[PATCH] s390: in_interrupt vs. in_atomic
The condition for no context in do_exception checks for hard and soft interrupts by using in_interrupt() but not for preemption. This is bad for the users of __copy_from/to_user_inatomic because the fault handler might call schedule although the preemption count is != 0. Use in_atomic() instead in_interrupt().
