Merge tag 'modules-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux
Pull module updates from Sami Tolvanen:
"Kernel symbol flags:
- Replace the separate *_gpl symbol sections (__ksymtab_gpl and
__kcrctab_gpl) with a unified symbol table and a new __kflagstab
section.
This section stores symbol flags, such as the GPL-only flag, as an
8-bit bitset for each exported symbol. This is a cleanup that
simplifies symbol lookup in the module loader by avoiding table
fragmentation and will allow a cleaner way to add more flags later
if needed.
Module signature UAPI:
- Move struct module_signature to the UAPI headers to allow reuse by
tools outside the kernel proper, such as kmod and
scripts/sign-file.
This also renames a few constants for clarity and drops unused
signature types as preparation for hash-based module integrity
checking work that's in progress.
Sysfs:
- Add a /sys/module/<module>/import_ns sysfs attribute to show the
symbol namespaces imported by loaded modules.
This makes it easier to verify driver API access at runtime on
systems that care about such things (e.g. Android).
Cleanups and fixes:
- Force sh_addr to 0 for all sections in module.lds. This prevents
non-zero section addresses when linking modules with 'ld.bfd -r',
which confused elfutils.
- Fix a memory leak of charp module parameters on module unload when
the kernel is configured with CONFIG_SYSFS=n.
- Override the -EEXIST error code returned by module_init() to
userspace. This prevents confusion with the errno reserved by the
module loader to indicate that a module is already loaded.
- Simplify the warning message and drop the stack dump on positive
returns from module_init().
- Drop unnecessary extern keywords from function declarations and
synchronize parse_args() arguments with their implementation"

Merge tag 'acpi-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI support updates from Rafael Wysocki:
"These include an update of the CMOS RTC driver and the related ACPI
and x86 code that, among other things, switches it over to using the
platform device interface for device binding on x86 instead of the PNP
device driver interface (which allows the code in question to be
simplified quite a bit), a major update of the ACPI Time and Alarm
Device (TAD) driver adding an RTC class device interface to it, and
updates of core ACPI drivers that remove some unnecessary and not
really useful code from them.
Apart from that, two drivers are converted to using the platform
driver interface for device binding instead of the ACPI driver one,
which is slated for removal, support for the Performance Limited
register is added to the ACPI CPPC library and there are some
janitorial updates of it and the related cpufreq CPPC driver, the ACPI
processor driver is fixed and cleaned up, and NVIDIA vendor CPER
record handler is added to the APEI GHES code.
Also, the interface for obtaining a CPU UID from ACPI is consolidated
across architectures and used for fixing a problem with the PCI TPH
Steering Tag on ARM64, there are two updates related to ACPICA, a
minor ACPI OS Services Layer (OSL) update, and a few assorted updates
related to ACPI tables parsing.
Specifics:
- Update maintainers information regarding ACPICA (Rafael Wysocki)
- Replace strncpy() with strscpy_pad() in acpi_ut_safe_strncpy()
(Kees Cook)
- Trigger an ordered system power off after encountering a fatal
error operator in AML (Armin Wolf)
- Enable ACPI FPDT parsing on LoongArch (Xi Ruoyao)
- Remove the temporary stop-gap acpi_pptt_cache_v1_full structure
from the ACPI PPTT parser (Ben Horgan)
- Add support for exposing ACPI FPDT subtables FBPT and S3PT (Nate
DeSimone)
- Address multiple assorted issues and clean up the code in the ACPI
processor idle driver (Huisong Li)
- Replace strlcat() in the ACPI processor idle drive with a better
alternative (Andy Shevchenko)
- Rearrange and clean up acpi_processor_errata_piix4() (Rafael
Wysocki)
- Move reference performance to capabilities and fix an uninitialized
variable in the ACPI CPPC library (Pengjie Zhang)
- Add support for the Performance Limited Register to the ACPI CPPC
library (Sumit Gupta)
- Add cppc_get_perf() API to read performance controls, extend
cppc_set_epp_perf() for FFH/SystemMemory, and make the ACPI CPPC
library warn on missing mandatory DESIRED_PERF register (Sumit
Gupta)
- Modify the cpufreq CPPC driver to update MIN_PERF/MAX_PERF in
target callbacks to allow it to control performance bounds via
standard scaling_min_freq and scaling_max_freq sysfs attributes and
add sysfs documentation for the Performance Limited Register to it
(Sumit Gupta)
- Add ACPI support to the platform device interface in the CMOS RTC
driver, make the ACPI core device enumeration code create a
platform device for the CMOS RTC, and drop CMOS RTC PNP device
support (Rafael Wysocki)
- Consolidate the x86-specific CMOS RTC handling with the ACPI TAD
driver and clean up the CMOS RTC ACPI address space handler (Rafael
Wysocki)
- Enable ACPI alarm in the CMOS RTC driver if advertised in ACPI FADT
and allow that driver to work without a dedicated IRQ if the ACPI
alarm is used (Rafael Wysocki)
- Clean up the ACPI TAD driver in various ways and add an RTC class
device interface, including both the RTC setting/reading and alarm
timer support, to it (Rafael Wysocki)
- Clean up the ACPI AC and ACPI PAD (processor aggregator device)
drivers (Rafael Wysocki)
- Rework checking for duplicate video bus devices and consolidate
pnp.bus_id workarounds handling in the ACPI video bus driver
(Rafael Wysocki)
- Update the ACPI core device drivers to stop setting
acpi_device_name() unnecessarily (Rafael Wysocki)
- Rearrange code using acpi_device_class() in the ACPI core device
drivers and update them to stop setting acpi_device_class()
unnecessarily (Rafael Wysocki)
- Define ACPI_AC_CLASS in one place (Rafael Wysocki)
- Convert the ni903x_wdt watchdog driver and the xen ACPI PAD driver
to bind to platform devices instead of ACPI devices (Rafael
Wysocki)
- Add devm_ghes_register_vendor_record_notifier(), use it in the PCI
hisi driver, and Add NVIDIA vendor CPER record handler (Kai-Heng
Feng)
- Consolidate the interface for obtaining a CPU UID from ACPI across
architectures and use it to address incorrect PCI TPH Steering Tag
on ARM64 resulting from the invalid assumption that the ACPI
Processor UID would always be the same as the corresponding logical
CPU ID in Linux (Chengwen Feng)"

nvme: Allow reauth from sysfs
Allow userspace to trigger a reauth (REPLACETLSPSK) from sysfs. This can be done by writing a zero to the sysfs file. echo 0 > /sys/devices/virtual/nvme-fabrics/ctl/nvme0/tls_configured_key In order to use the new keys for the admin queue we call controller reset. This isn't ideal, but I can't find a simpler way to reset the admin queue TLS connection.

module: expose imported namespaces via sysfs
Add /sys/module/*/import_ns to expose imported namespaces for currently loaded modules. The file contains one namespace per line and only exists for modules that import at least one namespace. Previously, the only way for userspace to inspect the symbol namespaces a module imports is to locate the .ko on disk and invoke modinfo(8) to decompress/parse the metadata. The kernel validated namespaces at load time, but it was otherwise discarded. Exposing this data via sysfs provides a runtime mechanism to verify which namespaces are being used by modules. For example, this allows userspace to audit driver API access in Android GKI, which uses symbol namespaces to restrict vendor drivers from using specific kernel interfaces (e.g., direct filesystem access).

zram: rename writeback_compressed device attr
Rename writeback_compressed attr to compressed_writeback to avoid possible
confusion and have more natural naming. writeback_compressed may look
like an alternative version of writeback while in fact
writeback_compressed only sets a writeback property. Make this
distinction more clear with a new compressed_writeback name.
This updates a feature which is new in 7.0-rcX.

platform/x86: uniwill-laptop: Rename FN lock and super key lock attrs
It turns out that both sysfs attributes actually directly control
the FN lock status/super key enable status, rather than the
triggering of the associated events. This behavior was first observed
on a Tuxedo notebook and was belived to be a hardware quirk.
However, it seems that i simply misunderstood the manual of the
OEM software for Intel NUC devices. The correct behavior is:
- fn_lock_toggle_enable enables/disables FN lock mode
- super_key_toggle_enable enables/disables the super key
Rename both sysfs attributes to avoid confusing users.

Pull f2fs updates from Jaegeuk Kim:
"In this development cycle, we focused on several key performance
optimizations:
- introducing large folio support to enhance read speeds for
immutable files
- reducing checkpoint=enable latency by flushing only committed dirty
pages
- implementing tracepoints to diagnose and resolve lock priority
inversion.
Additionally, we introduced the packed_ssa feature to optimize the SSA
footprint when utilizing large block sizes.
Detail summary:
Enhancements:
- support large folio for immutable non-compressed case
- support non-4KB block size without packed_ssa feature
- optimize f2fs_enable_checkpoint() to avoid long delay
- optimize f2fs_overwrite_io() for f2fs_iomap_begin
- optimize NAT block loading during checkpoint write
- add write latency stats for NAT and SIT blocks in
f2fs_write_checkpoint
- pin files do not require sbi->writepages lock for ordering
- avoid f2fs_map_blocks() for consecutive holes in readpages
- flush plug periodically during GC to maximize readahead effect
- add tracepoints to catch lock overheads
- add several sysfs entries to tune internal lock priorities
Fixes:
- fix lock priority inversion issue
- fix incomplete block usage in compact SSA summaries
- fix to show simulate_lock_timeout correctly
- fix to avoid mapping wrong physical block for swapfile
- fix IS_CHECKPOINTED flag inconsistency issue caused by

configfs-tsm-report: tdx_guest: Increase Quote buffer size to 128KB
Intel platforms are transitioning from traditional SGX-based attestation toward DICE-based attestation as part of a broader move toward open and standardized attestation models. DICE enables layered and extensible attestation, where evidence is accumulated across multiple boot stages. With SGX-based attestation, Quote sizes are typically under 8KB, as the payload consists primarily of Quote data and a small certificate bundle. Existing TDX guest code sizes the Quote buffer accordingly. DICE-based attestation produces significantly larger Quotes due to the inclusion of evidence (certificate chains) from multiple boot layers. The cumulative Quote size can reach approximately 100KB. Increase GET_QUOTE_BUF_SIZE to 128KB to ensure sufficient buffer capacity for DICE-based Quote payloads.

configfs-tsm-report: Document size limits for outblob attributes
The configfs-tsm-report interface can fail with -EFBIG when the attestation report generated by a TSM provider exceeds internal maximums (TSM_REPORT_OUTBLOB_MAX). However, this error condition and its handling are not currently documented in the ABI. Userspace tools need to understand how to interpret various error conditions when reading attestation reports. Document that reads fail with -EFBIG when reports exceed size limits, with guidance on how to resolve them.

Pull performance event updates from Ingo Molnar:
"x86 PMU driver updates:
- Add support for the core PMU for Intel Diamond Rapids (DMR) CPUs
(Dapeng Mi)
Compared to previous iterations of the Intel PMU code, there's been
a lot of changes, which center around three main areas:
- Introduce the OFF-MODULE RESPONSE (OMR) facility to replace the
Off-Core Response (OCR) facility
- New PEBS data source encoding layout
- Support the new "RDPMC user disable" feature
- Likewise, a large series adds uncore PMU support for Intel Diamond
Rapids (DMR) CPUs (Zide Chen)
This centers around these four main areas:
- DMR may have two Integrated I/O and Memory Hub (IMH) dies,
separate from the compute tile (CBB) dies. Each CBB and each IMH
die has its own discovery domain.
- Unlike prior CPUs that retrieve the global discovery table
portal exclusively via PCI or MSR, DMR uses PCI for IMH PMON
discovery and MSR for CBB PMON discovery.
- DMR introduces several new PMON types: SCA, HAMVF, D2D_ULA, UBR,
PCIE4, CRS, CPC, ITC, OTC, CMS, and PCIE6.
- IIO free-running counters in DMR are MMIO-based, unlike SPR.
- Also add support for Add missing PMON units for Intel Panther Lake,
and support Nova Lake (NVL), which largely maps to Panther Lake.
(Zide Chen)
- KVM integration: Add support for mediated vPMUs (by Kan Liang and
Sean Christopherson, with fixes and cleanups by Peter Zijlstra,
Sandipan Das and Mingwei Zhang)
- Add Intel cstate driver to support for Wildcat Lake (WCL) CPUs,
which are a low-power variant of Panther Lake (Zide Chen)
- Add core, cstate and MSR PMU support for the Airmont NP Intel CPU
(aka MaxLinear Lightning Mountain), which maps to the existing
Airmont code (Martin Schiller)
Performance enhancements:
- Speed up kexec shutdown by avoiding unnecessary cross CPU calls
(Jan H. Schönherr)
- Fix slow perf_event_task_exit() with LBR callstacks (Namhyung Kim)
User-space stack unwinding support:
- Various cleanups and refactorings in preparation to generalize the
unwinding code for other architectures (Jens Remus)
Uprobes updates:
- Transition from kmap_atomic to kmap_local_page (Keke Ming)
- Fix incorrect lockdep condition in filter_chain() (Breno Leitao)
- Fix XOL allocation failure for 32-bit tasks (Oleg Nesterov)
Misc fixes and cleanups:
- s390: Remove kvm_types.h from Kbuild (Randy Dunlap)
- x86/intel/uncore: Convert comma to semicolon (Chen Ni)
- x86/uncore: Clean up const mismatch (Greg Kroah-Hartman)
- x86/ibs: Fix typo in dc_l2tlb_miss comment (Xiang-Bin Shi)"

Pull erofs updates from Gao Xiang:
"In this cycle, inode page cache sharing among filesystems on the same
machine is now supported, which is particularly useful for
high-density hosts running tens of thousands of containers.
In addition, we fully isolate the EROFS core on-disk format from other
optional encoded layouts since the core on-disk part is designed to be
simple, effective, and secure. Users can use the core format to build
unique golden immutable images and import their filesystem trees
directly from raw block devices via DMA, page-mapped DAX devices,
and/or file-backed mounts without having to worry about unnecessary
intrinsic consistency issues found in other generic filesystems by
design. However, the full vision is still working in progress and will
spend more time to achieve final goals.
There are other improvements and bug fixes as usual, as listed below:
- Support inode page cache sharing among filesystems
- Formally separate optional encoded (aka compressed) inode layouts
(and the implementations) from the EROFS core on-disk aligned plain
format for future zero-trust security usage
- Improve performance by caching the fact that an inode does not have
a POSIX ACL
- Improve LZ4 decompression error reporting
- Enable LZMA by default and promote DEFLATE and Zstandard algorithms
out of EXPERIMENTAL status
- Switch to inode_set_cached_link() to cache symlink lengths
- random bugfixes and minor cleanups"

erofs: separate plain and compressed filesystems formally
The EROFS on-disk format uses a tiny, plain metadata design that prioritizes performance and minimizes complex inconsistencies against common writable disk filesystems (almost all serious metadata inconsistency cannot happen in well-designed immutable filesystems like EROFS). EROFS deliberately avoids artificial design flaws to eliminate serious security risks from untrusted remote sources by design, although human-made implementation bugs can still happen sometimes. Currently, there is no strict check to prevent compressed inodes, especially LZ4-compressed inodes, from being read in plain filesystems. Starting with erofs-utils 1.0 and Linux 5.3, LZ4_0PADDING sb feature is automatically enabled for LZ4-compressed EROFS images to support in-place decompression. Furthermore, since Linux 5.4 LTS is no longer supported, we no longer need to handle ancient LZ4-compressed EROFS images generated by erofs-utils prior to 1.0. To formally distinguish different filesystem types for improved security: - Use the presence of LZ4_0PADDING or a non-zero `dsb->u1.lz4_max_distance` as a marker for compressed filesystems containing LZ4-compressed inodes only; - For other algorithms, use `dsb->u1.available_compr_algs` bitmap. Note: LZ4_0PADDING has been supported since Linux 5.4 (the first formal kernel version), so exposing it via sysfs is no longer necessary and is now deprecated (but remain it for five more years until 2031): `dsb->u1` has been strictly non-zero for all EROFS images containing compressed inodes starting with erofs-utils v1.3 and it is actually a much better marker for compressed filesystems.

Merge tag 'iio-for-7.0a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next
Jonathan writes: IIO: New device support, features and cleanup for the 6.20/7.0 cycle. Slightly messier than normal unfortunately due to some conflicts and build config bugs related to I3C drivers. One last minute Kconfig fix right at the top after a linux-next report. I've simplified the Kconfig and made it match other instances in the kernel so that should be safe enough despite short soak time in front of build bots. Merge of an immutable branch from I3C to get some stubs that were missing and caused build issues with dual I2C / I3C drivers. This also brought in a drop of some deprecated interfaces so there is also one patch to update a new driver to not use those. We are having another go at using cleanup.h magic with the IIO mode claim functions after backing out last try at this. This time we have wrappers around the new ACQUIRE() and ACQUIRE_ERR() macros. Having been burnt once, we will be taking it a bit more slowly this time wrt to wide adoption of these! Thanks in particular to Kurt for taking on this core IIO work. New Device Support ================== adi,ad18113 - New driver to support the AD18113 amplifier - an interesting device due to the external bypass paths where we need to describe what gain those paths have in DT. Longer term it will be interesting to see if this simplistic description is enough for real deployments. adi,ad4062 - New driver for the AD4060 and AD4052 SAR ADCs including trigger, event and GPIO controller support. Follow up patch replaced use of some deprecated I3C interfaces prior to the I3C immutable branch merge as that includes dropping them. adi,ad4134 - New driver for the AD4134 24bit 4 channel simultaneous sampling ADC. adi,ad7768-1, - Add support for the ADAQ767-1, ADAQ7768-1 and ADAQ7769-1 ADCs after some rework to enable the driver to support multiple device types. adi,ad9467 - Add support for the similar ad9211 ADC to this existing driver. - Make the selection of 2s comp mode explicit for normal operation and switch to offset binary when entering calibration mode. honeywell,abp2 - New driver to support this huge family (100+) of board mount pressure and temperature sensors. maxim,max22007 - New drier for this 4 channel DAC. memsic,mmc5633 - New driver for this I2C/I3C magnetometer. Follow on patches fixed up issues related to single driver supporting both bus types. microchip,mcp747feb02 - New driver for the Microchip MCP47F(E/V)B(0/1/2)1, MCP47F(E/V)B(0/1/2)2, MCP47F(E/V)B(0/1/2)4 and MCP47F(E/V)B(0/1/2)8 buffered voltage output DACs. nxp,sar-adc - New driver support ADCs found on s32g2 and s32g3 platforms. ti,ads1018 - New drier for the ADS1018 and ADS1118 SPI ADCs. ti,ads131m02 - New driver supporting ADS131M(02/03/04/06/08)24-bit simultaneous sampling ADCs. Features ======== iio-core - New IIO_DEV_ACQUIRE_DIRECT_MODE() / IIO_DEV_ACQUIRE_FAILED() + equivalents for the much rarer case where the mode needs pinning whether or not it is in direct mode. These use the ACQUIRE() / ACQUIRE_ERR() infrastructure underneath to provide both simple checks on whether we got the requested mode and to provide scope based release. Applied in a few initial drivers. adi,ad9467 - Support calibbias control adi,adf4377 - Add support to act as a clock provider. adi,adxl380 - Support low power 1KHz sampling frequency mode. Required rework of how events and filters were configured, plus applying of constraints when in this mode. rf-digital,rfd77402 - Add interrupt support as alternative to polling for completion. st,lsm6dsx - Tap event detection (after considerable driver rework) Cleanup and Minor Fixes ======================= More minor cleanup such as typos, white space etc not called out except where they were applied to a lot of drivers. Various drivers. - Use of dev_err_probe() to cleanup error handling. - Introduce local struct device and struct device_node variables to reduce duplication of getting them from containing structs. - Ensure uses of iio_trigger_generic_data_rdy_poll() set IRQF_NO_THREAD as that function calls non threaded child interrupt handlers. - Replace IRQF_ONESHOT in not thread interrupt handlers with IRQF_NO_THREAD to ensure they run as intended. Drop one unnecessary case. iio-sw-device/trigger. - Constify configs_group_operations structures. iio-buffer-dma / buffer-dma-engine - Use lockdep_assert_held() to replace WARN_ON() to check lock is correctly held. - Make use of cleanup.h magic to simplify various code paths. - Make iio_dma_buffer_init() return void rather than always success. adi,ad7766 - Replace custom interrupt handler with iio_trigger_generic_data_rdy_poll() adi,ad9832 - Drop legacy platform_data support. adi,ade9000 - Add a maintainer entry. adi,adt7316 - Move to EXPORT_GPL_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() so the compiler can cleanly drop unused pm structures and callbacks. adi,adxl345 - Relax build constraint vs the driver that is in input so both may be built as modules and selection made at runtime. adi,adxl380 - Make sure we don't read tail entries in the hardware fifo if a partial new scan has been written. - Move to a single larger regmap_noinc_read() to read the hardware fifo. aspeed,ast2600 - Add missing interrupts property to DT binding. bosch,bmi270_i2c - Add missing MODULE_DEVICE_TABLE() macros so auto probing of modules can work. bosch,smi330 - Drop duplicate assignment of IIO_TYPE in smi330_read_avail() - Use new common field_get() and field_prep() helpers to replace local version. honeywell,mprls0025pa Fixes delayed to merge window as late in cycle and we didn't want to delay the rest of the series. - Allow Kconfig selection of specific bus sub-drivers rather than tying that to the buses themselves being supported. - Zero spi_transfer structure to avoid chance of unintentionally set fields effecting transfer. - Fix a potential timing violation wrt to the chip select to first clock edge timing. - As recent driver, take risk inherent in dropping interrupt direction from driver as that should be set by firmware. - Fix wrong reported number of data bits for channel. - Fix a pressure channel calculation bug. - Rework to allow embedding the tx buffer in the iio_priv() structure rather than requiring separate allocation. - Move the buffer clearing to the shared core bringing it into affect for SPI as well as I2C. - Stricter checks for status byte. - Greatly simplify the measurement sequence. - Add a copyright entry to reflect Petre's continued work on this driver. intersil,isl29018 - Switch from spritnf to sysfs_emit_at() to make it clear overflow can't occur. invensense,icm42600 - Allow sysfs access to temperature when buffered capture in use as it does not impact other sensor data paths. invensense,itg3200 - Check unused return value in read_raw() callback. men,z188 - Drop now duplicated module alias. rf-digital,rfd77402 - Add DT binding doc and explicit of_device_id table. - Poll for timeout with times as on datasheet, then replace opencoded version with read_poll_timeout(). sensiron,scd4x - Add missing timestamp channel.

f2fs: fix lock priority inversion issue
If userspace thread has held f2fs rw semaphore, due to its low priority, it could be runnable or preempted state for long time, during the time, it will block high priority thread which is trying to grab the same rw semaphore, e.g. cp_rwsem, io_rwsem... To fix such issue, let's detect thread's priority when it tries to grab f2fs_rwsem lock, if the priority is lower than a priority threshold, let's uplift the priority before it enters into critical region of lock, and restore the priority after it leaves from critical region. Meanwhile, introducing two new sysfs nodes: - /sys/fs/f2fs/<disk>/adjust_lock_priority, it is used to control whether the functionality is enable or not. ========== ================== Flag_Value Flag_Description ========== ================== 0x00000000 Disabled (default) 0x00000001 cp_rwsem 0x00000002 node_change 0x00000004 node_write 0x00000008 gc_lock 0x00000010 cp_global 0x00000020 io_rwsem ========== ================== - /sys/fs/f2fs/<disk>/lock_duration_priority, it is used to control priority threshold.

powerpc/pseries: move the PLPKS config inside its own sysfs directory
The /sys/firmware/secvar/config directory represents Power LPAR Platform KeyStore (PLPKS) configuration properties such as max_object_size, signed_ update_algorithms, supported_policies, total_size, used_space, and version. These attributes describe the PLPKS, and not the secure boot variables (secvars). Create /sys/firmware/plpks directory and move the PLPKS config inside this directory. For backwards compatibility, create a soft link from the secvar sysfs directory to this config and emit a warning stating that the older sysfs path has been deprecated. Separate out the plpks specific documentation from secvar.

iio: cros_ec: Allow enabling/disabling calibration mode
'calibrate' was a one-shot event sent to the sensor to calibrate itself. It is used on Bosch sensors (BMI160, BMA254). Light sensors work differently: They are first put in calibration mode, tests are run to collect information and calculate the calibration values to apply. Once done, the sensors are put back in normal mode. Accept boolean true and false (not just true) to enter/exit calibration state. Check "echo 0 > calibrate" is supported.

eeprom: at25: expose JEDEC ID via sysfs
Return the raw JEDEC ID bytes as returned by the RDID command, even for variations that have the bytes in reverse order. This way we can avoid ambiguity if the manufacturer ever releases a new chip that returns them according to standard.

speakup: Clarify bleep_time unit is milliseconds
The documentation had a TODO questioning whether the unit was in jiffies. The implementation in drivers/accessibility/speakup/main.c passes spk_bleep_time to msecs_to_jiffies(), confirming the unit is in milliseconds.
