Document support for the I2C Bus Interface (RIIC) found on the Renesas
RZ/V2N (R9A09G056) SoC. The RIIC IP is identical to that on RZ/V2H(P),
so `renesas,riic-r9a09g057` will be used as a fallback compatible,
enabling reuse of the existing driver without changes.

The documentation on testing static functions using the KUnit macros
VISIBLE_IF_KUNIT and EXPORT_SYMBOL_IF_KUNIT is lacking clarity and
missing key steps in the example. This has caused bugs and confusion
among developers.
Improve wording of description and add missing steps to the example.
This entails adding the "#include <kunit/visibility.h>" line and the
"MODULE_IMPORT_NS(EXPORTED_FOR_KUNIT_TESTING);" line. Both of which were
missing from the original example and key to exposing static functions.

Add support for KVM_CAP_X86_BUS_LOCK_EXIT on SVM CPUs with Bus Lock
Threshold, which is close enough to VMX's Bus Lock Detection VM-Exit to
allow reusing KVM_CAP_X86_BUS_LOCK_EXIT.
The biggest difference between the two features is that Threshold is
fault-like, whereas Detection is trap-like. To allow the guest to make
forward progress, Threshold provides a per-VMCB counter which is
decremented every time a bus lock occurs, and a VM-Exit is triggered if
and only if the counter is '0'.
To provide Detection-like semantics, initialize the counter to '0', i.e.
exit on every bus lock, and when re-executing the guilty instruction, set
the counter to '1' to effectively step past the instruction.
Note, in the unlikely scenario that re-executing the instruction doesn't
trigger a bus lock, e.g. because the guest has changed memory types or
patched the guilty instruction, the bus lock counter will be left at '1',
i.e. the guest will be able to do a bus lock on a different instruction.
In a perfect world, KVM would ensure the counter is '0' if the guest has
made forward progress, e.g. if RIP has changed. But trying to close that
hole would incur non-trivial complexity, for marginal benefit; the intent
of KVM_CAP_X86_BUS_LOCK_EXIT is to allow userspace rate-limit bus locks,
not to allow for precise detection of problematic guest code. And, it's
simply not feasible to fully close the hole, e.g. if an interrupt arrives
before the original instruction can re-execute, the guest could step past
a different bus lock.

Introduce 'firmware-name' property to allow end-users and/or integrators
to decide which usecase-specific firmware to run on the WCN7850 platform.
This is necessary due to resource limitations such as memory capacity and
CPU capability, or performance and power optimization for different
application scenarios.
Two firmwares are supported: 'WCN7850/hw2.0' and 'WCN7850/hw2.0/ncm825'.
The former is the default firmware, suitable for most WiFi 7 STA
functions. The latter adds support for commercial-quality SAP and
optimizes power consumption for IoT applications.

Update the documentation to reflect the migration of the following
architectures to the centralized syscall table format:
arc, arm64, csky, hexagon, loongarch, nios2, openrisc, riscv
As of commit 3db80c999debbad ("riscv: convert to generic syscall table"),
these architectures no longer rely on include/uapi/asm-generic/unistd.h.
Instead, syscall table headers (syscall_table_{32,64}.h) are generated by
scripts/syscalltbl.sh based on entries in scripts/syscall.tbl, with ABIs
specified in arch/*/kernel/Makefile.syscalls.
For the convenience of developers working with older kernel versions, the
original documentation is fully retained, with new sections added to
cover the scripts/syscall.tbl approach.
Verified with `make htmldocs`.

Add Epoch Subsystem (EPSS) L3 provider support on SA8775P SoCs.

On AmpereOne AC04, updates to HCR_EL2 can rarely corrupt simultaneous
translations for data addresses initiated by load/store instructions.
Only instruction initiated translations are vulnerable, not translations
from prefetches for example. A DSB before the store to HCR_EL2 is
sufficient to prevent older instructions from hitting the window for
corruption, and an ISB after is sufficient to prevent younger
instructions from hitting the window for corruption.

Updates for v6.16
CI:
- uprev mesa
GPU:
- ACD (Adaptive Clock Distribution) support for X1-85. This is required
enable the higher frequencies.
- Drop fictional `address_space_size`. For some older devices, the address
space size is limited to 4GB to avoid potential 64b rollover math problems
in the fw. For these, an `ADRENO_QUIRK_4GB_VA` quirk is added. For
everyone else we get the address space size from the SMMU `ias` (input
address sizes), which is usually 48b.
- Improve robustness when GMU HFI responses time out
- Fix crash when throttling GPU immediately during boot
- Fix for rgb565_predicator on Adreno 7c3
- Remove `MODULE_FIRMWARE()`s for GPU, the GPU can load the firmware after
probe and having partial set of fw (ie. sqe+gmu but not zap) causes problems
MDSS:
- Added SAR2130P support to MDSS driver
DPU:
- Changed to use single CTL path for flushing on DPU 5.x+
- Improved SSPP allocation code to allow sharing of SSPP between planes

As SG2044 also implements an enhanced ACLINT as SG2042, add necessary

Both Intel and AMD CPUs support 5-level paging, which is expected to
become more widely adopted in the future. All major x86 Linux
distributions have the feature enabled.
Remove CONFIG_X86_5LEVEL and related #ifdeffery for it to make it more readable.

C naming info for OVPN which was added since I adjusted
the existing attrs. Also add missing reference to a header needed
for a bridge struct.

irqdomain.c's kernel-doc exists, but is not plugged into Documentation/
yet.
Before plugging it in, fix it first: irq_domain_get_irq_data() and
irq_domain_set_info() were documented twice. Identically, by both
definitions for CONFIG_IRQ_DOMAIN_HIERARCHY and !CONFIG_IRQ_DOMAIN_HIERARCHY.
Therefore, switch the second kernel-doc into an ordinary comment -- change
"/**" to simple "/*". This avoids sphinx's: WARNING: Duplicate C
declaration
Next, in commit b7b377332b96 ("irqdomain: Fix the kernel-doc and plug it
into Documentation"), irqdomain.h's (header) kernel-doc was added into
core-api/genericirq.rst. But given the amount of irqdomain functions and
structures, move all these to core-api/irq/irq-domain.rst now.
Finally, add these newly fixed irqdomain.c's (source) docs there as
well.

The irqdomain documentaion became obsolete over time. Update and extend
it a bit with respect to the current code and HW.
Most notably the doubled documentation of irq_domain (from .rst and .h)
was unified and let only in .rst. A reference link was added to .h.
Furthermore:
* Add some 'struct' keywords, so that the respective structs are
hyperlinked
* :c:member: use where appropriate to mark a member of a struct
* Rephrase some wording to improve readability/understanding

The improvements include:
* Capitals in headlines.
* Add commas: for easier reading, it is always desired to add commas
at some places in text. Like before adverbs or after fronted
sentences.
* 3rd person -> add 's' to verbs.
* End some sentences with period and start a new one. Avoid thus heavy
sentences.

Just note in the docs:
1) A PCI device as an example for shared interrupts
2) A sparse tree can be used for interrupts too
3) i8259s which have 8 pins
