[缺陷描述]：
使用iso安装龙芯系统后，无以下内核配置参数：
hardlockup_panic、softlockup_panic、watchdog_thresh、hung_task_timeout_secs、
hung_task_timeout_secs

查询softlockup_panic等内核参数：
[root@localhost ~]# ll  /proc/sys/kernel/hardlockup_panic
ls: cannot access '/proc/sys/kernel/hardlockup_panic': No such file or directory
[root@localhost ~]# ll /proc/sys/kernel/softlockup_panic
ls: cannot access '/proc/sys/kernel/softlockup_panic': No such file or directory
[root@localhost ~]# find / -name 'softlockup_panic'
find: ‘/proc/1300/task/1300/net’: Invalid argument
find: ‘/proc/1300/net’: Invalid argument
[root@localhost ~]# ll /proc/sys/kernel/watchdog_thresh
ls: cannot access '/proc/sys/kernel/watchdog_thresh': No such file or directory
[root@localhost ~]# ll /proc/sys/kernel/hung_task_timeout_secs
ls: cannot access '/proc/sys/kernel/hung_task_timeout_secs': No such file or directory
[root@localhost ~]# ll /proc/sys/kernel/hung_task_timeout_secs
ls: cannot access '/proc/sys/kernel/hung_task_panic': No such file or directory
