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 :)
