5c63f3e78e arm64: dts: renesas: r9a07g0{43,44,54}: Remove TCIU8 interrupt from MTU3
The TCIU8 interrupt used to be documented in earlier revisions of the
user manuals, but has since been removed.  The corresponding entry is
now marked as reserved in the interrupt mapping tables of all supported
SoCs.

  - Page 486, Table 8.2 Interrupt mapping (7/13) in the Renesas RZ/G2UL
    Rev.1.40 User Manual
  - Page 363, Table 8.2 Interrupt Mapping (6/13) in the Renesas RZ/Five
    Rev.1.30 User Manual
  - Page 528, Table 8.2 Interrupt mapping (7/13) in the Renesas RZ/G2L
    and RZ/G2LC Rev.1.50 User Manual
  - Page 540, Table 8.2 Interrupt mapping (7/13) in the Renesas RZ/V2L
    Rev.1.50 User Manual

Remove the TCIU8 interrupt.  This does not cause any breakage as the
driver does not make use of the interrupts.

040eeafee0 firmware: tegra: bpmp: Add support for multi-socket platforms
On multi-socket platforms each socket has its own BPMP that is
registered with the kernel, so the existing single fixed "bpmp"
debugfs directory name cannot accommodate more than one instance.

Group the per-socket BPMP debugfs entries under a shared top-level
/sys/kernel/debug/bpmp/ directory, with each socket's BPMP device
under a "<numa-node-id>-bpmp" subdirectory:

  /sys/kernel/debug/bpmp/0-bpmp/...
  /sys/kernel/debug/bpmp/1-bpmp/...

For a multi-socket platform, the root debugfs bpmp/ directory is created
by the first BPMP device that is populated. For single-socket platforms,
the existing directory structure is preserved.

7ba53a3d1c firmware: tegra: bpmp: Propagate debugfs errors
The Tegra BPMP debugfs code returns -ENOMEM for most cases where calls
to debugfs_create_dir() or debugfs_create_file() fail. These debugfs
functions return an ERR_PTR with the actual error code on failure.
Therefore, update the Tegra BPMP debugfs code to propagate the actual
error code on failure.

2545b16e3e soc/tegra: pmc: Restrict power-off handler to Nexus 7
The Tegra PMC power-off handler exists solely to reboot the Nexus 7 into
a special bootloader mode when a USB cable is connected, so that the
bootloader can display battery status instead of powering off. There is
no reason to register it on any other Tegra board.

Guard the registration behind of_machine_is_compatible("asus,grouper")
and rename the handler to tegra_pmc_grouper_power_off_handler to make
its scope explicit. The of_machine_is_compatible() check inside the
handler itself is now redundant and is removed.

This also avoids occupying SYS_OFF_PRIO_FIRMWARE on boards that have
other handlers at that priority level.

4d61f03426 soc/tegra: pmc: Create PMC context dynamically
For legacy purposes, an early PMC context is needed to support certain
drivers and functionalities. However, when the PMC driver is probed in
the later boot stages, the early context is no longer needed. Allocate
the PMC context dynamically at probe time so that it can be used going
forward.

While at it, rename the early PMC context to more accurately reflect
what it is used for. It's technically not only for early boot stages,
but also to support some code that doesn't have a way of obtaining the
correct context otherwise (e.g. no access to device tree).

47ceab218c Input: Use named initializers for arrays of i2c_device_data
While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

07d5fb5379 i2c: core: fix adapter debugfs creation
Clients can be registered from bus notifier callbacks so the debugfs
directory needs to be created before registering the adapter as clients
use that directory as their debugfs parent.

Move debugfs creation before adapter registration to avoid having
clients create their debugfs directories in the debugfs root (which is
also more likely to fail due to name collisions).

Note that failure to allocate the adapter name must now be handled
explicitly as debugfs_create_dir() cannot handle a NULL name (unlike
device_add() which returns an error).

activation. If not, the firmware will use default power values.

Fix this by moving the iwl_mld_send_ap_tx_power_constraint_cmd()
call from iwl_mld_start_ap_ibss() to iwl_mld_assign_vif_chanctx(),
before iwl_mld_activate_link() for AP interfaces. Also update
the guard in the function to allow it to run before link activation
for AP interfaces.

ffb83b9835 Merge commit 'kvm-vmenter-load-store-regs' into HEAD
Convert the repeated register save/restore sequences into macros,
trading some level of implementation trickiness for conciseness (more
than one register can be saved/restored with one invocation) and a
smaller chance of cut and paste errors between VMX and SVM files.

This becomes more useful with the upcoming support for APX, which
would need to add 32 lines to the VM entry/exit paths.

46def663dd driver core: remove driver_set_override()
All buses have been converted from driver_set_override() to the generic
driver_override infrastructure introduced in commit cb3d1049f4
("driver core: generalize driver_override in struct device").

Buses now either opt into the generic sysfs callbacks via the
bus_type::driver_override flag, or use device_set_driver_override() /
__device_set_driver_override() directly.

Thus, remove the now-unused driver_set_override() helper.

171022c7d5 media: rc: igorplugusb: fix control request setup packet
Commit eac69475b0 ("media: rc: igorplugusb: heed coherency
rules") changed the control request storage from an embedded struct to
an allocated pointer so it can obey DMA coherency rules.

However, the driver still passes &ir->request to usb_fill_control_urb().
That points the URB setup packet at the pointer field itself rather than
at the allocated struct usb_ctrlrequest.

USB core then interprets pointer bytes as the setup packet. This can
produce an invalid bRequestType and trigger the control direction warning
reported by syzbot:

  usb 2-1: BOGUS control dir, pipe 80003580 doesn't match bRequestType 0

Pass ir->request itself as the setup packet.

Fix to point the error offset correctly for eprobe argument error.
In the cleanup commit 1b8b0cd754 ("tracing/probes: Move event parameter
fetching code to common parser"), due to incorrect backward compatibility
aimed at conforming to the test specifications, the error location was set
to 0 when a non-existent formal parameter was specified for Eprobe.
However, this should be corrected in both the test and the implementation
to point correct error position.

905b06d32a rust: x86: support Rust >= 1.98.0 target spec
Starting with Rust 1.98.0 (expected 2026-08-20), the target spec will not
support `x86-softfloat` anymore [1]. Instead, `softfloat` should be used,
which is an alias. Otherwise, one gets:

    error: error loading target specification: rustc-abi: invalid rustc abi: 'x86-softfloat'. allowed values: 'x86-sse2', 'softfloat' at line 3 column 32
      |
      = help: run `rustc --print target-list` for a list of built-in targets

Thus conditionally use one or the other depending on the version.

The alias has existed since Rust 1.95.0 (released 2026-04-16) [2], but
use the newer version instead to avoid changing how the build works for
existing compilers, at least until more testing takes place.
