32a92f8c89 Convert more 'alloc_obj' cases to default GFP_KERNEL arguments
This converts some of the visually simpler cases that have been split
over multiple lines.  I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.

Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script.  I probably had made it a bit _too_ trivial.

So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.

The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

948a013a54 efi: Align unaccepted memory range to page boundary
The accept_memory() and range_contains_unaccepted_memory() functions
employ a "guard page" logic to prevent crashes with load_unaligned_zeropad().
This logic extends the range to be accepted (or checked) by one unit_size
if the end of the range is aligned to a unit_size boundary.

However, if the caller passes a range that is not page-aligned, the
'end' of the range might not be numerically aligned to unit_size, even
if it covers the last page of a unit. This causes the "if (!(end % unit_size))"
check to fail, skipping the necessary extension and leaving the next
unit unaccepted, which can lead to a kernel panic when accessed by
load_unaligned_zeropad().

Align the start address down and the size up to the nearest page
boundary before performing the unit_size alignment check. This ensures
that the guard unit is correctly added when the range effectively ends
on a unit boundary.

0862438c90 efi: Fix reservation of unaccepted memory table
The reserve_unaccepted() function incorrectly calculates the size of the
memblock reservation for the unaccepted memory table. It aligns the
size of the table, but fails to account for cases where the table's
starting physical address (efi.unaccepted) is not page-aligned.

If the table starts at an offset within a page and its end crosses into
a subsequent page that the aligned size does not cover, the end of the
table will not be reserved. This can lead to the table being overwritten
or inaccessible, causing a kernel panic in accept_memory().

This issue was observed when starting Intel TDX VMs with specific memory
sizes (e.g., > 64GB).

Fix this by calculating the end address first (including the unaligned
start) and then aligning it up, ensuring the entire range is covered
by the reservation.

Pull SoC devicetree updates from Arnd Bergmann:
 "There are a handful of new SoCs this time, all of these are more or
  less related to chips in a wider family:

   - SpacemiT Key Stone K3 is an 8-core risc-v chip, and the first
     widely available RVA23 implementation. Note that this is entirely
     unrelated with the similarly named Texas Instruments K3 chip family
     that follwed the TI Keystone2 SoC.

   - The Realtek Kent family of SoCs contains three chip models
     rtd1501s, rtd1861b and rtd1920s, and is related to their earlier
     Set-top-box and NAS products such as rtd1619, but is built on newer
     Arm Cortex-A78 cores.

   - The Qualcomm Milos family includes the Snapdragon 7s Gen 3 (SM7635)
     mobile phone SoC built around Armv9 Kryo cores of the Arm
     Cortex-A720 generation. This one is used in the Fairphone Gen 6

   - Qualcomm Kaanapali is a new SoC based around eight high performance
     Oryon CPU cores

   - NXP i.MX8QP and i.MX952 are both feature reduced versions of chips
     we already support, i.e. the i.MX8QM and i.MX952, with fewer CPU
     cores and I/O interfaces.

  As part of a cleanup, a number of SoC specific devicetree files got
  removed because they did not have a single board using the .dtsi files
  and they were never compile tested as a result: Samsung s3c6400, ST
  spear320s, ST stm32mp21xc/stm32mp23xc/stm32mp25xc, Renesas
  r8a779m0/r8a779m2/r8a779m4/r8a779m6/r8a779m7/r8a779m8/r8a779mb/
  r9a07g044c1/r9a07g044l1/r9a07g054l1/r9a09g047e37, and TI
  am3703/am3715. All of these could be restored easily if a new board
  gets merged.

  Broadcom/Cavium/Marvell ThunderX2 gets removed along with its only
  machine, as all remaining users are assumed to be using ACPI based
  firmware.

  A relatively small number of 43 boards get added this time, and almost
  all of them for arm64. Aside from the reference boards for the newly
  added SoCs, this includes:

   - Three server boards use 32-bit ASpeed BMCs

   - One more reference board for 32-bit Microchip LAN9668

   - 64-bit Arm single-board computers based on Amlogic s905y4, CIX
     sky1, NXP ls1028a/imx8mn/imx8mp/imx91/imx93/imx95, Qualcomm
     qcs6490/qrb2210 and Rockchip rk3568/rk3588s

   - Carrier board for SOMs using Intel agilex5, Marvell Armada 7020,
     NXP iMX8QP, Mediatek mt8370/mt8390 and rockchip rk3588

   - Two mobile phones using Snapdragon 845

   - A gaming device and a NAS box, both based on Rockchips rk356x

  On top of the newly added boards and SoCs, there is a lot of
  background activity going into cleanups, in particular towards getting
  a warning-free dtc build, and the usual work on adding support for
  more hardware on the previously added machines"

Pull ACPI updates from Rafael Wysocki:
 "This one is significantly larger than previous ACPI support pull
  requests because several significant updates have coincided in it.

  First, there is a routine ACPICA code update, to upstream version
  20251212, but this time it covers new ACPI 6.6 material that has not
  been covered yet. Among other things, it includes definitions of a few
  new ACPI tables and updates of some others, like the GICv5 MADT
  structures and ARM IORT IWB node definitions that are used for adding
  GICv5 ACPI probing on ARM (that technically is IRQ subsystem material,
  but it depends on the ACPICA changes, so it is included here). The
  latter alone adds a few hundred lines of new code.

  Second, there is an update of ACPI _OSC handling including a fix that
  prevents failures from occurring in some corner cases due to careless
  handling of _OSC error bits.

  On top of that, the "system resource" ACPI device objects with the
  PNP0C01 and PNP0C02 are now going to be handled by the ACPI core
  device enumeration code instead of handing them over to the legacy PNP
  system driver which causes device enumeration issues to occur. Some of
  those issues have been worked around in device drivers and elsewhere
  and those workarounds should not be necessary any more, so they are
  going away.

  Moreover, the time has come to convert all "core ACPI" device drivers
  that were still using struct acpi_driver objects for device binding
  into proper platform drivers that use struct platform_driver for this
  purpose. These updates are accompanied by some requisite core ACPI
  device enumeration code changes.

  Next, there are ACPI APEI updates, including changes to avoid excess
  overhead in the NMI handler and in SEA on the ARM side, changes to
  unify ACPI-based HW error tracing and logging, and changes to prevent
  APEI code from reaching out of its allocated memory.

  There are also some ACPI power management updates, mostly related to
  the ACPI cpuidle support in the processor driver, suspend-to-idle
  handling on systems with ACPI support and to ACPI PM of devices.

  In addition to the above, bugs are fixed and the code is cleaned up in
  assorted places all over.

  Specifics:

   - Update the ACPICA code in the kernel to upstream version 20251212
     which includes the following changes:
      * Add support for new ACPI table DTPR (Michal Camacho Romero)
      * Release objects with acpi_ut_delete_object_desc() (Zilin Guan)
      * Add UUIDs for Microsoft fan extensions and UUIDs associated with
        TPM 2.0 devices (Armin Wolf)
      * Fix NULL pointer dereference in acpi_ev_address_space_dispatch()
        (Alexey Simakov)
      * Add KEYP ACPI table definition (Dave Jiang)
      * Add support for the Microsoft display mux _OSI string (Armin
        Wolf)
      * Add definitions for the IOVT ACPI table (Xianglai Li)
      * Abort AML bytecode execution on AML_FATAL_OP (Armin Wolf)
      * Include all fields in subtable type1 for PPTT (Ben Horgan)
      * Add GICv5 MADT structures and Arm IORT IWB node definitions
        (Jose Marinho)
      * Update Parameter Block structure for RAS2 and add a new flag in
        Memory Affinity Structure for SRAT (Pawel Chmielewski)
      * Add _VDM (Voltage Domain) object (Pawel Chmielewski)

   - Add support for GICv5 ACPI probing on ARM which is based on the
     GICv5 MADT structures and ARM IORT IWB node definitions recently
     added to ACPICA (Lorenzo Pieralisi)

   - Rework ACPI PM notification setup for PCI root buses and modify the
     ACPI PM setup for devices to register wakeup source objects under
     physical (that is, PCI, platform, etc.) devices instead of doing
     that under their ACPI companions (Rafael Wysocki)

   - Adjust debug messages regarding postponed ACPI PM printed during
     system resume to be more accurate (Rafael Wysocki)

   - Remove dead code from lps0_device_attach() (Gergo Koteles)

   - Start to invoke Microsoft Function 9 (Turn On Display) of the Low-
     Power S0 Idle (LPS0) _DSM in the suspend-to-idle resume flow on
     systems with ACPI LPS0 support to address a functional issue on
     Lenovo Yoga Slim 7i Aura (15ILL9), where system fans and keyboard
     backlights fail to resume after suspend (Jakob Riemenschneider)

   - Add sysfs attribute cid for exposing _CID lists under ACPI device
     objects (Rafael Wysocki)

   - Replace sprintf() with sysfs_emit() in all of the core ACPI sysfs
     interface code (Sumeet Pawnikar)

   - Use acpi_get_local_u64_address() in the code implementing ACPI
     support for PCI to evaluate _ADR instead of evaluating that object
     directly (Andy Shevchenko)

   - Add JWIPC JVC9100 to irq1_level_low_skip_override[] to unbreak
     serial IRQs on that system (Ai Chao)

   - Fix handling of _OSC errors in acpi_run_osc() to avoid failures on
     systems where _OSC error bits are set even though the _OSC return
     buffer contains acknowledged feature bits (Rafael Wysocki)

   - Clean up and rearrange \_SB._OSC handling for general platform
     features and USB4 features to avoid code duplication and
     unnecessary memory management overhead (Rafael Wysocki)

   - Make the ACPI core device enumeration code handle PNP0C01 and
     PNP0C02 ("system resource") device objects directly instead of
     letting the legacy PNP system driver handle them to avoid device
     enumeration issues on systems where PNP0C02 is present in the _CID
     list under ACPI device objects with a _HID matching a proper device
     driver in Linux (Rafael Wysocki)

   - Drop workarounds for the known device enumeration issues related to
     _CID lists containing PNP0C02 (Rafael Wysocki)

   - Drop outdated comment regarding removed function in the ACPI-based
     device enumeration code (Julia Lawall)

   - Make PRP0001 device matching work as expected for ACPI device
     objects using it as a _HID for board development and similar
     purposes (Kartik Rajput)

   - Use async schedule function in acpi_scan_clear_dep_fn() to avoid
     races with user space initialization on some systems (Yicong Yang)

   - Add a piece of documentation explaining why binding drivers
     directly to ACPI device objects is not a good idea in general and
     why it is desirable to convert drivers doing so into proper
     platform drivers that use struct platform_driver for device binding
     (Rafael Wysocki)

   - Convert multiple "core ACPI" drivers, including the NFIT ACPI
     device driver, the generic ACPI button drivers, the generic ACPI
     thermal zone driver, the ACPI hardware event device (HED) driver,
     the ACPI EC driver, the ACPI SMBUS HC driver, the ACPI Smart
     Battery Subsystem (SBS) driver, and the ACPI backlight (video)
     driver to proper platform drivers that use struct platform_driver
     for device binding (Rafael Wysocki)

   - Use acpi_get_local_u64_address() in the ACPI backlight (video)
     driver to evaluate _ADR instead of evaluating that object directly
     (Andy Shevchenko)

   - Convert the generic ACPI battery driver to a proper platform driver
     using struct platform_driver for device binding (Rafael Wysocki)

   - Fix incorrect charging status when current is zero in the generic
     ACPI battery driver (Ata İlhan Köktürk)

   - Use LIST_HEAD() for initializing a stack-allocated list in the
     generic ACPI watchdog device driver (Can Peng)

   - Rework the ACPI idle driver initialization to register it directly
     from the common initialization code instead of doing that from a
     CPU hotplug "online" callback and clean it up (Huisong Li, Rafael
     Wysocki)

   - Fix a possible NULL pointer dereference in
     acpi_processor_errata_piix4() (Tuo Li)

   - Make read-only array non_mmio_desc[] static const (Colin Ian King)

   - Prevent the APEI GHES support code on ARM from accessing memory out
     of bounds or going past the ARM processor CPER record buffer (Mauro
     Carvalho Chehab)

   - Prevent cper_print_fw_err() from dumping the entire memory on
     systems with defective firmware (Mauro Carvalho Chehab)

   - Improve ghes_notify_nmi() status check to avoid unnecessary
     overhead in the NMI handler by carrying out all of the requisite
     preparations and the NMI registration time (Tony Luck)

   - Refactor the GHES driver by extracting common functionality into
     reusable helper functions to reduce code duplication and improve
     the ghes_notify_sea() status check in analogy with the previous
     ghes_notify_nmi() status check improvement (Shuai Xue)

   - Make ELOG and GHES log and trace consistently and support the CPER
     CXL protocol analogously (Fabio De Francesco)

   - Disable KASAN instrumentation in the APEI GHES driver when compile
     testing with clang < 18 (Nathan Chancellor)

   - Let ghes_edac be the preferred driver to load on __ZX__ and _BYO_
     systems by extending the platform detection list in the APEI GHES
     driver (Tony W Wang-oc)

   - Clean up cppc_perf_caps and cppc_perf_ctrls structs and rename EPP
     constants for clarity in the ACPI CPPC library (Sumit Gupta)"

ASoC: Updates for v7.0

This release is almost all abut driers, there's very little core work
here, although some of that driver work is in more generic areas like
SDCA and SOF:

 - Generic SDCA support for reporting jack events.
 - Continuing platform support, cleanup and feature improements for the
   AMD, Intel, Qualcomm and SOF code.
 - Platform description improvements for the Cirrus drivers.
 - Support for NXP i.MX952, Realtek RT1320 and RT5575, and Sophogo
   CV1800B.

We also pulled in one small SPI API update and some more substantial
regmap work (cache description improvements) for use in drivers.

10db9f6899 firmware: cs_dsp: rate-limit log messages in KUnit builds
Use the dev_*_ratelimit() macros if the cs_dsp KUnit tests are enabled
in the build, and allow the KUnit tests to disable message output.

Some of the KUnit tests cause a very large number of log messages from
cs_dsp, because the tests perform many different test cases. This could
cause some lines to be dropped from the kernel log. Dropped lines can
prevent the KUnit wrappers from parsing the ktap output in the dmesg log.

The KUnit builds of cs_dsp export three bools that the KUnit tests can
use to entirely disable log output of err, warn and info messages. Some
tests have been updated to use this, replacing the previous fudge of a
usleep() in the exit handler of each test. We don't necessarily want to
disable all log messages if they aren't expected to be excessive,
so the rate-limiting allows leaving some logging enabled.

The rate-limited macros are not used in normal builds because it is not
appropriate to rate-limit every message. That could cause important
messages to be dropped, and there wouldn't be such a high rate of
messages in normal operation.

Qualcomm driver updates for v6.20

Support multiple wait queues in the SCM firmware interface and provide
discovery of the wait queue interrupt to deal with the cases where
bootloader didn't patch the DeviceTree with the IRQ information.

Refactor the MDT loader and the SCM driver's peripheral authentication
service interface and introduce support for passing a remoteproc
resource table to the firmware. The remoteproc patches that uses this
and uses this to configure the IOMMU are included here due to
bidirectional dependencies. The end result is remoteproc support on the
Glymur platform.

Enable QSEECOM and thereby UEFI variable access, on the Surface Pro 11.

Make the QMI interface endianness aware, to support ath1Xk on big endian
machines.

Add the Glymur support in LLCC driver.

3. Reduce duplicated boilerplate in pinctrl and related protocols by
   consolidating validation and lookup logic in protocol get info helpers.

4. Refactor reset protocol domain handling by introducing a shared lookup
   helper, ensuring consistent validation and error reporting.

5. Fix potential undefined behaviour by properly initializing pointers

Removing hex.h from kernel.h means that 36K C source files don't have to
pay the price of parsing hex.h for the roughly 120 C source files that
need it.

This change has been build-tested with allmodconfig on most ARCHes.  Also,
all users/callers of <linux/hex.h> in the entire source tree have been
updated if needed (if not already #included).

6ac433f8b2 mm: rename cpu_bitmap field to flexible_array
The cpu_bitmap flexible array now contains more than just the cpu_bitmap. 
In preparation for changing the static mm_struct definitions to cover for
the additional space required, change the cpu_bitmap type from "unsigned
long" to "char", require an unsigned long alignment of the flexible array,
and rename the field from "cpu_bitmap" to "flexible_array".

Introduce the MM_STRUCT_FLEXIBLE_ARRAY_INIT macro to statically initialize
the flexible array.  This covers the init_mm and efi_mm static
definitions.

This is a preparation step for fixing the missing mm_cid size for static
mm_struct definitions.

55cc6fe571 EFI/CPER: don't dump the entire memory region
The current logic at cper_print_fw_err() doesn't check if the
error record length is big enough to handle offset. On a bad firmware,
if the ofset is above the actual record, length -= offset will
underflow, making it dump the entire memory.

The end result can be:

 - the logic taking a lot of time dumping large regions of memory;
 - data disclosure due to the memory dumps;
 - an OOPS, if it tries to dump an unmapped memory region.

Fix it by checking if the section length is too small before doing
a hex dump.

eae21beecb EFI/CPER: don't go past the ARM processor CPER record buffer
There's a logic inside GHES/CPER to detect if the section_length
is too small, but it doesn't detect if it is too big.

Currently, if the firmware receives an ARM processor CPER record
stating that a section length is big, kernel will blindly trust
section_length, producing a very long dump. For instance, a 67
bytes record with ERR_INFO_NUM set 46198 and section length
set to 854918320 would dump a lot of data going a way past the
firmware memory-mapped area.

Fix it by adding a logic to prevent it to go past the buffer
if ERR_INFO_NUM is too big, making it report instead:

	[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 1
	[Hardware Error]: event severity: recoverable
	[Hardware Error]:  Error 0, type: recoverable
	[Hardware Error]:   section_type: ARM processor error
	[Hardware Error]:   MIDR: 0xff304b2f8476870a
	[Hardware Error]:   section length: 854918320, CPER size: 67
	[Hardware Error]:   section length is too big

8b9d2050cf firmware: qcom_scm: Add qcom_scm_pas_get_rsc_table() to get resource table
Qualcomm remote processor may rely on Static and Dynamic resources for
it to be functional. Static resources are fixed like for example,
memory-mapped addresses required by the subsystem and dynamic
resources, such as shared memory in DDR etc., are determined at
runtime during the boot process.

For most of the Qualcomm SoCs, when run with Gunyah or older QHEE
hypervisor, all the resources whether it is static or dynamic, is
managed by the hypervisor. Dynamic resources if it is present for a
remote processor will always be coming from secure world via SMC call
while static resources may be present in remote processor firmware
binary or it may be coming qcom_scm_pas_get_rsc_table() SMC call along
with dynamic resources.

Some of the remote processor drivers, such as video, GPU, IPA, etc., do
not check whether resources are present in their remote processor
firmware binary. In such cases, the caller of this function should set
input_rt and input_rt_size as NULL and zero respectively. Remoteproc
framework has method to check whether firmware binary contain resources
or not and they should be pass resource table pointer to input_rt and
resource table size to input_rt_size and this will be forwarded to
TrustZone for authentication. TrustZone will then append the dynamic
resources and return the complete resource table in the passed output
buffer.

More about documentation on resource table format can be found in
include/linux/remoteproc.h

4a7d6a78fb firmware: qcom_scm: Add a prep version of auth_and_reset function
For memory passed to TrustZone (TZ), it must either be part of a pool
registered with TZ or explicitly registered via SHMbridge SMC calls.
When Gunyah hypervisor is present, PAS SMC calls from Linux running at
EL1 are trapped by Gunyah running @ EL2, which handles SHMbridge
creation for both metadata and remoteproc carveout memory before
invoking the calls to TZ.

On SoCs running with a non-Gunyah-based hypervisor, Linux must take
responsibility for creating the SHM bridge before invoking PAS SMC
calls. For the auth_and_reset() call, the remoteproc carveout memory
must first be registered with TZ via a SHMbridge SMC call and once
authentication and reset are complete, the SHMbridge memory can be
deregistered.

Introduce qcom_scm_pas_prepare_and_auth_reset(), which sets up the SHM
bridge over the remoteproc carveout memory when Linux operates at EL2.
This behavior is indicated by a new field added to the PAS context data
structure. The function then invokes the auth_and_reset SMC call.

ccb7bde5f7 firmware: qcom_scm: Introduce PAS context allocator helper function
When the Peripheral Authentication Service (PAS) method runs on a SoC
where Linux operates at EL2 (i.e., without the Gunyah hypervisor), the
reset sequences are handled by TrustZone. In such cases, Linux must
perform additional steps before invoking PAS SMC calls, such as creating
a SHM bridge. Therefore, PAS SMC calls require awareness and handling of
these additional steps when Linux runs at EL2.

To support this, there is a need for a data structure that can be
initialized prior to invoking any SMC or MDT functions. This structure
allows those functions to determine whether they are operating in the
presence or absence of the Gunyah hypervisor and behave accordingly.

Currently, remoteproc and non-remoteproc subsystems use different
variants of the MDT loader helper API, primarily due to differences in
metadata context handling. Remoteproc subsystems retain the metadata
context until authentication and reset are completed, while
non-remoteproc subsystems (e.g., video, graphics, IPA, etc.) do not
retain the metadata context and can free it within the
qcom_scm_pas_init() call by passing a NULL context parameter and due to
these differences, it is not possible to extend metadata context
handling to support remoteproc and non remoteproc subsystem use PAS
operations, when Linux operates at EL2.

Add PAS context data structure allocator helper function.

69054348cc firmware: qcom_scm: Rename peripheral as pas_id
Peripheral and pas_id refers to unique id for a subsystem and used only
when peripheral authentication service from secure world is utilized.

Lets rename peripheral to pas_id to reflect closer to its meaning.
