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!

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.
