gpio updates for v6.15-rc1
GPIO core:
- add sanitization of return values of GPIO provider callbacks so that invalid
ones don't get propagated to user-space
- add new variants of the line setter callbacks for GPIO providers that return
an integer and allow to indicate driver errors to the GPIO core
- change the interface of all gpiod_set_value() variants to return an integer
thus becoming able to indicate failures in the underlying layer to callers
- drop unneeded ERR_CAST in gpiolib-acpi
- use for_each_if() where applicable
- provide gpiod_multi_set_value_cansleep() as a new, simpler interface to
gpiod_set_array_value_cansleep() and use it across several drivers treewide
- reduce the number of atomic reads of the descriptor flags in gpiolib debugfs
code
- simplify for_each_hwgpio_in_range() and for_each_requested_gpio_in_range()
- add support for three-cell GPIO specifiers in GPIO OF code
- don't build HTE (hardware timestamp engine) GPIO code with the HTE subsystem
disabled in Kconfig
- unduplicate calls to gpiod_direction_input_nonotify()
- rework the handling of the valid_mask property of GPIO chips: don't allow
drivers to set it as it should only be handled by GPIO core and start
actually enforcing it in GPIO core for *all* drivers, not only the ones
implementing a custom request() callback
- get the `ngpios` property from the fwnode of the GPIO chip, not its device in
order to handle multi-bank GPIO chips
Driver improvements:
- convert a part of the GPIO drivers under drivers/gpio/ to using the new value
setter callbacks
- convert several drivers to using automatic lock guards from cleanup.h
- allow building gpio-bt8xx with COMPILE_TEST=y
- refactor gpio-74x164 (use devres, cleanup helpers, __counted_by() and bits.h
macros)
- refactor gpio-latch (use generic device properties, lock guards and some
local variables for better readability)
- refactor gpio-xilinx (improve the usage of the bitmap API)
- support multiple virtual GPIO controller instances in gpio-virtio
- allow gpio-regmap to use the standard `ngpios` property from GPIOLIB
- factor out the common code for synchronous probing of virtual GPIO devices
into its own library
- use str_enable_disable(), str_high_low() and other string helpers where
applicable
- extend the gpio-mmio abstraction layer to allow calling into the pinctrl
back-end when setting direction
- convert gpio-vf610 to using the gpio-mmio library
- use more devres in gpio-adnp
- add support for reset-gpios in gpio-pcf857x
- add support for more models to gpio-loongson-64bit
DT bindings:
- add new compatibles to gpio-vf610 and gpio-loongson
- add missing gpio-ranges property to gpio-mvebu
- add reset-gpios to nxp,pcf8575
- enable gpio-hog parsing in ast2400-gpio
Misc:
- coding style improvements
- kerneldoc fixes
- includes reordering
- updates to the TODO list

Pull gpio updates from Bartosz Golaszewski:
"There are no new drivers this time but several changes to the core
GPIO framework and various driver updates.
This release cycle, we're starting a relatively straightforward but
tedious rework of the GPIO consumer API: for historical reasons, the
gpiod_set_value() variants would return void. Not only that but the
GPIO provider interface does not even allow drivers to return a value
to GPIO core. This is because initial GPIO controllers would be MMIO
based and could not fail. We've had I2C, SPI and USB controllers for
years too but no way of indicating failures to callers.
This changes the consumer interface, adds new provider callbacks and
starts converting the drivers under drivers/gpio/ to using them. Once
this gets upstream, we'll keep on converting GPIO drivers that live
elsewhere and once there are no more users of the old callbacks, we'll
remove them and rename the new ones to the previous name. I imagine
the last step would happen in one sweeping change like what you did
for the remove_new() -> remove() renaming.
We've also addressed an issue where invalid return values from GPIO
drivers would get propagated to user-space by adding some
GPIO-core-level sanitization. Again: not a complex change but way
overdue.
Other than that: lots of driver and core refactoring, DT-bindings
changes and some other minor changes like coding style fixes or header
reordering.
GPIO core:
- add sanitization of return values of GPIO provider callbacks so
that invalid ones don't get propagated to user-space

that return an integer and allow to indicate driver errors to the

spi: Updates for v6.15
The biggest change for SPI this release is the addition of offload
support from David Lechner, allowing the hardware to trigger SPI
transactions autonomously. The initial use case is for triggering IIO
operations but there are other applications where having the hardware
ready to go at a minimal signal is useful for synchronising with
external inputs (eg, interrupt handling) or reducing latency (eg, CAN
networking). Otherwise there's the usual fixes, improvements and
cleanups, plus support for a bunch of new devices.
- Support for offloaing support from David Lechner.
- Support for GOcontrol1 Moduline modules, Mediatek MT7988, NXP i.MX94,
Qualcomm SPI NAMD, Rockchip RK3562, Sophogo SG2044 and ST STM32 OSPI.

regulator: Updates for v6.15
This has been a very quiet release, we've got support for one device
added, another removed, and some smaller fixes and API improvements.
The main thing of note is the rework of the PCA9450 LDO5 handling:
- A rework of the handling of LDO5 on the PCA9450, this was quite wrong
in how it handled the SD_VSEL conrol and only worked for some system
designs. This includes a DTS update since there was a not quite ABI
compatible change as part of the fix.
- A devres change introducing devm_kmemdup_array() was pulled in so it
could be used with some regulator conversions to that function, this
pulled in some other devres and IIO stuff that was part of the same pull
request.
- Removal of the PCF50633 driver, the SoC for the OpenMoko platform
that used it has been removed.
- Support for the NXP PF9453.

CRC updates for 6.15
Another set of improvements to the kernel's CRC (cyclic redundancy
check) code:
- Rework the CRC64 library functions to be directly optimized, like what
I did last cycle for the CRC32 and CRC-T10DIF library functions.
- Rewrite the x86 PCLMULQDQ-optimized CRC code, and add VPCLMULQDQ
support and acceleration for crc64_be and crc64_nvme.
- Rewrite the riscv Zbc-optimized CRC code, and add acceleration for
crc_t10dif, crc64_be, and crc64_nvme.
- Remove crc_t10dif and crc64_rocksoft from the crypto API, since they
are no longer needed there.
- Rename crc64_rocksoft to crc64_nvme, as the old name was incorrect.
- Add kunit test cases for crc64_nvme and crc7.
- Eliminate redundant functions for calculating the Castagnoli CRC32,
settling on just crc32c().
- Remove unnecessary prompts from some of the CRC kconfig options.
- Further optimize the x86 crc32c code.

Rust hrtimer API for v6.15
Introduce Rust support for the `hrtimer` subsystem:
- Add a way to use the `hrtimer` subsystem from Rust. Rust code can now set up
intrusive timers without allocating when starting the timer.
- Add support for `Pin<Box<_>>`, `Arc<_>`, `Pin<&_>` and `Pin<&mut _>` as
pointer types for use with timer callbacks.
- Add support for setting clock source and timer mode.
`kernel` crate:
- Add `Arc::as_ptr` for converting an `Arc` to a raw pointer. This is a
dependency for the `hrtimer` API.
- Add `Box::into_pin` for converting a `Box<_>` into a `Pin<Box<_>>` to align
with Rust `alloc`. This is a dependency for the `hrtimer` API.

Thermal control updates for 6.15-rc1
- Delay exposing thermal zone sysfs interface to prevent user space
from accessing thermal zones that have not been completely
initialized yet (Lucas De Marchi).
- Check a pointer against NULL early in int3402_thermal_probe() to
avoid a potential NULL pointer dereference (Chenyuan Yang).
- Use kcalloc() instead of kzalloc() in some places in the thermal
control subsystem (Lukasz Luba, Ethan Carter Edwards).
- Fix a spelling mistake in a comment in the thermal core (Colin Ian
King).
- Clean up variable initialization in int340x_thermal_zone_add()
(Christophe JAILLET).

Pull thermal control updates from Rafael Wysocki:
"These include one thermal core fix for an issue leading to a NULL
pointer dereference, a similar fix for the int340x thermal driver
(even though the issue may not actually occur in practice in this
particular case), and a bunch of cleanups, mostly related to replacing
kzalloc() with kcalloc() where applicable.
Summary:
- Delay exposing thermal zone sysfs interface to prevent user space
from accessing thermal zones that have not been completely
initialized yet (Lucas De Marchi)
- Check a pointer against NULL early in int3402_thermal_probe() to
avoid a potential NULL pointer dereference (Chenyuan Yang)
- Use kcalloc() instead of kzalloc() in some places in the thermal
control subsystem (Lukasz Luba, Ethan Carter Edwards)
- Fix a spelling mistake in a comment in the thermal core (Colin Ian
King)
- Clean up variable initialization in int340x_thermal_zone_add()
(Christophe JAILLET)"

objtool, regulator: rk808: Remove potential undefined behavior in rk806_set_mode_dcdc()
If 'ctr_bit' is negative, the shift counts become negative, causing a shift of bounds and undefined behavior. Presumably that's not possible in normal operation, but the code generation isn't optimal. And undefined behavior should be avoided regardless. Improve code generation and remove the undefined behavior by converting the signed variables to unsigned. Fixes the following warning with an UBSAN kernel: vmlinux.o: warning: objtool: rk806_set_mode_dcdc() falls through to next function rk806_get_mode_dcdc() vmlinux.o: warning: objtool: .text.rk806_set_mode_dcdc: unexpected end of section Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Josh Poimboeuf <jpoimboe@kernel.org> Signed-off-by: Ingo Molnar <mingo@kernel.org> Acked-by: Mark Brown <broonie@kernel.org> Cc: Liam Girdwood <lgirdwood@gmail.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Link: https://lore.kernel.org/r/2023abcddf3f524ba478d64339996f25dc4097d2.1742852847.git.jpoimboe@kernel.org Closes: https://lore.kernel.org/oe-kbuild-all/202503182350.52KeHGD4-lkp@intel.com/ |

Dhananjay Ugwekar, Imran Shaik, zuoqian).
- Migrate some cpufreq drivers to using for_each_present_cpu() (Jacky
Bai).
- cpufreq-qcom-hw DT binding fixes (Krzysztof Kozlowski).

up calling the same writes multiple times and needlessly caching
variables through code reorganization, locking overhaul and tracing
adjustments (Mario Limonciello, Dhananjay Ugwekar).
- Make it possible to avoid enabling capacity-aware scheduling (CAS) in
the intel_pstate driver and relocate a check for out-of-band (OOB)
platform handling in it to make it detect OOB before checking HWP
availability (Rafael Wysocki).
- Fix dbs_update() to avoid inadvertent conversions of negative integer
values to unsigned int which causes CPU frequency selection to be
inaccurate in some cases when the "conservative" cpufreq governor is
in use (Jie Zhan).
- Update the handling of the most recent idle intervals in the menu
cpuidle governor to prevent useful information from being discarded
by it in some cases and improve the prediction accuracy (Rafael
Wysocki).
- Make it possible to tell the intel_idle driver to ignore its built-in
table of idle states for the given processor, clean up the handling
of auto-demotion disabling on Baytrail and Cherrytrail chips in it,
and update its MAINTAINERS entry (David Arcari, Artem Bityutskiy,
Rafael Wysocki).
- Make some cpuidle drivers use for_each_present_cpu() instead of
for_each_possible_cpu() during initialization to avoid issues
occurring when nosmp or maxcpus=0 are used (Jacky Bai).

- Use kfree_rcu() to simplify the handling of runtime Energy Model
updates (Li RongQing).
- Add an entry for the Energy Model framework to MAINTAINERS as
properly maintained (Lukasz Luba).
- Address RCU-related sparse warnings in the Energy Model code (Rafael
Wysocki).
- Remove ENERGY_MODEL dependency on SMP and allow it to be selected
when DEVFREQ is set without CPUFREQ so it can be used on a wider
range of systems (Jeson Gao).
- Unify error handling during runtime suspend and runtime resume in the
core to help drivers to implement more consistent runtime PM error
handling (Rafael Wysocki).
- Drop a redundant check from pm_runtime_force_resume() and rearrange
documentation related to __pm_runtime_disable() (Rafael Wysocki).
- Rework the handling of the "smart suspend" driver flag in the PM core
to avoid issues hat may occur when drivers using it depend on some
other drivers and clean up the related PM core code (Rafael Wysocki,
Colin Ian King).
- Fix the handling of devices with the power.direct_complete flag set
if device_suspend() returns an error for at least one device to avoid
situations in which some of them may not be resumed (Rafael Wysocki).
- Use mutex_trylock() in hibernate_compressor_param_set() to avoid a
possible deadlock that may occur if the "compressor" hibernation
module parameter is accessed during the registration of a new
ieee80211 device (Lizhi Xu).

Uytterhoeven).
- Update the cpupower utility to fix lib version-ing in it and memory
leaks in error legs, remove hard-coded values, and implement CPU
physical core querying (Thomas Renninger, John B. Wyatt IV, Shuah
Khan, Yiwei Lin, Zhongqiu Han).

Pull power management updates from Rafael Wysocki:
"These are dominated by cpufreq updates which in turn are dominated by
updates related to boost support in the core and drivers and
amd-pstate driver optimizations.
Apart from the above, there are some cpuidle updates including a
rework of the most recent idle intervals handling in the venerable
menu governor that leads to significant improvements in some
performance benchmarks, as the governor is now more likely to predict
a shorter idle duration in some cases, and there are updates of the
core device power management code, mostly related to system suspend
and resume, that should help to avoid potential issues arising when
the drivers of devices depending on one another want to use different
optimizations.

including removal of some unused code.

objtool, ASoC: codecs: wcd934x: Remove potential undefined behavior in wcd934x_slim_irq_handler()
If 'port_id' is negative, the shift counts in wcd934x_slim_irq_handler() also become negative, resulting in undefined behavior due to shift out of bounds. If I'm reading the code correctly, that appears to be not possible, but with KCOV enabled, Clang's range analysis isn't always able to determine that and generates undefined behavior. As a result the code generation isn't optimal, and undefined behavior should be avoided regardless. Improve code generation and remove the undefined behavior by converting the signed variables to unsigned.

In cyapa_update_fw_store(), if 'count' is zero, the write to fw_name[count-1] underflows the array.

tracing: Fix synth event printk format for str fields
The printk format for synth event uses "%.*s" to print string fields,
but then only passes the pointer part as var arg.
Replace %.*s with %s as the C string is guaranteed to be null-terminated.
The output in print fmt should never have been updated as __get_str()
handles the string limit because it can access the length of the string in
the string meta data that is saved in the ring buffer.

Andy Shevchenko says: ==================== net: usb: asix: ax88772: Fix potential string cut The agreement and also PHY_MAX_ADDR limit suggest that the PHY address can't occupy more than two hex digits. In some cases GCC complains about potential string cut. In course of fixing this, introduce the PHY_ID_SIZE predefined constant to make it easier for the users to know the bare minimum for the buffer that holds PHY ID string (patch 1).

net: usb: asix: ax88772: Increase phy_name size
GCC compiler (Debian 14.2.0-17) is not happy about printing into a too short buffer (when build with `make W=1`): drivers/net/usb/ax88172a.c:311:9: note: ‘snprintf’ output between 4 and 66 bytes into a destination of size 20 Indeed, the buffer size is chosen based on some assumptions, while in general the assigned name might not fit. Increase the buffer size to cover the minimum required one. With that, change snprintf() to use sizeof() instead of the hard coded value. While at it, make sure that the PHY address is not bigger than the allowed maximum.

net: phy: Introduce PHY_ID_SIZE — minimum size for PHY ID string
The PHY_ID_FMT defines the format specifier "%s:%02x" to form the PHY ID string, where the maximum of the first part is defined in MII_BUS_ID_SIZE, including NUL terminator, and the second part is implied to be 3 as the maximum address is limited to 32, meaning that 2 hex digits is more than enough, plus ':' (colon) delimiter. However, some drivers, which are using PHY_ID_FMT, customise buffer size and do that incorrectly. Introduce a new constant PHY_ID_SIZE that makes the minimum required size explicit, so drivers are encouraged to use it.

x86/mm/pat: Fix VM_PAT handling when fork() fails in copy_page_range()
If track_pfn_copy() fails, we already added the dst VMA to the maple tree. As fork() fails, we'll cleanup the maple tree, and stumble over the dst VMA for which we neither performed any reservation nor copied any page tables. Consequently untrack_pfn() will see VM_PAT and try obtaining the PAT information from the page table -- which fails because the page table was not copied. The easiest fix would be to simply clear the VM_PAT flag of the dst VMA if track_pfn_copy() fails. However, the whole thing is about "simply" clearing the VM_PAT flag is shaky as well: if we passed track_pfn_copy() and performed a reservation, but copying the page tables fails, we'll simply clear the VM_PAT flag, not properly undoing the reservation ... which is also wrong. So let's fix it properly: set the VM_PAT flag only if the reservation succeeded (leaving it clear initially), and undo the reservation if anything goes wrong while copying the page tables: clearing the VM_PAT flag after undoing the reservation. Note that any copied page table entries will get zapped when the VMA will get removed later, after copy_page_range() succeeded; as VM_PAT is not set then, we won't try cleaning VM_PAT up once more and untrack_pfn() will be happy. Note that leaving these page tables in place without a reservation is not a problem, as we are aborting fork(); this process will never run. A reproducer can trigger this usually at the first try: https://gitlab.com/davidhildenbrand/scratchspace/-/raw/main/reproducers/pat_fork.c WARNING: CPU: 26 PID: 11650 at arch/x86/mm/pat/memtype.c:983 get_pat_info+0xf6/0x110 Modules linked in: ...

ARM:
* Nested virtualization support for VGICv3, giving the nested
hypervisor control of the VGIC hardware when running an L2 VM
* Removal of 'late' nested virtualization feature register masking,
making the supported feature set directly visible to userspace
* Support for emulating FEAT_PMUv3 on Apple silicon, taking advantage
of an IMPLEMENTATION DEFINED trap that covers all PMUv3 registers
* Paravirtual interface for discovering the set of CPU implementations
where a VM may run, addressing a longstanding issue of guest CPU
errata awareness in big-little systems and cross-implementation VM
migration
* Userspace control of the registers responsible for identifying a
particular CPU implementation (MIDR_EL1, REVIDR_EL1, AIDR_EL1),
allowing VMs to be migrated cross-implementation
* pKVM updates, including support for tracking stage-2 page table
allocations in the protected hypervisor in the 'SecPageTable' stat
* Fixes to vPMU, ensuring that userspace updates to the vPMU after
KVM_RUN are reflected into the backing perf events
LoongArch:
* Remove unnecessary header include path
* Assume constant PGD during VM context switch
* Add perf events support for guest VM
RISC-V:
* Disable the kernel perf counter during configure
* KVM selftests improvements for PMU
* Fix warning at the time of KVM module removal
x86:
* Add support for aging of SPTEs without holding mmu_lock. Not taking mmu_lock
allows multiple aging actions to run in parallel, and more importantly avoids
stalling vCPUs. This includes an implementation of per-rmap-entry locking;
aging the gfn is done with only a per-rmap single-bin spinlock taken, whereas
locking an rmap for write requires taking both the per-rmap spinlock and
the mmu_lock.
Note that this decreases slightly the accuracy of accessed-page information,
because changes to the SPTE outside aging might not use atomic operations
even if they could race against a clear of the Accessed bit. This is
deliberate because KVM and mm/ tolerate false positives/negatives for
accessed information, and testing has shown that reducing the latency of
aging is far more beneficial to overall system performance than providing
"perfect" young/old information.
* Defer runtime CPUID updates until KVM emulates a CPUID instruction, to
coalesce updates when multiple pieces of vCPU state are changing, e.g. as
part of a nested transition.
* Fix a variety of nested emulation bugs, and add VMX support for synthesizing
nested VM-Exit on interception (instead of injecting #UD into L2).
* Drop "support" for async page faults for protected guests that do not set
SEND_ALWAYS (i.e. that only want async page faults at CPL3)
* Bring a bit of sanity to x86's VM teardown code, which has accumulated
a lot of cruft over the years. Particularly, destroy vCPUs before
the MMU, despite the latter being a VM-wide operation.
* Add common secure TSC infrastructure for use within SNP and in the
future TDX
* Block KVM_CAP_SYNC_REGS if guest state is protected. It does not make
sense to use the capability if the relevant registers are not
available for reading or writing.
* Don't take kvm->lock when iterating over vCPUs in the suspend notifier to
fix a largely theoretical deadlock.
* Use the vCPU's actual Xen PV clock information when starting the Xen timer,
as the cached state in arch.hv_clock can be stale/bogus.
* Fix a bug where KVM could bleed PVCLOCK_GUEST_STOPPED across different
PV clocks; restrict PVCLOCK_GUEST_STOPPED to kvmclock, as KVM's suspend
notifier only accounts for kvmclock, and there's no evidence that the
flag is actually supported by Xen guests.
* Clean up the per-vCPU "cache" of its reference pvclock, and instead only
track the vCPU's TSC scaling (multipler+shift) metadata (which is moderately
expensive to compute, and rarely changes for modern setups).
* Don't write to the Xen hypercall page on MSR writes that are initiated by
the host (userspace or KVM) to fix a class of bugs where KVM can write to
guest memory at unexpected times, e.g. during vCPU creation if userspace has
set the Xen hypercall MSR index to collide with an MSR that KVM emulates.
* Restrict the Xen hypercall MSR index to the unofficial synthetic range to
reduce the set of possible collisions with MSRs that are emulated by KVM
(collisions can still happen as KVM emulates Hyper-V MSRs, which also reside
in the synthetic range).
* Clean up and optimize KVM's handling of Xen MSR writes and xen_hvm_config.
* Update Xen TSC leaves during CPUID emulation instead of modifying the CPUID
entries when updating PV clocks; there is no guarantee PV clocks will be
updated between TSC frequency changes and CPUID emulation, and guest reads
of the TSC leaves should be rare, i.e. are not a hot path.
x86 (Intel):
* Fix a bug where KVM unnecessarily reads XFD_ERR from hardware and thus
modifies the vCPU's XFD_ERR on a #NM due to CR0.TS=1.
* Pass XFD_ERR as the payload when injecting #NM, as a preparatory step
for upcoming FRED virtualization support.
* Decouple the EPT entry RWX protection bit macros from the EPT Violation
bits, both as a general cleanup and in anticipation of adding support for
emulating Mode-Based Execution Control (MBEC).
* Reject KVM_RUN if userspace manages to gain control and stuff invalid guest
state while KVM is in the middle of emulating nested VM-Enter.
* Add a macro to handle KVM's sanity checks on entry/exit VMCS control pairs
in anticipation of adding sanity checks for secondary exit controls (the
primary field is out of bits).
x86 (AMD):
* Ensure the PSP driver is initialized when both the PSP and KVM modules are
built-in (the initcall framework doesn't handle dependencies).
* Use long-term pins when registering encrypted memory regions, so that the
pages are migrated out of MIGRATE_CMA/ZONE_MOVABLE and don't lead to
excessive fragmentation.
* Add macros and helpers for setting GHCB return/error codes.
* Add support for Idle HLT interception, which elides interception if the vCPU
has a pending, unmasked virtual IRQ when HLT is executed.
* Fix a bug in INVPCID emulation where KVM fails to check for a non-canonical
address.
* Don't attempt VMRUN for SEV-ES+ guests if the vCPU's VMSA is invalid, e.g.
because the vCPU was "destroyed" via SNP's AP Creation hypercall.
* Reject SNP AP Creation if the requested SEV features for the vCPU don't
match the VM's configured set of features.
Selftests:
* Fix again the Intel PMU counters test; add a data load and do CLFLUSH{OPT} on the data
instead of executing code. The theory is that modern Intel CPUs have
learned new code prefetching tricks that bypass the PMU counters.
* Fix a flaw in the Intel PMU counters test where it asserts that an event is
counting correctly without actually knowing what the event counts on the
underlying hardware.
* Fix a variety of flaws, bugs, and false failures/passes dirty_log_test, and
improve its coverage by collecting all dirty entries on each iteration.
* Fix a few minor bugs related to handling of stats FDs.
* Add infrastructure to make vCPU and VM stats FDs available to tests by
default (open the FDs during VM/vCPU creation).
* Relax an assertion on the number of HLT exits in the xAPIC IPI test when
running on a CPU that supports AMD's Idle HLT (which elides interception of
HLT if a virtual IRQ is pending and unmasked).

net: libwx: fix Tx descriptor content for some tunnel packets
The length of skb header was incorrectly calculated when transmit a tunnel
packet with outer IPv6 extension header, or a IP over IP packet which has
inner IPv6 header. Thus the correct Tx context descriptor cannot be
composed, resulting in Tx ring hang.

atm: Fix NULL pointer dereference
When MPOA_cache_impos_rcvd() receives the msg, it can trigger
Null Pointer Dereference Vulnerability if both entry and
holding_time are NULL. Because there is only for the situation
where entry is NULL and holding_time exists, it can be passed
when both entry and holding_time are NULL. If these are NULL,
the entry will be passd to eg_cache_put() as parameter and
it is referenced by entry->use code in it.

net: tn40xx: add pci-id of the aqr105-based Tehuti TN4010 cards
Add the PCI-ID of the AQR105-based Tehuti TN4010 cards to allow loading of the tn40xx driver on these cards. Here, I chose the detailed definition with the subvendor ID similar to the QT2025 cards with the PCI-ID TEHUTI:0x4022, because there is a card with an AQ2104 hiding amongst the AQR105 cards, and they all come with the same PCI-ID (TEHUTI:0x4025). But the AQ2104 is currently not supported.

net: tn40xx: prepare tn40xx driver to find phy of the TN9510 card
Prepare the tn40xx driver to load for Tehuti TN9510 cards, which require bit 3 in the register TN40_REG_MDIO_CMD_STAT to be set. The function of bit 3 is unclear, but may have something to do with the length of the preamble in the MDIO communication. If bit 3 is not set, the PHY will not be found when performing a scan for PHYs. Use the available tn40_mdio_set_speed function which includes setting bit 3. Just move the function to before the devm_mdio_register function, which scans the mdio bus for PHYs.

net: tn40xx: create swnode for mdio and aqr105 phy and add to mdiobus
In case of an AQR105-based device, create a software node for the mdio function, with a child node for the Aquantia AQR105 PHY, providing a firmware-name (and a bit more, which may be used for future checks) to allow the PHY to load a MAC specific firmware from the file system. The name of the PHY software node follows the naming convention suggested in the patch for the mdiobus_scan function (in the same patch series).

net: phy: aquantia: add essential functions to aqr105 driver
This patch makes functions that were provided for aqr107 applicable to aqr105, or replaces generic functions with specific ones. Since the aqr105 was introduced before NBASE-T was defined (or 802.3bz), there are a number of vendor specific registers involved in the definition of the advertisement, in auto-negotiation and in the setting of the speed. The functions have been written following the downstream driver for TN4010 cards with aqr105 PHY, and use code from aqr107 functions wherever it seemed to make sense.

net: phy: Add swnode support to mdiobus_scan
This patch will allow to use a swnode/fwnode defined for a phy_device. The MDIO bus (mii_bus) needs to contain nodes for the PHY devices, named "ethernet-phy@i", with i being the MDIO address (0 .. PHY_MAX_ADDR - 1). The fwnode is only attached to the phy_device if there isn't already an fwnode attached. fwnode_get_named_child_node will increase the usage counter of the fwnode. However, no new code is needed to decrease the counter again, since this is already implemented in the phy_device_release function.

gve: add XDP DROP and PASS support for DQ
This patch adds support for running XDP programs on DQ, along with rudimentary processing for XDP_DROP and XDP_PASS. These actions require very limited driver functionality when it comes to processing an XDP buffer, so currently if the XDP action is not XDP_PASS, the packet is dropped and stats are updated.
