410  word等于0
413  当:size恒等于1
414  diag等于kdb_getphys - Read data from a physical address
415  如果非diag则word等于w1
417  退出
418  当:size恒等于2
419  diag等于kdb_getphys - Read data from a physical address
420  如果非diag则word等于w2
422  退出
423  当:size恒等于4
424  diag等于kdb_getphys - Read data from a physical address
425  如果非diag则word等于w4
427  退出
428  当:size恒等于8
429  如果size小于等于word的长度则
430  diag等于kdb_getphys - Read data from a physical address
431  如果非diag则word等于w8
433  退出
436  默认
437  diag等于KDB_BADWIDTH
438  kdb_printf("kdb_getphysword: bad width %ld\n", (long)size)
440  返回:diag
