bitkeeper revision 1.1159.1.564 (420b44edsb8XzPev-TiGW16GSsCW6g)
More x86_64 stuff. Added hypercalls to register a user-space pagetable,
modify FS/GS base addresses, and switch to user mode. User mode switches
back to kernel mode automatically on executing SYSCALL instruction.
Still todo: 1. getdomaininfo needs to include pagetable_user
2. get writable and shadow pagetables working
3. testing
