Subject: i386: extra checks in show_registers()
From: Chuck Ebbert <76306.1226@xxxxxxxxxxxxxx>
Sometimes thread_info and task_struct get out-of-sync with each other.
Printing task.thread_info in show_registers() can help spot this. And when
task_struct is corrupt then task.comm can contain garbage, so only print as
many characters as it can hold.
