Fix possible deadlock reported by lockdep: qemu-system-s39/2963 is trying to acquire lock: (&mm->mmap_sem){++++++}, at: gmap_alloc_table+0x9c/0x120 but task is already holding lock: (&mm->mmap_sem){++++++}, at: gmap_map_segment+0xa6/0x27c Actually gmap_alloc_table is the only called in gmap_map_segment with mmap_sem held, thus it's safe to simply remove the inner lock.
