Thank you. Yes, I did notice the delay the first time I tried to
download the tarball. I figured this would be a problem.

I'm currently configuring Buildroot for a company, so I want (need) to
provide links that will always work. I think what I will do is create
a davinci patch against a particular version of Linux and tell the
company to store the patch in their own source repository. That
guarantees that they can always get the file and re-recreate the same
same kernel - assuming kernel.org always has a copy of the original
kernel source for a particular version. :)
