43b16bf3e7 perf: Apply is_ignored_kernel_symbol() filter in ELF loading path for kernel DSOs
dso__load_sym_internal() had no filtering for .L* and L0* mapping
symbols while the kallsyms path already filters them via
is_ignored_kernel_symbol().

Add the same check gated by dso__kernel() so that kernel ELF objects
(vmlinux, .ko) have mapping symbols filtered across all architectures,
but userspace ELF objects are unaffected -- '$' is a valid prefix in
languages like Java and Scala.

The existing ARM/AArch64 and RISC-V architecture-specific mapping symbol
checks are preserved; the new is_ignored_kernel_symbol() check adds x86
local symbol (.L*, L0*) filtering and provides unified
cross-architecture coverage for kernel DSOs.

e987110f09 perf: Extract is_ignored_kernel_symbol() for kernel mapping symbol filtering
Mapping symbol filtering is scattered across multiple files with
inconsistent checks.  The kernel's own is_mapping_symbol() covers x86
local symbols ('.L*' and 'L0*') on top of the '$' prefix used by
ARM/AArch64/RISC-V, but the perf tool only checks '$'.

Extract is_ignored_kernel_symbol() into symbol.h matching the kernel
definition, and convert the kallsyms and ksymbol event paths to use it.
Add ksymbol event name validation and early mapping symbol filtering
before any state mutation.

c123ca6ee2 iio: light: opt3001: fix missing state reset on timeout
Currently in the function opt3001_get_processed(), there is a check
that directly returns -ETIMEDOUT if the conversion IRQ times out,
completely bypassing the err label, leaving ok_to_ignore_lock
permanently true, potentially breaking the device's falling threshold
interrupt detection.

Assign -ETIMEDOUT to the return variable and jump to the error label
to ensure ok_to_ignore_lock is properly reset.

789d22d778 powerpc tools perf: Initialize error code in auxtrace_record_init function
perf trace record fails some cases in powerpc

 # perf test "perf trace record and replay"
 128: perf trace record and replay                                    : FAILED!

  # perf trace record sleep 1
  # echo $?
    32

This is happening because of non-zero err value from
auxtrace_record__init() function.

 static int record__auxtrace_init(struct record *rec)
 {
        int err;

        if ((rec->opts.auxtrace_snapshot_opts || rec->opts.auxtrace_sample_opts)
            && record__threads_enabled(rec)) {
                pr_err("AUX area tracing options are not available in parallel streaming mode.\n");
                return -EINVAL;
        }

        if (!rec->itr) {
                rec->itr = auxtrace_record__init(rec->evlist, &err);
                if (err)
                        return err;
        }

Here "int err" is not initialised. The code expects "err" to be set from
auxtrace_record__init() function.

Update auxtrace_record__init() in arch/powerpc/util/auxtrace.c to clear
err value in the beginning.

- Clear err value in beginning of function. Any fail later will
set appropriate return code to err.

- Even if we haven't found any event for auxtrace, perf record
should continue for other events. NULL return
will indicate that there is no auxtrace record initialized.

- Not having "err" set here will affect monitoring of other events
also because perf record will fail seeing random value in err.

Set err to -EINVAL before invoking auxtrace_record__init() in
builtin-record.c

With the fix,

  # perf trace record sleep 1
  [ perf record: Woken up 2 times to write data ]
  [ perf record: Captured and wrote 0.033 MB perf.data (228 samples) ]

ef7607ab1c ALSA: seq: midi: Serialize output teardown with event_input
event_process_midi() borrows msynth->output_rfile.output and then
passes the substream to dump_midi() and snd_rawmidi_kernel_write()
without synchronizing with the output open/close transition.
midisynth_use() also publishes output_rfile before
snd_rawmidi_output_params() has finished.

The last midisynth_unuse() can therefore release the same rawmidi file
and free substream->runtime before snd_rawmidi_kernel_write1() takes
its runtime buffer reference. That leaves the event_input path using a
stale substream or runtime and can end in a NULL-deref or use-after-free.

Fix this with two pieces of synchronization. Keep a short IRQ-safe
spinlock only for publishing or clearing output_rfile and for pairing
the output snapshot with an snd_use_lock_t reference. Once
event_process_midi() has taken that in-flight reference, it drops the
spinlock before calling snd_seq_dump_var_event(), dump_midi(), or
snd_rawmidi_kernel_write(). midisynth_unuse() now detaches the visible
rawmidi file under the same spinlock, waits for the in-flight writers
to drain, and only then drains and releases the saved file.
midisynth_use() likewise opens into a local snd_rawmidi_file and
publishes it only after snd_rawmidi_output_params() succeeds.

The buggy scenario involves two paths, with each column showing the
order within that path:

event_input path:                     last unuse path:
1. event_process_midi() snapshots    1. midisynth_unuse() starts
   output_rfile.output.                 tearing down output_rfile.
2. dump_midi() reaches               2. snd_rawmidi_kernel_release()
   snd_rawmidi_kernel_write()           closes the output file.
   before runtime is pinned.         3. close_substream() frees
3. The callback keeps using             substream->runtime.
   the borrowed substream.

Include linux/bitfield.h for FIELD_GET().

Create new macros for bit manipulation in combination with manual bit
manipulation being replaced with FIELD_GET().

The current variable declaration and initializations are barely readable
and use comma separations across multiple lines. Refactor the
initializations so that mantissa and exp have separate declarations and
sign gets initialized later.

In addition (and due to the nature of the cleanup), fix a sign-extension
bug where, float32 would get bitwise anded with ~BIT(31)
(which is 0xFFFFFFFF7FFFFFFF) which corrupted the exponent.

1750ad1388 KVM: arm64: PMU: Preserve AArch32 counter low bits
AArch32 writes to PMU event counters cannot update the top 32 bits,
even when PMUv3p5 makes the counters 64-bit. KVM therefore needs to
preserve the existing high half and only update the low half written by
the guest, unless the caller explicitly forces a full reset through
PMCR.P.

The current code masks @val down to the old high half before taking
lower_32_bits(val), which means the low half is always zero. As a
result, AArch32 writes to event counters discard the guest-provided low
32 bits instead of storing them.

Build the new value from the old high 32 bits and the low 32 bits of
the value supplied by the guest.

or version discovery paths. Driver core treats that as a matched probe
failure and prints:

  |  arm-ffa arm-ffa: probe with driver arm-ffa failed with error -95

That is noisy for a firmware interface that can be absent on otherwise
valid systems. Driver core already treats -ENODEV and -ENXIO as quiet
rejected matches, so translate only the early unsupported discovery cases
to -ENODEV. Keep later setup failures unchanged so real FF-A
initialisation problems are still reported as probe failures.

ad1bcd3469 mtd: Consistently define pci_device_ids
Initializing a pci_device_id using plain list expressions is hard to
understand for a human who isn't into the Linux PCI subsystem. So for
each initializer use one of the PCI_DEVICE macros for .vendor, .device,
.subvendor and .subdevice and named initializers for the remaining
assignments. This makes it easier to parse and also more robust against
chagnes to the struct definition.

Also drop useless zeros and commas.

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

This change doesn't introduce changes to the compiled pci_device_id
array. Tested on x86 and arm64.

7fbdbc7d02 mtd: rawnand: qcom: embed nand_controller into qcom_nand_controller
The qcom_nand_controller had a struct nand_controller *controller
pointer that was assigned to (struct nand_controller *)&nandc[1],
with the allocation oversized by sizeof(*controller) to make room.
get_qcom_nand_controller() then walked backwards from chip->controller
using sizeof()-based arithmetic to recover the enclosing nandc.

Embed the nand_controller directly into qcom_nand_controller and use
container_of() in get_qcom_nand_controller(). The header now needs
the full rawnand.h definition rather than a forward declaration.

8ac45f4ff1 mtd: spinand: macronix: Enable randomizer support
Implement the 'set_randomizer' callback for Macronix SPI NAND chips.
The randomizer is enabled by setting bit 1 of the Configuration Register
(address 0x10).

This patch adds support for the following chips:
  - MX35LFxG24AD series
  - MX35UFxG24AD series

When the randomizer is enabled, data is scrambled internally during
program operations and automatically descrambled during read operations.
This helps reduce bit errors caused by program disturbance.

Please refer to the following link for randomizer feature:

cf496ebf13 dt-bindings: mtd: nand: Add nand-randomizer property
Add the 'nand-randomizer' property to control the data randomizer
feature. This is used to improve data reliability by reducing
cell-to-cell interference.

Depending on the hardware architecture, this property is designed to be
generic and can apply to either the NAND chip's internal randomizer
or the hardware randomizer engine embedded in the NAND host controller.

This property is defined as a uint32 enum (0 or 1) instead of a simple
boolean. This design choice explicitly supports the "not present" case.
If the property is omitted, the driver will not interfere and will leave
the randomizer in its current state (e.g., as already configured by the
bootloader or hardware default).

media pipelines on the device. This should be possible as long as the
media_pipelines don't use the same pads or pads that be configured while
the other media pipeline is streaming.

Move the media_pipeline to the imx_media_video_dev to be able to construct
media pipelines per imx capture device.

If different media pipelines in the media device conflict, the validation
will fail. Thus, the pipeline will fail to start and signal an error to
user space.

8368970b62 wifi: rtw89: usb: Support switching to USB 3 mode
The Realtek wifi 6/7 devices which support USB 3 are weird: when first
plugged in, they pretend to be USB 2. The driver needs to send some
commands to the device, which make it disappear and come back as a
USB 3 device.

Implement the required commands in rtw89.

Add a new function rtw89_usb_write32_quiet() to avoid the warnings
when writing to R_{AX,BE}_PAD_CTRL2. Even though the write succeeds,
usb_control_msg() returns -EPROTO, probably because the USB device
disappears immediately. This results in some confusing warnings in
the kernel log.

When a USB 3 device is plugged into a USB 2 port, rtw89 will try to
switch it to USB 3 mode only once. The device will disappear and come
back still in USB 2 mode, of course.

Tested with RTL8832AU, RTL8832BU, RTL8832CU, and RTL8912AU.

If a PHY status is present, the PHY status size should not be 0.

The frame size should not be less than or equal to 4 and should not

The rate should not exceed 4SS MCS9.
