[Linux-ia64] Q: stack coherency

Can I access a structure that's stored on the stack of one CPU from
another CPU? I'm just noisy because I always did that [e.g SysV message
code ipc/msg.c], and now a friend asked me if that's true for all cpu
architecures.

CPU1:
- initialize linked list element [local variable]
- spin_lock
- add to linked list
- spin_unlock
- ...


CPU2:
- spin_lock
- walk the linked list
- spin_unlock.
