I've got multiple reports of:
error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast].
Let's use the same trick than kernel/bpf/helpers.c to shut up that warning.
Even if we were on an architecture with addresses on more than 64 bits,
this isn't much of an issue as the address is not used as a pointer,
but as an hash and the caller is not supposed to go back to the kernel
address ever.
And while we change those, make sure we use u64 instead of __u64 for
consistency

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.

Add a function, ata_port_free(), that is used to free a ata_port,

freeing a ata_port in its own function, which will also free all the

spi: add devm_spi_optimize_message() helper
Helper from David Lechner <dlechner@baylibre.com>:

Add the necessary infrastructure to the IIO core to support a new
optional DMABUF based interface.
With this new interface, DMABUF objects (externally created) can be
attached to a IIO buffer, and subsequently used for data transfer.
A userspace application can then use this interface to share DMABUF
objects between several interfaces, allowing it to transfer data in a
zero-copy fashion, for instance between IIO and the USB stack.
The userspace application can also memory-map the DMABUF objects, and
access the sample data directly. The advantage of doing this vs. the
read() interface is that it avoids an extra copy of the data between the
kernel and userspace. This is particularly userful for high-speed
devices which produce several megabytes or even gigabytes of data per
second.
As part of the interface, 3 new IOCTLs have been added:
IIO_BUFFER_DMABUF_ATTACH_IOCTL(int fd):
Attach the DMABUF object identified by the given file descriptor to the
buffer.
IIO_BUFFER_DMABUF_DETACH_IOCTL(int fd):
Detach the DMABUF object identified by the given file descriptor from
the buffer. Note that closing the IIO buffer's file descriptor will
automatically detach all previously attached DMABUF objects.
IIO_BUFFER_DMABUF_ENQUEUE_IOCTL(struct iio_dmabuf *):
Request a data transfer to/from the given DMABUF object. Its file
descriptor, as well as the transfer size and flags are provided in the
"iio_dmabuf" structure.
These three IOCTLs have to be performed on the IIO buffer's file
descriptor, obtained using the IIO_BUFFER_GET_FD_IOCTL() ioctl.

To support virtual CPU hotplug, ACPI has added an 'online capable' bit
to the MADT GICC entries. This indicates a disabled CPU entry may not
be possible to online via PSCI until firmware has set enabled bit in
_STA.
This means that a "usable" GIC redistributor is one that is marked as
either enabled, or online capable. The meaning of the
acpi_gicc_is_usable() would become less clear than just checking the
pair of flags at call sites. As such, drop that helper function.
The test in gic_acpi_match_gicc() remains as testing just the
enabled bit so the count of enabled distributors is correct.
What about the redistributor in the GICC entry? ACPI doesn't want to say.
Assume the worst: When a redistributor is described in the GICC entry,
but the entry is marked as disabled at boot, assume the redistributor
is inaccessible.
The GICv3 driver doesn't support late online of redistributors, so this
means the corresponding CPU can't be brought online either.
Rather than modifying cpu masks that may already have been used,
register a new cpuhp callback to fail this case. This must run earlier
than the main gic_starting_cpu() so that this case can be rejected
before the section of cpuhp that runs on the CPU that is coming up as
that is not allowed to fail. This solution keeps the handling of this
broken firmware corner case local to the GIC driver. As precise ordering
of this callback doesn't need to be controlled as long as it is
in that initial prepare phase, use CPUHP_BP_PREPARE_DYN.
Systems that want CPU hotplug in a VM can ensure their redistributors
are always-on, and describe them that way with a GICR entry in the MADT.

Pull bcachefs fixes from Kent Overstreet:
"Simple stuff:
- NULL ptr/err ptr deref fixes
- fix for getting wedged on shutdown after journal error
- fix missing recalc_capacity() call, capacity now changes correctly
after a device goes read only
however: our capacity calculation still doesn't take into account
when we have mixed ro/rw devices and the ro devices have data on
them, that's going to be a more involved fix to separate accounting
for "capacity used on ro devices" and "capacity used on rw devices"
- boring syzbot stuff
Slightly more involved:
- discard, invalidate workers are now per device
this has the effect of simplifying how we take device refs in these
paths, and the device ref cleanup fixes a longstanding race between
the device removal path and the discard path
- fixes for how the debugfs code takes refs on btree_trans objects we
have debugfs code that prints in use btree_trans objects.
It uses closure_get() on trans->ref, which is mainly for the cycle
detector, but the debugfs code was using it on a closure that may
have hit 0, which is not allowed; for performance reasons we cannot
avoid having not-in-use transactions on the global list.
Introduce some new primitives to fix this and make the
synchronization here a whole lot saner"

Marvell 88PM886 is a PMIC which provides various functions such as
onkey, battery, charger and regulators. It is found for instance in the
samsung,coreprimevelte smartphone with which this was tested. Implement
basic support to allow for the use of regulators and onkey.

Some operations cannot be performed during the firmware flashing
process.
For example:
- Port must be down during the whole flashing process to avoid packet loss
while committing reset for example.
- Writing to EEPROM interrupts the flashing process, so operations like
ethtool dump, module reset, get and set power mode should be vetoed.
- Split port firmware flashing should be vetoed.
In order to veto those scenarios, add a flag in 'struct net_device' that
indicates when a firmware flash is taking place on the module and use it
to prevent interruptions during the process.

Ethtool can already retrieve information from a transceiver module
EEPROM by invoking the ethtool_ops::get_module_eeprom_by_page operation.
Add a corresponding operation that allows ethtool to write to a
transceiver module EEPROM.
The new write operation is purely an in-kernel API and is not exposed to
user space.
The purpose of this operation is not to enable arbitrary read / write
access, but to allow the kernel to write to specific addresses as part
of transceiver module firmware flashing. In the future, more
functionality can be implemented on top of these read / write
operations.
Adjust the comments of the 'ethtool_module_eeprom' structure as it is
no longer used only for read access.

Add a simple cleanup helper so we can cleanup struct path easily.
No need for any extra machinery. Avoid DEFINE_FREE() as it causes a
local copy of struct path to be used. Just rely on path_put() directly
called from a cleanup helper.
