Gerald Schaefer d5feaea364 s390/mm: fix deadlock in unmap_hugepage_range() ... git commit cd2934a3 moved the flush_tlb_range() within __unmap_hugepage_range() inside the mm->page_table_lock, which triggered a deadlock in s390 tlb flushing code. __tlb_flush_mm_cond() also tries to acquire the mm->page_table_lock, but that is not needed because all callers already have mm->mmap_sem or mm->page_table_lock, so it can be safely removed to fix the deadlock.
