Since the GPIO interrupt controller is always not working properly, we need
to constantly add workaround to cope with hardware deficiencies. So just
remove GPIO interrupt controller, and let the SFP driver poll the GPIO
status.

====================
eth: fbnic: cleanup and add a few stats
Cleanup trival problems with fbnic and add the PCIe and RPC (Rx parser)
stats.
All stats are read under rtnl_lock for now, so the code is pretty
trivial. We'll need to add more locking when we start gathering
drops used by .ndo_get_stats64.

Report Rx parser statistics via ethtool -S.
The parser stats are 32b, so we need to add refresh to the service
task to make sure we don't miss overflows.

Add PCIe hardware statistics support to the fbnic driver. These stats
provide insight into PCIe transaction performance and error conditions.
Which includes, read/write and completion TLP counts and DWORD counts and
debug counters for tag, completion credit and NP credit exhaustion
The stats are exposed via debugfs and can be used to monitor PCIe
performance and debug PCIe issues.

This patch only adds the directories, subsequent changes

Commit 51183d233b ("net/neighbor: Update neigh_dump_info for strict
data checking") added strict checking. The err variable is not cleared,
so if we find no table to dump we will return the validation error even
if user did not want strict checking.
I think the only way to hit this is to send an buggy request, and ask
for a table which doesn't exist, so there's no point treating this
as a real fix. I only noticed it because a syzbot repro depended on it
to trigger another bug.

Because optimizing the power consumption of t7XX,
change auto suspend time to 5000.
The Tests uses a script to loop through the power_state
of t7XX.
(for example: /sys/bus/pci/devices/0000\:72\:00.0/power_state)
* If Auto suspend is 20 seconds,
test script show power_state have 0~5% of the time was in D3 state
when host don't have data packet transmission.
* Changed auto suspend time to 5 seconds,
test script show power_state have 50%~80% of the time was in D3 state
when host don't have data packet transmission.
We tested Fibocom FM350 and our products using the t7xx and they all
benefited from this.

Binder places its headers under include/uapi/linux/android/

Pull selinux updates from Paul Moore:
- Add support for netlink xperms
Some time ago we added the concept of "xperms" to the SELinux policy
so that we could write policy for individual ioctls, this builds upon
this by using extending xperms to netlink so that we can write
SELinux policy for individual netlnk message types and not rely on
the fairly coarse read/write mapping tables we currently have.
There are limitations involving generic netlink due to the
multiplexing that is done, but it's no worse that what we currently
have. As usual, more information can be found in the commit message.
- Deprecate /sys/fs/selinux/user
We removed the only known userspace use of this back in 2020 and now
that several years have elapsed we're starting down the path of
deprecating it in the kernel.
- Cleanup the build under scripts/selinux
A couple of patches to move the genheaders tool under
security/selinux and correct our usage of kernel headers in the tools
located under scripts/selinux. While these changes originated out of
an effort to build Linux on different systems, they are arguably the
right thing to do regardless.
- Minor code cleanups and style fixes
Not much to say here, two minor cleanup patches that came out of the
netlink xperms work

Merge tag 'for-6.13/io_uring-20241118' of git://git.kernel.dk/linux
Pull io_uring updates from Jens Axboe:
- Cleanups of the eventfd handling code, making it fully private.
- Support for sending a sync message to another ring, without having a
ring available to send a normal async message.
- Get rid of the separate unlocked hash table, unify everything around
the single locked one.
- Add support for ring resizing. It can be hard to appropriately size
the CQ ring upfront, if the application doesn't know how busy it will
be. This results in applications sizing rings for the most busy case,
which can be wasteful. With ring resizing, they can start small and
grow the ring, if needed.
- Add support for fixed wait regions, rather than needing to copy the
same wait data tons of times for each wait operation.
- Rewrite the resource node handling, which before was serialized per
ring. This caused issues with particularly fixed files, where one
file waiting on IO could hold up putting and freeing of other
unrelated files. Now each node is handled separately. New code is
much simpler too, and was a net 250 line reduction in code.
- Add support for just doing partial buffer clones, rather than always
cloning the entire buffer table.
- Series adding static NAPI support, where a specific NAPI instance is
used rather than having a list of them available that need lookup.
- Add support for mapped regions, and also convert the fixed wait
support mentioned above to that concept. This avoids doing special
mappings for various planned features, and folds the existing
registered wait into that too.
- Add support for hybrid IO polling, which is a variant of strict
IOPOLL but with an initial sleep delay to avoid spinning too early
and wasting resources on devices that aren't necessarily in the < 5
usec category wrt latencies.
- Various cleanups and little fixes.

Pull btrfs updates from David Sterba:
"Changes outside of btrfs: add io_uring command flag to track a dying
task (the rest will go via the block git tree).
User visible changes:
- wire encoded read (ioctl) to io_uring commands, this can be used on
itself, in the future this will allow 'send' to be asynchronous. As
a consequence, the encoded read ioctl can also work in non-blocking
mode
- new ioctl to wait for cleaned subvolumes, no need to use the
generic and root-only SEARCH_TREE ioctl, will be used by "btrfs
subvol sync"
- recognize different paths/symlinks for the same devices and don't
report them during rescanning, this can be observed with LVM or DM
- seeding device use case change, the sprout device (the one
capturing new writes) will not clear the read-only status of the
super block; this prevents accumulating space from deleted
snapshots
Performance improvements:
- reduce lock contention when traversing extent buffers
- reduce extent tree lock contention when searching for inline
backref
- switch from rb-trees to xarray for delayed ref tracking,
improvements due to better cache locality, branching factors and
more compact data structures
- enable extent map shrinker again (prevent memory exhaustion under
some types of IO load), reworked to run in a single worker thread
(there used to be problems causing long stalls under memory
pressure)
Core changes:
- raid-stripe-tree feature updates:
- make device replace and scrub work
- implement partial deletion of stripe extents
- new selftests
- split the config option BTRFS_DEBUG and add EXPERIMENTAL for
features that are experimental or with known problems so we don't
misuse debugging config for that
- subpage mode updates (sector < page):
- update compression implementations
- update writepage, writeback
- continued folio API conversions:
- buffered writes
- make buffered write copy one page at a time, preparatory work for
future integration with large folios, may cause performance drop
- proper locking of root item regarding starting send
- error handling improvements
- code cleanups and refactoring:
- dead code removal
- unused parameter reduction
- lockdep assertions"

mt_set_mode() accepts 2 boolean switches indicating whether the device
(if it follows Windows Precision Touchpad specification) should report
hardware buttons and/or surface contacts. For a casual reader it is
completely not clear, as they look at the call site, which exact mode
is being requested.
Define report_mode enum and change mt_set_mode() to accept is as
an argument instead. This allows to write:
mt_set_modes(hdev, HID_LATENCY_NORMAL, TOUCHPAD_REPORT_ALL);
or
mt_set_modes(hdev, HID_LATENCY_HIGH, TOUCHPAD_REPORT_BUTTONS);
which makes intent much more clear.

The issue that unrelated function name is shown on stack trace like
following even though it should be trampoline code address is caused by
the creation of trampoline code in the area where .init.text section
of module was freed after module is loaded.
bash-1344 [002] ..... 43.644608: <stack trace>
=> (MODULE INIT FUNCTION)
=> vfs_write
=> ksys_write
=> do_syscall_64
=> entry_SYSCALL_64_after_hwframe
To resolve this, when function address of stack trace entry is in
trampoline, output without looking up symbol name.

This work is already supported for block devices. If a block device is
opened with O_DIRECT and the block device supports atomic write, then
FMODE_CAN_ATOMIC_WRITE is added to the file of the opened block
device.
This contains the work to expand atomic write support to filesystems,
specifically ext4 and XFS. Currently, only support for writing exactly
one filesystem block atomically is added.
Since it's now possible to have filesystem block size > page size for
XFS, it's possible to write 4K+ blocks atomically on x86"

Merge tag 'vfs-6.13.tmpfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull tmpfs case folding updates from Christian Brauner:
"This adds case-insensitive support for tmpfs.
The work contained in here adds support for case-insensitive file
names lookups in tmpfs. The main difference from other casefold
filesystems is that tmpfs has no information on disk, just on RAM, so
we can't use mkfs to create a case-insensitive tmpfs. For this
implementation, there's a mount option for casefolding. The rest of
the patchset follows a similar approach as ext4 and f2fs.
The use case for this feature is similar to the use case for ext4, to
better support compatibility layers (like Wine), particularly in
combination with sandboxing/container tools (like Flatpak).
Those containerization tools can share a subset of the host filesystem
with an application. In the container, the root directory and any
parent directories required for a shared directory are on tmpfs, with
the shared directories bind-mounted into the container's view of the
filesystem.
If the host filesystem is using case-insensitive directories, then the
application can do lookups inside those directories in a
case-insensitive way, without this needing to be implemented in
user-space. However, if the host is only sharing a subset of a
case-insensitive directory with the application, then the parent
directories of the mount point will be part of the container's root
tmpfs. When the application tries to do case-insensitive lookups of
those parent directories on a case-sensitive tmpfs, the lookup will
fail"

Merge tag 'vfs-6.13.pidfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull pidfs update from Christian Brauner:
"This adds a new ioctl to retrieve information about a pidfd.
A common pattern when using pidfds is having to get information about
the process, which currently requires /proc being mounted, resolving
the fd to a pid, and then do manual string parsing of /proc/N/status
and friends. This needs to be reimplemented over and over in all
userspace projects (e.g.: it has been reimplemented in systemd, dbus,
dbus-daemon, polkit so far), and requires additional care in checking
that the fd is still valid after having parsed the data, to avoid
races.
Having a programmatic API that can be used directly removes all these
requirements, including having /proc mounted.
As discussed at LPC24, add an ioctl with an extensible struct so that
more parameters can be added later if needed. Start with returning
pid/tgid/ppid and some creds unconditionally, and cgroupid optionally"
