Heiko Carstens d8ad075ef6 [S390] don't call handle_mm_fault() if in an atomic context. ... There are several places in the futex code where a spin_lock is held and still uaccesses happen. Deadlocks are avoided by increasing the preempt count. The pagefault handler will then not take any locks but will immediately search the fixup tables.
