In the same way as for other similar files, mark as ghost the new file
generated by depmod for configured weak dependencies for modules,
modules.weakdep, so that although it is not included in the package,

ba6c664081 kbuild: rpm-pkg: Fix C locale setup
semicolon separation in LC_ALL is wrong. Either variable needs to be
exported before as a separate commit or set as part of the commit in the

This fixes broken build on user's locale setup which makes 'date' binary
to produce invalid characters in rpm changelog (e.g. cs_CZ.UTF-8 'čec'):

c8578539de kbuild: add script and target to generate pacman package
pacman is the package manager used by Arch Linux and its derivates.
Creating native packages from the kernel tree has multiple advantages:

* The package triggers the correct hooks for initramfs generation and
  bootloader configuration
* Uninstallation is complete and also invokes the relevant hooks
* New UAPI headers can be installed without any manual bookkeeping

The PKGBUILD file is a modified version of the one used for the
downstream Arch Linux "linux" package.
Extra steps that should not be necessary for a development kernel have
been removed and an UAPI header package has been added.

It is more reasonable to do so when DEBFULLNAME is unset or null.

c520908053 kbuild: deb-pkg: remove support for "name <email>" form for DEBEMAIL
Commit d5940c60e0 ("kbuild: deb-pkg improve maintainer address
generation") supported the "name <email>" form for DEBEMAIL, with
behavior slightly different from devscripts.

In Kbuild, if DEBEMAIL is given in the form "name <email>", it is used
as-is, and DEBFULLNAME is ignored.

In contrast, debchange takes the name from DEBFULLNAME (or NAME) if set,
as described in 'man debchange':

  If this variable has the form "name <email>", then the maintainer name
  will also be taken from here if neither DEBFULLNAME nor NAME is set.

This commit removes support for the "name <email> form for DEBEMAIL,
as the current behavior is already different from debchange, and the
Debian manual suggests setting the email address and name separately in
DEBEMAIL and DEBFULLNAME. [1]

If there are any complaints about this removal, we can re-add it,
with better alignment with the debchange implementation. [2]

e3286434d2 kbuild: rpm-pkg: avoid the warnings with dtb's listed twice
After 8d1001f7bd (kbuild: rpm-pkg: fix build error with CONFIG_MODULES=n),
the following warning "warning: File listed twice: *.dtb" is appearing for
every dtb file that is included.
The reason is that the commented commit already adds the folder
/lib/modules/%{KERNELRELEASE} in kernel.list file so the folder
/lib/modules/%{KERNELRELEASE}/dtb is no longer necessary, just remove it.

To make it work irrespective of CONFIG_MODULES, this commit specifies
the directory path, /lib/modules/%{KERNELRELEASE}, instead of individual

However, doing so would cause new warnings:

Given KBUILD_IMAGE properly set in arch/*/Makefile, the default case
should work in most scenarios. The only oddity is the naming of the
copy destination, vmlinux-kbuild-${KERNELRELEASE}. Let's rename it
to vmlinuz-${KERNELRELEASE} because the kernel is often compressed.
Remove the warning to avoid unnecessary patch submissions when the
default case suffices.

Remove the x86 case, which is now equivalent to the default.

c3f7bed8fa kbuild: buildtar: add comments about inconsistent package generation
scripts/package/buildtar checks some kernel packages, and copies the
first image found. This may potentially produce an inconsistent (and
possibly wrong) package.

For instance, the for-loop for arm64 checks Image.{bz2,gz,lz4,lzma,lzo},
and vmlinuz.efi, then copies the first image found, which might be a
stale image created in a previous build.

When CONFIG_EFI_ZBOOT is enabled in the pristine source tree,
'make ARCH=arm64 tar-pkg' will build and copy vmlinuz.efi. This is the
expected behavior.

If you build the kernel with CONFIG_EFI_ZBOOT disabled, Image.gz will
be created, which will remain in the tree until you run 'make clean'.
Even if CONFIG_EFI_ZBOOT is turned on later, 'make ARCH=arm64 tar-pkg'
will copy stale Image.gz instead of the latest vmlinuz.efi, as Image.gz
takes precedence over vmlinuz.efi.

In summary, the code "[ -f ... ] && cp" does not consistently produce
the desired outcome.

Other packaging targets are deterministic; deb-pkg and rpm-pkg copies
${KBUILD_IMAGE}, which is determined by CONFIG options.

I removed [ -f ... ] checks from x86, alpha, parisc, and the default
because they have a single kernel image to copy. If it is missing, it
should be an error.

I did not modify the code for mips, arm64, riscv. Instead, I left some
comments. Eventually, someone may fix the code, or at the very least,
it may discourage the copy-pasting of incorrect code to another
architecture.

097f1200bf kbuild: rpm-pkg: add dtb files in kernel rpm
Some architectures, like aarch64 ones, need a dtb file to configure the
hardware. The default dtb file can be preloaded from u-boot, but the final
and/or more complete dtb file needs to be able to be loaded later from
rootfs.

Add the possible dtb files to the kernel rpm and mimic Fedora shipping
process, storing the dtb files in the module directory. These dtb files
will be copied to /boot directory by the install scripts, but add fallback
just in case, checking if the content in /boot directory is correct.

Mark the files installed to /boot as %ghost to make sure they will be
removed when the package is uninstalled.

Tested with Fedora Rawhide (x86_64 and aarch64) with dnf and rpm tools.
In addition, fallback was also tested after modifying the install scripts.
