8a32282175 block: fix comment for op_is_zone_mgmt() to include RESET_ALL
REQ_OP_ZONE_RESET_ALL is a zone management request, and op_is_zone_mgmt()
has returned true for it.

Update the comment to remove the misleading exception note so
the documentation matches the implementation.

552c1149af block: Clear BLK_ZONE_WPLUG_PLUGGED when aborting plugged BIOs
Commit fe0418eb9b ("block: Prevent potential deadlocks in zone write
plug error recovery") added a WARN check in disk_put_zone_wplug() to
verify that when the last reference to a zone write plug is dropped,
this zone write plug does not have the BLK_ZONE_WPLUG_PLUGGED flag set,
that is, that it is not plugged.

However, the function disk_zone_wplug_abort(), which is called for zone
reset and zone finish operations, does not clear this flag after
emptying a zone write plug BIO list. This can result in the
disk_put_zone_wplug() warning to trigger if the user (erroneously as
that is bad pratcice) issues zone reset or zone finish operations while
the target zone still has plugged BIOs.

Modify disk_put_zone_wplug() to clear the BLK_ZONE_WPLUG_PLUGGED flag.
And while at it, also add a lockdep annotation to ensure that this
function is called with the zone write plug spinlock held.

500920fa76 gpio updates for v6.19-rc1
GPIO core:
 - add proper support for shared GPIOs that's aiming to replace the
   current sharing mechanism (which provides no synchronization ot enable
   counting) and enable it for Qualcomm platforms
 - improve the software node GPIO lookup by using the fwnode
   representation instead of the software node's name which was prone to
   bugs (GPIO controllers don't have to use the software node's name as
   their kernel label)
 - remove the last user of legacy-of-mm-gpiochip.h and drop the header
 - move closer to removing the legacy gpio_request_one() routine
 - rename some symbols for consistency
 - shrink GPIO printk() helpers by reusing existing code
 - remove some redundant kernel messages
 - use min() instead of min_t() in GPIO ACPI code
 - use system_percpu_wq instead of system_wq in GPIO character device code
 
 New drivers:
 - add a driver for the QIXIS FPGA GPIO controller
 
 Driver improvements:
 - use modernized variants of power management macros across a wide array
   of drivers in order to avoid having to use the __maybe_unused attribute
 - convert gpio-elkhartlake and reset-gpio to using the auxiliary bus
   instead of the platform bus as they are not really described in
   firmware
 - use lock guards and update symbol prefixes in gpio-mmio
 - support the bryx radio interface kit in gpio-mpsse + refactor the
   driver
 - use software nodes for configuring the reset-gpio driver, including
   setting up the reference to the shared "reset" pin
 - check and propagate the return value of gpiod_set_value() to user-space
   in gpio-virtuser (this was previously not possible as this function
   returned void)
 - extend the gpio-regmap helper with more features (bypass cache for
   aliased inputs, force writes for aliased data registers, add a new
   configuration parameter)
 - remove unneeded includes from gpio-aspeed and gpio-latch
 - add support for Tegra410 to gpio-tegra186
 - replace PCI-specific PM with generic device-level PM in gpio-bt8xx
 - use dynamic GPIO range allocation in gpio-loongson-64bit
 - improve handling of level-triggered interrupts in gpio-pca953x
 - add suspend/resume support to gpio-fxl6408
 - add support for more models to gpio-menz127
 - optimize gpio-mvebu interrupt handling by avoiding unnecessary calls
   to mvebu_gpio_irq_handler()
 - make locking more consistent in gpio-grgpio
 
 Device-tree bindings:
 - document new NXP and Microchip models
 
 Documentation:
 - add a comprehensive compatibility and feature list for gpio-pca953x,
   which is a great addition as it's probably the most commonly used GPIO
   expander driver
 - kernel-doc tweaks
 
 Late fixes:
 - use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson

 "There's one new driver, lots of various updates to existing ones, some
  refactoring support for new models and misc tweaks and fixes.

  The biggest new feature in GPIO core is adding support for managed,
  enable-counted sharing of GPIO pins, something that - until now - was
  only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag
  which basically allowed drivers to "fight it out" for the descriptor
  and provided no synchronization. It was enabled on Qualcomm platforms
  (and thus is enabled on arm64 defconfig) and I plan on removing
  GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to
  the new mechanism.

205f1a0d18 firewire updates for v6.19
This release includes two changes for core functions, which affects all
 use cases of this subsystem.
 
  - Handle per-device interoperability quirks
    It is well known that some devices have quirks affecting
    interoperability. To identify such quirks at an early stages of
    device detection, the step for reading the configuration ROM contents
    has been changed. As a side effect, the entire detection process is
    now performed at the basic transaction speed (S100), without no trial
    to probe higher supported speeds.
    With this change, the following devices should now work with fewer
    issues:
    - TASCAM FW-1884, FW-1804, and FW-1082
    - MOTU Audio Express
 
  - Safer removals of host card
    There was a race condition between host card removal and handling of
    bus reset events in the workqueue. This appears to be a long standing
    issue (for a dozen years or so[1]), and recent changes to use more
    workqueues escalate it. To solve it, a new callback has been added to
    the 1394 OHCI PCI driver to unregister the interrupt sources and wait
    for workqueue completions when removing a card instance.

3df2470adc PM: runtime: Stop checking pm_runtime_barrier() return code
Apparently this test is the only code that checks the return code from
pm_runtime_barrier(), and it turns out that's for good reason -- it's
inherently racy, and a bad idea. We're going to make
pm_runtime_barrier() return void, so prepare for that by dropping any
return code checks.

This resolves some test failures seen like the following:

[   34.559694]     # pm_runtime_error_test: EXPECTATION FAILED at drivers/base/power/runtime-test.c:177
[   34.559694]     Expected 1 == pm_runtime_barrier(dev), but

fa5ef10561 spi: Updates for v6.19
This release is almost entirely new drivers, with a couple of small
 changes in generic code.  The biggest individual update is a rename of
 the existing Microchip driver and the addition of a new driver for the
 silicon SPI controller in their PolarFire SoCs.  The overlap between the
 soft IP supported by the current driver and this new one is regrettably
 all in the IP and not in the register interface offered to software.
 
  - Add a time offset parameter for offloads, allowing them to be defined
    in relation to each other.  This is useful for IIO type applcations
    where you trigger an operation then read the result after a delay.
  - Add a tracepoint for flash exec_ops, bringing the flash support more
    in line with the debuggability of vanilla SPI.
  - Support for Airoha EN7523, Arduino MCUs, Aspeed AST2700, Microchip
    PolarFire SPI controllers, NXP i.MX51 ECSPI target mode, Qualcomm
    IPQ5414 and IPQ5332, Renesas RZ/T2H, RZ/V2N and RZ/2NH and SpacemiT K1
    QuadSPI.
 
 There's also a small set of ASoC cleanups that I mistakenly applied to
 the SPI tree and then put more stuff on top of before it was brought to
 my attention, sorry about that.

0a9431fa74 regulator: Updates for v6.19
This is a relatively busy release for the regulator API, as well as a
 good collection of new drivers we've got a little bit of core work and a
 bunch of cleanup throughout the subsystem:
 
  - Support for propagating undervoltage events to child regulators.
  - Undo enables done on supplies when setting enabling regulators via
    constraints fails.
  - Pull in some gpiolib changes adding support for shared GPIOs to
    the gpiolib core, using them to replace the open coded variant of this
    that we've had in the regulator API for a long time.
  - Support for Fitipower FP9931 and JD9330, Mediatek MT6316, MT6363 and
    MT6373, NXP PF1550 and Qualcomm PMH01XX and PMCX0102
 
 The PF1550 support was originally going to go via the MFD tree but
 Krzysztof's cleanup work overlapped with it so I pulled in Lee's signed
 tag with support for the device.

edd2b9832d Core MTD changes:
- We must ignore error -ENOENT from parsers on subpartitions which is a
   legitimate return value.
 
 - PM support is added to the intel-dg driver.
 
 Raw NAND changes:
 
 - The major change in this MR will be the support for the Allwinner H616
   NAND controller, which lead to numerous changes and cleanups in the
   driver.
 
 - Another notable change on this driver is the use of
   field_get()/field_prep(), but since the global support for this
   helpers is going to be merged in the same release as we start using
   these helpers, it implies undefining them in the first place to avoid
   warnings. Depending on the merging order (Yuri's bitmap branch or
   mtd/next), a temporary warning may arise.
 
 - Marvell drivers layout handling changes have also landed, they fix
   previous definitions and abuses that have been made previously, which
   implied to relax the ECC parameters validation in the core a bit.
 
 - The Cadence NAND controller driver gets NV-DDR interface support.
 
 SPI NAND changes:
 
 - Support for FudanMicro FM25S01BI3 and ESMT F50L1G41LC is added.
 
 SPI NOR changes:
 
 - Fix SMPT parsing for S25FS-S flash family. They report variable dummy
   cycles for reads. This results in the default of 0 being used. This
   works for other Infineon chips, but not for the S25FS-S family. They
   need 8 dummy cycles. Add fixup hooks to specify that. Also add fixup
   hooks to fix incorrect map ID data in SFDP.
 
 - Add support for a bunch of Winbond flashes. Their block protection
   information is not discoverable, so they need to have an entry in the
   flash tables to describe that.
 
 - Some cleanups for Micron flash support.
 
 - Add support for Micron mt35xu01gbba.
 
 - Some SPI controllers like the Intel one on the PCI bus do not support
   the read CR opcode (0x35). Do not use the opcode if the controller
   does not support it.
 
 Aside from these main changes, there is the usual load of API updates,
 kdoc fixes, potential memory leaks fixes, etc.

2aa680df68 sound updates for 6.19-rc1
The majority of changes at this time were about ASoC with a lot of
 code refactoring works.  From the functionality POV, there aren't much
 to see, but we have a wide range of device-specific fixes and updates.
 Here are some highlights:
 
 - Continued ASoC API clean works, spanned over many files
 - Added a SoundWire SCDA generic class driver with regmap support
 - Enhancements and fixes for Cirrus, Intel, Maxim and Qualcomm.
 - Support for ASoC Allwinner A523, Mediatek MT8189, Qualcomm QCM2290,
   QRB2210 and SM6115, SpacemiT K1, and TI TAS2568, TAS5802, TAS5806,
   TAS5815, TAS5828 and TAS5830
 - Usual HD-audio and USB-audio quirks and fixups
 - Support for Onkyo SE-300PCIE, TASCAM IF-FW/DM MkII
 
 Some gpiolib changes for shared GPIOs are included along with this PR
 for covering ASoC drivers changes.

65db7a1f9c drm/i915/color: Add 3D LUT to color pipeline
Add helpers to program the 3D LUT registers and arm them.

LUT_3D_READY in LUT_3D_CLT is cleared off by the HW once
the LUT buffer is loaded into it's internal working RAM.
So by the time we try to load/commit new values, we expect
it to be cleared off. If not, log an error and return
without writing new values. Do it only when writing with MMIO.
There is no way to read register within DSB execution.

v2:
- Add information regarding LUT_3D_READY to commit message (Jani)
- Log error instead of a drm_warn and return without committing changes
  if 3DLUT HW is not ready to accept new values.
- Refactor intel_color_crtc_has_3dlut()

6f1e094fb6 drm/i915/color: Preserve sign bit when int_bits is Zero
When int_bits == 0, we lose the sign bit when we do the range check
and apply the mask.

Fix this by ensuring a minimum of one integer bit, which guarantees space
for the sign bit in fully fractional representations (e.g. S0.12)

83c8f7b5e1 mm/mm_init: Introduce a boot parameter for check_pages
Use-after-free and double-free bugs can be very difficult to track down.
The kernel is good at tracking these and preventing bad pages from being
used/created through simple checks gated behind "check_pages_enabled".

Currently, the only ways to enable this flag is by building with
CONFIG_DEBUG_VM, or as a side effect of other checks such as
init_on_{alloc, free}, page_poisoning, or debug_pagealloc among others.
These solutions are powerful, but may often be too coarse in balancing
the performance vs. safety that a user may want, particularly in
latency-sensitive production environments.

Introduce a new boot parameter "check_pages", which enables page checking
with no other side effects. It takes kstrbool-able inputs as an argument
(i.e. 0/1, true/false, on/off, ...). This patch is backwards-compatible;
setting CONFIG_DEBUG_VM still enables page checking.

1a7a7b80a2 drm/panel: novatek-nt35560: avoid on-stack device structure
A cleanup patch apparently by accident used a local device structure
instead of a pointer to one in the nt35560_read_id() function, causing
a warning about stack usage:

drivers/gpu/drm/panel/panel-novatek-nt35560.c: In function 'nt35560_read_id':
drivers/gpu/drm/panel/panel-novatek-nt35560.c:249:1: error: the frame size of 1296 bytes is larger than 1280 bytes [-Werror=frame-larger-than=]

Change this to a pointer as was liley intended here.

Merge tag 'drm-next-2025-12-03' of https://gitlab.freedesktop.org/drm/kernel

Pull drm updates from Dave Airlie:
 "There was a rather late merge of a new color pipeline feature, that
  some userspace projects are blocked on, and has seen a lot of work in
  amdgpu. This should have seen some time in -next. There is additional
  support for this for Intel, that if it arrives in the next day or two
  I'll pass it on in another pull request and you can decide if you want
  to take it.

  Highlights:
   - Arm Ethos NPU accelerator driver
   - new DRM color pipeline support

c196bf43d7 blk-mq: Abort suspend when wakeup events are pending
During system suspend, wakeup capable IRQs for block device can be
delayed, which can cause blk_mq_hctx_notify_offline() to hang
indefinitely while waiting for pending request to complete.
Skip the request waiting loop and abort suspend when wakeup events are
pending to prevent the deadlock.

71075d25ca blk-mq: add blk_rq_nr_bvec() helper
Add a new helper function blk_rq_nr_bvec() that returns the number of
bvecs in a request. This count represents the number of iterations
rq_for_each_bvec() would perform on a request.

Drivers need to pre-allocate bvec arrays before iterating through
a request's bvecs. Currently, they manually count bvecs using
rq_for_each_bvec() in a loop, which is repetitive. The new helper
centralizes this logic.

This pattern exists in loop and zloop drivers, where multi-bio requests
require copying bvecs into a contiguous array before creating
an iov_iter for file operations.

Update loop and zloop drivers to use the new helper, eliminating
duplicate code.

This patch also provides a clear API to avoid any potential misuse of
blk_nr_phys_segments() for calculating the bvecs since, one bvec can
have more than one segments and use of blk_nr_phys_segments() can
lead to extra memory allocation :-

[ 6155.673749] nullb_bio: 128K bio as ONE bvec: sector=0, size=131072
[ 6155.673846] null_blk: #### null_handle_data_transfer:1375
[ 6155.673850] null_blk: nr_bvec=1 blk_rq_nr_phys_segments=2
[ 6155.674263] null_blk: #### null_handle_data_transfer:1375
[ 6155.674267] null_blk: nr_bvec=1 blk_rq_nr_phys_segments=1

3e2cb9ee76 block: add IOC_PR_READ_RESERVATION ioctl
Add a Persistent Reservations ioctl to read the current reservation.
This calls the pr_ops->read_reservation() function that was previously
added in commit c787f1baa5 ("block: Add PR callouts for read keys and
reservation") but was only used by the in-kernel SCSI target so far.

The IOC_PR_READ_RESERVATION ioctl is necessary so that userspace
applications that rely on Persistent Reservations ioctls have a way of
inspecting the current state. Cluster managers and validation tests need
this functionality.

The pr_read_keys() interface has a u32 num_keys parameter. The NVMe

values that are too large to fit.

48f22f8093 block: enable per-cpu bio cache by default
Since after commit 12e4e8c7ab ("io_uring/rw: enable bio caches for
IRQ rw"), bio_put is safe for task and irq context, bio_alloc_bioset is
safe for task context and no one calls in irq context, so we can enable
per cpu bio cache by default.

Benchmarked with t/io_uring and ext4+nvme:
taskset -c 6 /root/fio/t/io_uring  -p0 -d128 -b4096 -s1 -c1 -F1 -B1 -R1
-X1 -n1 -P1  /mnt/testfile
base IOPS is 562K, patch IOPS is 574K. The CPU usage of bio_alloc_bioset
decrease from 1.42% to 1.22%.

The worst case is allocate bio in CPU A but free in CPU B, still use
t/io_uring and ext4+nvme:
base IOPS is 648K, patch IOPS is 647K.

Also use fio test ext4/xfs with libaio/sync/io_uring on null_blk and
nvme, no obvious performance regression.
