Server product kernel requirements

[David Strauss]

I was, indeed, drawing an arbitrary line, but we must draw the line
somewhere. Maybe Fedora 23+ have it set far higher. It's easy to adapt over
time to support the high end of commodity servers while still being
desktop-friendly; we don't have a long support window.

My point is that HPC needs different options to the extent that the kernel
cannot be the same as desktop, cloud, and server.
