The power limit will be cached in smu->current_power_limit but
if the ASIC goes into S3 this value won't be restored.

The qcom_spi_program_oob() function uses only the last codeword to write
the OOB data into the flash, but it sets the CW_PER_PAGE field in the
CFG0 register as it would use all codewords.
It seems that this confuses the hardware somehow, and any access to the
flash fails with a timeout error after the function is called. The problem
can be easily reproduced with the following commands:
# dd if=/dev/zero bs=2176 count=1 > /tmp/test.bin
1+0 records in
1+0 records out
# flash_erase /dev/mtd4 0 0

Several months ago, Joshua Grisham submitted a patch [1]
for several ALC298 based sound cards.
The entry for the LG gram 16 in the alc269_fixup_tbl only matches the
Subsystem ID for the 16Z90R-Q and 16Z90R-K models [2]. My 16Z90R-A has a
different Subsystem ID [3]. I'm not sure why these IDs differ, but I
speculate it's due to the NVIDIA GPU included in the 16Z90R-A model that
isn't present in the other models.
I applied the patch to the latest Arch Linux kernel and the card was
initialized as expected.

When crossing into a new filesystem, the NFSv4 client will look up the
new directory, and then call nfs4_server_capabilities() as well as
nfs4_do_fsinfo() at least twice.

to retrieve just a minimal set of attributes.

The PF driver might be resumed just to configure VFs, but since
it is doing some asynchronous GuC reconfigurations after fresh
reset, we should wait until all pending works are completed.
This is especially important in case of LMEM provisioning, since
we also need to update the LMTT and send invalidation requests
to all GuCs, which are expected to be already in the VGT mode.

Doing devcoredump initializing before GT though look harmless, it leads
to problem during driver unbind. Because of this order, GT/Engine
release functions will be called before xe devcoredump release function
(xe_driver_devcoredump_fini) leading to the following kernel crash[1]
because the devcoredump functions might still use GT/Engine
datastructures after those are freed.
The following crash is observed while running the IGT
xe_wedged@wedged-at-any-timeout. The test forces a wedged state by
submitting a workload which hangs. Then does a unbind/rebind of the
driver to recover from the wedged state.
The hanged workload leads to a devcoredump. The following crash is
noticed when the devcoredump capture races with the driver unbind.
During driver unbind, the release function hw_engine_fini() will be
called which assigns NULL to hwe->gt. But the same data structure is
accessed during the coredump capture in the function
xe_engine_snapshot_print by reading snapshot->hwe->gt.
With this patch, we make sure the devcoredump is stopped before
deinitializing the core driver functions.

We already claim official support for SR-IOV PF/VF modes on PTL
and BMG platforms, but by default we start the Xe driver on those
platforms in non-virtualized mode (native) since we still have
max_vfs modparam set to disable creation of the VFs.
It's time to let the Xe driver support SR-IOV PF mode by default.
We were already testing this on our CI, which was relying on the
patch that was enabling it for CONFIG_DRM_XE_DEBUG used by our CI.

The size of struct bfq_iocq_bfqq_data can be reduced by moving a few
fields around.
On a x86_64, with allmodconfig, this shrinks the size from 144 to 128
bytes. The main benefit is to reduce the size of struct bfq_io_cq from
1360 to 1232.
This structure is stored in a dedicated slab cache. So reducing its size
improves cache usage.

- ability to mediate caps via the state machine instead of lut
- Add Ubuntu af_unix mediation, put it behind new v9 abi
Cleanups:
- fix typos and spelling errors
- cleanup kernel doc and code inconsistencies
- remove redundant checks/code
- remove unused variables
- Use str_yes_no() helper function
- mark tables static where appropriate
- make all generated string array headers const char *const
- refactor to doc semantics of file_perm checks
- replace macro calls to network/socket fns with explicit calls
- refactor/cleanup socket mediation code preparing for finer grained
mediation of different network families
- several updates to kernel doc comments
Bug fixes:

rules vector before any ruleset is assigned. If profile allocation
fails between ruleset allocation and assigning the first ruleset,
free_ruleset() will be called with a null pointer resulting in an
oops.

Merge an immutable branch between MFD, GPIO, Input and PWM to resolve
conflicts for the merge window pull request.

The driver called pwm_config() and pwm_enable() separately. Today both
are wrappers for pwm_apply_might_sleep() and it's more effective to call
this function directly and only once. Also don't configure the
duty_cycle and period if the next operation is to disable the PWM so
configure the PWM in max77693_haptic_enable().
With the direct use of pwm_apply_might_sleep() the need to call
pwm_apply_args() in .probe() is now gone, too, so drop this one.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull more tracing updates from Steven Rostedt:
- Remove unneeded goto out statements
Over time, the logic was restructured but left a "goto out" where the
out label simply did a "return ret;". Instead of jumping to this out
label, simply return immediately and remove the out label.
- Add guard(ring_buffer_nest)
Some calls to the tracing ring buffer can happen when the ring buffer
is already being written to at the same context (for example, a
trace_printk() in between a ring_buffer_lock_reserve() and a
ring_buffer_unlock_commit()).
In order to not trigger the recursion detection, these functions use
ring_buffer_nest_start() and ring_buffer_nest_end(). Create a guard()
for these functions so that their use cases can be simplified and not
need to use goto for the release.
- Clean up the tracing code with guard() and __free() logic
There were several locations that were prime candidates for using
guard() and __free() helpers. Switch them over to use them.
- Fix output of function argument traces for unsigned int values
The function tracer with "func-args" option set will record up to 6
argument registers and then use BTF to format them for human
consumption when the trace file is read. There are several arguments
that are "unsigned long" and even "unsigned int" that are either and
address or a mask. It is easier to understand if they were printed
using hexadecimal instead of decimal. The old method just printed all
non-pointer values as signed integers, which made it even worse for
unsigned integers.
For instance, instead of:
__local_bh_disable_ip(ip=-2127311112, cnt=256) <-handle_softirqs
show:
__local_bh_disable_ip(ip=0xffffffff8133cef8, cnt=0x100) <-handle_softirqs"

git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux
Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Enable a set of Clippy lints: 'ptr_as_ptr', 'ptr_cast_constness',
'as_ptr_cast_mut', 'as_underscore', 'cast_lossless' and
'ref_as_ptr'
These are intended to avoid type casts with the 'as' operator,
which are quite powerful, into restricted variants that are less
powerful and thus should help to avoid mistakes
- Remove the 'author' key now that most instances were moved to the
plural one in the previous cycle
'kernel' crate:
- New 'bug' module: add 'warn_on!' macro which reuses the existing
'BUG'/'WARN' infrastructure, i.e. it respects the usual sysctls and
kernel parameters:
warn_on!(value == 42);
To avoid duplicating the assembly code, the same strategy is
followed as for the static branch code in order to share the
assembly between both C and Rust
This required a few rearrangements on C arch headers -- the
existing C macros should still generate the same outputs, thus no
functional change expected there
- 'workqueue' module: add delayed work items, including a
'DelayedWork' struct, a 'impl_has_delayed_work!' macro and an
'enqueue_delayed' method, e.g.:
/// Enqueue the struct for execution on the system workqueue,
/// where its value will be printed 42 jiffies later.
fn print_later(value: Arc<MyStruct>) {
let _ = workqueue::system().enqueue_delayed(value, 42);
}
- New 'bits' module: add support for 'bit' and 'genmask' functions,
with runtime- and compile-time variants, e.g.:
static_assert!(0b00010000 == bit_u8(4));
static_assert!(0b00011110 == genmask_u8(1..=4));
assert!(checked_bit_u32(u32::BITS).is_none());
- 'uaccess' module: add 'UserSliceReader::strcpy_into_buf', which
reads NUL-terminated strings from userspace into a '&CStr'
Introduce 'UserPtr' newtype, similar in purpose to '__user' in C,
to minimize mistakes handling userspace pointers, including mixing
them up with integers and leaking them via the 'Debug' trait. Add
it to the prelude, too
- Start preparations for the replacement of our custom 'CStr' type
with the analogous type in the 'core' standard library. This will
take place across several cycles to make it easier. For this one,
it includes a new 'fmt' module, using upstream method names and
some other cleanups
Replace 'fmt!' with a re-export, which helps Clippy lint properly,
and clean up the found 'uninlined-format-args' instances
- 'dma' module:
- Clarify wording and be consistent in 'coherent' nomenclature
- Convert the 'read!()' and 'write!()' macros to return a 'Result'
- Add 'as_slice()', 'write()' methods in 'CoherentAllocation'
- Expose 'count()' and 'size()' in 'CoherentAllocation' and add
the corresponding type invariants
- Implement 'CoherentAllocation::dma_handle_with_offset()'
- 'time' module:
- Make 'Instant' generic over clock source. This allows the
compiler to assert that arithmetic expressions involving the
'Instant' use 'Instants' based on the same clock source
- Make 'HrTimer' generic over the timer mode. 'HrTimer' timers
take a 'Duration' or an 'Instant' when setting the expiry time,
depending on the timer mode. With this change, the compiler can
check the type matches the timer mode
- Add an abstraction for 'fsleep'. 'fsleep' is a flexible sleep
function that will select an appropriate sleep method depending
on the requested sleep time
- Avoid 64-bit divisions on 32-bit hardware when calculating
timestamps
- Seal the 'HrTimerMode' trait. This prevents users of the
'HrTimerMode' from implementing the trait on their own types
- Pass the correct timer mode ID to 'hrtimer_start_range_ns()'
- 'list' module: remove 'OFFSET' constants, allowing to remove
pointer arithmetic; now 'impl_list_item!' invokes
'impl_has_list_links!' or 'impl_has_list_links_self_ptr!'. Other
simplifications too
- 'types' module: remove 'ForeignOwnable::PointedTo' in favor of a
constant, which avoids exposing the type of the opaque pointer, and
require 'into_foreign' to return non-null
Remove the 'Either<L, R>' type as well. It is unused, and we want
to encourage the use of custom enums for concrete use cases
- 'sync' module: implement 'Borrow' and 'BorrowMut' for 'Arc' types
to allow them to be used in generic APIs
- 'alloc' module: implement 'Borrow' and 'BorrowMut' for 'Box<T, A>';
and 'Borrow', 'BorrowMut' and 'Default' for 'Vec<T, A>'
- 'Opaque' type: add 'cast_from' method to perform a restricted cast
that cannot change the inner type and use it in callers of
'container_of!'. Rename 'raw_get' to 'cast_into' to match it
- 'rbtree' module: add 'is_empty' method
- 'sync' module: new 'aref' submodule to hold 'AlwaysRefCounted' and
'ARef', which are moved from the too general 'types' module which
we want to reduce or eventually remove. Also fix a safety comment
in 'static_lock_class'
'pin-init' crate:
- Add 'impl<T, E> [Pin]Init<T, E> for Result<T, E>', so results are
now (pin-)initializers
- Add 'Zeroable::init_zeroed()' that delegates to 'init_zeroed()'
- New 'zeroed()', a safe version of 'mem::zeroed()' and also provide
it via 'Zeroable::zeroed()'
- Implement 'Zeroable' for 'Option<&T>', 'Option<&mut T>' and for
'Option<[unsafe] [extern "abi"] fn(...args...) -> ret>' for
'"Rust"' and '"C"' ABIs and up to 20 arguments
- Changed blanket impls of 'Init' and 'PinInit' from 'impl<T, E>
[Pin]Init<T, E> for T' to 'impl<T> [Pin]Init<T> for T'
- Renamed 'zeroed()' to 'init_zeroed()'
- Upstream dev news: improve CI more to deny warnings, use
'--all-targets'. Check the synchronization status of the two
'-next' branches in upstream and the kernel

If an error occurs in the loop that creates the device adapters, then a
reference to 'dev' still needs to be released.
Use for_each_child_of_node_scoped() to both fix the issue and save one line
of code.

This patch fixes an issue where the touchpad cursor movement becomes
slow on the Dell Precision 5560. Force the touchpad freq to 100khz
as a workaround.
Tested on Dell Precision 5560 with 6.14 to 6.14.6. Cursor movement
is now smooth and responsive.

When the first driver for Apple Silicon was upstreamed we accidentally
included `default ARCH_APPLE` in its Kconfig which then spread to almost
every subsequent driver. As soon as ARCH_APPLE is set to y this will
pull in many drivers as built-ins which is not what we want.
Thus, drop `default ARCH_APPLE` from Kconfig.

A security exploit was discovered in NFS over TLS in tls_alert_recv
due to its assumption that there is valid data in the msghdr's
iterator's kvec.
Instead, this patch proposes the rework how control messages are
setup and used by sock_recvmsg().
If no control message structure is setup, kTLS layer will read and
process TLS data record types. As soon as it encounters a TLS control
message, it would return an error. At that point, NFS can setup a kvec
backed control buffer and read in the control message such as a TLS
alert. Scott found that a msg iterator can advance the kvec pointer
as a part of the copy process thus we need to revert the iterator
before calling into the tls_alert_recv.

The usage of read_seqbegin_or_lock() in nfs_copy_boot_verifier()
is wrong. "seq" is always even and thus "or_lock" has no effect.
nfs_copy_boot_verifier() just copies 8 bytes and is supposed to be
very rare operation, so we do not need the adaptive locking in this case.

The gpio-mlxbf2 driver interfaces with four GPIO controllers,
device instances 0-3. There are two IRQ resources shared between
the four controllers, and they are found in the ACPI table for
instances 0 and 3. The driver should not use platform_get_irq(),
otherwise this error is logged when probing instances 1 and 2:

In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.
Switch to the regular pointer formatting which is safer and easier to
reason about.

In init_cpu_fullname(), a constant pointer to "model" property is
retrieved. It's later modified by the strsep() function, which is
illegal and corrupts kernel's FDT copy. This is shown by dmesg,
OF: fdt: not creating '/sys/firmware/fdt': CRC check failed
Create a mutable copy of the model property and do in-place operations
on the mutable copy instead. loongson_sysconf.cpuname lives across the
kernel lifetime, thus manually releasing isn't necessary.
Also move the of_node_put() call for the root node after the usage of
its property, since of_node_put() decreases the reference counter thus
usage after the call is unsafe.

The LoongArch mem= parameter parser was previously limited to the
mem=<size>@<start> format. This was inconvenient for the common use
case of simply capping the total system memory, as it forced users to
manually specify a start address. It was also inconsistent with the
behavior on other architectures.
This patch enhances the parser in early_parse_mem() to also support the
more user-friendly mem=<size> format. The implementation now checks for
the presence of the '@' symbol to determine the user's intent:
- If mem=<size> is provided (no '@'), the kernel now calls
memblock_enforce_memory_limit(). This trims memory from the top down
to the specified size.
- If mem=<size>@<start> is provided, the original behavior is retained
for backward compatibility. This allows for defining specific memory
banks.
This change introduces an important usage rule reflected in the code's
comments: the mem=<size> format should only be specified once on the
kernel command line. It acts as a single, global cap on total memory. In
contrast, the mem=<size>@<start> format can be specified multiple times
to define several distinct memory regions.

Now relocate_new_kernel_size is a .long value, which means 32bit, so its
high 32bit is undefined. This causes memcpy((void *)reboot_code_buffer,
relocate_new_kernel, relocate_new_kernel_size) in machine_kexec_prepare()
access out of range memories in some cases, and then end up with an ADE
exception.
So make relocate_new_kernel_size be a .quad value, which means 64bit, to
avoid such errors.
