[Xen-devel] Why we relocate xen location in __start_xen method?



in ARM Archietecture.
__start_xen ()

  ----->  setup_pagetables()
            {
                    /* Calculate virt-to-phys offset for the new location */
                      phys_offset = xen_paddr - (unsigned long) _start;

                     /* Copy */
                    memcpy((void *) dest_va, _start, _end - _start);
            }
