参数：

类型参数名称
kdb_reason_treason
kdb_reason_treason2
interror
kdb_dbtrap_tdb_result
struct pt_regs *regs
1400  result等于1
1402  当1循环
1408  当KDB_STATE(HOLD_CPU)循环
1413  如果非KDB_STATE(KDB)则KDB_STATE_SET(KDB)
1417  KDB_STATE_CLEAR(SUPPRESS)
1419  如果KDB_STATE(LEAVING)则退出
1422  result等于kdb_local - The main code for kdb
1425  如果result恒等于KDB_CMD_CPU则退出
1428  如果result恒等于KDB_CMD_SS则
1429  KDB_STATE_SET(DOING_SS)
1430  退出
1433  如果result恒等于KDB_CMD_KGDB则
1434  如果非KDB_STATE(DOING_KGDB)则kdb_printf("Entering please attach debugger or use $D#44+ or $3#33\n")
1437  退出
1439  如果result且result不等于1且result不等于Kernel Debugger Command codes. Must not overlap with error codes. 则kdb_printf("\nUnexpected kdb_local return code %d\n", result)
1443  退出
1445  如果KDB_STATE(DOING_SS)则KDB_STATE_CLEAR(SSBPT)
1451  返回:result
