2656202dff init: disable all userland processes started from init 
In order to make the system easier to understand.

These include:

* networking
* klogd and syslogd. TODO what are those for? I could not see anything useful that they do.

Also get rid of the useless S20random thing while we are at it.

6e9f3dcf23 Document gem5 userland debugging 
This lead to an infinite chaing of refactorings:

Fix arm and aarch64 lx-symbols

This was just by chance, a continue GDB command was needed before running it.

I noticed that there is no more need for the x86 GDB --ex 'set arch i386:x86-64:intel'
thing and unified all archs. TODO bisect where that was fixed and understand why.

Add debug kernel configs for gem5 kernel.

Document gem5 aarch64 gdb debug doesn't work.

Document tmux split pane action.

29908dffb2 Disable networking at runtime with lkmc_nonet cli instead of build 
This is necessary because qemu and gem5 now use the same build folder.

Separate ./run -e and -f for kernel options before and after the ' - '.
This was already the better thing to do when -E was introduced,
but lkmc_nonet prompted me to do it nicer now.

Use the common script to find the out_dir on every toplevel script.

Include usage man pages on README.

36940cb322 Get rid of Maintainers section for lower level headers 
Move benchmark this repo out of conversation, there is plenty of action there!

Move kernel module sections and buildroot sections out of conversation.

Document the instruction count between baseline Buildroot and our monstrosity.

Put ./count-boot-instructions in a separate script.

Link to MIPS graphics QEMU question.

Link to VFIO QEMU question.

This is in preparation for moving parsec to 9p once we get it working on gem5.

We'll document it then when everything is working.
