This driver does not properly map jack pins to kcontrols that PulseAudio
and PipeWire need to handle jack detection events. The DA7219 codec used
here can detect Headphones, Headset Mic and Line Out connections. Expose
each to userspace as kcontrols and add the necessary widgets.

This patch suggests enabling pm_runtime during the probe, but marking the
device as 'active' only after it is enumerated. That will force a
dependency between the card and the codec, pm_runtime_get_sync() will
have to wait for the codec device to resume and hence implicitly wait
for the enumeration/initialization to be completed. In the nominal
case where the codec device is already active the get_sync() would
only perform a ref-count increase.
The changes are directly inspired by RT711 and RT711-sdca changes.

In stress cases involving module insertion/removal followed by
playback/capture, it can happen that capture/playback is started
before the codec enumeration completes.
The codec driver registers its components with the ASoC framework
during the probe stage, so there is currently no way for the card
creation to wait for the codec enumeration/initialization to complete.
In addition, when the capture/playback starts, the ASoC framework uses
pm_runtime_get_sync() to properly refcount and power-manage
devices. This is problematic in the SoundWire case because pm_runtime
is enabled during the enumeration/initialization stage, so
pm_runtime_get_sync() will return -EACCESS which is
ignored. Additional errors will happen when setting the pm_runtime
status as 'active' because the parent is not properly resumed,
resulting in an error such as:
"rt711 sdw:0:025d:0711:00: runtime PM trying to activate child device
sdw:0:025d:0711:00 but parent (sdw-master-0) is not active"

The RT5682 needs specific attention: there are two regmap in
rt5682_priv struct, one is sdw_regmap which is for IO transfer, and
the other is used for registers control.
We need to set both regmaps when we set cache only. Because if we set
rt5682->sdw_regmap only, rt5682->regmap won't set/get the right value
when it call regmap_write/read(rt5682->sdw_regmap, ...). If we set
rt5682->regmap only, regmap_write(rt5682->sdw_regmap, ...) is used
in rt5682_clock_config which will be called by the ..bus_config ops.

The SoundWire bus may start after the probe where the SoundWire ASoC
components are registered. This creates a time window where the card
can be created and the registers be accessed.
As discussed on the mailing list, we can't really control when codecs
are enumerated and initialized, but we can make sure the access to the
codecs is cached until the hardware is accessible.
This patch configures regcache_cache_only() with a 'true' parameter in
the probe function, and a 'false' parameter in the io_init routine.
The rt5682 is handled through a different patch due to its specific
cache handling.

On a laptop with hibernation set up but not actively used, and with
secure boot and lockdown enabled kernel, 6.5-rc1 gets stuck on boot with
the following repeated messages:
A start job is running for Resume from hibernation using device /dev/system/swap (24s / no limit)
lockdown_is_locked_down: 25311154 callbacks suppressed
Lockdown: systemd-hiberna: hibernation is restricted; see man kernel_lockdown.7
...
Checking the resume code leads to commit cc89c63e2fe3 ("PM: hibernate:
move finding the resume device out of software_resume") which
inadvertently changed the return value from resume_store() to 0 when
!hibernation_available(). This apparently translates to userspace
write() returning 0 as in number of bytes written, and userspace looping
indefinitely in the attempt to write the intended value.
Fix this by returning the full number of bytes that were to be written,
as that's what was done before the commit.

The SBPB bit in MSR_IA32_PRED_CMD is supported only after a microcode
patch has been applied so set X86_FEATURE_SBPB only then. Otherwise,
guests would attempt to set that bit and #GP on the MSR write.
While at it, make SMT detection more robust as some guests - depending
on how and what CPUID leafs their report - lead to cpu_smt_control
getting set to CPU_SMT_NOT_SUPPORTED but SRSO_NO should be set for any
guest incarnation where one simply cannot do SMT, for whatever reason.

A couple of hardware registers need to be set to reflect which
interrupts have been allocated to the device. Each register is 32-bit
wide and can receive four 8-bit values. If we provide any other interrupt
number than four, the irq_num variable will never be 0 within the while
check and the while block will loop forever.
There is an easy way to prevent this: just break the for loop
when we reach "irq_num == 0", which anyway means all interrupts have
been processed.

Disabling IDXD device doesn't reset Page Request Service (PRS)
disable flag to its initial value 0. This may cause user confusion
because once PRS is disabled user will see PRS still remains the
previous setting (i.e. disabled) via sysfs interface even after the
device is disabled.
To eliminate user confusion, reset PRS disable flag to ensure that
the PRS flag bit reflects correct state after the device is disabled.
Additionally, simplify the code by setting wq->flags to 0, which clears
all flag bits, including any future additions.

pl330_pause() does not set anything to indicate paused condition which

DMA flush after the fix in commit 57e9af7831dc ("serial: 8250_dma: Fix

pause is supported but resume is not which is enough for 8250 DMA flush
to work as long as DMA status reports DMA_PAUSED when appropriate.
Add PAUSED state for descriptor and mark BUSY descriptors with PAUSED
in pl330_pause(). Return DMA_PAUSED from pl330_tx_status() when the

When 'mcf_edma' is allocated, some space is allocated for a
flexible array at the end of the struct. 'chans' item are allocated, that is
to say 'pdata->dma_channels'.
Then, this number of item is stored in 'mcf_edma->n_chans'.
A few lines later, if 'mcf_edma->n_chans' is 0, then a default value of 64
is set.
This ends to no space allocated by devm_kzalloc() because chans was 0, but
64 items are read and/or written in some not allocated memory.
Change the logic to define a default value before allocating the memory.

ionic_start_queues_reconfig returns an error code if txrx_init fails.
Handle this error code in the relevant places.
This fixes a corner case where the device could get left in a detached
state if the CMB reconfig fails and the attempt to clean up the mess
also fails. Note that calling netif_device_attach when the netdev is
already attached does not lead to unexpected behavior.
Change goto name "errout" to "err_out" to maintain consistency across
goto statements.

Now that we removed ->iterate we don't need to check for either
->iterate or ->iterate_shared in file_needs_f_pos_lock(). Simply check
for ->iterate_shared instead. This will tell us whether we need to
unconditionally take the lock. Not just does it allow us to avoid
checking f_inode's mode it also actually clearly shows that we're
locking because of readdir.

All users now just use '->iterate_shared()', which only takes the
directory inode lock for reading.
Filesystems that never got convered to shared mode now instead use a
wrapper that drops the lock, re-takes it in write mode, calls the old
function, and then downgrades the lock back to read mode.
This way the VFS layer and other callers no longer need to care about
filesystems that never got converted to the modern era.
The filesystems that use the new wrapper are ceph, coda, exfat, jfs,
ntfs, ocfs2, overlayfs, and vboxsf.
Honestly, several of them look like they really could just iterate their
directories in shared mode and skip the wrapper entirely, but the point
of this change is to not change semantics or fix filesystems that
haven't been fixed in the last 7+ years, but to finally get rid of the
dual iterators.

I'm looking at the directory handling due to the discussion about f_pos
locking (see commit 797964253d35: "file: reinstate f_pos locking
optimization for regular files"), and wanting to clean that up.
And one source of ugliness is how we were supposed to move filesystems
over to the '->iterate_shared()' function that only takes the inode lock
for reading many many years ago, but several filesystems still use the
bad old '->iterate()' that takes the inode lock for exclusive access.
See commit 6192269444eb ("introduce a parallel variant of ->iterate()")
that also added some documentation stating
Old method is only used if the new one is absent; eventually it will
be removed. Switch while you still can; the old one won't stay.
and that was back in April 2016. Here we are, many years later, and the
old version is still clearly sadly alive and well.
Now, some of those old style iterators are probably just because the
filesystem may end up having per-inode mutable data that it uses for
iterating a directory, but at least one case is just a mistake.
Al switched over most filesystems to use '->iterate_shared()' back when
it was introduced. In particular, the /proc filesystem was converted as
one of the first ones in commit f50752eaa0b0 ("switch all procfs
directories ->iterate_shared()").
But then later one new user of '->iterate()' was then re-introduced by
commit 6d9c939dbe4d ("procfs: add smack subdir to attrs").
And that's clearly not what we wanted, since that new case just uses the
same 'proc_pident_readdir()' and 'proc_pident_lookup()' helper functions
that other /proc pident directories use, and they are most definitely
safe to use with the inode lock held shared.
So just fix it.
This still leaves a fair number of oddball filesystems using the
old-style directory iterator (ceph, coda, exfat, jfs, ntfs, ocfs2,
overlayfs, and vboxsf), but at least we don't have any remaining in the
core filesystems.
I'm going to add a wrapper function that just drops the read-lock and
takes it as a write lock, so that we can clean up the core vfs layer and
make all the ugly 'this filesystem needs exclusive inode locking' be
just filesystem-internal warts.
I just didn't want to make that conversion when we still had a core user
left.

O_TMPFILE is actually __O_TMPFILE|O_DIRECTORY. This means that the old

O_DIRECTORY with -EAGAIN, when in fact the intended test was to check

TLS records end with a 16B tag. For TLS device offload we only
need to make space for this tag in the stream, the device will
generate and replace it with the actual calculated tag.
Long time ago the code would just re-reference the head frag
which mostly worked but was suboptimal because it prevented TCP
from combining the record into a single skb frag. I'm not sure
if it was correct as the first frag may be shorter than the tag.
The commit under fixes tried to replace that with using the page
frag and if the allocation failed rolling back the data, if record
was long enough. It achieves better fragment coalescing but is
also buggy.
We don't roll back the iterator, so unless we're at the end of
send we'll skip the data we designated as tag and start the
next record as if the rollback never happened.
There's also the possibility that the record was constructed
with MSG_MORE and the data came from a different syscall and
we already told the user space that we "got it".
Allocate a single dummy page and use it as fallback.
Found by code inspection, and proven by forcing allocation
failures.

Commit af8b04c63708 ("zram: simplify bvec iteration in
__zram_make_request") changed the bio iteration in zram to rely on the
implicit capping to page boundaries in bio_for_each_segment. But it
failed to care for the fact zram not only care about the page alignment
of the bio payload, but also the page alignment into the device. For
buffered I/O and swap those are the same, but for direct I/O or kernel
internal I/O like XFS log buffer writes they can differ.
Fix this by open coding bio_for_each_segment and limiting the bvec len
so that it never crosses over a page alignment boundary in the device
in addition to the payload boundary already taken care of by
bio_iter_iovec.

Matthieu Baerts says:
====================
mptcp: more fixes for v6.5
Here is a new batch of fixes related to MPTCP for v6.5 and older.
Patches 1 and 2 fix issues with MPTCP Join selftest when manually
launched with '-i' parameter to use 'ip mptcp' tool instead of the
dedicated one (pm_nl_ctl). The issues have been there since v5.18.
Thank you Andrea for your first contributions to MPTCP code in the
upstream kernel!
Patch 3 avoids corrupting the data stream when trying to reset
connections that have fallen back to TCP. This can happen from v6.1.
Patch 4 fixes a race when doing a disconnect() and an accept() in
parallel on a listener socket. The issue only happens in rare cases if
the user is really unlucky since a fix that landed in v6.3 but
backported up to v6.1.
