The userspace can configure a loop using an ioctl call, wherein
a configuration of type loop_config is passed (see lo_ioctl()'s
case on line 1550 of drivers/block/loop.c). This proceeds to call
loop_configure() which in turn calls loop_set_status_from_info()
(see line 1050 of loop.c), passing &config->info which is of type
loop_info64*. This function then sets the appropriate values, like
the offset.
loop_device has lo_offset of type loff_t (see line 52 of loop.c),
which is typdef-chained to long long, whereas loop_info64 has
lo_offset of type __u64 (see line 56 of include/uapi/linux/loop.h).
The function directly copies offset from info to the device as
follows (See line 980 of loop.c):
lo->lo_offset = info->lo_offset;
This results in an overflow, which triggers a warning in iomap_iter()
due to a call to iomap_iter_done() which has:
WARN_ON_ONCE(iter->iomap.offset > iter->pos);
Thus, check for negative value during loop_set_status_from_info().

On link state change, the controller gets reset,
causing PPS to drop out and the PHC to lose its
time and calibration. So we restart it if needed,
restoring calibration and time registers.
Changes since v2:
* Add `fec_ptp_save_state()`/`fec_ptp_restore_state()`
* Use `ktime_get_real_ns()`
* Use `BIT()` macro
Changes since v1:
* More ECR #define's
* Stop PPS in `fec_ptp_stop()`

Commit 20f85ef89d94 ("drm/i915/backlight: use unique backlight device
names") added support for multiple backlight devices on dual panel
systems, but did so with error handling on -EEXIST from
backlight_device_register(). Unfortunately, that triggered a warning in
dmesg all the way down from sysfs_add_file_mode_ns() and
sysfs_warn_dup().
Instead of optimistically always attempting to register with the default
name ("intel_backlight", which we have to retain for backward
compatibility), check if a backlight device with the name exists first,
and, if so, use the card and connector based name.

If the GuC CTs are full and we need to stall the request submission
while waiting for space, we save the stalled request and where the stall
occurred; when the CTs have space again we pick up the request submission
from where we left off.
If a full GT reset occurs, the state of all contexts is cleared and all
non-guilty requests are unsubmitted, therefore we need to restart the
stalled request submission from scratch. To make sure that we do so,
clear the saved request after a reset.
Fixes note: the patch that introduced the bug is in 5.15, but no
officially supported platform had GuC submission enabled by default
in that kernel, so the backport to that particular version (and only
that one) can potentially be skipped.

Crucible + recent Mesa seems to sometimes hit:
GEM_BUG_ON(num_ccs_blks > NUM_CCS_BLKS_PER_XFER)
And it looks like we can also trigger this with gem_lmem_swapping, if we
modify the test to use slightly larger object sizes.
Looking closer it looks like we have the following issues in
migrate_copy():
- We are using plain integer in various places, which we can easily
overflow with a large object.
- We pass the entire object size (when the src is lmem) into
emit_pte() and then try to copy it, which doesn't work, since we
only have a few fixed sized windows in which to map the pages and
perform the copy. With an object > 8M we therefore aren't properly
copying the pages. And then with an object > 64M we trigger the
GEM_BUG_ON(num_ccs_blks > NUM_CCS_BLKS_PER_XFER).
So it looks like our copy handling for any object > 8M (which is our
CHUNK_SZ) is currently broken on DG2.

The while loop in raspberrypi_discover_clocks() relies on the assumption
that the id of the last clock element is zero. Because this data comes
from the Videocore firmware and it doesn't guarantuee such a behavior
this could lead to out-of-bounds access. So fix this by providing
a sentinel element.

on each function and cannot be re-assigned. Only the NQs are being
assigned to the VFs.

Address learning should initially be turned off by the driver for port
operation in standalone mode, then the DSA core handles changes to it
via ds->ops->port_bridge_flags().
Leaving address learning enabled while ports are standalone breaks any
kind of communication which involves port B receiving what port A has
sent. Notably it breaks the ksz9477 driver used with a (non offloaded,
ports act as if standalone) bonding interface in active-backup mode,
when the ports are connected together through external switches, for
redundancy purposes.
This fixes a major design flaw in the ksz9477 and ksz8795 drivers, which
unconditionally leave address learning enabled even while ports operate
as standalone.

Pull parisc fixes from Helge Deller:
"Some interesting background to the current patchset:
It turned out that the fldw instruction (which loads a 32-bit word
from memory into one half of a FP register) failed on unaligned
addresses and even trashed some other random FP register instead. It's
a trivial one-liner fix in the exception handler but this failure
dates back to the very beginnings of the parisc-port. It's strange
that it was never noticed before.
Another patch fixes an annoyance noticed by Randy Dunlap. Running
"make ARCH=parisc64 randconfig" always returned a 32-bit config,
although one would expect a 64-bit config. Masahiro Yamada suggested
to mimik sparc Kconfig code, which fixed the issue nicely. This
allowed to drop some compiler build checks too.
Third, it's possible to build an optimized 32-bit kernel for PA8X00
(64-bit) CPUs, which then wouldn't start on 32-bit-only (PA1.x)
machines. I've added a bootup check which prevents that and which
prints a message to the console. This can be tested with qemu, which
currently only supports 32-bit emulation.
The other patches are usual clean-up stuff like added return value
checks and typo fixes in comments.

There is no need to check if the cpufreq driver implements callback
cpufreq_driver::target_index. The logic in the __resolve_freq uses
the frequency table available in the policy. It doesn't matter if the
driver provides 'target_index' or 'target' callback. It just has to
populate the 'policy->freq_table'.
Thus, check only frequency table during the frequency resolving call.

Currently, when removing the SCMI PM driver not all the resources
registered with genpd subsystem are properly de-registered.
As a side effect of this after a driver unload/load cycle you get a
splat with a few warnings like this:
| debugfs: Directory 'BIG_CPU0' with parent 'pm_genpd' already present!
| debugfs: Directory 'BIG_CPU1' with parent 'pm_genpd' already present!
| debugfs: Directory 'LITTLE_CPU0' with parent 'pm_genpd' already present!
| debugfs: Directory 'LITTLE_CPU1' with parent 'pm_genpd' already present!
| debugfs: Directory 'LITTLE_CPU2' with parent 'pm_genpd' already present!

| debugfs: Directory 'DBGSYS' with parent 'pm_genpd' already present!
| debugfs: Directory 'GPUTOP' with parent 'pm_genpd' already present!
Add a proper scmi_pm_domain_remove callback to the driver in order to
take care of all the needed cleanups not handled by devres framework.

SCMI Reset protocol specification allows the asynchronous reset request
only when an autonomous reset action is specified. Reset requests based
on explicit assert/deassert of signals should not be served
asynchronously.
Current implementation will instead issue an asynchronous request in any
case, as long as the reset domain had advertised to support asynchronous
resets.
Avoid requesting the asynchronous resets when the reset action is not
of the autonomous type, even if the target reset domain does, in general,
support the asynchronous requests.

Accessing reset domains descriptors by the index upon the SCMI drivers
requests through the SCMI reset operations interface can potentially
lead to out-of-bound violations if the SCMI driver misbehave.
Add an internal consistency check before any such domains descriptors

There is a possible race condition (use-after-free) like below
(FREE) | (USE)
adf7242_remove | adf7242_channel
cancel_delayed_work_sync |
destroy_workqueue (1) | adf7242_cmd_rx
| mod_delayed_work (2)
|
The root cause for this race is that the upper layer (ieee802154) is
unaware of this detaching event and the function adf7242_channel can
be called without any checks.
To fix this, we can add a flag write at the beginning of adf7242_remove
and add flag check in adf7242_channel. Or we can just defer the
destructive operation like other commit 3e0588c291d6 ("hamradio: defer
ax25 kfree after unregister_netdev") which let the
ieee802154_unregister_hw() to handle the synchronization. This patch
takes the second option.

The recent commit 87d0e2f41b8c ("usb: typec: ucsi: add a common
function ucsi_unregister_connectors()") introduced a regression that
caused NULL dereference at reading the power supply sysfs. It's a
stale sysfs entry that should have been removed but remains with NULL
ops. The commit changed the error handling to skip the entries after
a NULL con->wq, and this leaves the power device unreleased.
For addressing the regression, the straight revert is applied here.
Further code improvements can be done from the scratch again.

Although commit 88f1669019bd ("scsi: sd: Rework asynchronous resume support")
eliminates a delay for some ATA disks after resume, it causes resume of ATA
disks to fail on other setups. See also:
* "Resume process hangs for 5-6 seconds starting sometime in 5.16"
(https://bugzilla.kernel.org/show_bug.cgi?id=215880).
* Geert's regression report
(https://lore.kernel.org/linux-scsi/alpine.DEB.2.22.394.2207191125130.1006766@ramsan.of.borg/).
This is what I understand about this issue:
* During resume, ata_port_pm_resume() starts the SCSI error handler. This
changes the SCSI host state into SHOST_RECOVERY and causes
scsi_queue_rq() to return BLK_STS_RESOURCE.
* sd_resume() calls sd_start_stop_device() for ATA devices. That function
in turn calls sd_submit_start() which tries to submit a START STOP UNIT
command. That command can only be submitted after the SCSI error handler
has changed the SCSI host state back to SHOST_RUNNING.
* The SCSI error handler runs on its own thread and calls
schedule_work(&(ap->scsi_rescan_task)). That causes
ata_scsi_dev_rescan() to be called from the context of a kernel
workqueue. That call hangs in blk_mq_get_tag(). I'm not sure why - maybe
because all available tags have been allocated by sd_submit_start()
calls (this is a guess).

This is caused by the global variable ad_ticks_per_sec being zero as
demonstrated by the reproducer script discussed below. This causes
all timer values in __ad_timer_to_ticks to be zero, resulting
in the periodic timer to never fire.
To reproduce:
Run the script in
`tools/testing/selftests/drivers/net/bonding/bond-break-lacpdu-tx.sh` which
puts bonding into a state where it never transmits LACPDUs.

call stack:

results:
Nothing is run in bond_3ad_initialize() because dev_addr equals
sys_mac_addr leaving the global ad_ticks_per_sec zero as it is
never initialized anywhere else.
The if check around the contents of bond_3ad_initialize() is no longer
needed due to commit 5ee14e6d336f ("bonding: 3ad: apply ad_actor settings

the bonding parameters whos set function calls
bond_3ad_update_ad_actor_settings(). This is because if
ad.system.sys_mac_addr is zero it will be set to the current bond mac
address, this causes the if check to never be true.

For some MAC drivers, they set the mac_managed_pm to true in its
->ndo_open() callback. So before the mac_managed_pm is set to true,
we still want to leverage the mdio_bus_phy_suspend()/resume() for
the phy device suspend and resume. In this case, the phy device is
in PHY_READY, and we shouldn't warn about this. It also seems that
the check of mac_managed_pm in WARN_ON is redundant since we already
check this in the entry of mdio_bus_phy_resume(), so drop it.

In ipa_smem_init(), a Qualcomm SMEM region is allocated (if needed)
and then its virtual address is fetched using qcom_smem_get(). The
physical address associated with that region is also fetched.
The physical address is adjusted so that it is page-aligned, and an
attempt is made to update the size of the region to compensate for
any non-zero adjustment.
But that adjustment isn't done properly. The physical address is
aligned twice, and as a result the size is never actually adjusted.
Fix this by *not* aligning the "addr" local variable, and instead
making the "phys" local variable be the adjusted "addr" value.

DSA has multiple ways of specifying a MAC connection to an internal PHY.
One requires a DT description like this:
port@0 {
reg = <0>;
phy-handle = <&internal_phy>;
phy-mode = "internal";
};
(which is IMO the recommended approach, as it is the clearest
description)
but it is also possible to leave the specification as just:
port@0 {
reg = <0>;
}
and if the driver implements ds->ops->phy_read and ds->ops->phy_write,
the DSA framework "knows" it should create a ds->slave_mii_bus, and it
should connect to a non-OF-based internal PHY on this MDIO bus, at an
MDIO address equal to the port address.
There is also an intermediary way of describing things:
port@0 {
reg = <0>;
phy-handle = <&internal_phy>;
};
In case 2, DSA calls phylink_connect_phy() and in case 3, it calls
phylink_of_phy_connect(). In both cases, phylink_create() has been
called with a phy_interface_t of PHY_INTERFACE_MODE_NA, and in both
cases, PHY_INTERFACE_MODE_NA is translated into phy->interface.
It is important to note that phy_device_create() initializes
dev->interface = PHY_INTERFACE_MODE_GMII, and so, when we use
phylink_create(PHY_INTERFACE_MODE_NA), no one will override this, and we
will end up with a PHY_INTERFACE_MODE_GMII interface inherited from the
PHY.
All this means that in order to maintain compatibility with device tree
blobs where the phy-mode property is missing, we need to allow the
"gmii" phy-mode and treat it as "internal".

In the original commit 9a34b45397e5 ("clk: Add support for runtime PM"),
the commit message mentioned that pm_runtime_put_sync() would be done
at the end of clk_core_unprepare(). This mirrors the operations in
clk_core_prepare() in the opposite order.
However, the actual code that was added wasn't in the order the commit
message described. Move clk_pm_runtime_put() to the end of
clk_core_unprepare() so that it is in the correct order.
