Coincidently we're backporting another bugfix that needs the same prerequisites
as this one does.
You can cherry-pick those upstream commits:
80628ca06c5d kernel/fork.c:copy_process(): unify CLONE_THREAD-or-thread_group_leader code
0c740d0afc3b introduce for_each_thread() to replace the buggy while_each_thread()
1da4db0cd5c8 oom_kill: change oom_kill.c to use for_each_thread()
4449a51a7c28 vm_is_stack: use for_each_thread() rather then buggy while_each_thread()
The first two commits are prerequisites, and 1da4db0cd5c8 fixes a bug
we encountered.
