The Lenovo ThinkPad X1 Fold 16 Gen 1 has an OV5675 sensor (ACPI HID
OVTI5675) behind an INT3472 discrete PMIC controller. The INT3472
_DSM returns GPIO type 0x10 for one of the pins, which controls the
DOVDD (digital I/O power) regulator enable.
Type 0x10 is not currently handled by the driver, causing the GPIO to
be ignored with a warning. Add INT3472_GPIO_TYPE_DOVDD (0x10) and
handle it as a regulator with con_id "dovdd" to match the supply name
used by sensor drivers (e.g. ov5675).
Also increase GPIO_SUPPLY_NAME_LENGTH from 5 to 6 to accommodate
the "dovdd" name (5 chars + null terminator).

Implement per-fence spinlocks, allowing implementations to not give an
external spinlock to protect the fence internal state. Instead a spinlock
embedded into the fence structure itself is used in this case.
Shared spinlocks have the problem that implementations need to guarantee
that the lock lives at least as long all fences referencing them.
Using a per-fence spinlock allows completely decoupling spinlock producer
and consumer life times, simplifying the handling in most use cases.

The fence ops of a dma_fence currently need to life as long as the
dma_fence is alive. This means that the module which originally issued
a dma_fence can't unload unless all fences are freed up.
As first step to solve this issue protect the fence ops by RCU.
While it is counter intuitive to protect a constant function pointer table
by RCU it allows modules to wait for an RCU grace period before they
unload, to make sure that nobody is executing their functions any more.
This patch has not much functional change, but only adds the RCU
handling for the static checker to test.

The primary role of pm_runtime_put() is to decrement the runtime PM
usage counter of the given device. It always does that regardless of
the value returned by it later.
In addition, if the runtime PM usage counter after decrementation turns
out to be zero, a work item is queued up to check whether or not the
device can be suspended. This is not guaranteed to succeed though and
even if it is successful, the device may still not be suspended going
forward.
There are multiple valid reasons why pm_runtime_put() may not decide to
queue up the work item mentioned above, including, but not limited to,
the case when user space has written "on" to the device's runtime PM
"control" file in sysfs. In all of those cases, pm_runtime_put()
returns a negative error code (even though the device's runtime PM
usage counter has been successfully decremented by it) which is very
confusing. In fact, its return value should only be used for debug
purposes and care should be taken when doing it even in that case.
Accordingly, to avoid the confusion mentioned above, change the return
type of pm_runtime_put() to void.

Move claimed and retune control flags out of the bitfield word to
avoid unrelated RMW side effects in asynchronous contexts.
The host->claimed bit shared a word with retune flags. Writes to claimed
in __mmc_claim_host() or retune_now in mmc_mq_queue_rq() can overwrite
other bits when concurrent updates happen in other contexts, triggering
spurious WARN_ON(!host->claimed). Convert claimed, can_retune,
retune_now and retune_paused to bool to remove shared-word coupling.

Adapt tmpfs/shmem to use the rhashtable-based xattr path and switch
from an embedded struct to pointer-based lazy allocation.
Change shmem_inode_info.xattrs from embedded 'struct simple_xattrs' to
a pointer 'struct simple_xattrs *', initialized to NULL. This avoids
the rhashtable overhead for every tmpfs inode, which helps when a lot of
inodes exist.
The xattr store is allocated on first use:
- shmem_initxattrs(): Allocates via simple_xattrs_alloc() when
security modules set initial xattrs during inode creation.
- shmem_xattr_handler_set(): Allocates on first setxattr, with a
short-circuit for removal when no xattrs are stored yet.
All read paths (shmem_xattr_handler_get, shmem_listxattr) check for
NULL xattrs pointer and return -ENODATA or 0 respectively.
Replaced xattr entries are freed via simple_xattr_free_rcu() to allow
concurrent RCU readers to finish.
shmem_evict_inode() conditionally frees the xattr store only when
allocated.
Also change simple_xattr_add() from void to int to propagate
rhashtable insertion failures. shmem_initxattrs() is the only caller.

Add rhashtable support to the simple_xattr subsystem while keeping the
existing rbtree code fully functional. This allows consumers to be
migrated one at a time without breaking any intermediate build.
struct simple_xattrs gains a dispatch flag and a union holding either
the rbtree (rb_root + rwlock) or rhashtable state:
struct simple_xattrs {
bool use_rhashtable;
union {
struct { struct rb_root rb_root; rwlock_t lock; };
struct rhashtable ht;
};
};
simple_xattrs_init() continues to set up the rbtree path for existing
embedded-struct callers.
Add simple_xattrs_alloc() which dynamically allocates a simple_xattrs
and initializes the rhashtable path. This is the entry point for
consumers switching to pointer-based lazy allocation.
The five core functions (get, set, list, add, free) dispatch based on
the use_rhashtable flag.
Existing callers continue to use the rbtree path unchanged. As each
consumer is converted it will switch to simple_xattrs_alloc() and the
rhashtable path. Once all consumers are converted a follow-up patch
will remove the rbtree code.

In preparation for converting simple_xattrs from rbtree to rhashtable,
add rhash_head and rcu_head members to struct simple_xattr. The
rhashtable implementation will use rhash_head for hash table linkage
and RCU-based lockless reads, requiring that replaced or removed xattr
entries be freed via call_rcu() rather than immediately.
Add simple_xattr_free_rcu() which schedules RCU-deferred freeing of an
xattr entry. This will be used by callers of simple_xattr_set() once
they switch to the rhashtable-based xattr store.
No functional changes.

Kingston eMMC IY2964 and IB2932 takes a fixed ~2 seconds for each secure
erase/trim operation regardless of size - that is, a single secure
erase/trim operation of 1MB takes the same time as 1GB. With default
calculated 3.5MB max discard size, secure erase 1GB requires ~300 separate
operations taking ~10 minutes total.
Add a card quirk, MMC_QUIRK_FIXED_SECURE_ERASE_TRIM_TIME, to set maximum
secure erase size for those devices. This allows 1GB secure erase to
complete in a single operation, reducing time from 10 minutes to just 2
seconds.

Some eMMC vendors need to report manufacturing dates beyond 2025 but are
reluctant to update the EXT_CSD revision from 8 to 9. Changing the
Updating the EXT_CSD revision may involve additional testing or
qualification steps with customers. To ease this transition and avoid a
full re-qualification process, a workaround is needed. This
patch introduces a temporary quirk that re-purposes the year codes
corresponding to 2010, 2011, and 2012 to represent the years 2026, 2027,
and 2028, respectively. This solution is only valid for this three-year
period.
After 2028, vendors must update their firmware to set EXT_CSD_REV=9 to
continue reporting the correct manufacturing date in compliance with the
JEDEC standard.
The `MMC_QUIRK_BROKEN_MDT` is introduced and enabled for all Sandisk
devices to handle this behavior.

Before rseq became extensible, its original size was 32 bytes even
though the active rseq area was only 20 bytes. This had the following
impact in terms of userspace ecosystem evolution:
* The GNU libc between 2.35 and 2.39 expose a __rseq_size symbol set
to 32, even though the size of the active rseq area is really 20.
* The GNU libc 2.40 changes this __rseq_size to 20, thus making it
express the active rseq area.
* Starting from glibc 2.41, __rseq_size corresponds to the
AT_RSEQ_FEATURE_SIZE from getauxval(3).
This means that users of __rseq_size can always expect it to
correspond to the active rseq area, except for the value 32, for
which the active rseq area is 20 bytes.
Exposing a 32 bytes feature size would make life needlessly painful
for userspace. Therefore, add a reserved field at the end of the
rseq area to bump the feature size to 33 bytes. This reserved field
is expected to be replaced with whatever field will come next,
expecting that this field will be larger than 1 byte.
The effect of this change is to increase the size from 32 to 64 bytes
before we actually have fields using that memory.
Clarify the allocation size and alignment requirements in the struct
rseq uapi comment.
Change the value returned by getauxval(AT_RSEQ_ALIGN) to return the
value of the active rseq area size rounded up to next power of 2, which
guarantees that the rseq structure will always be aligned on the nearest
power of two large enough to contain it, even as it grows. Change the
alignment check in the rseq registration accordingly.
This will minimize the amount of ABI corner-cases we need to document
and require userspace to play games with. The rule stays simple when
__rseq_size != 32:
#define rseq_field_available(field) (__rseq_size >= offsetofend(struct rseq_abi, field))

objtool warns about this function being called inside of a uaccess

kernel/entry/common.o: warning: objtool: irqentry_exit+0x1dc: call to rseq_arm_slice_extension_timer() with UACCESS enabled
Interestingly, this happens with CONFIG_RSEQ_SLICE_EXTENSION disabled,
so this is an empty function, as the normal implementation is
already marked __always_inline.
I could reproduce this multiple times with gcc-11 but not with gcc-15,
so the compiler probably got better at identifying the trivial function.
Mark all the empty helpers for !RSEQ_SLICE_EXTENSION as __always_inline
for consistency, avoiding this warning.

When simple-audio-card programs sysclk for CPU and codec DAIs during
hw_params, the ordering of these calls may matter on some platforms.
Some CPU DAIs finalize or adjust the MCLK rate as part of their
set_sysclk() callback (for example by calling clk_set_rate()). If the
codec sysclk is configured before the CPU DAI applies the final MCLK
rate, the codec may configure its internal clocking based on a
non-final MCLK value.
Such situations can arise depending on the clock provider/consumer
relationship between the CPU DAI and the codec.
Introduce an explicit sysclk ordering enum in simple-card-utils and use
it to control the order of snd_soc_dai_set_sysclk() calls in the mclk-fs
handling path. The default behaviour remains unchanged (codec-first)
to avoid regressions.

Current soc-compress.c clears symmetric_rate, but it clears rate only,
not clear other symmetric_channels/sample_bits.
static int soc_compr_clean(...)
{
...
if (!snd_soc_dai_active(cpu_dai))
=> cpu_dai->symmetric_rate = 0;
if (!snd_soc_dai_active(codec_dai))
=> codec_dai->symmetric_rate = 0;
...
};
This feature was added when v3.7 kernel [1], and there was only
symmetric_rate, no symmetric_channels/sample_bits in that timing.
symmetric_channels/sample_bits were added in v3.14 [2],
but I guess it didn't notice that soc-compress.c is updating symmetric_xxx.
We are clearing symmetry_xxx by soc_pcm_set_dai_params(), but is soc-pcm.c
local function. Makes it global function and clear symmetry_xxx by it.
[1] commit 1245b7005de02 ("ASoC: add compress stream support")
[2] commit 3635bf09a89cf ("ASoC: soc-pcm: add symmetry for channels and
sample bits")

Pull runtime verifier fix from Steven Rostedt:
- Fix multiple definition of __pcpu_unique_da_mon_this
After refactoring monitors, we used static per-cpu variables with the
same names across different per-cpu monitors. This is explicitly
disallowed for modules on some architectures (alpha) or if
CONFIG_DEBUG_FORCE_WEAK_PER_CPU is enabled (e.g. Fedora's debug
kernel). Make sure all those variables have different names to avoid
compilation issues.

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.

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.

Most simple allocations use GFP_KERNEL, and with the new allocation
helpers being introduced, let's just take advantage of that to simplify
that default case.
It's a numbers game:
git grep 'alloc_obj(' |
sed 's/.*\(GFP_[_A-Z]*\).*/\1/' |
sort | uniq -c | sort -n | tail
shows that about 90% of all those new allocator instances just use that
standard GFP_KERNEL.
Those helpers are already macros, and we can easily just make it be the
default case when the gfp argument is missing.
And yes, we could do that for all the legacy interfaces too, but let's
keep it to just the new ones at least for now, since those all got
converted recently anyway, so this is not any "extra" noise outside of
that limited conversion.
And, in fact, I want to do this before doing the -rc1 release, exactly
so that we don't get extra merge conflicts.

Commit 69050f8d6d07 ("treewide: Replace kmalloc with kmalloc_obj for
non-scalar types") started using the new allocation helpers, and in the
process showed that they were completely non-working.
The overflow logic in overflows_flex_counter_type() is completely the
wrong way around, and that broke __alloc_flex() completely. By chance,
the resulting code was then such a mess that clang generated
sufficiently garbage code that objtool warned about it all. Which made
it somewhat quicker to narrow things down.
While fixing overflows_flex_counter_type() would presumably fix this
all, I'm excising the whole broken overflow logic from __alloc_flex(),
because we don't want that kind of code in basic allocation functions
anyway.
That (no longer) broken overflows_flex_counter_type() thing needs to be
inserted into the actual __set_flex_counter() logic in the unlikely case
that we ever want this at all. And made conditional.

Pull kmalloc_obj conversion from Kees Cook:
"This does the tree-wide conversion to kmalloc_obj() and friends using
coccinelle, with a subsequent small manual cleanup of whitespace
alignment that coccinelle does not handle.
This uncovered a clang bug in __builtin_counted_by_ref(), so the
conversion is preceded by disabling that for current versions of
clang. The imminent clang 22.1 release has the fix.
I've done allmodconfig build tests for x86_64, arm64, i386, and arm. I
did defconfig builds for alpha, m68k, mips, parisc, powerpc, riscv,
s390, sparc, sh, arc, csky, xtensa, hexagon, and openrisc"
