We've so far relied on manually compiling kernels on developer machines.
This means that we often lag behind vs released kernel.org versions.
The compiled kernels are stored in large-file storage which is awkward
to use and bloats the repository. There is also no way to validate that
the built artifacts have not been tampered with.
Add a GH Actions workflow which reads a list of versions from a JSON and
then builds the kernels. Selftests are only built for the latest stable
release, since keeping up with selftest breakage is just not worth it.
The existing ccache integration is used to make repeated builds of the
same kernels faster. This brings a very simple rebuild down to two
minutes or so.
The output of the build process is a single package with several tags
for each kernel version:
ghcr.io/cilium/ci-kernels:6.7-rc4
ghcr.io/cilium/ci-kernels:6.7
ghcr.io/cilium/ci-kernels:6.7-rc4-selftests
ghcr.io/cilium/ci-kernels:6.7-selftests
