5f63e8a11e spi: spi-qpic-snand: handle 'use_ecc' parameter of qcom_spi_config_cw_read()
[ Upstream commit 9c45f95222 ]

During raw read, neither the status of the ECC correction nor the erased
state of the codeword gets checked by the qcom_spi_read_cw_raw() function,
so in case of raw access reading the corresponding registers via DMA is
superfluous.

Extend the qcom_spi_config_cw_read() function to evaluate the existing
(but actually unused) 'use_ecc' parameter, and configure reading only
the flash status register when ECC is not used.

With the change, the code gets in line with the corresponding part of
the config_nand_cw_read() function in the qcom_nandc driver.

929a89b3aa spi: loopback-test: Don't use %pK through printk
[ Upstream commit b832b19318 ]

In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d24 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.

Switch to the regular pointer formatting which is safer and
easier to reason about.
There are still a few users of %pK left, but these use it through seq_file,
for which its usage is safe.

30880e9df2 usb: gadget: f_fs: Fix epfile null pointer access after ep enable.
commit cfd6f1a7b4 upstream.

A race condition occurs when ffs_func_eps_enable() runs concurrently
with ffs_data_reset(). The ffs_data_clear() called in ffs_data_reset()
sets ffs->epfiles to NULL before resetting ffs->eps_count to 0, leading
to a NULL pointer dereference when accessing epfile->ep in
ffs_func_eps_enable() after successful usb_ep_enable().

The ffs->epfiles pointer is set to NULL in both ffs_data_clear() and
ffs_data_close() functions, and its modification is protected by the
spinlock ffs->eps_lock. And the whole ffs_func_eps_enable() function
is also protected by ffs->eps_lock.

Thus, add NULL pointer handling for ffs->epfiles in the
ffs_func_eps_enable() function to fix issues

commit 309e65d151 upstream.

Commit 9e36775c22 ("mfd: kempld: Remove custom DMI matching code")
removes the ability to load the driver if no matching system DMI data

4ddf729392 PM: sleep: Allow pm_restrict_gfp_mask() stacking
[ Upstream commit 35e4a69b20 ]

Allow pm_restrict_gfp_mask() to be called many times in a row to avoid
issues with calling dpm_suspend_start() when the GFP mask has been
already restricted.

Only the first invocation of pm_restrict_gfp_mask() will actually
restrict the GFP mask and the subsequent calls will warn if there is
a mismatch between the expected allowed GFP mask and the actual one.

Moreover, if pm_restrict_gfp_mask() is called many times in a row,
pm_restore_gfp_mask() needs to be called matching number of times in
a row to actually restore the GFP mask.  Calling it when the GFP mask
has not been restricted will cause it to warn.

This is necessary for the GFP mask restriction starting in
hibernation_snapshot() to continue throughout the entire hibernation
flow until it completes or it is aborted (either by a wakeup event or
by an error).

ef14be6774 cpuidle: governors: menu: Select polling state in some more cases
[ Upstream commit db86f55bf8 ]

A throughput regression of 11% introduced by commit 779b1a1cb1 ("cpuidle:
governors: menu: Avoid selecting states with too much latency") has been
reported and it is related to the case when the menu governor checks if
selecting a proper idle state instead of a polling one makes sense.

In particular, it is questionable to do so if the exit latency of the
idle state in question exceeds the predicted idle duration, so add a
check for that, which is sufficient to make the reported regression go
away, and update the related code comment accordingly.

41ec9e0f79 drm/amd/display: Don't program BLNDGAM_MEM_PWR_FORCE when CM low-power is disabled on DCN30
commit 382bd6a792 upstream.

Before commit 33056a97ae ("drm/amd/display: Remove double checks for
`debug.enable_mem_low_power.bits.cm`"), dpp3_program_blnd_lut(NULL)
checked the low-power debug flag before calling
dpp3_power_on_blnd_lut(false).

After commit 33056a97ae ("drm/amd/display: Remove double checks for
`debug.enable_mem_low_power.bits.cm`"), dpp3_program_blnd_lut(NULL)
unconditionally calls dpp3_power_on_blnd_lut(false). The BLNDGAM power
helper writes BLNDGAM_MEM_PWR_FORCE when CM low-power is disabled, causing
immediate SRAM power toggles instead of deferring at vupdate. This can
disrupt atomic color/LUT sequencing during transitions between
direct scanout and composition within gamescope's DRM backend on
Steam Deck OLED.

To fix this, leave the BLNDGAM power state unchanged when low-power is
disabled, matching dpp3_power_on_hdr3dlut and dpp3_power_on_shaper.

c940c473ef drm/amd: Check that VPE has reached DPM0 in idle handler
commit ba10f8d92a upstream.

[Why]
Newer VPE microcode has functionality that will decrease DPM level
only when a workload has run for 2 or more seconds.  If VPE is turned
off before this DPM decrease and the PMFW doesn't reset it when
power gating VPE, the SOC can get stuck with a higher DPM level.

This can happen from amdgpu's ring buffer test because it's a short
quick workload for VPE and VPE is turned off after 1s.

[How]
In idle handler besides checking fences are drained check PMFW version
to determine if it will reset DPM when power gating VPE.  If PMFW will
not do this, then check VPE DPM level. If it is not DPM0 reschedule
delayed work again until it is.

2606dfd971 drm/i915/dmc: Clear HRR EVT_CTL/HTP to zero on ADL-S
commit dc8aa0cb87 upstream.

On ADL-S the main DMC HRR event DMC_EVT_CTL/HTP are never
restored to their previous values during DC6 exit. This
angers assert_dmc_loaded(), and basically makes the HRR
handler unusable because we don't rewrite EVT_HTP when
enabling DMC events.

Let's just clear the HRR EVT_CTL/HTP to zero from the
beginnning so that the expected value matches the post-DC6
reality.

I suppose if we ever had actual use for HRR we'd have to both,
reject HRR+PSR, and reprogram EVT_HTP when enabling the event.
But for now we don't care about HRR so keeping both registers
zeroed is fine.

commit 926d002e6d upstream.

platform device driver data during bind() but failed to remove a partial
fix which had been added by commit 80805b62ea ("drm/mediatek: Fix
kobject put for component sub-drivers").

This results in a reference imbalance on component bind() failures and
on unbind() which could lead to a user-after-free.

Make sure to only drop the references after retrieving the driver data
by effectively reverting the previous partial fix.

Note that holding a reference to a device does not prevent its driver
data from going away so there is no point in keeping the reference.

effect for the first check.

Replace the barrier with a function which takes the spinlock.

In a past bug fix it was forgotten that entity access must be protected

54eebe7be0 drm/sched: avoid killing parent entity on child SIGKILL
commit 9e8b3201c7 upstream.

The DRM scheduler tracks who last uses an entity and when that process
is killed blocks all further submissions to that entity.

The problem is that we didn't track who initially created an entity, so
when a process accidently leaked its file descriptor to a child and
that child got killed, we killed the parent's entities.

Avoid that and instead initialize the entities last user on entity
creation. This also allows to drop the extra NULL check.

1e7eaf55ae s390/mm: Fix memory leak in add_marker() when kvrealloc() fails
commit 07ad45e06b upstream.

The function has a memory leak when kvrealloc() fails.
The function directly assigns NULL to the markers pointer, losing the
reference to the previously allocated memory. This causes kvfree() in
pt_dump_init() to free NULL instead of the leaked memory.

Fix by:
1. Using kvrealloc() uniformly for all allocations
2. Using a temporary variable to preserve the original pointer until
   allocation succeeds
3. Removing the error path that sets markers_cnt=0 to keep
   consistency between markers and markers_cnt

Found via static analysis and this is similar to commit 42378a9ca5

d4a8238e57 s390: Disable ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAP
commit 64e2f60f35 upstream.

As reported by Luiz Capitulino enabling HVO on s390 leads to reproducible
crashes. The problem is that kernel page tables are modified without
flushing corresponding TLB entries.

Even if it looks like the empty flush_tlb_all() implementation on s390 is
the problem, it is actually a different problem: on s390 it is not allowed
to replace an active/valid page table entry with another valid page table
entry without the detour over an invalid entry. A direct replacement may
lead to random crashes and/or data corruption.

In order to invalidate an entry special instructions have to be used
(e.g. ipte or idte). Alternatively there are also special instructions
available which allow to replace a valid entry with a different valid
entry (e.g. crdte or cspg).

Given that the HVO code currently does not provide the hooks to allow for
an implementation which is compliant with the s390 architecture
requirements, disable ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAP again, which is
basically a revert of the original patch which enabled it.

54f938d9f5 s390/pci: Avoid deadlock between PCI error recovery and mlx5 crdump
commit 0fd20f65df upstream.

Do not block PCI config accesses through pci_cfg_access_lock() when
executing the s390 variant of PCI error recovery: Acquire just
device_lock() instead of pci_dev_lock() as powerpc's EEH and
generig PCI AER processing do.

During error recovery testing a pair of tasks was reported to be hung:

No kernel log of the exact same error with an upstream kernel is
available - but the very same deadlock situation can be constructed there,
too:

- task: kmcheck
  mlx5_unload_one() tries to acquire devlink lock while the PCI error
  recovery code has set pdev->block_cfg_access by way of
  pci_cfg_access_lock()
- task: kworker
  mlx5_crdump_collect() tries to set block_cfg_access through
  pci_cfg_access_lock() while devlink_health_report() had acquired
  the devlink lock.

A similar deadlock situation can be reproduced by requesting a
crdump with
  > devlink health dump show pci/<BDF> reporter fw_fatal

while PCI error recovery is executed on the same <BDF> physical function
by mlx5_core's pci_error_handlers. On s390 this can be injected with
  > zpcictl --reset-fw <BDF>

Tests with this patch failed to reproduce that second deadlock situation,
the devlink command is rejected with "kernel answers: Permission denied" -
and we get a kernel log message of:

mlx5_core 1ed0:00:00.1: mlx5_crdump_collect:50:(pid 254382): crdump: failed to lock vsc gw err -5

because the config read of VSC_SEMAPHORE is rejected by the underlying
hardware.

Two prior attempts to address this issue have been discussed and
ultimately rejected [see link], with the primary argument that s390's
implementation of PCI error recovery is imposing restrictions that
neither powerpc's EEH nor PCI AER handling need. Tests show that PCI
error recovery on s390 is running to completion even without blocking
access to PCI config space.

the incorrect bus_context pointer (3rd argument) was used in
__devm_regmap_init_slimbus(). It should be just "slimbus" (which is equal

the first user of devm_regmap_init_slimbus() but we should fix it till
the point where __devm_regmap_init_slimbus() was introduced therefore
two "Fixes" tags.

29cce25a75 kbuild: align modinfo section for Secureboot Authenticode EDK2 compat
commit d50f210913 upstream.

Previously linker scripts would always generate vmlinuz that has sections
aligned. And thus padded (correct Authenticode calculation) and unpadded
calculation would be same. As in https://github.com/rhboot/pesign userspace
tool would produce the same authenticode digest for both of the following
commands:

    pesign --padding --hash --in ./arch/x86_64/boot/bzImage
    pesign --nopadding --hash --in ./arch/x86_64/boot/bzImage

The commit 3e86e4d74c ("kbuild: keep .modinfo section in
vmlinux.unstripped") added .modinfo section of variable length. Depending
on kernel configuration it may or may not be aligned.

All userspace signing tooling correctly pads such section to calculation
spec compliant authenticode digest.

However, if bzImage is not further processed and is attempted to be loaded
directly by EDK2 firmware, it calculates unpadded Authenticode digest and
fails to correct accept/reject such kernel builds even when propoer
Authenticode values are enrolled in db/dbx. One can say EDK2 requires
aligned/padded kernels in Secureboot.

Thus add ALIGN(8) to the .modinfo section, to esure kernels irrespective of
modinfo contents can be loaded by all existing EDK2 firmware builds.

80abadeaad block: make REQ_OP_ZONE_OPEN a write operation
commit 19de03b312 upstream.

A REQ_OP_OPEN_ZONE request changes the condition of a sequential zone of
a zoned block device to the explicitly open condition
(BLK_ZONE_COND_EXP_OPEN). As such, it should be considered a write
operation.

Change this operation code to be an odd number to reflect this. The
following operation numbers are changed to keep the numbering compact.

No problems were reported without this change as this operation has no
data. However, this unifies the zone operation to reflect that they
modify the device state and also allows strengthening checks in the
block layer, e.g. checking if this operation is not issued against a
read-only device.

87b4a83dc2 ACPI: fan: Use ACPI handle when retrieving _FST
commit 58764259eb upstream.

Usage of the ACPI device should be phased out in the future, as
the driver itself is now using the platform bus.

Replace any usage of struct acpi_device in acpi_fan_get_fst() to
allow users to drop usage of struct acpi_device.

Also extend the integer check to all three package elements.

ec18f6b2c7 drm/radeon: Remove calls to drm_put_dev()
[ Upstream commit 745bae76ac ]

Since the allocation of the drivers main structure was changed to

should be done by devres.

However, drm_put_dev() is still in the probe error and device remove
paths. When the driver fails to probe warnings like the following are
shown because devres is trying to drm_put_dev() after the driver
already did it.

0bf0e9b845 ASoC: fsl_sai: Fix sync error in consumer mode
[ Upstream commit b2dd1d0d32 ]

When configured for default synchronisation (Rx syncs to Tx) and the
SAI operates in consumer mode (clocks provided externally to Tx), a
synchronisation error occurs on Tx on the first attempt after device
initialisation when the playback stream is started while a capture
stream is already active. This results in channel shift/swap on the
playback stream.
Subsequent streams (ie after that first failing one) always work
correctly, no matter the order, with or without the other stream active.

This issue was observed (and fix tested) on an i.MX6UL board connected
to an ADAU1761 codec, where the codec provides both frame and bit clock
(connected to TX pins).

To fix this, always initialize the 'other' xCR4 and xCR5 registers when
we're starting a stream which is synced to the opposite one, irregardless
of the producer/consumer status.

af0a745250 dpll: spec: add missing module-name and clock-id to pin-get reply
[ Upstream commit 520ad9e969 ]

The dpll.yaml spec incorrectly omitted module-name and clock-id from the
pin-get operation reply specification, even though the kernel DPLL
implementation has always included these attributes in pin-get responses
since the initial implementation.

This spec inconsistency caused issues with the C YNL code generator.
The generated dpll_pin_get_rsp structure was missing these fields.

Fix the spec by adding module-name and clock-id to the pin-attrs reply
specification to match the actual kernel behavior.
