    kernel - Refactor suword, fuword, etc.  change vmm_guest_sync_addr()
    
    * Rename the entire family of functions to reduce confusion.
    
    * Change how vmm_guest_sync_addr() works.  Instead of loading one value
      into a target location we exchange the two target locations, with the
      first address using an atomic op.  This will allow the vkernel to
      drop privs and query pte state atomically.
