8e11a68e2e net/mlx5: Add adjphase function to support hardware-only offset control
The adjtime function supports using hardware to set the clock offset when
the delta was supported by the hardware. When the delta is not supported by
the hardware, the driver handles adjusting the clock. The newly-introduced
adjphase function is similar to the adjtime function, except it guarantees
that a provided clock offset will be used directly by the hardware to
adjust the PTP clock. When the range is not acceptable by the hardware, an
error is returned.

d0f332dc96 net/mlx5: Suppress error logging on UCTX creation
Suppress error logging that can be triggered by userspace upon DEVX UCTX
creation.

The reason that it's not suppressed today with the uid check to suppress
DEVX is that MLX5_CMD_OP_CREATE_UCTX command still doesn't have a uid as
it comes to create it..

62622dab0a ima: return IMA digest value only when IMA_COLLECTED flag is set
The IMA_COLLECTED flag indicates whether the IMA subsystem has
successfully collected a measurement for a given file object. Ensure
that we return the respective digest value stored within the iint
entry only when this flag has been set.

Failing to check for the presence of this flag exposes consumers of
this IMA API to receive potentially undesired IMA digest values when
an erroneous condition has been experienced in some of the lower level
IMA API code.

29814986b8 remoteproc: qcom_q6v5_pas: add support for dtb co-firmware loading
Starting from the SM8550 SoC, starting the aDSP, cDSP and MPSS will
require loading a separate "Devicetree" firmware.

In order to satisfy the load & authentication order required by the SM8550
SoC, the following is implemented:
- "Devicetree" firmware request & load in dedicated memory
- Q6V5 prepare
- Power Domain & Clocks enable
- "Devicetree" firmware authentication
- Main firmware load in dedicated memory
- Main firmware authentication
- Q6V5 startup
- "Devicetree" firmware metadata release
- Main metadata release

When booting older platforms, the "Devicetree" steps would be
bypassed and the load & authentication order would still be valid.

All currently known QMP UFS PHYs have the same offsets for register
sub-regions. Instead of using qmp_ufs_offsets_v5 for older generations
of PHYs, rename the offsets struct instance to remove _v5 suffix.

494de1dd83 phy: ti: j721e-wiz: Add support to enable LN23 Type-C swap
The WIZ acts as a wrapper for SerDes and has Lanes 0 and 2 reserved
for USB for type-C lane swap if Lane 1 and Lane 3 are linked to the
USB PHY that is integrated into the SerDes IP. The WIZ control register
has to be configured to support this lane swap feature.

The support for swapping lanes 2 and 3 is missing and therefore
add support to configure the control register to swap between
lanes 2 and 3 if PHY type is USB.

9a8a54b9a9 phy: ti: j721e-wiz: Manage TypeC lane swap if typec-dir-gpios not specified
It's possible that the Type-C plug orientation on the DIR line will be
implemented through hardware design. In that situation, there won't be
an external GPIO line available, but the driver still needs to address
this since the DT won't use the typec-dir-gpios property.

Add code to handle LN10 Type-C swap if typec-dir-gpios property is not
specified in DT.

fs: port vfs_*() helpers to struct mnt_idmap
Convert to struct mnt_idmap.

Last cycle we merged the necessary infrastructure in
256c8aed2b ("fs: introduce dedicated idmap type for mounts").
This is just the conversion to struct mnt_idmap.

Currently we still pass around the plain namespace that was attached to a
mount. This is in general pretty convenient but it makes it easy to
conflate namespaces that are relevant on the filesystem with namespaces
that are relevent on the mount level. Especially for non-vfs developers
without detailed knowledge in this area this can be a potential source for
bugs.

Once the conversion to struct mnt_idmap is done all helpers down to the
really low-level helpers will take a struct mnt_idmap argument instead of
two namespace arguments. This way it becomes impossible to conflate the two
eliminating the possibility of any bugs. All of the vfs and all filesystems
only operate on struct mnt_idmap.

They don't take the mount's idmapping into account.

Note, that after we converted everything over to struct mnt_idmap
mistakes such as the one here aren't possible anymore as struct
mnt_idmap cannot be passed to functions that operate on k{g,u}ids.
