ELFLoader works inside the kernel!
...
We load /_hello.o which just prints out a simple message.
It executes inside the kernel itself, so no fancy userspace process
or anything, but this is still so cool!

More paging stuff.
...
The test userspace process now runs at linear address 0x300000 which is
mapped to a dynamically allocated page from the MemoryManager. Cool!

A userspace process can now GPF and the OS goes on!
...
This is really rickety, but it kinda sorta works for my test GPF!

Add basic paging. Only identity maps the bottom 4MB as a start.

List the root directory after mounting /.
...
So cool that it works! It's spewing out a bunch of terminal escape sequences
that the OS console obviously doesn't support, but we'll get there too.

These changes were lying around uncommitted in the old repo.
...
I'm just gonna commit them without too much thinking and then take
it from there.

Import the "gerbert" kernel I worked on earlier this year.
...
It's a lot crappier than I remembered it. It's gonna need a lot of work.
