stable/longterm maintainers maintain the code. It's thus pretty safe to assume

+
+.. _buildhost_bis:
+
+Build kernels on a different machine
+------------------------------------
+
+To compile kernels on another system, slightly alter the step-by-step guide's
+instructions:
+
+* Start following the guide on the machine where you want to install and test
+ the kernels later.
+
+* After executing ':ref:`Boot into the working kernel and briefly use the
+ apparently broken feature <bootworking_bissbs>`', save the list of loaded
+ modules to a file using ``lsmod > ~/test-machine-lsmod``. Then locate the
+ build configuration for the running kernel (see ':ref:`Start defining the
+ build configuration for your kernel <oldconfig_bisref>`' for hints on where
+ to find it) and store it as '~/test-machine-config-working'. Transfer both
+ files to the home directory of your build host.
+
+* Continue the guide on the build host (e.g. with ':ref:`Ensure to have enough
+ free space for building [...] <diskspace_bissbs>`').
+
+* When you reach ':ref:`Start preparing a kernel build configuration[...]
+ <oldconfig_bissbs>`': before running ``make olddefconfig`` for the first time,
+ execute the following command to base your configuration on the one from the
+ test machine's 'working' kernel::
+
+ cp ~/test-machine-config-working ~/linux/.config
+
+* During the next step to ':ref:`disable any apparently superfluous kernel
+ modules <localmodconfig_bissbs>`' use the following command instead::
-Further sources
----------------
+ yes '' | make localmodconfig LSMOD=~/lsmod_foo-machine localmodconfig
+
+* Continue the guide, but ignore the instructions outlining how to compile,
+ install, and reboot into a kernel every time they come up. Instead build
+ like this::
+
+ cp ~/kernel-config-working .config
+ make olddefconfig &&
+ make -j $(nproc --all) targz-pkg
+
+ This will generate a gzipped tar file whose name is printed in the last
+ line shown; for example, a kernel with the kernelrelease identifier
+ '6.0.0-rc1-local-g928a87efa423' built for x86 machines usually will
+ be stored as '~/linux/linux-6.0.0-rc1-local-g928a87efa423-x86.tar.gz'.
+
+ Copy that file to your test machine's home directory.
+
+* Switch to the test machine to check if you have enough space to hold another
+ kernel. Then extract the file you transferred::
+
+ sudo tar -xvzf ~/linux-6.0.0-rc1-local-g928a87efa423-x86.tar.gz -C /
+
+ Afterwards :ref:`generate the initramfs and add the kernel to your boot
+ loader's configuration <install_bisref>`; on some distributions the following
+ command will take care of both these tasks::
+
+ sudo /sbin/installkernel 6.0.0-rc1-local-g928a87efa423 /boot/vmlinuz-6.0.0-rc1-local-g928a87efa423
+
+ Now reboot and ensure you started the intended kernel.
+
+This approach even works when building for another architecture: just install
+cross-compilers and add the appropriate parameters to every invocation of make
+(e.g. ``make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- [...]``).
