You were faster than me. :-) Yes this is a totally ugly practice, I'll drop it.
That's for illustrative purposes. What'd be the right place and way to download
the Linux kernel? I'm sure we only need --depth=1. I imagine the following
approach:

1. In dev-env-setup, clone Linux sources (w/ or w/o --depth=1).
2. In openpower-isa Makefile, invoke the script on the kernel sources.
