Subject: [PATCH 4.4 0/7] fs/proc: Stop reporting eip and esp in

Reporting eip and esp fields on a non-current task is dangerous,
so backport this series for 4.4 to fix protential oops and info leak
problems. The first 3 patch are depended on the 6/7 patch.

Alexey Dobriyan (1):
  proc: fix coredump vs read /proc/*/stat race

Andy Lutomirski (3):
  sched/core: Allow putting thread_info into task_struct
  sched/core: Add try_get_task_stack() and put_task_stack()
  fs/proc: Stop reporting eip and esp in /proc/PID/stat

Heiko Carstens (1):
  sched/core, x86: Make struct thread_info arch specific again

John Ogness (2):
  fs/proc: Report eip/esp in /prod/PID/stat for coredumping
  fs/proc/array.c: allow reporting eip/esp for all coredumping threads
