Subject: [PATCH v1 0/2] scripts: introduce containerized builds

This proposal emerged from an email discussion and a talk at Plumbers
last year:

    https://lore.kernel.org/all/affb7aff-dc9b-4263-bbd4-a7965c19ac4e@gtucker.io/

The aim is to facilitate reproducing builds for CI bots as well as
developers using containers.  Here's an illustrative example with a
kernel.org toolchain in a Docker image from tuxmake:

    $ scripts/container -i tuxmake/korg-clang-21 make LLVM=1 defconfig
      HOSTCC  scripts/basic/fixdep
      HOSTCC  scripts/kconfig/conf.o
    [...]
      HOSTCC  scripts/kconfig/util.o
      HOSTLD  scripts/kconfig/conf
    *** Default configuration is based on 'x86_64_defconfig'
    #
    # configuration written to .config
    #

and a follow-up command to build the kernel with the verbose flag
turned on to show DEBUG log messages from the container tool:

    $ scripts/container -i tuxmake/korg-clang-21 -v -- make LLVM=1 -j8
    [container DEBUG] runtime=docker, image=tuxmake/korg-clang-21
      GEN     arch/x86/include/generated/asm/orc_hash.h
      HOSTCC  scripts/basic/fixdep
      SYSHDR  arch/x86/include/generated/uapi/asm/unistd_32.h
      SYSHDR  arch/x86/include/generated/uapi/asm/unistd_64.h
      SYSHDR  arch/x86/include/generated/uapi/asm/unistd_x32.h
      WRAP    arch/x86/include/generated/uapi/asm/bpf_perf_event.h
      WRAP    arch/x86/include/generated/uapi/asm/errno.h
    [...]
      LD      arch/x86/boot/setup.elf
      OBJCOPY arch/x86/boot/setup.bin
      BUILD   arch/x86/boot/bzImage
    Kernel: arch/x86/boot/bzImage is ready  (#1)

While the example above uses a tuxmake image, I've also started
preparing reference container images with kernel.org toolchains and
no third-party dependencies other than the base Debian distro:

    https://gitlab.com/gtucker/korg-containers

This patch series include a documentation page with all the relevant
details about how to use the tool and images currently available.
