799fbbdd10 _Actually_ move the kernel to the last TiB. 
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.

2597e2002b Get super basic ring3 task switching working 
* It looks like UEFI enables SSE, so we need to tell clang -mno-sse for
  now to not use XMM* until we're ready to save them.
* SYSCALL is working from ring3 tasks, calling console printf!
