Stop pretending that amd64 is i386. We're insulting the cpu by not even

pretending to use all the address space it gives us.

 - Map all physical memory 1-1 and implement PMAP_DIRECT
 - Remove the vast magic we do to map pages for pmap_zero_page,
   pmap_copy_page, pv allocation, magic while bootstrapping,
   reading of /dev/mem, etc.
 - implement a fast pmap_zero_page based on sse instructions.

I love removing code. More to come.
