_Actually_ move the kernel to the last TiB.

Browse Source 
More work on process page tables, including only mapping the last 2 pml4
entries (the highest 1TiB of the address space, ie, kernel space) into a
new table.

Includes the work of actually moving the kernel there, which I had
apparently done in name only previously. Oops.
