Ciro Santilli 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.

Userland C programs used to test our kernel modules.

`sh` programs are simpler, and installed by copying directly with an overlay.

C programs require cross compiling, but give us more control over system calls.

These programs can also be compiled and used on host.
