asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

Add compulsory device tree support to the Cirrus ep93xx ARMv4 platform.
- select PINCTRL_EP93xx
- select COMMON_CLK_EP93XX, as clock driver moved out of platform code
- select ARCH_HAS_RESET_CONTROLLER
Select ARM_ATAG_DTB_COMPAT to update device tree with information
about memory passed from bootloader.
We have to leave all MACH options as they are used for board checking
before decomp, to turn off watchdog and ethernet DMA.

Prepare ep93xx SOC gpio to convert into device tree driver:
- dropped banks and legacy defines
- split AB IRQ and make it shared
We are relying on IRQ number information A, B ports have single shared
IRQ, while F port have dedicated IRQ for each line.
Also we had to split single ep93xx platform_device into multiple, one
for each port, without this we can't do a full working transition from
legacy platform code into device tree capable. All GPIO_LOOKUP were
change to match new chip namings.

The psc->div[] array has psc->num_div elements. These values come from
when we call clk_hw_register_div(). It's adc_divisors and
ARRAY_SIZE(adc_divisors)) and so on. So this condition needs to be >=
instead of > to prevent an out of bounds read.

Pull i2c updates from Wolfram Sang:
"I2C core:
- finally remove the I2C_COMPAT symbol after 15 years of deprecation
- lock client addresses during initialization to prevent race
conditions between different kinds of instantiation
- use scoped foreach OF child loops
- testunit cleanups and documentation improvements, as well as two
new tests, one for repeated start and one for triggering SMBusAlert
interrupts
I2C host drivers:
- DesignWare and Renesas I2C driver updates.
The first has has undergone through a series of cleanups that have
been sent to the mailing list a year ago for the first time and
finally get merged in this pull request. They are many, from typos
(e.g. i2/i2c), to cosmetics, to refactoring (e.g. move inline
functions to librarieas) and many others.
- all the DesignWare Kconfig options have been grouped under the
I2C_DESIGNWARE_CORE and this required some adaptation in many of
the kernel configuration files for different arm and mips boards
Cleanups:
- improve the exit path in the runtime resume function for the
Qualcomm Geni platform
- get rid of the unused "target_addr" parameter in the Intel LJCA
driver
- intialize the restart_flag in the MediaTek controller in one single
place
- constify a few global data structures in the virtio driver
- simplify the bus speed handling in the Renesas driver init function
making it more readable
- improved probe function of the Renesas R-Car driver
- switch the iMX/MXC driver to use RUNTIME_PM_OPS() instead of
SET_RUNTIME_PM_OPS()
- iMX/MXC driver cleanups
- use devm_clk_get_enabled() to simplify the Renesas EMEV2, Ingenic
and MPC drivers
Refactoring:
- Fix a potential out of boundary array access in the Nuvoton driver.
This is not a bug fix because the issue could never occur due to
hardware not having the properties listed in the array. The change
makes the driver more future proof and, at the same time, silences
code analyzers.
Improvements:
- several patches improving the runtime power management handling of
the Renesas I2C (riic) driver
- use a more descriptive adapter name in the Intel i801 driver to
show the presence of the IDF feature
- kill pending transactions when irq's can't complete their handling
in the Intel Denverton (ismt) driver, triggering a timeout
New Feature:
- support fast mode plus in the Renesas I2C (riic) driver
New support:
- Added support for:
- Renesas R9A08G045
- Rockchip RK3576
- KEBA I2C
- Theobroma Systems Mule Multiplexer.
- new i2c-keba.c driver
- new driver for The Mule i2c multiplexer
Core I2C framework:
- move runtime PM functions in order to allow them to be accessed
during device add
Devicetree:
- nVidia and Qualcomm binding improvements
- get rid of redundant "multi-master" property in the aspeed binding
- convert i2c-sprd binding to YAML
AT24 updates:
- document a new model from giantec in DT bindings"

The dependency handling of the Synopsys DesignWare I2C
adapter drivers is going to be changed so that the glue
drivers for the PCI and platform buses depend on
I2C_DESIGNWARE_CORE.

LPC32XX connects few of its peripherals to pl08x DMA thru a multiplexer,
this driver allows to route a signal request line thru the multiplexer for
given peripheral.

Pull 'struct fd' updates from Al Viro:
"Just the 'struct fd' layout change, with conversion to accessor
helpers"
* tag 'pull-stable-struct_fd' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
add struct fd constructors, get rid of __to_fd()

introduce fd_file(), convert all accessors to it.

For any changes of struct fd representation we need to
turn existing accesses to fields into calls of wrappers.
Accesses to struct fd::flags are very few (3 in linux/file.h,
1 in net/socket.c, 3 in fs/overlayfs/file.c and 3 more in
explicit initializers).
Those can be dealt with in the commit converting to
new layout; accesses to struct fd::file are too many for that.
This commit converts (almost) all of f.file to
fd_file(f). It's not entirely mechanical ('file' is used as
a member name more than just in struct fd) and it does not
even attempt to distinguish the uses in pointer context from
those in boolean context; the latter will be eventually turned
into a separate helper (fd_empty()).
NOTE: mass conversion to fd_empty(), tempting as it
might be, is a bad idea; better do that piecewise in commit
that convert from fdget...() to CLASS(...).

Patch series "treewide: add missing MODULE_DESCRIPTION() macros".
Since commit 1fffe7a34c89 ("script: modpost: emit a warning when the
description is missing"), a module without a MODULE_DESCRIPTION() will
result in a warning when built with make W=1.
Recently, multiple developers have been eradicating these warnings
treewide, and I personally submitted almost 300 patches over the past few
months. Almost all of my patches landed by 6.11-rc1, either by being
merged in a 6.10-rc or by being merged in the 6.11 merge window. However,
a few of my patches did not land.
This patch (of 5):
With ARCH=arm and CONFIG_KERNEL_MODE_NEON=y, make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in arch/arm/lib/xor-neon.o
Add the missing invocation of the MODULE_DESCRIPTION() macro.

Pull MM updates from Andrew Morton:
"Along with the usual shower of singleton patches, notable patch series
in this pull request are:
- "Align kvrealloc() with krealloc()" from Danilo Krummrich. Adds
consistency to the APIs and behaviour of these two core allocation
functions. This also simplifies/enables Rustification.
- "Some cleanups for shmem" from Baolin Wang. No functional changes -
mode code reuse, better function naming, logic simplifications.
- "mm: some small page fault cleanups" from Josef Bacik. No
functional changes - code cleanups only.
- "Various memory tiering fixes" from Zi Yan. A small fix and a
little cleanup.
- "mm/swap: remove boilerplate" from Yu Zhao. Code cleanups and
simplifications and .text shrinkage.
- "Kernel stack usage histogram" from Pasha Tatashin and Shakeel
Butt. This is a feature, it adds new feilds to /proc/vmstat such as
$ grep kstack /proc/vmstat
kstack_1k 3
kstack_2k 188
kstack_4k 11391
kstack_8k 243
kstack_16k 0
which tells us that 11391 processes used 4k of stack while none at
all used 16k. Useful for some system tuning things, but
partivularly useful for "the dynamic kernel stack project".
- "kmemleak: support for percpu memory leak detect" from Pavel
Tikhomirov. Teaches kmemleak to detect leaksage of percpu memory.
- "mm: memcg: page counters optimizations" from Roman Gushchin. "3
independent small optimizations of page counters".
- "mm: split PTE/PMD PT table Kconfig cleanups+clarifications" from
David Hildenbrand. Improves PTE/PMD splitlock detection, makes
powerpc/8xx work correctly by design rather than by accident.
- "mm: remove arch_make_page_accessible()" from David Hildenbrand.
Some folio conversions which make arch_make_page_accessible()
unneeded.
- "mm, memcg: cg2 memory{.swap,}.peak write handlers" fro David
Finkel. Cleans up and fixes our handling of the resetting of the
cgroup/process peak-memory-use detector.
- "Make core VMA operations internal and testable" from Lorenzo
Stoakes. Rationalizaion and encapsulation of the VMA manipulation
APIs. With a view to better enable testing of the VMA functions,
even from a userspace-only harness.
- "mm: zswap: fixes for global shrinker" from Takero Funaki. Fix
issues in the zswap global shrinker, resulting in improved
performance.
- "mm: print the promo watermark in zoneinfo" from Kaiyang Zhao. Fill
in some missing info in /proc/zoneinfo.
- "mm: replace follow_page() by folio_walk" from David Hildenbrand.
Code cleanups and rationalizations (conversion to folio_walk())
resulting in the removal of follow_page().
- "improving dynamic zswap shrinker protection scheme" from Nhat
Pham. Some tuning to improve zswap's dynamic shrinker. Significant
reductions in swapin and improvements in performance are shown.
- "mm: Fix several issues with unaccepted memory" from Kirill
Shutemov. Improvements to the new unaccepted memory feature,
- "mm/mprotect: Fix dax puds" from Peter Xu. Implements mprotect on
DAX PUDs. This was missing, although nobody seems to have notied
yet.
- "Introduce a store type enum for the Maple tree" from Sidhartha
Kumar. Cleanups and modest performance improvements for the maple
tree library code.
- "memcg: further decouple v1 code from v2" from Shakeel Butt. Move
more cgroup v1 remnants away from the v2 memcg code.
- "memcg: initiate deprecation of v1 features" from Shakeel Butt.
Adds various warnings telling users that memcg v1 features are
deprecated.
- "mm: swap: mTHP swap allocator base on swap cluster order" from
Chris Li. Greatly improves the success rate of the mTHP swap
allocation.
- "mm: introduce numa_memblks" from Mike Rapoport. Moves various
disparate per-arch implementations of numa_memblk code into generic
code.
- "mm: batch free swaps for zap_pte_range()" from Barry Song. Greatly
improves the performance of munmap() of swap-filled ptes.
- "support large folio swap-out and swap-in for shmem" from Baolin
Wang. With this series we no longer split shmem large folios into
simgle-page folios when swapping out shmem.
- "mm/hugetlb: alloc/free gigantic folios" from Yu Zhao. Nice
performance improvements and code reductions for gigantic folios.
- "support shmem mTHP collapse" from Baolin Wang. Adds support for

Patch series "mm: Care about shadow stack guard gap when getting an
unmapped area", v2.
As covered in the commit log for c44357c2e76b ("x86/mm: care about shadow
stack guard gap during placement") our current mmap() implementation does
not take care to ensure that a new mapping isn't placed with existing
mappings inside it's own guard gaps. This is particularly important for
shadow stacks since if two shadow stacks end up getting placed adjacent to
each other then they can overflow into each other which weakens the
protection offered by the feature.
On x86 there is a custom arch_get_unmapped_area() which was updated by the
above commit to cover this case by specifying a start_gap for allocations
with VM_SHADOW_STACK. Both arm64 and RISC-V have equivalent features and
use the generic implementation of arch_get_unmapped_area() so let's make
the equivalent change there so they also don't get shadow stack pages
placed without guard pages. The arm64 and RISC-V shadow stack
implementations are currently on the list:
https://lore.kernel.org/r/20240829-arm64-gcs-v12-0-42fec94743
https://lore.kernel.org/lkml/20240403234054.2020347-1-debug@rivosinc.com/
Given the addition of the use of vm_flags in the generic implementation we
also simplify the set of possibilities that have to be dealt with in the
core code by making arch_get_unmapped_area() take vm_flags as standard.
This is a bit invasive since the prototype change touches quite a few
architectures but since the parameter is ignored the change is
straightforward, the simplification for the generic code seems worth it.
This patch (of 3):
When we introduced arch_get_unmapped_area_vmflags() in 961148704acd ("mm:
introduce arch_get_unmapped_area_vmflags()") we did so as part of properly
supporting guard pages for shadow stacks on x86_64, which uses a custom
arch_get_unmapped_area(). Equivalent features are also present on both
arm64 and RISC-V, both of which use the generic implementation of
arch_get_unmapped_area() and will require equivalent modification there.
Rather than continue to deal with having two versions of the functions
let's bite the bullet and have all implementations of
arch_get_unmapped_area() take vm_flags as a parameter.
The new parameter is currently ignored by all implementations other than
x86. The only caller that doesn't have a vm_flags available is
mm_get_unmapped_area(), as for the x86 implementation and the wrapper used
on other architectures this is modified to supply no flags.
No functional changes.

Patch series "mm: split PTE/PMD PT table Kconfig cleanups+clarifications".
This series is a follow up to the fixes:
"[PATCH v1 0/2] mm/hugetlb: fix hugetlb vs. core-mm PT locking"
When working on the fixes, I wondered why 8xx is fine (-> never uses split
PT locks) and how PT locking even works properly with PMD page table
sharing (-> always requires split PMD PT locks).
Let's improve the split PT lock detection, make hugetlb properly depend on
it and make 8xx bail out if it would ever get enabled by accident.
As an alternative to patch #3 we could extend the Kconfig
SPLIT_PTE_PTLOCKS option from patch #2 -- but enforcing it closer to the
code that actually implements it feels a bit nicer for documentation
purposes, and there is no need to actually disable it because it should
always be disabled (!SMP).
Did a bunch of cross-compilations to make sure that split PTE/PMD PT locks
are still getting used where we would expect them.
[1] https://lkml.kernel.org/r/20240725183955.2268884-1-david@redhat.com
This patch (of 3):
Let's clean that up a bit and prepare for depending on
CONFIG_SPLIT_PMD_PTLOCKS in other Kconfig options.
More cleanups would be reasonable (like the arch-specific "depends on" for
CONFIG_SPLIT_PTE_PTLOCKS), but we'll leave that for another day.

DMA ops are a helper for architectures and not for drivers to override
the DMA implementation.
Unfortunately driver authors keep ignoring this. Make the fact more
clear by renaming the symbol to ARCH_HAS_DMA_OPS and having the two drivers
overriding their dma_ops depend on that. These drivers should probably be
marked broken, but we can give them a bit of a grace period for that.

Pull SoC ARM platform updates from Arnd Bergmann:
"Most of these updates are for removing dead code on the Samsung S3C,
NXP i.MX, TI OMAP and TI DaVinci platforms, though this appears to be
a coincidence.
There are also cleanups for the Marvell Orion family and the Arm
integrator series and a Kconfig change for Broadcom"

Kernel now supports chained power-off handlers. Use
register_platform_power_off() that registers a platform level power-off
handler. Legacy pm_power_off() will be removed once all drivers and archs
are converted to the new sys-off API.

For each memory region the first 10K are reserved for DDR training. Emit
a warning if the area happens to be smaller than these 10K. This should
not happen, but if it does this message simplifies diagnosing the

The wlf-gf-module driver doesn't use the driver_data member of struct
i2c_device_id, so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

__init to clears up a section mismatch seen with the recent LLVM

After a recent LLVM change [1] that deduces __cold on functions that
only call cold code (such as __init functions), there is a section
mismatch warning from imx7d_enet_init(), which got moved to
.text.unlikely. as a result of that optimization:
WARNING: modpost: vmlinux: section mismatch in reference: imx7d_enet_init+0x20 (section: .text.unlikely.) -> imx7d_enet_clk_sel (section: .init.text)
Drop the inline keyword (which does not guarantee inlining) and replace
it with __init, as imx7d_enet_init() is only called from __init code,
which clears up the warning.

The Ethernet refclock configuration is board specific and should
not be harcoded in machine code.
Remove it to align with the imx6ul commit e87f3be1c7f8 ("ARM: mach-imx:
imx6ul: remove not optional ethernet refclock overwrite").
Clearing bits 13 and 17 of GPR1 is the POR values, so this change
does not affect existing boards in mainline.
Tested on imx6sx-udoo-neo and imx6sx-sdb boards.
