Drop static const arrays with HSI2 clocks parent data which are not
referenced by any clock. This might cause -Werror=unused-const-variable

Daniel Jurgens says:
====================
Remove RTNL lock protection of CVQ
Currently the buffer used for control VQ commands is protected by the
RTNL lock. Previously this wasn't a major concern because the control VQ
was only used during device setup and user interaction. With the recent
addition of dynamic interrupt moderation the control VQ may be used
frequently during normal operation.
This series removes the RNTL lock dependency by introducing a mutex
to protect the control buffer and writing SGs to the control VQ.
v6:
- Rebased over new stats code.
- Added comment to cvq_lock, init the mutex unconditionally,
and replaced some duplicate code with a goto.
- Fixed minor grammer errors, checkpatch warnings, and clarified
a comment.
v5:
- Changed cvq_lock to a mutex.
- Changed dim_lock to mutex, because it's held taking
the cvq_lock.
- Use spin/mutex_lock/unlock vs guard macros.
v4:
- Protect dim_enabled with same lock as well intr_coal.
- Rename intr_coal_lock to dim_lock.
- Remove some scoped_guard where the error path doesn't
have to be in the lock.
v3:
- Changed type of _offloads to __virtio16 to fix static
analysis warning.
- Moved a misplaced hunk to the correct patch.
v2:
- New patch to only process the provided queue in
virtnet_dim_work
- New patch to lock per queue rx coalescing structure.

Once the RTNL locking around the control buffer is removed there can be

Allocate memory for the data when it's used. Ideally the struct could
be on the stack, but we can't DMA stack memory. With this change only
the header and status memory are shared between commands, which will
allow using a tighter lock than RTNL.

Currently, the MT7530 DSA subdriver configures the MT7530 switch to provide
direct access to switch PHYs, meaning, the switch PHYs listen on the MDIO
bus the switch listens on. The PHY muxing feature makes use of this.
This is problematic as the PHY may be attached before the switch is
initialised, in which case, the PHY will fail to be attached.
Since commit 91374ba537bd ("net: dsa: mt7530: support OF-based registration
of switch MDIO bus"), we can describe the switch PHYs on the MDIO bus of
the switch on the device tree. Extend the check to detect PHY muxing when
the PHY is defined on the MDIO bus of the switch on the device tree.
When the PHY is described this way, the switch will be initialised first,
then the switch MDIO bus will be registered. Only after these steps, the
PHY will be attached.

Commit 9385/2 introduced a few branches inside function
prototypes when using CFI in order to deal with the situation
where CFI inserts a few bytes of function information in front
of the symbol.
This is not good for older CPUs where every cycle counts.
Commit 9386/2 alleviated the situation a bit by using aliases
for the cache functions with identical signatures.
This leaves the coherent cache flush functions
*_coherent_kern_range() with these branches to the corresponing
*_coherent_user_range() around, since their return type differ and
they therefore cannot be aliased.
Solve this by a simple ifdef so at least we can use fallthroughs
when compiling without CFI enabled.

RISC-V SoC Kconfig Updates for v6.10
A few different bits of SoC-related Kconfig work. The first part of
this is shared with the DT updates - the modification of all SOC_CANAAN
users to SOC_CANAAN_K210 to split the existing m-mode nommu k210 away
from the k230 that is able to be used in a "common" kernel.
The other thing here is the removal of most of the SOC_VENDOR options,
with their ARCH_VENDOR equivalents that've been waiting in the wings for
1 year+ now made visible. Due a lapse on my part when originally adding
the ARCH_VENDOR stuff, the Microchip transition isn't complete - the
_POLARFIRE was a mistake to keep as there's gonna be non-PolarFire
RISC-V stuff from Microchip soonTM.

Cleanup some deprecated uses of strncpy() and strcpy() [1].
There doesn't seem to be any bugs with the current code but the
readability of this code could benefit from a quick makeover while
removing some deprecated stuff as a benefit.
The most interesting replacement made in this patch involves
concatenating "ttyS" with a digit-led user-supplied string. Instead of
doing two distinct string copies with carefully managed offsets and
lengths, let's use the more robust and self-explanatory scnprintf().
scnprintf will 1) respect the bounds of @buf, 2) null-terminate @buf, 3)
do the concatenation. This allows us to drop the manual NUL-byte assignment.
Also, since isdigit() is used about a dozen lines after the open-coded
version we'll replace it for uniformity's sake.
All the strcpy() --> strscpy() replacements are trivial as the source
strings are literals and much smaller than the destination size. No
behavioral change here.
Use the new 2-argument version of strscpy() introduced in Commit
e6584c3964f2f ("string: Allow 2-argument strscpy()"). However, to make
this work fully (since the size must be known at compile time), also
update the extern-qualified declaration to have the proper size
information.

The generic_handle_domain_irq() function calls irq_resolve_mapping().
Thus delete a duplicative irq_find_mapping() call

Currently the documentation for line names allows to use %u inside
the alternative name. This is broken in character device approach
from day 1 and being in use solely in sysfs.
Character device interface has a line number as a part of its address,
so the users better rely on it. Hence remove the misleading documentation.
On top of that, there are no in-kernel users (out of 6, if I'm correct)
for such names and moreover if one exists it won't help in distinguishing
lines with the same naming as '%u' will also be in them and we will get
a warning in gpiochip_set_desc_names() for such cases.

1) Remove Obsolete UDP_ENCAP_ESPINUDP_NON_IKE Support.
This was defined by an early version of an IETF draft
that did not make it to a standard.
2) Introduce direction attribute for xfrm states.
xfrm states have a direction, a stsate can be used
either for input or output packet processing.
Add a direction to xfrm states to make it clear
for what a xfrm state is used.

According to GCC, the constriction of irq_name in otx2_open()
may, theoretically, be truncated.
This patch takes the approach of treating such a situation as an error
which it detects by making use of the return value of snprintf, which is
the total number of bytes, excluding the trailing '\0', that would have
been written.
Based on the approach taken to a similar problem in
commit 54b909436ede ("rtc: fix snprintf() checking in is_rtc_hctosys()")
Flagged by gcc-13 W=1 builds as:
.../otx2_pf.c:1933:58: warning: 'snprintf' output may be truncated before the last format character [-Wformat-truncation=]
1933 | snprintf(irq_name, NAME_SIZE, "%s-rxtx-%d", pf->netdev->name,
| ^
.../otx2_pf.c:1933:17: note: 'snprintf' output between 8 and 33 bytes into a destination of size 32
