This reverts commit 1e7f6def8b2370ecefb54b3c8f390ff894b0c51b.
It causes my machine to not even boot, and Klara Modin reports that the
cause is that small zstd-compressed files return garbage when read.

When afs does a lookup, it tries to use FS.InlineBulkStatus to preemptively
look up a bunch of files in the parent directory and cache this locally, on
the basis that we might want to look at them too (for example if someone
does an ls on a directory, they may want want to then stat every file
listed).
FS.InlineBulkStatus can be considered a compound op with the normal abort
code applying to the compound as a whole. Each status fetch within the
compound is then given its own individual abort code - but assuming no
error that prevents the bulk fetch from returning the compound result will
be 0, even if all the constituent status fetches failed.
At the conclusion of afs_do_lookup(), we should use the abort code from the
appropriate status to determine the error to return, if any - but instead
it is assumed that we were successful if the op as a whole succeeded and we
return an incompletely initialised inode, resulting in ENOENT, no matter
the actual reason. In the particular instance reported, a vnode with no
permission granted to be accessed is being given a UAEACCES abort code
which should be reported as EACCES, but is instead being reported as
ENOENT.
Fix this by abandoning the inode (which will be cleaned up with the op) if
file[1] has an abort code indicated and turn that abort code into an error
instead.
Whilst we're at it, add a tracepoint so that the abort codes of the
individual subrequests of FS.InlineBulkStatus can be logged. At the moment
only the container abort code can be 0.

There appears to be a race between silly-rename files being created/removed
and various userspace tools iterating over the contents of a directory,
leading to such errors as:
find: './kernel/.tmp_cpio_dir/include/dt-bindings/reset/.__afs2080': No such file or directory
tar: ./include/linux/greybus/.__afs3C95: File removed before we read it
when building a kernel.
Fix afs_readdir() so that it doesn't return .__afsXXXX silly-rename files
to userspace. This doesn't stop them being looked up directly by name as
we need to be able to look them up from within the kernel as part of the
silly-rename algorithm.

The problem appears to be caused by CPU reordering of writes issued from
__tracing_map_insert().
The check for the presence of an element with a given key in this
function is:
val = READ_ONCE(entry->val);
if (val && keys_match(key, val->key, map->key_size)) ...
The write of a new entry is:
elt = get_free_elt(map);
memcpy(elt->key, key, map->key_size);
entry->val = elt;
The "memcpy(elt->key, key, map->key_size);" and "entry->val = elt;"
stores may become visible in the reversed order on another CPU. This
second CPU might then incorrectly determine that a new key doesn't match
an already present val->key and subsequently insert a new element,
resulting in a duplicate.
Fix the problem by adding a write barrier between
"memcpy(elt->key, key, map->key_size);" and "entry->val = elt;", and for
good measure, also use WRITE_ONCE(entry->val, elt) for publishing the
element. The sequence pairs with the mentioned "READ_ONCE(entry->val);"
and the "val->key" check which has an address dependency.
The barrier is placed on a path executed when adding an element for
a new key. Subsequent updates targeting the same key remain unaffected.
From the user's perspective, the issue was introduced by commit
c193707dde77 ("tracing: Remove code which merges duplicates"), which
followed commit cbf4100efb8f ("tracing: Add support to detect and avoid
duplicates"). The previous code operated differently; it inherently
expected potential races which result in duplicates but merged them
later when they occurred.

Merge series from Johan Hovold <[email protected]>:
To reduce the risk of speaker damage the PA gain needs to be limited on
machines like the Lenovo Thinkpad X13s until we have active speaker
protection in place.
Limit the gain to the current default setting provided by the UCM
configuration which most user have so far been using (due to a bug in
the configuration files which prevented hardware volume control [1]).
The wsa883x PA volume control also turned out to be broken, which meant
that the default setting used by UCM configuration is actually the
lowest level (-3 dB). With the codec driver fixed, hardware volume
control also works as expected.
Note that the new wsa884x driver most likely suffers from a similar bug,
I'll send a fix for that once I've got that confirmed.
Included is also a related fix for the LPASS WSA macro driver, which
was changing the digital gain setting behind the back of user space and
which can result in excessive (or too low) digital gain.
There are further Qualcomm codec drivers that similarly appear to
manipulate various gain settings, but on closer inspection it turns out
that they only write back the current settings. Tests reveal that these
writes are indeed needed for any prior updates to take effect (at least
for the WSA and RX macros).

Currently, both ATA_LPM_UNKNOWN (0) and ATA_LPM_MAX_POWER (1) displays
as "max_performance" in sysfs.
This is quite misleading as they are not the same.
For ATA_LPM_UNKNOWN, ata_eh_set_lpm() will not be called at all,
leaving the configuration in unknown state.
For ATA_LPM_MAX_POWER, ata_eh_set_lpm() is called, and setting the
policy to ATA_LPM_MAX_POWER.
This also matches the description of the SATA_MOBILE_LPM_POLICY Kconfig:
0 => Keep firmware settings
1 => Maximum performance
Thus, update the sysfs description for ATA_LPM_UNKNOWN to match reality.
While at it, update libata.h to mention that the ascii descriptions
are in libata-sata.c and not in libata-scsi.c.

The UCM configuration for the Lenovo ThinkPad X13s has up until now
been setting the speaker PA volume to the minimum -3 dB when enabling
the speakers, but this does not prevent the user from increasing the
volume further.
Limit the digital gain and PA volumes to a combined -3 dB in the machine
driver to reduce the risk of speaker damage until we have active speaker
protection in place (or higher safe levels have been established).
Note that the PA volume limit cannot be set lower than 0 dB or
PulseAudio gets confused when the first 16 levels all map to -3 dB.
Also note that this will probably need to be generalised using
machine-specific limits, but a common limit should do for now.

CXL 3.1 Section 3.1.1 states:
"A Function on a CXL device must not generate INTx messages if
that Function participates in CXL.cache protocol or CXL.mem
protocols."
The generic CXL memory driver only supports devices which use the
CXL.mem protocol. The current driver attempts to allocate MSI/MSI-X
vectors in anticipation of their need for mailbox interrupts or event
processing. However, the above requirement does not require a device to
support interrupts, only that they use MSI/MSI-X. For example, a device
may disable mailbox interrupts and either be configured for firmware
first or skip event processing and function.
Dave Larsen reported that the following Intel / Agilex card does not
support interrupts on function 0.
CXL: Intel Corporation Device 0ddb (rev 01) (prog-if 10 [CXL Memory Device (CXL 2.x)])
Rather than fail device probe if interrupts are not supported; flag that
irqs are not enabled and avoid features which require interrupts.
Emit messages appropriate for the situation to aid in debugging should
device behavior be unexpected due to a failure to allocate vectors.
Note that it is possible for a device to have host based event
processing through polling. However, the driver does not support
polling and it is not anticipated to be generally required. Leave that
functionality to a future patch if such a device comes along.

Pull stringop-overflow warning update from Gustavo A. R. Silva:
"Enable -Wstringop-overflow globally.
I waited for the release of -rc1 to run a final build-test on top of
it before sending this pull request. Fortunatelly, after building 358
kernels overnight (basically all supported archs with a wide variety
of configs), no more warnings have surfaced! :)
Thus, we are in a good position to enable this compiler option for all
versions of GCC that support it, with the exception of GCC-11, which
appears to have some issues with this option [1]"

Pull xen netback fix from Juergen Gross:
"Transmit requests in Xen's virtual network protocol can consist of
multiple parts. While not really useful, except for the initial part
any of them may be of zero length, i.e. carry no data at all.
Besides a certain initial portion of the to be transferred data, these
parts are directly translated into what Linux calls SKB fragments.
Such converted request parts can, when for a particular SKB they are
all of length zero, lead to a de-reference of NULL in core networking
code"

REQ_OP_FLUSH is only for internal use in the blk-mq and request based
drivers. File systems and other block layer consumers must use
REQ_OP_WRITE | REQ_PREFLUSH as documented in
Documentation/block/writeback_cache_control.rst.
While REQ_OP_FLUSH appears to work for blk-mq drivers it does not
get the proper flush state machine handling, and completely fails
for any bio based drivers, including all the stacking drivers. The
block layer will also get a check in 6.8 to reject this use case
entirely.
[Note: completely untested, but as this never got fixed since the
original bug report in November:
https://bugzilla.kernel.org/show_bug.cgi?id=218184
and the the discussion in December:
https://lore.kernel.org/all/[email protected]/T/
this seems to be best way to force it]

Similar to commit 26db46bc9c67 ("drm/bridge: parade-ps8640: Ensure bridge
is suspended in .post_disable()"). Add a mutex to ensure that aux transfer
won't race with atomic_disable by holding the PM reference and prevent
the bridge from suspend.
Also we need to use pm_runtime_put_sync_suspend() to suspend the bridge
instead of idle with pm_runtime_put_sync().

Commit 1a721de8489f ("block: don't add or resize partition on the disk
with GENHD_FL_NO_PART") prevented all operations about partitions on disks
with GENHD_FL_NO_PART in blkpg_do_ioctl() since they are meaningless.
However, it changed error code in some scenarios. So move checking
GENHD_FL_NO_PART to bdev_add_partition() to eliminate impact.

Merge series from Neil Armstrong <[email protected]>:
Add the main WCD9390/WCD9395 Audio Codec driver to support:
- 4 ADC inputs for up to 5 Analog Microphones
- 4 DMIC inputs for up to 8 Digital Microphones
- 4 Microphone BIAS
- Stereo Headphone output
- Mono EAR output
- MBHC engine for Headset Detection
This adds:
- bindings
- MBHC changes to support Type-C muc
- Soundwire Slave driver
- Code driver
The USB Mux subsystem support will be submitted separately
since it's a functionally separate subsystem connected over
I2C with it's own reset signal.

Merge series from Cristian Ciocaltea <[email protected]>:
This patch series is a continuation of [1] to provide several fixes and
improvements to the SOF drivers targeting the Vangogh platform, as found on
Valve's Steam Deck OLED. The previous series only handled the legacy ACP
drivers.
Also note that, since v2, this patch series requires an updated SOF
topology to provide a correct DAI link ID for the BT codec. The binary
file should be located under:
/usr/lib/firmware/amd/sof-tplg/sof-vangogh-nau8821-max.tplg
Alternatively, as a temporary workaround, patch [2] can be used to adapt
the driver to the broken topology.
Another requirement to get this functional is patch [3] from v1, which has
been dropped from the series to be upstreamed via the SOF development
workflow.

Turns out this "SoC" side controller does not support certain commands,
such as reading chip JEDEC ID, so the controller is pretty much unusable
in Linux. We should be using the "PCH" side controller instead. For this
reason remove this PCI ID from the list.
