It is just so much easier to use tar + xz at build time, and leave the decompression task to the user. After decompression, the files will live on the disk and the page-cache mechanism will free memory when/if the files fall off the LRUs.
I'm also considering how generic and extensible the solution is. What if people need other build artifacts in the future (e.g. signing key to load signed modules)?
That sounds like it could be useful. I don't see any reason off the top why that would not be possible to add to the list of archived files in the future. The patch allows populating the list of files from Kbuild using ikh_file_list variable.
Um, no, you don't want the signing key in the kernel itself, as that totally defeats the purpose of the signing key :)
In a loadable module? He who has the module, can build and sign more modules.
