Martin Schwidefsky 44b6cc8130 s390/mm,kvm: flush gmap address space with IDTE ...

The __tlb_flush_mm() helper uses a global flush if the mm struct
has a gmap structure attached to it. Replace the global flush with
two individual flushes by means of the IDTE instruction if only a
single gmap is attached the the mm.
