- Set `compressedblks = 1` directly for non-bigpcluster cases. This
simplifies the logic a bit since lcluster sizes larger than one block
are unsupported and the details remain unclear.
- For Z_EROFS_LCLUSTER_TYPE_PLAIN pclusters, avoid assuming
`compressedblks = 1` by default. Instead, check if
Z_EROFS_ADVISE_BIG_PCLUSTER_2 is set.
It basically has no impact to existing valid images, but it's useful to
find the gap to prepare for large PLAIN pclusters.

efi_memattr_init() added a sanity check to avoid firmware caused corruption.
The check is based on efi memmap entry numbers, but kexec only takes the
runtime related memmap entries thus this caused many false warnings, see
below thread for details:
https://lore.kernel.org/all/20250108215957.3437660-2-usamaarif642@gmail.com/
Ard suggests to skip the efi memattr table in kexec, this makes sense because
those memattr fixups are not critical.

When using temperature measurement on Marvell 88Q2XXX devices and the
reset-gpios property is set in DT, the device does a hardware reset when
interface is brought down and up again. That means that the content of
the register MDIO_MMD_PCS_MV_TEMP_SENSOR2 is reset to default and that
leads to permanent deactivation of the temperature measurement, because
activation is done in mv88q2xxx_probe. To fix this move activation of
temperature measurement to mv88q222x_config_init.

struct platform_device::id was only set by board code, but since i.MX
became a devicetree-only platform, this will always be -1
(PLATFORM_DEVID_NONE).
Note: of_alias_get_id() returns a negative number on error and base
treats all negative errors the same, so we need not add any additional

When unload hclge driver, it tries to disable sriov first for each
ae_dev node from hnae3_ae_dev_list. If user unloads hns3 driver at
the time, because it removes all the ae_dev nodes, and it may cause
oops.
But we can't simply use hnae3_common_lock for this. Because in the
process flow of pci_disable_sriov(), it will trigger the remove flow
of VF, which will also take hnae3_common_lock.
To fixes it, introduce a new mutex to protect the unload process.

qcom,qcs615-ethqos
The qcs615-ride utilizes the same EMAC as the qcs404, rather than the
sm8150. The current incorrect fallback could result in packet loss.
The Ethernet on qcs615-ride is currently not utilized by anyone. Therefore,
there is no need to worry about any ABI impact.

channel
The NCSI state machine as it's currently implemented assumes that
transition to the next logical state is performed either explicitly by
calling `schedule_work(&ndp->work)` to re-queue itself or implicitly
after processing the predefined (ndp->pending_req_num) number of
replies. Thus to avoid the configuration FSM from advancing prematurely
and getting out of sync with the process it's essential to not skip
waiting for a reply.
This patch makes the code wait for reception of the Deselect Package
response for the last package probed before proceeding to channel
configuration.
Thanks go to Potin Lai and Cosmo Chou for the initial investigation and
testing.

Fix wrong GDM4 register definition, in Airoha SDK GDM4 is defined at
offset 0x2400 but this doesn't make sense as it does conflict with the
CDM4 that is in the same location.
Following the pattern where each GDM base is at the FWD_CFG, currently
GDM4 base offset is set to 0x2500. This is correct but REG_GDM4_FWD_CFG
and REG_GDM4_SRC_PORT_SET are still using the SDK reference with the
0x2400 offset. Fix these 2 define by subtracting 0x100 to each register
to reflect the real address location.

2. mount optiont NORECOVERY or DISABLE_ROLL_FORWARD is set, shown as commit
6781eabba1bd ("f2fs: give -EINVAL for norecovery and rw mount")
However, commit c426d99127b1 ("f2fs: Check write pointer consistency of open zones")

When a user TGT ticket expired, gssd returns EKEYEXPIRED to the RPC
layer for the upcall to create the security context. The RPC layer
then retries the upcall twice before returning the EKEYEXPIRED to
the NFS layer.
This results in three separate TCP connections to the NFS server being
created by gssd for each RPC request. These connections are not used
and left in TIME_WAIT state.
Note that for RPC call that uses machine credential, gssd automatically
renews the ticket. But for a regular user the ticket needs to be
renewed by the user before access to the krb5 share is allowed.
This patch removes the retries by RPC on EKEYEXPIRED so that these
unused TCP connections are not created.
Reproducer:

$ sleep 65
$ cd /mnt/krb5share
$ netstat -na |grep TIME_WAIT

The output format should provide a value that matches the one in
the /proc/<pid>/ns/net symlink. This makes it simpler to match the
rpc_xprt and rpc_clnt to a particular container.
Also, when the xprt defines the get_srcaddr operation, use that to
display the source address as well.

git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov:
- more conversions to the guard notation in the input core
- a fix for NXP BBNSM power key driver to clean up wake IRQ after
unbinding
- several new vendor/device ID pairs added to xpad game controller
driver
- several drivers switched to using str_enable_disable and similar
helpers instead of open-coding
- add mapping for F23 to atkbd driver so that MS "Copilot" key shortcut
works out of the box (if userspace is ready to handle it)
- evbug input handler has been removed (debugging through evdev is
strongly preferred to dumping all events into the kernel log).

raw_spin_locks can be traced by lockdep or tracing itself. Atomic64
operations can be used in the tracing infrastructure. When an architecture
does not have true atomic64 operations it can use the generic version that
disables interrupts and uses spin_locks.
The tracing ring buffer code uses atomic64 operations for the time
keeping. But because some architectures use the default operations, the
locking inside the atomic operations can cause an infinite recursion.
As atomic64 implementation is architecture specific, it should not be
using raw_spin_locks() but instead arch_spin_locks as that is the purpose
of arch_spin_locks. To be used in architecture specific implementations of
generic infrastructure like atomic64 operations.
Note, by switching from raw_spin_locks to arch_spin_locks, the locks taken
to emulate the atomic64 operations will not have lockdep, mmio, or any
kind of checks done on them. They will not even disable preemption,
although the code will disable interrupts preventing the tasks that hold
the locks from being preempted. As the locks held are done so for very
short periods of time, and the logic is only done to emulate atomic64, not
having them be instrumented should not be an issue.
