The canonical location for the tracefs filesystem is at /sys/kernel/tracing.
But, from Documentation/trace/ftrace.rst:
Before 4.1, all ftrace tracing control files were within the debugfs
file system, which is typically located at /sys/kernel/debug/tracing.
For backward compatibility, when mounting the debugfs file system,
the tracefs file system will be automatically mounted at:
/sys/kernel/debug/tracing
scripts/leaking_addresses.pl only skipped this older debugfs path, so
let's add the canonical path as well.

Introduce AMD CDX bus, which provides a mechanism for scanning
and probing CDX devices. These devices are memory mapped on
system bus for Application Processors(APUs).
CDX devices can be changed dynamically in the Fabric and CDX
bus interacts with CDX controller to rescan the bus and
rediscover the devices.

Mark reported that the ORC unwinder incorrectly marks an unwind as
reliable when the unwind terminates prematurely in the dark corners of
return_to_handler() due to lack of information about the next frame.
The problem is UNWIND_HINT_EMPTY is used in two different situations:
1) The end of the kernel stack unwind before hitting user entry, boot
code, or fork entry
2) A blind spot in ORC coverage where the unwinder has to bail due to
lack of information about the next frame
The ORC unwinder has no way to tell the difference between the two.
When it encounters an undefined stack state with 'end=1', it blindly
marks the stack reliable, which can break the livepatch consistency
model.
Fix it by splitting UNWIND_HINT_EMPTY into UNWIND_HINT_UNDEFINED and
UNWIND_HINT_END_OF_STACK.

modpost now reads CRCs from .*.cmd files, parsing them using strtol().
This is inconsistent with its parsing of Module.symvers and with their
definition as *unsigned* 32-bit values.
strtol() clamps values to [LONG_MIN, LONG_MAX], and when building on a
32-bit system this changes all CRCs >= 0x80000000 to be 0x7fffffff.
Change extract_crcs_for_object() to use strtoul() instead.

As a result of the switch to dh_listpackages, $version is no longer set
when install_kernel_headers() is called. This causes files in the
linux-headers deb package to be installed to a path with an empty
$version (e.g. /usr/src/linux-headers-/scripts/sign-file rather than
/usr/src/linux-headers-6.3.0-rc3/scripts/sign-file).
To avoid this, while continuing to use the version information from
dh_listpackages, pass $version from $package as the second argument
of install_kernel_headers().

Commit 5c3d1d0abb12 ("kbuild: add a tool to list files ignored by git")
added a new tool, scripts/list-gitignored. My intention was to create
source packages without cleaning the source tree, without relying on git.
Linus strongly objected to it, and suggested using 'git archive' instead.
[1] [2] [3]
This commit goes in that direction - Remove scripts/list-gitignored.c
and rewrites Makefiles and scripts to use 'git archive' for building
Debian and RPM source packages. It also makes 'make perf-tar*-src-pkg'
use 'git archive' again.
Going forward, building source packages is only possible in a git-managed
tree. Building binary packages does not require git.

Use dh_listpackages to get a list of all binary packages.
With this, debian/control lists which binary packages will be produced.
Previously, ARCH=um listed linux-libc-dev in debian/control, but it
was not generated because each of mkdebian and builddeb independently
maintained the if-conditionals.
Another motivation is to allow scripts/package/builddeb to get the
package name (linux-image-*, etc.) dynamically from debian/control.
This will also allow the BuildProfile to control the generation of
the binary packages.

KERNELRELEASE does not need to match the package version in changelog.
Rather, it conventially matches what is called 'ABINAME', which is a
part of the binary package names.
Both are the same by default, but the former might be overridden by
KDEB_PKGVERSION. In this case, the resulting package would not boot
because /lib/modules/$(uname -r) does not point the module directory.

I terribly missed the fact that the intdeb-pkg target may regenerate

%pkg: include/config/kernel.release FORCE
Restore KERNELRELEASE= option to avoid the kernel.release disagreement
between build-arch and binary-arch.

Prior to commit 5ee546594025 ("kconfig: change sym_change_count to a
boolean flag"), the conf_updated flag was set to the new value *before*
calling the callback. xconfig's save action depends on this behaviour,
because xconfig calls conf_get_changed() directly from the callback and
now sees the old value, thus never enabling the save button or the
shortcut.
Restore the previous behaviour.

include/linux/compiler-intel.h had no update in the past 3 years.
We often forget about the third C compiler to build the kernel.
For example, commit a0a12c3ed057 ("asm goto: eradicate CC_HAS_ASM_GOTO")
only mentioned GCC and Clang.
init/Kconfig defines CC_IS_GCC and CC_IS_CLANG but not CC_IS_ICC,
and nobody has reported any issue.
I guess the Intel Compiler support is broken, and nobody is caring
about it.

deprecated:

Improve the source package support in case the dpkg-buildpackage is
directly used to build binary packages.
For cross-compiling, you can set CROSS_COMPILE via the environment
variable, but it is better to set it automatically - set it to
${DEB_HOST_GNU_TYPE}- if we are cross-compiling but not from the top
Makefile.
The generated source package may be carried to a different build
environment, which may have a different compiler installed.
Run olddefconfig first to set new CONFIG options to their default
values without prompting.

The clean target needs ARCH=${ARCH} to clean up the tree for the correct
architecture. 'make (bin)deb-pkg' skips cleaning, but the preclean hook
may be executed if dpkg-buildpackage is directly used.
The binary-arch target does not need KERNELRELEASE because it is not
updated during the installation. KBUILD_BUILD_VERSION is not needed
either because binary-arch does not build vmlinux.

Change the source format from "1.0" to "3.0 (quilt)" because it works
more cleanly.
All files except .config and debian/ go into the orig tarball.
Add a single patch, debian/patches/config, and delete the ugly
extend-diff-ignore patterns.
The debian tarball will be compressed into *.debian.tar.xz by default.
If you like to use a different compression mode, you can pass the
command line option, DPKG_FLAGS=-Zgzip, for example.
The orig tarball only supports gzip for now. The combination of
gzip and xz is somewhat clumsy, but it is not a practical problem.

If you run 'make (src)rpm-pkg', all objects are lost due to 'make clean',
which makes the incremental builds impossible.
Instead of cleaning, pass the exclude list to tar's --exclude-from
option.
Previously, the .config was contained in the source tarball.
With this commit, the source rpm consists of separate linux.tar.gz
and .config.
Remove stale comments. Now, 'make (src)rpm-pkg' works with O= option.

The build rules of rpm-pkg and srcrpm-pkg are almost the same.
Remove the code duplication.
Change rpm-pkg to build binary packages from the source package generated
by srcrpm-pkg.
This changes the output directory of the srpm generated by 'make rpm-pkg'
because srcrpm-pkg overrides _srcrpmdir.

If you run 'make deb-pkg', all objects are lost due to 'make clean',
which makes the incremental builds impossible.
Instead of cleaning, pass the exclude list to tar's --exclude-from

Previously, *.diff.gz contained some check-in files such as
.clang-format, .cocciconfig.
With this commit, *.diff.gz will only contain the .config and debian/.
The other source files will go into the .orig tarball.
linux.tar.gz is rebuilt only when the source files that would go into

Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work
falls into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be
moved into read-only memory (i.e. const) The recent work with Rust
has pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only
making things safer overall. This is the contuation of that work
(started last release with kobject changes) in moving struct
bus_type to be constant. We didn't quite make it for this release,
but the remaining patches will be finished up for the release after
this one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems"

that there's a pending report that has a fix that is queued up - Linus ]

Pull modules updates from Luis Chamberlain:
"Nothing exciting at all for modules for v6.3.
The biggest change is just the change of INSTALL_MOD_DIR from "extra"
to "updates" which I found lingered for ages for no good reason while
testing the CXL mock driver [0].
The CXL mock driver has no kconfig integration and requires building
an external module... and re-building the *rest* of the production
drivers. This mock driver when loaded but not the production ones will
crash.
All this can obviously be fixed by integrating kconfig semantics into
such test module, however that's not desirable by the maintainer, and
so sensible defaults must be used to ensure a default "make
modules_install" will suffice for most distros which do not have a
file like /etc/depmod.d/dist.conf with something like `search updates
extra built-in`.
Since most distros rely on kmod and since its inception the "updates"
directory is always in the search path it makes more sense to use that
than the "extra" which only *some* RH based systems rely on.
All this stuff has been on linux-next for a while"
