Add a compatible string for the Renesas RZ/G3E SoC variants that
include a Mali-G52 GPU. These variants share the same restrictions on
interrupts, clocks, and power domains as the RZ/G2L SoC, so extend
the existing schema validation accordingly.

Pull sched_ext updates from Tejun Heo:
- More in-kernel idle CPU selection improvements. Expand topology
awareness coverage add scx_bpf_select_cpu_and() to allow more
flexibility. The idle CPU selection kfuncs can now be called from
unlocked contexts too.
- A bunch of reorganization changes to lay the foundation for multiple
hierarchical scheduler support. This isn't ready yet and the included
changes don't make meaningful behavior differences. One notable
change is replacing some static_key tests with dynamic tests as the
test results may differ depending on the scheduler instance. This
isn't expected to cause meaningful performance difference.
- Other minor and doc updates.
- There were multiple patches in for-6.15-fixes which conflicted with
changes in for-6.16. for-6.15-fixes were pulled three times into
for-6.16 to resolve the conflicts.

Pull cgroup updates from Tejun Heo:
- cgroup rstat shared the tracking tree across all controllers with the
rationale being that a cgroup which is using one resource is likely
to be using other resources at the same time (ie. if something is
allocating memory, it's probably consuming CPU cycles).
However, this turned out to not scale very well especially with memcg
using rstat for internal operations which made memcg stat read and
flush patterns substantially different from other controllers. JP
Kobryn split the rstat tree per controller.
- cgroup BPF support was hooking into cgroup init/exit paths directly.
Convert them to use a notifier chain instead so that other usages can
be added easily. The two of the patches which implement this are
mislabeled as belonging to sched_ext instead of cgroup. Sorry.
- Relatively minor cpuset updates
- Documentation updates

Users of IPE require a way to identify when and why an operation fails,
allowing them to both respond to violations of policy and be notified
of potentially malicious actions on their systems with respect to IPE.
This patch introduces a new error field to the AUDIT_IPE_POLICY_LOAD event
to log policy loading failures. Currently, IPE only logs successful policy
loads, but not failures. Tracking failures is crucial to detect malicious
attempts and ensure a complete audit trail for security events.
The new error field will capture the following error codes:
* -ENOKEY: Key used to sign the IPE policy not found in the keyring
* -ESTALE: Attempting to update an IPE policy with an older version
* -EKEYREJECTED: IPE signature verification failed
* -ENOENT: Policy was deleted while updating
* -EEXIST: Same name policy already deployed
* -ERANGE: Policy version number overflow
* -EINVAL: Policy version parsing error
* -EPERM: Insufficient permission
* -ENOMEM: Out of memory (OOM)
* -EBADMSG: Policy is invalid
Here are some examples of the updated audit record types:
AUDIT_IPE_POLICY_LOAD(1422):
audit: AUDIT1422 policy_name="Test_Policy" policy_version=0.0.1
policy_digest=sha256:84EFBA8FA71E62AE0A537FAB962F8A2BD1053964C4299DCA
92BFFF4DB82E86D3 auid=1000 ses=3 lsm=ipe res=1 errno=0
The above record shows a new policy has been successfully loaded into
the kernel with the policy name, version, and hash with the errno=0.
AUDIT_IPE_POLICY_LOAD(1422) with error:
audit: AUDIT1422 policy_name=? policy_version=? policy_digest=?
auid=1000 ses=3 lsm=ipe res=0 errno=-74
The above record shows a policy load failure due to an invalid policy
(-EBADMSG).
By adding this error field, we ensure that all policy load attempts,
whether successful or failed, are logged, providing a comprehensive
audit trail for IPE policy management.

Pull power management updates from Rafael Wysocki:
"Once again, the changes are dominated by cpufreq updates, but this
time the majority of them are cpufreq core changes, mostly related to
the introduction of policy locking guards and __free() usage, and
fixes related to boost handling.
Still, there is also a significant update of the intel_pstate driver
making it register an energy model when running on a hybrid platform
which is used for enabling energy-aware scheduling (EAS) if the driver
operates in the passive mode (and schedutil is used as the cpufreq
governor for all CPUs which is the passive mode default).
There are some amd-pstate driver updates too, for a good measure,
including the "Requested CPU Min frequency" BIOS option support and
new online/offline callbacks.
In the cpuidle space, the most significant change is the addition of a
C1 demotion on/off sysfs knob to intel_idle which should help some
users to configure their systems more precisely. There is also the
conversion of the PSCI cpuidle driver to a faux device one and there
are two small updates of cpuidle governors.
Device power management is also modified quite a bit, especially the
handling of devices with asynchronous suspend and resume enabled
during system transitions. They are now going to be handled more
asynchronously during suspend transitions and somewhat less
aggressively during resume transitions.
Apart from the above, the operating performance points (OPP) library
is now going to use mutex locking guards and scope-based cleanup
helpers and there is the usual bunch of assorted fixes and code
cleanups.
Specifics:
- Fix potential division-by-zero error in em_compute_costs() (Yaxiong
Tian)
- Fix typos in energy model documentation and example driver code
(Moon Hee Lee, Atul Kumar Pant)
- Rearrange the energy model management code and add a new function
for adjusting a CPU energy model after adjusting the capacity of
the given CPU to it (Rafael Wysocki)

guards, use __free() in policy reference counting, and clean up
core cpufreq code on top of that (Rafael Wysocki)

Kumar)
- Fix des_perf clamping with max_perf in amd_pstate_update()
(Dhananjay Ugwekar)

rename and use the existing amd_pstate_epp callbacks in it
(Dhananjay Ugwekar)

the amd-pstate driver (Dhananjay Ugwekar)
- Reset amd-pstate driver mode after running selftests (Swapnil
Sapkal)

Chancellor)

driver after registering asym capacity support (Ricardo Neri)
- Add support for enabling Energy-aware scheduling (EAS) to the
intel_pstate driver when operating in the passive mode on a hybrid
platform (Rafael Wysocki)
- Drop redundant cpus_read_lock() from store_local_boost() in the
cpufreq core (Seyediman Seyedarab)
- Replace sscanf() with kstrtouint() in the cpufreq code and use a
symbol instead of a raw number in it (Bowen Yu)
- Add support for autonomous CPU performance state selection to the
CPPC cpufreq driver (Lifeng Zheng)

reference counting (Bence Csókás)
- Remove size arguments from strscpy() calls in the hibernation core
code (Thorsten Blum)
- Adjust the handling of devices with asynchronous suspend enabled
during system suspend and resume to start resuming them immediately
after resuming their parents and to start suspending such a device
immediately after suspending its first child (Rafael Wysocki)
- Adjust messages printed during tasks freezing to avoid using
pr_cont() (Andrew Sayers, Paul Menzel)
- Clean up unnecessary usage of !! in pm_print_times_init() (Zihuan
Zhang)

Pull gpio updates from Bartosz Golaszewski:
"We have three new drivers, some refactoring in the GPIO core, lots of
various changes across many drivers, new configfs interface for the
virtual gpio-aggregator module and DT-bindings updates.
The treewide conversion of GPIO drivers to using the new value setter
callbacks is ongoing with another round of GPIO drivers updated. You
will also see these commits coming in from other subsystems as with
the relevant changes merged into mainline last cycle, I've started
converting GPIO providers located elsewhere than drivers/gpio/.
GPIO core:
- use more lock guards where applicable
- refactor GPIO ACPI code and shrink it in the process by 8%
- move GPIO ACPI quirks into a separate file
- remove unneeded #ifdef
- convert GPIO devres helpers to using devm_add_action() where
applicable which shrinks and simplifies the code
- refactor GPIO descriptor validation in GPIO consumer interfaces
- don't allow setting values on input lines in the GPIO core which
will take off the burden from GPIO drivers of checking this down
the line
- provide gpiod_is_equal() as a way of safely comparing two GPIO
descriptors (the only current user is in regulator core)
New drivers:
- add the GPIO module for the max77759 multifunction device
- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter
callbacks
- convert more drivers to making the irq_chip immutable as is
recommended by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built
with COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that
makes the setup easier for user-space than the existing
driver-level sysfs attributes and also adds more advanced
configuration features (such as referring to aggregated lines by
their original names or modifying their names as exposed by the
aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the
global GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x
- don't double-check the ngpios property in gpio-ds4520 as GPIO core
already does it
- don't double-check the number of GPIOs in gpio-imx-scu as GPIO core
already does it
- remove unused callbacks from gpio-max3191x
DT bindings:
- add device-tree bindings for max77759, spacemit,k1 and blzp1600
(new drivers added this cycle)
- document more properties for gpio-vf610 and gpio-tegra186
- document a new pca95xx variant
- fix style of examples in several GPIO DT-binding documents

- TODO list updates"

Pull documentation updates from Jonathan Corbet:
"A moderately busy cycle for documentation this time around:
- The most significant change is the replacement of the old
kernel-doc script (a monstrous collection of Perl regexes that
predates the Git era) with a Python reimplementation. That, too, is
a horrifying collection of regexes, but in a much cleaner and more
maintainable structure that integrates far better with the Sphinx
build system.
This change has been in linux-next for the full 6.15 cycle; the
small number of problems that turned up have been addressed,
seemingly to everybody's satisfaction. The Perl kernel-doc script
remains in tree (as scripts/kernel-doc.pl) and can be used with a
command-line option if need be. Unless some reason to keep it
around materializes, it will probably go away in 6.17.
Credit goes to Mauro Carvalho Chehab for doing all this work.

Pull MSI updates from Thomas Gleixner:
"Updates for the MSI subsystem (core code and PCI):
- Switch the MSI descriptor locking to lock guards
- Replace a broken and naive implementation of PCI/MSI-X control word
updates in the PCI/TPH driver with a properly serialized variant in
the PCI/MSI core code.
- Remove the MSI descriptor abuse in the SCCI/UFS/QCOM driver by
replacing the direct access to the MSI descriptors with the proper
API function calls. People will never understand that APIs exist
for a reason...
- Provide core infrastructre for the upcoming PCI endpoint library
extensions. Currently limited to ARM GICv3+, but in theory
extensible to other architectures.
- Provide a MSI domain::teardown() callback, which allows drivers to
undo the effects of the prepare() callback.
- Move the MSI domain::prepare() callback invocation to domain
creation time to avoid redundant (and in case of ARM/GIC-V3-ITS
confusing) invocations on every allocation.
In combination with the new teardown callback this removes some
ugly hacks in the GIC-V3-ITS driver, which pretended to work around
the short comings of the core code so far. With this update the
code is correct by design and implementation.
- Make the irqchip MSI library globally available, provide a MSI
parent domain creation helper and convert a bunch of (PCI/)MSI
drivers over to the modern MSI parent mechanism. This is the first
step to get rid of at least one incarnation of the three PCI/MSI
management schemes.
- The usual small cleanups and improvements"

Pull core x86 updates from Ingo Molnar:
"Boot code changes:
- A large series of changes to reorganize the x86 boot code into a
better isolated and easier to maintain base of PIC early startup
code in arch/x86/boot/startup/, by Ard Biesheuvel.
Motivation & background:
| Since commit
|
| c88d71508e36 ("x86/boot/64: Rewrite startup_64() in C")
|
| dated Jun 6 2017, we have been using C code on the boot path in a way
| that is not supported by the toolchain, i.e., to execute non-PIC C
| code from a mapping of memory that is different from the one provided
| to the linker. It should have been obvious at the time that this was a
| bad idea, given the need to sprinkle fixup_pointer() calls left and
| right to manipulate global variables (including non-pointer variables)
| without crashing.
|
| This C startup code has been expanding, and in particular, the SEV-SNP
| startup code has been expanding over the past couple of years, and
| grown many of these warts, where the C code needs to use special
| annotations or helpers to access global objects.
This tree includes the first phase of this work-in-progress x86

Pull fscrypt update from Eric Biggers:
"Add support for 'hardware-wrapped inline encryption keys' to fscrypt.
When enabled on supported platforms, this feature protects file
contents keys from certain attacks, such as cold boot attacks.
This feature uses the block layer support for wrapped keys which was
merged in 6.15. Wrapped key support has existed out-of-tree in Android
for a long time, and it's finally ready for upstream now that there is
a platform on which it works end-to-end with upstream.
Specifically, it works on the Qualcomm SM8650 HDK, using the Qualcomm
ICE (Inline Crypto Engine) and HWKM (Hardware Key Manager). The
corresponding driver support is included in the SCSI tree for 6.16.
Validation for this feature includes two new tests that were already
merged into xfstests (generic/368 and generic/369)"

KVM/arm64 updates for 6.16
* New features:
- Add large stage-2 mapping support for non-protected pKVM guests,
clawing back some performance.
- Add UBSAN support to the standalone EL2 object used in nVHE/hVHE and
protected modes.
- Enable nested virtualisation support on systems that support it
(yes, it has been a long time coming), though it is disabled by
default.
* Improvements, fixes and cleanups:
- Large rework of the way KVM tracks architecture features and links
them with the effects of control bits. This ensures correctness of
emulation (the data is automatically extracted from the published
JSON files), and helps dealing with the evolution of the
architecture.
- Significant changes to the way pKVM tracks ownership of pages,
avoiding page table walks by storing the state in the hypervisor's
vmemmap. This in turn enables the THP support described above.
- New selftest checking the pKVM ownership transition rules
- Fixes for FEAT_MTE_ASYNC being accidentally advertised to guests
even if the host didn't have it.
- Fixes for the address translation emulation, which happened to be
rather buggy in some specific contexts.
- Fixes for the PMU emulation in NV contexts, decoupling PMCR_EL0.N
from the number of counters exposed to a guest and addressing a
number of issues in the process.
- Add a new selftest for the SVE host state being corrupted by a
guest.
- Keep HCR_EL2.xMO set at all times for systems running with the
kernel at EL2, ensuring that the window for interrupts is slightly
bigger, and avoiding a pretty bad erratum on the AmpereOne HW.
- Add workaround for AmpereOne's erratum AC04_CPU_23, which suffers
from a pretty bad case of TLB corruption unless accesses to HCR_EL2
are heavily synchronised.
- Add a per-VM, per-ITS debugfs entry to dump the state of the ITS
tables in a human-friendly fashion.
- and the usual random cleanups.
