      Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've got a huge number of patches that improve code
  readability along with minor bug fixes, while we've mainly fixed some
  critical issues in recently-added per-block age-based extent_cache,
  atomic write support, and some folio cases.

  Enhancements:

   - add sysfs nodes to set last_age_weight and manage
     discard_io_aware_gran

   - show ipu policy in debugfs

   - reduce stack memory cost by using bitfield in struct f2fs_io_info

   - introduce trace_f2fs_replace_atomic_write_block

   - enhance iostat support and adds flush commands

  Bug fixes:

   - revert "f2fs: truncate blocks in batch in __complete_revoke_list()"

   - fix kernel crash on the atomic write abort flow

   - call clear_page_private_reference in .{release,invalid}_folio

   - support .migrate_folio for compressed inode

   - fix cgroup writeback accounting with fs-layer encryption

   - retry to update the inode page given data corruption

   - fix kernel crash due to NULL io->bio

   - fix some bugs in per-block age-based extent_cache:
       - wrong calculation of block age
       - update age extent in f2fs_do_zero_range()
       - update age extent correctly during truncation"

      Linus Torvalds authored 
      Pull remoteproc updates from Bjorn Andersson:

 - Support for PRU clients to acquire a control reference to the PRU
   instances is introduced, and the PRU now allows specifying
   firmware-name in Devicetree. sysfs is requested to be read-only when
   the remoteproc instance is consumed by another kernel driver

 - Support for the C7xv DSP on AM62A SoC is introduced

 - The Devicetree binding for the Qualcomm PAS devices are split up in
   multiple files, to better account for the differences in resources
   between them. A number of missing Devicetree bindings are added, and
   the Qualcomm WCNSS binding is converted to YAML

 - A few cleanups are introduced for the Mediatek SCP driver. And a
   sanity check of the firmware image is introduced in the Mediatek
   driver

 - For Qualcomm SC7280 ADSP support is added, MSM8953 gains ADSP and
   modem support, SM6115 and SM8550 gains ADSP, CDSP and modem support,
   and support for pronto v3 support (used on e.g. MSM8953) is added

 - The Qualcomm modem remoteproc driver is modified to use a no-map
   reserved-memory region for it's authentication metadata, in order to
   avoid fatal security violations caused by accesses from Linux during
   the authentication process

 - Support for separate loading of a Devicetree blob is added to the PAS
   driver, and support for the PAS driver to carve out DSM memory for
   the modem is added as well

 - The Qualcomm ADSP remoteproc driver gains support for mapping memory
   into specific range using the IOMMU. The sysmon driver is
   transitioned to strlcpy()

 - rpmsg ctrl and char driver locking is ensure ordering in cases where

 - The glink driver is refactored, to move rpm/smem-specifics out of the
   common logic and better suite further improvements, such as
   transports without a mailbox controller. The handling of remoteproc
   shutdown is improved, to fail clients immediately instead of having
   them to wait for timeouts. A driver_override memory leak is corrected
   and a few spelling improvements are introduced

 - saa7146 recovered from staging/deprecated. We opted to give ti a
   chance, and, instead of deprecating it, the intention is to write
   patches migrating it from VB1 to VB2.

 - av7110 returned from staging/deprecated/ to staging/ as we're not
   planning on dropping it any time soon

 - media controller API has gained experimental support for G_ROUTING
   and streams API. No drivers use it right now. We're planning to add
   one after -rc1, giving some time to experience the API and eventually
   have changes during the next development cycle

 - New sensor drivers: imx296, imx415, ov8858

 - Atomisp had lots of changes, specially on its sensor's interface,
   making atomisp sensor drivers closer to normal sensor drivers

 - media controller kAPI has gained some helpers to traverse pipelines

 - uvcvideo now better support power line control

      Documentation: simplify and clarify DCO contribution example language · d4563201
      Linus Torvalds authored 
      Long long ago, in a more innocent time, Greg wrote the clarification for
how the DCO should work and that you couldn't make anonymous
contributions, because the sign-off needed to be something we could
check back with.

It was 2006, and nobody reacted to the wording, the whole Facebook 'real
name' controversy was a decade in the future, and nobody even thought
about it.  And despite the language, we've always accepted nicknames and
that language was never meant to be any kind of exclusionary wording.

In fact, even when it became a discussion in other adjacent projects,
apparently nobody even thought to just clarify the language in the
kernel docs, and instead we had projects like the CNCF that had long
discussions about it, and wrote their own clarifications [1] of it.

Just simplify the wording to the point where it shouldn't be causing
unnecessary angst and pain, or scare away people who go by preferred
naming.

====================
Regressions in Ocelot switch drivers

These are 3 patches which resolve a regression in the Seville driver,
one in the Felix driver and a generic one which affects any kernel
compiled with 2 Kconfig options enabled. All of them have in common my
lack of attention during review/testing. The patches touch the DSA, MFD
and MDIO drivers for Ocelot. I think it would be preferable if all
patches went through netdev (with Lee's Ack).

      net: dsa: felix: fix internal MDIO controller resource length · 940af261
      Vladimir Oltean authored 
      The blamed commit did not properly convert the resource start/end format
into the DEFINE_RES_MEM_NAMED() start/length format, resulting in a
resource for vsc9959_imdio_res which is much longer than expected:

$ cat /proc/iomem
1f8000000-1f815ffff : pcie@1f0000000
  1f8140000-1f815ffff : 0000:00:00.5
    1f8148030-1f815006f : imdio

vs (correct)

$ cat /proc/iomem
1f8000000-1f815ffff : pcie@1f0000000
  1f8140000-1f815ffff : 0000:00:00.5
    1f8148030-1f814803f : imdio

Luckily it's not big enough to exceed the size of the parent resource
(pci_resource_end(pdev, VSC9959_IMDIO_PCI_BAR)), and it doesn't overlap
with anything else that the Linux driver uses currently, so the larger
than expected size isn't a practical problem that I can see. Although it
is clearly wrong in the /proc/iomem output.

      During the refactoring in the commit below, vsc9953_mdio_read() was

the MSCC_MIIM_DATA_ERROR bits before returning the result.

On T1040RDB, there are 8 QSGMII PCSes belonging to the switch, and they
are organized in 2 groups. First group responds to MDIO addresses 4-7
because QSGMIIACR1[MDEV_PORT] is 1, and the second group responds to
MDIO addresses 8-11 because QSGMIIBCR1[MDEV_PORT] is 2. I have double
checked that these values are correctly set in the SERDES, as well as
PCCR1[QSGMA_CFG] and PCCR1[QSGMB_CFG] are both 0b01.

As can be seen, the data in MIIM_DATA is still valid despite having the
MSCC_MIIM_DATA_ERROR bits set. The driver as introduced in commit
84705fc1 ("net: dsa: felix: introduce support for Seville VSC9953
switch") was ignoring these bits, perhaps deliberately (although
unbeknownst to me).

This is an old IP and the hardware team cannot seem to be able to help
me track down a plausible reason for these failures. I'll keep
investigating, but in the meantime, this is a direct regression which
must be restored to a working state.

The only thing I can do is keep ignoring the errors as before.

net/sched: fix action bind logic

Some actions are not handling the case where an action can be created and bound to a
filter independently. These actions are checking for parameters only passed
in the netlink message for create/change/replace, which then errors out
for valid uses like:
tc filter ... action pedit index 1

In the iproute2 side, we saw a couple of actions with their parsers
broken when passing "index 1" as the only action argument, while the kernel
side accepted it correctly. We fixed those as well.

      net/sched: act_mpls: fix action bind logic · e88d78a7
      Pedro Tammela authored 
      The TC architecture allows filters and actions to be created independently.
In filters the user can reference action objects using:
tc action add action mpls ... index 1
tc filter add ... action mpls index 1

In the current code for act_mpls this is broken as it checks netlink
attributes for create/update before actually checking if we are binding to an
existing action.

      wifi: wext: warn about usage only once · 52fd9063
      Johannes Berg authored 
      Warn only once since the ratelimit parameters are still
allowing too many messages to happen. This will no longer
tell you all the different processes, but still gives a
heads-up of sorts.

Also modify the message to note that wext stops working
for future Wi-Fi 7 hardware, this is already implemented
in commit 4ca69027 ("wifi: wireless: deny wireless
extensions on MLO-capable devices") and is maybe of more
relevance to users than the fact that we'd like to have
wireless extensions deprecated.

The issue with Wi-Fi 7 is that you can now have multiple
connections to the same AP, so a whole bunch of things
now become per link rather than per netdev, which can't
really be handled in wireless extensions.

      qede: avoid uninitialized entries in coal_entry array · aaa3c08e
      Michal Schmidt authored 
      Even after commit 908d4bb7 ("qede: fix interrupt coalescing
configuration"), some entries of the coal_entry array may theoretically
be used uninitialized:

 1. qede_alloc_fp_array() allocates QEDE_MAX_RSS_CNT entries for
    coal_entry. The initial allocation uses kcalloc, so everything is
    initialized.
 2. The user sets a small number of queues (ethtool -L).
    coal_entry is reallocated for the actual small number of queues.
 3. The user sets a bigger number of queues.
    coal_entry is reallocated bigger. The added entries are not
    necessarily initialized.

In practice, the reallocations will actually keep using the originally
allocated region of memory, but we should not rely on it.

The reallocation is unnecessary. coal_entry can always have
QEDE_MAX_RSS_CNT entries.
