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.

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.

regmap: Updates for v6.19
Another small update for regmap, we have one new feature plus a little
bit of cleanup:
- Support for sparseness information in the flat cache, allowing users
that really need the performance properties it provides to benefit
from the interface and startup time improvements that sparsness provides
without needing to go all the way to a more fancy data structure.
- Cleanup work from Andy Shevchenko, refactoring the cache interface
in preparation for some future stuff he's working on.

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.

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.

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() Also remove Gen10 check (Suraj) v3: - Addressed review comments (Suraj) Reviewed-by: Suraj Kandpal <suraj.kandpal@intel.com> Signed-off-by: Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com> Signed-off-by: Uma Shankar <uma.shankar@intel.com> Link: https://patch.msgid.link/20251203085211.3663374-15-uma.shankar@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com> |

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.

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.

KVM: nSVM: Set exit_code_hi to -1 when synthesizing SVM_EXIT_ERR (failed VMRUN)
Set exit_code_hi to -1u as a temporary band-aid to fix a long-standing
(effectively since KVM's inception) bug where KVM treats the exit code as
a 32-bit value, when in reality it's a 64-bit value. Per the APM, offset
0x70 is a single 64-bit value:
070h 63:0 EXITCODE
And a sane reading of the error values defined in "Table C-1. SVM Intercept
Codes" is that negative values use the full 64 bits:
–1 VMEXIT_INVALID Invalid guest state in VMCB.
–2 VMEXIT_BUSYBUSY bit was set in the VMSA
–3 VMEXIT_IDLE_REQUIREDThe sibling thread is not in an idle state
-4 VMEXIT_INVALID_PMC Invalid PMC state
And that interpretation is confirmed by testing on Milan and Turin (by
setting bits in CR0[63:32] to generate VMEXIT_INVALID on VMRUN).
Furthermore, Xen has treated exitcode as a 64-bit value since HVM support
was adding in 2006 (see Xen commit d1bd157fbc ("Big merge the HVM
full-virtualisation abstractions.")).

KVM: nSVM: Clear exit_code_hi in VMCB when synthesizing nested VM-Exits
Explicitly clear exit_code_hi in the VMCB when synthesizing "normal" nested VM-Exits, as the full exit code is a 64-bit value (spoiler alert), and all exit codes for non-failing VMRUN use only bits 31:0.

net/mlx5: Fix double unregister of HCA_PORTS component
Clear hca_devcom_comp in device's private data after unregistering it in
LAG teardown. Otherwise a slightly lagging second pass through
mlx5_unload_one() might try to unregister it again and trip over
use-after-free.
On s390 almost all PCI level recovery events trigger two passes through
mxl5_unload_one() - one through the poll_health() method and one through
mlx5_pci_err_detected() as callback from generic PCI error recovery.
While testing PCI error recovery paths with more kernel debug features
enabled, this issue reproducibly led to kernel panics with the following
call chain:
Unable to handle kernel pointer dereference in virtual kernel address space

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.

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 Reviewed-by: Niklas Cassel <cassel@kernel.org> Signed-off-by: Chaitanya Kulkarni <ckulkarnilinux@gmail.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk> |

io_uring/io-wq: always retry worker create on ERESTART*
If a task has a pending signal when create_io_thread() is called,
copy_process() will return -ERESTARTNOINTR. io_should_retry_thread()
will request a retry of create_io_thread() up to WORKER_INIT_LIMIT = 3
times. If all retries fail, the io_uring request will fail with
ECANCELED.
Commit 3918315c5dc ("io-wq: backoff when retrying worker creation")
added a linear backoff to allow the thread to handle its signal before
the retry. However, a thread receiving frequent signals may get unlucky
and have a signal pending at every retry. Since the userspace task
doesn't control when it receives signals, there's no easy way for it to
prevent the create_io_thread() failure due to pending signals. The task
may also lack the information necessary to regenerate the canceled SQE.
So always retry the create_io_thread() on the ERESTART* errors,
analogous to what a fork() syscall would do. EAGAIN can occur due to
various persistent conditions such as exceeding RLIMIT_NPROC, so respect
the WORKER_INIT_LIMIT retry limit for EAGAIN errors.

io_uring/poll: correctly handle io_poll_add() return value on update
When the core of io_uring was updated to handle completions
consistently and with fixed return codes, the POLL_REMOVE opcode
with updates got slightly broken. If a POLL_ADD is pending and
then POLL_REMOVE is used to update the events of that request, if that
update causes the POLL_ADD to now trigger, then that completion is lost
and a CQE is never posted.
Additionally, ensure that if an update does cause an existing POLL_ADD
to complete, that the completion value isn't always overwritten with
-ECANCELED. For that case, whatever io_poll_add() set the value to
should just be retained.
