your 64bit xen_write_cr3_init, is just xen_write_cr3 without xen_get_user_pgd calling. plus set xen_write_cr3 to ops.write_cr3. so if you could have way to find out when xen_get_user_pgd could be used, new xen_write_cr3_init need to check that, then set ops.write_cr3 and call ops.write_cr3 otherwise will still call slim version without update ops.write_cr3 and bail out early.
