Convert the MediaTek MT8183 AFE PCM Device Tree binding from the old
.txt format to dt-schema format to improve validation.
While converting, also document all clock inputs and memory-region

Add new property: cirrus,subsystem-id
This new property is used to uniquely identify the system if device
tree is used, to allow the driver to select the correct firmware and
tuning for the system.
The DSP driver searches for a compatible firmware (and tuning) based on
what it is able to read from the hardware.
However, the SSID is based on the system, and cannot be read from the
hardware, therefore it needs to be read from the Device Tree.
On ACPI-based systems, it is able to read this from the ACPI _SUB
property, and to maintain compatibility with the driver between ACPI
and Device Tree systems we need an equivalent property.

In io_link_skb function, there is a bug where prev_notif is incorrectly

of comparing it with the previous notification.

The AMD IOMMU host page table implementation supports dynamic page table levels
(up to 6 levels), starting with a 3-level configuration that expands based on
IOVA address. The kernel maintains a root pointer and current page table level
to enable proper page table walks in alloc_pte()/fetch_pte() operations.
The IOMMU IOVA allocator initially starts with 32-bit address and onces its
exhuasted it switches to 64-bit address (max address is determined based
on IOMMU and device DMA capability). To support larger IOVA, AMD IOMMU
driver increases page table level.
But in unmap path (iommu_v1_unmap_pages()), fetch_pte() reads
pgtable->[root/mode] without lock. So its possible that in exteme corner case,
when increase_address_space() is updating pgtable->[root/mode], fetch_pte()
reads wrong page table level (pgtable->mode). It does compare the value with
level encoded in page table and returns NULL. This will result is
iommu_unmap ops to fail and upper layer may retry/log WARN_ON.
CPU 0 CPU 1
------ ------
map pages unmap pages
alloc_pte() -> increase_address_space() iommu_v1_unmap_pages() -> fetch_pte()
pgtable->root = pte (new root value)
READ pgtable->[mode/root]
Reads new root, old mode
Updates mode (pgtable->mode += 1)
Since Page table level updates are infrequent and already synchronized with a
spinlock, implement seqcount to enable lock-free read operations on the read path.

In non-interleaved mode, several QMC channels are used in sync.
More details can be found in commit 188d9cae5438 ("ASoC: fsl:
fsl_qmc_audio: Add support for non-interleaved mode.")
At the time being, an interrupt is requested on each channel to
perform capture/playback completion, allthough the completion is
really performed only once all channels have completed their work.
This leads to a lot more interrupts than really needed. Looking at
/proc/interrupts shows ~3800 interrupts per second when using
4 capture and 4 playback devices with 5ms periods while
only 1600 (200 x 4 + 200 x 4) periods are processed during one second.
The QMC channels work in sync, the one started first is the one
finishing first and the one started last is the one finishing last,
so when the last one finishes it is guaranteed that the other ones are
finished as well. Therefore only request completion processing on the
last QMC channel.
On my board with the above exemple, on a kernel started with
'threadirqs' option, the QMC irq thread uses 16% CPU time with this
patch while it uses 26% CPU time without this patch.

Fix a potential integer overflow vulnerability in trace_filter_parse()
where the allocation size calculation could overflow.
The issue occurs when:
1. capacity is calculated by adding TRACE_FILTER_ELEMENTS_PER_ENTRY in a
loop for each entry found in the input string.
2. capacity * sizeof(**out) multiplication could overflow if many
entries are present in the input.
3. This results in a smaller allocation than expected, leading to
potential buffer overflow.
Replace kmalloc() with kmalloc_array() which provides built-in overflow
checking and will safely fail the allocation if overflow would occur,
preventing memory corruption.

(a) return container_of(dapm, struct snd_soc_component, dapm);
}
dapm of component works, but dapm of card will be "unknown" pointer
(= not NULL), because (a) is using "container_of()".
OTOH, ASoC will call snd_soc_dapm_init() (X) to initialize dapm, and
it will be called from snd_soc_bind_card() (p) (for card) or
soc_probe_component() (q) (for component) with component pointer.
(p) static int snd_soc_bind_card(...)
{
...
(X) snd_soc_dapm_init(..., NULL);
... ^^^^
}
(q) static int soc_probe_component(...)
{
...
(X) snd_soc_dapm_init(..., component);
... ^^^^^^^^^
}
And snd_soc_dapm_init() (X) will fill dapm->component (x)
(X) void snd_soc_dapm_init(..., component, ...)
{
...
(x) dapm->component = component;
...
}
We can simply use dapm->component in snd_soc_dapm_to_component() (A).
In this case, dapm of card (p) will be just NULL.
Use dapm->component instead of container_of().
The picky note can be removed by this patch.

Because struct snd_soc_dapm_context is soc-dapm framework specific, user
driver don't need to access its member directly, we would like to hide
them. struct snd_soc_dapm_context will be removed from header in the
future.
Some drivers need to get card from dapm (which will be removed).
We need such function. Add it.

A recent commit:
fc582cd26e88 ("io_uring/msg_ring: ensure io_kiocb freeing is deferred for RCU")
fixed an issue with not deferring freeing of io_kiocb structs that
msg_ring allocates to after the current RCU grace period. But this only
covers requests that don't end up in the allocation cache. If a request
goes into the alloc cache, it can get reused before it is sane to do so.
A recent syzbot report would seem to indicate that there's something
there, however it may very well just be because of the KASAN poisoning
that the alloc_cache handles manually.
Rather than attempt to make the alloc_cache sane for that use case, just
drop the usage of the alloc_cache for msg_ring request payload data.
Fixes: 50cf5f3842af ("io_uring/msg_ring: add an alloc cache for io_kiocb entries")

is stop the runlist so GFX can enter gfxoff.
