Port to old kernel

@lacraig2 started working on this: https://github.com/rehosting/linux/tree/min_2.6
That patch series is slightly older than the ones we applied on main_4.10 (that branch was recently rebased to add default values for the kernel params which might matter)

[AndrewFasano]

Cole is fighting with compiling old kernels with modern toolchains. Got a base kernel to build with his container setup. Got min_2.6 branch to build - now need to compare diffs to figure out what's missing.

[AndrewFasano]

OSI is a bit broken because it's an older kernel. But we can just do without OSI

[AndrewFasano]

Cole is having difficulties building a kernel that works + runs with PANDA.

Trying to build vanilla kernels and get them running under PANDA

[AndrewFasano]

Cole has a kernel building that runs and we can interact with!

But all our patches are leading to crashes - something in do_sys_open (customized) broke as well as in other places - debugging

[AndrewFasano]

Can directly run initramfs with panda - but not working with full penguin setup

[AndrewFasano]

We'll deprioritize this task for the next sprint and re-evaluate in September

@alibobi focusing on 3.X kernels now instead of 2.6

[AndrewFasano]

Running into issues with root filesystem mounts.

I think @coolkingcole is also interested in a 5.X kernel - might be worth exploring in parallel or together

[AndrewFasano]

Ali is making progress on a 3.14 kernel - got it to see /dev/vda now need it to boot

[AndrewFasano]

Kernel runs, boots, there's a shell and a filesystem - but weird Illegal Instruction errors (arm guest) at the end of running any command - and then init dies.

Kernel is running, next steps port changes
