75d5546f60 HID: hidraw: tighten ioctl command parsing
The handling for variable-length ioctl commands in hidraw_ioctl() is
rather complex and the check for the data direction is incomplete.

Simplify this code by factoring out the various ioctls grouped by dir
and size, and using a switch() statement with the size masked out, to
ensure the rest of the command is correctly matched.

be66a27b4f selftests/hid: update vmtest.sh for virtme-ng
This commit is a rewrite almost from scratch of vmtest.sh.

By relying on virtme-ng, we get rid of boot2container, reducing the
total bootup time (and network requirements). That means that we are
relying on the programs being installed on the host, but that shouldn't
be an issue. The generation of the kconfig is also now handled by
virtme-ng, so that's one less thing to worry.

I used tools/testing/selftests/vsock/vmtest.sh as a base and modified it
to look mostly like my previous script:
- removed the custom ssh handling
- make use of vng for compiling, which allows to bring remote
  compilation (and potentially remote compilation on a remote container)
- change the verbosity logic by having 2 levels:
  - first one shows the tests outputs
  - second level also shows the VM logs
- instead of only running the compiled kernel when it is built, if we
  are in the kernel tree, use the kernel artifacts there (and complain
  if they are not built)
- adapted the tests list to match the HID subsystem tests

e1c24d545b HID: playstation: Support DualSense audio jack event reporting
The DualSense controller complies with v1.0 of the USB Audio Class spec
(UAC1), hence it cannot advertise any jack detection capability.

However, this feature can be implemented in the generic USB audio driver
via quirks, i.e. by configuring an input handler to receive hotplug
events from the HID driver.

When operating in USB mode, register a dedicated input device for the
audio jack and use it to report all headphone and headset mic insert
events.

b1b4806c0c HID: playstation: Support DualSense audio jack hotplug detection
The default audio output path on DualSense controller hardware is set to
headphones, regardless of whether they are actually inserted or not.

Detect when the plugged state of the 3.5mm audio jack changes and toggle
audio output between headphones and internal speaker, as required.  The
latter is achieved by essentially routing the right channel of the audio
source to the mono speaker.

Additionally, adjust the speaker volume since its default level is too
low and, therefore, cannot generate any audible sound.

It's worth noting the audio functionality is currently not supported for
Bluetooth, hence it's limited to USB connectivity.

d7b744fa97 HID: playstation: Redefine DualSense input report status field
The 'status' member of struct dualsense_input_report is currently used
to store just the battery data, despite the fact that hardware is
capable to report two extra bytes of status information.

In preparation to make use of some of the additional data, redefine the
field type as a 3-byte array.

Moreover, to preserve consistency with the related DS_STATUS[0..2]_*
registers in datasheet, rename DS_STATUS_* bitfield macros accordingly.

dd86b69d20 fs/resctrl: Fix counter auto-assignment on mkdir with mbm_event enabled
rdt_resource::resctrl_mon::mbm_assign_on_mkdir determines if a counter will
automatically be assigned to an RMID, MBM event pair when its associated
monitor group is created via mkdir.

Testing shows that counters are always automatically assigned to new monitor
groups, whether mbm_assign_on_mkdir is set or not.

To support automatic counter assignment the check for mbm_assign_on_mkdir
should be in rdtgroup_assign_cntrs() that assigns counters during monitor
group creation. Instead, the check for mbm_assign_on_mkdir is in
rdtgroup_unassign_cntrs() that is called on monitor group deletion from where
counters should always be unassigned, whether mbm_assign_on_mkdir is set or
not.

Fix automatic counter assignment by moving the mbm_assign_on_mkdir check from
rdtgroup_unassign_cntrs() to rdtgroup_assign_cntrs().

cacheinfo_amd_init_llc_id() is only called on AMD systems that support
X86_FEATURE_TOPOEXT and amd_fill_cpuid4_info() uses the information from
CPUID leaf 0x8000001d on all these systems which is consistent with the
current open coded implementation.

70d1d98934 x86/cpu: Rename and move CPU model entry for Diamond Rapids
This model was added as INTEL_PANTHERCOVE_X (based on the name of the
core) with a comment that the platform name is Diamond Rapids. It was
also placed at the end of the file in a new section for family 19
processors.

This is different from previous naming as Andrew Cooper noted.
PeterZ agreed and posted a patch[1] to fix the name and move it in
sequence with other Xeon servers. But without a commit description or
sign-off the patch wasn't ever applied.

Patch updated to cover one additional use of the #define by turbostat
and to change the "Family 6" comment to also list 18 and 19 since new
models in these families are mixed in with family 6.

2ac207381c net/mlx5e: Prevent WQE metadata conflicts between timestamping and offloads
Update the WQE metadata assignment to avoid overriding existing
metadata when setting the sysport timestamp ID. Since timestamp IDs are
limited to 256 values, they use only the lower 8 bits of the metadata
field.

To avoid conflicts, move IPsec and MACsec metadata ID to bits 8 and 9,
and shift the MACsec fs_id accordingly. This ensures safe coexistence
of timestamping and offload features that use the same metadata field.

cce65f3244 net/mlx5: Refactor MACsec WQE metadata shifts
Introduce MLX5_ETH_WQE_FT_META_SHIFT as a shared base offset for
features that use the lower 8 bits of the WQE flow_table_metadata
field, currently used for timestamping, IPsec, and MACsec.

Define MLX5_ETH_WQE_FT_META_MACSEC_FS_ID_MASK so that fs_id occupies
bits 2–5, making it clear that fs_id occupies bits in the metadata.

Set MLX5_ETH_WQE_FT_META_MACSEC_MASK as the OR of the MACsec flag and
MLX5_ETH_WQE_FT_META_MACSEC_FS_ID_MASK, corresponding to the original
0x3E mask.

Update the fs_id macro to right-shift the MACsec flag by
MLX5_ETH_WQE_FT_META_SHIFT and update the RoCE modify-header action to
use it.

Introduce the helper macro MLX5_MACSEC_TX_METADATA(fs_id) to compose
the full shifted MACsec metadata value.

These changes make it explicit exactly which metadata bits carry MACsec
information, simplifying future feature exclusions when multiple
features share the WQE flowtable metadata.

In addition, drop the incorrect “RX flow steering” comment, since this
applies to TX flow steering.

06e5b72858 s390: Use generic TIF bits
No point in defining generic items and the upcoming RSEQ optimizations are
only available with this _and_ the generic entry infrastructure, which is
already used by s390. So no further action required here.

This leaves a comment about the AUDIT/TRACE/SECCOMP bits which are handled
by SYSCALL_WORK in the generic code, so they seem redundant, but that's a
problem for the s390 wizards to think about.

2958934348 asm-generic: Provide generic TIF infrastructure
Common TIF bits do not have to be defined by every architecture. They can
be defined in a generic header.

That allows adding generic TIF bits without chasing a gazillion of
architecture headers, which is again a unjustified burden on anyone who
works on generic infrastructure as it always needs a boat load of work to
keep existing architecture code working when adding new stuff.

While it is not as horrible as the ignorance of the generic entry
infrastructure, it is a welcome mechanism to make architecture people
rethink their approach of just leaching generic improvements into
architecture code and thereby making it accumulatingly harder to maintain
and improve generic code. It's about time that this changes.

Provide the infrastructure and split the TIF space in half, 16 generic and
16 architecture specific bits.

This could probably be extended by TIF_SINGLESTEP and BLOCKSTEP, but those
are only used in architecture specific code. So leave them alone for now.

Alloc
   - Add BorrowedPage type and AsPageIter trait
   - Implement Vmalloc::to_page() and VmallocPageIter
   - Implement AsPageIter for VBox and VVec
 
 DMA & Scatterlist
   - Add dma::DataDirection and type alias for dma_addr_t
   - Abstraction for struct scatterlist and struct sg_table
 
 DRM
   - In the DRM GEM module, simplify overall use of generics, add
     DriverFile type alias and drop Object::SIZE.
 
 Nova (Core)
   - Various register!() macro improvements (paving the way for lifting
     it to common driver infrastructure)
   - Minor VBios fixes and refactoring
   - Minor firmware request refactoring
   - Advance firmware boot stages; process Booter and patch its
     signature, process GSP and GSP bootloader
   - Switch development fimrware version to r570.144
   - Add basic firmware bindings for r570.144
   - Move GSP boot code to its own module
   - Clean up and take advantage of pin-init features to store most of
     the driver's private data within a single allocation

 Pin-Init
   - Merge pin-init PR from Benno
     - `#[pin_data]` now generates a `*Projection` struct similar to the
       `pin-project` crate.
 
     - Add initializer code blocks to `[try_][pin_]init!` macros: make
       initializer macros accept any number of `_: {/* arbitrary code
       */},` & make them run the code at that point.
 
     - Make the `[try_][pin_]init!` macros expose initialized fields via
       a `let` binding as `&mut T` or `Pin<&mut T>` for later fields.
 
 Rust
   - Various methods for AsBytes and FromBytes traits
 
 Tyr
   - Initial Rust driver skeleton for ARM Mali GPUs.
     - It can power up the GPU, query for GPU metatdata through MMIO and
       provide the metadata to userspace via DRM device IOCTL (struct
       drm_panthor_dev_query).
