const qualify the struct ctl_table argument in the proc_handler function
signatures. This is a prerequisite to moving the static ctl_table
structs into .rodata data which will ensure that proc_handler function
pointers cannot be modified.
This patch has been generated by the following coccinelle script:

* Code formatting was adjusted in xfs_sysctl.c to comply with code
conventions. The xfs_stats_clear_proc_handler,
xfs_panic_mask_proc_handler and xfs_deprecated_dointvec_minmax where
adjusted.
* The ctl_table argument in proc_watchdog_common was const qualified.
This is called from a proc_handler itself and is calling back into
another proc_handler, making it necessary to change it as part of the
proc_handler migration.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases
to get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions.
It's not all that useful for a "write a whole driver in rust" type
of thing, but the firmware bindings do help out the phy rust
drivers, and the driver core bindings give a solid base on which
others can start their work.
There is still a long way to go here before we have a multitude of
rust drivers being added, but it's a great first step.
- driver core const api changes.
This reached across all bus types, and there are some fix-ups for
some not-common bus types that linux-next and 0-day testing shook
out.
This work is being done to help make the rust bindings more safe,
as well as the C code, moving toward the end-goal of allowing us to
put driver structures into read-only memory. We aren't there yet,
but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems"

In commit d69d80484598 ("driver core: have match() callback in struct
bus_type take a const *"), the match callback for busses was changed to
take a const pointer to struct device_driver. Unfortunately I missed
fixing up the zorro code, and was only noticed after-the-fact by the
kernel test robot. Resolve this issue by properly changing the
zorro_bus_match() function.

The function driver_find_device() does not modify the struct
device_driver structure directly, so it is safe to be marked as a
constant pointer type. As that is fixed up, also change the function
signature on the inline functions that call this, which are:
driver_find_device_by_name()
driver_find_device_by_of_node()
driver_find_device_by_devt()
driver_find_next_device()
driver_find_device_by_acpi_dev()

In the match() callback, the struct device_driver * should not be
changed, so change the function callback to be a const *. This is one
step of many towards making the driver core safe to have struct
device_driver in read-only memory.
Because the match() callback is in all busses, all busses are modified
to handle this properly. This does entail switching some container_of()
calls to container_of_const() to properly handle the constant *.
For some busses, like PCI and USB and HV, the const * is cast away in
the match callback as those busses do want to modify those structures at
this point in time (they have a local lock in the driver structure.)
That will have to be changed in the future if they wish to have their
struct device * in read-only-memory.

Change device_driver_attach() and driver_attach() to take a const * to
struct device driver as neither of them modify the structure at all.
Also, for some odd reason, drivers/dma/idxd/compat.c had a duplicate
external reference to device_driver_attach(), so remove that to fix up
the build, it should never have had that there in the first place.

In the quest to make struct device constant, start by making
to_auxiliary_drv() return a constant pointer so that drivers that call
this can be fixed up before the driver core changes.
As the return type previously was not constant, also fix up all callers
that were assuming that the pointer was not going to be a constant one
in order to not break the build.

Uwe writes:
Change struct platform_driver::remove() to return void
This is step b) of the plan outlined in commit 5c5a7680e67b ("platform:
Provide a remove callback that returns no value"), which completes the
first major step of making the remove callback return no value. Up to
now it returned an int which however was mostly ignored by the driver
core and lured driver authors to believe there is some error handling.
Note that the Linux driver model assumes that removing a device cannot
fail, so this isn't about being lazy and not implementing error handling
in the core and so making .remove return void is the right thing to do.

struct platform_driver::remove returning an integer made driver authors
expect that returning an error code was proper error handling. However
the driver core ignores the error and continues to remove the device
because there is nothing the core could do anyhow and reentering the
remove callback again is only calling for trouble.
To prevent such wrong assumptions, change the return type of the remove
callback to void. This was prepared by introducing an alternative remove
callback returning void and converting all drivers to that. So .remove()
can be changed without further changes in drivers.
This corresponds to step b) of the plan outlined in commit
5c5a7680e67b ("platform: Provide a remove callback that returns no value").

Add support for the Exynos USB 3.1 DRD combo phy, as found in Exynos 9
SoCs like Google GS101. It supports USB SS, HS and DisplayPort.
In terms of UTMI+, this is very similar to the existing Exynos850
support in this driver. The difference is that this combo phy supports
both UTMI+ (HS) and PIPE3 (SS). It also supports DP alt mode.
The number of ports for UTMI+ and PIPE3 can be determined using the
LINKPORT register (which also exists on Exynos E850).
For SuperSpeed (SS) a new SS phy is in use and its PIPE3 interface is
new compared to Exynos E850, and also very different from the existing
support for older Exynos SoCs in this driver.
The SS phy needs a bit more configuration work and register tuning for
signal quality to work reliably, presumably due to the higher
frequency, e.g. to account for different board layouts. Additionally,
power needs to be enabled before writing to the SS phy registers.
This commit adds the necessary changes for USB HS and SS to work.
DisplayPort is out of scope in this commit.
Notes:
* For the register tuning, exynos5_usbdrd_apply_phy_tunes() has been
added with the appropriate data structures to support tuning at
various stages during initialisation. Since these are hardware
specific, the platform data is supposed to be populated accordingly.
The implementation is loosely modelled after the Samsung UFS PHY
driver.
There is one tuning state for UTMI+, PTS_UTMI_POSTINIT, to execute
after init and generally intended for HS signal tuning, as done in
this commit.
PTS_PIPE3_PREINIT PTS_PIPE3_INIT PTS_PIPE3_POSTINIT
PTS_PIPE3_POSTLOCK are tuning states for PIPE3. In the downstream
driver, preinit differs by Exynos SoC, and postinit and postlock
are different per board. The latter haven't been implemented for
gs101 here, because downstream doesn't use them on gs101 either.
* Signal lock acquisition for SS depends on the orientation of the
USB-C plug. Since there currently is no infrastructure to chain
connector events to both the USB DWC3 driver and this phy driver, a
work-around has been added in
exynos5_usbdrd_usbdp_g2_v4_pma_check_cdr_lock() to check both
registers if it failed in one of the orientations.
* Equally, we can only establish SS speed in one of the connector
orientations due to programming differences when selecting the lane
mux in exynos5_usbdrd_usbdp_g2_v4_pma_lane_mux_sel(), which really
needs to be dynamic, based on the orientation of the connector.
* As is, we can establish a HS link using any cable, and an SS link in
one orientation of the plug, falling back to HS if the orientation is
reversed to the expectation.

The ACE3 IP used in PantherLake exposes new bitfields in the ACTMCTL
register to better control clocks/delays. These bitfields were
reserved/zero in the ACE2.x IP, to simplify the integration the new
bifields are added unconditionally. The behavior will only be impacted
when the firmware exposes DSD properties to set non-zero values.

The notion of stream is by construction based on a multi-bus
capability, to allow for aggregation of Peripheral devices or
functions located on different segments. We currently count how many
master_rt contexts are used by a stream, but we don't have the dual
refcount of how many streams are allocated on a given bus. This
refcount will be useful to check if BTP/BRA streams can be allocated.
Note that the stream_refcount is modified in sdw_master_rt_alloc() and
sdw_master_rt_free() which are both called with the bus_lock mutex
held, so there's no need for refcount_ primitives for additional
protection.

Channel device name is used for sysfs, but also by dmatest filter function.
With dynamic channel registration, channels can be registered after dma
controller registration. Users may want to have specific channel names.
If name is NULL, the channel name relies on previous implementation,
dma<controller_device_id>chan<channel_device_id>.

Device drivers with optional firmware may still want to use the
asynchronous firmware loading interface. To avoid printing a
warning into the kernel log when the optional firmware is
absent, add a nowarn variant of this interface.

Pull random number generator updates from Jason Donenfeld:
"This adds getrandom() support to the vDSO.
First, it adds a new kind of mapping to mmap(2), MAP_DROPPABLE, which
lets the kernel zero out pages anytime under memory pressure, which
enables allocating memory that never gets swapped to disk but also
doesn't count as being mlocked.
Then, the vDSO implementation of getrandom() is introduced in a
generic manner and hooked into random.c.
Next, this is implemented on x86. (Also, though it's not ready for
this pull, somebody has begun an arm64 implementation already)
Finally, two vDSO selftests are added.
There are also two housekeeping cleanup commits"

The vDSO getrandom() implementation works with a buffer allocated with a
new system call that has certain requirements:
- It shouldn't be written to core dumps.
* Easy: VM_DONTDUMP.
- It should be zeroed on fork.
* Easy: VM_WIPEONFORK.
- It shouldn't be written to swap.
* Uh-oh: mlock is rlimited.
* Uh-oh: mlock isn't inherited by forks.
- It shouldn't reserve actual memory, but it also shouldn't crash when
page faulting in memory if none is available
* Uh-oh: VM_NORESERVE means segfaults.
It turns out that the vDSO getrandom() function has three really nice
characteristics that we can exploit to solve this problem:
1) Due to being wiped during fork(), the vDSO code is already robust to
having the contents of the pages it reads zeroed out midway through
the function's execution.
2) In the absolute worst case of whatever contingency we're coding for,
we have the option to fallback to the getrandom() syscall, and
everything is fine.
3) The buffers the function uses are only ever useful for a maximum of
60 seconds -- a sort of cache, rather than a long term allocation.
These characteristics mean that we can introduce VM_DROPPABLE, which
has the following semantics:
a) It never is written out to swap.
b) Under memory pressure, mm can just drop the pages (so that they're
zero when read back again).
c) It is inherited by fork.
d) It doesn't count against the mlock budget, since nothing is locked.
e) If there's not enough memory to service a page fault, it's not fatal,
and no signal is sent.
This way, allocations used by vDSO getrandom() can use:
VM_DROPPABLE | VM_DONTDUMP | VM_WIPEONFORK | VM_NORESERVE
And there will be no problem with OOMing, crashing on overcommitment,
using memory when not in use, not wiping on fork(), coredumps, or
writing out to swap.
In order to let vDSO getrandom() use this, expose these via mmap(2) as
MAP_DROPPABLE.
Note that this involves removing the MADV_FREE special case from
sort_folio(), which according to Yu Zhao is unnecessary and will simply
result in an extra call to shrink_folio_list() in the worst case. The
chunk removed reenables the swapbacked flag, which we don't want for
VM_DROPPABLE, and we can't conditionalize it here because there isn't a
vma reference available.
Finally, the provided self test ensures that this is working as desired.

Pull remoteproc updates from Bjorn Andersson:
- The maximum amount of DDR memory used by the Mediatek MT8188/MT8195
SCP is increased to handle new use cases. Handling of optional L1TCM
memory is made actually optional.
- An optimization is introduced to only clear the unused portion of IPI
shared buffers, rather than the entire buffer before writing the
message.
- Detection for IPC-only mode in the TI K3 DSP remoteproc driver is
corrected. The loglevel of a debug print in the same is lowered from
error.
- Support for attaching to an running remote processor is added to the
Xilinx R5F.
- An in-kernel implementation of the Qualcomm "protected domain mapper"
(aka service registry) service is introduced, to remove the
dependency on a userspace implementation to detect when the battery
monitor and USB Type-C port manager becomes available. This is then
integrated with the Qualcomm remoteproc driver.
- The Qualcomm PAS remoteproc driver gains support for attempting to
bust hwspinlocks held by the remote processor when it
crashed/stopped.
- The TI OMAP remoteproc driver is transitioned to use devres helpers
for various forms of allocations.
- Parsing of memory-regions in the i.MX remoteproc driver is improved
to avoid a NULL pointer dereference if the phandle reference is
empty. of_node reference counting is corrected in the same.

Add qcom_smem_bust_hwspin_lock_by_host to enable remoteproc to bust the
hwspin_lock owned by smem. In the event the remoteproc crashes
unexpectedly, the remoteproc driver can invoke this API to try and bust
the hwspin_lock and release the lock if still held by the remoteproc
device.

When a remoteproc crashes or goes down unexpectedly this can result in
a state where locks held by the remoteproc will remain locked possibly
resulting in deadlock. This new API hwspin_lock_bust() allows
hwspinlock implementers to define a bust operation for freeing previously
acquired hwspinlocks after verifying ownership of the acquired lock.

Pull module update from Luis Chamberlain:
"This is a super boring development cycle this time around for modules,
there is only one patch in this pull request.
The patch deals with a corner case set of dependencies which is not
resolved today to ensure users get the module they need on initramfs.
Currently only one module is known to exist which needs this, however
this can grow to capture other corner cases likely escaped and not
reported before. The kernel change is just a section update, the real
work is done and merged already on upstream kmod.
This has been on linux-next for 3 weeks now"

It has been seen that for some network mac drivers (i.e. lan78xx) the
related module for the phy is loaded dynamically depending on the current
hardware. In this case, the associated phy is read using mdio bus and then
the associated phy module is loaded during runtime (kernel function
phy_request_driver_module). However, no software dependency is defined, so
the user tools will no be able to get this dependency. For example, if
dracut is used and the hardware is present, lan78xx will be included but no
phy module will be added, and in the next restart the device will not work
from boot because no related phy will be found during initramfs stage.
In order to solve this, we could define a normal 'pre' software dependency
in lan78xx module with all the possible phy modules (there may be some),
but proceeding in that way, all the possible phy modules would be loaded
while only one is necessary.
The idea is to create a new type of dependency, that we are going to call
'weak' to be used only by the user tools that need to detect this situation.
In that way, for example, dracut could check the 'weak' dependency of the
modules involved in order to install these dependencies in initramfs too.
That is, for the commented lan78xx module, defining the 'weak' dependency
with the possible phy modules list, only the necessary phy would be loaded
on demand keeping the same behavior, but all the possible phy modules would
be available from initramfs.
The 'weak' dependency support has been included in kmod:
https://github.com/kmod-project/kmod/commit/05828b4a6e9327a63ef94df544a042b5e9ce4fe7
But, take into account that this can only be used if depmod is new enough.
If it isn't, depmod will have the same behavior as always (keeping backward
compatibility) and the information for the 'weak' dependency will not be
provided.

Pull more i2c updates from Wolfram Sang:
"The I2C core has two header documentation updates as the dependecies
are in now.
The I2C host drivers add some patches which nearly fell through the
cracks:
- Added descriptions in the DTS for the Qualcomm SM8650 and SM8550
Camera Control Interface (CCI).
- Added support for the "settle-time-us" property, which allows the
gpio-mux device to switch from one bus to another with a
configurable delay. The time can be set in the DTS. The latest
change also includes file sorting.
- Fixed slot numbering in the SMBus framework to prevent failures
when more than 8 slots are occupied. It now enforces a a maximum of
8 slots to be used. This ensures that the Intel PIIX4 device can
register the SPDs correctly without failure, even if other slots
are populated but not used"

Some hardware need some time to switch from a bus to another. This can
cause the first transfers following the selection of a bus to fail.
There is no way to configure this kind of waiting time in the driver.
Add support for the 'settle-time-us' device-tree property. When set,
the i2c_mux_gpio_select() applies a delay before returning, leaving
enough time to the hardware to switch to the new bus.

'struct power_supply_vbat_ri_table' are not modified in this driver.
Constifying these structures moves some data to a read-only section, so
increase overall security.
In order to do it, some code also needs to be adjusted to this new const
qualifier.

Either 5 different LED triggers are registered for battery power-supply
devices or a single online LED trigger is used for non battery power-supply
devices.
These 5 / 1 LED trigger(s) are never used at the same time. So there is
no need for a separate LED trigger pointer for the online trigger. Rename
the first battery trigger from charging_full_trig to just trig and use this
for the online trigger too.

Add power_supply_[un]register_led_trigger() helper functions.
The primary goal of this is as a preparation patch for adding an activate
callback to the power-supply LED triggers to ensure that power-supply
LEDs get the correct initial value when the LED gets registered after
the power_supply has been registered (this will use the psy back pointer).
There also is quite a lot of code duplication in the existing LED trigger
registration in the form of the kasprintf() for the name-template for each
trigger + related error handling. This duplication is removed by these
new helpers.

Pull MSI interrupt updates from Thomas Gleixner:
"Switch ARM/ARM64 over to the modern per device MSI domains.
This simplifies the handling of platform MSI and wire to MSI
controllers and removes about 500 lines of legacy code.
Aside of that it paves the way for ARM/ARM64 to utilize the dynamic
allocation of PCI/MSI interrupts and to support the upcoming non
standard IMS (Interrupt Message Store) mechanism on PCIe devices"

Most ARM(64) PCI/MSI domains mask and unmask in the parent domain after or
before the PCI mask/unmask operation takes place. So there are more than a
dozen of the same wrapper implementation all over the place.
Don't make the same mistake with the new per device PCI/MSI domains and
provide a new MSI feature flag, which lets the domain implementation
enable this sequence in the PCI/MSI code.
