irq_domain_create_simple() takes fwnode as the first argument. It can be
extracted from the struct device using dev_fwnode() helper instead of
using of_node with of_fwnode_handle().
So use the dev_fwnode() helper.

__pm_runtime_put_autosuspend() was meant to be used by callers that needed
to put the Runtime PM usage_count without marking the device's last busy
timestamp. It was however seen that the Runtime PM autosuspend related
functions should include that call. Thus switch the driver to
use pm_runtime_put_autosuspend().

An SNP cache coherency vulnerability requires a cache line eviction
mitigation when validating memory after a page state change to private.
The specific mitigation is to touch the first and last byte of each 4K
page that is being validated. There is no need to perform the mitigation
when performing a page state change to shared and rescinding validation.
CPUID bit Fn8000001F_EBX[31] defines the COHERENCY_SFW_NO CPUID bit
that, when set, indicates that the software mitigation for this
vulnerability is not needed.
Implement the mitigation and invoke it when validating memory (making it
private) and the COHERENCY_SFW_NO bit is not set, indicating the SNP
guest is vulnerable.

Scott Mayhew discovered a security exploit in NFS over TLS in
tls_alert_recv() due to its assumption it can read data from
the msg iterator's kvec..
kTLS implementation splits TLS non-data record payload between
the control message buffer (which includes the type such as TLS
aler or TLS cipher change) and the rest of the payload (say TLS
alert's level/description) which goes into the msg payload buffer.
This patch proposes to rework how control messages are setup and
used by sock_recvmsg().
If no control message structure is setup, kTLS layer will read and
process TLS data record types. As soon as it encounters a TLS control
message, it would return an error. At that point, NFS can setup a
kvec backed msg buffer and read in the control message such as a
TLS alert. Msg iterator can advance the kvec pointer as a part of
the copy process thus we need to revert the iterator before calling
into the tls_alert_recv.

If we log a new inode (not persisted in a past transaction) that has 0
links and extents, then log another inode with an higher inode number, we
end up with failing to replay the log tree with -EINVAL. The steps for
this are:
1) create new file A
2) write some data to file A
3) open an fd on file A
4) unlink file A
5) fsync file A using the previously open fd
6) create file B (has higher inode number than file A)
7) fsync file B
8) power fail before current transaction commits
Now when attempting to mount the fs, the log replay will fail with
-ENOENT at replay_one_extent() when attempting to replay the first
extent of file A. The failure comes when trying to open the inode for
file A in the subvolume tree, since it doesn't exist.
Before commit 5f61b96159 ("btrfs: fix inode lookup error handling
during log replay"), the returned error was -EIO instead of -ENOENT,
since we converted any errors when attempting to read an inode during
log replay to -EIO.
The reason for this is that the log replay procedure fails to ignore
the current inode when we are at the stage LOG_WALK_REPLAY_ALL, our
current inode has 0 links and last inode we processed in the previous
stage has a non 0 link count. In other words, the issue is that at
replay_one_extent() we only update wc->ignore_cur_inode if the current
replay stage is LOG_WALK_REPLAY_INODES.
Fix this by updating wc->ignore_cur_inode whenever we find an inode item
regardless of the current replay stage. This is a simple solution and easy
to backport, but later we can do other alternatives like avoid logging
extents or inode items other than the inode item for inodes with a link
count of 0.
The problem with the wc->ignore_cur_inode logic has been around since
commit f2d72f42d5 ("Btrfs: fix warning when replaying log after fsync
of a tmpfile") but it only became frequent to hit since the more recent
commit 5e85262e54 ("btrfs: fix fsync of files with no hard links not
persisting deletion"), because we stopped skipping inodes with a link
count of 0 when logging, while before the problem would only be triggered
if trying to replay a log tree created with an older kernel which has a
logged inode with 0 links.
A test case for fstests will be submitted soon.

Commit 3c7ac40d73 ("scsi: ufs: core: Delegate the interrupt service
routine to a threaded IRQ handler") introduced a regression where the UFS
interrupt status register (IS) was not cleared in ufshcd_intr() when
operating in MCQ mode. As a result, the IS register remained uncleared.
This led to a persistent issue during UIC interrupts:
ufshcd_is_auto_hibern8_error() consistently returned true because the
UFSHCD_UIC_HIBERN8_MASK bit was set, while the active command was neither
UIC_CMD_DME_HIBER_ENTER nor UIC_CMD_DME_HIBER_EXIT. This caused
continuous auto hibern8 enter errors and device failed to boot.
To fix this, ensure that the interrupt status register is properly
cleared in the ufshcd_intr() function for both MCQ mode with ESI enabled.

reference count leaks which are caused by:

perf_mmap_close() to ignore the unmap or unmap the wrong buffer.
- Several internal issues of perf_mmap(), which can cause reference count
leaks in the perf mmap, corrupt accounting or cause leaks in perf

The main fix is to prevent VMA splits by implementing the [may_]split()

I'm stepping down as the maintainer of Kbuild/Kconfig.
It was enjoyable to refactor and improve the kernel build system,
but due to personal reasons, I believe it's difficult for me to
continue in this role any further.
I discussed this off-list with Nathan and Nicolas, and they have
kindly agreed to take over the maintenance of Kbuild with Odd Fixes.
I'm grateful to them for stepping in.
As for Kconfig, there are currently no designated reviewers, so the
maintainer position will remain vacant for now. I hope someone will
step up to take on the role.

introduced a number of options specific to GNU tar to the `tar`
invocation in `gen_kheaders.sh` script. This causes the script to fail
to work on systems where `tar` is not GNU tar. This can occur e.g.
on recent Gentoo Linux installations that support using bsdtar from
libarchive instead.
Add a `TAR` make variable to make it possible to override the tar
executable used, e.g. by specifying:

The userprogs infrastructure does not expect clang being used with GNU ld
and in that case uses /usr/bin/ld for linking, not the configured $(LD).
This fallback is problematic as it will break when cross-compiling.
Mixing clang and GNU ld is used for example when building for SPARC64,
as ld.lld is not sufficient; see Documentation/kbuild/llvm.rst.
Relax the check around --ld-path so it gets used for all linkers.

Commit 2677010e77 ("Add support to set NAPI threaded for individual
NAPI") added support to enable/disable threaded napi using netlink. This
also extended the napi config save/restore functionality to set the napi
threaded state. This breaks netdev reset for drivers that use napi
threaded at device level and also use napi config save/restore on
napi_disable/napi_enable. Basically on netdev with napi threaded enabled
at device level, a napi_enable call will get stuck trying to stop the
napi kthread. This is because the napi->config->threaded is set to
disabled when threaded is enabled at device level.
The issue can be reproduced on virtio-net device using qemu. To
reproduce the issue run following,
echo 1 > /sys/class/net/threaded
ethtool -L eth0 combined 1
Update the threaded state in napi config in netif_set_threaded and add a
new test that verifies this scenario.

A lot of test cases in the file are related to the idle and unbalanced
timers of resilient nexthop groups and these tests are reported to be
flaky on slow machines running debug kernels.
Rather than marking a lot of individual tests with xfail_on_slow(),
simply mark all the tests. Note that the test is stable on non-debug
machines and that with debug kernels we are mainly interested in the
output of various sanitizers in order to determine pass / fail.
