64a6d88e5c Truly enable virtual memory.
Map is still identity-mapped. I think we need to sort and/or clean up

e19c7cee50 Give kernel image a header.
Kernel image now has a header with version, magic number, and a
pointer to its actual entrypoint. Entry point is now _start in
boot.s, and we now generate versions.s in the build tree for the
version macros.

Now the bootloader should be responsible for all initial setup,
loading the kernel, and then handing off to the kernel with
proper data in place.
