Stop using struct fd to return a real file from ovl_real_fdget(),
because we no longer return a temporary file object and the callers

When an overlayfs file is opened as lower and then the file is copied up,
every operation on the overlayfs open file will open a temporary backing
file to the upper dentry and close it at the end of the operation.
Store the upper real file along side the original (lower) real file in
ovl_file instead of opening a temporary upper file on every operation.

Instead of using ->private_data to point at realfile directly, so
that we can add more context per ovl open file.

ovl_fsync() with !datasync opens a backing file from the top most dentry
in the stack, checks if this dentry is non-upper and skips the fsync.
In case of an overlay dentry stack with lower data and lower metadata
above it, but without an upper metadata above it, the backing file is
opened from the top most lower metadata dentry and never used.
Refactor the helper ovl_real_fdget_meta() into ovl_real_fdget_path() and
open code the checks for non-upper inode in ovl_fsync(), so in that case
we can avoid the unneeded backing file open.

Use override_creds_light() in ovl_override_creds() and
revert_creds_light() in ovl_revert_creds().
The _light() functions do not change the 'usage' of the credentials in
question, as they refer to the credentials associated with the
mounter, which have a longer lifetime.
In ovl_setup_cred_for_create(), do not need to modify the mounter
credentials (returned by override_creds_light()) 'usage' counter.
Add a warning to verify that we are indeed working with the mounter
credentials (stored in the superblock). Failure in this assumption
means that creds may leak.

ovl_setup_cred_for_create() decrements one refcount of new creds and
ovl_revert_creds() in callers decrements the last refcount.
In preparation to revert_creds_light() back to caller creds, pass an
explicit reference of the creators creds to the callers and drop the
refcount explicitly in the callers after ovl_revert_creds().

dentry_open in ovl_security_fileattr fails for any file
larger than 2GB if open method of the underlying filesystem
calls generic_file_open (e.g. fusefs).
The issue can be reproduce using the following script:
(passthrough_ll is an example app from libfuse).
$ D=/opt/test/mnt
$ mkdir -p ${D}/{source,base,top/uppr,top/work,ovlfs}
$ dd if=/dev/zero of=${D}/source/zero.bin bs=1G count=2
$ passthrough_ll -o source=${D}/source ${D}/base
$ mount -t overlay overlay \
-olowerdir=${D}/base,upperdir=${D}/top/uppr,workdir=${D}/top/work \
${D}/ovlfs
$ chmod 0777 ${D}/mnt/ovlfs/zero.bin
Running this script results in "Value too large for defined data type"
error message from chmod.

If the caller supplies an iocb->ki_pos value that is close to the
filesystem upper limit, and an iterator with a count that causes us to
overflow that limit, then filemap_read() enters an infinite loop.
This behaviour was discovered when testing xfstests generic/525 with the
"localio" optimisation for loopback NFS mounts.

Pull thermal control fixes from Rafael Wysocki:
"These fix one issue in the qcom lmh thermal driver, a DT handling
issue in the thermal core and two issues in the userspace thermal
library:
- Allow tripless thermal zones defined in a DT to be registered in
accordance with the thermal DT bindings (Icenowy Zheng)
- Annotate LMH IRQs with lockdep classes to prevent lockdep from
reporting a possible recursive locking issue that cannot really
occur (Dmitry Baryshkov)
- Improve the thermal library "make clean" to remove a leftover
symbolic link created during compilation and fix the sampling
handler invocation in that library to pass the correct pointer to
it (Emil Dahl Juhl, zhang jiao)"

When the Tx FIFO is empty and the last command has no STOP bit
set, the master holds SCL low. If I2C_DYNAMIC_TAR_UPDATE is not
set, BIT(13) MST_ON_HOLD of IC_RAW_INTR_STAT is not enabled,
causing the __i2c_dw_disable() timeout. This is quite similar to
commit 2409205acd ("i2c: designware: fix __i2c_dw_disable() in
case master is holding SCL low"). Also check BIT(7)
MST_HOLD_TX_FIFO_EMPTY in IC_STATUS, which is available when
IC_STAT_FOR_CLK_STRETCH is set.

Some trivial syzbot fixes, two more serious btree fixes found by looping
single_devices.ktest small_nodes:
- Topology error on split after merge, where we accidentaly picked the
node being deleted for the pivot, resulting in an assertion pop
- New nodes being preallocated were left on the freedlist, unlocked,
resulting in them sometimes being accidentally freed: this dated from
pre-cycle detector, when we could leave them locked. This should have
resulted in more explosions and fireworks, but turned out to be
surprisingly hard to hit because the preallocated nodes were being
used right away.
the fix for this is bigger than we'd like - reworking btree list
handling was a bit invasive - but we've now got more assertions and
it's well tested.
- Also another mishandled transaction restart fix (in
btree_node_prefetch) - we're almost done with those.

"Here is a (hopefully) final round of arm64 fixes for 6.12 that address
some user-visible floating point register corruption. Both of the
Marks have been working on this for a couple of weeks and we've ended
up in a position where SVE is solid but SME still has enough pending
issues that the most pragmatic solution for the release and stable
backports is to disable the feature. Yes, it's a shame, but the
hardware is rare as hen's teeth at the moment and we're better off
getting back to a known good state before fixing it all properly.
We're also improving the selftests for 6.13 to help avoid merging
broken code in the future.
Anyway, the good news is that we're removing a lot more code than
we're adding.
Summary:
- Fix handling of SVE traps from userspace on preemptible kernels

Prior to commit d646969055 ("Reimplement RLIMIT_SIGPENDING on top of
ucounts") UCOUNT_RLIMIT_SIGPENDING rlimit was not enforced for a class of
signals. However now it's enforced unconditionally, even if
override_rlimit is set. This behavior change caused production issues.
For example, if the limit is reached and a process receives a SIGSEGV
signal, sigqueue_alloc fails to allocate the necessary resources for the
signal delivery, preventing the signal from being delivered with siginfo.
This prevents the process from correctly identifying the fault address and
handling the error. From the user-space perspective, applications are
unaware that the limit has been reached and that the siginfo is
effectively 'corrupted'. This can lead to unpredictable behavior and
crashes, as we observed with java applications.
Fix this by passing override_rlimit into inc_rlimit_get_ucounts() and skip
the comparison to max there if override_rlimit is set. This effectively
restores the old behavior.
