1240dabe8d kbuild: deb-pkg: remove the CONFIG_MODULES check in buildeb
When CONFIG_MODULES is disabled for ARCH=um, 'make (bin)deb-pkg' fails
with an error like follows:

  cp: cannot create regular file 'debian/linux-image/usr/lib/uml/modules/6.4.0-rc2+/System.map': No such file or directory

Remove the CONFIG_MODULES check completely so ${pdir}/usr/lib/uml/modules
will always be created and modules.builtin.(modinfo) will be installed
under it for ARCH=um.

4243afdb93 kbuild: builddeb: always make modules_install, to install modules.builtin*
Even for a non-modular kernel, the kernel builds modules.builtin and
modules.builtin.modinfo, with information about the built-in modules.
Tools such as initramfs-tools need these files to build a working
initramfs on some systems, such as those requiring firmware.

Now that `make modules_install` works even in non-modular kernels and
installs these files, unconditionally invoke it when building a Debian
package.

c90b3bbff2 kbuild: rpm-pkg: remove kernel-drm PROVIDES
This code was added more than 20 years ago. [1]

I checked the kernel spec files in Fedora and OpenSUSE, but did not
see 'kernel-drm'. I do not know if there exists a distro that uses it
in RPM dependency.

Remove this, and let's see if somebody complains about it.

aa7d233f45 kbuild: give up untracked files for source package builds
When the source tree is dirty and contains untracked files, package
builds may fail, for example, when a broken symlink exists, a file
path contains whitespaces, etc.

Since commit 05e96e96a3 ("kbuild: use git-archive for source package
creation"), the source tarball only contains committed files because
it is created by 'git archive'. scripts/package/gen-diff-patch tries
to address the diff from HEAD, but including untracked files by the
hand-crafted script introduces more complexity. I wrote a patch [1] to
make it work in most cases, but still wonder if this is what we should
aim for.

To simplify the code, this patch just gives up untracked files. Going
forward, it is your responsibility to do 'git add' for what you want in
the source package. The script shows a warning just in case you forgot
to do so. It should be checked only when building source packages.

3ced71d273 kbuild: deb-pkg: set version for linux-headers paths
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().

05e96e96a3 kbuild: use git-archive for source package creation
Commit 5c3d1d0abb ("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.

36862e14e3 kbuild: deb-pkg: use dh_listpackages to know enabled packages
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.

f50aa51c44 kbuild: deb-pkg: set CROSS_COMPILE only when undefined

CROSS_COMPILE=i686-linux-gnu-, where the biarch compiler 'gcc' should
work for building the i386 kernel.

Check whether CROSS_COMPILE is defined, instead of whether it is non-empty.

If you invoke debian/rules via Kbuild, CROSS_COMPILE is always defined
in the top Makefile.

7a531c21f8 kbuild: deb-pkg: do not take KERNELRELEASE from the source version
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.

Partially revert 3ab18a625c ("kbuild: deb-pkg: improve the usability

3ab18a625c kbuild: deb-pkg: improve the usability of source package
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.

c5bf2efb05 kbuild: deb-pkg: fix binary-arch and clean in debian/rules
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

Add a single patch, debian/patches/config, and delete the ugly

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.
