0b205d0f0f wifi: iwlwifi: trans: remove hw_wfpm_id
We only need to have this during init in PCIe, so can
just re-read the value. Do that and don't store it.

a94d018996 wifi: iwlwifi: pass full FW info to transport
The code currently passes only the specific image that should
be loaded, but then has to pass the IML (image loader) out of
band, which is confusing. Pass the full FW data together with
desired image type, and use the IML from that.

This also cleans up the code in the various sub-drivers a bit
as they no longer have to look up and check for the image.

FW sends new notification version 2 indicating whether activating EMLSR

Simplify the logic here by tracking only suspended as a
status bit, and remove CMD_SEND_IN_D3 completely. There
is no value, since the op-mode sets the state and also

78cd408356 net: add missing instance lock to dev_set_promiscuity
Accidentally spotted while trying to understand what else needs
to be renamed to netif_ prefix. Most of the calls to dev_set_promiscuity
are adjacent to dev_set_allmulti or dev_disable_lro so it should
be safe to add the lock. Note that new netif_set_promiscuity is
currently unused, the locked paths call __dev_set_promiscuity directly.

35076d2223 erofs: ensure the extra temporary copy is valid for shortened bvecs
When compressed data deduplication is enabled, multiple logical extents
may reference the same compressed physical cluster.

The previous commit 94c43de735 ("erofs: fix wrong primary bvec
selection on deduplicated extents") already avoids using shortened
bvecs.  However, in such cases, the extra temporary buffers also
need to be preserved for later use in z_erofs_fill_other_copies() to
to prevent data corruption.

IOWs, extra temporary buffers have to be retained not only due to
varying start relative offsets (`pageofs_out`, as indicated by
`pcl->multibases`) but also because of shortened bvecs.

android.hardware.graphics.composer@2.1.so : 270696 bytes
   0:        0..  204185 |  204185 :  628019200.. 628084736 |   65536
-> 1:   204185..  225536 |   21351 :  544063488.. 544129024 |   65536
   2:   225536..  270696 |   45160 :          0..         0 |       0

com.android.vndk.v28.apex : 93814897 bytes
...
   364: 53869896..54095257 |  225361 :  543997952.. 544063488 |   65536
-> 365: 54095257..54309344 |  214087 :  544063488.. 544129024 |   65536
   366: 54309344..54514557 |  205213 :  544129024.. 544194560 |   65536
...

Both 204185 and 54095257 have the same start relative offset of 3481,
but the logical page 55 of `android.hardware.graphics.composer@2.1.so`
ranges from 225280 to 229632, forming a shortened bvec [225280, 225536)
that cannot be used for decompressing the range from 54095257 to
54309344 of `com.android.vndk.v28.apex`.

Since `pcl->multibases` is already meaningless, just mark `be->keepxcpy`
on demand for simplicity.

Again, this issue can only lead to data corruption if `-Ededupe` is on.

08e9f2d584 net: Lock netdevices during dev_shutdown
__qdisc_destroy() calls into various qdiscs .destroy() op, which in turn
can call .ndo_setup_tc(), which requires the netdev instance lock.

This commit extends the critical section in
unregister_netdevice_many_notify() to cover dev_shutdown() (and
dev_tcx_uninstall() as a side-effect) and acquires the netdev instance
lock in __dev_change_net_namespace() for the other dev_shutdown() call.

This should now guarantee that for all qdisc ops, the netdev instance
lock is held during .ndo_setup_tc().

0093cb194a ice: use DSN instead of PCI BDF for ice_adapter index
Use Device Serial Number instead of PCI bus/device/function for
the index of struct ice_adapter.

Functions on the same physical device should point to the very same
ice_adapter instance, but with two PFs, when at least one of them is
PCI-e passed-through to a VM, it is no longer the case - PFs will get
seemingly random PCI BDF values, and thus indices, what finally leds to
each of them being on their own instance of ice_adapter. That causes them
to don't attempt any synchronization of the PTP HW clock usage, or any
other future resources.

DSN works nicely in place of the index, as it is "immutable" in terms of
virtualization.

Fixes: 0e2bddf9e5 ("ice: add ice_adapter for shared data across PFs on the same NIC")

a7371be8c8 Merge branch 'devlink-sanitize-variable-typed-attributes'
Jiri Pirko says:

====================
devlink: sanitize variable typed attributes

This is continuation based on first two patches of
https://lore.kernel.org/20250425214808.507732-1-saeed@kernel.org

Better to take it as a separate patchset, as the rest of the original
patchset is probably settled.

This patchset is taking care of incorrect usage of internal NLA_* values
in uapi, introduces new enum (in patch #2) that shadows NLA_* values and
makes that part of UAPI.

The last two patches removes unnecessary translations with maintaining
clear devlink param driver api.

429ac62114 devlink: define enum for attr types of dynamic attributes
Devlink param and health reporter fmsg use attributes with dynamic type
which is determined according to a different type. Currently used values
are NLA_*. The problem is, they are not part of UAPI. They may change
which would cause a break.

To make this future safe, introduce a enum that shadows NLA_* values in
it and is part of UAPI.

Also, this allows to possibly carry types that are unrelated to NLA_*
values.

This happens because core::fmt::write() calls
core::fmt::rt::Argument::fmt(), which currently has CFI disabled:

library/core/src/fmt/rt.rs:
171     // FIXME: Transmuting formatter in new and indirectly branching to/calling
172     // it here is an explicit CFI violation.
173     #[allow(inline_no_sanitize)]

175     #[inline]
176     pub(super) unsafe fn fmt(&self, f: &mut Formatter<'_>) -> Result {

This causes a Control Protection exception, because FineIBT has sealed
off the original function's endbr64.

This makes rust currently incompatible with FineIBT. Add a Kconfig
dependency that prevents FineIBT from getting turned on by default
if rust is enabled.

[ Rust 1.88.0 (scheduled for 2025-06-26) should have this fixed [1],
  and thus we relaxed the condition with Rust >= 1.88.

  When `objtool` lands checking for this with e.g. [2], the plan is
  to ideally run that in upstream Rust's CI to prevent regressions
  early [3], since we do not control `core`'s source code.

  Alice tested the Rust PR backported to an older compiler.

  Peter would like that Rust provides a stable `core` which can be
  pulled into the kernel: "Relying on that much out of tree code is
  'unfortunate'".

Starting with Rust 1.88.0 (expected 2025-06-26) [1], `rustc` may move
back the `uninlined_format_args` to `style` from `pedantic` (it was
there waiting for rust-analyzer suppotr), and thus we will start to see
lints like:

    warning: variables can be used directly in the `format!` string
       --> rust/macros/kunit.rs:105:37
        |
    105 |         let kunit_wrapper_fn_name = format!("kunit_rust_wrapper_{}", test);
        |                                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    help: change this to
        |
    105 -         let kunit_wrapper_fn_name = format!("kunit_rust_wrapper_{}", test);
    105 +         let kunit_wrapper_fn_name = format!("kunit_rust_wrapper_{test}");

There is even a case that is a pure removal:

    warning: variables can be used directly in the `format!` string
      --> rust/macros/module.rs:51:13
       |
    51 |             format!("{field}={content}\0", field = field, content = content)

    51 +             format!("{field}={content}\0")

The lints all seem like nice cleanups, thus just apply them.

We may want to disable `allow-mixed-uninlined-format-args` in the future.

c016722fd5 rust: clean Rust 1.88.0's warning about clippy::disallowed_macros configuration
Starting with Rust 1.88.0 (expected 2025-06-26) [1], Clippy may start
warning about paths that do not resolve in the `disallowed_macros`
configuration:

    warning: `kernel::dbg` does not refer to an existing macro
      --> .clippy.toml:10:5
       |
    10 |     { path = "kernel::dbg", reason = "the `dbg!` macro is intended as a debugging tool" },
       |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This is a lint we requested at [2], due to the trouble debugging
the lint due to false negatives (e.g. [3]), which we use to emulate
`clippy::dbg_macro` [4]. See commit 8577c9dca7 ("rust: replace
`clippy::dbg_macro` with `disallowed_macros`") for more details.

Given the false negatives are not resolved yet, it is expected that
Clippy complains about not finding this macro.

Thus, until the false negatives are fixed (and, even then, probably we
will need to wait for the MSRV to raise enough), use the escape hatch
to allow an invalid path.

There are a lot of them (at least 300), but luckily they are all in
`bindgen`-generated code.

Thus clean all up by allowing it there.

Since unknown lints trigger a lint itself in older compilers, do it
conditionally so that we can keep the `unknown_lints` lint enabled.

a39f308709 rust: allow Rust 1.87.0's clippy::ptr_eq lint
Starting with Rust 1.87.0 (expected 2025-05-15) [1], Clippy may expand
the `ptr_eq` lint, e.g.:

    error: use `core::ptr::eq` when comparing raw pointers
       --> rust/kernel/list.rs:438:12
        |
    438 |         if self.first == item {
        |            ^^^^^^^^^^^^^^^^^^ help: try: `core::ptr::eq(self.first, item)`
        |
        = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#ptr_eq
        = note: `-D clippy::ptr-eq` implied by `-D warnings`
        = help: to override `-D warnings` add `#[allow(clippy::ptr_eq)]`

It is expected that a PR to relax the lint will be backported [2] by
the time Rust 1.87.0 releases, since the lint was considered too eager
(at least by default) [3].

Thus allow the lint temporarily just in case.

19f5ca461d objtool/rust: add one more noreturn Rust function for Rust 1.87.0
Starting with Rust 1.87.0 (expected 2025-05-15), `objtool` may report:

    rust/core.o: warning: objtool: _R..._4core9panicking9panic_fmt() falls
    through to next function _R..._4core9panicking18panic_nounwind_fmt()

    rust/core.o: warning: objtool: _R..._4core9panicking18panic_nounwind_fmt()
    falls through to next function _R..._4core9panicking5panic()

The reason is that `rust_begin_unwind` is now mangled:

    _R..._7___rustc17rust_begin_unwind

Thus add the mangled one to the list so that `objtool` knows it is
actually `noreturn`.

See commit 56d680dd23 ("objtool/rust: list `noreturn` Rust functions")
for more details.

Alternatively, we could remove the fixed one in `noreturn.h` and relax
this test to cover both, but it seems best to be strict as long as we can.

While at it, move of_node_put(child) inside the if block to avoid

73c46d9a93 clk: bcm: rpi: Add NULL check in raspberrypi_clk_register()
devm_kasprintf() returns NULL when memory allocation fails. Currently,
raspberrypi_clk_register() does not check for this case, which results
in a NULL pointer dereference.

Add NULL check after devm_kasprintf() to prevent this issue.
