Carsten Otte 499069e1a4 [S390] take mmap_sem when walking guest page table ... gmap_fault needs to walk the guest page table. However, parts of that may change if some other thread does munmap. In that case gmap_unmap_notifier will also unmap the corresponding parts from the guest page table. We need to take mmap_sem in order to serialize these operations. do_exception now calls __gmap_fault with mmap_sem held which does not get exported to modules. The exported function, which is called from KVM, now takes mmap_sem.
