Currently, the family code and subfamily code are derived from the
PMC_TAP_IDCODE register. Versal, Versal NET share the same family
code. Also some platforms share the same subfamily code, making it
difficult to distinguish between platforms. Update
zynqmp_pm_get_family_info() to use IDs derived from the compatible
string instead of silicon ID codes derived from PMC_TAP_IDCODE register.

The family code is currently derived from the PMC_TAP_IDCODE register
value, but there are issues where Versal, Versal NET, and future
platforms share the same family code. Additionally for some platforms
have identical subfamily code, making it challenging to differentiate
between platforms based on the family and subfamily codes. To resolve
this, a new family code member is added to the platform data, initialized
with unique values. This change enables better platform distinction via
the compatible string.

Commit 620c266f39 ("fhandle: relax open_by_handle_at() permission
checks") relaxed the coditions for decoding a file handle from non init
userns.
The conditions are that that decoded dentry is accessible from the user
provided mountfd (or to fs root) and that all the ancestors along the
path have a valid id mapping in the userns.
These conditions are intentionally more strict than the condition that
the decoded dentry should be "lookable" by path from the mountfd.
For example, the path /home/amir/dir/subdir is lookable by path from
unpriv userns of user amir, because /home perms is 755, but the owner of
/home does not have a valid id mapping in unpriv userns of user amir.
The current code did not check that the decoded dentry itself has a
valid id mapping in the userns. There is no security risk in that,
because that final open still performs the needed permission checks,
but this is inconsistent with the checks performed on the ancestors,
so the behavior can be a bit confusing.
Add the check for the decoded dentry itself, so that the entire path,
including the last component has a valid id mapping in the userns.

KR260 (robotics platform) and KD240 (driver platform).
The bootflow is the same that's why for more information please take a look
at above commits.
The KD240 kit is based on smaller k24 SOM with only 2GB of memory.

The correct operating mode for the fan is inversed (1). The previous pwm
driver implementation had a bug and the polarity information was propagated
incorrectly to the kernel. The normal (0) polarity specified in the device
tree was incorrectly clearing the polarity bit in the counter control
register. After the bug fix, setting the polarity to inversed (1) in the
device tree will clear the polarity bit.
Also provide label for custom description based on this SOM.

ice: split ice_virtchnl.c git-blame friendly way
Przemek Kitszel says:
Split ice_virtchnl.c into two more files (+headers), in a way
that git-blame works better.
Then move virtchnl files into a new subdir.
No logic changes.
I have developed (or discovered ;)) how to split a file in a way that
both old and new are nice in terms of git-blame
There was not much discussion on [RFC], so I would like to propose
to go forward with this approach.
There are more commits needed to have it nice, so it forms a git-log vs
git-blame tradeoff, but (after the brief moment that this is on the top)
we spend orders of magnitude more time looking at the blame output (and
commit messages linked from that) - so I find it much better to see
actual logic changes instead of "move xx to yy" stuff (typical for
"squashed/single-commit splits").
Cherry-picks/rebases work the same with this method as with simple
"squashed/single-commit" approach (literally all commits squashed into
one (to have better git-log, but shitty git-blame output).
Rationale for the split itself is, as usual, "file is big and we want to
extend it".

s390 and x86 have required LLVM 15 since
30d17fac6a ("scripts/min-tool-version.sh: raise minimum clang version to 15.0.0 for s390")
7861640aac ("x86/build: Raise the minimum LLVM version to 15.0.0")
respectively. This series bumps the rest of the kernel to 15.0.0 to
match, which allows for a decent number of clean ups.
On the distros front, we will only leave behind Debian Bookworm and
Ubuntu Jammy. In both of those cases, builders / developers can either
use the kernel.org toolchains or https://apt.llvm.org to get newer
versions that will run on those distributions, if they cannot upgrade.

Now that the minimum supported version of LLVM for building the kernel
has been bumped to 15.0.0, two KMSAN checks can be cleaned up.
CONFIG_HAVE_KMSAN_COMPILER will always be true when using clang so
remove the cc-option test and use a simple check for CONFIG_CC_IS_CLANG.
CONFIG_HAVE_KMSAN_PARAM_RETVAL will always be true so it can be removed
outright.

7861640aac ("x86/build: Raise the minimum LLVM version to 15.0.0")
respectively but most other architectures allow LLVM 13.0.1 or newer. In
accordance with the recent minimum supported version of GCC bump that
happened in
118c40b7b5 ("kbuild: require gcc-8 and binutils-2.30")
do the same for LLVM to 15.0.0.
Of the supported releases of Arch Linux, Debian, Fedora, and OpenSUSE
surveyed in evaluating this bump, this only leaves behind Debian
Bookworm (14.0.6) and Ubuntu Jammy (14.0.0). Debian Trixie has 19.1.7
and Ubuntu Noble has 18.1.3 (so there are viable upgrade paths) or users
can use apt.llvm.org, which provides even newer packages for those
distributions.

mlx5 has a Kconfig co-dependency on VXLAN, even tho it doesn't
call any VXLAN function (unlike mlxsw). Perhaps this dates back
to very old days when tunnel ports were fetched directly from
VXLAN.
Remove the dependency to allow MLX5=y + VXLAN=m kernel configs.
But still avoid compiling in the lib/vxlan code if VXLAN=n.

The C45 accessors were setting the GR (register number) field twice,
once with the 16-bit register address truncated to five bits, and
then overwritten with the C45 devad. This is harmless since the field
was being cleared prior to being updated with the C45 devad, except
for the extra work.
Remove the redundant code.
