Consider a scenario where a CPU transitions from CPUHP_ONLINE to halfway
through a CPU hotunplug down to CPUHP_HRTIMERS_PREPARE, and then back to
CPUHP_ONLINE:
Since hrtimers_prepare_cpu() does not run, cpu_base.hres_active remains set
to 1 throughout. However, during a CPU unplug operation, the tick and the
clockevents are shut down at CPUHP_AP_TICK_DYING. On return to the online
state, for instance CFS incorrectly assumes that the hrtick is already
active, and the chance of the clockevent device to transition to oneshot
mode is also lost forever for the CPU, unless it goes back to a lower state
than CPUHP_HRTIMERS_PREPARE once.
This round-trip reveals another issue; cpu_base.online is not set to 1
after the transition, which appears as a WARN_ON_ONCE in enqueue_hrtimer().
Aside of that, the bulk of the per CPU state is not reset either, which
means there are dangling pointers in the worst case.
Address this by adding a corresponding startup() callback, which resets the
stale per CPU state and sets the online flag.
[ tglx: Make the new callback unconditionally available, remove the online
modification in the prepare() callback and clear the remaining
state in the starting callback instead of the prepare callback ]

Add a helper to initialize the lockdep, that is initialize the spinlock

Fix the return type of do_mount() function from long to int to match its ac
tual behavior. The function only returns int values, and all callers, inclu
ding those in fs/namespace.c and arch/alpha/kernel/osf_sys.c, already treat
the return value as int. This change improves type consistency across the
filesystem code and aligns the function signature with its existing impleme
ntation and usage.

The new ASUS ProArt 16" laptop series come with their keyboards stuck in
an Out-Of-Box-Experience mode. While in this mode most functions will
not work such as LED control or Fn key combos. The correct init sequence
is now done to disable this OOBE.
This patch addresses only the ProArt series so far and it is unknown if
there may be others, in which case a new quirk may be required.

====================
net: reduce RTNL pressure in unregister_netdevice()
One major source of RTNL contention resides in unregister_netdevice()
Due to RCU protection of various network structures, and
unregister_netdevice() being a synchronous function,
it is calling potentially slow functions while holding RTNL.
I think we can release RTNL in two points, so that three
slow functions are called while RTNL can be used
by other threads.

Protect the following members of netdev and napi by netdev_lock:
- defer_hard_irqs,
- gro_flush_timeout,
- irq_suspend_timeout.
The first two are written via sysfs (which this patch switches
to new lock), and netdev genl which holds both netdev and rtnl locks.
irq_suspend_timeout is only written by netdev genl.

Now that NAPI instances can't come and go without holding
netdev->lock we can trivially switch from rtnl_lock() to
netdev_lock() for setting netdev->threaded via sysfs.
Note that since we do not lock netdev_lock around sysfs
calls in the core we don't have to "trylock" like we do
with rtnl_lock.

Wrap napi_enable() / napi_disable() with netdev_lock().
Provide the "already locked" flavor of the API.
iavf needs the usual adjustment. A number of drivers call
napi_enable() under a spin lock, so they have to be modified
to take netdev_lock() first, then spin lock then call
napi_enable_locked().
Protecting napi_enable() implies that napi->napi_id is protected
by netdev_lock().

Hold netdev->lock when NAPIs are getting added or removed.
This will allow safe access to NAPI instances of a net_device
without rtnl_lock.

Some uAPI (netdev netlink) hide net_device's sub-objects while
the interface is down to ensure uniform behavior across drivers.
To remove the rtnl_lock dependency from those uAPIs we need a way
to safely tell if the device is down or up.
Add an indication of whether device is open or closed, protected
by netdev->lock. The semantics are the same as IFF_UP, but taking
netdev_lock around every write to ->flags would be a lot of code
churn.
We don't want to blanket the entire open / close path by netdev_lock,
because it will prevent us from applying it to specific structures -
core helpers won't be able to take that lock from any function
called by the drivers on open/close paths.
So the state of the flag is "pessimistic", as in it may report false
negatives, but never false positives.

Protect writes to netdev->reg_state with netdev_lock().
From now on holding netdev_lock() is sufficient to prevent
the net_device from getting unregistered, so code which
wants to hold just a single netdev around no longer needs
to hold rtnl_lock.
We do not protect the NETREG_UNREGISTERED -> NETREG_RELEASED
transition. We'd need to move mutex_destroy(netdev->lock)
to .release, but the real reason is that trying to stop
the unregistration process mid-way would be unsafe / crazy.
Taking references on such devices is not safe, either.
So the intended semantics are to lock REGISTERED devices.

The patch converts st,stm32-rcc.txt to the JSON schema, but it does more
than that. The old bindings, in fact, only covered the stm32f{4,7}
platforms and not the stm32h7. Therefore, to avoid patch submission tests
failing, it was necessary to add the corresponding compatible (i. e.
st,stm32h743-rcc) and specify that, in this case, 3 are the clocks instead
of the 2 required for the stm32f{4,7} platforms.
Additionally, the old bindings made no mention of the st,syscfg property,
which is used by both the stm32f{4,7} and the stm32h7 platforms.
The patch also fixes the files referencing to the old st,stm32-rcc.txt.

The hds-thresh option configures the threshold value of
the header-data-split.
If a received packet size is larger than this threshold value, a packet
will be split into header and payload.
The header indicates TCP and UDP header, but it depends on driver spec.
The bnxt_en driver supports HDS(Header-Data-Split) configuration at
FW level, affecting TCP and UDP too.
So, If hds-thresh is set, it affects UDP and TCP packets.
Example:
# ethtool -G <interface name> hds-thresh <value>
# ethtool -G enp14s0f0np0 tcp-data-split on hds-thresh 256
# ethtool -g enp14s0f0np0
Ring parameters for enp14s0f0np0:
Pre-set maximums:
...
HDS thresh: 1023
Current hardware settings:
...
TCP data split: on
HDS thresh: 256
The default/min/max values are not defined in the ethtool so the drivers
should define themself.
The 0 value means that all TCP/UDP packets' header and payload
will be split.

When tcp-data-split is UNKNOWN mode, drivers arbitrarily handle it.
For example, bnxt_en driver automatically enables if at least one of
LRO/GRO/JUMBO is enabled.
If tcp-data-split is UNKNOWN and LRO is enabled, a driver returns
ENABLES of tcp-data-split, not UNKNOWN.
So, `ethtool -g eth0` shows tcp-data-split is enabled.
The problem is in the setting situation.
In the ethnl_set_rings(), it first calls get_ringparam() to get the
current driver's config.
At that moment, if driver's tcp-data-split config is UNKNOWN, it returns
ENABLE if LRO/GRO/JUMBO is enabled.
Then, it sets values from the user and driver's current config to
kernel_ethtool_ringparam.
Last it calls .set_ringparam().
The driver, especially bnxt_en driver receives
ETHTOOL_TCP_DATA_SPLIT_ENABLED.
But it can't distinguish whether it is set by the user or just the
current config.
When user updates ring parameter, the new hds_config value is updated
and current hds_config value is stored to old_hdsconfig.
Driver's .set_ringparam() callback can distinguish a passed
tcp-data-split value is came from user explicitly.
If .set_ringparam() is failed, hds_config is rollbacked immediately.

great dependency wise. It does not allow the registering driver to be

LoongArch KVM changes for v6.14
1. Clear LLBCTL if secondary mmu mapping changed.
2. Add hypercall service support for usermode VMM.
This is a really small changeset, because the Chinese New Year
(Spring Festival) is coming. Happy New Year!

For stacking atomic writes, ensure that the start sector is aligned with
the device atomic write unit min and any boundary. Otherwise, we may
permit misaligned atomic writes.
Rework bdev_can_atomic_write() into a common helper to resuse the
alignment check. There also use atomic_write_hw_unit_min, which is more
proper (than atomic_write_unit_min).
Fixes: d7f36dc446e89 ("block: Support atomic writes limits for stacked devices")

The new option controls tests run on boot or module load. With the new
debugfs "run" dentry allowing to run tests on demand, an ability to disable
automatic tests run becomes a useful option in case of intrusive tests.
The option is set to true by default to preserve the existent behavior. It
can be overridden by either the corresponding module option or by the
corresponding config build option.

The hdev->reset is never used now and the hdev->cmd_timeout actually
does reset. This patch changes the call path from
hdev->cmd_timeout -> vendor_cmd_timeout -> btusb_reset -> hdev->reset
, to
hdev->reset -> vendor_reset -> btusb_reset
Which makes it clear when we export the hdev->reset to a wider usage
e.g. allowing reset from sysfs.
This patch doesn't introduce any behavior change.

Currently the platform filter cannot access any driver-specific state
which forces drivers installing a i8042 filter to have at least some
kind of global pointer for their filter.
Allow callers of i8042_install_filter() to submit a context pointer
which is then passed to the i8042 filter. This frees drivers from the
responsibility of having to manage this global pointer themself.
Also introduce a separate type for the i8042 filter (i8042_filter_t)
so that the function definitions can stay compact.
Tested on a Dell Inspiron 3505.

As of commit cb18cd26039f ("ASoC: soc-core: do rtd->id trick at
snd_soc_add_pcm_runtime()") the ID stored in the PCM runtime data can
no longer be safely used to index the priv->dai_props array. This is
because the ID may be modified during snd_soc_add_pcm_runtime(), thus
resulting in an ID that's no longer a valid array index.
To fix this, use the position of the dai_link stored inside the PCM
runtime data relative to the start of the dai_link array as index into
the priv->dai_props array.

The logic of GENERIC_PENDING_IRQ is backwards for historical reasons. Most
interrupt controllers allow to move the interrupt from arbitrary
contexts. If GENERIC_PENDING_IRQ is enabled by an architecture to support a
chip, which requires the affinity change to happen in interrupt context,
all other chips have to be marked with IRQF_MOVE_PCNTXT.
That's tedious and there is no real good reason for the extra flags in the
irq descriptor and the irq data status fields. In fact the decision whether
interrupts can be moved in arbitrary context or not is a property of the
interrupt chip.
To simplify adoption for RISC-V provide a new mechanism which is enabled
via a config switch and allows to add a flag to irq_chip::flags to request
that interrupt affinity changes are deferred. Setting the top level chip of
an interrupt evaluates the flag and maps it into the existing logic.
The config switch and the various PCNTXT flags are temporary until x86 is
converted over to this scheme. This intermediate step also allows trivial
backporting of the mechanism to plug the affinity change race of various
RISC-V interrupt controllers.
