Merge 7.0 Kbuild changes into kbuild-fixes

kbuild-fixes needs to be based on 6.19 to apply some fixes for 62089b804895 ("kbuild: rpm-pkg: Generate debuginfo package manually") which landed in 6.19-rc1 but the new material of 7.0 needs fixes merged as well.

	4	+====================
	5	+Containerized Builds
	6	+====================
	7	+
	8	+The ``container`` tool can be used to run any command in the kernel source tree
	9	+from within a container. Doing so facilitates reproducing builds across
	10	+various platforms, for example when a test bot has reported an issue which
	11	+requires a specific version of a compiler or an external test suite. While
	12	+this can already be done by users who are familiar with containers, having a
	13	+dedicated tool in the kernel tree lowers the barrier to entry by solving common
	14	+problems once and for all (e.g. user id management). It also makes it easier
	15	+to share an exact command line leading to a particular result. The main use
	16	+case is likely to be kernel builds but virtually anything can be run: KUnit,
	17	+checkpatch etc. provided a suitable image is available.
	18	+
	19	+
	20	+Options
	21	+=======
	22	+
	23	+Command line syntax::
	24	+
	25	+ scripts/container -i IMAGE [OPTION]... CMD...
	26	+
	27	+Available options:
	28	+
	29	+``-e, --env-file ENV_FILE``
	30	+
	31	+ Path to an environment file to load in the container.
	32	+
	33	+``-g, --gid GID``
	34	+
	35	+ Group id to use inside the container.
	36	+
	37	+``-i, --image IMAGE``
	38	+
	39	+ Container image name (required).
	40	+
	41	+``-r, --runtime RUNTIME``
	42	+
	43	+ Container runtime name. Supported runtimes: ``docker``, ``podman``.
	44	+
	45	+ If not specified, the first one found on the system will be used
	46	+ i.e. Podman if present, otherwise Docker.
	47	+
	48	+``-s, --shell``
	49	+
	50	+ Run the container in an interactive shell.
	51	+
	52	+``-u, --uid UID``
	53	+
	54	+ User id to use inside the container.
	55	+
	56	+ If the ``-g`` option is not specified, the user id will also be used for
	57	+ the group id.
	58	+
	59	+``-v, --verbose``
	60	+
	61	+ Enable verbose output.
	62	+
	63	+``-h, --help``
	64	+
	65	+ Show the help message and exit.
	66	+
	67	+
	68	+Usage
	69	+=====
	70	+
	71	+It's entirely up to the user to choose which image to use and the ``CMD``
	72	+arguments are passed directly as an arbitrary command line to run in the
	73	+container. The tool will take care of mounting the source tree as the current
	74	+working directory and adjust the user and group id as needed.
	75	+
	76	+The container image which would typically include a compiler toolchain is
	77	+provided by the user and selected via the ``-i`` option. The container runtime
	78	+can be selected with the ``-r`` option, which can be either ``docker`` or
	79	+``podman``. If none is specified, the first one found on the system will be
	80	+used while giving priority to Podman. Support for other runtimes may be added
	81	+later depending on their popularity among users.
	82	+
	83	+By default, commands are run non-interactively. The user can abort a running
	84	+container with SIGINT (Ctrl-C). To run commands interactively with a TTY, the
	85	+``--shell`` or ``-s`` option can be used. Signals will then be received by the
	86	+shell directly rather than the parent ``container`` process. To exit an
	87	+interactive shell, use Ctrl-D or ``exit``.
	88	+
	89	+.. note::
	90	+
	91	+ The only host requirement aside from a container runtime is Python 3.10 or
	92	+ later.
	93	+
	94	+.. note::
	95	+
	96	+ Out-of-tree builds are not fully supported yet. The ``O=`` option can
	97	+ however already be used with a relative path inside the source tree to keep
	98	+ separate build outputs. A workaround to build outside the tree is to use
	99	+ ``mount --bind``, see the examples section further down.
	100	+
	101	+
	102	+Environment Variables
	103	+=====================
	104	+
	105	+Environment variables are not propagated to the container so they have to be
	106	+either defined in the image itself or via the ``-e`` option using an
	107	+environment file. In some cases it makes more sense to have them defined in
	108	+the Containerfile used to create the image. For example, a Clang-only compiler
	109	+toolchain image may have ``LLVM=1`` defined.
	110	+
	111	+The local environment file is more useful for user-specific variables added
	112	+during development. It is passed as-is to the container runtime so its format
	113	+may vary. Typically, it will look like the output of ``env``. For example::
	114	+
	115	+ INSTALL_MOD_STRIP=1
	116	+ SOME_RANDOM_TEXT=One upon a time
	117	+
	118	+Please also note that ``make`` options can still be passed on the command line,
	119	+so while this can't be done since the first argument needs to be the
	120	+executable::
	121	+
	122	+ scripts/container -i docker.io/tuxmake/korg-clang LLVM=1 make # won't work
	123	+
	124	+this will work::
	125	+
	126	+ scripts/container -i docker.io/tuxmake/korg-clang make LLVM=1
	127	+
	128	+
	129	+User IDs
	130	+========
	131	+
	132	+This is an area where the behaviour will vary slightly depending on the
	133	+container runtime. The goal is to run commands as the user invoking the tool.
	134	+With Podman, a namespace is created to map the current user id to a different
	135	+one in the container (1000 by default). With Docker, while this is also
	136	+possible with recent versions it requires a special feature to be enabled in
	137	+the daemon so it's not used here for simplicity. Instead, the container is run
	138	+with the current user id directly. In both cases, this will provide the same
	139	+file permissions for the kernel source tree mounted as a volume. The only
	140	+difference is that when using Docker without a namespace, the user id may not
	141	+be the same as the default one set in the image.
	142	+
	143	+Say, we're using an image which sets up a default user with id 1000 and the
	144	+current user calling the ``container`` tool has id 1234. The kernel source
	145	+tree was checked out by this same user so the files belong to user 1234. With
	146	+Podman, the container will be running as user id 1000 with a mapping to id 1234
	147	+so that the files from the mounted volume appear to belong to id 1000 inside
	148	+the container. With Docker and no namespace, the container will be running
	149	+with user id 1234 which can access the files in the volume but not in the user
	150	+1000 home directory. This shouldn't be an issue when running commands only in
	151	+the kernel tree but it is worth highlighting here as it might matter for
	152	+special corner cases.
	153	+
	154	+.. note::
	155	+
	156	+ Podman's `Docker compatibility
	157	+ <https://podman-desktop.io/docs/migrating-from-docker/managing-docker-compatibility>`__
	158	+ mode to run ``docker`` commands on top of a Podman backend is more complex
	159	+ and not fully supported yet. As such, Podman will take priority if both
	160	+ runtimes are available on the system.
	161	+
	162	+
	163	+Examples
	164	+========
	165	+
	166	+The TuxMake project provides a variety of prebuilt container images available
	167	+on `Docker Hub <https://hub.docker.com/u/tuxmake>`__. Here's the shortest
	168	+example to build a kernel using a TuxMake Clang image::
	169	+
	170	+ scripts/container -i docker.io/tuxmake/korg-clang -- make LLVM=1 defconfig
	171	+ scripts/container -i docker.io/tuxmake/korg-clang -- make LLVM=1 -j$(nproc)
	172	+
	173	+.. note::
	174	+
	175	+ When running a command with options within the container, it should be
	176	+ separated with a double dash ``--`` to not confuse them with the
	177	+ ``container`` tool options. Plain commands with no options don't strictly
	178	+ require the double dashes e.g.::
	179	+
	180	+ scripts/container -i docker.io/tuxmake/korg-clang make mrproper
	181	+
	182	+To run ``checkpatch.pl`` in a ``patches`` directory with a generic Perl image::
	183	+
	184	+ scripts/container -i perl:slim-trixie scripts/checkpatch.pl patches/*
	185	+
	186	+As an alternative to the TuxMake images, the examples below refer to
	187	+``kernel.org`` images which are based on the `kernel.org compiler toolchains
	188	+<https://mirrors.edge.kernel.org/pub/tools/>`__. These aren't (yet) officially
	189	+available in any public registry but users can build their own locally instead
	190	+using this `experimental repository
	191	+<https://gitlab.com/gtucker/korg-containers>`__ by running ``make
	192	+PREFIX=kernel.org/``.
	193	+
	194	+To build just ``bzImage`` using Clang::
	195	+
	196	+ scripts/container -i kernel.org/clang -- make bzImage -j$(nproc)
	197	+
	198	+Same with GCC 15 as a particular version tag::
	199	+
	200	+ scripts/container -i kernel.org/gcc:15 -- make bzImage -j$(nproc)
	201	+
	202	+For an out-of-tree build, a trick is to bind-mount the destination directory to
	203	+a relative path inside the source tree::
	204	+
	205	+ mkdir -p $HOME/tmp/my-kernel-build
	206	+ mkdir -p build
	207	+ sudo mount --bind $HOME/tmp/my-kernel-build build
	208	+ scripts/container -i kernel.org/gcc -- make mrproper
	209	+ scripts/container -i kernel.org/gcc -- make O=build defconfig
	210	+ scripts/container -i kernel.org/gcc -- make O=build -j$(nproc)
	211	+
	212	+To run KUnit in an interactive shell and get the full output::
	213	+
	214	+ scripts/container -s -i kernel.org/gcc:kunit -- \
	215	+ tools/testing/kunit/kunit.py \
	216	+ run \
	217	+ --arch=x86_64 \
	218	+ --cross_compile=x86_64-linux-
	219	+
	220	+To just start an interactive shell::
	221	+
	222	+ scripts/container -si kernel.org/gcc bash
	223	+
	224	+To build the HTML documentation, which requires the ``kdocs`` image built with
	225	+``make PREFIX=kernel.org/ extra`` as it's not a compiler toolchain::
	226	+
	227	+ scripts/container -i kernel.org/kdocs make htmldocs
