug in the initialization logic
the usage refcount would never reach 0, leaving the feature unused.
This patchset addresses that, together with a bug found after runtime
suspend was enabled.
====================

For PCI devices the Runtime PM refcount is incremented twice:
1. During device enumeration with a call to pm_runtime_forbid.
2. Just before a driver probe logic is called.
Because of that in order to enable Runtime PM on a given device
we have to call both pm_runtime_allow and pm_runtime_put_noidle,
once it's ready to be runtime suspended.
The former was missing causing the pm refcount to never reach 0.

Resume device before calling napi_schedule, instead of doing in the napi
poll routine. Polling is done in softrq context. We can't call the PM
resume logic from there as it's blocking and not irq safe.
In order to make it work modify the interrupt handler to be run from irq
handler thread.

For large ranges (outside of s16) the documentation currently
recommends open-coding the validation, but it's better to use
the NLA_POLICY_FULL_RANGE() or NLA_POLICY_FULL_RANGE_SIGNED()
policy validation instead; recommend that.
