Even though dummy device doesn't really need an instance lock,
a lot of selftests use dummy so it's useful to have extra
expose to the instance lock on NIPA. Request the instance/ops
locking.

In order to exercise and verify notifiers' locking assumptions,
register dummy notifiers (via register_netdevice_notifier_dev_net).
Share notifier event handler that enforces the assumptions with
lock_debug.c (rename and export rtnl_net_debug_event as
netdev_debug_event). Add ops lock asserts to netdev_debug_event.

Pull RTC updates from Alexandre Belloni:
"We see a net reduction of the number of lines of code thanks to the
removal of a now unused driver and a testing tool that is not used
anymore. Apart from this, the max31335 driver gets support for a new
part number and pm8xxx gets UEFI support.
Core:
- setdate is removed as it has better replacements
- skip alarms with a second resolution when we know the RTC doesn't
support those.
Subsystem:
- remove unnecessary private struct members
- use devm_pm_set_wake_irq were relevant
Drivers:
- ds1307: stop disabling alarms on probe for DS1337, DS1339, DS1341

- max31335: add max31331 support

Dev pointer in airoha_ppe_foe_entry_prepare routine is not strictly
a device allocated by airoha_eth driver since it is an egress device
and the flowtable can contain even wlan, pppoe or vlan devices. E.g:
flowtable ft {
hook ingress priority filter
devices = { eth1, lan1, lan2, lan3, lan4, wlan0 }
flags offload ^
|
"not allocated by airoha_eth" --
}
In this case airoha_get_dsa_port() will just return the original device
pointer and we can't assume netdev priv pointer points to an
airoha_gdm_port struct.
Fix the issue validating egress gdm port in airoha_ppe_foe_entry_prepare
routine before accessing net_device priv pointer.

The mv88e6xxx has an internal PPU that polls PHY state. If we want to
access the internal PHYs, we need to disable the PPU first. Because
that is a slow operation, a 10ms timer is used to re-enable it,
canceled with every access, so bulk operations effectively only
disable it once and re-enable it some 10ms after the last access.
If a PHY is accessed and then the mv88e6xxx module is removed before
the 10ms are up, the PPU re-enable ends up accessing a dangling pointer.
This especially affects probing during bootup. The MDIO bus and PHY
registration may succeed, but registration with the DSA framework
may fail later on (e.g. because the CPU port depends on another,
very slow device that isn't done probing yet, returning -EPROBE_DEFER).
In this case, probe() fails, but the MDIO subsystem may already have
accessed the MIDO bus or PHYs, arming the timer.
This is fixed as follows:
- If probe fails after mv88e6xxx_phy_init(), make sure we also call
mv88e6xxx_phy_destroy() before returning
- In mv88e6xxx_remove(), make sure we do the teardown in the correct
order, calling mv88e6xxx_phy_destroy() after unregistering the
switch device.
- In mv88e6xxx_phy_destroy(), destroy both the timer and the work item
that the timer might schedule, synchronously waiting in case one of
the callbacks already fired and destroying the timer first, before
waiting for the work item.
- Access to the PPU is guarded by a mutex, the worker acquires it
with a mutex_trylock(), not proceeding with the expensive shutdown
if that fails. We grab the mutex in mv88e6xxx_phy_destroy() to make
sure the slow PPU shutdown is already done or won't even enter, when
we wait for the work item.

When queue is being reset, callbacks of mgmt_ops are called by
netdev_nl_bind_rx_doit().
The netdev_nl_bind_rx_doit() first acquires netdev_lock() and then calls
callbacks.
So, mgmt_ops callbacks should not acquire netdev_lock() internaly.
The bnxt_queue_{start | stop}() calls napi_{enable | disable}() but they
internally acquire netdev_lock().
So, deadlock occurs.
To avoid deadlock, napi_{enable | disable}_locked() should be used
instead.

The ufs device JEDEC specification version 4.1 adds support for the
device level exception events. To support this new device level
exception feature, expose two new sysfs nodes below to provide the user
space access to the device level exception information.
/sys/bus/platform/drivers/ufshcd/*/device_lvl_exception_count
/sys/bus/platform/drivers/ufshcd/*/device_lvl_exception_id
The device_lvl_exception_count sysfs node reports the number of device
level exceptions that have occurred since the last time this variable is
reset. Writing a value of 0 will reset it. The device_lvl_exception_id
reports the exception ID which is the qDeviceLevelExceptionID attribute
of the device JEDEC specifications version 4.1 and later. The user space
application can query these sysfs nodes to get more information about
the device level exception.

The smartpqi driver checks the reset_devices variable to determine
whether special adjustments need to be made for kdump. This has the
effect that after a regular kexec reboot, some driver parameters such as
max_transfer_size are much lower than usual. More importantly, kexec
reboot tests have revealed memory corruption caused by the driver log
being written to system memory after a kexec.
Fix this by testing is_kdump_kernel() rather than reset_devices where
appropriate.

Peter Griffin <peter.griffin@linaro.org> says:
Hi folks,
This series fixes several stability issues with the upstream ufs-exynos
driver, specifically for the gs101 SoC found in Pixel 6.
The main fix is regarding the IO cache coherency setting and ensuring
that it is correctly applied depending on if the dma-coherent property
is specified in device tree. This fixes the UFS stability issues on gs101
and I would imagine will also fix issues on exynosauto platform that
seems to have similar iocc shareability bits.
Additionally the phy reference counting is fixed which allows module
load/unload to work reliably and keeps the phy state machine in sync
with the controller glue driver.
regards,
Peter

ufshcd_pltfrm_remove() calls ufshcd_remove(hba) which in turn calls

By moving the phy_power_off() and phy_exit() calls to the newly created

ufshcd_hba_exit() turns off the regulators. This is also similar flow to
the ufs-qcom driver.

Protect the parser TCAM/SRAM memory, and the cached (shadow) SRAM
information, from concurrent modifications.
Both the TCAM and SRAM tables are indirectly accessed by configuring
an index register that selects the row to read or write to. This means
that operations must be atomic in order to, e.g., avoid spreading
writes across multiple rows. Since the shadow SRAM array is used to
find free rows in the hardware table, it must also be protected in
order to avoid TOCTOU errors where multiple cores allocate the same
row.
This issue was detected in a situation where `mvpp2_set_rx_mode()` ran
concurrently on two CPUs. In this particular case the
MVPP2_PE_MAC_UC_PROMISCUOUS entry was corrupted, causing the
classifier unit to drop all incoming unicast - indicated by the
`rx_classifier_drops` counter.

With CONFIG_COMPILE_TEST && !CONFIG_HAVE_CLK, pwm_mediatek_config() has a
divide-by-zero in the following line:
do_div(resolution, clk_get_rate(pc->clk_pwms[pwm->hwpwm]));
due to the fact that the !CONFIG_HAVE_CLK version of clk_get_rate()
returns zero.
This is presumably just a theoretical problem: COMPILE_TEST overrides
the dependency on RALINK which would select COMMON_CLK. Regardless it's
a good idea to check for the error explicitly to avoid divide-by-zero.
Fixes the following warning:
drivers/pwm/pwm-mediatek.o: warning: objtool: .text: unexpected end of section

With SRIOV enabled, idpf ends up calling into idpf_remove() twice.
First via idpf_shutdown() and then again when idpf_remove() calls into
sriov_disable(), because the VF devices use the idpf driver, hence the
same remove routine. When that happens, it is possible for the adapter
to be NULL from the first call to idpf_remove(), leading to a NULL
pointer dereference.
echo 1 > /sys/class/net/<netif>/device/sriov_numvfs
reboot

Replace the direct idpf_remove() call in idpf_shutdown() with
idpf_vc_core_deinit() and idpf_deinit_dflt_mbx(), which perform
the bulk of the cleanup, such as stopping the init task, freeing IRQs,
destroying the vports and freeing the mailbox. This avoids the calls to
sriov_disable() in addition to a small netdev cleanup, and destroying
workqueues, which don't seem to be required on shutdown.
