Move the kernel to end of the first 4 gigabytes of address space, so that

one 4 meg page can map both the kernel and the openfirmware mappings.
Add the openfirmware mappings to the kernel tsb so we can call the firmware
on the kernel trap table and access kernel memory normally.
Implement pmap_swapout_proc, pmap_swapin_proc, pmap_swapout_thread,
pmap_swapin_thread, pmap_activate, pmap_page_exists, and pmap_phys_address.
