Since the only crypto functions used by the mptcp code are the SHA-256
library functions and crypto_memneq(), select only the options needed
for those: CRYPTO_LIB_SHA256 and CRYPTO_LIB_UTILS.
Previously, CRYPTO was selected instead of CRYPTO_LIB_UTILS. That does
pull in CRYPTO_LIB_UTILS as well, but it's unnecessarily broad.
Years ago, the CRYPTO_LIB_* options were visible only when CRYPTO. That
may be another reason why CRYPTO is selected here. However, that was
fixed years ago, and the libraries can now be selected directly.

Otherwise the lock is susceptible to ever-changing false-sharing due to
unrelated changes. This in particular popped up here where an unrelated
change improved performance:
https://lore.kernel.org/oe-lkp/202511281306.51105b46-lkp@intel.com/
Stabilize it with an explicit annotation which also has a side effect
of furher improving scalability:
> in our oiginal report, 284922f4c5 has a 6.1% performance improvement comparing
> to parent 17d85f33a8.
> we applied your patch directly upon 284922f4c5. as below, now by
> "284922f4c5 + your patch"
> we observe a 12.8% performance improvements (still comparing to 17d85f33a8).
Note nothing was done for the other fields, so some fluctuation is still
possible.

In the DSP event handling code, a put_user() loop copies event data.
When the user buffer size is not aligned to 4 bytes, it could overwrite
beyond the buffer boundary.
Fix by adding a bounds check before put_user().

The global gpio_shared_lock has caused some issues when recursively
removing GPIO shared proxies. The thing is: we don't really need it.
Once created from an init-call, the shared GPIO data structures are
never removed, there's no need to protect the linked lists of entries
and references. All we need to protect is the shared GPIO descriptor
(which we already do with a per-entry mutex) and the auxiliary device
data in struct gpio_shared_ref.
Remove the global gpio_shared_lock and use a per-reference mutex to
protect shared references when adding/removing the auxiliary devices and
their GPIO lookup entries.

It's possible that not all proxy entries will be set up when the device

Inside print_data_reloc_error(), if extent_from_logical() failed we
return immediately.
However there are the following cases where extent_from_logical() can
return error but still holds a path:
- btrfs_search_slot() returned 0
- No backref item found in extent tree
- No flags_ret provided
This is not possible in this call site though.
So for the above two cases, we can return without releasing the path,
causing extent buffer leaks.

When trying to get the system name in the _HID path, after successfully
retrieving the subsystem ID the return value isn't set to 0 but instead
still kept at -ENODATA, leading to a false negative:

This reverts commit 252877a8701530fde861a4f27710c1e718e97caa.
Commit 252877a87015 ("btrfs: add ASSERTs on prealloc in qgroup
functions") tries to remove the kfree() on preallocated qgroup during
several call sites, but this cannot work as intended:
- btrfs_quota_enable()
- btrfs_create_qgroup()
If add_qgroup_item() failed, we go out_free_path() and at that time
prealloc is not yet utilized and will trigger the new ASSERT().
- btrfs_qgroup_inherit()
If qgroup_auto_inherit() failed, prealloc is not yet utilized and
will trigger the new ASSERT()

Initializing automatic __free variables to NULL without need (e.g.
branches with different allocations), followed by actual allocation is
in contrary to explicit coding rules guiding cleanup.h:
"Given that the "__free(...) = NULL" pattern for variables defined at
the top of the function poses this potential interdependency problem the
recommendation is to always define and assign variables in one statement
and not group variable definitions at the top of the function when
__free() is used."
Code does not have a bug, but is less readable and uses discouraged
coding practice, so fix that by moving declaration to the place of
assignment.

Pull f2fs updates from Jaegeuk Kim:
"This series focuses on minor clean-ups and performance optimizations
across sysfs, documentation, debugfs, tracepoints, slab allocation,
and GC. Furthermore, it resolves several corner-case bugs caught by
xfstests, as well as issues related to 16KB page support and
f2fs_enable_checkpoint.
Enhancement:
- wrap ASCII tables in literal blocks to fix LaTeX build
- optimize trace_f2fs_write_checkpoint with enums
- support to show curseg.next_blkoff in debugfs
- add a sysfs entry to show max open zones
- add fadvise tracepoint
- use global inline_xattr_slab instead of per-sb slab cache
- set default valid_thresh_ratio to 80 for zoned devices
- maintain one time GC mode is enabled during whole zoned GC cycle
Bug fix:
- ensure node page reads complete before f2fs_put_super() finishes
- do not account invalid blocks in get_left_section_blocks()
- revert summary entry count from 2048 to 512 in 16kb block support
- detect recoverable inode during dryrun of find_fsync_dnodes()
- fix age extent cache insertion skip on counter overflow
- add sanity checks before unlinking and loading inodes
- ensure minimum trim granularity accounts for all devices
- block cache/dio write during f2fs_enable_checkpoint()
- propagate error from f2fs_enable_checkpoint()
- invalidate dentry cache on failed whiteout creation
- avoid updating compression context during writeback
- avoid updating zero-sized extent in extent cache

If scsi_dh_attached_handler_name() fails to allocate the handler name,
dm-multipath (its only caller) assumes there is no attached device
handler, and sets the device up incorrectly. Return an error pointer
instead, so multipath can distinguish between failure, success where
there is no attached device handler, or when the path device is not a
SCSI device at all.

Commit 08b12cda6c44 ("scsi: ufs: core: Switch to scsi_get_internal_cmd()")
accidentally introduced a deadlock in the frequency scaling code.
ufshcd_clock_scaling_unprepare() may submit a device management command
while SCSI command processing is blocked. The deadlock was introduced by
using the SCSI core for submitting device management commands
(scsi_get_internal_cmd() + blk_execute_rq()). Fix this deadlock by calling
blk_mq_unquiesce_tagset() before any device management commands are
submitted by ufshcd_clock_scaling_unprepare().

The Device Tree binding schema for the SpacemiT P1 PMIC defines the main
input supply property as "vin-supply", but the driver defines the supply
name for BUCK and ALDO regulators as "vcc".
This causes the regulator core to lookup for a non-existent "vcc-supply".
Rename the supply from "vcc" to "vin", to match the DT binding and ensure
that the regulators input supplies are correctly resolved.
After this change, the regulators supply hierarchy is correctly reported:

"auto" was defined as a keyword back in the K&R days, but as a storage
type specifier. No one ever used it, since it was and is the default
storage type for local variables.
C++11 recycled the keyword to allow a type to be declared based on the
type of an initializer. This was finally adopted into standard C in
C23.
gcc and clang provide the "__auto_type" alias keyword as an extension
for pre-C23, however, there is no reason to pollute the bulk of the
source base with this temporary keyword; instead define "auto" as a
macro unless the compiler is running in C23+ mode.
This macro is added in <linux/compiler_types.h> because that header is
included in some of the tools headers, wheres <linux/compiler.h> is
not as it has a bunch of very kernel-specific things in it.

Similar in nature to ab107276607af90b13a5994997e19b7b9731e251. glibc-2.42
drops the legacy termio struct, but the ioctls.h header still defines some
TC* constants in terms of termio (via sizeof). Hardcode the values instead.
This fixes building Python for example, which falls over like:
./Modules/termios.c:1119:16: error: invalid application of 'sizeof' to incomplete type 'struct termio'

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize now
on the __ASSEMBLER__ macro that is provided by the compilers.
This is a completely mechanical patch (done with a simple "sed -i"
statement).

RTC_DRV_SPACEMIT_P1 is a subdevice of P1 and should depend on
MFD_SPACEMIT_P1 rather than selecting it directly. Using 'select'
does not always respect the parent's dependencies, so 'depends on'
is the safer and more correct choice.
Additionally, the default value depends on MFD_SPACEMIT_P1 rather
than ARCH_SPACEMIT.

Pull pin control updates from Linus Walleij:
"The technical details below. For me the CIX Semi and Axis
Communications ARTPEC-9 SoCs were the most interesting new drivers in
this merge window.
Core changes:
- Handle per-direction skew control in the generic pin config
- Drop the pointless subsystem boilerplate banner message during
boot. Less noise in the console. It's available as debug message if
someone really want it
New drivers:
- Samsung Exynos 8890 SoC support
- Samsung Exynos derived Axis Communications ARTPEC-9 SoC support.
These guys literally live next door to me, ARTPEC spells out "Axis
Real-Time Picture Encoding Chip" and is tailored for camera image
streams and is something they have evolved for a quarter of a
century
- Mediatek MT6878 SoC support
- Qualcomm Glymur PMIC support (mostly just compatible strings)
- Qualcomm Kaanapali SoC TLMM support
- Microchip pic64gx "gpio2" SoC support
- Microchip Polarfire "iomux0" SoC support
- CIX Semiconductors SKY1 SoC support
- Rockchip RK3506 SoC support
- Airhoa AN7583 chip support
Improvements:
- Improvements for ST Microelectronics STM32 handling of skew
settings so input and output can have different skew settings
- A whole bunch of device tree binding cleanups: Marvell Armada and
Berlin, Actions Semiconductor S700 and S900, Broadcom Northstar 2
(NS2), Bitmain BM1880 and Spreadtrum SC9860 are moved over to
schema"

Apple Silicon Macs (M1, etc.) have an RTC that is part of the PMU IC,
but most of the PMU functionality is abstracted out by the SMC.
On T600x machines, the RTC counter must be accessed via the SMC to
get full functionality, and it seems likely that future machines
will move towards making SMC handle all RTC functionality.
The SMC RTC counter access is implemented on all current machines
as of the time of this writing, on firmware 12.x. However, the RTC
offset (needed to set the time) is still only accessible via direct
PMU access. To handle this, we expose the RTC offset as an NVMEM
cell from the SPMI PMU device node, and this driver consumes that
cell and uses it to compute/set the current time.

Note, with the changes of v6 to v7 of the patch series adding the driver,
the content of this include file was moved into the driver file, and the
include file was dropped from that patch. It was simply missed to adjust
the section in MAINTAINERS that was newly added with that patch.
Drop the file entry to this non-existing file accordingly now.

The Renesas RZ/V2H RTC IP is based on the same RTCA3 IP as RZ/G3S
(r9a08g045), with the following differences:
- It lacks the time capture functionality
- The maximum supported periodic interrupt frequency is 128Hz instead
of 256Hz
- It requires two reset lines instead of one
Add new compatible string "renesas,r9a09g057-rtca3" for RZ/V2H and update
the binding accordingly:
- Allow "resets" to contain one or two entries depending on the SoC.
- Add "reset-names" property, but make it required only for RZ/V2H.
