Introduce neveraudit types i.e. types that should never trigger
audit messages. This allows the AVC to skip all audit-related
processing for such types. Note that neveraudit differs from
dontaudit not only wrt being applied for all checks with a given
source type but also in that it disables all auditing, not just
permission denials.
When a type is both a permissive type and a neveraudit type,
the security server can short-circuit the security_compute_av()
logic, allowing all permissions and not auditing any permissions.
This change just introduces the basic support but does not yet
further optimize the AVC or hook function logic when a type
is both a permissive type and a dontaudit type.

List both CPU supply regulators which drive the little and big CPU
clusters, respectively, so that cpufreq can pick them up.
Without this patch the cpufreq governor attempts to raise the big CPU
frequency under high load, while its supply voltage stays at 850000 uV.
This causes system instability and, in my case, random reboots.
With this patch, supply voltages are adjusted in step with frequency
changes from 700000-737000 uV in idle to 950000 uV under full load,
and the system appears to be stable.
While at this, list all CPU supplies for completeness.

ArmSoM Sige5 uses a soldered-on WiFi/BT module with WiFi on SDIO and BT
on UART. However, board v1.1 uses a Realtek based BL-M8852BS2, while
v1.2 uses a Broadcom based BW3752-50B1. They use the same pins and
controllers, but require different DT properties to enable.
Thankfully, the WiFi part at least works without explicitly listing it in
the device tree, albeit without OOB interrupt functionality.
Add required device tree nodes that do not depend on the board version so
that at least the WiFi module can appear on the SDIO bus.
WiFi OOB interrupt and Bluetooth function support are not enabled here, as
they require module specific properties.

So far, a vIOMMU object has been allocated by IOMMU driver and initialized
with the driver-level structure, before it returns to the iommufd core for
core-level structure initialization. It has been requiring iommufd core to
expose some core structure/helpers in its driver.c file, which result in a
size increase of this driver module.
Meanwhile, IOMMU drivers are now requiring more vIOMMU-base structures for
some advanced feature, such as the existing vDEVICE and a future HW_QUEUE.
Initializing a core-structure later than driver-structure gives for-driver
helpers some trouble, when they are used by IOMMU driver assuming that the
new structure (including core) are fully initialized, for example:
core: viommu = ops->viommu_alloc();
driver: // my_viommu is successfully allocated
driver: my_viommu = iommufd_viommu_alloc(...);
driver: // This may crash if it reads viommu->ictx
driver: new = iommufd_new_viommu_helper(my_viommu->core ...);
core: viommu->ictx = ucmd->ictx;
core: ...
To ease such a condition, allow the IOMMU driver to report the size of its
vIOMMU structure, let the core allocate a vIOMMU object and initialize the
core-level structure first, and then hand it over the driver to initialize
its driver-level structure.
Thus, this requires two new iommu ops, get_viommu_size and viommu_init, so
iommufd core can communicate with drivers to replace the viommu_alloc op:
core: viommu = ops->get_viommu_size();
driver: return VIOMMU_STRUCT_SIZE();
core: viommu->ictx = ucmd->ictx; // and others
core: rc = ops->viommu_init();
driver: // This is safe now as viommu->ictx is inited
driver: new = iommufd_new_viommu_helper(my_viommu->core ...);
core: ...
This also adds a VIOMMU_STRUCT_SIZE macro, for drivers to use, which would
statically sanitize the driver structure.

Merge slot clock support for PCI slots, which is a depdendency for
replacing the ad-hoc description of the split PCIe clock on Sparrow Hawk
by a proper hardware description.
The external RTC clock is populated on the RZ/N1D module, so describe it
and add a reference to the RTC node.

The Renesas RZ/V2N (R9A09G056) SoC features a single-channel USB2.0
interface with host and peripheral (function) support.
Add the ECHI, OHCI, USB2.0 PHY and reset control nodes for USB2.0
channel in R9A09G056 SoC DTSI.

Ensure only valid pins are configured by validating pin mappings before
setting the mux function.
Rename rzg2l_validate_gpio_pin() to rzg2l_validate_pin() to reflect its
broader purpose validating both GPIO pins and muxed pins. This helps
avoid invalid configurations.

requires adding support for a number of new FW commands so
it's quite large in terms of LoC. The rest is relatively small.
Current release - fix to a fix:
- ptp: fix breakage after ptp_vclock_in_use() rework
Current release - regressions:
- openvswitch: allocate struct ovs_pcpu_storage dynamically, static
allocation may exhaust module loader limit on smaller systems
Previous releases - regressions:
- tcp: fix tcp_packet_delayed() for peers with no selective ACK support
Previous releases - always broken:
- wifi: ath12k: don't activate more links than firmware supports
- tcp: make sure sockets open via passive TFO have valid NAPI ID
- eth: bnxt_en: update MRU and RSS table of RSS contexts on queue reset,
prevent Rx queues from silently hanging after queue reset
- NFC: uart: set tty->disc_data only in success path
