Better linux/initrd

[JZJisawesome]

Alrighty so the S-Mode kernel final works! That's great! But we still do have some work ahead of us (hopefully fun and not nearly as grueling).

Improvements are needed to the build-linux and linux repos:

• Add a branch for smode IRVE
• Add LETC branches
• Figure out a good way to create smode initrds (and mmode, but that is a lower priority)
• Automate initrd creation

Here's what busybox shows for my current experimental initramfs:

Hello Qemu!

Now we just need to get to this point with IRVE!

Massive improvements in recent PRs merged to IRVE, and commits to build-linux. Closing.
