CVE request - kernel: s390 task_show_regs infoleak

[Eugene Teo <eugene () redhat com>]

"task_show_regs used to be a debugging aid in the early bringup days of 
Linux on s390. /proc/<pid>/status is a world readable file, it is not a 
good idea to show the registers of a process. The only correct fix is to 
remove task_show_regs."

This does all the way back to 2.4.x.

Thanks, Eugene
