If CONFIG_DEBUG_INFO_REDUCED is enabled in the kernel configuration, we
will typically not be able to load vmlinux-gdb.py and will fail with:

Linux makes use of the Radix Tree data structure to store pointers indexed
by integer values. This structure is utilised across many structures in
the kernel including the IRQ descriptor tables, and several filesystems.
This module provides a method to lookup values from a structure given its
head node.
Usage:
The function lx_radix_tree_lookup, must be given a symbol of type struct
radix_tree_root, and an index into that tree.
The object returned is a generic integer value, and must be cast correctly
to the type based on the storage in the data structure.
For example, to print the irq descriptor in the sparse irq_desc_tree at
index 18, try the following:
(gdb) print (struct irq_desc)$lx_radix_tree_lookup(irq_desc_tree, 18)
This script previously existed under commit
e127a73d41 ("scripts/gdb: add a Radix Tree
Parser") and was later reverted with
b447e02548a3304c47b78b5e2d75a4312a8f17e1i (Revert "scripts/gdb: add a
Radix Tree Parser").
This version expects the XArray based radix tree implementation and has
been verified using QEMU/x86 on Linux 6.3-rc5.

"Link:" and "Closes:" tags have to be used with public URLs.
It is difficult to make sure the link is public but at least we can verify
the tag is followed by 'http(s)://'.
With that, we avoid such a tag that is not allowed [1]:
Closes: <number>
Now that we check the "link" tags are followed by a URL, we can relax the
check linked to "Reported-by being followed by a link tag" to only verify
if a "link" tag is present after the "Reported-by" one.

The following commit will allow the use of a similar "link" tag.
Because there is a possibility that other similar tags will be added in
the future and to reduce the number of places where the code will be
modified to allow this new tag, a list with all these "link" tags is now
used.
Two variables are created from it: one to search for such tags and one to
print all tags in a warning message.

need to print the next line if there is no next line.
While at it, also mention in this case that the "Link:" tag should be
followed by a URL, similar to the next warning.
By doing that, the code is now similar to what is done above when checking

This is inconsistent with its parsing of Module.symvers and with their

strtol() clamps values to [LONG_MIN, LONG_MAX], and when building on a
32-bit system this changes all CRCs >= 0x80000000 to be 0x7fffffff.

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().

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

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.

Since commit c5bf2efb05 ("kbuild: deb-pkg: fix binary-arch and clean
in debian/rules"), the source package generated by 'make deb-pkg' fails
to build.
I terribly missed the fact that the intdeb-pkg target may regenerate
include/config/kernel.release due to the following in the top Makefile:
%pkg: include/config/kernel.release FORCE
Restore KERNELRELEASE= option to avoid the kernel.release disagreement
between build-arch and binary-arch.

Prior to commit 5ee5465940 ("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.

My randconfig build setup ran into another kallsyms warning:
Inconsistent kallsyms data
Try make KALLSYMS_EXTRA_PASS=1 as a workaround
After adding some debugging code to kallsyms.c, I saw that the recently
added kallsyms_seqs_of_names symbol can sometimes cause the second stage
table to be slightly longer than the first stage, which makes the
build inconsistent.
Add it to the exception table that contains all other kallsyms-generated
symbols.

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 a0a12c3ed0 ("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.
Harald Arnesen pointed out ICC (classic Intel C/C++ compiler) is
deprecated:
$ icc -v
icc: remark #10441: The Intel(R) C++ Compiler Classic (ICC) is
deprecated and will be removed from product release in the second half
of 2023. The Intel(R) oneAPI DPC++/C++ Compiler (ICX) is the recommended
compiler moving forward. Please transition to use this compiler. Use
'-diag-disable=10441' to disable this message.

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.
Take KERNELRELEASE and KBUILD_BUILD_VERSION from the version field of
debian/changelog in case it is updated afterwards.

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.

Currently, perf-tar*-src-pkg only uses 'git archive', but it is better

The file, HEAD, which saves the commit hash, will be included in the

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.
