Reportedly, clang cannot do interprocedural analysis:
https://lore.kernel.org/r/20230213-amd64_edac-wsometimes-uninitialized-v1-1-5bde32b89e02@kernel.org
and see that those arguments won't be used uninitialized.
So, yeah, the code's fine even without this. Normally, such a "fix"
won't be applied but that warning gets automatically enabled in -Wall
builds and when CONFIG_WERROR is set in allmodconfig builds, the build
fails.
So shut it up with a minimal fix as this code will see more
reorganization very soon.

During removal of the glink edge interrupts are disabled and no more
incoming messages are being serviced. In addition to the remote endpoint
being defunct that means that any outstanding requests for intents will
not be serviced, and qcom_glink_request_intent() will blindly wait for
up to 10 seconds.
Mark the intent request as not granted and complete the intent request
completion to fail the waiting client immediately.
Once the current intent request is failed, any potential clients waiting
for the intent request mutex will not enter the same wait, as the
qcom_glink_tx() call will fail fast.

Upon removing the glink edge, communication is at best one-way. This
means that the very common scenario of glink requesting intents will not
be possible to serve.
Typically a successful transmission results in the client waiting for a
response, with some timeout and a mechanism for aborting that timeout.
Because of this, once the glink edge is defunct once removal is
commenced it's better to fail transmissions fast.

Not all GLINK transports uses an interrupt and a mailbox instance. The
interrupt for RPM needs to be IRQF_NOSUSPEND, while it seems reasonable
for the SMEM interrupt to use irq_set_wake. The glink struct device is
constructed in the SMEM and RPM drivers but torn down in the core
driver.
Move the interrupt and kick handling into the SMEM and RPM driver, to
improve this and facilitate further improvements.

Group some variables based on their sizes to reduce hole and avoid padding.
On x86_64, this shrinks the size from 144 to 128 bytes.
Turn 'timestamped' into a bitfield so that it can be easily merged with
some other bifields and move 'error'.
This should have no real impact on memory allocation because 'struct
spi_transfer' is mostly used on stack, but it can save a few cycles
when the structure is initialized or copied.

Fix the issue where some flash chips like cypress S25HS256T return the
value of the same register over and over in DAC mode.
For example in the TI K3-AM62x Processors refer [0] Technical Reference
Manual there is a layer of digital logic in front of the QSPI/OSPI
Drive when used in DAC mode. This is part of the Flash Subsystem (FSS)
which provides access to external Flash devices.
The FSS0_0_SYSCONFIG Register (Offset = 4h) has a BIT Field for
OSPI_32B_DISABLE_MODE which has a Reset value = 0. This means, OSPI 32bit
mode enabled by default.
Thus, by default controller operates in 32 bit mode causing it to always
align all data to 4 bytes from a 4byte aligned address. In some flash
chips like cypress for example if we try to read some regs in DAC mode
then it keeps sending the value of the first register that was requested
and inorder to read the next reg, we have to stop and re-initiate a new
transaction.
This causes wrong register values to be read than what is desired when
registers are read in DAC mode. Hence if the data.nbytes is very less
then prefer STIG mode for such small reads.

Setup the Addr bit field while issuing register reads in STIG mode. This
is needed for example flashes like cypress define in their transaction
table that to read any register there is 1 cmd byte and a few more address
bytes trailing the cmd byte. Absence of addr bytes will obviously fail
to read correct data from flash register that maybe requested by flash
driver because the controller doesn't even specify which address of the
flash register the read is being requested from.

The current mac80211 mesh A-MSDU receive path fails to parse A-MSDU packets
on mesh interfaces, because it assumes that the Mesh Control field is always
directly after the 802.11 header.
802.11-2020 9.3.2.2.2 Figure 9-70 shows that the Mesh Control field is
actually part of the A-MSDU subframe header.
This makes more sense, since it allows packets for multiple different
destinations to be included in the same A-MSDU, as long as RA and TID are
still the same.
Another issue is the fact that the A-MSDU subframe length field was apparently
accidentally defined as little-endian in the standard.
In order to fix this, the mesh forwarding path needs happen at a different
point in the receive path.
ieee80211_data_to_8023_exthdr is changed to ignore the mesh control field
and leave it in after the ethernet header. This also affects the source/dest
MAC address fields, which now in the case of mesh point to the mesh SA/DA.
ieee80211_amsdu_to_8023s is changed to deal with the endian difference and
to add the Mesh Control length to the subframe length, since it's not covered
by the MSDU length field.
With these changes, the mac80211 will get the same packet structure for
converted regular data packets and unpacked A-MSDU subframes.
The mesh forwarding checks are now only performed after the A-MSDU decap.
For locally received packets, the Mesh Control header is stripped away.
For forwarded packets, a new 802.11 header gets added.

It is a frequent mistake to confuse the netlink port identifier with a
process identifier. Try to reduce this confusion by renaming
that hold port identifiers portid instead of pid.
This change replicates following commit:
commit 15e473046cb6 ("netlink: Rename pid to portid to avoid confusion")

Add support to offload OWE processing to user space for MLD AP when
driver's SME in use.
Add new parameters in struct cfg80211_update_owe_info to provide below
information in cfg80211_update_owe_info_event() call:
- MLO link ID of the AP, with which station requested (re)association.
This is applicable for both MLO and non-MLO station connections when
the AP affiliated with an MLD.
- Station's MLD address if the connection is MLO capable.

The logic in vfio_ccw_sch_shutdown() always assumed that the input
subchannel would point to a vfio_ccw_private struct, without checking
that one exists. The blamed commit put in a check for this scenario,
to prevent the possibility of a missing private.
The trouble is that check was put alongside a WARN_ON(), presuming
that such a scenario would be a cause for concern. But this can be
triggered by binding a subchannel to vfio-ccw, and rebooting the
system before starting the mdev (via "mdevctl start" or similar)
or after stopping it. In those cases, shutdown doesn't need to
worry because either the private was never allocated, or it was
cleaned up by vfio_ccw_mdev_remove().
Remove the WARN_ON() piece of this check, since there are plausible
scenarios where private would be NULL in this path.

Extend the action stats callback implementation to update stats for actions
that are associated with hw counters.
Note that the callback may be called from tc action utility or from tc
flower. Both apis expect the driver to return the stats difference from
the last update. As such, query the raw counter value and maintain
the diff from the last api call in the tc layer, instead of the fs_core
layer.

Currently a hardware counter is associated with a flow cookie.
This does not apply to flows using branching action which are required to
return per action stats.
A single counter may apply to multiple actions.
Scan the flow actions in reverse (from the last to the first action) while
caching the last counter.
Associate all the flow attribute tc action cookies with the current
cached counter.

The tc parse action phase translates the tc actions to mlx5 flow
attributes data structure that is used during the flow offload phase.
Currently, the flow offload stage instantiates hw counters while
associating them to flow cookie. However, flows with branching
actions are required to associate a hardware counter with its action
cookies.
Store the parsed tc action cookies on the flow attribute.
Use the list of cookies in the next patch to associate a tc action cookie
with its allocated hw counter.

Currently a hw count action is appended to the last action of the action
list. However, a branching action may terminate the action list before
reaching the last action.
Append a count action to a branching action.
In the next patches, filters with branching actions will read this counter
when reporting stats per action.

When setting 'snps,force_thresh_dma_mode' DT property, the following
warning is always emitted, regardless the status of force_sf_dma_mode:
dwmac-starfive 10020000.ethernet: force_sf_dma_mode is ignored if force_thresh_dma_mode is set.
Do not print the rather misleading message when DMA store and forward
mode is already disabled.
