Add open_tree_attr() which allow to atomically create a detached mount
tree and set mount options on it. If OPEN_TREE_CLONE is used this will
allow the creation of a detached mount with a new set of mount options
without it ever being exposed to userspace without that set of mount
options applied.

Usually interrupts are overwritten in the board file to specify a
mux-dependent dedicated wakeup irq, so there is interrupts and
interrupts-extended property which is not allowed. That has generated a
lot of noise during dts changes if just a phandle involved has randomly
changed.
Avoid that mess by specifying interrupts-extended in the dtsi file.

If CONFIG_HIGHMEM=y, two reserved blocks are allocated on R-Car Gen2:
cma: Reserved 256 MiB at 0x70000000 on node -1
cma: Reserved 64 MiB at 0x6c000000 on node -1
The first block is reserved by the family-specific rcar_gen2_reserve(),
the second by the common arm_memblock_init() (shmobile_defconfig sets
CONFIG_CMA_SIZE_MBYTES=64). As both blocks are reserved (eventually)
using dma_contiguous_reserve_area(), they both have the same name
("reserved"). Hence if CONFIG_CMA_SYSFS=y:
sysfs: cannot create duplicate filename '/kernel/mm/cma/reserved'
...
cma_sysfs_init from do_one_initcall+0x84/0x178
...
kobject: kobject_add_internal failed for reserved with -EEXIST, don't try to register things with the same name in the same directory.
This causes cma_sysfs_init() to fail completely, and not to create
/sys/kernel/mm/cma/ at all.
Fix this by dropping the R-Car Gen2-specific reservation. Compared to
when it was introduced, now there exist more flexible mechanisms to
control the size of memory reserved for CMA. Users can reserve more
memory by increasing CONFIG_CMA_SIZE_MBYTES, passing the cma=<N> kernel
command line parameter, or adding a reserved-memory/linux,cma node to
DT.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core and debugfs updates from Greg KH:
"Here is the big set of driver core and debugfs updates for 6.14-rc1.
Included in here is a bunch of driver core, PCI, OF, and platform rust
bindings (all acked by the different subsystem maintainers), hence the
merge conflict with the rust tree, and some driver core api updates to
mark things as const, which will also require some fixups due to new
stuff coming in through other trees in this merge window.
There are also a bunch of debugfs updates from Al, and there is at
least one user that does have a regression with these, but Al is
working on tracking down the fix for it. In my use (and everyone
else's linux-next use), it does not seem like a big issue at the
moment.
Here's a short list of the things in here:
- driver core rust bindings for PCI, platform, OF, and some i/o
functions.
We are almost at the "write a real driver in rust" stage now,
depending on what you want to do.
- misc device rust bindings and a sample driver to show how to use
them
- debugfs cleanups in the fs as well as the users of the fs api for
places where drivers got it wrong or were unnecessarily doing
things in complex ways.
- driver core const work, making more of the api take const * for
different parameters to make the rust bindings easier overall.
- other small fixes and updates
All of these have been in linux-next with all of the aforementioned
merge conflicts, and the one debugfs issue, which looks to be resolved
"soon""

Add the const qualifier to all the ctl_tables in the tree except for
watchdog_hardlockup_sysctl, memory_allocation_profiling_sysctls,
loadpin_sysctl_table and the ones calling register_net_sysctl (./net,
drivers/inifiniband dirs). These are special cases as they use a
registration function with a non-const qualified ctl_table argument or
modify the arrays before passing them on to the registration function.
Constifying ctl_table structs will prevent the modification of
proc_handler function pointers as the arrays would reside in .rodata.
This is made possible after commit 78eb4ea25cd5 ("sysctl: treewide:
constify the ctl_table argument of proc_handlers") constified all the
proc_handlers.

Before SLUB initialization, various subsystems used memblock_alloc to
allocate memory. In most cases, when memory allocation fails, an
immediate panic is required. To simplify this behavior and reduce
repetitive checks, introduce `memblock_alloc_or_panic`. This function
ensures that memory allocation failures result in a panic automatically,
improving code readability and consistency across subsystems that require
this behavior.

We already have a generic implementation of alloc/free up to P4D level, as
well as pgd_free(). Let's finish the work and add a generic PGD-level
alloc helper as well.
Unlike at lower levels, almost all architectures need some specific magic
at PGD level (typically initialising PGD entries), so introducing a
generic pgd_alloc() isn't worth it. Instead we introduce two new helpers,
__pgd_alloc() and __pgd_free(), and make use of them in the arch-specific
pgd_alloc() and pgd_free() wherever possible. To accommodate as many arch
as possible, __pgd_alloc() takes a page allocation order.
Because pagetable_alloc() allocates zeroed pages, explicit zeroing in
pgd_alloc() becomes redundant and we can get rid of it. Some trivial
implementations of pgd_free() also become unnecessary once __pgd_alloc()
is used; remove them.
Another small improvement is consistent accounting of PGD pages by using
GFP_PGTABLE_{USER,KERNEL} as appropriate.
Not all PGD allocations can be handled by the generic helpers. In
particular, multiple architectures allocate PGDs from a kmem_cache, and
those PGDs may not be page-sized.

Generic implementations of __pgd_alloc and __pgd_free are about to be
introduced. Rename the macros in arch/arm/mm/pgd.c to avoid clashes.
While we're at it, also pass down the mm as argument to those helpers, as
it will be needed to call the generic __pgd_{alloc,free}.

For the generic tlb_remove_table(), it is implemented in the following two
forms:
1) CONFIG_MMU_GATHER_TABLE_FREE is enabled
tlb_remove_table
--> generic __tlb_remove_table()
2) CONFIG_MMU_GATHER_TABLE_FREE is disabled
tlb_remove_table
--> tlb_remove_page
For case 1), the pagetable_dtor() has already been moved to generic
__tlb_remove_table().
For case 2), now only arm will call tlb_remove_table()/tlb_remove_ptdesc()
when CONFIG_MMU_GATHER_TABLE_FREE is disabled. Let's move
pagetable_dtor() completely to generic tlb_remove_table(), so that the
architectures can follow more easily.

Several architectures (arm, arm64, riscv and x86) define exactly the same
__tlb_remove_table(), just introduce generic __tlb_remove_table() to
eliminate these duplications.
The s390 __tlb_remove_table() is nearly the same, so also make s390
__tlb_remove_table() version generic.

Move pagetable_dtor() to __tlb_remove_table(), so that ptlock and page
table pages can be freed together (regardless of whether RCU is used).
This prevents the use-after-free problem where the ptlock is freed
immediately but the page table pages is freed later via RCU.
Page tables shouldn't have swap cache, so use pagetable_free() instead of
free_page_and_swap_cache() to free page table pages.

The pagetable_p*_dtor() are exactly the same except for the handling of
ptlock. If we make ptlock_free() handle the case where ptdesc->ptl is
NULL and remove VM_BUG_ON_PAGE() from pmd_ptlock_free(), we can unify
pagetable_p*_dtor() into one function. Let's introduce pagetable_dtor()
to do this.
Later, pagetable_dtor() will be moved to tlb_remove_ptdesc(), so that
ptlock and page table pages can be freed together (regardless of whether
RCU is used). This prevents the use-after-free problem where the ptlock
is freed immediately but the page table pages is freed later via RCU.

Pull SoC devicetree updates from Arnd Bergmann:
"We see the addition of eleven new SoCs, including a total of sixx
arm64 chips from Qualcomm alone. Overall, the Qualcomm platforms once
again make up the majority of all changes, after a couple of quieter
releases.
The new SoCs in this branch are:
- Microchip sama7d65 is a new 32-bit embedded chip with a single
Cortex-A7 and the current high end of the old Atmel SoC line.
- Samsung Exynos 9810 is a mobile phone chip used in some older
phones like the Samsung Galaxy S9
- Renesas R-Car V4H ES3.0 (R8A779G3) is an updated version of the V4H
(R8A779G0) low-power automotive SoC
- Renesas RZ/G3E (R0A09G047) is a family of embedded chips using
Cortex-A55 cores
- Qualcomm Snapdragon 8 Elite (SM8750) is a new phone chip based on
Qualcomm's Oryon CPU cores.
- Qualcomm Snapdragon AR2 (SAR2130P) is a SoC for augmented reality
glasses.
- Qualcomm IQ6 (QCS610) and IQ8 (QCS8300) are two industrial IOT
platforms.
- Snapdragon 425 (MSM8917) is a mobile phone SoC from 2016
- Qualcomm IPQ5424 is a Wi-Fi 7 networking chip
All of the above are part of already supported SoC families that only
need new devicetree files. Two additional SoCs in new families are
part of a separate branch.
There are 48 new machines in total, including six arm32 ones based on
aspeed. broadcom, microchip and st SoCs all using Cortex-A7 cores, and
a single risc-v board, the Banana Pi R3.
The remaining ones use arm64 chips from Broadcom, Samsung, NXP,
Mediatek, Qualcomm, Renesas and Rockchips and cover development
boards, phones, laptops, industrial machines routers.

Pull CRC updates from Eric Biggers:
- Reorganize the architecture-optimized CRC32 and CRC-T10DIF code to be
directly accessible via the library API, instead of requiring the
crypto API. This is much simpler and more efficient.
- Convert some users such as ext4 to use the CRC32 library API instead
of the crypto API. More conversions like this will come later.
- Add a KUnit test that tests and benchmarks multiple CRC variants.
Remove older, less-comprehensive tests that are made redundant by
this.
- Add an entry to MAINTAINERS for the kernel's CRC library code. I'm
volunteering to maintain it. I have additional cleanups and
optimizations planned for future cycles.

Pull kthread updates from Frederic Weisbecker:
"Kthreads affinity follow either of 4 existing different patterns:
1) Per-CPU kthreads must stay affine to a single CPU and never
execute relevant code on any other CPU. This is currently handled
by smpboot code which takes care of CPU-hotplug operations.
Affinity here is a correctness constraint.
2) Some kthreads _have_ to be affine to a specific set of CPUs and
can't run anywhere else. The affinity is set through
kthread_bind_mask() and the subsystem takes care by itself to
handle CPU-hotplug operations. Affinity here is assumed to be a
correctness constraint.
3) Per-node kthreads _prefer_ to be affine to a specific NUMA node.
This is not a correctness constraint but merely a preference in
terms of memory locality. kswapd and kcompactd both fall into this
category. The affinity is set manually like for any other task and
CPU-hotplug is supposed to be handled by the relevant subsystem so
that the task is properly reaffined whenever a given CPU from the
node comes up. Also care should be taken so that the node affinity
doesn't cross isolated (nohz_full) cpumask boundaries.
4) Similar to the previous point except kthreads have a _preferred_
affinity different than a node. Both RCU boost kthreads and RCU
exp kworkers fall into this category as they refer to "RCU nodes"
from a distinctly distributed tree.
Currently the preferred affinity patterns (3 and 4) have at least 4
identified users, with more or less success when it comes to handle
CPU-hotplug operations and CPU isolation. Each of which do it in its
own ad-hoc way.
This is an infrastructure proposal to handle this with the following
API changes:
- kthread_create_on_node() automatically affines the created kthread
to its target node unless it has been set as per-cpu or bound with
kthread_bind[_mask]() before the first wake-up.
- kthread_affine_preferred() is a new function that can be called
right after kthread_create_on_node() to specify a preferred
affinity different than the specified node.
When the preferred affinity can't be applied because the possible
targets are offline or isolated (nohz_full), the kthread is affine to
the housekeeping CPUs (which means to all online CPUs most of the time
or only the non-nohz_full CPUs when nohz_full= is set).
kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been
converted, along with a few old drivers.
Summary of the changes:
- Consolidate a bunch of ad-hoc implementations of
kthread_run_on_cpu()
- Introduce task_cpu_fallback_mask() that defines the default last
resort affinity of a task to become nohz_full aware
- Add some correctness check to ensure kthread_bind() is always
called before the first kthread wake up.
- Default affine kthread to its preferred node.
- Convert kswapd / kcompactd and remove their halfway working ad-hoc
affinity implementation
- Implement kthreads preferred affinity
- Unify kthread worker and kthread API's style
- Convert RCU kthreads to the new API and remove the ad-hoc affinity
implementation"
