Vasily Gorbik 8769f610fe s390/process: avoid potential reading of freed stack 
With THREAD_INFO_IN_TASK (which is selected on s390) task's stack usage
is refcounted and should always be protected by get/put when touching
other task's stack to avoid race conditions with task's destruction code.

Fixes: d5c352cdd0 ("s390: move thread_info into task_struct")
